Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Summary of Significant Accounting Policies Basis of Presentation of Interim Financial Statements The accompanying unaudited condensed consolidated financial statements of InnerWorkings, Inc. and subsidiaries (the “Company”) included herein have been prepared to conform to the rules and regulations of the Securities and Exchange Commission (“SEC”) and accounting principles generally accepted in the United States (“GAAP”) for interim financial information. Certain information and footnote disclosures normally included in financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to such rules and regulations. In the opinion of management, all adjustments considered necessary for a fair presentation of the accompanying unaudited financial statements have been included, and all adjustments are of a normal and recurring nature. The operating results for the three and nine months ended September 30, 2017 are not necessarily indicative of the results to be expected for the full year ending December 31, 2017 . These condensed interim consolidated financial statements and notes should be read in conjunction with the Company’s Consolidated Financial Statements and Notes thereto as of and for the year ended December 31, 2016 included in the Company’s Annual Report on Form 10-K filed with the SEC on March 9, 2017. Description of the Business The Company was incorporated in the state of Delaware on January 3, 2006. The Company is a leading global marketing execution firm for some of the world's most marketing intensive companies, including those in the Fortune 1000, across a wide range of industries. As a comprehensive outsourced enterprise solution, the Company leverages proprietary technology, an extensive supplier network and deep domain expertise to streamline the creation, production and distribution of marketing and promotional materials, signage and displays, retail experiences, events and promotions and packaging across every major market worldwide. The items the Company sources are generally procured through the marketing supply chain and are referred to collectively as marketing materials. The Company’s technology and database of information is designed to capitalize on excess manufacturing capacity and other inefficiencies in the traditional marketing and print supply chain to obtain favorable pricing and to deliver high-quality products and services. The Company is organized and managed as two business segments, North America and International, and is viewed as two operating segments by the chief operating decision maker for purposes of resource allocation and assessing performance. See Note 14 for further information about the Company’s reportable segments. Preparation of Financial Statements and Use of Estimates The preparation of the consolidated financial statements is in conformity with accounting principles generally accepted in the United States ("GAAP"). GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities as of the date of the financial statements and the reported amounts of revenue and expenses during the reporting periods. On an ongoing basis, the Company evaluates its estimates, including those related to product returns, allowance for doubtful accounts, inventories and inventory valuation, valuation and impairments of goodwill and long-lived assets, income taxes, accrued bonus, contingencies, stock-based compensation and litigation costs. The Company bases its estimates on historical experience and on other assumptions that its management believes are reasonable under the circumstances. These estimates form the basis for making judgments about the carrying value of assets and liabilities when those values are not readily apparent from other sources. Actual results may differ from those estimates. Foreign Currency Translation The Company determines the functional currency for its parent company and each of its subsidiaries by reviewing the currencies in which their respective operating activities occur. Assets and liabilities of these operations are translated into U.S. currency at the rates of exchange at the balance sheet date. Income and expense items are translated at average monthly rates of exchange. The resulting translation adjustments are included in accumulated other comprehensive loss, a separate component of stockholders’ equity. Transaction gains and losses arising from activities in other than the applicable functional currency are calculated using average exchange rates for the applicable period and reported in net income as a non-operating item in each period. Non-monetary balance sheet items denominated in a currency other than the applicable functional currency are translated using the historical rate. Revenue Recognition The Company recognizes revenue upon meeting all of the following revenue recognition criteria, which is typically met upon shipment or delivery of our products to customers: (i) persuasive evidence of an arrangement exists through customer contracts and orders, (ii) the customer takes title and assumes the risks and rewards of ownership, (iii) the sales price charged is fixed or determinable as evidenced by customer contracts and orders and (iv) collectability is reasonably assured. Unbilled revenue represents shipments that have been made to customers for which the related account receivable has not yet been invoiced. In accordance with Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) 605-45, Revenue Recognition – Principal Agent Considerations , the Company generally reports revenue on a gross basis because the Company is the primary obligor in its arrangements to procure marketing materials and other products for its customers. Under these arrangements, the Company is responsible for the fulfillment, including the acceptability, of the printed materials and other products. In addition, the Company: (i) determines which suppliers are included in its network, (ii) has discretion to select from among the suppliers within its network, (iii) is obligated to pay its suppliers regardless of whether the Company is paid by its customers and (iv) has reasonable latitude to establish exchange price. In some transactions, the Company also has general inventory risk and is involved in the determination of the nature or characteristics of the printed materials and products. When the Company is not the primary obligor, revenue is reported on a net basis. The Company recognizes revenue for creative, design, installation, warehousing and other services provided to its customers which may be delivered in conjunction with the procurement of marketing materials at the time when delivery and customer acceptance occur and all other revenue recognition criteria are met. When provided on a stand-alone basis, the Company recognizes revenue for these services upon completion of the service. Service revenue has not been material to the Company’s overall revenue to date. The Company records taxes collected from customers and remitted to governmental authorities on a net basis. Stock-Based Compensation The Company accounts for stock-based compensation awards to employees and directors in accordance with ASC 718, Compensation – Stock Compensation . Compensation expense is measured by determining the fair value of each award using the Black-Scholes option valuation model for stock options or the closing share price on the grant date for restricted shares and performance share units. The fair value is then recognized over the requisite service period of the awards, which is generally the vesting period, on a straight-line basis for the entire award. On June 1, 2017, the Compensation Committee approved, pursuant to the 2006 Stock Incentive Plan, awards of performance share units (“PSUs”) for certain executive officers and employees. The PSUs are performance-based awards that will settle in shares of the Company's common stock, in an amount between 0% and 200% of the target award level, based on the cumulative adjusted earnings per share and the return on invested capital achieved by the Company between April 1, 2017 and December 31, 2019. Compensation expense for PSUs is measured by determining the fair value of the award using the closing share price on the grant date and is recognized ratably from the grant date to the vesting date for the number of awards expected to vest. The amount of compensation expense recognized for PSUs is dependent upon a quarterly assessment of the likelihood of achieving the performance conditions. Stock-based compensation cost recognized during the period is based on the full grant date fair value of the share-based payment awards adjusted for any forfeitures during the period. The Company recorded $2.4 million and $1.7 million in stock-based compensation expense for the three months ended September 30, 2017 and 2016 , respectively, and $5.3 million and $4.1 million for the nine months ended September 30, 2017 and 2016 , respectively. Recent Accounting Pronouncements In May 2017, the FASB issued Accounting Standards Update No. 2017-09, Scope of Modification Accounting ("ASU 2017-09"), which amends ASC 718, Compensation - Stock Compensation. This ASU amends the scope of modification accounting for share-based payment arrangements, provides guidance on the types of changes to the terms or conditions of share-based payment awards to which an entity would be required to apply modification accounting. The new guidance will allow companies to make certain changes to awards without accounting for them as modifications. It does not change the accounting for modifications. The new guidance will be applied prospectively to awards modified on or after the adoption date. This new guidance is effective for interim and annual reporting periods beginning after December 15, 2017 with early adoption permitted. The Company is currently evaluating the impact of adopting this standard on its consolidated financial statements. In January 2017, the FASB issued Accounting Standards Update No. 2017-04, Simplifying the Test for Goodwill Impairment ("ASU 2017-04"), which simplified the accounting for goodwill impairment by removing Step 2 of the goodwill impairment test. This ASU is effective for annual or interim goodwill impairment tests in fiscal years beginning after December 15, 2019 and should be applied on a prospective basis. Early adoption is permitted for interim or annual goodwill impairment tests performed on testing dates after January 1, 2017. The adoption of this standard is not expected to have a material impact on the consolidated financial statements and related disclosures. In August 2016, the FASB issued Accounting Standards Update No. 2016-15, Classification of Certain Cash Receipts and Cash Payments ("ASU 2016-15"), which amends ASC 230, Statement of Cash Flows . This ASU provides guidance on the statement of cash flows presentation of certain transactions where diversity in practice exists. The guidance is effective for interim and annual periods beginning after December 15, 2017 and early adoption is permitted. The Company is currently in the process of evaluating the impact of adoption of this ASU on the Company's consolidated financial statements. In March 2016, the FASB issued Accounting Standards Update No. 2016-09, Compensation - Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting , ("ASU 2016-09") which simplifies several aspects of the accounting for share-based payment transactions, including the income tax consequences, classification of awards as either equity or liabilities and classification on the statement of cash flows. Under the standard, the income tax effect of awards is required to be recognized in the income statement when the awards vest or are settled, as opposed to in additional paid-in capital under Topic 718. The standard also provides an option to recognize gross share-based compensation expense with actual forfeitures recognized as they occur. ASU 2016-09 is effective for annual and interim periods beginning after December 15, 2016. This guidance can be applied either prospectively, retrospectively or using a modified retrospective transition method. The Company adopted all amendments to the standard at January 1, 2017. The amendments related to the classification of excess tax benefits on the statement of cash flows were adopted prospectively and the classification of employee taxes paid on the statement of cash flows when an employer withholds shares for tax-withholding purposes was adopted retrospectively. The adoption of both resulted in no prior period adjustments. With the adoption of the standards related to eliminating the requirement that excess tax benefits be realized before companies can recognize them and election to recognize forfeitures as they occur, the Company elected to use the modified retrospective method which resulted in changes to retained earnings, components of equity and net assets. The net cumulative effect of these changes resulted in a $2.1 million increase to additional paid in capital, a $1.5 million decrease to deferred tax liabilities and a $0.6 million decrease to retained earnings. In February 2016, the FASB issued Accounting Standards Update No. 2016-02, Leases (Topic 842) , ("ASU 2016-02") which increases transparency and comparability among organizations by recognizing lease assets and lease liabilities on the balance sheet and requires disclosure of key information about leasing arrangements. ASU 2016-02 requires lessees to recognize a right-of-use asset and a lease liability for most leases in the balance sheet as well as other qualitative and quantitative disclosures. The update is to be applied using a modified retrospective method and is effective for annual periods beginning after December 15, 2018 and interim periods within those annual periods. The Company is currently evaluating the impact of adopting this standard on its consolidated financial statements. In May 2014, the FASB issued Accounting Standards Update 2014-09, Revenue from Contracts with Customers (Topic 606) (“ASU 2014-09"), which outlines a single comprehensive model for entities to use in accounting for revenue using a five-step process that supersedes virtually all existing revenue guidance. ASU 2014-09 is based on principles that govern the recognition of revenue at an amount an entity expects to be entitled when products are transferred to customers. The FASB has issued several amendments to the standard since ASU 2014-09. The guidance permits two methods of adoption: retrospectively to each prior reporting period presented (full retrospective method) or retrospectively with the cumulative effect of initially applying the guidance recognized at the date of initial application (the modified retrospective transition method). The Company will adopt the standard electing to use the modified retrospective transition method. The standard provides an option to apply the transition method to all contracts at the inception date or only to contracts that are not completed as of that date. At the current time, the Company only intends to apply the standard to contracts that are not completed as of December 31, 2017. Also, the Company anticipates disclosing the aggregate effect of contract modifications that occur before the beginning of the earliest reporting period presented (only for contracts not completed at the date of adoption). The Company continues to review the impact of the standard on all revenue transactions as well as assessing and implementing any potential changes to systems, processes and internal controls required to meet the standard’s reporting and disclosure requirements. While the review is not fully complete, the Company has identified certain areas of the standard that the Company is evaluating further such as principle versus agent considerations and the timing of revenue recognition. The Company does not currently expect significant changes in financial statement presentation and expects revenue will typically continue to be recognized at a point in time rather than over time. Those conclusions are subject to change as the review is completed in the fourth quarter of 2017. Under the current guidance, the Company defers revenue for inventory billed but not yet shipped. Under the standard, in certain situations the Company may be able to recognize revenue for inventory billed but not yet shipped, which could accelerate the timing, but not the total amount, of revenue recognized and would not impact the timing of cash flows. The Company cannot reasonably estimate quantitative information related to the impact of the standard on our financial statements at this time. The standard will be effective for annual reporting periods beginning after December 15, 2017. Earlier application is permitted only as of annual reporting periods beginning after December 15, 2016, including interim reporting periods within that reporting period. The Company will adopt the standard in the first quarter of 2018.

Contingent Consideration

Contingent Consideration	Sep. 30, 2017
Business Combinations [Abstract]
Contingent Consideration	Contingent Consideration In connection with certain of the Company’s acquisitions, contingent consideration is payable in cash or common stock of the Company upon the achievement of certain performance measures over future periods. The Company recorded the acquisition date fair value of the contingent consideration liability as additional purchase price. As discussed in Note 10, the process for determining the fair value of the contingent consideration liability consists of reviewing financial forecasts and assessing the likelihood of reaching the required performance measures based on factors specific to each acquisition as well as the Company’s historical experience with similar arrangements. Subsequent to the acquisition date, the Company estimates the fair value of the contingent consideration liability each reporting period and any adjustments made to the fair value are recorded in the Company’s results of operations. If an acquisition reaches the required performance measures within the reporting period, the fair value of the contingent consideration liability is increased to 100% , the maximum potential payment, and reclassified to due to seller. On June 30, 2017, the EYELEVEL acquisition reached the required performance measures at the end of its earnout period and the balance of the fair value of the contingent consideration liability was reclassified to due to seller. During the third quarter of 2017 , the Company paid $17.7 million to settle the final balance owed to the sellers. As of September 30, 2017, no contingent consideration or due to seller balances remain on the Company's balance sheet and all liabilities have been settled. During the three months ended September 30, 2017 and 2016 , the Company recorded (income) expense of $(0.2) million and $0.8 million , respectively. During the nine months ended September 30, 2017 and 2016 , the Company recorded expense of $0.7 million and $10.0 million , respectively. Please refer to Note 10 for a further summary of activities related to the contingent consideration balance for the nine months ended September 30, 2017 .

In accordance with ASC 350, Intangibles – Goodwill and Other ("ASC 350"), goodwill is not amortized, but instead is tested for impairment annually, or more frequently if circumstances indicate a possible impairment may exist. Absent any interim indicators of impairment, the Company tests for goodwill impairment as of the first day of the fourth fiscal quarter of each year. The fair value estimates used in the goodwill impairment analysis require significant judgment. The Company's fair value estimates for purposes of performing the analysis are considered Level 3 fair value measurements. The fair value estimates were based on assumptions that management believes to be reasonable, but that are inherently uncertain, including estimates of future revenues and operating margins and assumptions about the overall economic climate and the competitive environment for the business. The Company assesses for goodwill impairment each reporting period and does not believe that goodwill is impaired as of September 30, 2017 .

Impairment indicators could include significant under-performance relative to the historical or projected future operating results, significant changes in the manner of use of assets, significant negative industry or economic trends or significant changes in the Company’s market capitalization relative to net book value. Any changes in key assumptions used by the Company, including those set forth above, could result in an impairment charge and such a charge could have a material adverse effect on the Company’s consolidated results of operations. The Company’s intangible assets consist of customer lists, non-compete agreements, trade names and patents. The Company’s customer lists, which have an estimated weighted-average useful life of approximately fourteen years, are being amortized using the economic life method. The Company’s non-compete agreements, trade names and patents are being amortized on a straight-line basis over their estimated weighted-average useful lives of approximately four years, thirteen years and nine years, respectively. Amortization expense related to these intangible assets was $1.2 million and $1.4 million for the three months ended September 30, 2017 and 2016 , respectively, and $3.7 million and $4.2 million for the nine months ended September 30, 2017 and 2016 , respectively.

Restructuring and Related Activities [Abstract]
Restructuring Activities and Other Charges	Restructuring Activities and Other Charges On December 14, 2015, the Company approved a global realignment plan that allowed the Company to more efficiently meet client needs across its international platform. Through improved integration of global resources, the plan created back office and other efficiencies and allowed for the elimination of approximately 100 positions. In connection with these actions, the Company incurred pre-tax cash restructuring charges of $6.7 million , the majority of which were recognized during 2016. These cash charges included approximately $5.6 million for employee severance and related benefits and $1.1 million for lease and contract terminations and other associated costs. The charges were all incurred by the end of 2016 with payouts of the charges occurring in 2017. As required by law, the Company consulted with each of the affected countries’ local Works Councils throughout the plan. For the three and nine months ended September 30, 2017 , the Company recognized no additional restructuring charges related to this plan, as the plan was completed by the end of 2016. The following table summarizes the accrued restructuring activities for this plan for the nine months ended September 30, 2017 (in thousands): Employee Severance and Related Benefits Lease and Contract Termination Costs Other Total Balance at December 31, 2016 $ 1,349 $ 17 $ 200 $ 1,566 Cash payments (397 ) (17 ) (200 ) (614 ) Balance at September 30, 2017 $ 952 $ — $ — $ 952 As of September 30, 2016, the Company recognized $5.5 million in restructuring charges related to this plan, of which $ 0.3 million , $4.2 million and $1.0 million related to the North America, International and Other segments, respectively.

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes The Company's tax provision for interim periods is determined using an estimate of its annual effective tax rate, adjusted for discrete items. The Company’s reported effective income tax rate was 34.5% and 42.7% for the three months ended September 30, 2017 and 2016 , respectively, and 35.7% and 109.2% for the nine months ended September 30, 2017 and 2016 . The Company’s effective income tax rate differs from the U.S. federal statutory rate each year due to certain operations that are subject to tax incentives, state and local taxes, and foreign taxes that are different than the U.S. federal statutory rate. In addition, the effective tax rate can be impacted each period by discrete factors and events. The effective tax rates were affected by the fair value changes to contingent consideration in each period. Portions of the total amount recognized from fair value changes to contingent consideration relate to non-taxable acquisitions for which deferred taxes are not recognized, consistent with the treatment of goodwill and intangible assets for those acquisitions under U.S. GAAP. In the three months ended September 30, 2017 and 2016 , $0.2 million of income and $0.8 million of expense, respectively, was recognized from fair value changes to contingent consideration. In the nine months ended September 30, 2017 and 2016 , expense of $0.7 million and $10.0 million , respectively, was recognized from fair value changes to contingent consideration. The effective tax rate for the three and nine months ended September 30, 2017 was favorably impacted by $0.1 million and unfavorably impacted by $0.1 million , respectively, of stock-based compensation activity due to the adoption ASU 2016-09 on January 1, 2017. Valuation allowances are recorded to reduce deferred tax assets when it is more likely than not that a tax benefit will expire unutilized. At the end of each reporting period, the Company reviews the realizability of its deferred tax assets. During the second quarter of 2017, the valuation allowance balance was decreased for a Peruvian valuation allowance adjustment. The Company believed sufficient positive evidence existed to release the valuation allowance, therefore, the Company adjusted the valuation allowance by $0.8 million , resulting in a $0.2 million benefit to income tax expense for the nine months ended September 30, 2017 . Additionally, the Company continues to incur losses in jurisdictions which have valuation allowances against tax loss carryforwards, so a tax benefit has not been recognized in the financial statements for these losses.

Earnings Per Share	Sep. 30, 2017
Earnings Per Share [Abstract]
Earnings Per Share	Earnings Per Share Basic earnings (loss) per common share is calculated by dividing net income (loss) by the weighted average number of common shares outstanding for the period. Diluted earnings (loss) per share is calculated by dividing net income (loss) by the weighted average shares outstanding assuming dilution. Dilutive common shares outstanding is computed using the Treasury Stock Method and reflects the additional shares that would be outstanding if dilutive stock options were exercised and restricted stock and restricted stock units were settled for common shares during the period. In addition, dilutive shares would include any shares issuable related to PSUs for which the performance conditions have been met as of the end of the period. During the three months ended September 30, 2017 and 2016 , an aggregate of 1.3 million and 2.5 million options and restricted common shares, respectively, and during the nine months ended September 30, 2017 and 2016 , an aggregate of 2.4 million and 4.0 million options and restricted common shares, respectively, were excluded from the calculation as these options and restricted common shares were anti-dilutive. The computations of basic and diluted earnings (loss) per common share for three and nine months ended September 30, 2017 and 2016 are as follows (in thousands, except per share amounts): Three Months Ended September 30, Nine Months Ended September 30, 2017 2016 2017 2016 Numerator: Net income (loss) $ 7,528 $ 4,341 $ 17,479 $ (676 ) Denominator: Weighted-average shares outstanding – basic 53,964 53,818 53,962 53,536 Effect of dilutive securities: Employee and director stock options and restricted common shares 1,225 817 1,165 — Contingently issuable shares — 137 — — Weighted-average shares outstanding – diluted 55,189 54,772 55,127 53,536 Basic earnings (loss) per share $ 0.14 $ 0.08 $ 0.32 $ (0.01 ) Diluted earnings (loss) per share $ 0.14 $ 0.08 $ 0.32 $ (0.01 )

Fair Value Measurement	Sep. 30, 2017
Fair Value Disclosures [Abstract]
Fair Value Measurement	Fair Value Measurement ASC 820 includes a fair value hierarchy that is intended to increase consistency and comparability in fair value measurements and related disclosures. The fair value hierarchy is based on observable or unobservable inputs to valuation techniques that are used to measure fair value. Observable inputs reflect assumptions market participants would use in pricing an asset or liability based on market data obtained from independent sources while unobservable inputs reflect a reporting entity’s pricing based upon its own market assumptions. The fair value hierarchy consists of the following three levels: • Level 1: Inputs are quoted prices in active markets for identical assets or liabilities. • Level 2: Inputs are quoted prices for similar assets or liabilities in an active market, quoted prices for identical or similar assets or liabilities in markets that are not active, and inputs other than quoted prices that are observable and market-corroborated inputs, which are derived principally from or corroborated by observable market data. • Level 3: Inputs that are derived from valuation techniques in which one or more significant inputs or value drivers are unobservable. As of September 30, 2017 the Company no longer has any Level 3 assets or liabilities remaining on its condensed consolidated financial statements as a result of the finalization of the contingent consideration liabilities discussed in Note 2. As of December 31, 2016, the only Level 3 liabilities on the Company's financial statements related to its potential contingent consideration payments from acquisitions occurring subsequent to January 1, 2009. The fair value of the liabilities determined by this analysis was primarily driven by the probability of reaching the performance measures required by the applicable purchase agreements and the associated discount rates. Probabilities were estimated by reviewing financial forecasts and assessing the likelihood of reaching the required performance measures based on factors specific to each acquisition as well as the Company’s historical experience with similar arrangements. If an acquisition reached the required performance measure, the estimated probability would be increased to 100% and reclassified to due to seller, and if the measure was not reached, the probability would have been reduced to reflect the amount earned, if any, depending on the terms of the agreement. Discount rates were determined by applying a risk premium to a risk-free interest rate. The following table sets forth the Company’s financial assets and financial liabilities measured at fair value on a recurring basis and the basis of measurement at September 30, 2017 and December 31, 2016 (in thousands): At September 30, 2017 Total Fair Value Measurement Quoted Prices in Active Markets for Identical Assets (Level 1) Significant Other Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3) Liabilities: Contingent consideration $ — $ — $ — $ — At December 31, 2016 Total Fair Value Measurement Quoted Prices in Active Markets for Identical Assets (Level 1) Significant Other Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3) Liabilities: Contingent consideration $ 19,283 $ — $ — $ 19,283 The following table provides a reconciliation of the beginning and ending balances for the liabilities measured at fair value using significant unobservable inputs (Level 3) (in thousands): Fair Value Measurements at Reporting Date Using Significant Unobservable Inputs (Level 3) Contingent Consideration Balance as of December 31, 2016 $ (19,283 ) Change in fair value (1) (677 ) Contingent Consideration paid in cash 15,345 Contingent Consideration paid in stock 4,678 Foreign exchange impact (2) (63 ) Balance as of September 30, 2017 $ — (1) Adjustments to original contingent consideration obligations recorded were the result of using revised financial forecasts and actuals and updated fair value measurements.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies In October 2013, the Company removed the former owner of Productions Graphics from his role as President of Productions Graphics, the Company’s French subsidiary. He had been in that role since the Company’s 2011 acquisition of Productions Graphics, a European business then principally owned by him. In December 2013, the former owner of Productions Graphics initiated a wrongful termination claim in the Commercial Court of Paris seeking approximately €0.7 million (approximately $0.7 million ) in fees and damages. In anticipation of this claim, in November 2013, he also obtained a judicial asset attachment order in the amount of €0.7 million (approximately $1.0 million ) as payment security; the attachment order was confirmed in January 2014, and the Company filed an appeal of the order. In March 2015, the appellate court ruled in the Company’s favor in the attachment proceedings, releasing all attachments. The Company disputes the allegations of the former owner of Productions Graphics and intends to vigorously defend these matters. In February 2014, based on a review the Company initiated into certain transactions associated with the former owner of Productions Graphics, the Company concluded that he had engaged in fraud by inflating the results of the Productions Graphics business in order to induce the Company to pay him €7.1 million in contingent consideration pursuant to the acquisition agreement. In light of those findings, in February 2014, the Company filed a criminal complaint in France seeking to redress the harm caused by his conduct and this proceeding is currently pending. In addition, in September 2015, the Company initiated a civil claim in the Paris Commercial Court against the former owner of Productions Graphics, seeking civil damages to redress these same harms. In addition to these pending matters, there may be other potential disputes between the Company and the former owner of Productions Graphics relating to the acquisition agreement. The Company had paid €5.8 million (approximately $8.0 million ) in fixed consideration and €7.1 million (approximately $9.4 million ) in contingent consideration to the former owner of Productions Graphics; the remaining maximum contingent consideration under the acquisition agreemen t was €34.5 million (approximately $37.6 million ) and the Company has determined that none of this amount was earned and payable. In January 2014, a former finance employee of Productions Graphics initiated wrongful termination and overtime claims in the Labor Court of Boulogne-Billancourt, and he currently seeks damages of approximately €0.6 million (approximately $0.7 million ). The Company disputes these allegations and intends to vigorously defend these matters. In addition, the Company’s criminal complaint in France, described above, seeks to redress harm caused by this former employee in light of his participation in the fraudulent transactions described above. The labor claim has been stayed in deference to the Company’s related criminal complaint.

Segment Reporting [Abstract]
Business Segments	Business Segments Segment information is prepared on the same basis that our Chief Executive Officer, who is our chief operating decision maker (“CODM”), manages the segments, evaluates financial results, and makes key operating decisions. The Company is organized and managed as two business segments: North America and International. The North America segment includes operations in the United States and Canada; the International segment includes all other operations across Europe, Asia, Mexico, Central America and South America; Other consists of intersegment eliminations, shared service activities and unallocated corporate expenses. All transactions between segments are presented at their gross amounts and eliminated through Other. Management evaluates the performance of its operating segments based on revenues and Adjusted EBITDA, which is a non-GAAP financial measure. The accounting policies of each of the operating segments are the same as those described in the summary of significant accounting policies in Note 1. Adjusted EBITDA represents income from operations excluding depreciation and amortization, stock-based compensation expense, income/expense related to changes in the fair value of contingent consideration liabilities and restructuring and other charges. Management does not evaluate the performance of its operating segments using asset measures. The table below presents financial information for the Company’s reportable segments and Other for the three and nine month periods noted (in thousands): North America International Other Total Three Months Ended September 30, 2017: Revenue from third parties $ 196,966 $ 91,420 $ — $ 288,386 Revenue from other segments 1,294 4,761 (6,055 ) — Total revenue 198,260 96,181 (6,055 ) 288,386 Adjusted EBITDA (1) 20,827 6,865 (8,917 ) 18,775 Three Months Ended September 30, 2016: Revenue from third parties $ 185,199 $ 94,794 $ — $ 279,993 Revenue from other segments 3,401 9,065 (12,466 ) — Total revenue 188,600 103,859 (12,466 ) 279,993 Adjusted EBITDA (1) 16,411 7,444 (6,935 ) 16,920 North America International Other Total Nine Months Ended September 30, 2017 Revenue from third parties $ 569,440 $ 265,866 $ — $ 835,306 Revenue from other segments 4,136 11,108 (15,244 ) — Total revenue 573,576 276,974 (15,244 ) 835,306 Adjusted EBITDA (1) 57,827 16,314 (26,453 ) 47,688 Nine Months Ended September 30, 2016 Revenue from third parties $ 550,561 $ 269,725 $ — $ 820,286 Revenue from other segments 5,048 16,573 (21,621 ) — Total revenue 555,609 286,298 (21,621 ) 820,286 Adjusted EBITDA (1) 48,209 17,482 (22,284 ) 43,407 (1) Adjusted EBITDA, which represents income from operations with the addition of depreciation and amortization, stock-based compensation expense, change in the fair value of contingent consideration liabilities, restructuring, business development realignment costs, and professional fees related to ASC 606 implementation, is considered a non-GAAP financial measure under SEC regulations. Income from operations is the most directly comparable financial measure calculated in accordance with GAAP. The Company presents this measure as supplemental information to help investors better understand trends in its business results over time. The Company’s management team uses Adjusted EBITDA to evaluate the performance of the business. Adjusted EBITDA is not equivalent to any measure of performance required to be reported under GAAP, nor should this data be considered an indicator of the Company’s overall financial performance and liquidity. Moreover, the Adjusted EBITDA definition the Company uses may not be comparable to similarly titled measures reported by other companies.

In the opinion of management, all adjustments considered necessary for a fair presentation of the accompanying unaudited financial statements have been included, and all adjustments are of a normal and recurring nature. The operating results for the three and nine months ended September 30, 2017 are not necessarily indicative of the results to be expected for the full year ending December 31, 2017 .

Description of the Business	Description of the Business The Company was incorporated in the state of Delaware on January 3, 2006. The Company is a leading global marketing execution firm for some of the world's most marketing intensive companies, including those in the Fortune 1000, across a wide range of industries. As a comprehensive outsourced enterprise solution, the Company leverages proprietary technology, an extensive supplier network and deep domain expertise to streamline the creation, production and distribution of marketing and promotional materials, signage and displays, retail experiences, events and promotions and packaging across every major market worldwide. The items the Company sources are generally procured through the marketing supply chain and are referred to collectively as marketing materials. The Company’s technology and database of information is designed to capitalize on excess manufacturing capacity and other inefficiencies in the traditional marketing and print supply chain to obtain favorable pricing and to deliver high-quality products and services. The Company is organized and managed as two business segments, North America and International, and is viewed as two operating segments by the chief operating decision maker for purposes of resource allocation and assessing performance. See Note 14 for further information about the Company’s reportable segments.
Preparation of Financial Statements and Use of Estimates	Preparation of Financial Statements and Use of Estimates The preparation of the consolidated financial statements is in conformity with accounting principles generally accepted in the United States ("GAAP"). GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities as of the date of the financial statements and the reported amounts of revenue and expenses during the reporting periods. On an ongoing basis, the Company evaluates its estimates, including those related to product returns, allowance for doubtful accounts, inventories and inventory valuation, valuation and impairments of goodwill and long-lived assets, income taxes, accrued bonus, contingencies, stock-based compensation and litigation costs. The Company bases its estimates on historical experience and on other assumptions that its management believes are reasonable under the circumstances. These estimates form the basis for making judgments about the carrying value of assets and liabilities when those values are not readily apparent from other sources. Actual results may differ from those estimates.
Foreign Currency Translation	Foreign Currency Translation The Company determines the functional currency for its parent company and each of its subsidiaries by reviewing the currencies in which their respective operating activities occur. Assets and liabilities of these operations are translated into U.S. currency at the rates of exchange at the balance sheet date. Income and expense items are translated at average monthly rates of exchange. The resulting translation adjustments are included in accumulated other comprehensive loss, a separate component of stockholders’ equity. Transaction gains and losses arising from activities in other than the applicable functional currency are calculated using average exchange rates for the applicable period and reported in net income as a non-operating item in each period. Non-monetary balance sheet items denominated in a currency other than the applicable functional currency are translated using the historical rate.
Revenue Recognition	Revenue Recognition The Company recognizes revenue upon meeting all of the following revenue recognition criteria, which is typically met upon shipment or delivery of our products to customers: (i) persuasive evidence of an arrangement exists through customer contracts and orders, (ii) the customer takes title and assumes the risks and rewards of ownership, (iii) the sales price charged is fixed or determinable as evidenced by customer contracts and orders and (iv) collectability is reasonably assured. Unbilled revenue represents shipments that have been made to customers for which the related account receivable has not yet been invoiced. In accordance with Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) 605-45, Revenue Recognition – Principal Agent Considerations , the Company generally reports revenue on a gross basis because the Company is the primary obligor in its arrangements to procure marketing materials and other products for its customers. Under these arrangements, the Company is responsible for the fulfillment, including the acceptability, of the printed materials and other products. In addition, the Company: (i) determines which suppliers are included in its network, (ii) has discretion to select from among the suppliers within its network, (iii) is obligated to pay its suppliers regardless of whether the Company is paid by its customers and (iv) has reasonable latitude to establish exchange price. In some transactions, the Company also has general inventory risk and is involved in the determination of the nature or characteristics of the printed materials and products. When the Company is not the primary obligor, revenue is reported on a net basis. The Company recognizes revenue for creative, design, installation, warehousing and other services provided to its customers which may be delivered in conjunction with the procurement of marketing materials at the time when delivery and customer acceptance occur and all other revenue recognition criteria are met. When provided on a stand-alone basis, the Company recognizes revenue for these services upon completion of the service. Service revenue has not been material to the Company’s overall revenue to date. The Company records taxes collected from customers and remitted to governmental authorities on a net basis.
Stock-Based Compensation	Stock-Based Compensation The Company accounts for stock-based compensation awards to employees and directors in accordance with ASC 718, Compensation – Stock Compensation . Compensation expense is measured by determining the fair value of each award using the Black-Scholes option valuation model for stock options or the closing share price on the grant date for restricted shares and performance share units. The fair value is then recognized over the requisite service period of the awards, which is generally the vesting period, on a straight-line basis for the entire award. On June 1, 2017, the Compensation Committee approved, pursuant to the 2006 Stock Incentive Plan, awards of performance share units (“PSUs”) for certain executive officers and employees. The PSUs are performance-based awards that will settle in shares of the Company's common stock, in an amount between 0% and 200% of the target award level, based on the cumulative adjusted earnings per share and the return on invested capital achieved by the Company between April 1, 2017 and December 31, 2019. Compensation expense for PSUs is measured by determining the fair value of the award using the closing share price on the grant date and is recognized ratably from the grant date to the vesting date for the number of awards expected to vest. The amount of compensation expense recognized for PSUs is dependent upon a quarterly assessment of the likelihood of achieving the performance conditions. Stock-based compensation cost recognized during the period is based on the full grant date fair value of the share-based payment awards adjusted for any forfeitures during the period. The Company recorded $2.4 million and $1.7 million in stock-based compensation expense for the three months ended September 30, 2017 and 2016 , respectively, and $5.3 million and $4.1 million for the nine months ended September 30, 2017 and 2016 , respectively.
Recent Accounting Pronouncements	Recent Accounting Pronouncements In May 2017, the FASB issued Accounting Standards Update No. 2017-09, Scope of Modification Accounting ("ASU 2017-09"), which amends ASC 718, Compensation - Stock Compensation. This ASU amends the scope of modification accounting for share-based payment arrangements, provides guidance on the types of changes to the terms or conditions of share-based payment awards to which an entity would be required to apply modification accounting. The new guidance will allow companies to make certain changes to awards without accounting for them as modifications. It does not change the accounting for modifications. The new guidance will be applied prospectively to awards modified on or after the adoption date. This new guidance is effective for interim and annual reporting periods beginning after December 15, 2017 with early adoption permitted. The Company is currently evaluating the impact of adopting this standard on its consolidated financial statements. In January 2017, the FASB issued Accounting Standards Update No. 2017-04, Simplifying the Test for Goodwill Impairment ("ASU 2017-04"), which simplified the accounting for goodwill impairment by removing Step 2 of the goodwill impairment test. This ASU is effective for annual or interim goodwill impairment tests in fiscal years beginning after December 15, 2019 and should be applied on a prospective basis. Early adoption is permitted for interim or annual goodwill impairment tests performed on testing dates after January 1, 2017. The adoption of this standard is not expected to have a material impact on the consolidated financial statements and related disclosures. In August 2016, the FASB issued Accounting Standards Update No. 2016-15, Classification of Certain Cash Receipts and Cash Payments ("ASU 2016-15"), which amends ASC 230, Statement of Cash Flows . This ASU provides guidance on the statement of cash flows presentation of certain transactions where diversity in practice exists. The guidance is effective for interim and annual periods beginning after December 15, 2017 and early adoption is permitted. The Company is currently in the process of evaluating the impact of adoption of this ASU on the Company's consolidated financial statements. In March 2016, the FASB issued Accounting Standards Update No. 2016-09, Compensation - Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting , ("ASU 2016-09") which simplifies several aspects of the accounting for share-based payment transactions, including the income tax consequences, classification of awards as either equity or liabilities and classification on the statement of cash flows. Under the standard, the income tax effect of awards is required to be recognized in the income statement when the awards vest or are settled, as opposed to in additional paid-in capital under Topic 718. The standard also provides an option to recognize gross share-based compensation expense with actual forfeitures recognized as they occur. ASU 2016-09 is effective for annual and interim periods beginning after December 15, 2016. This guidance can be applied either prospectively, retrospectively or using a modified retrospective transition method. The Company adopted all amendments to the standard at January 1, 2017. The amendments related to the classification of excess tax benefits on the statement of cash flows were adopted prospectively and the classification of employee taxes paid on the statement of cash flows when an employer withholds shares for tax-withholding purposes was adopted retrospectively. The adoption of both resulted in no prior period adjustments. With the adoption of the standards related to eliminating the requirement that excess tax benefits be realized before companies can recognize them and election to recognize forfeitures as they occur, the Company elected to use the modified retrospective method which resulted in changes to retained earnings, components of equity and net assets. The net cumulative effect of these changes resulted in a $2.1 million increase to additional paid in capital, a $1.5 million decrease to deferred tax liabilities and a $0.6 million decrease to retained earnings. In February 2016, the FASB issued Accounting Standards Update No. 2016-02, Leases (Topic 842) , ("ASU 2016-02") which increases transparency and comparability among organizations by recognizing lease assets and lease liabilities on the balance sheet and requires disclosure of key information about leasing arrangements. ASU 2016-02 requires lessees to recognize a right-of-use asset and a lease liability for most leases in the balance sheet as well as other qualitative and quantitative disclosures. The update is to be applied using a modified retrospective method and is effective for annual periods beginning after December 15, 2018 and interim periods within those annual periods. The Company is currently evaluating the impact of adopting this standard on its consolidated financial statements. In May 2014, the FASB issued Accounting Standards Update 2014-09, Revenue from Contracts with Customers (Topic 606) (“ASU 2014-09"), which outlines a single comprehensive model for entities to use in accounting for revenue using a five-step process that supersedes virtually all existing revenue guidance. ASU 2014-09 is based on principles that govern the recognition of revenue at an amount an entity expects to be entitled when products are transferred to customers. The FASB has issued several amendments to the standard since ASU 2014-09. The guidance permits two methods of adoption: retrospectively to each prior reporting period presented (full retrospective method) or retrospectively with the cumulative effect of initially applying the guidance recognized at the date of initial application (the modified retrospective transition method). The Company will adopt the standard electing to use the modified retrospective transition method. The standard provides an option to apply the transition method to all contracts at the inception date or only to contracts that are not completed as of that date. At the current time, the Company only intends to apply the standard to contracts that are not completed as of December 31, 2017. Also, the Company anticipates disclosing the aggregate effect of contract modifications that occur before the beginning of the earliest reporting period presented (only for contracts not completed at the date of adoption). The Company continues to review the impact of the standard on all revenue transactions as well as assessing and implementing any potential changes to systems, processes and internal controls required to meet the standard’s reporting and disclosure requirements. While the review is not fully complete, the Company has identified certain areas of the standard that the Company is evaluating further such as principle versus agent considerations and the timing of revenue recognition. The Company does not currently expect significant changes in financial statement presentation and expects revenue will typically continue to be recognized at a point in time rather than over time. Those conclusions are subject to change as the review is completed in the fourth quarter of 2017. Under the current guidance, the Company defers revenue for inventory billed but not yet shipped. Under the standard, in certain situations the Company may be able to recognize revenue for inventory billed but not yet shipped, which could accelerate the timing, but not the total amount, of revenue recognized and would not impact the timing of cash flows. The Company cannot reasonably estimate quantitative information related to the impact of the standard on our financial statements at this time. The standard will be effective for annual reporting periods beginning after December 15, 2017. Earlier application is permitted only as of annual reporting periods beginning after December 15, 2016, including interim reporting periods within that reporting period. The Company will adopt the standard in the first quarter of 2018.

Income from operations is the most directly comparable financial measure calculated in accordance with GAAP. The Company presents this measure as supplemental information to help investors better understand trends in its business results over time. The Company’s management team uses Adjusted EBITDA to evaluate the performance of the business. Adjusted EBITDA is not equivalent to any measure of performance required to be reported under GAAP, nor should this data be considered an indicator of the Company’s overall financial performance and liquidity. Moreover, the Adjusted EBITDA definition the Company uses may not be comparable to similarly titled measures reported by other companies.
