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, 2019 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, 2019 filed with the SEC on February 19, 2020 . 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, 2019 , 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. Reclassifications Certain items on the Consolidated Statements of Cash Flows for the six months ended June 30, 2019 have been reclassified to conform to the current year presentation. These reclassifications did not affect the Consolidated Balance Sheets, Consolidated Statements of Operations, Consolidated Statements of Comprehensive Loss or Consolidated Statements of Stockholders' Equity. Government Assistance During 2020, ServiceSource received a grant from the Singapore government pursuant to its Job Support Scheme, which assists enterprises in retaining their local employees during the COVID-19 pandemic. ServiceSource received approximately $0.4 million from the grant during the three and six months ended June 30, 2020 and is expected to receive an additional $0.7 million during the second half of 2020. 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 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. 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. Based on our current analysis, the Company does not expect the adoption to have a material impact on the Consolidated Financial Statements. The Company will adopt this standard effective January 1, 2021.

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 Borrowers named therein to borrow against its 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. During March 2020 , the Company borrowed $27.0 million under the Revolver through a six-month Eurodollar borrowing at an effective interest rate of 3.07% . As of June 30, 2020 , the Company repaid $7.0 million of the outstanding balance and converted the remaining $20.0 million of borrowings into a one-month Eurodollar borrowing at an effective interest rate of 2.18% maturing July 2020 . An additional $6.5 million was available for borrowing under the Revolver as of June 30, 2020 . The Eurodollar borrowings may be extended upon maturity, converted into a base rate borrowing upon maturity or require an incremental payment if our borrowing base decreases below our current amount outstanding during the term of the Eurodollar borrowing. Subsequent to June 30, 2020 , the one-month $20.0 million Eurodollar borrowing was extended at an effective interest rate of 2.17% maturing August 2020 . The obligations under the Credit Agreement are secured by substantially all of 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 June 30, 2020 and December 31, 2019 . Deferred Debt Issuance Costs and Interest Expense Unamortized debt issuance costs related to the Revolver were $0.1 million as of June 30, 2020 and December 31, 2019 . Interest expense related to the amortization of debt issuance costs and interest expense associated with the Company's debt obligation was $0.2 million and $0.04 million for the three months ended June 30, 2020 and 2019 , respectively and $0.3 million and $0.1 million for the six months ended June 30, 2020 and 2019 , respectively.

Leases [Abstract]
Leases	Leases The Company has operating leases for office space and finance leases for certain equipment under non-cancelable agreements with various expiration dates through May 2030. Certain office leases include the option to extend the term between one to seven years and certain office leases include the option to terminate the lease upon written notice within one to eight years after lease commencement. Leases with an initial term of 12 months or less are not recorded on the balance sheet. In January 2020, the Company entered into a one-year sublease agreement with a third-party for one floor of its Manila office space, with total sublease income of approximately $1.1 million .

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 June 30, 2020 and December 31, 2019 , 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 and six months ended June 30, 2020 and 2019 , interest and penalties recognized were insignificant.

Accounting Policies [Abstract]
Basis of Presentation	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, 2019 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, 2019 filed with the SEC on February 19, 2020 . 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, 2019
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.
Reclassifications	Reclassifications Certain items on the Consolidated Statements of Cash Flows for the six months ended June 30, 2019 have been reclassified to conform to the current year presentation. These reclassifications did not affect the Consolidated Balance Sheets, Consolidated Statements of Operations, Consolidated Statements of Comprehensive Loss or Consolidated Statements of Stockholders' Equity.
Government Assistance	Government Assistance During 2020, ServiceSource received a grant from the Singapore government pursuant to its Job Support Scheme, which assists enterprises in retaining their local employees during the COVID-19 pandemic. ServiceSource received approximately $0.4 million from the grant during the three and six months ended June 30, 2020 and is expected to receive an additional $0.7 million
New Accounting Policy Related to Government Assistance and New Accounting Standards Issued but Not yet Adopted	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. 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. Based on our current analysis, the Company does not expect the adoption to have a material impact on the Consolidated Financial Statements. The Company will adopt this standard effective January 1, 2021.
