Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Summary of Significant Accounting Policies Basis of Presentation The accompanying unaudited interim Consolidated Financial Statements include the accounts of ServiceSource International, Inc. and its wholly owned subsidiaries and have been prepared in accordance with GAAP and with the instructions to Form 10-Q and Article 8 of Regulation S-X for interim financial information. All intercompany balances and transactions have been eliminated in consolidation. These financial statements do not include all the information required by GAAP for annual financial statements. The unaudited Consolidated Balance Sheet as of December 31, 2020 has been derived from the Company’s audited annual Consolidated Financial Statements included in our annual report on Form 10-K for the year ended December 31, 2020 filed with the SEC on February 24, 2021. In the opinion of management, these Consolidated Financial Statements reflect all adjustments, including normal recurring adjustments, management considers necessary for a fair presentation of the Company’s financial position, operating results, and cash flows for the interim periods presented. These Consolidated Financial Statements and accompanying notes should be read in conjunction with our audited Consolidated Financial Statements and the notes thereto for the year ended December 31, 2020, included in our annual report on Form 10-K. Interim results are not necessarily indicative of results for the entire year. Use of Estimates The preparation of the Consolidated Financial Statements in accordance with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the Consolidated Financial Statements and the reported amount of net revenue and expenses during the reporting period. The Company bases its estimates and judgments on historical experience and on various assumptions that it believes are reasonable under the circumstances. The Company has considered the effects of the COVID-19 pandemic in determining its estimates. However, future events are difficult to predict and subject to change, especially with the risks and uncertainties related to the impact of the COVID-19 pandemic, which could cause estimates and judgments to require adjustment. Actual results and outcomes may differ from our estimates. Cash Equivalents and Restricted Cash The Company follows a three-tier fair value hierarchy, which is described in detail in the Company's Annual Report on Form 10-K for the year ended December 31, 2020. Cash equivalents consist of highly liquid investments with original maturities of three months or less at the time of purchase and are classified as a Level 1 investment. Restricted cash consists of cash in money market accounts that are used to secure letters of credit in connection with two of our leased facilities. Restricted cash is recorded within "Other assets" in the Consolidated Balance Sheets and is classified as a Level 1 investment. The Company had restricted cash of $2.3 million as of March 31, 2021 and December 31, 2020. The Company did not have any other financial instruments or debt measured at fair value as of March 31, 2021 and December 31, 2020. There were no transfers between levels during the three months ended March 31, 2021 and 2020. Government Assistance During 2020, ServiceSource received various grants from the Singapore government, including the Job Support Scheme, which assists enterprises in retaining their local employees during the COVID-19 pandemic. ServiceSource received $1.3 million related to these grants during the year ended December 31, 2020 and is expected to receive an additional $0.2 million through August 2021. There are no conditions to repay the grants. Government grants are recognized in the Company's Consolidated Statements of Operations during the same period that the expenses related to the grant are incurred if there is reasonable assurance the grant will be received, and the Company has complied with any conditions attached to the grant. New Accounting Standards Adopted Income Taxes In December 2019, the FASB issued an ASU that simplifies the accounting for income taxes by eliminating certain exceptions to the guidance in ASC 740 related to the approach for intraperiod tax allocation, the methodology for calculating income taxes in an interim period and the recognition of deferred tax liabilities for outside basis differences. This ASU is effective for annual periods and interim periods for those annual periods beginning after December 15, 2020, with early adoption permitted. The Company adopted this standard effective January 1, 2021 and the effects of this standard were applied prospectively to eligible costs incurred on or after January 1, 2021. The adoption of this standard did not have a material impact on the Consolidated Financial Statements. New Accounting Standards Issued but Not yet Adopted Financial Instruments - Credit Losses In June 2016, the FASB issued an ASU that amends the measurement of credit losses on financial instruments and requires measurement and recognition of expected versus incurred credit losses for financial assets held. This ASU is effective for annual periods and interim periods for those annual periods beginning after December 15, 2022, with early adoption permitted. This standard will apply to the Company's accounts receivable and contract assets. Based on our current analysis, the Company does not expect the adoption to have a material impact on the Consolidated Financial Statements as credit losses from trade receivables have historically been insignificant. The Company will adopt this standard effective January 1, 2023.

Debt Disclosure [Abstract]
Debt	Debt Revolving Line of Credit In July 2018, the Company entered into a $40.0 million Revolver that allows it and the other Borrower named therein to borrow against their domestic receivables as defined in the Credit Agreement. The Revolver matures July 2021 and bears interest at a variable rate per annum based on the greater of the prime rate, the Federal Funds rate plus 0.50% or the one-month LIBOR rate plus 1.00%, plus, in each case, a margin of 1.00% for base rate borrowings or 2.00% for Eurodollar borrowings. As of March 31, 2021, the Company had $15.0 million of borrowings under the Revolver through a one-month Eurodollar borrowing at an effective interest rate of 2.11% maturing April 2021. An additional $14.7 million was available for borrowing under the Revolver as of March 31, 2021. The Eurodollar borrowings may be extended upon maturity, converted into a base rate borrowing upon maturity or require an incremental payment if the borrowing base decreases below the current amount outstanding during the term of the Eurodollar borrowing. Subsequent to March 31, 2021, the one-month $15.0 million Eurodollar borrowing was extended at an effective interest rate of approximately 2.11% maturing May 2021. The obligations under the Credit Agreement are secured by substantially all the assets of the Borrowers and certain of their subsidiaries, including pledges of equity in certain of the Company’s subsidiaries. The Revolver has financial covenants which the Company was in compliance with as of March 31, 2021 and December 31, 2020. Interest Expense Interest expense related to the amortization of debt issuance costs and interest expense associated with the Company's debt obligation was $0.1 million and $0.1 million for the three months ended March 31, 2021 and 2020, respectively.

Stock-Based Compensation	Stock-Based Compensation ESPP The Company previously offered an ESPP until its expiration in February 2021. 2021 PSU Awards During March 2021, the Company granted PSUs under the 2020 Plan to certain executives in which the number of shares ultimately received depends on the Company's achievement of two performance goals for fiscal year 2021 and a rTSR modifier based on the Company's rTSR for fiscal years 2021, 2022, and 2023 compared to a peer group. The aggregate target number of shares subject to these awards is 0.8 million. The awards were valued on the grant date using a Monte Carlo simulation for the rTSR modifier and using the Company’s closing stock price for the performance metrics for an aggregate grant date fair value of $1.2 million. The number of shares ultimately received related to these awards will range from 0% to 173% of the participant's target award and will vest on the third anniversary of the grant date. The Company's expense will be recognized over the service period and adjusted based on estimated achievement of the performance goals. Additionally, certain senior leaders elected to receive a portion of their annual cash corporate incentive plan in PSUs. The Company granted the PSUs under the 2020 Plan during March 2021. The number of shares ultimately received depends on the Company's achievement of specified revenue, Adjusted EBITDA, and free cash flow performance goals for fiscal year 2021. The aggregate target number of shares subject to these awards is 0.4 million. The awards were valued using the Company's closing stock price on the grant date and had an aggregate grant date fair value of $0.6 million. The number of shares ultimately received related to these awards ranges from 0% to 200% of the participant's target award and will vest on the first anniversary of the grant date. The Company's expense will be recognized over the service period and adjusted based on estimated achievement of the performance targets.

Potential shares of common stock that are not included in the determination of diluted net loss per share because they are anti-dilutive for the periods presented consist of stock options and unvested RSUs and PSUs. The Company excluded from diluted earnings per share the weighted-average common share equivalents related to 1.2 million and 4.2 million shares for the three months ended March 31, 2021 and 2020, respectively, because their effect would have been anti-dilutive.

Restructuring and Related Activities [Abstract]
Restructuring and Other Related Costs	Restructuring and Other Related Costs The Company has undergone restructuring efforts to better align its cost structure with its business and market conditions. These restructuring efforts include severance and other employee costs, lease and other contract termination costs and asset impairments. Severance and other employee costs include severance payments, related employee benefits, stock-based compensation related to the accelerated vesting of certain equity awards and employee-related legal fees. Lease and other contract termination costs include charges related to lease consolidation and abandonment of spaces no longer utilized and the cancellation of certain contracts with outside vendors. Asset impairments include charges related to leasehold improvements and furniture in spaces vacated or no longer in use. The restructuring plans and future cash outlays are recorded in "Accrued expenses," "Accrued compensation," and "Other long-term liabilities" in the Consolidated Balance Sheets as of March 31, 2021 and December 31, 2020. During 2020, the Company announced a restructuring effort to align with its virtual-first operating model and reduce the operating cost structure resulting in a reduction of headcount and office lease costs. The Company recognized charges related to this restructuring effort of $0.9 million for the three months ended March 31, 2021 and expects to incur approximately $0.1 million in additional costs through 2021.

Income Taxes

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes The Company is subject to taxation in the U.S. and various state and foreign jurisdictions. Earnings from non-U.S. activities are subject to local country income tax. The Company computes its quarterly income tax provision by using a forecasted annual effective tax rate and adjusts for any discrete items arising during the quarter. The primary difference between the effective tax rate and the federal statutory tax rate relates to the valuation allowances on the Company’s net operating losses and foreign tax rate differences. The "Provision for income tax expense" in the Consolidated Statements of Operations primarily consists of income and withholding taxes for foreign and state jurisdictions where the Company has profitable operations, as well as valuation allowance adjustments for certain U.S. tax jurisdictions. No tax benefit was provided for losses incurred in the U.S., Ireland and Singapore because those losses are offset by a full valuation allowance. The tax years 2012 through 2020 generally remain subject to examination by federal, state and foreign tax authorities. The gross amount of the Company’s unrecognized tax benefits was $1.0 million as of March 31, 2021 and December 31, 2020, none of which, if recognized, would affect the Company’s effective tax rate. The Company does not expect its unrecognized tax benefits to change significantly over the next 12 months. The Company recognizes interest and penalties accrued related to unrecognized tax benefits in income tax expense. During the three months ended March 31, 2021 and 2020, interest and penalties recognized were insignificant.

Summary of Significant Accoun_2

Summary of Significant Accounting Policies (Policies)	3 Months Ended
	Mar. 31, 2021
Accounting Policies [Abstract]
Basis of Presentation	Basis of PresentationThe accompanying unaudited interim Consolidated Financial Statements include the accounts of ServiceSource International, Inc. and its wholly owned subsidiaries and have been prepared in accordance with GAAP and with the instructions to Form 10-Q and Article 8 of Regulation S-X for interim financial information. All intercompany balances and transactions have been eliminated in consolidation. These financial statements do not include all the information required by GAAP for annual financial statements. The unaudited Consolidated Balance Sheet as of December 31, 2020 has been derived from the Company’s audited annual Consolidated Financial Statements included in our annual report on Form 10-K for the year ended December 31, 2020 filed with the SEC on February 24, 2021. In the opinion of management, these Consolidated Financial Statements reflect all adjustments, including normal recurring adjustments, management considers necessary for a fair presentation of the Company’s financial position, operating results, and cash flows for the interim periods presented. These Consolidated Financial Statements and accompanying notes should be read in conjunction with our audited Consolidated Financial Statements and the notes thereto for the year ended December 31, 2020, included in our annual report on Form 10-K. Interim results are not necessarily indicative of results for the entire year.
Use of Estimates	Use of Estimates The preparation of the Consolidated Financial Statements in accordance with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the Consolidated Financial Statements and the reported amount of net revenue and expenses during the reporting period. The Company bases its estimates and judgments on historical experience and on various assumptions that it believes are reasonable under the circumstances. The Company has considered the effects of the COVID-19 pandemic in determining its estimates. However, future events are difficult to predict and subject to change, especially with the risks and uncertainties related to the impact of the COVID-19 pandemic, which could cause estimates and judgments to require adjustment. Actual results and outcomes may differ from our estimates.
Cash Equivalents and Restricted Cash	Cash Equivalents and Restricted Cash The Company follows a three-tier fair value hierarchy, which is described in detail in the Company's Annual Report on Form 10-K for the year ended December 31, 2020. Cash equivalents consist of highly liquid investments with original maturities of three months or less at the time of purchase and are classified as a Level 1 investment. Restricted cash consists of cash in money market accounts that are used to secure letters of credit in connection with two of our leased facilities. Restricted cash is recorded within "Other assets" in the Consolidated Balance Sheets and is classified as a Level 1 investment. The Company had restricted cash of $2.3 million as of March 31, 2021 and December 31, 2020.
Government Assistance	Government AssistanceDuring 2020, ServiceSource received various grants from the Singapore government, including the Job Support Scheme, which assists enterprises in retaining their local employees during the COVID-19 pandemic. ServiceSource received $1.3 million related to these grants during the year ended December 31, 2020 and is expected to receive an additional $0.2 million through August 2021. There are no conditions to repay the grants. Government grants are recognized in the Company's Consolidated Statements of Operations during the same period that the expenses related to the grant are incurred if there is reasonable assurance the grant will be received, and the Company has complied with any conditions attached to the grant.
New Accounting Standards Adopted And New Accounting Standards Issued But Not Yet Adopted	New Accounting Standards Adopted Income Taxes In December 2019, the FASB issued an ASU that simplifies the accounting for income taxes by eliminating certain exceptions to the guidance in ASC 740 related to the approach for intraperiod tax allocation, the methodology for calculating income taxes in an interim period and the recognition of deferred tax liabilities for outside basis differences. This ASU is effective for annual periods and interim periods for those annual periods beginning after December 15, 2020, with early adoption permitted. The Company adopted this standard effective January 1, 2021 and the effects of this standard were applied prospectively to eligible costs incurred on or after January 1, 2021. The adoption of this standard did not have a material impact on the Consolidated Financial Statements. New Accounting Standards Issued but Not yet Adopted Financial Instruments - Credit Losses In June 2016, the FASB issued an ASU that amends the measurement of credit losses on financial instruments and requires measurement and recognition of expected versus incurred credit losses for financial assets held. This ASU is effective for annual periods and interim periods for those annual periods beginning after December 15, 2022, with early adoption permitted. This standard will apply to the Company's accounts receivable and contract assets. Based on our current analysis, the Company does not expect the adoption to have a material impact on the Consolidated Financial Statements as credit losses from trade receivables have historically been insignificant. The Company will adopt this standard effective January 1, 2023.
