Accounting Policies [Abstract]
Summary of significant accounting policies	Summary of Significant Accounting Policies Basis of Presentation The Company’s unaudited condensed consolidated financial statements have been prepared in conformity with accounting principles generally accepted in the United States of America (“GAAP”) and applicable rules and regulations of the U.S. Securities and Exchange Commission (“SEC”) for quarterly reports on Form 10-Q and Article 10-1 of Regulation S-X. Accordingly, some information and footnote disclosures required by GAAP for complete financial statements have been condensed or omitted pursuant to such rules and regulations. In the opinion of the Company’s management, the accompanying unaudited condensed consolidated financial statements and notes have been prepared on the same basis as the audited consolidated financial statements for the year ended December 31, 2014 and include all adjustments (consisting of normal recurring adjustments) necessary for a fair statement of the interim periods presented. The condensed consolidated balance sheet at December 31, 2014 has been derived from the audited financial statements at that date, but does not include all of the disclosures required by GAAP. The accompanying condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and notes thereto contained in the Company’s Form 10-K filed with the SEC on March 12, 2015. Use of Estimates The preparation of consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the dates of the consolidated financial statements, and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Assets and liabilities which are subject to judgment and use of estimates include sales allowances and allowances for doubtful accounts, the fair value of assets and liabilities assumed in business combinations, fair value of the capitalized facility leases, the recoverability of goodwill and long-lived assets, valuation allowances with respect to deferred tax assets, useful lives associated with property and equipment and intangible assets, contingencies, and the valuation and assumptions underlying stock-based compensation and other equity instruments. On an ongoing basis, the Company evaluates its estimates compared to historical experience and trends, which form the basis for making judgments about the carrying value of assets and liabilities. In addition, the Company engaged valuation specialists to assist with management’s determination of the valuation of its capitalized facility leases, fair values of assets and liabilities assumed in business combinations, and in periods prior to the Company’s initial public offering, valuation of common stock. Segments The Company has one operating segment. The Company’s Chief Operating Decision Makers (“CODM”), the Chief Executive Officer and the Chief Financial Officer, manage the Company’s operations based on consolidated financial information for purposes of evaluating financial performance and allocating resources. The CODM review financial information on a consolidated basis, accompanied by information about transaction revenue and forecasts, consulting and other revenue (Note 13). All of the Company’s principal operations, decision-making functions and assets are located in the United States. Recent Accounting Pronouncements Under the Jumpstart Our Business Startups Act (“JOBS Act”), the Company meets the definition of an emerging growth company. The Company has irrevocably elected to opt out of the extended transition period for complying with new or revised accounting standards pursuant to Section 107(b) of the JOBS Act. In September 2015, the Financial Accounting Standards Board ("FASB") issued new guidance regarding business combinations to simplify measurement-period adjustments. Under this guidance, an acquirer must recognize adjustments to provisional amounts that are identified during the measurement period in the reporting period in which the adjustment amounts are determined. This guidance also requires acquirers to present separately on the face of the income statement, or disclose in the notes, the portion of the amount recorded in current period earnings by line item that would have been recorded in previous reporting periods. The new guidance is effective for annual and interim reporting periods beginning after December 15, 2015 and must be applied prospectively. The adoption of this guidance is not expected to have an impact on the Company’s consolidated financial statements. In April 2015, the FASB issued new guidance related to the presentation of debt issuance costs, which requires debt issuance costs to be presented in the balance sheet as a direct deduction for the associated debt liability. The new guidance is effective for annual and interim reporting periods beginning after December 15, 2015. Early adoption is permitted for financial statements that have not been previously issued. The adoption of this guidance is not expected to have an impact on the Company’s consolidated financial statements. In April 2015, the FASB issued new guidance related to the customer’s accounting for fees paid in a cloud computing arrangement, which provides guidance to customers about whether a cloud computing arrangement includes a software license. If a cloud computing arrangement includes a software license, then the customer should account for the software license element of the arrangement consistent with the acquisition of other software licenses. If a cloud computing arrangement does not include a software license, the customer should account for the arrangement as a service contract. The new guidance is effective for annual and interim reporting periods beginning after December 15, 2015. Early adoption is permitted. The adoption of this guidance is not expected to have an impact on the Company’s consolidated financial statements. In May 2014, the FASB issued guidance related to revenue from contracts with customers. Under this guidance, revenue is recognized when promised goods or services are transferred to customers in an amount that reflects the consideration that is expected to be received for those goods or services. The updated standard will replace all existing revenue recognition guidance under GAAP when it becomes effective and permits the use of either the retrospective or cumulative effect transition method. In August 2015, the FASB deferred the effective date to January 1, 2018, with early adoption beginning January 1, 2017. The Company is evaluating the impact of adopting this guidance on its consolidated financial statements.

Fair Value Measurements

Fair Value Disclosures [Abstract]
Fair value measurements	Fair Value Measurements Fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. Valuation techniques used to measure fair value must maximize the use of observable inputs and minimize the use of unobservable inputs. Accounting standards describe a fair value hierarchy based on three levels of inputs, of which the first two are considered observable and the last unobservable, that may be used to measure fair value which are the following: • Level 1 — Quoted prices in active markets for identical assets or liabilities or funds. • Level 2 — Inputs other than Level 1 that are observable, either directly or indirectly, such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities. • Level 3 — Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities. The carrying amounts of cash equivalents, accounts receivable, prepaid and other current assets, accounts payable, and accrued expenses and other current liabilities approximate fair value because of the short maturity of these items. The following table summarizes the Company’s financial assets measured at fair value on a recurring basis at September 30, 2015 and December 31, 2014 by level within the fair value hierarchy. Financial assets are classified in their entirety based on the lowest level of input that is significant to the fair value measurement (in thousands): At September 30, 2015 At December 31, 2014 Level 1 Total Fair Level 1 Total Fair Cash equivalents $ 122,979 $ 122,979 $ 145,284 $ 145,284 Total Assets $ 122,979 $ 122,979 $ 145,284 $ 145,284

Credit Facility

Debt Disclosure [Abstract]
Credit facility	Credit Facility The Company had previously entered into a credit facility with a financial institution that provided for advances under a formula-based revolving line of credit and had no amounts outstanding at December 31, 2014. In February 2015, the Company amended its credit facility and entered into a third amended and restated loan and security agreement (“Third Amended Credit Facility”) with the same financial institution, effective as of February 18, 2015, for a $35.0 million secured revolving credit facility that expires on February 18, 2018. The Third Amended Credit Facility provides a $10.0 million subfacility for the issuance of letters of credit and contains an increase option permitting the Company, subject to the lenders consent, to increase the revolving credit facility by up to $15.0 million , to an aggregate maximum of $50 million . The Third Amended Credit Facility bears interest, at the Company’s option, at either (i) the prime rate published by The Wall Street Journal, plus a spread of -0.25% to 0.50% , or (ii) a LIBOR rate determined in accordance with the terms of the Third Amended Credit Facility, plus a spread of 1.75% to 2.50% . In each case, the spread is based on the Company’s adjusted quick ratio, which is a ratio of the Company’s cash and cash equivalents plus net billed accounts receivable to current liabilities plus all borrowings under the credit facility. Interest is due and payable quarterly in arrears for prime rate loans and on the earlier of the last day of each quarter or the end of an interest period, as defined in the Third Amended Credit Facility, for LIBOR rate loans. The Company is also obligated to pay an unused revolving line facility fee of 0.0% to 0.20% per annum based on the Company’s adjusted quick ratio. Third Amended Credit Facility requires the Company to maintain an adjusted quick ratio of at least 1.5 to 1 on the last day of each quarter. If this adjusted quick ratio is not maintained, then the facility requires the Company to maintain, as measured at each quarter end, a maximum consolidated leverage ratio of 3.00 or 2.50 to 1.00 , and a fixed charge coverage ratio of at least 1.25 to 1.00 . Consolidated leverage ratio is a ratio of all funded indebtedness, including all capital lease obligations, plus all letters of credit under the facility to the Company’s Adjusted EBITDA for the trailing twelve months. Fixed charge coverage ratio is the ratio of our Adjusted EBITDA less cash paid for income taxes to our cash paid for interest plus capital expenditures for the trailing twelve months. This credit facility also limits the Company’s ability to pay dividends. At September 30, 2015 , the Company was in compliance with all financial covenants.

Commitments and Contingencies Disclosure [Abstract]
Commitments and contingencies	Commitments and Contingencies Office Lease Commitments At September 30, 2015 , the Company had various non-cancellable leases related to the Company’s office facilities which expire through 2030. The Company recorded rent expense of $1.2 million and $0.8 million for the three months ended September 30, 2015 and 2014 , respectively. For the nine months ended September 30, 2015 and 2014 , total rent expense was $3.2 million and $2.1 million , respectively. San Francisco Office Lease In May 2014, the Company entered into a new facility lease in San Francisco (the “San Francisco Office”) with total future minimum lease commitments over 10 years, beginning August 1, 2014, of $7.0 million . In connection with this lease, the Company was required to obtain an irrevocable standby letter of credit in the amount of $0.8 million for the benefit of the landlord. Beginning August 1, 2017 through August 1, 2020, the letter of credit is subject to an annual reduction to as little as $0.2 million . The Company concluded that it was deemed the owner (for accounting purposes only) of the San Francisco Office during the construction period under build-to-suit lease accounting. As the Company assumed control of the construction project in the third quarter of 2014, the Company recorded the fair value of the leased property in “Property and equipment, net” and a corresponding liability in “Lease financing obligations” on the accompanying consolidated balance sheets. The Company recognized increases in the asset as additional building costs were incurred during the construction period. Additionally, imputed interest during the construction period was capitalized. At September 30, 2015 and December 31, 2014 , the Company has capitalized $8.7 million and $6.6 million , respectively, in “Property and equipment, net” and a corresponding current and non-current lease financing obligation of $6.8 million and $6.6 million , respectively. Upon completion of the construction during the first quarter of 2015, the Company had retained the fair value of the lease property and the obligation on its balance sheet as it did not qualify for sales and leaseback accounting due to requirements to maintain collateral in the lease. The Company records the rent payments as a reduction of the lease financing obligation and imputed interest expense; ground rent will be recorded as an operating expense. The fair value of the lease property is being depreciated over the building’s estimated useful life of forty years. At the conclusion of the lease term, the Company will de-recognize both the then carrying values of the asset and financing obligation. Santa Monica Office Lease In July 2014, the Company entered into a new facility lease in Santa Monica (the “Santa Monica Office”) with total future minimum lease commitments over fifteen years, beginning in January 2015, of $36.0 million . In connection with this lease, the Company obtained an irrevocable standby letter of credit in the amount of $3.5 million for the benefit of the landlord. Beginning October 1, 2019 through October 1, 2025, the letter of credit is subject to an annual reduction to as little as $1.2 million . The Company has concluded that it is deemed the owner (for accounting purposes only) of the Santa Monica Office during the construction period under build-to-suit lease accounting. As the Company assumed control of the construction project in the first quarter of 2015, the Company recorded the fair value of the leased property in “Property and equipment, net” and a corresponding liability in “Lease financing obligations” on the accompanying consolidated balance sheets. The Company recognizes increases in the asset as additional building costs are incurred during the construction period. Additionally, imputed interest is capitalized during the construction period. At September 30, 2015 , the Company has capitalized $27.6 million in “Property and equipment, net” and a corresponding current and non-current lease financing obligation of $22.1 million . Upon completion of the construction, which is estimated to be completed in the fourth quarter of 2015, the Company will retain the fair value of the Santa Monica Office lease property and the obligation on its balance sheet as it does not qualify for sales leaseback accounting due to requirements to maintain collateral in the lease. The Company will record the rent payments as a reduction of the lease financing obligation and imputed interest expense; ground rent will be recorded as an operating lease. The fair value of the lease property will be depreciated over the building’s estimated useful life of forty years. At the conclusion of the lease term, the Company will de-recognize both the then carrying values of the asset and financing obligation. Other Lease Amendments and New Lease In February 2015, the Company amended an office lease for approximately 17,000 square feet in Santa Monica, California, to extend the lease term from June 2016 to December 2025. Additionally, beginning in 2016, the Company will lease approximately 21,000 additional square feet in the building through December 2025. The Company has the option to extend the lease term for portions of the space, or the entire space, for an additional five year period. The cumulative base rent over the lease term is expected to be approximately $26.0 million . In connection with the original lease for this space, the Company was required to obtain an irrevocable standby letter of credit, in the amount of $0.5 million for the benefit of its landlord. The current letter of credit expires June 30, 2016. In February 2015, the Company entered into a new five year office lease for approximately 6,000 square feet in Los Angeles, California which commenced in April 2015. The Company has the option to extend the lease for two additional five year periods. The cumulative base rent over the initial lease term is $3.0 million . Also in February 2015, the Company amended an office lease for approximately 5,000 square feet in Santa Monica, California to extend the lease term from May 2016 to March 2020. Additionally, in March 2015 the Company leased approximately 7,000 additional square feet through March 2020. The cumulative base rent over the lease term is expected to be approximately $3.6 million . Legal Proceedings From time to time, the Company may become subject to legal proceedings, claims, and litigation arising in the ordinary course of business. The Company is not currently a party to any material legal proceedings, other than as described below. The Company filed a complaint against Sonic Automotive and Sonic Divisional Operations (collectively “Sonic”) on August 9, 2013 in the U.S. District Court for the Central District of California. The litigation concerns Sonic’s commercial use of the “True Price” mark. The Company was seeking an injunction prohibiting Sonic from using the “True Price” mark, as well as monetary damages incurred by the Company due to Sonic’s unlawful infringement. On July 29, 2015, the Company and Sonic reached an agreement in principle to settle the litigation and entered into a “Term Sheet” reflecting the material terms of settlement. On August 4, 2015, the Company entered into a settlement agreement with Sonic. Pursuant to the settlement agreement, Sonic will discontinue use of the “True Price” mark and has transferred all of its rights to that mark to the Company, and the lawsuit has been dismissed. On March 9, 2015, the Company was named as a defendant in a lawsuit filed in the U.S. District Court in the Southern District of New York (the "NY Lanham Act Litigation"). The complaint in the NY Lanham Act Litigation, purportedly filed on behalf of numerous automotive dealers who are not participating on the TrueCar platform, alleges that the Company has violated the Lanham Act as well as various state laws prohibiting unfair competition and deceptive acts or practices related to the Company’s advertising and promotional activities. The complaint seeks injunctive relief in addition to over $250 million in damages as a result of the alleged diversion of customers from the plaintiffs’ dealerships to TrueCar Certified Dealers. On April 7, 2015, the Company filed an answer to the complaint. Thereafter, the plaintiffs amended their complaint, and on July 13, 2015, the Company filed a motion to dismiss the amended complaint. The Company believes that the amended complaint is without merit, and it intends to vigorously defend itself in this matter. Based on the preliminary nature of the proceedings in this case, the outcome of this legal proceeding, including the anticipated legal defense costs, remains uncertain; accordingly, the Company cannot predict the ultimate outcome, or reasonably estimate the probability of or the range of loss, if any, for this action. As a result, no loss accrual has been recorded in the Company’s consolidated financial statements related to this matter. If this matter is not resolved in the Company’s favor, losses arising from the results of litigation or settlements, as well as ongoing defense costs, could have a material adverse effect on the Company’s business, financial condition, results of operations and cash flows. On May 20, 2015, the Company was named as a defendant in a lawsuit filed by the California New Car Dealers Association in the Superior Court for the County of Los Angeles (the "CNCDA Litigation"). The complaint in the CNCDA Litigation seeks declaratory and injunctive relief based on allegations that the Company is operating in the State of California as an unlicensed automobile dealer and autobroker. The complaint does not seek monetary relief. On July 20, 2015, the Company filed a "demurrer" to the complaint, which is a pleading that requests the court to dismiss the case. Thereafter, the plaintiffs amended their complaint, and on September 11, 2015, the Company filed a demurrer to the amended complaint. The Company believes that the amended complaint is without merit, and it intends to vigorously defend itself in this matter. Based on the preliminary nature of the proceedings in this case, the outcome of this legal proceeding, including the anticipated legal defense costs, remains uncertain; accordingly, the Company cannot predict the ultimate outcome or reasonably estimate the probability of or the range of loss, if any, for this action. As a result, no loss accrual has been recorded in the Company’s consolidated financial statements related to this matter. If this matter is not resolved in the Company’s favor, losses arising from the results of litigation or settlements, as well as ongoing defense costs, could have a material adverse effect on the Company’s business, financial condition, results of operations and cash flows. On May 27, 2015, a purported securities class action complaint was filed in the U.S. District Court for the Central District of California (the “Federal Securities Litigation”) by Satyabrata Mahapatra naming the Company and two other individuals not affiliated with the Company as defendants. On June 15, 2015, the plaintiff filed a Notice of Errata and Correction purporting to name Scott Painter and Michael Guthrie as individual defendants in lieu of the two individual defendants named in the complaint. On October 5, 2015, the plaintiffs amended their complaint. As amended, the complaint in the Federal Securities Litigation seeks an award of unspecified damages, interest and attorneys' fees based on allegations that the defendants made false and/or misleading statements, and failed to disclose material adverse facts about the Company’s business, operations, prospects and performance. Specifically, the amended complaint alleges that during the putative class period, the defendants made false and/or misleading statements and/or failed to disclose that: (i) the Company’s business practices violated unfair competition and deceptive trade practice laws (i.e., the issues raised in the NY Lanham Act Litigation); (ii) the Company acts as a dealer and broker in car sales transactions without proper licensing, in violation of various states’ laws that govern car sales (i.e., the issues raised in the CNCDA Litigation); and (iii) as a result of the above, the Company’s registration statements, prospectuses, quarterly and annual reports, financial statements, SEC filings, press releases, and other statements and documents were materially false and misleading at times relevant to the amended complaint and putative class period. The amended complaint asserts a putative class period stemming from May 16, 2014 to July 23, 2015. On October 19, 2015, the Company filed a motion to dismiss the amended complaint. The Company believes that the complaint is without merit and it intends to vigorously defend itself in this matter. Based on the preliminary nature of the proceedings in this case, the outcome of this legal proceeding, including the anticipated legal defense costs, remains uncertain; accordingly, the Company cannot predict the ultimate outcome or reasonably estimate the probability of or the range of loss, if any, for this action. As a result, no loss accrual has been recorded in the Company’s consolidated financial statements related to this matter. If this matter is not resolved in the Company’s favor, losses arising from the results of litigation or settlements, as well as ongoing defense costs, could have a material adverse effect on the Company’s business, financial condition, results of operations and cash flows. On July 30, 2015, the Company was named as a defendant in a lawsuit filed in the Superior Court for the County of Los Angeles by numerous automotive dealers who are participating on the TrueCar platform (the "Participating Dealer Litigation"). On September 9, 2015, the plaintiffs amended their complaint. Both as originally filed and as subsequently amended, the complaint in the Participating Dealer Litigation sought declaratory and injunctive relief based on allegations that the Company is engaging in unfairly competitive practices and is operating as an unlicensed automobile dealer and autobroker in contravention of various state laws. Neither the original nor amended complaint sought an award of money damages. On September 29, 2015, the plaintiffs voluntarily dismissed this lawsuit “without prejudice,” which means that the Participating Dealer Litigation is currently resolved, but that it could be re-filed at a later date. Because this case is currently resolved, no loss accrual has been recorded in the Company’s consolidated financial statements related to this matter. If the Participating Dealer Litigation is re-filed at a later date or if additional similar litigation is filed against the Company, and if such litigation is not resolved in the Company's favor, losses arising from the results of litigation or settlements, as well as related defense costs or adverse changes in our dealer network, could have a material adverse effect on the Company’s business, financial condition, results of operations and cash flows. On August 11, 2015, the Company, certain of its executives and directors, and the underwriters of the Company’s initial public offering and secondary offering were named as defendants in a putative class action lawsuit filed in California Superior Court under the federal securities laws (the “California State Court Securities Litigation”). The complaint filed by Ning Shen and William Fitzpatrick, alleged that the Company’s registration statements in connection with the offerings contained false or misleading statements of material facts, and failed to disclose material adverse facts about the Company’s business, operations, prospects, and performance. On September 2, 2015, following the Company’s removal of the action from California state court to the U.S. District Court for the Central District of California, the plaintiffs voluntarily dismissed this lawsuit “without prejudice,” which means that the California State Court Securities Litigation is currently resolved, but that it could be re-filed at a later date. Because this case is currently resolved, no loss accrual has been recorded in the Company’s consolidated financial statements related to this matter. If the California State Court Securities Litigation is re-filed at a later date, or if additional similar litigation, such as the Federal Securities Litigation, is filed against the Company, and if such litigation is not resolved in the Company's favor, losses arising from the results of litigation or settlements, as well as ongoing defense costs, could have a material adverse effect on the Company’s business, financial condition, results of operations and cash flows. Employment Contracts The Company has entered into employment contracts with certain executives of the Company. Employment under these contracts is at-will employment. However, under the provisions of the contracts, the Company would incur severance obligations up to twelve months of the executive’s annual base salary for certain events such as involuntary terminations. Indemnifications In the ordinary course of business, the Company may provide indemnities of varying scope and terms to customers, vendors, lessors, investors, directors, officers, employees and other parties with respect to certain matters, including, but not limited to, losses arising out of the Company’s breach of such agreements, services to be provided by the Company, or from intellectual property infringement claims made by third-parties. These indemnifications may survive termination of the underlying agreement and the maximum potential amount of future payments the Company could be required to make under these indemnification provisions may not be subject to maximum loss provisions. The maximum potential amount of future payments the Company could be required to make under these indemnification provisions is indeterminable. To date, there has not been a material claim paid by the Company, nor has the Company been sued in connection with these indemnification arrangements. At September 30, 2015 and December 31, 2014 , the Company has not accrued a liability for these guarantees, because the likelihood of incurring a payment obligation, if any, in connection with these guarantees is not probable or reasonably estimable.

For the three and nine months ended September 30, 2015 , the Company recorded a reduction in warrant expense of $0.4 million and $1.0 million , respectively, due to the remeasurement to fair value of the unvested shares and vested shares earned during the period, which was primarily related to the reduction in the Company’s stock price. The reduction in expense has been reflected as a reduction to sales and marketing expense on the accompanying consolidated statements of comprehensive loss. For the three and nine months ended September 30, 2014 , the Company recognized expense of $0.5 million and $0.9 million , respectively. At September 30, 2015 and December 31, 2014 , the shares earned under this warrant agreement totaled 133,333 shares and 33,333 shares, respectively.

Income Tax Disclosure [Abstract]
Income taxes	Income Taxes In determining quarterly provisions for income taxes, the Company uses the annual estimated effective tax rate applied to the actual year-to-date loss. The Company’s annual estimated effective tax rate differs from the statutory rate primarily as a result of state taxes, tax amortization of goodwill and changes in the Company’s valuation allowance. The Company recorded $0.2 million and $0.1 million income tax expense for the three months ended September 30, 2015 and 2014 , respectively. The Company recorded $0.4 million income tax expense for the nine months ended September 30, 2015 and 2014 . There were no material changes to the Company’s unrecognized tax benefits in the three and nine months ended September 30, 2015 , and the Company does not expect to have any significant changes to unrecognized tax benefits through the end of the fiscal year. Due to the presence of net operating loss carryforwards, all income tax years remain open for examination by the Internal Revenue Service (“IRS") and various state taxing authorities. During the second quarter of 2015, the Company settled an IRS tax examination for the 2011 and 2012 tax years. Given the Company’s net operating losses, the IRS tax examination adjustments did not result in a tax assessment. The Company believes its income tax accruals at September 30, 2015 are reasonable.

Subsequent Events	Subsequent Events In October 2015, the Compensation Committee of the Company's Board of Directors (the "Compensation Committee") granted 1,686,875 restricted stock units with a weighted-average grant date fair value of $5.20 which vest quarterly over an approximate period of four years. Additionally, the Compensation Committee granted stock options to purchase 462,573 shares of the Company’s common stock at a weighted-average exercise price of $6.32 per share.

In November 2015, the Company committed to a plan to consolidate its Santa Monica real estate from five office locations to three locations. As part of this program, the Company will increase its Santa Monica real estate footprint from 68,000 square feet to 76,000 square feet and create operational efficiencies by reducing its number of locations. The Company plans to exit three locations and move into one new location in the fourth quarter of 2015. In accordance with accounting for exit and disposal activities, the Company estimates that it will incur lease termination costs of approximately $1.7 million .

Summary of Significant Accounting Policies (Policies)	9 Months Ended
	Sep. 30, 2015
Accounting Policies [Abstract]
Basis of presentation	Basis of Presentation The Company’s unaudited condensed consolidated financial statements have been prepared in conformity with accounting principles generally accepted in the United States of America (“GAAP”) and applicable rules and regulations of the U.S. Securities and Exchange Commission (“SEC”) for quarterly reports on Form 10-Q and Article 10-1 of Regulation S-X. Accordingly, some information and footnote disclosures required by GAAP for complete financial statements have been condensed or omitted pursuant to such rules and regulations. In the opinion of the Company’s management, the accompanying unaudited condensed consolidated financial statements and notes have been prepared on the same basis as the audited consolidated financial statements for the year ended December 31, 2014 and include all adjustments (consisting of normal recurring adjustments) necessary for a fair statement of the interim periods presented. The condensed consolidated balance sheet at December 31, 2014 has been derived from the audited financial statements at that date, but does not include all of the disclosures required by GAAP. The accompanying condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and notes thereto contained in the Company’s Form 10-K filed with the SEC on March 12, 2015.
Use of estimates	Use of Estimates The preparation of consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the dates of the consolidated financial statements, and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Assets and liabilities which are subject to judgment and use of estimates include sales allowances and allowances for doubtful accounts, the fair value of assets and liabilities assumed in business combinations, fair value of the capitalized facility leases, the recoverability of goodwill and long-lived assets, valuation allowances with respect to deferred tax assets, useful lives associated with property and equipment and intangible assets, contingencies, and the valuation and assumptions underlying stock-based compensation and other equity instruments. On an ongoing basis, the Company evaluates its estimates compared to historical experience and trends, which form the basis for making judgments about the carrying value of assets and liabilities. In addition, the Company engaged valuation specialists to assist with management’s determination of the valuation of its capitalized facility leases, fair values of assets and liabilities assumed in business combinations, and in periods prior to the Company’s initial public offering, valuation of common stock.
Segments	Segments The Company has one operating segment. The Company’s Chief Operating Decision Makers (“CODM”), the Chief Executive Officer and the Chief Financial Officer, manage the Company’s operations based on consolidated financial information for purposes of evaluating financial performance and allocating resources. The CODM review financial information on a consolidated basis, accompanied by information about transaction revenue and forecasts, consulting and other revenue (Note 13). All of the Company’s principal operations, decision-making functions and assets are located in the United States.
Recent accounting pronouncements	Recent Accounting Pronouncements Under the Jumpstart Our Business Startups Act (“JOBS Act”), the Company meets the definition of an emerging growth company. The Company has irrevocably elected to opt out of the extended transition period for complying with new or revised accounting standards pursuant to Section 107(b) of the JOBS Act. In September 2015, the Financial Accounting Standards Board ("FASB") issued new guidance regarding business combinations to simplify measurement-period adjustments. Under this guidance, an acquirer must recognize adjustments to provisional amounts that are identified during the measurement period in the reporting period in which the adjustment amounts are determined. This guidance also requires acquirers to present separately on the face of the income statement, or disclose in the notes, the portion of the amount recorded in current period earnings by line item that would have been recorded in previous reporting periods. The new guidance is effective for annual and interim reporting periods beginning after December 15, 2015 and must be applied prospectively. The adoption of this guidance is not expected to have an impact on the Company’s consolidated financial statements. In April 2015, the FASB issued new guidance related to the presentation of debt issuance costs, which requires debt issuance costs to be presented in the balance sheet as a direct deduction for the associated debt liability. The new guidance is effective for annual and interim reporting periods beginning after December 15, 2015. Early adoption is permitted for financial statements that have not been previously issued. The adoption of this guidance is not expected to have an impact on the Company’s consolidated financial statements. In April 2015, the FASB issued new guidance related to the customer’s accounting for fees paid in a cloud computing arrangement, which provides guidance to customers about whether a cloud computing arrangement includes a software license. If a cloud computing arrangement includes a software license, then the customer should account for the software license element of the arrangement consistent with the acquisition of other software licenses. If a cloud computing arrangement does not include a software license, the customer should account for the arrangement as a service contract. The new guidance is effective for annual and interim reporting periods beginning after December 15, 2015. Early adoption is permitted. The adoption of this guidance is not expected to have an impact on the Company’s consolidated financial statements. In May 2014, the FASB issued guidance related to revenue from contracts with customers. Under this guidance, revenue is recognized when promised goods or services are transferred to customers in an amount that reflects the consideration that is expected to be received for those goods or services. The updated standard will replace all existing revenue recognition guidance under GAAP when it becomes effective and permits the use of either the retrospective or cumulative effect transition method. In August 2015, the FASB deferred the effective date to January 1, 2018, with early adoption beginning January 1, 2017. The Company is evaluating the impact of adopting this guidance on its consolidated financial statements.
