| Accounting Policies [Abstract] | |
| Basis of Presentation and Principles of Consolidation | Basis of Presentation and Principles of Consolidation 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, 2025 filed with the SEC on February 24, 2026 (the “2025 Form 10-K”). These unaudited interim condensed consolidated financial statements have been prepared on the same basis as the annual financial statements and, in the opinion of management, reflect all adjustments, which include only normal recurring adjustments, necessary for the fair statement of the Company’s financial position, results of operations and comprehensive income, changes in stockholders' equity and cash flows for the periods presented. The results of operations for the three and nine months ended September 30, 2026 and 2025 are not necessarily indicative of the results to be expected for the full year or any other future interim or annual period. 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. |
| Use of Estimates | Use of Estimates The preparation of condensed consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported in the condensed consolidated financial statements and accompanying notes. Such estimates include revenue recognition, cost of revenue recognition, the allowance for credit losses, the useful lives of tangible and 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 $206.1 million and $215.7 million as of September 30, 2026 and December 31, 2025, respectively. |
| Concentration of Credit Risk | Concentration of Credit Risk Financial instruments that potentially subject the Company to credit risk primarily consist of cash, cash equivalents, accounts receivable and short-term deposits. The Company maintains its cash and cash equivalents and short-term deposits 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 condensed consolidated balance sheets. No customer accounted for more than 10% of revenue for either of the three or nine months ended September 30, 2026 and 2025. As of September 30, 2026 and December 31, 2025, one reseller accounted for more than 10% of accounts receivable. |
| Segment Information | Segment Information The Company operates as a single operating and reportable segment. The Company’s chief operating decision maker ("CODM") is its Chief Executive Officer, and the CODM evaluates financial performance and makes resource allocation decisions based on consolidated financial information. The measure of segment profit or loss that the CODM uses to allocate resources and assess performance is the Company’s consolidated net income, as reported on the condensed consolidated statements of operations and comprehensive income. The CODM uses consolidated net income to assess overall Company performance, monitor progress toward financial targets, and make strategic decisions regarding the allocation of resources across functions and initiatives. The accounting policies applied to the segment are the same as those described in the summary of significant accounting policies. All expense categories on the condensed consolidated statements of operations and comprehensive income are significant, and there are no other significant expenses that are reviewed or provided to the CODM that would require disclosure. Assets provided to the CODM are consistent with those reported on the condensed consolidated balance sheets. Information related to the Company’s products and services is disclosed in Note 1. Information about geographical distribution of the Company’s revenue and long-lived assets is disclosed in Notes 3 and 4, respectively. |
| 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, 2025 and 2024 and for the years ended December 31, 2025, 2024 and 2023 included in the 2025 Form 10-K. There have been no significant changes to these policies during the three and nine months ended September 30, 2026. |
| Recently Adopted Accounting Standards | Recently Adopted Accounting Standards Accounting Standards Updates ("ASUs") not listed below were assessed and determined to be either not applicable or not expected to have a material impact on the condensed consolidated financial statements. In July 2025, the FASB issued ASU 2025-05, Measurement of Credit Losses for Accounts Receivable and Contract Accounting Pronouncements Not Yet Adopted On November 4, 2024, the FASB issued new guidance requiring additional disclosure of the nature of expenses included in the income statement in response to longstanding requests from investors for more information about an entity’s expenses. The new standard requires disclosures about specific types of expenses included in the expense captions presented on the face of the income statement as well as disclosures about selling expenses. ASU 2024-03, Disaggregation of Income Statement Expenses (DISE), applies to all public business entities (PBEs) and is effective for annual reporting periods beginning after December 15, 2026 and interim reporting periods within annual reporting periods beginning after December 15, 2027. The requirements will be applied prospectively with the option for retrospective application. Early adoption is permitted. The adoption of ASU 2024-03 is not expected to have a material impact on the Company's financial position or results of operations. In September 2025, the FASB issued ASU 2025-06, Intangibles – Goodwill and Other – Internal-Use Software In December 2025, the FASB issued ASU 2025-11, Interim Reporting (Topic 270): Narrow-Scope Improvements. The amendments improve the codification guidance for interim reporting and require that entities provide specific disclosures in interim periods that were previously only required in annual financial statements. The new guidance is effective for fiscal years beginning after December 15, 2027, and interim periods within those fiscal years, with early adoption permitted. The Company is currently evaluating the impact of adopting this new guidance on its future interim financial disclosures. |
