Organization, Consolidation and Presentation of Financial Statements [Abstract]
Description of Business	Description of Business CommerceHub, Inc. (together with its subsidiaries, "CommerceHub," the "Company," "us," "we" and "our") was founded in 1997 (as Commerce Technologies, Inc., our predecessor entity) and is headquartered in Albany, New York, with additional locations in Seattle, Washington and Hertford, England. We are a leading provider of cloud-based ecommerce fulfillment and marketing solutions that integrate supply, demand and delivery for large retailers and consumer brands, manufacturers and distributors (collectively, "suppliers"). Our end-to-end solutions are provided through the CommerceHub software platform, a hub that streamlines integration and enables more efficient transactions among our retailer and supplier customers and their other trading partners, while also enabling them to access the online marketplaces, search engines, social and product advertising and other digital marketing channels where consumers browse and buy. Our solutions also help our customers integrate with the third-party logistics providers, including fulfillment and delivery providers, that take purchased products to the consumer's doorstep. During November 2015, the board of directors of Liberty Interactive Corporation, our former parent company ("Liberty" or "Parent"), authorized a plan to distribute to the holders of Liberty's Series A and Series B Liberty Ventures common stock, shares of CommerceHub (the "Spin-Off"). At the time, CommerceHub was a newly formed Delaware corporation that, pursuant to an internal restructuring, effective July 21, 2016, became the parent of Commerce Technologies, LLC, a Delaware limited liability company that, as a result of the restructuring, is the successor to Commerce Technologies, Inc. ("CTI"), the entity through which CommerceHub transacted prior to the Spin-Off. The Spin-Off was completed on July 22, 2016 and was effected as a pro rata dividend of shares of CommerceHub to the holders of Series A and Series B Liberty Ventures common stock of Liberty. The Internal Revenue Service has completed its review of the Spin-Off and has notified Liberty that it agreed with the nontaxable characterization of the Spin-Off. Following the Spin-Off, CommerceHub now operates as a stand-alone publicly traded company, and neither Liberty nor CommerceHub has any stock ownership, beneficial or otherwise, in the other.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	Basis of Presentation The accompanying unaudited condensed consolidated financial statements include the accounts of CommerceHub. All intercompany accounts and transactions have been eliminated in the condensed consolidated financial statements, which have been prepared in conformity with U.S. generally accepted accounting principles ("GAAP") for interim financial information. Accordingly, these condensed consolidated financial statements do not include all of the information and notes required by GAAP. We have included all normal recurring adjustments we consider to be necessary to give a fair presentation of our financial position, results of comprehensive income and cash flows, and changes in equity for the interim periods shown. Operating results for these interim periods are not necessarily indicative of the results to be expected for the full year. The December 31, 2016 consolidated balance sheet data was derived from our audited consolidated financial statements at that date. These condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements contained within our Annual Report on Form 10-K for the fiscal year ended December 31, 2016, which was filed with the Securities and Exchange Commission (the "SEC") on March 7, 2017 (the "2016 Annual Report"). Use of Estimates Preparing these condensed consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the condensed consolidated financial statements and the reported amounts of revenue and expenses during the reporting periods. Actual results could differ from those estimates and assumptions. Segment and Geographic Information Operating segments are components of our business for which discrete financial information is available and evaluated by the chief operating decision maker ("CODM") for purposes of allocating resources and evaluating financial performance. Our Chief Executive Officer, who is our CODM, reviews consolidated financial information results of the Company to allocate resources and evaluate performance. As such, the Company operates as a single segment. The following table summarizes revenue by type: (amounts in thousands) Three Months Ended Six Months Ended 2017 2016 2017 2016 Revenue: Usage revenue $ 16,553 $ 15,333 $ 32,412 $ 29,875 Subscription revenue 6,943 6,228 13,840 12,346 Set-up and professional services 1,712 1,542 3,524 2,972 Total revenue $ 25,208 $ 23,103 $ 49,776 $ 45,193 We generate nearly all of our revenue in the United States and Canada. For the six months ended June 30, 2017 and 2016 , approximately 96% of our revenue was generated from customers located in the United States. Substantially all of our assets are located within the United States.

Accounting Changes and Error Corrections [Abstract]
Recent Accounting Pronouncements	Recent Accounting Pronouncements In May 2014, the Financial Accounting Standards Board (the "FASB") issued Accounting Standards Update ("ASU") No. 2014-09, Revenue from Contracts with Customers (Topic 606) ("ASU No. 2014-09"). This standard is effective for fiscal years beginning after December 15, 2017, with two transition methods of adoption allowed, a full retrospective or modified retrospective. In May 2016, FASB issued ASU No. 2016-08, Revenue from Contracts with Customers (Topic 606): Principal versus Agent Considerations (Reporting Revenue Gross versus Net) . This update was to further clarify the implementation guidance on principal versus agent considerations in the previously issued ASU No. 2014-09. In April 2016, the FASB issued ASU No. 2016-10, Identifying Performance Obligations and Licensing , which clarifies implementation guidance on the identification of performance obligations and the licensing implementation guidance in ASU No. 2014-09. In May 2016, the FASB issued ASU No. 2016-12, Narrow-Scope Improvements and Practical Expedients , which clarifies the guidance on assessing collectability, presentation of sales taxes, non-cash consideration and completed contracts and contract modifications at transition. In December 2016, the FASB issued ASU No. 2016-20, Technical Corrections and Improvements to Topic 606 , which clarifies certain narrow aspects of ASU No. 2014-09. We continue to evaluate the impacts of this new standard on our business processes, information technology systems and associated internal controls. We have developed an implementation plan to adopt this standard, and, as part of this plan, we continue to assess the impacts this standard is expected to have on our financial statements and related disclosures, including the potential impacts to our usage, subscription and set-up and professional services revenue. We plan to adopt this standard using the modified retrospective transition method effective January 1, 2018. Although we are still evaluating the impact of this standard, based on our initial assessment we do not believe our adoption of this standard will significantly impact our recognition of our usage and subscription revenues. However, we believe our adoption of this standard could impact our accounting for certain set-up and professional services revenues and the periods over which these revenues and the related deferred services costs are recognized. Further, based on our initial assessment, we expect this standard will impact how we account for costs to acquire a contract. We expect that applying this standard will result in the deferral of additional costs, primarily commission expenses to sales representatives, which we expect to recognize over the estimated customer life. Due to the preliminary nature of our assessments to date and subject to our planned ongoing evaluations, we are currently unable to estimate the overall impact this standard will have on our financial statements. In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842) ("ASU No. 2016-02"). This topic provides that a lessee should recognize the assets and liabilities that arise from leases. ASU No. 2016-02 requires an entity to separate the lease components from the nonlease components in a contract. ASU No. 2016-02 is intended to improve financial reporting about lease transactions and is effective for fiscal years beginning after December 15, 2018. We are evaluating the impact this update will have on our financial statements. In March 2016, the FASB issued ASU No. 2016-09, Improvements to Employee Share-Based Payment Accounting ("ASU No. 2016-09"), which is intended to improve the accounting for share-based payment transactions as part of the FASB's simplification initiative. ASU No. 2016-09 changed aspects of the accounting for share-based payment award transactions, including: (1) accounting for income taxes; (2) classification of excess tax benefits on the statement of cash flows; (3) forfeitures; (4) minimum statutory tax withholding requirements; and (5) classification of employee taxes paid on the statement of cash flows when an employer withholds shares for tax-withholding purposes. Further, under ASU No. 2016-09 the calculation for diluted shares under the treasury-stock method no longer includes the effect of excess tax deductions, resulting in a higher effect of dilutive shares. We adopted ASU No. 2016-09 in the first quarter of 2017, which did not have a significant impact on our financial statements. In August 2016, the FASB issued ASU No. 2016-15, Classification of Certain Cash Receipts and Cash Payments (Topic 230) ("ASU No. 2016-15") , which addresses eight specific cash flow matters with the objective of reducing diversity in practice in how certain cash receipts and cash payments are classified in the statement of cash flows. ASU No. 2016-15 is effective for fiscal years beginning after December 15, 2017. We are evaluating the impact this update will have on our financial statements. In November 2016, the FASB issued ASU No. 2016-18, Restricted Cash ("ASU No. 2016-18") , which requires that entities show the changes in the total of cash, cash equivalents and restricted cash in the statement of cash flows. Transfers between cash, cash equivalents and restricted cash should not be presented as cash flow activities on the statement of cash flows. ASU No. 2016-18 is effective for fiscal years beginning after December 15, 2017. We do not expect the adoption of this standard will have a material impact on our financial statements. In January 2017, the FASB issued ASU No. 2017-04, Intangibles - Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment ("ASU No. 2017-04"), which removes Step 2 of the goodwill impairment test, which requires a hypothetical purchase price allocation. An impairment charge will now equal the amount by which the reporting unit's carrying value exceeds its fair value. ASU No. 2017-04 is effective for fiscal years beginning after December 15, 2019. We do not expect the adoption of this standard will have a material impact on our financial statements. In May 2017, the FASB issued ASU No. 2017-09, Compensation-Stock Compensation (Topic 718): Scope of Modification Accounting ("ASU No. 2017-09"), which clarifies what constitutes a modification of a share-based payment award. ASU No. 2017-09 is effective for fiscal years beginning after December 15, 2017. We do not expect the adoption of this standard will have a material impact on our financial statements.

Earnings Per Share

Earnings Per Share [Abstract]
Earnings Per Share	Earnings Per Share For the three and six months ended June 30, 2016 , basic and diluted earnings per common share is computed by dividing net income for that period by 42,702,842 common shares, which is the aggregate of 13,522,288 shares of Series A common stock, 711,992 shares Series B common stock and 28,468,562 shares of Series C common stock issued upon completion of the Spin-Off on July 22, 2016 . The shares used in the calculation of diluted earnings per share for periods prior to the Spin-Off exclude issuances of 109,354 shares of common stock issued to pre-Spin-Off minority shareholders of CTI and 7,362,933 outstanding awards to purchase shares of our common stock, which occurred after the Spin-Off. For the three and six months ended June 30, 2017 , basic earnings per common share is computed by dividing net income by the weighted average number of common shares outstanding during that period. Diluted earnings per share gives effect to all dilutive potential shares outstanding resulting from stock options and restricted stock units during that period. The shares used in the calculation of diluted earnings per share for periods following the Spin-Off exclude (a) options to purchase shares where the exercise price was greater than the average market price of common shares for the period, using the treasury-stock method, and therefore the effect of the inclusion would be anti-dilutive and (b) awards with performance-based conditions where the performance criteria has not been met as of the reporting date. The following table sets forth net income and the basic and diluted shares used to calculate earnings per share (in thousands): Three Months Ended Six Months Ended 2017 2016 2017 2016 Net income $ 2,245 $ 4,424 $ 4,704 $ 2,434 Basic - weighted average shares outstanding 43,155 42,703 43,068 42,703 Effect of dilutive potential securities 1,802 — 1,774 — Diluted - weighted average shares outstanding 44,957 42,703 44,842 42,703 Anti-dilutive securities 4,392 — 4,445 —

Risks and Uncertainties [Abstract]
Concentrations of Significant Customers and Credit Risk	Concentrations of Significant Customers and Credit Risk No single customer accounted for more than 10% of our total revenue in the six months ended June 30, 2017 or 2016 . However, our revenue model is primarily based on retailer and supplier program relationships whereby many revenue-generating supplier transactions conducted through our platform may be attributable to a single retailer ("Total Program Revenue"). For the six months ended June 30, 2017 and 2016 , one customer's Total Program Revenue accounted for more than 10% of total revenue. No single customer represented more than 10% of accounts receivable at June 30, 2017 .

Related Party Transactions [Abstract]
Related Party Transactions	Related Party Transactions Prior to the Spin-Off, Liberty, QVC, Inc. (“QVC”), which is a wholly owned subsidiary of Liberty, and other subsidiaries and equity investments of Liberty were related parties of CommerceHub for GAAP purposes and related persons of CommerceHub for purposes of Regulation S-K under the Securities Exchange Act of 1934, as amended. As a result, because this report includes the three and six months ended June 30, 2016 , which was prior to the Spin-Off, we have disclosed activities with these entities during this period. For the three and six months ended June 30, 2017 and future periods that do not include pre-Spin-Off periods, based on current facts and circumstances, we do not believe Liberty, QVC or other subsidiaries or equity investments of Liberty are related parties or related persons of CommerceHub, but we will continue to monitor and evaluate these relationships and other potential relationships with related parties and/or related persons. Transactions with QVC We provide our solutions to QVC in the ordinary course of business. For the six months ended June 30, 2016 , Total Program Revenue with QVC accounted for approximately 7% of total revenue. We had accounts receivable due from QVC of approximately $784 thousand at December 31, 2016 . Transactions with Liberty In previous periods, we had outstanding a promissory note as a lender to Liberty, presented as note receivable—Parent on the consolidated balance sheets. This note carried an interest rate based on one-year LIBOR plus 100 basis points . In the three and six months ended June 30, 2016 , we earned interest of $107 thousand and $273 thousand , respectively, on this promissory note. During the second quarter of 2016, Liberty fully repaid the $36.4 million outstanding under this promissory note, including accumulated interest of $2.4 million. During June 2016, we entered into a funding arrangement with Liberty pursuant to a previously established intercompany funding agreement. Under this arrangement, Liberty agreed to loan us $28.7 million , at current market interest rates, so we could fulfill our obligations under the predecessor plan to the CommerceHub, Inc. Legacy Stock Appreciation Rights Plan and our related liquidity program. In July 2016, we fully repaid amounts outstanding pursuant to this arrangement, including accumulated interest, to Liberty using borrowings under our credit facility, and the funding agreement between us and Liberty was terminated as of the completion of the Spin-Off.

Share-Based Awards

Disclosure of Compensation Related Costs, Share-based Payments [Abstract]
Share-Based Awards	Share-Based Awards We grant equity incentive awards to certain of our employees (including our executive officers), directors and consultants. Following the Spin-Off, all of the awards we have granted have been stock options and restricted stock units ("RSUs") relating to shares of our Series C common stock. Some of these awards contain service-based vesting conditions (typically annual vesting over four years), and some of these awards contain both service- and milestone-based vesting conditions. We estimate the fair value of the stock options granted using the Black-Scholes pricing model. In valuing share-based awards, significant judgment is required in determining the fair value of our share price, the expected volatility of common stock, and the expected term individuals will hold their share-based awards prior to exercise. With the assistance of an independent third-party advisory firm, for awards granted during the three months ended March 31, 2016, we estimated share-price based on an internal valuation using income- and market-based approaches. For the three months ended June 30, 2016, the estimated share-price input was based on the market value of CommerceHub's Series C common stock traded immediately following the Spin-Off. In connection with the Spin-Off, the awards outstanding were modified, and their respective fair values were updated at the Spin-Off. The share-price input at the Spin-Off was based on the closing share price the first trading day following the Spin-Off. Included in the condensed consolidated statements of comprehensive income are the following amounts of share-based compensation (amounts in thousands): Three Months Ended Six Months Ended 2017 2016 2017 2016 Cost of revenue $ 89 $ (662 ) $ 199 $ (158 ) Research and development 530 (747 ) 1,101 1,113 Sales and marketing 300 (383 ) 435 601 General and administrative 1,698 (1,685 ) 3,242 5,004 $ 2,617 $ (3,477 ) $ 4,977 $ 6,560 Prior to the Spin-Off, awards outstanding were liability-based awards as they could be settled in cash, and they were marked-to-market each reporting period based on an internal valuation as described above. For periods following the Spin-Off, all awards are equity-based awards and can no longer be settled in cash, and these equity-based awards are not marked-to-market each reporting period. For the three months ended June 30, 2016, the estimated share-price input was based on the market value of CommerceHub's Series C common stock traded immediately following the Spin-Off, which decreased as compared to our latest internal valuation prior to the Spin-Off and resulted in a reduction to share-based compensation expense in that period as compared to the 2017 period, during which our awards are no longer marked-to-market. For the six months ended June 30, 2016, the share-price input was based on internal valuations as described above, which resulted in higher share-based compensation expense in that period as compared to the 2017 period, during which our awards are no longer marked-to-market. CommerceHub Share-Based Award Plans In connection with the Spin-Off, all of the outstanding CTI stock appreciation rights and stock options were converted into new option awards to purchase shares of our Series C common stock, which were issued under the CommerceHub, Inc. Legacy Stock Appreciation Rights Plan and the CommerceHub, Inc. Legacy Stock Option Plan (together, the "Legacy Plans"), respectively. The Legacy Plans govern the terms and conditions of these new option awards but will not be used to make any further grants. In connection with the Spin-Off, we also adopted the CommerceHub, Inc. 2016 Omnibus Incentive Plan (as amended, amended and restated or otherwise modified from time to time, the “Omnibus Plan”), which is the incentive plan we use for all new equity grants following the Spin-Off. On January 1, 2017, the number of shares available for issuance under the Omnibus Plan was increased by 2,146,064 shares, or 5% of the outstanding shares of our common stock on December 31, 2016, to 15,346,064 shares. On June 16, 2017, our public stockholders approved the Second Amended and Restated Omnibus Plan at our 2017 Annual Meeting of Stockholders. In addition, also in connection with the Spin-Off, we adopted an Employee Stock Purchase Plan (the “ESPP”), which provides employees with the opportunity to invest a portion of their annual eligible compensation to purchase shares of our Series C common stock at a purchase price equal to 85% of the lower of (a) the fair market value of our Series C common stock at the beginning of the applicable six-month offering period, and (b) the fair market value of our Series C common stock at the end of the applicable six-month offering period. The first offering period under the ESPP began on January 1, 2017. For the six months ended June 30, 2017 , we recorded approximately $160 thousand of share-based compensation expense associated with the ESPP. The fair value of ESPP shares is estimated based on the market price of our Series C common stock at the beginning of each offering period and the Black-Scholes option pricing model with the following assumptions: Volatility 41.5 % Term (in years) 0.5 Risk-free interest rate 0.8 % Dividend yield — % Also in connection with the Spin-Off, holders of option awards, RSUs and restricted stock awards ("RSAs") relating to Liberty's Liberty Ventures common stock received CommerceHub options, RSUs and RSAs, respectively, pursuant to the CommerceHub, Inc. Transitional Stock Adjustment Plan (the “Transitional Plan”). The Transitional Plan, which is administered for the benefit of Liberty employees and consultants, governs the terms and conditions of these new awards but will not be used to make any further grants. The following table summarizes the share-based award activity of options to purchase shares of our common stock for the six months ended June 30, 2017 : CommerceHub Employee Plans Liberty Employee Plans Omnibus Plan Legacy Plans Transitional Plan Series C Series C Series C Series A Outstanding at January 1, 2017 193,998 5,580,109 1,006,043 329,188 Granted 350,820 — — — Exercised — (70,888 ) (121,707 ) (60,870 ) Forfeited (17,590 ) (86,310 ) (3,558 ) (1,785 ) Outstanding at June 30, 2017 527,228 5,422,911 880,778 266,533 Weighted average exercise price $ 15.76 $ 13.01 $ 9.41 $ 7.90 Weighted average remaining contractual life (in years) 9.6 7.7 3.9 3.5 Aggregate intrinsic value (in thousands) $ 883 $ 24,017 $ 7,072 $ 2,524 Exercisable at June 30, 2017 5,000 1,950,479 474,089 203,328 Weighted average exercise price $ 14.99 $ 7.71 $ 7.23 $ 6.45 Weighted average remaining contractual life (in years) 9.5 5.6 3.1 2.8 Aggregate intrinsic value (in thousands) $ 12 $ 18,987 $ 4,843 $ 2,218 The weighted average grant-date fair value of options granted during the six months ended June 30, 2017 was $7.30 . As of June 30, 2017 , unrecognized compensation cost related to options to purchase shares of our Series C common stock under the Omnibus Plan and Legacy Plans was approximately $15.5 million and is expected to be recognized over a weighted average remaining vesting period of approximately 3.1 years . There is no unrecognized compensation cost related to options under the Transitional Plan because they are held by employees of Liberty and any related compensation expense is incurred by Liberty. RSU Activity Under the Omnibus Plan (Series C) The following table summarizes the share-based award activity of RSUs relating to our Series C common stock granted under the Omnibus Plan for the six months ended June 30, 2017 : Number of Weighted Outstanding at January 1, 2017 505,831 $ 14.35 Granted 380,787 $ 16.59 Vested (47,106 ) $ 14.33 Forfeited (70,384 ) $ 14.42 Outstanding at June 30, 2017 769,128 $ 15.46 As of June 30, 2017 , unrecognized compensation cost related to RSUs relating to shares of our Series C common stock was approximately $7.3 million and is expected to be recognized over a weighted average remaining vesting period of approximately 3.5 years . RSA and RSU Activity Under the Transitional Plan (Series A and Series C) Share-based award activity for RSUs and RSAs relating to our Series A and Series C common stock issued under the Transitional Plan for the six months ended June 30, 2017 was not material. There is no unrecognized compensation cost related to these awards because they are held by employees of Liberty and any related compensation expense is incurred by Liberty. Options and RSA Activity Under the Transitional Plan (Series B) For the six months ended June 30, 2017 , there was no activity in the outstanding stock options relating to our Series B common stock, and share-based award activity for RSAs relating to our Series B common stock was not material. There is no unrecognized compensation cost related to these awards because they are held by an employee of Liberty and any related compensation expense is incurred by Liberty.

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes Our expense from income taxes for interim periods is determined using an estimate of our annual effective tax rate, adjusted for discrete items. During the three months ended June 30, 2017 and 2016 , our effective tax rate was 38% and 40% , respectively, which was higher than the U.S. Federal income tax rate of 35% , primarily due to state and local income tax, net of Federal income tax benefits, offset by the Federal research credit. During the six months ended June 30, 2017 and 2016 , our effective tax rate was 39% and 46% , respectively. For the six months ended June 30, 2017 , our effective tax rate was higher than the U.S. Federal income tax rate of 35% , primarily due to state and local income tax, net of Federal income tax benefits, offset by the Federal research credit. For the six months ended June 30, 2016 , our effective tax rate was higher than the 35% Federal income tax rate, primarily due to the effect of market adjustments for stock options exercised under our share-based compensation program, non-deductible transaction-related costs incurred in 2016 associated with the Spin-Off, and the Federal research credit. There were no uncertain tax positions as of June 30, 2017 or December 31, 2016.

Debt Disclosure [Abstract]
Long-Term Debt	Long-Term Debt On June 28, 2016, we entered into a credit agreement governing a $125.0 million revolving credit facility, which expires on June 28, 2021. At June 30, 2017 , we had $6.0 million in borrowings and no letters of credit outstanding under the facility, and our available borrowings under the facility were $119.0 million . Subsequent to June 30, 2017 , we repaid an additional $2.0 million in borrowings under the facility. At June 30, 2017 , the fair value of our debt, which holds a floating interest rate of a short duration and is based on Level 2 valuation inputs, approximated the carrying value. The interest rate applicable to our initial borrowings is LIBOR plus a yield of 1.75% . Interest on the revolving credit facility is based on a base rate or Eurodollar rate plus an applicable margin that increases as our total leverage ratio increases, with the base rate margin ranging from 0.75% to 1.25% and the Eurodollar rate margin ranging from 1.75% to 2.25% . The revolving credit facility also carries a commitment fee of 0.25% to 0.50% per annum on the unused portion. Borrowings under the revolving credit facility are collateralized by substantially all of our assets. The credit agreement contains covenants and restrictions which, among other things, require the maintenance of certain financial ratios, including a total leverage ratio and an interest coverage ratio, and restrict dividend payments and the incurrence of certain indebtedness and other activities, including acquisitions and dispositions. We were in compliance with these covenants and restrictions as of June 30, 2017 .

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies Legal Proceedings From time to time, we may become involved in various lawsuits and legal proceedings which arise in the ordinary course of business. We are currently not aware of any such legal proceedings or claims that we believe will have, individually or in the aggregate, a material adverse effect on our business, prospects, financial condition results of operations and/or cash flows. Leases During the first quarter of 2017, we entered into a new lease for office space in Seattle, Washington and, at the same time, entered into a sub-lease of our existing space in Seattle. We vacated our previous office and moved into the new office space in the second quarter of 2017 and, as a result, recognized an impairment charge equal to the fair value of the unrecovered payments for the remainder of the lease, which was not material. Future minimum lease payments due under operating lease arrangements contain rent increases over the term of the lease. Rent expense on these operating leases is recognized over the term of the lease on a straight-line basis. The excess of rent expense over future minimum lease payments due totaled $2.0 million and $1.1 million at June 30, 2017 and December 31, 2016 , respectively, and are included in other long-term liabilities on the condensed consolidated balance sheets. At June 30, 2017 , future minimum payments under operating leases, net of expected lease collections under our sub-lease, were as follows (in thousands): Remainder of 2017 $ 1,013 2018 2,032 2019 1,581 2020 1,563 2021 1,597 $ 7,786

Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The accompanying unaudited condensed consolidated financial statements include the accounts of CommerceHub. All intercompany accounts and transactions have been eliminated in the condensed consolidated financial statements, which have been prepared in conformity with U.S. generally accepted accounting principles ("GAAP") for interim financial information. Accordingly, these condensed consolidated financial statements do not include all of the information and notes required by GAAP. We have included all normal recurring adjustments we consider to be necessary to give a fair presentation of our financial position, results of comprehensive income and cash flows, and changes in equity for the interim periods shown. Operating results for these interim periods are not necessarily indicative of the results to be expected for the full year. The December 31, 2016 consolidated balance sheet data was derived from our audited consolidated financial statements at that date. These condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements contained within our Annual Report on Form 10-K for the fiscal year ended December 31, 2016, which was filed with the Securities and Exchange Commission (the "SEC") on March 7, 2017 (the "2016 Annual Report").
Use of Estimates	Use of Estimates Preparing these condensed consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the condensed consolidated financial statements and the reported amounts of revenue and expenses during the reporting periods. Actual results could differ from those estimates and assumptions.
Recent Accounting Pronouncements	Recent Accounting Pronouncements In May 2014, the Financial Accounting Standards Board (the "FASB") issued Accounting Standards Update ("ASU") No. 2014-09, Revenue from Contracts with Customers (Topic 606) ("ASU No. 2014-09"). This standard is effective for fiscal years beginning after December 15, 2017, with two transition methods of adoption allowed, a full retrospective or modified retrospective. In May 2016, FASB issued ASU No. 2016-08, Revenue from Contracts with Customers (Topic 606): Principal versus Agent Considerations (Reporting Revenue Gross versus Net) . This update was to further clarify the implementation guidance on principal versus agent considerations in the previously issued ASU No. 2014-09. In April 2016, the FASB issued ASU No. 2016-10, Identifying Performance Obligations and Licensing , which clarifies implementation guidance on the identification of performance obligations and the licensing implementation guidance in ASU No. 2014-09. In May 2016, the FASB issued ASU No. 2016-12, Narrow-Scope Improvements and Practical Expedients , which clarifies the guidance on assessing collectability, presentation of sales taxes, non-cash consideration and completed contracts and contract modifications at transition. In December 2016, the FASB issued ASU No. 2016-20, Technical Corrections and Improvements to Topic 606 , which clarifies certain narrow aspects of ASU No. 2014-09. We continue to evaluate the impacts of this new standard on our business processes, information technology systems and associated internal controls. We have developed an implementation plan to adopt this standard, and, as part of this plan, we continue to assess the impacts this standard is expected to have on our financial statements and related disclosures, including the potential impacts to our usage, subscription and set-up and professional services revenue. We plan to adopt this standard using the modified retrospective transition method effective January 1, 2018. Although we are still evaluating the impact of this standard, based on our initial assessment we do not believe our adoption of this standard will significantly impact our recognition of our usage and subscription revenues. However, we believe our adoption of this standard could impact our accounting for certain set-up and professional services revenues and the periods over which these revenues and the related deferred services costs are recognized. Further, based on our initial assessment, we expect this standard will impact how we account for costs to acquire a contract. We expect that applying this standard will result in the deferral of additional costs, primarily commission expenses to sales representatives, which we expect to recognize over the estimated customer life. Due to the preliminary nature of our assessments to date and subject to our planned ongoing evaluations, we are currently unable to estimate the overall impact this standard will have on our financial statements. In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842) ("ASU No. 2016-02"). This topic provides that a lessee should recognize the assets and liabilities that arise from leases. ASU No. 2016-02 requires an entity to separate the lease components from the nonlease components in a contract. ASU No. 2016-02 is intended to improve financial reporting about lease transactions and is effective for fiscal years beginning after December 15, 2018. We are evaluating the impact this update will have on our financial statements. In March 2016, the FASB issued ASU No. 2016-09, Improvements to Employee Share-Based Payment Accounting ("ASU No. 2016-09"), which is intended to improve the accounting for share-based payment transactions as part of the FASB's simplification initiative. ASU No. 2016-09 changed aspects of the accounting for share-based payment award transactions, including: (1) accounting for income taxes; (2) classification of excess tax benefits on the statement of cash flows; (3) forfeitures; (4) minimum statutory tax withholding requirements; and (5) classification of employee taxes paid on the statement of cash flows when an employer withholds shares for tax-withholding purposes. Further, under ASU No. 2016-09 the calculation for diluted shares under the treasury-stock method no longer includes the effect of excess tax deductions, resulting in a higher effect of dilutive shares. We adopted ASU No. 2016-09 in the first quarter of 2017, which did not have a significant impact on our financial statements. In August 2016, the FASB issued ASU No. 2016-15, Classification of Certain Cash Receipts and Cash Payments (Topic 230) ("ASU No. 2016-15") , which addresses eight specific cash flow matters with the objective of reducing diversity in practice in how certain cash receipts and cash payments are classified in the statement of cash flows. ASU No. 2016-15 is effective for fiscal years beginning after December 15, 2017. We are evaluating the impact this update will have on our financial statements. In November 2016, the FASB issued ASU No. 2016-18, Restricted Cash ("ASU No. 2016-18") , which requires that entities show the changes in the total of cash, cash equivalents and restricted cash in the statement of cash flows. Transfers between cash, cash equivalents and restricted cash should not be presented as cash flow activities on the statement of cash flows. ASU No. 2016-18 is effective for fiscal years beginning after December 15, 2017. We do not expect the adoption of this standard will have a material impact on our financial statements. In January 2017, the FASB issued ASU No. 2017-04, Intangibles - Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment ("ASU No. 2017-04"), which removes Step 2 of the goodwill impairment test, which requires a hypothetical purchase price allocation. An impairment charge will now equal the amount by which the reporting unit's carrying value exceeds its fair value. ASU No. 2017-04 is effective for fiscal years beginning after December 15, 2019. We do not expect the adoption of this standard will have a material impact on our financial statements. In May 2017, the FASB issued ASU No. 2017-09, Compensation-Stock Compensation (Topic 718): Scope of Modification Accounting ("ASU No. 2017-09"), which clarifies what constitutes a modification of a share-based payment award. ASU No. 2017-09 is effective for fiscal years beginning after December 15, 2017. We do not expect the adoption of this standard will have a material impact on our financial statements.
