Our two-sided AvidPay Network of buyers and suppliers drives a powerful flywheel. We believe that by delivering a world-class AP automation experience, we attract more buyers and increase the number of transactions processed through our system. We also leverage our direct connections to our supplier network to increase penetration of electronic payments, which attracts more suppliers to our network. We capture more data from these additional transactions and e-payments that we use to continuously improve our AP automation experience, drawing more buyers, suppliers and, as a result, more transactions to our platform, which continues to fuel our organic growth. As we add more buyers to the AvidPay Network, both buyers and their suppliers benefit from our current network density which drives electronic payment adoption. In addition, new buyers bring new suppliers, thereby enabling us to continuously add more suppliers to the AvidPay Network and accelerating the flywheel of growth depicted below.

We sell our solutions through a hybrid go-to-market strategy that includes direct and indirect channels. Our direct sales force leverages their deep domain expertise in select verticals and over 120 referral relationships with integrated software providers, financial institutions and other partners to identify and attract buyers that would benefit from our AP software solutions and the AvidPay Network. Our indirect channel includes reseller partners and other strategic partnerships such as Mastercard, through MasterCard’s B2B Hub, which includes Fifth Third Bank and Bank of America, and other financial institutions, such as KeyBank, and third-party software providers such as MRI Software, RealPage and SAP Concur. Our referral and indirect channel partnerships provide us greater reach across the market to access a variety of buyers.

We have achieved significant growth through our recurring revenue business model, which gives us visibility into future periods and which is leading to increasing gross margins as we grow our revenue base. We generated revenue of $149.6 million in 2019 and $185.9 million in 2020, representing year-over-year growth of 24.3%. Our gross profit was $62.6 million in 2019 and $85.4 million in 2020, resulting in gross margin of 41.9% in 2019 and 45.9% in 2020. Our Non-GAAP gross profit was $78.6 million in 2019 and $102.3 million in 2020, resulting in Non-GAAP gross margin of 52.5% in 2019 and 55.0% in 2020. Our net loss was $93.5 million in 2019 and $101.2 million in 2020, and we have generated a net loss of more than $484.0 million since inception. See the section titled “Summary Consolidated

Risks Related to Our Business and Industry

We have a history of operating losses and we may not achieve or sustain profitability in the future.

We were incorporated in 2000 and have experienced net losses and negative cash flows from operations since inception. We generated net losses of $93.5 million and $101.2 million during the years ended December 31, 2019 and 2020, respectively. We generated net losses of $50.6 million and $92.0 million during the six months ended June 30, 2020 and 2021, respectively. We had an accumulated total stockholders’ deficit of $411.8 million and $511.1 million as of December 31, 2019, and December 31, 2020, respectively. Our losses and accumulated total stockholders’ deficit reflect the substantial investments we made in our people, products and services, and technology, and to acquire new buyers. While we have experienced significant revenue and transaction volume growth in recent years, we are not certain whether or when we will be able to achieve or maintain profitability in the future.

We also expect our costs and expenses to increase in future periods. In particular, we intend to continue to expend significant funds to invest in our people, products and services, technology, and the AvidPay Network and to expand our sales and marketing teams and invest in strategic partnerships and system integrations. We expect our general and administrative costs to also increase, but at a slower rate than our other operating expenses, for the foreseeable future. If we are not able to reduce or maintain the costs of providing our services, we could face competitive pricing pressure. If we are unable to continue to grow our revenue, or to reduce or maintain the costs of providing our services, we could continue to suffer increasing operating losses.

We may incur significant losses in the future for several reasons, including the other risks described herein, and unforeseen expenses, difficulties, complications, delays, and other unknown events. If we are unable to achieve and sustain profitability, the value of our business and stock may significantly decrease.

28

Our future revenue and operating results will be harmed if we are unable to acquire new customers, retain existing customers, expand sales to our existing customers, or develop new functionality for our platform that achieves market acceptance.

To continue to grow our business, it is important that we continue to attract new buyers and suppliers to use our platform. Our success in adding new buyers depends on numerous factors, including our ability to: (1) offer compelling AP automation products and services and features in the markets and industries we serve, (2) execute our sales and marketing strategy, (3) attract, effectively train and retain new sales, marketing, professional services, and support personnel in the markets we pursue, (4) develop or expand relationships with partners, payment providers, systems integrators, and resellers, (5) expand into new industry verticals, geographies, and market segments, which may require specific product and service features that we do not currently provide, (6) efficiently onboard new buyers on to our platform, (7) efficiently add more suppliers to our network and continue to drive increased adoption of electronic forms of payment, (8) execute a successful mergers and acquisitions strategy, and (9) provide additional paid services that complement the capabilities of our customers and their partners.

Our ability to increase revenue also depends in part on our ability to retain existing buyers and suppliers, sell more functionality and to increase product penetration to existing and new buyers and suppliers. Our buyers have no obligation to renew their subscriptions for our solutions after the expiration of their initial subscription period. In addition, some of our buyers can terminate their existing agreements with us prior to the expiration of the current contract terms. Our ability to increase sales to existing buyers depends on several factors, including their experience with implementing and using our platform, their ability to integrate our platform with other technologies, and our pricing model. Suppliers in our network select their preferred method of payment, which may include VCC, ACH, or check, based on their internal business rules, preferences, or perceived value, which may change at any time. Our ability to increase sales to suppliers already in our AvidPay Network depends on several factors, including their experience enrolling in and using our platform, development of new supplier product offerings, and our pricing model.

If we are unable to provide enhancements, new features, or keep pace with current technological developments, our business could be adversely affected. If our new functionality and services initiatives do not continue to achieve acceptance in the market and industries we serve, our competitive position may be impaired, and our potential to generate new revenue or to retain existing revenue could be diminished. The adverse effect on our financial results may be particularly acute because of the significant research, development, marketing, sales, and other expenses we will have incurred in connection with the new functionality and services.

Our historical growth may not be indicative of our future performance and we may not be able to sustain our growth rate, which is dependent on a number of factors that we do not control.

Although we have experienced significant historical revenue and transaction volume growth, we expect that, in the future, as our revenue and transaction volumes increase to higher levels, our growth rates may decline over time. Our revenue and transaction volume growth depends on a number of factors, including our ability to:

29

Further, the revenue that we derive from our invoice and payment transaction volume is dependent on several factors that we do not control. These factors include the number of invoices and payments submitted through our system, card brand interchange rates and tiers, payment amounts and types, the payment method selected by suppliers in our network, and competitive pricing pressure on products and incentives.

These factors make it difficult for us to control or forecast our future operating results and growth. If the assumptions we use to plan our business are incorrect or change, or if we are unable to maintain consistent revenue or revenue growth, it may be difficult to achieve and maintain profitability and the value of our business could be negatively impacted. You should not rely on our growth rates from any prior periods as any indication of our future growth.

We participate in highly competitive and fragmented markets, and our industry is rapidly evolving.

The AP and payments markets are highly fragmented and competitive and evolving. As businesses continue to adopt AP and payment automation solutions, we expect existing competitors and new market entrants to offer new and enhanced products and services and we expect the competitive environment to remain intense going forward. We currently compete on several factors, including:

Our current competitors range from other fintech companies and financial institutions to smaller, niche providers of software and services. We compete with companies that offer comprehensive solutions focused on the entire AP and payment processes and companies that focus only on select portions of these processes such as invoice and bill presentment, document and workflow management, AP and payment processing or accounts receivables. Solutions are also often specifically tailored to industry vertical or customer size making it difficult to expand into new verticals or attract larger or smaller customer types.

Accounting and ERP software providers, financial institutions, payment processing, and other service providers, a number of which we partner with in offering our solutions, may currently offer or develop solutions, acquire third-party solutions or competitors, or enter into strategic relationships that would enable them to expand their solutions to compete more effectively with our products and services. These parties may have access to larger, installed customer bases and may be able to effectively bundle and cross sell competitive solutions with their other services, which may enable them to compete more effectively or provide them with greater pricing and operating flexibility.

Companies that currently focus on providing solutions to enterprise businesses or SMBs may seek to expand the offering of their solutions to midmarket customers which would be more directly competitive with the products and services that we offer. New entrants not currently considered to be competitors may also enter the market through acquisitions, partnerships, or strategic relationships.

30

We often find that we are selling our products and services to potential customers that have not adopted a competing third-party solution and we must be able to convince internal stakeholders that our products and solutions are superior to their existing processes or third-party solutions.

For the reasons mentioned above, we may not be able to compete successfully against our current or future competitors, and this competition could result in the failure of our products and services to continue to achieve or maintain market acceptance, any of which would harm our business, operating results, and financial condition.

We transfer large sums of customer funds daily, and are subject to the risk of errors, which could result in financial losses and damage to our reputation and customer trust.

We processed approximately 53 million transactions for our customers in 2020. We have grown rapidly and seek to continue to grow, and although we maintain risk management processes, our business is always subject to the risk of financial losses as a result of operational errors, software defects, service disruption, third party fraud, employee misconduct, security breaches, credit losses, or other similar actions or errors. Furthermore, for 2018 to 2020, we identified a material weakness in our internal control over financial reporting relating to our reconciliation of funds held for customers. Our remediation efforts are ongoing and there can be no assurance that we will remediate this material weakness; further, we may experience additional material weaknesses in the future.

As a provider of AP and payment solutions, we collect and transfer funds on behalf of our customers. Software errors in our platform and operational errors by our employees and business partners may also expose us to losses. Moreover, our trustworthiness and reputation are fundamental to our business. As a provider of cloud-based software for complex back-office financial operations, the occurrence of any operational errors, software defects, service disruption, third party fraud, employee misconduct, security breaches, credit losses or other similar actions or errors on our platform could result in financial losses to our business and our customers, loss of trust, damage to our reputation, or termination of our agreements with strategic partners and accountants, each of which could result in:

Although our terms of service generally allocate to our customers the risk of loss resulting from our customers’ errors, omissions, employee fraud, or other fraudulent activity related to their systems, some of our customers may be able to negotiate changes to this position or in some instances we may cover such losses for efficiency or to prevent damage to our reputation, irrespective of fault or our terms of service. Although we maintain insurance to cover losses resulting from our errors and omissions, there can be no assurance that our insurance will cover all losses or our coverage will be sufficient to cover our losses. If we suffer significant losses or reputational harm as a result, our business, operating results, and financial condition could be adversely affected.

We, our strategic partners, our buyers and suppliers, and others who use our services obtain and process a large amount of data. Any real or perceived improper or unauthorized use of, exposure of, disclosure of, or access to such data could harm our reputation as a trusted brand, as well as have a material adverse effect on our business.

We, our strategic partners, our buyers and suppliers, and the third-party vendors and data centers that we use, obtain and process large amounts of data, including confidential information, along with personal and other data

31

related to our buyers and suppliers and their transactions, as well as other data of the counterparties to their payments. We face risks, including financial risks and risks to our reputation as a trusted brand, in the handling and protection of this data, and these risks will increase as our business continues to expand to include new products and technologies.

Cybersecurity incidents and malicious internet-based activity continue to increase generally, and providers of cloud-based services have frequently been targeted by such attacks. These cybersecurity challenges, including threats to our own IT infrastructure or those of our customers or third-party providers, may take a variety of forms ranging from stolen bank accounts, business email compromise, customer employee fraud, supply-chain attacks, ransomware, account takeover, check fraud, or cybersecurity attacks, to “mega breaches” targeted against cloud-based services and other hosted software, which could be initiated by individual or groups of hackers or sophisticated cyber criminals. A cybersecurity incident or breach could result in disclosure of data and intellectual property, or cause production downtimes and compromised data. We have in the past experienced cybersecurity incidents of limited scale. We may be unable to anticipate or prevent techniques used in the future to obtain unauthorized access or to sabotage systems because they change frequently and often are not detected until after an incident has occurred. As we increase our customer base and our brand becomes more widely known and recognized, third parties may increasingly seek to compromise our security controls or gain unauthorized access to our sensitive corporate information or our customers’ data.

We have administrative, technical, and physical security measures in place, and perform periodic penetration tests of our environment. We additionally have policies and procedures in place to contractually require service providers to whom we disclose data to implement and maintain reasonable privacy and security measures. However, if our protection or security measures or those of the previously mentioned third parties are inadequate or expose vulnerabilities or are breached as a result of third-party action, employee or contractor action or inaction, malfeasance, malware, phishing, hacking attacks, system error, software bugs or defects in our products, trickery, process failure, or otherwise, and, as a result, there is improper disclosure of, or someone obtains unauthorized access to or exfiltrates funds or sensitive information, including personally identifiable information, or PII, on our systems or our partners’ systems, or if we suffer a ransomware or advanced persistent threat attack, or if any of the foregoing is reported or perceived to have occurred, our reputation and business could be damaged. Recent high-profile security breaches and related disclosures of data by large institutions suggest that the risk of such events is significant, even if privacy protection and security measures are implemented and enforced. If sensitive information is lost or improperly disclosed or threatened to be disclosed, we could incur significant costs associated with remediation and the implementation of additional security measures, and may incur significant liability and financial loss, and be subject to regulatory scrutiny, investigations, proceedings, and penalties.

In addition, if our financial institutions or strategic partners conclude that our systems and procedures are insufficiently rigorous, they could terminate their relationships with us, and our financial results and business could be adversely affected. If there is a breach of the information that we store, we could be liable to our partners for their losses and related expenses. Additionally, if our own confidential business information were improperly disclosed, our business could be materially and adversely affected. A core aspect of our business is the reliability and security of our platform. Any perceived or actual breach of security, regardless of how it occurs or the extent of the breach, could have a significant impact on our reputation as a trusted brand, cause us to lose existing partners or other customers, prevent us from obtaining new partners and other customers, require us to expend significant funds to remedy problems caused by breaches and implement measures to prevent further breaches, and expose us to legal risk and potential liability including those resulting from governmental or regulatory investigations, class action litigation, and costs associated with remediation, such as fraud monitoring and forensics. Any actual or perceived security breach at a company providing services to us or our customers could have similar effects.

While we maintain cybersecurity insurance, our insurance may be insufficient or may not cover all liabilities incurred by such incidents. We also cannot be certain that our insurance coverage will be adequate for data

32

handling or data security liabilities actually incurred, that insurance will continue to be available to us on economically reasonable terms, or at all, or that any insurer will not deny coverage as to any future claim. The successful assertion of one or more large claims against us that exceed available insurance coverage, or the occurrence of changes in our insurance policies, including premium increases or the imposition of large deductible or co-insurance requirements, could have a material adverse effect on our business, including our financial condition, operating results, and reputation.

We earn a substantial portion of our revenue from electronic payment transactions and our growth is dependent upon the continued acceptance, security and adoption of electronic payment types that result in interchange revenue.

We earn a substantial portion of our revenue from VCC and ACH payment transactions paid to suppliers in our network and our growth is dependent upon the continued acceptance, security, and adoption of electronic payment types that result in interchange revenue on the amount of the transactions. During the fiscal year ended December 31, 2020, we earned approximately $109.6 million in revenue from VCC and AvidPay Direct paid through our network.

Although we expect businesses to continue to accept and adopt electronic forms of payment, we do not mandate a specific payment type in our network and the adoption rates of electronic payments in AP transactions could erode or grow more slowly than expected. Suppliers in our network select their preferred method of payment, which may include VCC, ACH, or check, based on their internal business rules, preferences, or perceived value, which may change at any time. Additionally, accounts receivable, or AR, service providers market and sell their AR services to suppliers and groups of supplier types in our network. These service providers may not accept electronic payments and may convert existing suppliers in our network that accept electronic payments to check. Suppliers in our network, and those AR service providers, may, with or without advance notice, prohibit or impose restrictions on the methods we use to provide or deliver electronic payments that we may not be aware of or be able to comply with, seek to negotiate reduced pricing, or charge fees in order to accept electronic payments. Certain industries and verticals are also less inclined to accept electronic forms of payment which may limit our ability to successfully expand into new industries or verticals.

The revenue we receive from electronic payment transactions is also dependent upon number of factors, many of which we do not control, including the continued acceptance and adoption by businesses of electronic payments, interchange rates which may decline over time, fees charged by suppliers to accept electronic payments, buyer incentives, and the terms of our commercial agreements with third-party service providers that are involved in the payment process. Widespread adoption of new forms of electronic payments, such as real time payments, could also negatively impact the revenue we receive from electronic payment transactions.

If we lose key members of our team including our Co-Founder and Chief Executive Officer, or if we are unable to attract and retain talent, our business may be harmed.

Our success and future growth depend upon the continued services of our team and other key employees. Our Co-Founder and Chief Executive Officer, Michael Praeger, is critical to our overall strategic direction, our culture, and the development of key products, partnerships and relationships. Our senior management and key employees are employed on an at-will basis. The loss of our chief executive officer, one or more members of our senior management, or other key employees, could harm our business, and we may not be able to find adequate replacements.

To execute our business strategy, we must attract and retain highly qualified personnel. Our headquarters and primary center of employment is in Charlotte, North Carolina. In general, the talent pool in Charlotte may be smaller than in other geographic areas. Competition for executive officers, software developers and engineers, compliance and risk management personnel, and other key employees in our industry and location is intense and increasing, and we may not be able to attract the talent we need to grow and succeed. We compete with many other companies for software developers with high levels of experience in designing, developing, and managing cloud-based software and payment systems, as well as for skilled legal and compliance and risk operations

33

professionals. The current regulatory environment related to immigration may increase the likelihood that immigration laws may be modified to further limit the availability of H1-B and other visas. If a new or revised visa program is implemented, it may impact our ability to recruit, hire, retain or effectively collaborate with qualified skilled personnel, including in the areas of AI and ML, and payment systems and risk management, which could adversely impact our business, operating results and financial condition. Many of the companies with which we compete for experienced personnel have greater resources than we do and can frequently offer such personnel substantially greater compensation than we can offer, and may be in geographies perceived by some employees as more desirable. If we fail to identify, attract, develop, and integrate new personnel, or fail to retain and motivate our current personnel, our growth prospects would be adversely affected.

We may not be able to scale our business and technology quickly enough to meet our growth.

As we continue to grow and process additional transactions, and as we sign additional strategic partners, we will need to devote additional resources to improving and maintaining our infrastructure and computer network and integrating with third-party applications to maintain the performance of our platform. In addition, we will need to appropriately scale our internal business systems and our services organization, including customer support, risk and compliance operations, and professional services, to serve our growing customer base.

We have also experienced, and may in the future experience, disruptions, outages and other performance problems that interfere with our customers’ ability to access and use our products and services. These events may be due to a variety of factors, including capacity constraints due to increased use and transaction volumes, legacy infrastructure, architecture, code and processes, and software and human errors. It may become increasingly difficult to maintain and improve the performance of our platform and our products and services especially during peak usage times and as our solutions become more complex.

Any failure of or delay in our efforts to maintain, improve and scale our technology, infrastructure and platform could result in service interruptions, impaired system performance, and reduced customer satisfaction, resulting in decreased sales to new customers, lower renewal rates by existing customers, or requested refunds, all of which could hurt our revenue growth. Even if we are successful in these efforts to scale our business, they will be expensive and complex, and require the dedication of significant management time and attention. We could also face inefficiencies or service disruptions as a result of our efforts to scale our internal infrastructure. We cannot be sure that the expansion and improvements to our internal infrastructure will be effectively implemented on a timely basis, if at all, and such failures could adversely affect our business, operating results, and financial condition.

We may lose existing customers or fail to attract new customers if we are unable to deliver new software, solutions and technology for our platform.

Our success depends on our continued development of new and improved AP automation software and payment solutions and related technology and the continued automation of payments processes. If we are unable to deliver new products or services, or to enhance existing products and services, that achieve market acceptance or if we are unable to integrate technology, products and services that we acquire into our platform, our business could be adversely affected through increased attrition of current customers or slower addition of new customers. We have experienced, and may in the future experience, delays in the planned release dates of enhancements to our platform, and we have discovered, and may in the future discover, errors in new releases after their introduction. Either situation could result in adverse publicity, loss of sales, delay in market acceptance of our platform or customer claims, including, among other things, warranty claims against us, any of which could cause us to lose existing customers or affect our ability to attract new customers.

Interruptions or delays in the services provided by third-party data centers or internet service providers could impair the delivery of our products and services.

We host our products and platform on a hybrid cloud platform leveraging public cloud infrastructure services and co-located infrastructure in datacenter facilities. Public cloud services are provided by Microsoft Azure, and

34

others which include infrastructure as a service and platform as a service technologies. All products utilize resources operated by us through these providers, therefore, we depend on these third parties to protect their data centers against damage or interruption from natural disasters, power or telecommunications failures, criminal acts, and similar events. We have periodically experienced service disruptions in the past, and we cannot assure you that we will not experience interruptions or delays in our service in the future. Many of our core products are run in production from a single data center in Charlotte, North Carolina. If that data center were not available to us due to damage or otherwise, we would have to operate using our disaster recovery plan, as we do not have a fully redundant system for all of our core functions. This could cause substantial disruption in our operations if we were not able to move our main processes in a timely manner to a backup data center. We may also incur significant costs for using alternative equipment or taking other actions in preparation for, or in reaction to, events that damage the data storage services we use.

Although we have disaster recovery plans, any incident affecting their infrastructure that may be caused by fire, flood, severe storm, earthquake, power loss, telecommunications failures, unauthorized intrusion, computer viruses and disabling devices, natural disasters, military actions, terrorist attacks, negligence, and other similar events beyond our control could negatively affect our platform. Any prolonged service disruption affecting our platform for any of the foregoing reasons could damage our reputation with current and potential customers, expose us to liability, cause us to lose customers, or otherwise harm our business. System failures or outages, including any potential disruptions due to significantly increased global demand on certain cloud-based systems during the COVID-19 pandemic, could compromise our ability to perform these functions in a timely manner, which could harm our ability to conduct business or delay our financial reporting.

Our platform is accessed by many customers, often at the same time. As we continue to expand the number of our customers and products available to our customers, we may not be able to scale our technology to accommodate the increased capacity requirements, which may result in interruptions or delays in service. In addition, the failure of data centers, internet service providers, or other third-party service providers to meet our capacity requirements could result in interruptions or delays in access to our platform or impede our ability to grow our business and scale our operations. If our third-party infrastructure service agreements are terminated, or there is a lapse of service, interruption of internet service provider connectivity, or damage to data centers, we could experience interruptions in access to our platform as well as delays and additional expense in arranging new facilities and services.

Moreover, we are currently executing on a long-term strategy to transition to public cloud services completely and decommission on-premise infrastructure hosted in co-located datacenters. As this transition occurs, it is possible that the availability of the platform may be impacted and outages or disruptions may occur. Although we have a disaster recovery program, it does not yet provide full redundancy, so there will be a period of time that our platform will remain shut down while the transition to the back-up data centers take place. We were informed in June 2021 that our current lease for our core data center in Charlotte will terminate in September 2022. We will have to either accelerate our move of our infrastructure to public cloud services, or move the existing data center operations to a new location. Any service disruption affecting our platform during such migration or while operating on the Azure cloud infrastructure could damage our reputation with current and potential customers, expose us to liability, cause us to lose customers, or otherwise harm our business.

Future acquisitions, strategic investments, partnerships, collaborations, or alliances could be difficult to identify and integrate, divert the attention of management, disrupt our business, dilute stockholder value, and adversely affect our operating results and financial condition.

Like we have in the past with our acquisitions of Piracle, Strongroom, Ariett, Entryless, BankTEL, and Core Associates and most recently FastPay, we may in the future seek to acquire or invest in businesses, products, or technologies that we believe could complement or expand our platform, enhance our technical capabilities, or otherwise offer growth opportunities. The pursuit of potential acquisitions may divert the attention of management and cause us to incur various expenses in identifying, investigating, and pursuing suitable

35

acquisitions, whether or not such acquisitions are completed. In addition, we may not successfully identify desirable acquisition targets, or if we acquire additional businesses, we may not be able to integrate them effectively following the acquisition or effectively manage the combined business following the acquisition. Integration may prove to be difficult due to the necessity of integrating personnel with disparate business backgrounds and accustomed to different corporate cultures.

We also may not achieve the anticipated benefits from any acquired business due to a number of factors, including:

Acquisitions could result in lower cash reserves, possible dilutive issuances of equity securities or the incurrence of debt, as well as unfavorable accounting treatment. Any such issuances of additional capital stock may cause stockholders to experience significant dilution of their ownership interests and the per share value of our common stock to decline. In addition, a significant portion of the purchase price of any companies we acquire may be allocated to acquired goodwill and other intangible assets, which must be assessed for impairment at least annually. We also may not generate sufficient financial returns to offset the costs and expenses related to any acquisitions. If our acquisitions do not yield expected returns, we may be required to take charges to our results of operations based on this impairment assessment process, and our business, operating results and financial condition may suffer.

Failure to effectively develop and expand our sales and marketing capabilities could harm our ability to increase our base of buyers and suppliers and achieve broader market acceptance of our products.

Our ability to increase our base of buyers and suppliers and achieve broader market acceptance of our platform will depend to a significant extent on our ability to expand our sales and marketing organizations, and to deploy our sales and marketing resources efficiently. We plan to continue expanding our direct sales force as well as our sales force focused on identifying new strategic and indirect sales partners. We also dedicate significant resources to sales and marketing programs. Our business and operating results will be harmed if those efforts do not generate significant increases in revenue. We may not achieve anticipated revenue growth from expanding our sales force if we are unable to hire, develop, integrate, and retain talented and effective sales personnel, if our new and existing sales personnel are unable to achieve desired productivity levels in a reasonable period of time, or if our sales and marketing programs and advertising are not effective.

We are subject to the payment card network rules and our failure to comply with these rules could harm our business.

We use Mastercard branded VCCs exclusively in connection with our VCC payment service and we are subject to payment card network operating rules, including the Payment Card Industry Data Security Standard, or PCI-DSS. The payment card networks set and interpret the card operating rules and could adopt new operating rules

36

or interpret or reinterpret existing rules that we or our processors might find difficult or even impossible to follow, or costly to implement. AvidXchange was not previously PCI-DSS compliant, but recently obtained its PCI-DSS certification. There can be no assurances that AvidXchange will be able to maintain this certification. Failure to maintain this certification, or any prior or future violations of existing or new rules of the payment card network, or increased fees, could result in the revocation of our ability to make payments using VCCs, or such payments could become prohibitively expensive for us or for our customers. If we are unable to make buyer payments to suppliers using VCCs, our business would be adversely affected. We also may seek to introduce other card-related products in the future which may entail additional operating rules.

If we fail to maintain or grow our brand recognition, our ability to expand our base of suppliers and buyers will be impaired and our financial condition may suffer.

We believe that growing the AvidXchange brand is important to supporting continued acceptance of our existing and future solutions, attracting new buyers and suppliers to our platform, and retaining existing buyers and suppliers. We also believe that the importance of brand recognition will increase as competition in our market increases. Successfully maintaining our brand will depend largely on the effectiveness of our marketing efforts, our ability to provide a reliable and useful platform to meet the needs of our customers at competitive prices, our ability to maintain our customers’ trust, our ability to continue to develop new functionality and solutions, and our ability to successfully differentiate our platform. Additionally, our partners’ performance may affect our brand and reputation if customers do not have a positive experience. Brand promotion activities may not generate customer awareness or yield increased revenue. Even if they do, any increased revenue may not offset the expenses we incurred in building our brand. If we fail to successfully promote and maintain our brand, we may fail to attract enough new customers or retain enough existing customers to realize a sufficient return on our brand-building efforts, and our business could suffer.

In connection with our financial statement close process for the year ended December 31, 2020, material weaknesses were identified in the design and operating effectiveness of our internal control over financial reporting. If we fail to develop and maintain effective internal control over financial reporting, we may not be able to accurately and timely report our financial results, which may adversely affect investor confidence in us.

In connection with the preparation of our financial statements for the year ended December 31, 2020, we and our independent registered public accounting firm identified certain control deficiencies in the design of our internal control over financial reporting that constituted material weaknesses as of December 31, 2020. A material weakness is a deficiency, or a combination of deficiencies, in internal control over financial reporting such that there is a reasonable possibility that a material misstatement of our financial statements will not be prevented or detected on a timely basis. Our evaluation was based on the Committee of Sponsoring Organizations of the Treadway Commission (COSO) Internal Control—Integrated Framework (2013). These material weaknesses are as follows:

These material weaknesses resulted in material misstatements related to our preferred stock, additional-paid-in-capital accounts, and the classification of cash flows from operating and investing activities as of and for the year ended December 31, 2019, which resulted in the restatement of the 2019 consolidated financial statements, errors identified and corrected in the aforementioned accounts as of and for the periods ended December 31, 2020 and June 30, 2021, and in immaterial misstatements related to our cost of revenues, sales and marketing expense,

37

research and development expense, general and administrative expense, and additional-paid-in-capital accounts, which resulted in the revision of our December 31, 2020 and June 30, 2021 financial statements.

Additionally, these material weaknesses could result in a misstatement of substantially all of our accounts or disclosures that such material weaknesses could result in a material misstatement to the annual or interim consolidated financial statements that would not be prevented or detected. As of the date of this prospectus we have taken the following steps as part of our remediation plan.

As of the date of this prospectus we are in the process of implementing the following steps of our remediation plan.

We believe the material weaknesses will be fully remediated in 2022, at which time we believe we will have implemented and tested review controls executed by our newly hired resources. We have incurred certain costs associated with the aforementioned remediation activities completed to date, which are reflected in our historical financial statements, and do not expect to incur material costs related to our remaining remediation efforts.

While we believe these efforts will remediate the material weaknesses, we may not be able to complete our evaluation, testing or any required remediation in a timely fashion, or at all. We cannot assure you that the measures we have taken to date and may take in the future will be sufficient to remediate the control deficiencies that led to the identified material weaknesses in internal control over financial reporting or that the measures will prevent or avoid future material weaknesses. The effectiveness of our internal control over financial reporting is subject to various inherent limitations, including cost limitations, judgments used in decision making, assumptions about the likelihood of future events, the possibility of human error and the risk of fraud. If we are unable to remediate the material weaknesses, our ability to record, process and report financial information accurately, and to prepare financial statements within the time periods required under SEC rules, could be

38

adversely affected. This may in turn adversely affect our reputation and business and the market price of our common stock. In addition, any such failures could result in litigation or regulatory actions by the SEC or other regulatory authorities, loss of investor confidence, delisting of our common stock, and diversion of financial and management resources from the operation of our business.

Customer funds held by us are subject to market, interest rate, credit, and liquidity risks, as well as general political and economic conditions. The loss of these funds could have a material adverse effect on our business, financial condition, and results of operations.

We arrange for funds of our customers, including funds that will be remitted to suppliers, to be held in trust in cash or cash equivalents, and these funds may be invested in highly liquid, investment-grade marketable securities and money market securities from time to time. Nevertheless, our customer fund assets are subject to general market, interest rate, credit, and liquidity risks. These risks may be exacerbated, individually or in aggregate, during periods of heavy financial market volatility. In the event of a financial crisis, such as that experienced in 2008 and such as that which has resulted, or may result, from the COVID-19 pandemic or other similar events, employment levels and interest rates may decrease with a corresponding impact on our business. As a result, we could experience a constriction in the availability of liquidity, which may impact our ability to fulfill our obligations to enable the movement of customer funds to the intended recipients. Additionally, we rely upon certain banking partners and other third parties to originate ACH payments, process checks, execute wire transfers, and issue VCCs, and these banking partners and other third parties could be similarly affected by a liquidity shortage, which may further exacerbate our ability to operate our business. Any material loss of or inability to access customer funds could have an adverse impact on our cash position and results of operations, could require us to obtain additional sources of liquidity, and could have a material adverse effect on our business, financial condition, and results of operations.

We are licensed as a money transmitter (or statutory equivalent) in all U.S. jurisdictions where, to the best of our knowledge, licensure is required for our business. Accordingly, we are subject to direct regulation by the licensing authorities of the jurisdictions where we are licensed. In certain jurisdictions where we operate, we are required to hold eligible liquid assets, as defined by the relevant regulatory authority, equal to at least 100% of the aggregate amount of any outstanding customer liabilities. Our ability to manage and accurately account for the assets underlying our customer funds and comply with applicable liquid asset requirements requires a high level of internal controls. As our business continues to grow and we expand our product offerings, it may be necessary to scale the applicable internal controls. Our success requires significant public confidence in our ability to properly manage our customers’ balances and handle large and growing transaction volumes and amounts of customer funds. Any failure to maintain the necessary controls or to accurately manage our customer funds and the assets underlying our customer funds in compliance with applicable regulatory requirements could result in reputational harm, lead customers to discontinue or reduce their use of our products, and result in significant penalties and fines, up to and including the loss of our state money transmitter licenses, which would materially harm our business.

We depend on banks, bank partners and other third-party service providers to process transactions.

We depend on bank partners and other third-party service providers, including KeyBank, Comdata Inc., Fiserv Solutions and Fidelity Information Services, to process electronic payment transactions and check payments for our customers. We have entered into treasury services agreements and other arrangements with our bank partners and other third-party service providers for payment processing and related services. If these arrangements are terminated for any reason, or if services provided by our bank partners and other third-party service providers are interrupted, we could experience delays, interruptions, and additional costs in processing payments for our customers.

We also depend on third-party service providers for other critical functions, including customer invoicing and scanning solutions. We have entered into service agreements with these third-party service providers for

39

scanning, indexing and related services, and these agreements include significant security, compliance, and operational obligations. If our agreements with the scanning and/or indexing partners are terminated for any reason, we could experience service interruptions as well as delays and additional expenses in arranging for new services.

Our business depends, in part, on our relationships with providers of accounting and ERP solutions.

Our relationships with accounting and ERP solutions partners are integral to our ability to deliver our products and services to our customers. We rely upon their cooperation to develop and maintain integrations between our products and services and their respective solutions. These integrations allow information to be communicated between our products and services and our customers’ accounting systems. These partners may also market and promote our products and services to customers. We may also compete with accounting and ERP solution providers from time to time that have developed or offer third party products and services that are competitive with our products and services.

If our current partners decided instead to design their own AP solutions, that could harm our business.

If we were unable to continue these relationships and add relationships with new accounting and ERP solutions partners, our growth prospects could be negatively impacted by not being able to offer necessary integrations to customers.

Our long-term growth strategy depends, in part, on strategic partnerships and indirect sales partners.

We intend to continue to expand our current strategic partner relationships and to develop new strategic partner relationships to expand our sales and marketing efforts that we believe will allow us to sell and market our services in existing and new markets. Establishing strategic partner relationships, particularly with our financial institution customers and accounting software providers, entails extensive and highly specific upfront sales efforts, with little predictability and various ancillary requirements.

For example, our partners may require us to submit to an exhaustive security audit, given the sensitivity and importance of storing their customer billing and payment data on our platform. As a result, formalizing and maintaining new strategic partner relationships involve a degree of effort and risks that may not be present or that are present to a lesser extent with direct customer sales. With strategic partners, the decision to enter into a relationship with us frequently requires the approval of multiple management personnel and technical personnel. Additionally, sales to strategic partners’ customers may require us to invest more time educating and selling to these potential customers. Purchases of our services by customers of strategic partners are also frequently subject to delays and considerable efforts to negotiate and document relationships with them. Further, we may integrate our platform with our strategic partners’ own websites and apps, which requires significant time and resources to design and deploy both before and after marketing and sales efforts begin. If we are unable to increase sales of our services through strategic partners and to manage the costs associated with these relationships, including without limitation, integrating with their systems and ongoing training for their marketing and sales personnel, our business, financial position, and operating results may be adversely affected.

Our ability to attract new strategic partners may be limited by our commitments to provide our existing strategic partners with certain exclusivity and/or first rights to participate in certain channels or territories. We also may not be able to attract new strategic partners if our potential partners favor our competitors’ products or services over our services or choose to compete with our services directly. Certain of our strategic partners may have the resources and inclination to develop their own solutions to replace ours. Moreover, strategic partners could decide to focus on other market segments. Further, there can be no guarantee that our strategic partners will not choose to terminate their relationships with us for strategic or other reasons. If we are unsuccessful in establishing, growing, or maintaining our relationships with strategic partners, our ability to compete in the marketplace or to grow our revenue could be impaired, and our results of operations may suffer.

40

The loss of one or more of our key buyers or strategic partners could negatively affect our ability to market our platform.

We rely on our reputation and recommendations from key buyers and strategic partners in order to promote our platform. The loss of any of our key buyers or strategic partners could have a significant impact on our revenues, reputation and our ability to obtain new customers. Some of our key customers have the ability to terminate their existing agreements without cause prior to the expiration of the applicable term. In addition, acquisitions of our buyers could lead to cancellation of our contracts with those customers or by the acquiring companies, thereby reducing the number of our existing and potential customers.

If we cannot maintain our company culture as we grow, we could lose the innovation, teamwork, passion and focus on execution that we believe contribute to our success and our business may be harmed.

We believe that a critical component of our success has been our company culture, which is based on our core values of ensuring customer success, focusing on results and striving for excellence. We have invested substantial time and resources in building our team within this company culture. As we grow and develop the infrastructure of a public company, we may find it difficult to maintain these important aspects of our company culture. If we fail to preserve our culture, our ability to retain and recruit personnel and to effectively focus on and pursue our corporate objectives could be compromised, potentially harming our business.

If we fail to offer high-quality customer support, or if our support is more expensive than anticipated, our business and reputation could suffer.

Both our buyers and suppliers rely on our customer support services to resolve issues and realize the full benefits provided by our products and services. High-quality support is also important for the renewal and expansion of our products and services with existing customers. We primarily provide customer support over chat, email and phone-based support. If we do not help our customers quickly resolve issues and provide effective ongoing support, or if our support personnel or methods of providing support are insufficient to meet the needs of our customers, our ability to retain customers, increase the density of our supplier network and acquire new customers could suffer, and our reputation with existing or potential customers could be harmed.

Uncertain or weakened economic conditions, including as a result of COVID-19, may adversely affect our industry, business and results of operations.

Our overall performance depends on economic conditions, which may be challenging at various times in the future. Financial developments seemingly unrelated to us or our industry may adversely affect us. Domestic and international economies have from time-to-time been impacted by falling demand for a variety of goods and services, tariffs and other trade issues, threatened sovereign defaults and ratings downgrades, restricted credit, threats to major multinational companies, poor liquidity, reduced corporate profitability, volatility in credit, equity and foreign exchange markets, bankruptcies and overall uncertainty. For example, COVID-19 has created and may continue to create significant uncertainty in global financial markets and the long-term economic impact of COVID-19 is highly uncertain. We cannot predict the timing, strength or duration of the current or any future potential economic slowdown in the United States or globally. These conditions affect the rate of technology spending generally and could adversely affect our customers’ ability or willingness to use our services, delay prospective customers’ purchasing decisions or reduce the value of payments made on our network, any of which could adversely affect our results of operations.

Natural catastrophic events and man-made problems such as power-disruptions, computer viruses, data security breaches, and terrorism may disrupt our business.

Natural disasters or other catastrophic events may cause damage or disruption to our operations, international commerce and the global economy, and thus could harm our business. We have a large employee presence in

41

Charlotte, North Carolina and smaller employee groups in Houston, Texas, Salt Lake City, Utah, Birmingham, Alabama, Columbus, Mississippi, Somerset, New Jersey and Pembroke, Massachusetts, and our primary co-located data center is located in North Carolina. In the event of a major earthquake, hurricane or catastrophic event such as fire, power loss, telecommunications failure, vandalism, cyber-attack, war, or terrorist attack, we may be unable to continue our operations and may endure system interruptions, reputational harm, delays in our application development, lengthy interruptions in our products, breaches of data security, and loss of critical data, all of which could harm our business, operating results, and financial condition.

Additionally, as computer malware, viruses, and computer hacking, fraudulent use attempts, phishing attacks, and other data security breaches have become more prevalent, we, and third parties upon which we rely, face increased risk in maintaining the performance, reliability, security, and availability of our solutions and related services and technical infrastructure to the satisfaction of our customers. Any such data security breach related to our network infrastructure or information technology systems or to computer hardware we lease from third parties, could, among other things, harm our reputation and our ability to retain existing customers and attract new customers.

In addition, the insurance we maintain may be insufficient to cover, or may not cover, our losses resulting from disasters, cyber-attacks, or other business interruptions, and any incidents may result in loss of, or increased costs of, such insurance.

The COVID-19 outbreak has materially impacted the U.S. and global economies and could have a material adverse impact on our employees, customers and strategic partners.

Beginning in March 2020, the outbreak of COVID-19, or coronavirus, caused by a novel strain of the coronavirus became increasingly widespread in the United States and worldwide. Many jurisdictions in the United States have limited social mobility and gathering. Many business establishments have closed or restricted hours or operations due to restrictions imposed by the government and many governmental authorities have closed or restricted hours or operations of public establishments, including schools, restaurants and shopping malls. The outbreak has had, and may continue to have for the foreseeable future, a significant negative impact on general economic conditions in both the United States and abroad.

Many of our customers have been, and will likely continue to be, negatively impacted by the pandemic and the resulting national, state and local orders and the increase in unemployment. These conditions will likely continue to have negative implications on the demand for goods and services, real estate, public services, the supply chain and the production of goods and transportation which could in turn have a negative impact on our customers and the number of transactions that we process through our systems.

In response to the outbreak, AvidXchange shifted to a work-from-home environment in accordance with its business continuity policy and modified existing business practices particularly around employee travel and the cancellation of physical participation in meetings, events and conferences including our annual customer conference. We may take further action in response to the pandemic and as may be required by government authorities.

The COVID-19 pandemic may also continue to adversely impact our employees and our productivity and the operations of our customers and our strategic partners. The disruption caused by the pandemic may negatively impact our ability to meet customer demand and our revenue and profit margins and we may experience delays or changes in customer demand, particularly if customer funding priorities change.

In addition, the disruption and volatility in the global and domestic capital markets caused by the pandemic may increase the cost of capital and limit our ability to access capital.

Both the health and economic aspects of the pandemic are highly fluid and the future course of each is uncertain. For these reasons and other reasons that may come to light if the COVID-19 pandemic and associated protective

42

or preventative measures expand, we may experience a material adverse impact on our business operations, revenues and financial condition; however, its ultimate impact is highly uncertain and subject to change.

Our risk management efforts may not be effective to prevent fraudulent activities by our customers or their counterparties or third parties, which could expose us to material financial losses and liability and otherwise harm our business.

We offer products and services, including software, that digitize and automate back-office financial operations for a large number of buyers and execute payments to their suppliers. We are responsible for verifying the identity of our buyers and their users, and monitoring transactions for fraud. We and our buyers and our suppliers have been in the past, and will continue in the future to be, targeted by parties who seek to commit acts of financial fraud using techniques such as stolen identities and bank accounts, compromised business email accounts, employee or insider fraud, account takeover, false applications, and check fraud. We may suffer losses from acts of financial fraud committed by our buyers and suppliers and their users, our employees or third-parties.

The techniques used to perpetrate fraud on our platform are continually evolving. In addition, when we introduce new products and functionality, or expand existing products, we may not be able to identify all risks created by the new products or functionality. Our risk management policies, procedures, techniques, and processes may not be sufficient to identify all of the risks to which we are exposed, to enable us to prevent or mitigate the risks we have identified, or to identify additional risks to which we may become subject in the future. Furthermore, our risk management policies, procedures, techniques, and processes may contain errors or our employees or agents may commit mistakes or errors in judgment as a result of which we may suffer large financial losses. The software-driven and highly automated nature of our platform could enable criminals and those committing fraud to steal significant amounts of money from businesses like ours. As greater numbers of customers use our platform, our exposure to material risk losses from a single customer, or from a small number of customers, will increase.

Our current business and anticipated growth will continue to place significant demands on our risk management efforts, and we will need to continue developing and improving our existing risk management infrastructure, policies, procedures, techniques, and processes. As techniques used to perpetrate fraud on our platform evolve, we may need to modify our products or services to mitigate fraud risks. As our business grows and becomes more complex, we may be less able to forecast and carry appropriate reserves in our books for fraud related losses.

Further, these types of fraudulent activities on our platform can also expose us to civil and criminal liability, governmental and regulatory sanctions as well as potentially cause us to be in breach of our contractual obligations to our third-party partners and buyers or suppliers.

Our estimates of market opportunity and forecasts of market growth may prove to be inaccurate, and even if the market in which we compete achieves the forecasted growth, our business could fail to grow at similar rates as we could fail to capture the market share that we anticipate.

Market opportunity estimates and growth forecasts are subject to significant uncertainty and are based on assumptions and estimates that may not prove to be accurate. Our estimates and forecasts relating to the size and expected growth of our market may prove to be inaccurate. Even if the market in which we compete meets our size estimates and forecasted growth, our business could fail to grow at similar rates or we could fail to secure the portion of market share we expect.

43

Our business, which includes payment services, is subject to extensive government regulation and oversight. Our failure to comply with extensive, complex, overlapping, and frequently changing rules, regulations, and legal interpretations could materially harm our business and noncompliance with such laws can subject us to criminal and civil liability.

Financial Services Regulation

In addition to the regulatory regimes described elsewhere, the local, state, and federal laws, rules, regulations, licensing schemes, and industry standards that govern our payment services include, or may in the future include, those relating to banking, invoicing, cross-border and domestic money transmission, foreign exchange, payment processing and settlement services, and escheatment. These laws, rules, regulations, licensing schemes, and industry standards are enforced by multiple authorities and governing bodies in the United States, including federal regulators, self-regulatory organizations, and numerous state and local authorities.

As a licensed money transmitter in various U.S. states and territories, we are subject to a range of restrictions and ongoing compliance obligations under the money transmitter statutes (or their equivalent) administered by the banking departments of the various U.S. states and territories, including requirements with respect to the investment of customer funds, financial recordkeeping and reporting, reconciliation of customer funds, bonding, minimum capital, disclosure, and inspection, audit or examination by regulatory authorities concerning various aspects of our business. In a number of cases, evaluation of our compliance efforts depends on regulatory interpretations that could change over time. In the past, regulators have identified violations or alleged violations of certain statutory and regulatory regimes, and we have been subject to fines, a state consent order and financial penalties by state regulatory authorities due to their interpretation and application of their respective state money transmitter regime to our business model.

In the future, as a result of the financial services regulations applicable to our business, we will be subject to routine examinations by state and federal regulatory authorities; any identified violations or non-compliance during the course of such examinations could subject us to liability, including governmental fines, restrictions on our business, or other similar enforcement actions, and we could be forced to cease conducting certain aspects of our business with residents of certain jurisdictions, be forced to change our business practices in certain jurisdictions, or be required to obtain additional licenses, regulatory approvals, or other similar authorizations. We cannot make any assurances that we will be able to obtain or maintain any such licenses, regulatory approvals, and other similar authorizations, and there could be substantial costs and potential product changes involved in maintaining any such licenses, approvals, or other similar authorizations, which could have a material adverse effect on our business. In addition, there are substantial costs involved in maintaining and renewing those licenses, regulatory approvals, and other similar authorizations that we currently hold, and we could be subject to fines or other enforcement action if we are found to violate the various requirements applicable to us in connection with maintaining the same. These factors could impose substantial additional costs on us, involve considerable delay to the development or provision of our products or services to our customers, require significant and costly operational changes, or prevent us from providing our products or services in any given market.

Governmental authorities may impose new or additional rules on money transmission, including regulations that:

44

Other Regulation

Our success and increased visibility may result in increased regulatory oversight and enforcement and more restrictive rules and regulations that apply to our business. We are subject to a wide variety of local, state and federal laws, rules, regulations, licensing schemes, and industry standards in the United States, which govern numerous areas important to our business; we will likely become subject to additional laws, rules, regulations, licensing schemes, and industry standards in other jurisdictions if we expand our operations internationally in the future. In addition to those laws and regulations described elsewhere, our business is also subject to, without limitation, rules and regulations applicable to: securities, labor and employment, immigration, competition, data usage and marketing and communications practices. These are subject to change, including by means of legislative action and/or executive orders and by way of evolving interpretations and application of existing statutory and regulatory regimes by the applicable regulatory authorities. Thus, it may be difficult to predict how these changes will apply to our business and the way we conduct our operations, particularly as we introduce new products and services and expand into new jurisdictions. We may not be able to respond quickly or effectively to regulatory, legislative, or other developments, which, in turn, may impair our ability to offer our existing or planned features, products, and services and/or increase our cost of doing business.

Although we have a compliance program focused on the laws, rules, regulations, licensing schemes, and industry standards that we have determined apply to our business, and although we continue to prioritize investments in this program, we can make no assurances that our employees or contractors will not violate such laws, rules, regulations, licensing schemes, and industry standards. Any failure or perceived failure to comply with existing or new laws, rules, regulations, licensing schemes, or industry standards (including as a result of any changes to the interpretation or application of the same), may:

The complexity of U.S. federal and state regulatory and enforcement regimes, coupled with the scope of any future international operations and the evolving regulatory environment, could result in a single event giving rise to many overlapping investigations and legal and regulatory proceedings by multiple government authorities in different jurisdictions.

45

Any of the foregoing could, individually or in the aggregate, harm our reputation as a trusted provider, damage our brands and business, cause us to lose existing customers, prevent us from obtaining new customers, require us to expend significant funds to remedy problems caused by violations and to avoid further violations, expose us to legal or regulatory risk and potential liability, and adversely affect our results of operations and financial condition.

We are subject to governmental regulation and other legal obligations related to privacy, data protection, and information security, and our actual or perceived failure to comply with such obligations could harm our business, by resulting in litigation, fines, penalties, or adverse publicity and reputational damage that may negatively affect the value of our business and decrease the value of our common stock. Compliance with such laws could also result in additional costs and liabilities to us or inhibit sales of our products.

Our buyers and other users store personal and business information, financial information and other sensitive information on our platform. In addition, we receive, store, and process personal and business information and other data from and about actual and prospective customers and users, in addition to our employees and service providers. Our handling of data may subject us to a variety of laws and regulations, including regulation by various government agencies. Our data handling also is subject to contractual obligations and industry standards.

The U.S. federal and various state and foreign governments have adopted or proposed limitations on the collection, distribution, use, and storage of data relating to individuals and businesses, including the use of contact information and other data for marketing, advertising, and other communications with individuals and businesses. In the United States, various laws and regulations apply to the collection, processing, disclosure, and security of certain types of data. The laws and regulations relating to privacy and data security are evolving, can be subject to significant change, and may result in ever-increasing regulatory and public scrutiny and escalating levels of enforcement and sanctions. Additionally, the scope and interpretation of the laws that are or may be applicable to us are often uncertain and may be conflicting, as a result of the rapidly evolving regulatory framework for privacy issues worldwide.

Any failure or perceived failure by us to comply with laws, regulations, policies, legal, or contractual obligations, industry standards, or regulatory guidance relating to privacy or data security, may result in governmental investigations and enforcement actions, litigation, fines and penalties, or adverse publicity, and could cause our customers and partners to lose trust in us, which could have an adverse effect on our reputation and business. We expect that there will continue to be new proposed laws, regulations, and industry standards relating to privacy, data protection, marketing, consumer communications, and information security, and we cannot determine the impact such future laws, regulations, and standards may have on our business. Future laws, regulations, standards, and other obligations or any changed interpretation of existing laws or regulations could impair our ability to develop and market new functionality, use particular forms of data, and maintain and grow our customer base and increase revenue. Future restrictions on the collection, use, sharing, or disclosure of data, or additional requirements for express or implied consent of our customers, partners, or end users for the use and disclosure of such information could require us to incur additional costs or modify our platform, possibly in a material manner, and could limit our ability to develop new functionality.

As we expand into new jurisdictions, the number of foreign laws, rules, regulations, licensing schemes, and industry standards governing our business will expand. In addition, as we expand our business and develop new products and services, we may become subject to additional laws, rules, regulations, licensing schemes, and industry standards. We may not always be able to accurately predict the scope or applicability of certain laws, rules, regulations, licensing schemes, or industry standards to our business, particularly as we expand into new areas of operations, which could have a significant negative effect on our existing business and our ability to pursue future plans.

46

We are subject to governmental laws and requirements regarding economic and trade sanctions, export controls, anti-money laundering, and counter-terror financing that could impair our ability to compete in international markets or subject us to criminal or civil liability if we violate them.

Although we currently only operate in the United States, in the future, we may seek to expand internationally. In that case, we would become subject to additional laws and regulations, and would need to implement new controls to comply with applicable laws and regulations. We are required to comply with U.S. export control and economic and trade sanctions administered by the U.S. Department of the Treasury’s Office of Foreign Assets Control, or OFAC. We have implemented policies and procedures designed to ensure compliance with these regulations and requirements, as well as similar requirements in other jurisdictions, to the extent applicable. However, we cannot assure you that such policies and procedures will effectively prevent violations of these laws in the future. If we fail to comply with applicable export control and economic and trade sanctions laws, we could be subject to fines or other enforcement actions, which could adversely affect our business. We are also subject to various anti-money laundering, or AML, and counter-terrorist financing laws and regulations around the world that prohibit, among other things, our involvement in transferring the proceeds of criminal activities. In the United States, most of our services are subject to AML laws and regulations, including the Bank Secrecy Act of 1970, as amended by the USA PATRIOT Act of 2001, and its implementing regulations, or collectively, the BSA, and other similar laws and regulations. The BSA, among other things, requires money transmitters to develop and implement risk-based AML programs, to report large cash transactions and suspicious activity, and, in some cases, to collect and maintain information about customers who use their services and maintain other transaction records. Regulators in the U.S. and globally continue to increase their scrutiny of compliance with these obligations, which may require us to further revise or expand our compliance program, including the procedures we use to verify the identity of our customers and to monitor transactions on our system, including payments to persons outside of the United States Regulators regularly re-examine the transaction volume thresholds at which we must obtain and keep applicable records or verify identities of customers, and any change in such thresholds could result in greater costs for compliance. Regulators and third-party auditors have identified gaps in our AML program, and we could be subject to potentially significant fines, penalties, inquiries, audits, investigations, enforcement actions, and criminal and civil liability if such gaps are not sufficiently remediated or our AML program is found to violate the BSA by a regulator.

We are subject to anti-corruption, anti-bribery, and similar laws, and non-compliance with such laws can subject us to criminal or civil liability and harm our business and reputation.

We are subject to the U.S. Foreign Corrupt Practices Act, or the FCPA, the U.S. domestic bribery statute contained in 18 U.S.C. § 201, the U.S. Travel Act, and other anti-corruption and anti-bribery laws and regulations in any non-U.S. jurisdictions in which we do business. These laws generally prohibit companies, their employees, and their third-party intermediaries from promising, authorizing, making, offering, or providing, directly or indirectly, anything of value to foreign government officials or commercial partners for the purpose of obtaining or retaining business or securing an improper business advantage. These laws also require that we keep accurate books and records and maintain internal controls and compliance procedures designed to prevent any such actions.

As we increase our international business, our risks under these laws may increase. Although we currently only maintain operations in the United States, as we increase our international cross-border business and expand operations abroad, we may engage with business partners and third-party intermediaries to market our services and to obtain necessary permits, licenses, and other regulatory approvals. In addition, we or our third-party intermediaries may have direct or indirect interactions with officials and employees of government agencies or state-owned or affiliated entities. We can be held liable for the corrupt or other illegal activities of these third-party intermediaries, our employees, representatives, contractors, partners, and agents, even if we do not explicitly authorize such activities; and we cannot assure that all of our employees and agents will comply with applicable anti-corruption and anti-bribery laws and internal policies.

47

Detecting, investigating, and resolving actual or alleged violations of anti-corruption laws can require a significant diversion of time, resources, and attention from senior management. In addition, noncompliance with anti- corruption or anti-bribery laws could subject us to whistleblower complaints, investigations, sanctions, settlements, prosecution, enforcement actions, fines, damages, other civil or criminal penalties, injunctions, suspension or debarment from contracting with certain persons, reputational harm, adverse media coverage, and other collateral consequences. If any subpoenas are received or investigations are launched, or governmental or other sanctions are imposed, or if we do not prevail in any possible civil or criminal proceeding, our business, results of operations, financial condition, and growth prospects could be materially harmed. In addition, responding to any action will likely result in a materially significant diversion of management’s attention and resources and significant defense costs and other professional fees.

Indemnity provisions in various agreements potentially expose us to substantial liability for intellectual property infringement, data protection, and other losses.

Our agreements with partners and certain customers may include indemnification provisions under which we agree to indemnify them for losses suffered or incurred as a result of claims of intellectual property infringement, data protection, damages caused by us to property or persons, or other liabilities relating to or arising from our platform or other contractual obligations. Some of these indemnity agreements provide for uncapped liability and some indemnity provisions survive termination or expiration of the applicable agreement. Large indemnity payments could harm our business, operating results, and financial condition. Although we normally limit our liability with respect to such obligations in our contracts with direct customers and with customers acquired through our accounting firm partners, we may still incur substantial liability, and we may be required to cease use of certain functions of our platform or products, as a result of IP-related claims. Any dispute with a customer with respect to these obligations could have adverse effects on our relationship with that customer and other existing or new customers, and harm our business and operating results. In addition, although we carry insurance, our insurance may not be adequate to indemnify us for all liability that may be imposed, or otherwise protect us from liabilities or damages with respect to claims alleging compromises of customer data, and any such coverage may not continue to be available to us on acceptable terms or at all.

We could be required to collect additional sales taxes or be subject to other tax liabilities that may increase the costs our customers would have to pay for our offerings and adversely affect our operating results.

The vast majority of states have considered or adopted laws that impose tax collection obligations on out-of-state companies. States where we have nexus may require us to calculate, collect, and remit taxes on sales in their jurisdiction. Additionally, the Supreme Court of the U.S. ruled in South Dakota v. Wayfair, Inc. et al (Wayfair) that online sellers can be required to collect sales and use tax despite not having a physical presence in the buyer’s state. In response to Wayfair, or otherwise, states or local governments may enforce laws requiring us to calculate, collect, and remit taxes on sales in their jurisdictions. We may be obligated to collect and remit sales and use tax in states in which we have not historically collected and remitted sales and use tax. A successful assertion by one or more states requiring us to collect taxes where we historically have not or presently do not do so could result in substantial tax liabilities, including taxes on past sales, as well as penalties and interest. The imposition by state governments or local governments of sales tax collection obligations on out-of-state sellers could also create additional administrative burdens for us, put us at a perceived competitive disadvantage if they do not impose similar obligations on our competitors, and decrease our future sales, which could adversely affect our business and operating results.

Our ability to use our net operating losses, or NOLs, to offset future taxable income may be subject to certain limitations.

As of December 31, 2020, we had federal and state NOL carryforwards of approximately $338.8 million and $314.8 million, respectively. The federal NOLs include $141.6 million that may be used to offset up to 100% of future taxable income and the federal and state NOLs will begin to expire in the calendar year 2021, unless

48

previously utilized. The NOL carryforwards subject to expiration could expire unused and be unavailable to offset future income tax liabilities.

Under the Tax Cuts and Jobs Act, or the Tax Act, as modified by the Coronavirus Aid, Relief and Economic Security Act, or CARES Act, federal NOLs incurred in taxable years beginning after December 31, 2017 may be carried forward indefinitely, but the deductibility of such federal NOLs in taxable years beginning after December 31, 2020 is limited to 80% of taxable income in such years. There is variation in how states have responded and may continue to respond to the Tax Act and CARES Act.

Separately, under Section 382 of the Internal Revenue Code of 1986, as amended, or the Code, and corresponding provisions of state law, if a corporation undergoes an “ownership change,” which is generally defined as a greater than 50% change, by value, in its equity ownership over a three-year period, the corporation’s ability to use its pre-change NOL carryforwards and other pre-change tax attributes to offset its post-change income or taxes may be limited. Similar rules may apply under state tax laws. We may have experienced such ownership changes in the past, and we may experience ownership changes in the future as a result of this offering or subsequent shifts in our stock ownership, some of which are outside our control. We have not conducted any studies to determine if our NOLs could be subject to limitation as a result of such changes in ownership. For these reasons, our ability to utilize our NOL carryforwards and other tax attributes to reduce future tax liabilities may be limited, which would have a material adverse effect on our cash flows and results of operations.

Changes in our effective tax rate or tax liability may adversely affect our operating results.

Our effective tax rate could increase due to several factors, including:

Any of these developments could adversely affect our operating results.

Any future litigation against us could be costly and time consuming to defend.

We may become subject to legal proceedings and claims that arise in the ordinary course of business, such as claims brought in connection with intellectual property disputes, claims brought by our customers in connection with commercial disputes, employment claims made by our current or former employees, or claims for reimbursement following misappropriation of customer funds or data.

The software industry is characterized by the existence of many patents, copyrights, trademarks, trade secrets, and other intellectual and proprietary rights. Companies in the software industry are often required to defend against litigation claims based on allegations of infringement or other violations of intellectual property rights. Our technologies may not be able to withstand any third-party claims against their use. In addition, many companies have the capability to dedicate substantially greater resources to enforce their intellectual property rights and to defend claims that may be brought against them. If a third party is able to obtain an injunction preventing us from accessing such third-party intellectual property rights, or if we cannot license or develop alternative technology for any infringing aspect of our business, we would be forced to limit or stop sales of our

49

software or cease business activities related to such intellectual property. Any inability to license third-party technology in the future would have an adverse effect on our business or operating results and would adversely affect our ability to compete. We may also be contractually obligated to indemnify our customers in the event of infringement of a third party’s intellectual property rights.

Lawsuits are time-consuming and expensive to resolve and they divert management’s time and attention. Although we carry insurance, our insurance may not cover certain future claims, may not provide sufficient payments to cover all the costs to resolve one or more such claims, and might not continue to be available on terms acceptable to us. A claim brought against us that is uninsured or underinsured could result in unanticipated costs, thereby reducing our operating results and leading analysts or potential investors to reduce their expectations of our performance, which could reduce the trading price of our stock.

We cannot predict the outcome of lawsuits and cannot assure you that the results of any such actions will not have an adverse effect on our business, operating results, or financial condition.

Our Senior Secured Credit Facilities and Guaranty Agreement provides our lenders with a first-priority lien against substantially all of our and our subsidiaries’ assets and personal property, and contains financial covenants and other restrictions on our and our subsidiaries’ actions, which could limit our operational flexibility and otherwise adversely affect our financial condition.

Our Senior Secured Credit Facilities and Guaranty Agreement, or our Senior Facilities Agreement, restricts our and our subsidiaries’ ability to, among other things (in each case, subject to certain exceptions based on dollar caps or other conditions):

50

Our Senior Facilities Agreement also contains certain financial covenants that prohibit us from (i) allowing our and our subsidiaries’ ratio of total debt to recurring revenue (i.e., our Consolidated Recurring Revenue Ratio, as defined in the Senior Facilities Agreement) as of the end of each fiscal quarter to be in excess of prescribed maximums, (ii) allowing our and our subsidiaries’ balance of unrestricted cash-on-hand in the United States less our usage of the revolving credit and letter of credit capacity under our Senior Facilities Agreement to be less than the prescribed minimum and (iii) allowing our and our subsidiaries’ segregated cash and cash equivalents balance required to be maintained pursuant to applicable financial services laws (i.e., our Client Funds Coverage Amount, as defined in the Senior Facilities Agreement) to be in excess of the prescribed maximums under a prescribed formula. Our ability to comply with these and other covenants is dependent upon several factors, some of which are beyond our control.

Our or our subsidiaries’ failure to comply with the covenants or payment requirements, or the occurrence of other events specified in our Senior Facilities Agreement, could result in an event of default under the Senior Facilities Agreement, which would give our lenders, in addition to other rights and remedies, the right to terminate their commitments to provide additional loans under the Senior Facilities Agreement and to declare all outstanding loans, together with accrued and unpaid interest and fees and any other outstanding amounts, to be immediately due and payable. In addition, we and our subsidiaries have granted our lenders under the Senior Facilities Agreement first-priority liens against substantially all of our and our subsidiaries’ assets and property as collateral. If the debt under our Senior Facilities Agreement was to be accelerated, we might not have sufficient cash on hand or be able to sell sufficient collateral to repay the obligations then due. In such event, the lenders under our Senior Facilities Agreement would have the right to, among other remedies, enforce liens against our and our subsidiaries assets and property and seek other judicial and non-judicial enforcement of their rights, any or all of which would likely have an immediate adverse effect on our business and operating results.

If we are unable to effectively document or perfect our ownership over our proprietary technology and intellectual property, our ability to protect our proprietary rights against third parties might be adversely affected.

Historically, we have developed our proprietary technology and other intellectual property both internally, through development by our employees and consultants, and externally, through engaging third party developers in the United States and abroad. We generally enter into confidentiality and invention assignment agreements with such employees, consultants and third party developers with the expressed intention that we own all proprietary rights in all applicable technology and intellectual property developed during the relationship. However, it is possible that these agreements may not have been properly entered into on every occasion with the applicable counterparty, and if one of these agreements were found to be defective under applicable law, it may not have effectively granted ownership of certain technology or other intellectual property to us. In such an event, there would be a risk that the applicable counterparty would not be available to (or would not be willing to) assist us in perfecting our ownership of the technology or intellectual property, which may have an adverse effect on our ability to protect our proprietary rights over such technology and intellectual property.

If we are unable to obtain necessary or desirable third-party technology licenses, our ability to develop platform enhancements may be impaired.

We utilize commercially available off-the-shelf technology in the development of our products and services. As we continue to introduce new features or improvements to our products and services, we may be required to

51

license additional technologies from third parties. These third-party licenses may be unavailable to us on commercially reasonable terms, if at all. If we are unable to obtain necessary third-party licenses, we may be required to obtain substitute technologies with lower quality or performance standards, or at a greater cost, any of which could harm the competitiveness of our platform and our business. In the future, we could be required to seek licenses from third parties in order to continue offering our products and services or to develop enhancements to our technology, which licenses may not be available on terms that are acceptable to us, or at all. Our inability to use third-party software could result in disruptions to our business, or delays in the development of future offerings or enhancements of existing offerings, which could impair our business, financial condition, and results of operations.

We use open-source software in our products, which could subject us to litigation or other actions.

We use open-source software in the development of our products and services. From time to time, there have been claims challenging the ownership of open-source software against companies that incorporate it into their products. As a result, we could be subject to lawsuits by parties claiming ownership of what we believe to be open-source software. Litigation could be costly for us to defend, have a negative effect on our operating results and financial condition, or require us to devote additional research and development resources to change our products. In addition, if we were to combine our proprietary software products with open-source software in a certain manner under certain open-source licenses, we could be required to release the source code of our proprietary software products. If we inappropriately use or incorporate open-source software subject to certain types of open-source licenses that challenge the proprietary nature of our products, we may be required to re-engineer such products, discontinue the sale of such products, or take other remedial actions.

If our technology and other proprietary rights are not adequately protected to prevent use or appropriation by our competitors, the value of our brand and other intangible assets may be diminished, and our business may be adversely affected.

We rely and expect to continue to rely on a combination of confidentiality and license agreements with our employees, consultants and third parties with whom we have relationships, as well as trademark, copyright, patent and trade secret protection laws, to protect our proprietary rights. We may also seek to enforce our proprietary rights through court proceedings or other legal actions. We have filed and we expect to file from time to time for trademark, copyright and patent applications. However, the steps we take to protect our intellectual property rights may be inadequate. We make business decisions about when to seek patent protection for a particular technology and when to rely upon trade secret protection, and the approach we select may ultimately prove to be inadequate. For example, we have not historically prioritized seeking patent protections for our technology and therefore we may have limited capacity to assert proprietary rights against third parties that may offer similar products, services or functionality. Even in cases where we seek patent protection, we cannot assure that the resulting patents will effectively protect every significant feature of our solutions and any U.S. or other patents issued to us may not be sufficiently broad to protect our proprietary technologies. Specifically, there can be no guarantee that others will not independently develop similar products, duplicate any of our solutions or design around our patents, or adopt similar or identical brands for competing platforms or technology. Furthermore, legal standards relating to the validity, enforceability and scope of protection of intellectual property rights are uncertain. Therefore, our registration applications may not be approved, third parties may challenge any copyrights, patents or trademarks issued to or held by us, third parties may knowingly or unknowingly infringe our intellectual property rights, and we may not be able to prevent infringement or misappropriation without substantial expense to us. If the protection of our intellectual property rights is inadequate to prevent use or misappropriation by third parties, the value of our brand, content, and other intangible assets may be diminished.

Further, intellectual property law, including statutory and case law, particularly in the United States, is constantly developing, and any changes in the law could make it harder for us to enforce our rights. In addition, we believe that the protection of our trademark rights is an important factor in product recognition, protecting our brand and

52

maintaining goodwill. If we do not adequately protect our rights in our trademarks from infringement and unauthorized use, any goodwill that we have developed in those trademarks could be lost or impaired, which could harm our brand and our business. Failure to protect our domain names could also adversely affect our reputation and brand and make it more difficult for subscribers to find our products and services. We may be unable, without significant cost or at all, to prevent third parties from acquiring domain names that are similar to, infringe upon or otherwise decrease the value of our trademarks and other proprietary rights.

We enter into confidentiality and invention assignment agreements with our employees and consultants and enter into confidentiality agreements with the parties with whom we have strategic relationships and business alliances. No assurance can be given that these agreements will be effective in controlling access to and distribution of our proprietary information. Further, these agreements do not prevent our competitors or partners from independently developing technologies that are substantially equivalent or superior to our platform.

In order to protect our intellectual property rights, we may be required to spend significant resources to monitor and protect these rights. Litigation may be necessary in the future to enforce our intellectual property rights and to protect our intellectual property. Litigation brought to protect and enforce our intellectual property rights could be costly, time-consuming and distracting to management and could result in the impairment or loss of portions of our intellectual property. Furthermore, our efforts to enforce our intellectual property rights may be met with defenses, counterclaims and countersuits attacking the validity and enforceability of our intellectual property rights. An adverse determination of any litigation proceedings could put our intellectual property at risk of being invalidated or interpreted narrowly and could put our related patents, patent applications and trademark filings at risk of not issuing or being cancelled. Furthermore, because of the substantial amount of discovery required in connection with intellectual property litigation, there is a risk that some of our confidential or sensitive information could be compromised by disclosure in the event of litigation. Our inability to protect our proprietary technology against unauthorized copying or use, as well as any costly litigation or diversion of our management’s attention and resources, could delay further sales or the implementation of our platform, impair the functionality of our platform, delay introductions of new functionality to our platform, result in our substituting inferior or more costly technologies into our platform, or injure our reputation. We will not be able to protect our intellectual property if we are unable to enforce our rights or if we do not detect unauthorized use of our intellectual property. Moreover, policing unauthorized use of our technologies, trade secrets and intellectual property may be difficult, expensive and time-consuming, particularly in foreign countries where the laws may not be as protective of intellectual property rights as those in the United States and where mechanisms for enforcement of intellectual property rights may be weak. If we fail to meaningfully protect our intellectual property and proprietary rights, our business, operating results and financial condition could be adversely affected.

Accordingly, we may not be able to prevent third parties from infringing upon or misappropriating our intellectual property. Our failure to secure, protect and enforce our intellectual property rights could seriously damage our brand and our business.

Risks Related to Our Initial Public Offering and Ownership of Our Common Stock

The market price of our common stock may be volatile or may decline steeply or suddenly regardless of our operating performance and we may not be able to meet investor or analyst expectations. You may not be able to resell your shares at or above the initial public offering price and may lose all or part of your investment.

The initial public offering price for our common stock will be determined through negotiations between the underwriters and us, and will vary from the market price of our common stock following this offering. If you purchase shares of our common stock in this offering, you may not be able to resell those shares at or above the initial public offering price. We cannot assure you that the market price following this offering will equal or exceed prices in privately negotiated transactions of our shares that have occurred from time to time before this offering. The market price of our common stock may fluctuate or decline significantly in response to numerous factors, many of which are beyond our control, including:

In addition, extreme price and volume fluctuations in the stock markets have affected and continue to affect many technology companies’ stock prices. Stock prices often fluctuate in ways unrelated or disproportionate to a company’s operating performance. In the past, stockholders have filed securities class action litigation following periods of market volatility. If we were to become involved in securities litigation, it could subject us to substantial costs, divert resources and the attention of management from our business and seriously harm our business.

Moreover, because of these fluctuations, comparing our operating results on a period-to-period basis may not be meaningful. You should not rely on our past results as an indication of our future performance. This variability and unpredictability could also result in our failing to meet the expectations of industry or financial analysts or investors for any period. If our revenues or operating results fall below the expectations of analysts or investors or below any forecasts we may provide to the market, or if the forecasts we provide to the market are below the

54

expectations of analysts or investors, the price of our common stock could decline substantially. Such a stock price decline could occur even when we have met any previously publicly stated revenue or earnings forecasts that we may provide.

Sales of a substantial number of shares of our common stock in the public market, or the perception that they might occur, could cause the price of our common stock to decline.

The price of our common stock could decline if there are substantial sales of our common stock, particularly sales by our directors, executive officers, and significant stockholders. We had a total of 13,650,953 shares of our common stock outstanding as of June 30, 2021. Our executive officers, directors, and other stockholders and optionholders owning substantially all of our common stock and options to acquire common stock will be subject to a lock-up agreement with respect to their shares. These agreements contain several exemptions from the lock-up restrictions. For example, our executive officers may enter into Rule 10b5-1 trading plans under which they would contract with a broker to sell shares of our common stock on a periodic basis. These plans provide for sales to occur from time to time, and sales under such plans that were entered into prior to execution of a lock-up agreement in connection with this offering by our executive officers will not be subject to the additional lock-up period related to this offering.

Sales of a substantial number of shares of our common stock in the public market, or the perception that these sales might occur, whether due to the expiration or release of lock-up restrictions or otherwise, could cause the market price of our common stock to decline or make it more difficult for you to sell your common stock at a time and price that you deem appropriate and could impair our ability to raise capital through the sale of additional equity securities. We are unable to predict the effect that sales, or the perception that our shares may be available for sale, will have on the prevailing market price of our common stock.

Certain of our stockholders have rights, subject to some conditions, to require us to file registration statements covering their shares and/or to include their shares in registration statements that we may file for ourselves or our stockholders, subject to market standoff and lockup agreements. The market price of the shares of our common stock could decline as a result of the sale of a substantial number of our shares of common stock in the public market or the perception in the market that the holders of a large number of shares intend to sell their shares.

In addition, we intend to file registration statements to register shares reserved for future issuance under our equity compensation plans. Subject to the satisfaction of applicable exercise periods and expiration of the lock-up agreements referred to above, the shares issued upon exercise of outstanding stock options or settlement of outstanding RSUs will be available for immediate resale in the United States in the open market.

We may require additional capital to support the growth of our business, and this capital might not be available on acceptable terms, if at all.

We have funded our operations to date primarily through equity financings, sales of our products and services, and transaction fees. We cannot be certain when or if our operations will generate sufficient cash to fully fund our ongoing operations or the growth of our business. Additionally, we expect to continue to invest heavily in our business and expend substantial financial and other resources on:

55

These investments may not result in increased revenue growth in our business. If we are unable to increase our revenue at a rate sufficient to offset the expected increase in our costs, or if we encounter difficulties in managing a growing volume of payments, we may be required to engage in equity or debt financings to secure additional capital, which may be dilutive to our current stockholders. Additional financing may not be available on terms favorable to us, if at all. If adequate funds are not available on acceptable terms, we may be unable to invest in future growth opportunities, which could harm our business, operating results, and financial condition. Because our decision to issue securities in the future will depend on numerous considerations, including certain factors beyond our control, we cannot predict or estimate the amount, timing, or nature of any future issuances of debt or equity securities. As a result, our stockholders bear the risk of future issuances of debt or equity securities reducing the value of our current stock and diluting their interests.

If securities or industry analysts either do not publish research about us or publish inaccurate or unfavorable research about us, our business or our market, or if they change their recommendations regarding our common stock adversely, the trading price or trading volume of our common stock could decline.

The trading market for our common stock will be influenced in part by the research and reports that securities or industry analysts may publish about us, our business, our market or our competitors. If one or more analysts initiate research with an unfavorable rating or downgrade our common stock, provide a more favorable recommendation about our competitors or publish inaccurate or unfavorable research about our business, our common stock price would likely decline. If any analyst who may cover us were to cease coverage of us or fail to regularly publish reports on us, we could lose visibility in the financial markets, which in turn could cause the trading price or trading volume of our common stock to decline.

We do not intend to pay dividends for the foreseeable future and, as a result, your ability to achieve a return on your investment will depend on appreciation in the price of our common stock.

We have never declared or paid any cash dividends on our capital stock, and we do not intend to pay any cash dividends in the foreseeable future. In addition, our Senior Credit Facilities Agreement contains restrictions on our ability to pay cash dividends on our capital stock. Any determination to pay dividends in the future will be at the discretion of our board of directors. Accordingly, investors must rely on sales of their common stock after price appreciation, which may never occur, as the only way to realize any future gains on their investments.

Delaware law and provisions in our amended and restated certificate of incorporation and bylaws that will be in effect immediately following the completion of this offering could make a merger, tender offer or proxy contest difficult, thereby depressing the trading price of our common stock.

Our amended and restated certificate of incorporation and bylaws that will go into effect immediately following the completion of this offering contain provisions that could depress the trading price of our common stock by acting to discourage, delay or prevent a change of control of our company or changes in our management that the stockholders of our company may deem advantageous. For example, these provisions:

56

Any provision of our amended and restated certificate of incorporation or bylaws that will be in effect immediately following the completion of this offering or Delaware law that has the effect of delaying or deterring a change in control could limit the opportunity for our stockholders to receive a premium for their shares of our common stock, and could also affect the price that some investors are willing to pay for our common stock. For information regarding these and other provisions, see section titled “Description of Capital Stock — Anti-Takeover Provisions.”

Our amended and restated certificate of incorporation, to be effective immediately following the closing of this offering, will provide that the Court of Chancery of the State of Delaware (or, if and only if the Court of Chancery of the State of Delaware lacks subject matter jurisdiction, any state court located within the State of Delaware or, if and only if all such state courts lack subject matter jurisdiction, the federal district court for the District of Delaware) is the sole and exclusive forum for the following types of actions or proceedings under Delaware statutory or common law: (i) any derivative action or proceeding brought on our behalf; (ii) any action or proceeding asserting a claim of breach of a fiduciary duty owed by any of our current or former directors, officers, or other employees or stockholders to us or our stockholders, or any action asserting a claim for aiding and abetting such breach of fiduciary duty; (iii) any action or proceeding asserting a claim against us or any of our current or former directors, officers or other employees arising out of or pursuant to any provision of the Delaware General Corporation Law, or DGCL, our amended and restated certificate of incorporation or our amended and restated bylaws; (iv) any action or proceeding to interpret, apply, enforce or determine the validity of our amended and restated certificate of incorporation or our amended and restated bylaws (including any right, obligation, or remedy thereunder); (v) any action or proceeding as to which the DGCL confers jurisdiction to the Court of Chancery of the State of Delaware; and (vi) any action or proceeding asserting a claim against us or any of our current or former directors, officers, or other employees or stockholders that is governed by the internal affairs doctrine, in all cases to the fullest extent permitted by law and subject to the court’s having personal jurisdiction over the indispensable parties named as defendants. This provision would not apply to suits brought to enforce a duty or liability created by the Securities Exchange Act of 1934, as amended, or the Exchange Act, or any other claim for which the federal courts have exclusive jurisdiction. In addition, to prevent having to litigate claims in multiple jurisdictions and the threat of inconsistent or contrary rulings by different courts, among other considerations, our amended and restated certificate of incorporation to be effective immediately following the closing of this offering will provide that, unless we consent in writing to the selection of an alternative forum, to the fullest extent permitted by law, the federal district courts of the United States will be the exclusive forum for resolving any complaint asserting a cause of action arising under the Securities Act of 1933, as amended, or the Securities Act, including all causes of action asserted against any defendant named in such complaint. For the avoidance of doubt, this provision is intended to benefit and may be enforced by us, our officers and directors, the underwriters to any offering giving rise to such complaint, and any other professional entity whose profession gives authority to a statement made by that person or entity and who has prepared or certified any part of the documents underlying the offering. However, as Section 22 of the Securities Act creates concurrent jurisdiction for federal and state courts over all suits brought to enforce any duty or liability created by the Securities Act or the rules and regulations thereunder, there is uncertainty as to whether a court would enforce such provision. Our amended and restated certificate of incorporation, to be effective immediately following the closing of this offering,

57

will further provide that any person or entity holding, owning or otherwise acquiring any interest in any of our securities shall be deemed to have notice of and consented to these provisions. Investors also cannot waive compliance with the federal securities laws and the rules and regulations thereunder.

These choice of forum provisions may limit a stockholder’s ability to bring a claim in a judicial forum that it finds favorable for disputes with us or our directors, officers, or other employees. While the Delaware courts have determined that such choice of forum provisions are facially valid, a stockholder may nevertheless seek to bring such a claim arising under the Securities Act against us, our directors, officers, or other employees in a venue other than in the federal district courts of the United States. In such instance, we would expect to vigorously assert the validity and enforceability of the exclusive forum provisions of our amended and restated certificate of incorporation. This may require significant additional costs associated with resolving such action in other jurisdictions and we cannot assure you that the provisions will be enforced by a court in those other jurisdictions. If a court were to find either exclusive-forum provision in our amended and restated certificate of incorporation to be inapplicable or unenforceable in an action, we may incur further significant additional costs associated with resolving the dispute in other jurisdictions, all of which could harm our business.

We have broad discretion in how we may use the net proceeds from this offering, and we may not use them effectively.

The principal purposes of this offering are to create a public market for our common stock, facilitate access to the public equity markets, increase our visibility in the marketplace and obtain additional capital to support further growth in our business. Our management will have broad discretion in applying the net proceeds we receive from this offering. We may use the net proceeds (including any additional proceeds that we may receive if the underwriters exercise their option to purchase additional shares of our common stock) to redeem the shares of redeemable preferred stock issuable upon conversion of our senior preferred stock (approximately $169 million), and for general corporate purposes, which we currently expect will include head count expansion, continued investment in our sales and marketing efforts, product development, general and administrative matters, and working capital. We may also use a portion of the net proceeds for acquisitions or strategic investments in complementary businesses, products, services or technologies, although we do not currently have any definitive plans or commitments for any such acquisitions or investments. We may also spend or invest these proceeds in a way with which our stockholders disagree. If our management fails to use these funds effectively, our business could be seriously harmed.

We are an emerging growth company, and any decision on our part to comply only with certain reduced reporting and disclosure requirements applicable to emerging growth companies could make our common stock less attractive to investors.

We are an emerging growth company and, for as long as we continue to be an emerging growth company, we may choose to take advantage of exemptions from various reporting requirements applicable to other public companies but not to “emerging growth companies,” including:

As a result, our stockholders may not have access to certain information they may deem important. We could be an emerging growth company for up to five years, although circumstances could cause us to lose that status earlier, including if our total annual gross revenues exceed $1.07 billion, if we issue more than $1.0 billion in non-convertible debt securities during any three-year period, or if we are a large accelerated filer and the market

58

value of our common stock held by non-affiliates exceeds $700 million as of the end of any second quarter before that time. We cannot predict if investors will find our common stock less attractive if we choose to rely on any of the exemptions afforded emerging growth companies. If some investors find our common stock less attractive because we rely on any of these exemptions, there may be a less active trading market for our common stock and the market price of our common stock may be more volatile.

Under the JOBS Act, “emerging growth companies” can also delay adopting new or revised accounting standards until such time as those standards apply to private companies. We elected to use the extended transition period for complying with new or revised accounting standards that have different effective dates for public and private companies until the earlier of the date that we (1) are no longer an emerging growth company or (2) affirmatively and irrevocably opt out of the extended transition period provided in the JOBS Act. As a result, these financial statements may not be comparable to companies that comply with the new or revised accounting pronouncements as of public company effective dates.

As a result of becoming a public company, we will be obligated to develop and maintain effective internal control over financial reporting, and if we fail to develop and maintain effective disclosure controls and procedures and internal control over financial reporting, our ability to produce timely and accurate financial statements or comply with applicable laws and regulations could be impaired.

Upon becoming a public company, we will be required to comply with the SEC’s rules including implementing effective processes and internal control over financial reporting to comply with the Sarbanes-Oxley Act, the Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010, the listing requirements of the Nasdaq Stock Market and other applicable securities rules and regulations. Compliance with these rules and regulations will increase our legal and financial compliance costs, make some activities more difficult, time consuming, or costly, and increase demand on our systems and resources, particularly after we are no longer an emerging growth company. The Exchange Act requires, among other things, that we file annual, quarterly, and current reports with respect to our business and operating results. The Sarbanes-Oxley Act requires, among other things, that we maintain effective disclosure controls and procedures and internal control over financial reporting.

Compliance with these requirements may require significant resources and management oversight to maintain and, if necessary, improve our disclosure controls and procedures and internal control over financial reporting to meet this standard. As a result, management’s attention may be diverted from other business concerns, which could adversely affect our business and operating results. Although we have already hired additional employees to comply with these requirements, we may need to hire more employees in the future or engage outside consultants, which would increase our costs and expenses.

We will also be required, pursuant to Section 404, to furnish a report by management on, among other things, the effectiveness of our internal control over financial reporting commencing with our second annual report on Form 10-K. Effective internal control over financial reporting is necessary for us to provide reliable financial reports and, together with adequate disclosure controls and procedures, are designed to prevent material misstatements due to fraud or error. Any failure to implement required new or improved controls, or difficulties encountered in their implementation, could cause us to fail to meet our reporting obligations. Ineffective internal controls could also cause investors to lose confidence in our reported financial information, which could have a negative effect on the trading price of our common stock.

This assessment will need to include disclosure of any material weaknesses identified by our management in our internal control over financial reporting, as well as a statement that our independent registered public accounting firm has issued an opinion on the effectiveness of our internal control over financial reporting, provided that our independent registered public accounting firm will not be required to attest to the effectiveness of our internal control over financial reporting until our first annual report required to be filed with the SEC following the later of the date we are deemed to be an “accelerated filer” or a “large accelerated filer,” each as defined in the Exchange Act, or the date we are no longer an emerging growth company, as defined in the JOBS Act. We could

59

be an emerging growth company for up to five years. An independent assessment of the effectiveness of our internal controls could detect problems that our management’s assessment might not. Undetected material weaknesses in our internal control over financial reporting could lead to financial statement restatements and require us to incur the expense of remediation. We will be required to disclose material changes made in our internal control over financial reporting on a quarterly basis. To comply with the requirements of being a public company, we may need to undertake various actions, such as implementing new internal controls and procedures and hiring additional accounting or internal audit staff.

We have already made significant progress towards the challenging process of compiling the system and processing documentation necessary to perform the evaluation needed to comply with Section 404. We may not be able to complete our evaluation, testing, and any required remediation in a timely fashion. During the evaluation and testing process, if we identify material weaknesses in our internal control over financial reporting, we will be unable to assert that our internal control over financial reporting is effective.

If we are unable to assert that our internal control over financial reporting is effective, or if our independent registered public accounting firm is unable to express an unqualified opinion on the effectiveness of our internal control, including as a result of the material weaknesses described above, we could lose investor confidence in the accuracy and completeness of our financial reports, which could cause the price of our common stock to decline, and we may be subject to investigation or sanctions by the SEC. In addition, if we are unable to continue to meet these requirements, we may not be able to remain listed on the Nasdaq exchange.

Our management team has limited experience managing a public company.

Our management team has limited experience managing a publicly traded company, interacting with public company investors and securities analysts, and complying with the increasingly complex laws pertaining to public companies. These new obligations and constituents require significant attention from our management team and could divert their attention away from the day-to-day management of our business, which could harm our business, operating results, and financial condition.

An active trading market for our common stock may never develop or be sustained.

We have applied to list our common stock on Nasdaq under the symbol “AVDX.” However, we cannot assure you that an active trading market for our common stock will develop on that exchange or elsewhere or, if developed, that any market will be sustained. Accordingly, we cannot assure you of the likelihood that an active trading market for our common stock will develop or be maintained, the liquidity of any trading market, your ability to sell your shares of our common stock when desired or at the prices that you may obtain for your shares.

If you purchase our common stock in this offering, you will incur immediate and substantial dilution.

The assumed initial public offering price is substantially higher than the net tangible book value per share of our common stock of $             per share as of             . Investors purchasing common stock in this offering will pay a price per share that substantially exceeds the book value of our tangible assets after subtracting our liabilities, goodwill, intangible assets and redeemable non-controlling interest. As a result, investors purchasing common stock in this offering will incur immediate dilution of $             per share, at the initial public offering price of $             per share. This dilution is due to the substantially lower price paid by our investors who purchased shares prior to this offering as compared to the price offered to the public in this offering.

You will be diluted by the future issuance of common stock, preferred stock or securities convertible into common or preferred stock, in connection with our incentive plans, acquisitions, capital raises or otherwise.

After this offering, we will have outstanding              shares of common stock. Our amended and restated certificate of incorporation, which will become effective prior to the closing of this offering, authorizes us to

60

issue shares of common stock and options, rights, warrants, and appreciation rights relating to common stock for the consideration and on the terms and conditions established by our board of directors in its sole discretion, whether in connection with acquisitions or otherwise.

In the future, we expect to obtain financing or to further increase our capital resources by issuing additional shares of our capital stock or offering debt or other equity securities, including senior or subordinated notes, or debt securities convertible into equity or shares of preferred stock. Issuing additional shares of our capital stock or other equity securities or securities convertible into equity may dilute the economic and voting rights of our existing stockholders or reduce the market price of our common stock or both. Debt securities convertible into equity could be subject to adjustments in the conversion ratio pursuant to which certain events may increase the number of equity securities issuable upon conversion. Shares of preferred stock, if issued, could have a preference with respect to liquidating distributions or a preference with respect to dividend payments that could limit our ability to pay dividends to the holders of our common stock. Our decision to issue securities in any future offering will depend on market conditions and other factors beyond our control, which may adversely affect the amount, timing, or nature of our future offerings. As a result, holders of our common stock bear the risk that our future offerings may reduce the market price of our common stock and dilute their stockholdings in us. See “Description of Capital Stock.”

We have reserved 2,502,017 shares of common stock for issuance under our 2020 Plan, which amount is increased by shares subject to an award under our 2010 Plan or 2017 Plan that expire, are forfeited, or otherwise terminate, or are settled in cash. Any common stock that we issue, including under our 2010 Plan, 2017 Plan and 2020 Plan or other equity incentive plans that we may adopt in the future, would dilute the percentage ownership held by the investors who purchase common stock in this offering. We intend to file one or more registration statements on Form S-8 under the Securities Act, to register shares of our common stock or securities convertible into or exchangeable for shares of our common stock issued pursuant to our 2010 Plan, 2017 Plan or 2020 Plan as well as our new 2021 Plan and ESPP. Any such Form S-8 registration statements will automatically become effective upon filing. Accordingly, shares registered under such registration statements will be available for sale in the open market.
