Organization, Consolidation and Presentation of Financial Statements [Abstract]
Organization and Description of Business	1. Organization and Description of Business Description of Business Paymentus Holdings, Inc. and its wholly owned subsidiaries (“Paymentus” or the "Company”) provides electronic bill presentment and payment services, enterprise customer communication and self-service revenue management to billers through a Software-as-a-Service, (“SaaS”), secure, omni-channel technology platform. The platform seamlessly integrates into a biller’s core financial and operating systems to provide flexible and secure access to payment processing of credit cards, debit cards, eChecks and digital wallets across a significant number of channels including online, mobile, IVR, call center, chatbot and voice-based assistants. Paymentus was incorporated in the state of Delaware on September 2, 2011 with office locations in Charlotte, North Carolina, Richmond Hill, Ontario (Canada), Blacksburg, Virginia, Cromwell, Connecticut, Redmond, Washington and Delhi and Bangalore (India). The Company was headquartered in Charlotte, North Carolina until 2020 when the Company moved its headquarters to Redmond, Washington. Initial Public Offering and Private Placement In May 2021, the Company completed its initial public offering (“IPO”), in which the Company issued and sold 11,500,000 shares of its Class A common stock at $ 21.00 per share, including 1,500,000 shares issued upon the exercise of the underwriters’ option to purchase additional shares. The Company received net proceeds of $ 224.6 million after deducting underwriting discounts and commissions of $ 16.9 million. The Company incurred direct offering expenses of $ 2.0 million. In connection with the IPO: • all 103,479,239 shares of the Company’s outstanding common stock automatically converted into an equivalent number of shares of Class B common stock on a one-to-one basis; and • entities affiliated with Accel-KKR purchased 2,380,950 shares of the Company’s Class A common stock at $ 21.00 per share in a concurrent private placement that closed immediately subsequent to the closing of the IPO. The Company received aggregate proceeds of $ 50.0 million in this concurrent private placement and did not pay underwriting discounts or commissions with respect to the shares of Class A common stock that were sold in the private placement.

Accounting Policies [Abstract]
Basis of Presentation and Summary of Significant Accounting Policies	2. Basis of Presentation and Summary of Significant Accounting Policies Basis of Presentation The accompanying unaudited interim condensed consolidated financial statements and related notes have been prepared in accordance with accounting principles generally accepted in the United States (“GAAP”) and applicable rules and regulations of the United States Securities and Exchange Commission (the “SEC”) regarding interim financial reporting. Accordingly, they do not include all disclosures normally required in annual consolidated financial statements prepared in accordance with GAAP. Therefore, these unaudited condensed consolidated financial statements and related notes should be read in conjunction with the audited consolidated financial statements and the related notes included in the Company's Form 10-K for the year ended December 31, 2021 filed with the SEC on March 3, 2022, (the "2021 Form 10-K"). These unaudited interim condensed consolidated financial statements have been prepared on the same basis as the annual financial statements and reflect all adjustments, which include only normal recurring adjustments necessary for the fair statement of the Company’s financial position, results of operations, comprehensive income, changes in stockholders' equity and cash flows for the periods presented. The results of operations for the three and six months ended June 30, 2022 and 2021 are not necessarily indicative of the results to be expected for the full year or any other future interim or annual period. Stock Split On May 10, 2021, the Company effected a 5 -for-1 forward stock split of its common stock. In connection with the forward stock split, each issued and outstanding share of common stock, automatically and without action on the part of the holders, became five shares of common stock. The par value per share of common stock was not adjusted. All share, per share and related information presented in the unaudited interim condensed consolidated financial statements and accompanying notes have been retroactively adjusted, where applicable, to reflect the impact of the stock split. Principles of Consolidation The unaudited interim condensed consolidated financial statements include the accounts of the Company and its wholly owned subsidiaries. All intercompany accounts and balances have been eliminated upon consolidation. Segment Information Operating segments are defined as components of an enterprise for which separate financial information is available and evaluated regularly by the chief operating decision maker (“CODM”) in deciding how to make operating decisions, allocate resources and assess performance. The Company has three operating segments based on geography. The United States segment represents the vast majority of the Company’s consolidated net sales and gross profit. The additional two operating segments, Canada and India, do not meet the quantitative thresholds for separate reporting, either individually or in the aggregate. None of the operating segments qualified for aggregation. The Company’s CODM is its Chief Executive Officer. The CODM evaluates the performance of the Company’s operating segments based on revenue and gross profit. The Company does not analyze discrete segment balance sheet information related to long-term assets. All other financial information is presented on a consolidated basis. For information regarding the Company’s long-lived assets and revenue by geographic area, see Note 15. Use of Estimates The preparation of consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. Such estimates include revenue recognition, the allowance for credit losses, the lives of tangible and intangible assets, the valuation of acquired intangible assets and the recoverability or impairment of intangible assets, including goodwill, internal-use software development costs, valuation of stock warrants issued, stock-based compensation, and accounting for income taxes. The Company bases its estimates on historical experience and also on assumptions that management considers reasonable. The Company assesses these estimates on a regular basis; however, actual results could differ from these estimates. Custodial Accounts The Company has established a relationship with its merchant processors to act as collection and paying agents, whereby a merchant processor receives funds from customers and forwards such funds to the respective Paymentus client, based on the instructions received from the Company. These merchant processors act as custodians of the cash received, and the Company has no legal ownership rights to the funds held in such custodial accounts and does not control the use of these funds. As the Company does not take ownership of the funds, these custodial accounts are not included in the Company’s consolidated balance sheets. The balance of cash in the custodial accounts held by these merchant processors was $ 41.3 million and $ 47.4 million as of June 30, 2022 and December 31, 2021 , respectively. Restricted Funds Held for Financial Institutions and Financial Institution Funds In-Transit Restricted funds held for financial institutions and the corresponding liability of financial institution funds in-transit represent the timing differences arising between the amounts the Company's sponsor bank receives from the sending financial institutions and the amounts disbursed to the recipient financial institutions. The restricted funds held for financial institutions' account is a transaction account maintained at the Company’s sponsor bank for clearing payments from financial institutions (as defined by the U.S. Treasury’s Financial Crimes Enforcement Network) to other financial institutions. Restricted funds held for financial institutions represent restricted cash that, based upon the Company's intent, are restricted solely for satisfying the corresponding obligations to send funds to the various financial institutions. Concentration of Credit Risk Financial instruments that potentially subject the Company to credit risk primarily consist of cash, cash equivalents, and accounts receivable. The Company maintains its cash and cash equivalents with high-quality financial institutions with investment-grade ratings. For accounts receivable, the Company is exposed to credit risk in the event of nonpayment by customers to the extent of the amounts recorded in the consolidated balance sheets. No customer accounted for more than 10 % of revenue for either of the three or six months ended June 30, 2022 and 2021. No customer accounted for more than 10 % of accounts receivable as of June 30, 2022 , while one customer accounted for more than 10 % of accounts receivable as of December 31, 2021 . Summary of Significant Accounting Policies The Company’s significant accounting policies are discussed in Note 2, “Basis of Presentation and Summary of Significant Accounting Policies” in the Notes to Consolidated Financial Statements as of December 31, 2021 and 2020 and for the years ended December 31, 2021 and 2020 included in the 2021 Form 10-K. There have been no significant changes to these policies during the three and six months ended June 30, 2022 . Accounting Pronouncements The Company is provided the option to adopt new or revised accounting guidance as an “emerging growth company” under the Jumpstart Our Business Startups Act of 2012 either (1) within the same periods as those otherwise applicable to public business entities, or (2) within the same time periods as non-public business entities, including early adoption when permissible. With the exception of standards the Company elected to early adopt, when permissible, the Company has elected to adopt new or revised accounting guidance within the same time period as non-public business entities, as indicated below. Accounting Pronouncements Not Yet Adopted In October 2021, the FASB issued ASU 2021-08, "Business Combinations (Topic 805): Accounting for Contract Assets and Contract Liabilities from Contracts with Customers" ("ASU 2021-08") . ASU 2021-08 will require companies to apply the definition of a performance obligation under ASU 2014-09 , Revenue from contracts with customers (“Topic 606”) to recognize and measure contract assets and contract liabilities relating to contracts with customers that are acquired in a business combination. Under current U.S. GAAP, an acquirer generally recognizes assets acquired and liabilities assumed in a business combination, including contract assets and contract liabilities arising from revenue contracts with customers, at fair value on the acquisition date.

Revenue, Performance Obligations and Contract Balances Disaggregation of Revenue The following table presents a disaggregation of revenue from contracts with customers (in thousands): Three Months Ended June 30, Six Months Ended June 30, 2022 2021 2022 2021 Payment transaction processing revenue $ 118,512 $ 92,446 $ 233,474 $ 183,646 Other 1,457 1,049 3,199 2,071 Total revenue $ 119,969 $ 93,495 $ 236,673 $ 185,717 Remaining Performance Obligations ASU Topic 606 requires disclosure of the aggregate amount of the transaction price allocated to unsatisfied performance obligations. The purpose of this disclosure is to provide additional information about the amounts and expected timing of revenue to be recognized from the remaining performance obligations in our existing contracts. As of June 30, 2022 , the aggregate amount of transaction price allocated to performance obligations that are unsatisfied or partially unsatisfied was $ 4.0 million, which the Company expects to recognize over 80 % within the next four years . The timing of revenue recognition within the next year is largely dependent upon the go-live dates of the Company's contracts. As of June 30, 2022 , the Company has contractual rights under its commercial agreements to receive $ 29.7 million of fixed consideration related to the future minimum guarantees through March 2026. As permitted, the Company has elected to exclude from this disclosure any variable consideration that meets specified criteria. Accordingly, the total unsatisfied or partially unsatisfied performance obligations related to processing services is significantly higher than the amount disclosed. Contract Balances The contract asset balances at June 30, 2022 and December 31, 2021 were $ 6.6 million and $ 5.6 million, respectively, of which $ 1.7 million and $ 1.7 million was included in prepaid expenses and other current assets and $ 4.9 million and $ 3.9 million was included in other long-term assets in the condensed consolidated balance sheets, respectively. During the three months ended June 30, 2022 and 2021, the Company reduced revenue and the related contract assets by $ 0.4 million and $ 0.2 million and for the six months ended June 30, 2022 and 2021, revenue and the related contract assets were reduced by $ 0.8 million and $ 0.2 million. The Company recorded $ 4.0 million and $ 3.9 million of contract liabilities in the condensed consolidated balance sheets as of June 30, 2022 and December 31, 2021 , respectively, of which $ 2.8 million is related to acquisitions during the year ended December 31, 2021 and the remaining amount related to legacy contracts obtained from prior acquisitions associated with the Company’s insignificant other revenue stream and other payments the Company received in advance for services. The change in the contract liabilities is primarily related to timing differences between payment from the customer and the Company’s satisfaction of each performance obligation. Revenue recognized during the three months ended June 30, 2022 and 2021 that was included in the contract liabilities balance at the beginning of each of the periods was $ 0.5 million and $ 0.6 million, respectively. Revenue recognized during the six months ended June 30, 2022 and 2021 that was included in the contract liabilities balance at the beginning of each of the periods was $ 0.8 million and $ 0.6 million, respectively.

The shares of Class A common stock and Class B common stock are identical, except with respect to voting and conversion. Each share of Class A common stock is entitled to one vote. Each share of Class B common stock is entitled to ten votes. Class A and Class B common stock have a par value of $ 0.0001 per share, and are referred to as common stock throughout the notes to the condensed consolidated financial statements, unless otherwise noted. Holders of common stock are entitled to receive any dividends as may be declared from time to time by the board of directors.

Income Tax Disclosure [Abstract]
Income Taxes	13. Income Taxes The Company computes its tax provision for interim periods by applying the estimated annual effective tax rate to year-to-date income from recurring operations and adjusting for discrete items arising in that quarter. However, if the Company is unable to make a reliable estimate of its annual effective tax rate, then the actual effective tax rate for the year-to-date period may be the best estimate. For the three and six months ended June 30, 2021, the Company determined that its annual effective tax rate approach would provide a reliable estimate and therefore used its historical method to calculate its tax provision. However, for the three and six months ended June 30, 2022, the Company used a discrete effective tax rate method as it was determined that the effective tax rate determined using the forecast of ordinary income or loss does not reasonably estimate the effective tax rate to be applied to year-to-date pre-tax (loss) income, and any small changes would result in significant changes in the estimated annual effective tax rate. The Company’s effective tax rate for the three and six months ended June 30, 2022 is ( 17.5 %) and 78.7 %. For the three and six months ended June 30, 2021, the effective tax rate was 85.9 % and 52.8 %. The difference between the Company’s effective tax rate and the U.S. federal statutory rate of 21 % in the above periods was primarily the result of excess tax benefits on stock-based compensation, state taxes, foreign income taxed at different rates and permanent tax adjustments related to nondeductible executive compensation. During the three months ended June 30, 2022, the Company recognized sizable tax deductions for stock-based compensation. These permanent benefits are creating net operating losses that have resulted in a net deferred tax asset. These permanent tax benefits have also created a cumulative history of losses such that the Company has determined that the resulting net deferred tax asset is not more likely than not to be realized. The Company is recording a valuation allowance beginning in the three months ended June 30, 2022 against its U.S. net deferred tax assets.

Earnings Per Share [Abstract]
Net (Loss) Income Per Share Attributable to Common Stock	14. Net (Loss) Income Per Share Attributable to Common Stock Basic net (loss) income per share attributable to common stockholders is computed by deducting the undeclared dividends on the Series A preferred stock from net (loss) income to arrive at net (loss) income attributable to common stock and dividing the net (loss) income attributable to common stockholders by the weighted-average number of shares of common stock outstanding during the period. Diluted net (loss) income per share attributable to common stock is computed by giving effect to all potentially dilutive common stock equivalents to the extent they are dilutive. The dilutive effect of outstanding options, RSUs and warrants is reflected in diluted net (loss) income per share attributable to common stock by application of the treasury stock method. The calculation of diluted net (loss) income per share attributable to common stock excludes all anti-dilutive common shares. The rights of the holders of Class A and Class B common stock are identical, except with respect to voting and conversion. As the liquidation and dividend rights are identical, the undistributed earnings are allocated on a proportionate basis to each class of common stock and the resulting basic and diluted net (loss) income per share attributable to common stockholders are, therefore, the same for both Class A and Class B common stock on both an individual and combined basis. The following table sets forth the computation of basic and diluted net (loss) income per share attributable to common stock (in thousands except share and per share data): Three Months Ended June 30, Six Months Ended June 30, 2022 2021 2022 2021 Numerator: Net (loss) income $ ( 2,451 ) $ 575 $ ( 733 ) $ 4,213 Undeclared dividends on Series A preferred stock — ( 898 ) — ( 2,258 ) Net (loss) income attributable to common stock $ ( 2,451 ) $ ( 323 ) $ ( 733 ) $ 1,955 Denominator: Weighted-average shares of common stock - basic 121,637,711 108,970,604 121,269,688 106,240,091 Dilutive effect of stock options to purchase common stock — — — 5,973,878 Dilutive effect of RSUs — — — — Dilutive effect of warrants — — — 30,085 Weighted-average shares of common stock - diluted 121,637,711 108,970,604 121,269,688 112,244,054 Net (loss) income per share attributable to common stock Basic $ ( 0.02 ) $ — $ ( 0.01 ) $ 0.02 Diluted $ ( 0.02 ) $ — ( 0.01 ) 0.02 The following table summarizes the securities that were excluded from the computation of diluted net income per share attributable to common stock as their inclusion would have been antidilutive: Three Months Ended June 30, Six Months Ended June 30, 2022 2021 2022 2021 Stock options to purchase common stock 5,819,439 7,564,643 6,195,625 1,480 RSUs 624,260 — 588,426 — Warrants 397,944 151,132 397,944 —

Basis of Presentation and Summary of Significant Accounting Policies (Policies)	6 Months Ended

Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The accompanying unaudited interim condensed consolidated financial statements and related notes have been prepared in accordance with accounting principles generally accepted in the United States (“GAAP”) and applicable rules and regulations of the United States Securities and Exchange Commission (the “SEC”) regarding interim financial reporting. Accordingly, they do not include all disclosures normally required in annual consolidated financial statements prepared in accordance with GAAP. Therefore, these unaudited condensed consolidated financial statements and related notes should be read in conjunction with the audited consolidated financial statements and the related notes included in the Company's Form 10-K for the year ended December 31, 2021 filed with the SEC on March 3, 2022, (the "2021 Form 10-K"). These unaudited interim condensed consolidated financial statements have been prepared on the same basis as the annual financial statements and reflect all adjustments, which include only normal recurring adjustments necessary for the fair statement of the Company’s financial position, results of operations, comprehensive income, changes in stockholders' equity and cash flows for the periods presented. The results of operations for the three and six months ended June 30, 2022 and 2021 are not necessarily indicative of the results to be expected for the full year or any other future interim or annual period.
Stock Split	Stock Split On May 10, 2021, the Company effected a 5 -for-1 forward stock split of its common stock. In connection with the forward stock split, each issued and outstanding share of common stock, automatically and without action on the part of the holders, became five shares of common stock. The par value per share of common stock was not adjusted. All share, per share and related information presented in the unaudited interim condensed consolidated financial statements and accompanying notes have been retroactively adjusted, where applicable, to reflect the impact of the stock split.
Principles of Consolidation	Principles of Consolidation The unaudited interim condensed consolidated financial statements include the accounts of the Company and its wholly owned subsidiaries. All intercompany accounts and balances have been eliminated upon consolidation.
Segment Information	Segment Information Operating segments are defined as components of an enterprise for which separate financial information is available and evaluated regularly by the chief operating decision maker (“CODM”) in deciding how to make operating decisions, allocate resources and assess performance. The Company has three operating segments based on geography. The United States segment represents the vast majority of the Company’s consolidated net sales and gross profit. The additional two operating segments, Canada and India, do not meet the quantitative thresholds for separate reporting, either individually or in the aggregate. None of the operating segments qualified for aggregation. The Company’s CODM is its Chief Executive Officer. The CODM evaluates the performance of the Company’s operating segments based on revenue and gross profit. The Company does not analyze discrete segment balance sheet information related to long-term assets. All other financial information is presented on a consolidated basis. For information regarding the Company’s long-lived assets and revenue by geographic area, see Note 15.
Use of Estimates	Use of Estimates The preparation of consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. Such estimates include revenue recognition, the allowance for credit losses, the lives of tangible and intangible assets, the valuation of acquired intangible assets and the recoverability or impairment of intangible assets, including goodwill, internal-use software development costs, valuation of stock warrants issued, stock-based compensation, and accounting for income taxes. The Company bases its estimates on historical experience and also on assumptions that management considers reasonable. The Company assesses these estimates on a regular basis; however, actual results could differ from these estimates.
Custodial Accounts	Custodial Accounts The Company has established a relationship with its merchant processors to act as collection and paying agents, whereby a merchant processor receives funds from customers and forwards such funds to the respective Paymentus client, based on the instructions received from the Company. These merchant processors act as custodians of the cash received, and the Company has no legal ownership rights to the funds held in such custodial accounts and does not control the use of these funds. As the Company does not take ownership of the funds, these custodial accounts are not included in the Company’s consolidated balance sheets. The balance of cash in the custodial accounts held by these merchant processors was $ 41.3 million and $ 47.4 million as of June 30, 2022 and December 31, 2021 , respectively.
Restricted funds held for financial institutions and financial institution funds-in transit	Restricted Funds Held for Financial Institutions and Financial Institution Funds In-Transit Restricted funds held for financial institutions and the corresponding liability of financial institution funds in-transit represent the timing differences arising between the amounts the Company's sponsor bank receives from the sending financial institutions and the amounts disbursed to the recipient financial institutions. The restricted funds held for financial institutions' account is a transaction account maintained at the Company’s sponsor bank for clearing payments from financial institutions (as defined by the U.S. Treasury’s Financial Crimes Enforcement Network) to other financial institutions. Restricted funds held for financial institutions represent restricted cash that, based upon the Company's intent, are restricted solely for satisfying the corresponding obligations to send funds to the various financial institutions.
Concentration of Credit Risk	Concentration of Credit Risk Financial instruments that potentially subject the Company to credit risk primarily consist of cash, cash equivalents, and accounts receivable. The Company maintains its cash and cash equivalents with high-quality financial institutions with investment-grade ratings. For accounts receivable, the Company is exposed to credit risk in the event of nonpayment by customers to the extent of the amounts recorded in the consolidated balance sheets. No customer accounted for more than 10 % of revenue for either of the three or six months ended June 30, 2022 and 2021. No customer accounted for more than 10 % of accounts receivable as of June 30, 2022 , while one customer accounted for more than 10 % of accounts receivable as of December 31, 2021 .
Summary of Significant Accounting Policies	Summary of Significant Accounting Policies The Company’s significant accounting policies are discussed in Note 2, “Basis of Presentation and Summary of Significant Accounting Policies” in the Notes to Consolidated Financial Statements as of December 31, 2021 and 2020 and for the years ended December 31, 2021 and 2020 included in the 2021 Form 10-K. There have been no significant changes to these policies during the three and six months ended June 30, 2022 .
Accounting Pronouncements	Accounting Pronouncements The Company is provided the option to adopt new or revised accounting guidance as an “emerging growth company” under the Jumpstart Our Business Startups Act of 2012 either (1) within the same periods as those otherwise applicable to public business entities, or (2) within the same time periods as non-public business entities, including early adoption when permissible. With the exception of standards the Company elected to early adopt, when permissible, the Company has elected to adopt new or revised accounting guidance within the same time period as non-public business entities, as indicated below. Accounting Pronouncements Not Yet Adopted In October 2021, the FASB issued ASU 2021-08, "Business Combinations (Topic 805): Accounting for Contract Assets and Contract Liabilities from Contracts with Customers" ("ASU 2021-08") . ASU 2021-08 will require companies to apply the definition of a performance obligation under ASU 2014-09 , Revenue from contracts with customers (“Topic 606”) to recognize and measure contract assets and contract liabilities relating to contracts with customers that are acquired in a business combination. Under current U.S. GAAP, an acquirer generally recognizes assets acquired and liabilities assumed in a business combination, including contract assets and contract liabilities arising from revenue contracts with customers, at fair value on the acquisition date. ASU 2021-08 will result in the acquirer recording acquired contract assets and liabilities on the same basis that would have been recorded by the acquiree before the acquisition under ASU Topic 606. ASU 2021-08 is effective for fiscal years beginning after December 15, 2022 for public entities and December 15, 2023 for all other entities, with early adoption permitted. The Company is currently evaluating the impact of this ASU on its condensed consolidated financial statements.
