Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Summary of Significant Accounting Policies Basis of Presentation and Consolidation The consolidated financial statements include the accounts of InnerWorkings, Inc. and its subsidiaries. All significant intercompany accounts and transactions have been eliminated in consolidation. Reclassifications Certain prior year amounts have been reclassified to conform to the current presentation. These reclassifications have not been material and have not affected net income. 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 can 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 income (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. The net realized gains (losses) on foreign currency transactions was a gain of $0.6 million , a loss of $(3.3) million and a loss of $(0.8) million for the years ended December 31, 2016 , 2015 and 2014 , respectively. As further discussed in Note 2, the net realized losses on foreign currency transactions for the year ended December 31, 2015 , includes a charge of $1.5 million for the remeasurement of the Company's net assets in Venezuela. 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 it 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, revenues are 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. Cash and Cash Equivalents The Company considers all highly liquid investments purchased with a maturity of three months or less to be cash equivalents. Accounts Receivable Accounts receivable are uncollateralized customer obligations due under normal trade terms. Payment terms with customers are generally 30 to 90 days from the invoice date. Accounts receivable are stated at the amount billed to the customer, less an estimate for potential bad debts. Interest is not generally accrued on outstanding balances. The carrying amount of accounts receivable is reduced by an allowance that reflects management’s best estimate of the amounts that will not be collected. The Company estimates the collectability of its accounts receivable based on a combination of factors including, but not limited to, customer credit ratings and historical experience. In circumstances where the Company is aware of a specific customer’s inability to meet its financial obligations to the Company (e.g., bankruptcy filings or substantial downgrading of credit ratings), the Company provides allowances for bad debts against amounts due to reduce the net recognized receivable to the amount it reasonably believes will be collected. Aged receivables are reviewed on a regular basis and uncollectible accounts are written off when all reasonable collection efforts have been exhausted. Inventories Inventories are stated at the lower of cost or net realizable value. Cost is determined by the first-in, first-out method. Net realizable value is based upon an estimated average selling price reduced by estimated costs of disposal. Inventories primarily consist of purchased finished goods. Finished goods inventory includes consigned inventory held on behalf of customers as well as inventory held at third-party fulfillment centers and subcontractors. Property and Equipment Property and equipment are stated at cost, less accumulated depreciation. Depreciation is computed using the straight-line method over the estimated useful lives of the respective assets. The estimated useful lives, by asset class, are as follows: Computer equipment 3 years Software, including internal-use software 1 to 10 years Office equipment 5 years Furniture and fixtures 7 years Leasehold improvements are depreciated using the straight-line method over the shorter of their estimated useful lives or the terms of the related leases. Internal-Use Software In accordance with ASC 350-40, Intangibles—Goodwill and Other, Internal-Use Software, certain costs incurred in the planning and evaluation stage of internal-use computer software are expensed as incurred. Certain costs incurred during the application development stage are capitalized and included in property and equipment. Capitalized internal-use software costs are depreciated over the expected economic useful life of three to ten years using the straight-line method. Capitalized internal-use software asset depreciation expense for the years ended December 31, 2016 , 2015 and 2014 was $9.2 million , $8.6 million and $7.2 million , respectively and is included in total depreciation expense. At December 31, 2016 and 2015 , the net book value of internal-use software was $26.0 million and $25.8 million , respectively. Effective October 1, 2016, the Company changed the estimated useful lives of some of its software assets. The estimated useful lives of such assets were increased by an average of approximately 4.5 years , see note 7. Goodwill Goodwill represents the excess of purchase price and related costs over the value assigned to the net tangible and identifiable intangible assets of businesses acquired. 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 its fourth fiscal quarter of each year. Under ASC 350, an entity is permitted to first assess qualitative factors to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount as a basis for determining whether it is necessary to perform the quantitative goodwill impairment test. If the quantitative test is required, in the first step, the fair value for each reporting unit is compared to its book value including goodwill. In the case that the fair value is less than the book value, a second step is performed which compares the implied fair value of goodwill to the book value of goodwill. The fair value for the goodwill is determined based on the difference between the fair value of the reporting unit and the net fair values of the identifiable assets and liabilities. If the implied fair value of the goodwill is less than the book value of the goodwill, the difference is recognized as an impairment. At October 1, 2016 , the Company elected to perform a qualitative assessment of the likelihood that goodwill is impaired. Based on the assessment, no impairment was identified as of October 1, 2016 . The Company does not believe that goodwill is impaired as of December 31, 2016 . During the fourth quarter of 2015 , the Company recorded a non-cash, goodwill asset impairment charge of $37.5 million . For additional information related to the goodwill analysis, see Note 4. The fair value estimates used in the goodwill impairment analysis required significant judgment. The Company's fair value estimates for purposes of determining the goodwill impairment charge 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. Other Intangible Assets In accordance with ASC 350 , Intangibles—Goodwill and Other, the Company amortizes its intangible assets with finite lives over their respective estimated useful lives and reviews for impairment whenever impairment indicators exist. 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-competition 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-competition agreements, trade names and patents are being amortized on the straight-line basis over their estimated weighted-average useful lives of approximately four years , thirteen years and nine years , respectively. In the fourth quarter of 2016 , the Company recorded a non-cash, intangible asset impairment charge of $0.1 million . For additional information related to the intangible asset impairment, see Note 5. Shipping and Handling Costs Shipping and handling costs are classified in cost of goods sold in the consolidated statements of operations. Income Taxes The Company accounts for income taxes in accordance with ASC 740, Income Taxes , under which deferred tax assets and liabilities are recognized based upon anticipated future tax consequences attributable to differences between financial statement carrying values of assets and liabilities and their respective tax bases. A valuation allowance is established to reduce the carrying value of deferred tax assets if it is considered more likely than not that such assets will not be realized. Any change in the valuation allowance would be charged to income in the period such determination was made. The Company recognizes the tax benefit from an uncertain tax position only if it is “more likely than not” the tax position will be sustained on examination by the taxing authorities, based on the technical merits of the position. The tax benefits recognized in the financial statements from such positions are then measured based on the largest benefit that has a greater than 50% likelihood of being realized upon settlement. The Company’s policy is to recognize interest and penalties accrued on any unrecognized tax benefits as a component of income tax expense. There were no interest or penalties related to unrecognized tax benefits for the years ended December 31, 2016 , 2015 and 2014 . Based on the Company’s evaluation, it was concluded that there are no significant uncertain tax positions requiring recognition in its financial statements. The evaluation was performed for the tax years ended December 31, 2016 , 2015 , 2014 and 2013 , the tax years which remain subject to examination by major tax jurisdictions as of December 31, 2016 . Advertising Costs of advertising, which are expensed as incurred by the Company, were $1.4 million , $1.0 million and $0.5 million for the years ended December 31, 2016 , 2015 and 2014 , respectively and are included in selling, general and administrative expenses in the consolidated statement of operations. Comprehensive Loss The components of accumulated comprehensive loss included in the Consolidated Balance Sheets at December 31, 2016 and 2015 are as follows (in thousands): Foreign Currency Translation Adjustments Balance at December 31, 2014 $ (5,401 ) Other comprehensive loss before reclassifications (8,592 ) Net current-period other comprehensive loss (8,592 ) Balance at December 31, 2015 (13,993 ) Other comprehensive loss before reclassifications (6,806 ) Net current-period other comprehensive loss (6,806 ) Balance at December 31, 2016 $ (20,799 ) Stock-Based Compensation The Company accounts for stock-based compensation awards 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 for restricted shares. 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. Stock-based compensation, a non-cash expense, is recognized during the period is based on the portion of the share-based payment awards that are ultimately expected to vest. Accordingly, stock-based compensation cost recognized has been reduced for estimated forfeitures. Forfeitures are estimated at the time of grant and revised, if necessary, in subsequent periods if actual forfeitures differ from those estimates. Stock-based compensation expense is included in selling, general and administrative expenses in the consolidated statement of operations. Venezuelan Highly Inflationary Economy Since January 1, 2010, Venezuela has been designated as a highly inflationary economy under GAAP. In accordance with GAAP, local subsidiaries in highly inflationary economies are required to use the U.S. dollar as their functional currency and remeasure the monetary assets and liabilities not denominated in U.S. dollars using the rate applicable to conversion of a currency for purposes of dividend remittances. All exchange gains and losses resulting from remeasurement are recognized currently in income. Prior to December 31, 2015, the Company translated the net assets and transactions of its Venezuelan subsidiary using the official exchange rate of 6.3 bolivars for each U.S. Dollar. In February 2015, the Venezuelan government introduced a new currency exchange system referred to as the SIMADI which is intended to be a market-driven rate and is more widely available than the official rate or the auction-based exchange system known as the SICAD. Based on the Company’s facts and circumstances as of December 31, 2015, the SIMADI rate was determined to be the most appropriate rate for reporting the operations of the Company’s Venezuelan subsidiary. As of December 31, 2015, the SIMADI rate was approximately 198 bolivars for each U.S. Dollar. The remeasurement of the Company’s net assets from the official rate of 6.3 to the SIMADI rate resulted in a foreign exchange loss of approximately $1.5 million during the fourth quarter of 2015. This loss is included in other expense on the consolidated statement of operations. Recent Accounting Pronouncements In January 2017, the FASB issued Accounting Standards Update No. 2017-04, Simplifying the Test for Goodwill Impairment ("ASU 2017-04"), which simplifies 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. 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 effects of awards are required to be recognized in the income statement when the awards vest or are settled, as opposed to in additional paid-in capital under the current guidance. The standard also provides an option to recognize gross share-based compensation expense with actual forfeitures recognized as they occur, which the Company has elected to adopt. 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. Early adoption is permitted. In the first quarter of 2017, the Company will apply a modified retrospective transition method to account for the changes under the standard related to income taxes and the policy election for recording forfeitures as they occur. 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") 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). We currently anticipate adopting 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, we anticipate 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). We are currently evaluating the full impact that ASU No. 2014-09 will have on the Company’s consolidated financial statements. Historically, the Company generally reports revenue on a gross basis because the Company has been determined to be the primary obligor in its arrangements to procure marketing materials and other products for our customers. In March 2016, the FASB issued further guidance on principal versus agent considerations. We are currently evaluating the impact of the principal versus agent guidance on our classification of revenues and cost of goods sold. The new 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 expects to adopt the standard in the first quarter of 2018. In July 2015, the FASB issued Accounting Standards Update 2015-11, Inventory (Topic 330): Simplifying the Measurement of Inventory , ("ASU 2015-11"). ASU 2015-11 applies to inventory that is measured using first-in, first-out (FIFO) or average cost. Under the updated guidance, an entity should measure inventory that is within scope at the lower of cost and net realizable value, which is the estimated selling prices in the ordinary course of business, less reasonably predictable costs of completion, disposal and transportation. Subsequent measurement is unchanged for inventory that is measured using last-in, last-out (LIFO). The standard is effective for annual and interim periods beginning after December 15, 2016 and should be applied prospectively with early adoption permitted at the beginning of an interim or annual reporting period. The Company adopted ASU 2015-11in the fourth quarter of 2016, the adoption had no material impact on its consolidated financial statements and related disclosures. In August 2014, the FASB issued Accounting Standards Update 2014-15, Presentation of Financial Statements – Going Concern , ("ASU 2014-15"). ASU 2014-15 requires management to evaluate whether there are conditions and events that raise substantial doubt about the entity's ability to continue as a going concern and to provide disclosures in certain circumstances. The standard is effective for annual and interim periods beginning after December 15, 2016. The Company adopted ASU 2014-15 in the fourth quarter of 2016, the adoption had no material impact on its consolidated financial statements and related disclosures.

Acquisitions

Business Combinations [Abstract]
Acquisitions	Acquisitions Contingent Consideration In connection with certain of the Company’s acquisitions, contingent consideration is payable in cash or common stock 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 11, 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. The Company has recorded $19.3 million in contingent consideration at December 31, 2016 related to these arrangements. During the years ended December 31, 2016 , 2015 and 2014 , the Company recorded income (expense) of $(10.4) million , $0.3 million and $37.9 million due to changes in the fair value of the contingent consideration liability. For the year ended December 31, 2016 , the Company's fair value adjustment to the contingent consideration liability includes an adjustment of $ 10.7 million of expense to increase the liability relating to the EYELEVEL acquisition due to strong financial performance in recent periods and an improvement in forecasted results. This improved performance was primarily driven by significant expansion within EYELEVEL's existing customer base during 2016 . As a result of this growth and the increase in forecast, the probability of EYELEVEL achieving the target threshold for the final earn-out measurement period increased from less than probable to highly probable as of June 30, 2016 and further increased in probability as of December 31, 2016 . These probability changes were the primary drivers of the increases in the fair value of the contingent consideration liability in these periods. The large year-to-date increase in fair value resulting from these probability changes also takes in to account the acquisition agreement's earn-out payment structure for the final measurement period, which begins funding at $ 12.0 million based on cumulative EBITDA of $ 30.0 million but pays nothing below that threshold and up to a maximum payout of $ 24.0 million if cumulative EBITDA of $ 40.0 million is achieved. In addition to this increase to the contingent consideration liability for EYELEVEL there was also a decrease in the fair value of other earn-out agreements of $ 0.3 million for the year ended December 31, 2016 . As of December 31, 2016 , the potential maximum contingent consideration payments and their respective fair values are payable as follows (in thousands): Maximum Potential Payment Fair Value of Liability 2017 67,832 19,283 Total $ 67,832 $ 19,283 If the performance measures required by the purchase agreements are not achieved, the Company may pay less than the maximum amounts presented in the table above, depending on the terms of the agreement. While the maximum potential payments shown in the table are $67.8 million , the Company estimates the fair value of the payments that will be made is $19.3 million . Shares Issued as Consideration for Acquisitions Purchase agreements entered by the Company for business combinations often state that the purchase price, including contingent consideration, is to be paid in shares of the Company’s common stock. The value of the shares for each issuance is determined by the closing price of the Company’s common stock on dates specified in each separate agreement. Generally, the date that determines the share value is the date of the purchase agreement, the last date in a contingent consideration measurement period or the date of issuance to the sellers. The following table presents the number of shares issued as consideration for acquisitions and contingent consideration and the corresponding value of those shares during the years ended December 31, 2016 , 2015 and 2014 (in thousands, except per share amounts): Shares of Common Stock Issued Value of Shares Average Share Value Year ended December 31, 2016: Payments of contingent consideration 244 2,012 8.25 Year ended December 31, 2015: Payments of contingent consideration 238 1,570 6.59 Year ended December 31, 2014: Payments of contingent consideration 1,092 9,034 8.27

The Company believes that goodwill is not impaired as of December 31, 2016. 2015 Goodwill Impairment Charge In the fourth quarter of 2015, the Company performed its annual goodwill impairment test. In the first step of the impairment test, the Company concluded that the carrying amount of a reporting unit in the International segment exceeded its fair value, requiring the Company to perform the second step of the impairment test to measure the amount of impairment loss, if any. The fair value of the North America reporting unit exceeded its carrying value and the second step was not necessary. Based upon fair value estimates of long-lived assets and discounted cash flows of the reporting unit, the Company compared the implied fair value of the goodwill in this reporting unit with the carrying value. The test resulted in a $37.5 million non-cash, goodwill impairment charge which was recognized in the fourth quarter of 2015. No tax benefit was recognized on the goodwill impairment charge. This charge had no impact on the Company’s cash flows or compliance with debt covenants.

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-competition 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-competition 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 $5.5 million , $5.8 million and $7.4 million for the years ended December 31, 2016 , 2015 and 2014 , respectively. The estimated amortization expense for the next five years and thereafter, is as follows (in thousands): 2017 $ 4,982 2018 4,541 2019 4,247 2020 4,082 2021 3,780 Thereafter 9,906 $ 31,538 Customer List and Trade Name Impairment Charges During the fourth quarter of 2016 , the Company recorded a non-cash, intangible asset impairment charge of $0.1 million related to a trade name acquired in a prior year business combination in the International segment. During the fourth quarter of 2015 , the Company recognized a $0.2 million non-cash, intangible asset impairment charge related to certain customer lists acquired in prior year business combinations in the EMEA segment. Due to the global realignment discussed in Note 6, the Company evaluated the affected markets and identified certain customer lists for which undiscounted projected cash flows of the customers in those markets did not exceed the recorded book value of the customer lists. As such, the Company recorded an impairment charge of $0.2 million to reduce the customer lists to their respective fair values during its fourth quarter of 2015.

Restructuring and Related Activities [Abstract]
Restructuring Activities and Other Charges	Restructuring Activities and 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 deemed unnecessary. In connection with these actions, the Company incurred total 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 termination and other associated costs.

The Credit Agreement includes a revolving commitment amount of $175 million in the aggregate with a maturity date of September 25, 2019 and provides the Company the right to increase the aggregate commitment amount by an additional $50 million . Outstanding borrowings under the revolving credit facility are guaranteed by the Company’s material domestic subsidiaries. The Company’s obligations under the Credit Agreement and such domestic subsidiaries’ guaranty obligations are secured by substantially all of their respective assets. The ranges of applicable rates charged for interest on outstanding loans and letters of credit are 125-250 basis point spread for letter of credit fees and loans based on the Eurodollar rate and 25-150 basis point spread for loans based on the base rate. The terms of the Credit Agreement include various covenants, including covenants that require the Company to maintain a maximum leverage ratio and a minimum interest coverage ratio.

Secured Borrowing Arrangements Certain international subsidiaries are party to short-term secured borrowing arrangements which allow the Company to borrow against the value of a pool of current accounts receivable. The Company retains possession of the accounts receivable which are pledged as collateral. The pledged amounts are immaterial to the consolidated accounts receivable balance. Legal 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 as of December 31, 2016) in fees and damages, and this claim is currently pending. 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. All of the pending civil matters have been stayed in deference to the Company's related criminal complaint. 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 $0.6 million as of December 31, 2016). 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. In February 2014, shortly following the Company’s announcement of its intention to restate certain historical financial statements, an individual filed a putative securities class action complaint in the United States District Court for the Northern District of Illinois entitled Van Noppen v. InnerWorkings et al . The complaint, as amended in July 2014, alleges that the Company and certain executive officers violated federal securities laws by making materially false or misleading statements or omissions and by engaging in a scheme to defraud purchasers of securities, relating to the Company’s financial results and prospects. The purported misstatements and scheme relate to the Company’s inside sales initiative and the Productions Graphics business based in France. The complaint seeks unspecified damages, interest, attorneys’ fees and other costs. The Company and individual defendants dispute the claims. On September 29, 2014, the Company and individual defendants filed a motion to dismiss the complaint for failure to state a claim. On September 30, 2015, the Court granted in part and denied in part the motion to dismiss, resulting in the dismissal with prejudice of all claims relating to the inside sales initiative. On March 18, 2016, the parties reached an agreement in principle to settle the litigation. The settlement provides for payment to the class of $6.0 million , including plaintiff’s attorneys’ fees, in exchange for a full and final release and includes a denial of liability or any wrongdoing by the Company and the individual defendants. The settlement payment was fully paid by the Company’s insurance carrier. On November 2, 2016, the Court issued an order approving the settlement and dismissing the action with prejudice. On December 12, 2014, the Company received a derivative demand letter on behalf of Tom Turberg, a purported stockholder, demanding that the Company’s Board of Directors investigate and take action on behalf of the Company against the executive officers named in the Van Noppen action as well as certain past and current members of the Audit Committee of the Board of Directors. The demand letter’s allegations relate to (i) the Company’s restatement of financial statements for the fourth quarter of 2011 through the third quarter of 2013, (ii) the Company’s use of gross revenue accounting, (iii) incentive compensation paid to executive officers in 2011 and 2012, (iv) allegations in the Van Noppen action and (v) typographical errors in the 2013 Form 10-K. The Company's Board of Directors formed a Committee of independent directors to review the matters raised in the letter. The Committee, with assistance from the Committee's independent legal adviser, reviewed, investigated and evaluated the matters raised in the letter. Following the completion of its review, the Committee concluded that pursuit of the derivative claims was not in the best interests of the Company’s stockholders and recommended to the Board of Directors that it reject Turberg’s demand to pursue such claims. On November 2, 2016, the Board of Directors considered and accepted this recommendation. In March 2016, Capgemini America, Inc. (“Capgemini”) filed a complaint against the Company in the United States District Court for the Northern District of Illinois, alleging breach of contract and unjust enrichment in connection with the Company’s termination of Capgemini’s services under an agreement requiring Capgemini to provide certain business process outsourcing services to the Company. The complaint seeks damages of $2.4 million , interest, costs and attorney’s fees. The Company disputes the claims and intends to vigorously defend the matter. In April 2016, the Company filed an answer, affirmative defenses and counterclaims against Capgemini. The Company’s counterclaims allege fraud in the inducement, Illinois Consumer Fraud Act liability and breach of contract and seek compensatory and punitive damages, costs and attorney’s fees in an amount to be determined. In June 2016, the parties entered into a confidential settlement agreement in which the parties mutually released each other from all claims and the lawsuit was dismissed with prejudice.

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes The Company accounts for income taxes in accordance with ASC 740, Income Taxes ("ASC 740") , under which deferred tax assets and liabilities are recognized based upon anticipated future tax consequences attributable to differences between financial statement carrying values of assets and liabilities and their respective tax bases. The provision for income taxes consisted of the following components for the years ended December 31, 2016 , 2015 and 2014 (in thousands): Year Ended December 31, 2016 2015 2014 Current income tax expense: Federal $ 282 $ — $ 237 State 159 324 197 Foreign 6,430 5,021 4,070 Total current income tax expense 6,871 5,345 4,504 Deferred income tax expense (benefit): Federal 4,021 3,491 (278 ) State 418 465 (45 ) Foreign (355 ) 2,991 (2,326 ) Total deferred income tax expense (benefit) 4,084 6,947 (2,649 ) Income tax expense $ 10,955 $ 12,292 $ 1,855 The provision for income taxes for the years ended December 31, 2016 , 2015 and 2014 differs from the amount computed by applying the U.S. federal income tax rate of 35% to pretax income (loss) because of the effect of the following items (in thousands): Year Ended December 31, 2016 2015 2014 Tax expense (benefit) at U.S. federal income tax rate $ 5,364 $ (7,270 ) $ 15,957 State income taxes, net of federal income tax effect 449 500 1,410 Effect of non-US operations (501 ) (254 ) (1,621 ) Nontaxable contingent liability fair value changes and goodwill impairment 3,578 13,083 (14,334 ) Research and development credit (297 ) (422 ) (376 ) Change in valuation allowances 2,206 5,173 850 Prior year provision to return adjustment (137 ) 372 (172 ) Write-off of deferred taxes and tax receivables — 858 — Nondeductible expense and other 293 252 141 Income tax expense (benefit) $ 10,955 $ 12,292 $ 1,855 Deferred income taxes reflect the net tax effects of temporary differences between the carrying amounts of the Company's tax assets and liabilities for financial reporting purposes and the amounts used for income tax return reporting purposes. At December 31, 2016 and 2015 , the Company’s deferred tax assets and liabilities consisted of the following (in thousands): December 31, 2016 2015 Deferred tax assets: Inventory reserve $ 902 $ 838 Other reserves and allowances 4,233 5,365 Income tax basis in excess of financial statement basis in intangible assets 3,394 4,267 Deductible stock-based compensation 4,693 4,615 Net operating loss carryforward 9,496 8,667 Tax credit carryforwards 2,758 2,099 25,476 25,851 Valuation allowance (8,292 ) (6,500 ) Total deferred tax assets 17,184 19,351 Deferred tax liabilities: Prepaid & other expenses (139 ) (867 ) Fixed assets (5,913 ) (6,013 ) Intangible assets (21,392 ) (22,411 ) Total deferred tax liabilities (27,444 ) (29,291 ) Net deferred tax liability $ (10,260 ) $ (9,940 ) The realizability of deferred income tax assets is based on a more likely than not threshold. If it is determined that it is more likely than not that deferred income tax assets will not be realized, a valuation allowance must be established against the deferred income tax assets. Realization of deferred tax assets is dependent primarily on the generation of future taxable income. In considering the need for a valuation allowance the Company considers historical, as well as future projected, taxable income along with other positive and negative evidence in assessing the realizability of its deferred tax assets. For the years ended December 31, 2016 and 2015 , the Company recorded additional valuation allowances of $2.2 million and $5.2 million , respectively, related to operating losses for certain foreign locations. As of December 31, 2016 , the Company has gross federal and state net operating loss (“NOLs”) carryforwards of $3.5 million and $5.9 million , respectively. The federal carryovers begin to expire in 2023 and the state carryovers begin to expire in 2022 . The Internal Revenue Code imposes an annual limitation on the utilization of net operating loss carryforwards related to acquired corporations based on a statutory rate of return (usually the “applicable federal funds rate” as defined in the Internal Revenue Code) and the value of the corporation at the time of a “change in ownership” as defined by Section 382. The Company’s total federal NOL as of December 31, 2016 includes $0.4 million of NOLs from acquired corporations. These acquired NOLs have an annual limitation under Section 382 of the Internal Revenue Code of $0.1 million . As of December 31, 2016 , the Company had gross NOLs in France, Italy, Chile, Germany, South Africa and Switzerland of $21.2 million , $1.2 million , $3.0 million , $2.0 million , $1.4 million and $1.9 million , respectively, which have an indefinite carryover period. A reserve for an uncertain tax position was recorded during 2016 as a result of a sale of intellectual property during 2016 between the Company's subsidiaries for the following amount (in thousands): Uncertain tax positions Balance at December 31, 2015 $ — Additions based on tax positions related to the current year 280 Balance at December 31, 2016 $ 280 As of December 31, 2016 , the Company had gross federal and state research and development credit carryforwards of approximately $1.8 million and $0.5 million , respectively. The federal carryovers begin to expire in 2031 and the state carryovers begin to expire in 2016 . As a result of certain realization requirements of ASC 718, Stock-Based Compensation , the Company has not recorded certain deferred tax assets that arose directly from tax deductions related to equity compensation that are greater than the compensation recognized for financial reporting. As of December 31, 2016 , the Company has $3.1 million and $2.6 million in federal and state tax deductions, respectively, related to these stock option exercises which have not been recorded but are available to reduce taxable income in future periods. These deductions will be recorded to additional paid in capital in the period in which they are realized. The Company's intention is to indefinitely reinvest all undistributed earnings of its foreign subsidiaries in accordance with ASC 740. Deferred income taxes were not calculated on undistributed earnings (deficit) of foreign subsidiaries, which were $(3.0) million and $(10.7) million at December 31, 2016 and 2015 , respectively. Determination of the amount of unrecognized deferred tax liability on the undistributed earnings considered indefinitely reinvested is not practicable. The Company's income (loss) before taxes for its foreign operations was $13.6 million , $(29.6) million and $15.6 million for the years ended December 31, 2016 , 2015 and 2014 , respectively.

Fair Value Measurement

Fair Value Disclosures [Abstract]
Fair Value Measurement	Fair Value Measurement ASC 820, 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. The Company's potential contingent consideration payments relating to acquisitions occurring subsequent to January 1, 2009 are its only Level 3 liabilities as of December 31, 2016 and 2015 . The fair value of the liabilities determined by this analysis is primarily driven by the probability of reaching the performance measures required by the purchase agreements and the associated discount rate. Probabilities are 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 reaches the required performance measure, the estimated probability would be increased to 100% and if the measure is not reached, the probability would be reduced to reflect the amount earned, if any, depending on the terms of the agreement. Discount rates are determined by applying a risk premium to a risk-free interest rate. A one percentage point increase in the discount rate across all contingent consideration liabilities would result in a decrease to the fair value of approximately $0.1 million . The following tables set forth the Company’s financial assets and financial liabilities measured at fair value on a recurring basis and the basis of measurement at December 31, 2016 and 2015 , respectively (in thousands): 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) Assets: Money market funds (1) $ — $ — $ — $ — Liabilities: Contingent consideration $ 19,283 $ — $ — $ 19,283 At December 31, 2015 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) Assets: Money market funds (1) $ 667 $ 667 $ — $ — Liabilities: Contingent consideration $ 22,162 $ — $ — $ 22,162 (1) Included in cash and cash equivalents on the balance sheet. 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 at December 31, 2014 $ 32,582 Contingent consideration payments paid in cash (8,010 ) Contingent consideration payments paid in stock (1,570 ) Change in fair value (1) (270 ) Reclass to Due to seller — Foreign exchange impact (2) (570 ) Balance at December 31, 2015 22,162 Contingent consideration payments paid in cash (11,374 ) Contingent consideration payments paid in stock (2,012 ) Change in fair value (1) 10,417 Reclass to Due to seller 402 Foreign exchange impact (2) (312 ) Balance at December 31, 2016 $ 19,283 (1) Adjustments to original contingent consideration obligations recorded were the result of using revised financial forecasts and updated fair value measurements, see note 3. These changes are recognized within operating expenses on the consolidated statements of operations. (2) Changes in the contingent consideration liability which are caused by foreign exchange rate fluctuations are recognized in other comprehensive income.

Earnings Per Share [Abstract]
Earnings Per Share	Earnings (Loss) 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 ass uming 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. For the years ended December 31, 2016 , 2015 and 2014 , respectively, 3.8 million , 3.2 million and 2.4 million options and restricted common shares were excluded from the calculation as these options and restricted common shares were anti-dilutive. The computation of basic and diluted earnings per common share for the years ended December 31, 2016 , 2015 and 2014 , is as follows (in thousands, except per share amounts): Year Ended December 31, 2016 2015 2014 Numerator: Net income (loss) $ 4,370 $ (33,063 ) $ 43,736 Denominator: Denominator for basic earnings per share—weighted-average shares outstanding 53,607 52,791 52,096 Effect of dilutive securities: Employee stock options and restricted common shares 728 — 924 Contingently issuable shares 125 — 84 Denominator for diluted earnings per share 54,460 52,791 53,104 Basic earnings (loss) per share $ 0.08 $ (0.63 ) $ 0.84 Diluted earnings (loss) per share $ 0.08 $ (0.63 ) $ 0.82

Equity [Abstract]
Share Repurchase Program	Share Repurchase Program On February 12, 2015, the Company announced that its Board of Directors approved a share repurchase program authorizing the repurchase of up to an aggregate of $20 million of its common stock through open market and privately negotiated transactions over a two -year period. In November 2, 2016, the Board of Directors approved a two-year extension to the share repurchase program. The Company now expects the program to run through February 12, 2019. The timing and amount of any share repurchases will be determined based on market conditions, share price and other factors and the program may be discontinued or suspended at any time. Repurchases will be made in compliance with SEC rules and other legal requirements. During the year ended December 31, 2016, the Company did not repurchase any shares of its common stock. During the year ended December 31, 2015 , the Company repurchased 763,787 shares of its common stock for an aggregate amount of $4.9 million at an average cost of $6.41 per share. Shares repurchased under this program are recorded at acquisition cost, including related expenses.

Disclosure of Compensation Related Costs, Share-based Payments [Abstract]
Stock-Based Compensation Plans	Stock-Based Compensation Plans In 2006, the Company adopted the 2006 Stock Incentive Plan (the "Plan"). Upon adoption, all previously existing plans were merged into the Plan and ceased to separately exist. The Plan was amended and restated effective June 2016 resulting in an increase in the maximum number of shares of common stock that may be issued under the Plan by 2,900,000 , from 7,850,000 to 10,750,000 . The Company’s policy is to issue shares resulting from the exercise of stock options and conversion of restricted stock as new shares. The Company recorded share-based stock compensation expense of $5.6 million , $5.9 million and $5.4 million for the years ended December 31, 2016 , 2015 and 2014 , respectively. All stock-based compensation expense is recorded net of an estimated forfeiture rate and adjusted to reflect actual forfeiture activity. The estimated forfeiture rates applied as of December 31, 2016 ranged from 7.0% to 8.0% for various types of employees. The Company recorded $0.9 million , $1.0 million and $0.5 million of additional stock-based compensation expense for the years ended December 31, 2016 , 2015 and 2014 , respectively, for awards vested which exceeded the expense recorded using the estimated forfeiture rate. Stock Options Eligible employees receive non-qualified stock options as a portion of their total compensation. The options vest over various time periods depending upon the grant, but generally vest ratably over a four to five year service period. Vested options may be exercised and converted to one share of the Company’s common stock in exchange for the exercise price which is generally equal to the share price on the grant date. The Company measures the compensation cost based on the Black-Scholes option valuation model at the grant date. The stock-based compensation expense related to stock options for the years ended December 31, 2016 , 2015 and 2014 was $2.3 million , $2.4 million and $1.7 million , respectively. A summary of stock option activity for the years ended December 31, 2016 , 2015 and 2014 is as follows (in thousands, except per share amounts): Outstanding Options Weighted- Average Exercise Price Aggregate Intrinsic Value Outstanding at December 31, 2013 3,554 $ 8.52 $ 4,779 Granted 779 7.23 — Exercised (162 ) 4.82 3,302 Forfeited (125 ) 4.11 — Outstanding at December 31, 2014 4,046 8.35 4,725 Granted 975 6.87 — Exercised (405 ) 2.95 1,604 Forfeited (556 ) 9.58 — Outstanding at December 31, 2015 4,060 8.37 2,760 Granted 1,348 8.15 — Exercised (420 ) 6.27 4,455 Forfeited (227 ) 10.20 — Outstanding at December 31, 2016 4,761 $ 8.40 $ 8,655 Options vested and exercisable at December 31, 2016 2,458 $ 8.97 $ 4,514 The weighted-average fair values and ranges of exercise prices for stock options granted during the years ended December 31, 2016 , 2015 and 2014 , which vest ratably from one to five years , are as follows (in thousands, except per share amounts): Options Granted Weighted-Average Fair Value Exercise Prices 2014 779 $ 3.57 $7.18 - $8.72 2015 975 3.39 $6.21 - $8.20 2016 1,348 3.38 $6.99 - $9.20 The number of vested options totaled 2.5 million , 2.5 million and 2.7 million as of December 31, 2016 , 2015 and 2014 , respectively. The aggregate intrinsic value of options outstanding and exercisable represents the total pre-tax intrinsic value (the difference between the Company’s closing stock price on the last trading day of each fiscal year and the exercise price, multiplied by the number of in-the-money options) that would have been received by the option holders had all option holders exercised their options in 2016 , 2015 and 2014 , respectively. These amounts change based on the fair market value of the Company’s stock which was $9.85 , $7.50 and $7.79 on the last business day of the years ended December 31, 2016 , 2015 and 2014 , respectively. The following assumptions were utilized in the Black-Scholes valuation model for options granted in 2016 , 2015 and 2014 : 2016 2015 2014 Dividend yield — — — Risk-free interest rate 1.53%-2.03% 1.92%-2.12% 1.32%-2.17% Expected life 6.5 years 6 years 6 years Volatility 38.0%-50.0% 50 % 38.0%-50.0% No dividend yield is used as the Company does not currently, nor historically, pay dividends. The risk-free interest rate is based on actual U.S. Treasury zero-coupon rates for bonds commensurate with the expected term. Expected term is estimated based on historical experience related to similar awards, giving consideration to the contractual terms of the stock-based awards, vesting schedules and expectations of future employee behavior. The Company believes that its historical experience provides the best estimate of future expected life. The expected volatility assumption is based on the historical volatility of the Company’s common stock over a period commensurate with the expected term. There was $7.4 million , $5.6 million and $5.8 million of unrecognized compensation costs related to the stock options granted under the Plan as of December 31, 2016 , 2015 and 2014 , respectively. This cost is expected to be recognized over a weighted average period of 3.6 , 2.8 and 2.4 years, respectively. The following table summarizes information about all stock options outstanding for the Company as of December 31, 2016 (share amounts in thousands): Options Outstanding Options Vested Exercise Price Number Outstanding Weighted-Average Life Remaining (Years) Weighted- Average Exercise Price Number Exercisable Weighted- Average Exercise Price $2.36 - $4.36 64 2.29 $ 3.11 64 $ 3.11 $5.40 - $7.95 2,543 6.48 6.76 1,219 6.42 $8.17 - $11.97 1,395 7.79 8.89 462 9.65 $12.10 - $15.05 759 3.61 13.45 713 13.41 4,761 $ 8.40 2,458 $ 8.97 Restricted Common Shares Eligible employees receive restricted common shares as a portion of their total compensation. The restricted common shares vest over various time periods depending upon the grant, but generally vest from zero to five years and convert to common stock at the conclusion of the vesting period. The Company measures the compensation cost based on the closing market price of the Company’s common stock at the grant date. The stock-based compensation expense related to restricted common shares for the years ended December 31, 2016 , 2015 and 2014 was $3.3 million , $3.5 million and $3.6 million , respectively. A summary of restricted share activity is as follows (in thousands, except per share amounts): Outstanding Restricted Common Shares Weighted- Average Grant- Date Fair Value Nonvested Restricted Common shares at December 31, 2013 735 $ 10.45 Granted 736 7.59 Vested and transferred to unrestricted common stock (362 ) 8.90 Forfeited (19 ) 8.02 Nonvested Restricted Common shares at December 31, 2014 1,090 8.92 Granted 688 6.90 Vested and transferred to unrestricted common stock (465 ) 8.40 Forfeited (356 ) 8.19 Nonvested Restricted Common shares at December 31, 2015 957 7.66 Granted 559 8.24 Vested and transferred to unrestricted common stock (429 ) 7.71 Forfeited (78 ) 8.04 Nonvested Restricted Common shares at December 31, 2016 1,009 $ 7.92 There were $7.6 million , $6.9 million and $8.9 million of total unrecognized compensation costs related to the restricted common shares as of December 31, 2016 , 2015 and 2014 , respectively. This cost is expected to be recognized over a weighted average period of 2.6 , 2.7 and 2.4 years, as of December 31, 2016 , 2015 and 2014 , respectively.

Segment Reporting [Abstract]
Business Segments	Business Segments Segment information is prepared on the same basis that our CEO, who is our chief operating decision maker (“CODM”), manages the segments, evaluates financial results and makes key operating decisions. Effective in the first fiscal quarter of 2016, the Company implemented changes to the organizational structure of the Latin America and EMEA segments which included combining the two segments under single management and managing those businesses as one segment. In conjunction with this change, the CODM now manages the results of the Company 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. In fiscal year 2015, segments were organized and managed by the CODM as three business segments: North America, including the United States and Canada; EMEA, including operations in the United Kingdom, continental Europe, the Middle East, Africa and Asia; and LATAM, including operations in Mexico, South America and Central America. Prior period amounts have been restated to reflect this change. Management evaluates the performance of its operating segments based on net revenues and Adjusted EBITDA, which is a non-U.S. 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 2. 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 other items as described below. Management does not evaluate the performance of its operating segments using asset measures. The identifiable assets by segment disclosed in this note are those assets specifically identifiable within each segment and include cash, accounts receivable, inventory, goodwill and intangible assets. Shared service assets are primarily comprised of short-term investments, capitalized internal-use software and net property and equipment for the corporate headquarters. The table below presents financial information for our reportable operating segments and Other for the fiscal years noted (in thousands): North America International Other (2) Total Fiscal 2016: Net revenues from third parties $ 734,164 $ 356,540 $ — $ 1,090,704 Net revenues from other segments 6,029 17,526 (23,555 ) — Total net revenues 740,193 374,066 (23,555 ) 1,090,704 Adjusted EBITDA (1) 67,969 22,576 (31,392 ) 59,153 Fiscal 2015: Net revenues from third parties 708,532 320,821 — 1,029,353 Net revenues from other segments 7 8,691 (8,698 ) — Total net revenues 708,539 329,512 (8,698 ) 1,029,353 Adjusted EBITDA (1) 63,744 14,936 (27,881 ) 50,799 Fiscal 2014: Net revenues from third parties 688,942 311,191 — 1,000,133 Net revenues from other segments 48 5,589 (5,637 ) — Total net revenues 688,990 316,780 (5,637 ) 1,000,133 Adjusted EBITDA (1) 57,115 10,984 (26,445 ) 41,654 (1) Adjusted EBITDA, which represents income from operations with the addition of depreciation and amortization, stock-based compensation expense, income/expense related to changes in the fair value of contingent consideration liabilities, goodwill and intangible asset impairment charges, restructuring and other charges, secured assets reserves and legal fees from patent infringement defense, 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.

Summary of Significant Accoun28

Summary of Significant Accounting Policies (Policies)	12 Months Ended
	Dec. 31, 2016
Accounting Policies [Abstract]
Basis of Presentation and Consolidation	Basis of Presentation and Consolidation The consolidated financial statements include the accounts of InnerWorkings, Inc. and its subsidiaries. All significant intercompany accounts and transactions have been eliminated in consolidation.
Reclassifications	Reclassifications Certain prior year amounts have been reclassified to conform to the current presentation. These reclassifications have not been material and have not affected net income.
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 can 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 income (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 it 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, revenues are 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.
Cash and Cash Equivalents	Cash and Cash Equivalents The Company considers all highly liquid investments purchased with a maturity of three months or less to be cash equivalents.
Accounts Receivable	Accounts Receivable Accounts receivable are uncollateralized customer obligations due under normal trade terms. Payment terms with customers are generally 30 to 90 days from the invoice date. Accounts receivable are stated at the amount billed to the customer, less an estimate for potential bad debts. Interest is not generally accrued on outstanding balances. The carrying amount of accounts receivable is reduced by an allowance that reflects management’s best estimate of the amounts that will not be collected. The Company estimates the collectability of its accounts receivable based on a combination of factors including, but not limited to, customer credit ratings and historical experience. In circumstances where the Company is aware of a specific customer’s inability to meet its financial obligations to the Company (e.g., bankruptcy filings or substantial downgrading of credit ratings), the Company provides allowances for bad debts against amounts due to reduce the net recognized receivable to the amount it reasonably believes will be collected. Aged receivables are reviewed on a regular basis and uncollectible accounts are written off when all reasonable collection efforts have been exhausted.
Inventories	Inventories Inventories are stated at the lower of cost or net realizable value. Cost is determined by the first-in, first-out method. Net realizable value is based upon an estimated average selling price reduced by estimated costs of disposal. Inventories primarily consist of purchased finished goods. Finished goods inventory includes consigned inventory held on behalf of customers as well as inventory held at third-party fulfillment centers and subcontractors.
Property and Equipment	Property and Equipment Property and equipment are stated at cost, less accumulated depreciation. Depreciation is computed using the straight-line method over the estimated useful lives of the respective assets. The estimated useful lives, by asset class, are as follows: Computer equipment 3 years Software, including internal-use software 1 to 10 years Office equipment 5 years Furniture and fixtures 7 years Leasehold improvements are depreciated using the straight-line method over the shorter of their estimated useful lives or the terms of the related leases.
Internal-Use Software	Internal-Use Software In accordance with ASC 350-40, Intangibles—Goodwill and Other, Internal-Use Software, certain costs incurred in the planning and evaluation stage of internal-use computer software are expensed as incurred. Certain costs incurred during the application development stage are capitalized and included in property and equipment. Capitalized internal-use software costs are depreciated over the expected economic useful life of three to ten years using the straight-line method.
Goodwill	Goodwill Goodwill represents the excess of purchase price and related costs over the value assigned to the net tangible and identifiable intangible assets of businesses acquired. 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 its fourth fiscal quarter of each year. Under ASC 350, an entity is permitted to first assess qualitative factors to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount as a basis for determining whether it is necessary to perform the quantitative goodwill impairment test. If the quantitative test is required, in the first step, the fair value for each reporting unit is compared to its book value including goodwill. In the case that the fair value is less than the book value, a second step is performed which compares the implied fair value of goodwill to the book value of goodwill. The fair value for the goodwill is determined based on the difference between the fair value of the reporting unit and the net fair values of the identifiable assets and liabilities. If the implied fair value of the goodwill is less than the book value of the goodwill, the difference is recognized as an impairment. At October 1, 2016 , the Company elected to perform a qualitative assessment of the likelihood that goodwill is impaired. Based on the assessment, no impairment was identified as of October 1, 2016 . The Company does not believe that goodwill is impaired as of December 31, 2016 . During the fourth quarter of 2015 , the Company recorded a non-cash, goodwill asset impairment charge of $37.5 million . For additional information related to the goodwill analysis, see Note 4. The fair value estimates used in the goodwill impairment analysis required significant judgment. The Company's fair value estimates for purposes of determining the goodwill impairment charge 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.
Other Intangible Assets	Other Intangible Assets In accordance with ASC 350 , Intangibles—Goodwill and Other, the Company amortizes its intangible assets with finite lives over their respective estimated useful lives and reviews for impairment whenever impairment indicators exist. 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-competition 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-competition agreements, trade names and patents are being amortized on the straight-line basis over their estimated weighted-average useful lives of approximately four years , thirteen years and nine years , respectively.
Shipping and Handling Costs	Shipping and Handling Costs Shipping and handling costs are classified in cost of goods sold in the consolidated statements of operations.
Income Taxes	Income Taxes The Company accounts for income taxes in accordance with ASC 740, Income Taxes , under which deferred tax assets and liabilities are recognized based upon anticipated future tax consequences attributable to differences between financial statement carrying values of assets and liabilities and their respective tax bases. A valuation allowance is established to reduce the carrying value of deferred tax assets if it is considered more likely than not that such assets will not be realized. Any change in the valuation allowance would be charged to income in the period such determination was made. The Company recognizes the tax benefit from an uncertain tax position only if it is “more likely than not” the tax position will be sustained on examination by the taxing authorities, based on the technical merits of the position. The tax benefits recognized in the financial statements from such positions are then measured based on the largest benefit that has a greater than 50% likelihood of being realized upon settlement.
Advertising	Advertising Costs of advertising, which are expensed as incurred by the Company, were $1.4 million , $1.0 million and $0.5 million for the years ended December 31, 2016 , 2015 and 2014 , respectively and are included in selling, general and administrative expenses in the consolidated statement of operations.
Comprehensive Income	Comprehensive Loss The components of accumulated comprehensive loss included in the Consolidated Balance Sheets at December 31, 2016 and 2015 are as follows (in thousands): Foreign Currency Translation Adjustments Balance at December 31, 2014 $ (5,401 ) Other comprehensive loss before reclassifications (8,592 ) Net current-period other comprehensive loss (8,592 ) Balance at December 31, 2015 (13,993 ) Other comprehensive loss before reclassifications (6,806 ) Net current-period other comprehensive loss (6,806 ) Balance at December 31, 2016 $ (20,799 )
Share-Based Compensation	Stock-Based Compensation The Company accounts for stock-based compensation awards 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 for restricted shares. 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. Stock-based compensation, a non-cash expense, is recognized during the period is based on the portion of the share-based payment awards that are ultimately expected to vest. Accordingly, stock-based compensation cost recognized has been reduced for estimated forfeitures. Forfeitures are estimated at the time of grant and revised, if necessary, in subsequent periods if actual forfeitures differ from those estimates. Stock-based compensation expense is included in selling, general and administrative expenses in the consolidated statement of operations.
Recent Accounting Pronouncements	Recent Accounting Pronouncements In January 2017, the FASB issued Accounting Standards Update No. 2017-04, Simplifying the Test for Goodwill Impairment ("ASU 2017-04"), which simplifies 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. 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 effects of awards are required to be recognized in the income statement when the awards vest or are settled, as opposed to in additional paid-in capital under the current guidance. The standard also provides an option to recognize gross share-based compensation expense with actual forfeitures recognized as they occur, which the Company has elected to adopt. 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. Early adoption is permitted. In the first quarter of 2017, the Company will apply a modified retrospective transition method to account for the changes under the standard related to income taxes and the policy election for recording forfeitures as they occur. 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") 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). We currently anticipate adopting 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, we anticipate 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). We are currently evaluating the full impact that ASU No. 2014-09 will have on the Company’s consolidated financial statements. Historically, the Company generally reports revenue on a gross basis because the Company has been determined to be the primary obligor in its arrangements to procure marketing materials and other products for our customers. In March 2016, the FASB issued further guidance on principal versus agent considerations. We are currently evaluating the impact of the principal versus agent guidance on our classification of revenues and cost of goods sold. The new 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 expects to adopt the standard in the first quarter of 2018. In July 2015, the FASB issued Accounting Standards Update 2015-11, Inventory (Topic 330): Simplifying the Measurement of Inventory , ("ASU 2015-11"). ASU 2015-11 applies to inventory that is measured using first-in, first-out (FIFO) or average cost. Under the updated guidance, an entity should measure inventory that is within scope at the lower of cost and net realizable value, which is the estimated selling prices in the ordinary course of business, less reasonably predictable costs of completion, disposal and transportation. Subsequent measurement is unchanged for inventory that is measured using last-in, last-out (LIFO). The standard is effective for annual and interim periods beginning after December 15, 2016 and should be applied prospectively with early adoption permitted at the beginning of an interim or annual reporting period. The Company adopted ASU 2015-11in the fourth quarter of 2016, the adoption had no material impact on its consolidated financial statements and related disclosures. In August 2014, the FASB issued Accounting Standards Update 2014-15, Presentation of Financial Statements – Going Concern , ("ASU 2014-15"). ASU 2014-15 requires management to evaluate whether there are conditions and events that raise substantial doubt about the entity's ability to continue as a going concern and to provide disclosures in certain circumstances. The standard is effective for annual and interim periods beginning after December 15, 2016. The Company adopted ASU 2014-15 in the fourth quarter of 2016, the adoption had no material impact on its consolidated financial statements and related disclosures.
