Accounting Policies [Abstract]
Basis of Accounting, Policy [Policy Text Block]	Basis of Presentation-The condensed consolidated financial statements for the interim periods included herein are unaudited; however, they contain all adjustments (consisting of only normal recurring adjustments) which, in the opinion of management, are necessary to present fairly the consolidated financial position of the Company as of March 31, 2013, and the results of its operations and comprehensive income, cash flows and stockholders’ equity for the three months ended March 31, 2013 and 2012. The results of operations for the interim periods are not necessarily indicative of results that may be expected for any other interim period or for the full year. These condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and notes thereto for the year ended December 31, 2012, included in the Company's Annual Report on Form 10-K. Unless otherwise noted, the accounting policies used in preparing these condensed consolidated financial statements are the same as those described in the December 31, 2012 consolidated financial statements.
Consolidation, Policy [Policy Text Block]	Principles of Consolidation-The condensed consolidated financial statements include the accounts of Innodata Inc. and its wholly-owned subsidiaries and the Synodex and docGenix limited liability companies that are majority-owned by the Company. The non-controlling interests in the Synodex and docGenix limited liability companies are accounted for in accordance with Financial Accounting Standards Board (FASB) non-controlling interest guidance. All significant intercompany transactions and balances have been eliminated in consolidation.
Use of Estimates, Policy [Policy Text Block]	Use of Estimates-In preparing financial statements in conformity with accounting principles generally accepted in the United States of America, management is required to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Significant estimates include those related to revenue recognition, allowance for doubtful accounts and billing adjustments, long-lived assets, goodwill, valuation of deferred tax assets, valuation of securities underlying stock-based compensation, litigation accruals, pension benefits, valuation of derivative instruments and estimated accruals for various tax exposures.
New Accounting Pronouncements, Policy [Policy Text Block]	Recent Accounting Pronouncements- In the first quarter of 2013, the Company adopted changes issued by the FASB to the reporting of amounts reclassified out of accumulated other comprehensive income. These changes require an entity to report the effect of significant reclassifications out of accumulated other comprehensive income on the respective line items in net income if the amount being reclassified is required to be reclassified in its entirety to net income. For other amounts that are not required to be reclassified in their entirety to net income in the same reporting period, an entity is required to cross-reference other disclosures that provide additional detail about those amounts. These requirements are to be applied to each component of accumulated other comprehensive income. Other than the additional disclosure requirements, the adoption of these changes had no impact on the Company’s condensed consolidated financial statements.

Disclosure of accounting policy for revenue recognition. If the entity has different policies for different types of revenue transactions, the policy for each material type of transaction is generally disclosed. If a sales transaction has multiple element arrangements (for example, delivery of multiple products, services or the rights to use assets) the disclosure may indicate the accounting policy for each unit of accounting as well as how units of accounting are determined and valued. The disclosure may encompass important judgment as to appropriateness of principles related to recognition of revenue. The disclosure also may indicate the entity's treatment of any unearned or deferred revenue that arises from the transaction.
