Organization, Consolidation and Presentation of Financial Statements [Abstract]
Nature of Business and Basis of Presentation	1. Nature of Business and Basis of Presentation EngageSmart, Inc. and its subsidiaries (together referred to herein as the “Company” or “EngageSmart”) is a leading provider of vertically tailored customer engagement software and integrated payments solutions. EngageSmart offers single instance, multi-tenant, true Software-as-a-Service (“SaaS”) vertical solutions, including SimplePractice, InvoiceCloud, HealthPay24 and DonorDrive, that are designed to simplify the Company's customers' engagement with its clients by driving digital adoption and self-service. The Company serves customers across several core verticals: Health & Wellness, Government, Utilities, Financial Services, Healthcare and Giving. EngageSmart's solutions are purpose-built for each of the Company's verticals and they simplify and automate mission-critical workflows such as scheduling, client onboarding, client communication, paperless billing, and electronic payment processing. EngageSmart is headquartered in Braintree, Massachusetts with additional locations throughout the United States. Secondary Offering On February 28, 2023, the Company entered into an underwriting agreement (the “Underwriting Agreement”) with Goldman Sachs & Co. LLC and J.P. Morgan Securities LLC, as representatives of the several underwriters named therein, and certain of the Company’s stockholders, including affiliate s of General Atlantic, L.P ("General Atlantic") and Summit Partners and certain members of the Company’s management (collectively the “Selling Stockholders”), relating to an underwritten public offering (the “Secondary Offering”) of 8,000,000 shares of the Company’s common stock at a pri ce to the public of $ 19.00 per share, with an option exercisable by the underwriters for 30 days to purchase up to an additional 1,200,000 shares of common stock from certain of the Selling Stockholders at the public offering price, less underwriting discounts and commissions. In March 2023, pursuant to the Underwriting Agreement, the Selling Stockholders sold an aggregate of 9,200,000 shares of common stock in the Secondary Offering. The Company did no t receive any of the proceeds from the sale of common stock, with all proceeds going to the Selling Stockholders. In connection with the Secondary Offering, the Company incurred costs of $ 1.6 million during the six months ended June 30, 2023, which are included within general and administrative expenses on the condensed consolidated statement of operations and comprehensive income. Basis of Presentation The accompanying condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States (“GAAP”) and include the accounts of the Company and its wholly owned subsidiaries. All intercompany accounts and transactions between the Company and its subsidiaries have been eliminated in consolidation. For all the periods reported in these condensed consolidated financial statements, the Company has not and does not have any material revenue-generating operations on a standalone basis, and all the material revenue-generating operations of the Company are conducted by its subsidiaries. Certain information and note disclosures normally included in the consolidated financial statements prepared in accordance with GAAP have been condensed or omitted. Therefore, these condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements for the year ended December 31, 2022, included in the Company's 2022 Form 10-K. In the opinion of management, the interim condensed consolidated financial statements reflect all adjustments, consisting of normal recurring adjustments, necessary for a fair presentation of the Company’s financial position for the periods presented. The results for the interim periods presented are not necessarily indicative of future results.

Accounting Policies [Abstract]
Summary of Significant Accounting Policies	2. Summary of Significant Accounting Policies The Company’s significant accounting policies are discussed in Note 2 - Summary of Significant Accounting Policies within the notes to consolidated financial statements for the year ended December 31, 2022, included in the Company's 2022 Form 10-K. There have been no significant changes to these policies during the six months ended June 30, 2023, except as noted below. Risk of Concentrations of Credit and Significant Customers Financial instruments that potentially expose the Company to concentrations of credit risk consist primarily of cash, cash equivalents, and accounts receivable. The Company's cash and cash equivalents are primarily maintained in accounts with three major financial institutions in the United States. At times, the Company may maintain cash and cash equivalent balances in excess of Federal Deposit Insurance Corporation ("FDIC") limits. The Company does not believe that it is subject to unusual credit risk beyond the normal credit risk associated with commercial banking relationships. Significant customers are those that accounted for 10 % or more of the Company’s total revenue or accounts receivable during any period presented herein. During the six months ended June 30, 2023 and 2022, no customer accounted for 10 % or more of revenue. As of June 30, 2023 and December 31, 2022, no customer accounted for 10 % or more of accounts receivable. Recently Adopted Accounting Prono uncements 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"), which requires the recognition and measurement of contract assets and liabilities acquired in a business combination in accordance with ASC 606, Revenue from Contracts with Customers ("ASC 606"). ASU 2021-08 is effective for fiscal years beginning after December 15, 2022 and, if adopted early, requires the retrospective method of transition applied to transactions occurring on or after the beginning of the fiscal year of adoption. The Company adopted this standard effective January 1, 2023 on a prospective basis, and it did no t have a material impact on its consolidated financial statements.

Revenue from Contract with Customer [Abstract]
Revenue	3. Revenue Revenue Disaggregated The Company disaggregates revenue from contracts with customers by reportable segment and revenue type, as the Company believes it best depicts how the nature, amount, timing and uncertainty of revenue and cash flows are affected by economic factors and is consistent with the manner in which the Company operates the business. The Company generates a significant majority of its revenue in the Enterprise Solutions segment from transaction and usage-based revenue and a majority of its revenue in the SMB Solutions segment from subscription revenue. The following table depicts disaggregated revenue by segment and revenue type (in thousands): Three Months Ended June 30, Six Months Ended June 30, 2023 2022 2023 2022 Enterprise Solutions Transaction and usage-based $ 38,148 $ 29,989 $ 73,554 $ 58,308 Subscription 2,676 2,156 5,231 4,237 Other 484 872 1,168 1,332 Total Enterprise Solutions revenue 41,308 33,017 79,953 63,877 SMB Solutions Transaction and usage-based 16,158 11,237 30,730 22,264 Subscription 36,629 29,225 71,532 54,277 Other 314 383 626 806 Total SMB Solutions revenue 53,101 40,845 102,888 77,347 Total revenue $ 94,409 $ 73,862 $ 182,841 $ 141,224 Contract Assets and Liabilities Contract assets are rights to consideration in exchange for goods or services that the entity has transferred to a customer when that right is conditional on something other than the passage of time. Contract assets are transferred to accounts receivable once the rights become unconditional. The Company did no t have contract assets as of June 30, 2023 or December 31, 2022. Contract liabilities (deferred revenue) primarily consist of billings and payments received in advance of revenue recognition. The Company primarily bills and collects payments from customers for its services in advance on a monthly, quarterly or annual basis. Contract liabilities are recognized as revenue when services are performed and all other revenue recognition criteria have been met. Amounts expected to be recognized as revenue within 12 months of the balance sheet date are classified as current deferred reve nue and amounts expected to be recognized as revenue beyond 12 months of the balance sheet date are classified as non-current deferred revenue. The Company had current deferred revenue of $ 8.9 million and $ 8.2 million as of June 30, 2023 and December 31, 2022, respectively. Non-current deferred revenue was $ 0.3 million as of June 30, 2023 and December 31, 2022. During the six months ended June 30, 2023, the Company recognized revenue of $ 7.5 million from the deferred revenue balance as of December 31, 2022. During the six months ended June 30, 2022, the Company recognized revenue of $ 6.0 million from the deferred revenue balance as of December 31, 2021. Remaining Performance Obligations ASC 606 requires disclosure of the aggregate amount of the transaction price allocated to unsatisfied performance obligations. As permitted by ASC 606, the Company has elected to exclude from this disclosure any contracts with an original duration of one year or less and any variable consideration that meets specified criteria. For contracts greater than one year in length, the Company's most significant performance obligations consist of variable consideration. Such variable consideration meets the specified criteria for the disclosure exclusion; therefore, the majority of the aggregate amount of transaction price that is allocated to performance obligations that have not yet been satisfied is variable consideration that is not required for this disclosure.

Net Income Per Share

Earnings Per Share [Abstract]
Net Income Per Share	4. Net Income Per Share Basic net income per share is calculated by dividing net income by the weighted average number of shares of common stock outstanding during the period. Diluted net income per share is calculated by dividing net income by the sum of the weighted average number of shares of common stock and potentially dilutive securities outstanding during the period using the treasury stock method. For the periods in which the Company incurs a net loss, the dilutive effect of the Company’s outstanding common stock equivalents is not included in the calculation as the effect would be anti-dilutive. The following table sets forth the computation of basic and diluted net income per share: Three Months Ended June 30, Six Months Ended June 30, 2023 2022 2023 2022 (in thousands, except share and per share amounts) Numerator: Net income $ 4,338 $ 6,879 $ 8,462 $ 8,938 Denominator: Weighted average shares outstanding, basic 166,902,466 162,991,881 166,632,637 162,569,871 Effect of potential dilutive shares 3,066,592 5,958,988 3,305,839 6,413,439 Weighted average shares outstanding, diluted 169,969,058 168,950,869 169,938,476 168,983,310 Net income per share, basic $ 0.03 $ 0.04 $ 0.05 $ 0.05 Net income per share, diluted $ 0.03 $ 0.04 $ 0.05 $ 0.05 The Company excluded the following potential shares of common stock, presented based on amounts outstanding at each period end, from the computation of diluted net income per share for the periods indicated because including them would have had an anti-dilutive effect: Three Months Ended June 30, Six Months Ended June 30, 2023 2022 2023 2022 Options to purchase shares 316,865 457,964 317,775 518,998 Unvested restricted stock units 1,866,878 716,015 1,132,484 597,339 Total 2,183,743 1,173,979 1,450,259 1,116,337

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	13. Commitments and Contingencies Non-Cancellable Commitments As of June 30, 2023, the Company had non-cancellable commitments to vendors primarily consisting of subscriptions to third party software products. Obligations under contracts that are cancellable or with a remaining term of 12 months or less are not included. As of June 30, 2023, future minimum payments under other non-cancellable agreements were as follows (in thousands): Remainder of 2023 $ 2,231 2024 2,937 2025 514 2026 88 2027 — Thereafter — Total $ 5,770 Contingent Value Payments In 2019, the CVR Bonus Award Plan ("CVR Plan") was established for the benefit of option holders as of February 11, 2019 in the event that holders of Class A-1 common shares of EngageSmart, LLC (the Company's predecessor) receive cash distributions in connection with certa in exit events specified under EngageSmart, LLC's LLC Agreement of at least $ 889.1 million (the “Performance Threshold”). Subject to the achievement of the Performance Threshold, CVR Unit Awards ("CVR Units") entitle the holder, subject generally to the holder’s continued employment through the date of payment, to a pro-rata portion of a bonus pool (based on a participant’s share of CVR Units held). The maximum amount of this bonus pool was capped at $ 9.5 million, of which, $ 6.0 million remains outstanding as of June 30, 2023. No compensation expense has been recognized in relation to the CVR Plan as the Company has determined that achievement of the Performance Threshold is not probable as of June 30, 2023. In connection with the Company’s IPO in 2021, the CVR Plan was amended to reflect the conversion of EngageSmart, LLC to EngageSmart, Inc. and the CVR Units otherwise remain subject to substantially the same terms and conditions applicable immediately prior to the Company’s IPO. Following the IPO and the conversion of EngageSmart, LLC to EngageSmart, Inc. (and related transactions), General Atlantic subscribed and received 288,344 additional shares of common stock in the Company, with the value of each share based on the public offering price of the shares of common stock sold by the Company in the IPO. As consideration for the additional shares of common stock, General Atlantic entered into a promissory note with the Company, which requires General Atlantic to make a capital contribution to the Company equal to the amount of any future payments to be made by the Company to holders of CVR Units pursuant to the CVR Plan, which such payments would be triggered by the events specified under the amended CVR Plan. In the event the CVR Units are forfeited or the Performance Threshold is not met, General Atlantic will not be required to make any payments under the promissory note and will keep the shares issued. Indemnification Agreements In the normal course of business, the Company may provide indemnification of varying scope and terms to third parties and may enter into commitments and guarantees (“Agreements”) under which it may be required to make payments. The duration of these Agreements varies, and in certain cases, may be indefinite with no limit to the Company’s maximum potential payment exposure. In addition, the Company has obligations with certain members of its board of directors and certain executive officers that will require the Company, among other things, to indemnify them against certain liabilities that may arise by reason of their status or service as directors and/or officers. To date, the Company has not incurred any material costs as a result of such indemnifications. The Company does not believe that the outcome of any claims under any indemnification arrangements will have a material effect on its financial position, results of operations or cash flows, and it has not accrued any liabilities related to such obligations in its condensed consolidated financial statements as of June 30, 2023 and December 31, 2022. Legal Proceedings The Company is from time to time subject to various other legal proceedings and claims, either asserted or unasserted, which arise in the ordinary course of business. The Company routinely assesses its current litigation and/or threatened litigation as to the probability of ultimately incurring a liability. In situations where the Company assesses the likelihood of loss as probable, the Company records its best estimate of the ultimate loss if reasonably possible to estimat e. While the outcome of these claims cannot be predicted with certainty, the Company believes that these pending or threatened legal proceedings or claims could not have a material impact on the Company’s condensed consolidated financial statements.

Segment Reporting [Abstract]
Segment and Geographic Information	14. Segment and Geographic Information Segment Information The Company has determined that its chief executive officer is its chief operating decision maker (“CODM”) and the Company is organized into two reportable segments: Enterprise Solutions and SMB Solutions. The reportable segments were determined based on how the CODM reviews business performance and makes decisions about resources to be allocated. The Enterprise Solutions segment is primarily engaged in providing SaaS solutions that simplify customer-client engagement primarily through electronic billing and digital payments. Enterprise solutions are built to address the unique needs of specific verticals: Government, Utilities, Financial Services, Healthcare and Giving. For the Enterprise Solutions segment, the Company integrates directly with its customers’ core software systems and utilizes a partner-assisted direct sales model for purposes of its go-to-market strategy. The Company generates a significant majority of its revenue in this segment from transaction and usage-based revenue. For the six months ended June 30, 2023, this segment generated 44 % of total revenue. The SMB Solutions segment is primarily engaged in providing end-to-end practice management solutions geared toward the Health & Wellness industry. For the Company's SMB Solutions segment, the Company primarily relies on a free trial to paid customer sales model. The Company generates interest for its offerings in the Company's SMB Solutions segment through a combination of search engine optimization, word-of-mouth, paid customer referrals, and search engine marketing. The Company generates a majority of its revenue in this segment from subscription revenue. For the six months ended June 30, 2023, this segment generated 56 % of total revenue. The CODM evaluates segment operating performance using revenue and Adjusted EBITDA, as defined below, from reportable segments to make resource allocation decisions and to evaluate segment performance. Adjusted EBITDA assists management in comparing the Company’s performance on a consistent basis for purposes of business decision-making. The Company defines Adjusted EBITDA as net income excluding interest income (expense), net; provision for (benefit from) income taxes; depreciation; and amortization of intangible assets, as further adjusted for transaction-related expenses and stock-based compensation. Adjusted EBITDA from reportable segments excludes unallocated corporate costs which are primarily comprised of costs for accounting, finance, legal, human resources and costs for certain executives supporting overall business strategy and execution. The following table sets forth the revenue and Adjusted EBITDA results attributable to each reportable segment and includes a reconciliation of the totals reported for the reportable segments to the applicable line items in the Company’s accompanying condensed consolidated statements of operations and comprehensive income (in thousands): Three Months Ended June 30, Six Months Ended June 30, 2023 2022 2023 2022 Revenue Enterprise Solutions $ 41,308 $ 33,017 $ 79,953 $ 63,877 SMB Solutions 53,101 40,845 102,888 77,347 Total revenue 94,409 73,862 182,841 141,224 Adjusted EBITDA Enterprise Solutions 7,198 4,285 13,621 8,761 SMB Solutions 20,197 15,907 38,665 28,925 Total Adjusted EBITDA from reportable segments 27,395 20,192 52,286 37,686 Unallocated corporate expenses ( 8,016 ) ( 8,227 ) ( 15,585 ) ( 15,164 ) Total Adjusted EBITDA 19,379 11,965 36,701 22,522 Reconciling items: Interest income (expense), net 3,205 210 5,625 122 Amortization of intangible assets ( 3,900 ) ( 3,899 ) ( 7,800 ) ( 7,800 ) Depreciation ( 1,031 ) ( 733 ) ( 2,023 ) ( 1,473 ) Transaction-related expenses ( 510 ) — ( 2,222 ) 38 Stock-based compensation ( 5,102 ) ( 3,327 ) ( 10,002 ) ( 6,314 ) Income before income taxes 12,041 4,216 20,279 7,095 Provision for (benefit from) income taxes 7,703 ( 2,663 ) 11,817 ( 1,843 ) Net income $ 4,338 $ 6,879 $ 8,462 $ 8,938 The Company’s CODM does not separately evaluate assets by segment, and therefore assets by segment are not presented.

Accounting Policies [Abstract]
Risk of Concentrations of Credit and Significant Customers	Risk of Concentrations of Credit and Significant Customers Financial instruments that potentially expose the Company to concentrations of credit risk consist primarily of cash, cash equivalents, and accounts receivable. The Company's cash and cash equivalents are primarily maintained in accounts with three major financial institutions in the United States. At times, the Company may maintain cash and cash equivalent balances in excess of Federal Deposit Insurance Corporation ("FDIC") limits. The Company does not believe that it is subject to unusual credit risk beyond the normal credit risk associated with commercial banking relationships. Significant customers are those that accounted for 10 % or more of the Company’s total revenue or accounts receivable during any period presented herein. During the six months ended June 30, 2023 and 2022, no customer accounted for 10 % or more of revenue. As of June 30, 2023 and December 31, 2022, no customer accounted for 10 % or more of accounts receivable.
