Summary Of Significant Accounting Policies [Abstract]
Summary Of Significant Accounting Policies	1. Summary of Significant Accounting Policies *Basis of Presentation* The accompanying unaudited condensed consolidated financial statements of BSQUARE Corporation ("BSQUARE"), have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission for interim financial reporting and include the accounts of BSQUARE and our wholly owned subsidiaries. Certain information and footnote disclosures normally included in the annual consolidated financial statements prepared in accordance with U.S. generally accepted accounting principles ("GAAP") have been condensed or omitted pursuant to such rules and regulations. In our opinion, the unaudited consolidated financial statements include all material adjustments, all of which are of a normal and recurring nature, necessary to present fairly our financial position as of September 30, 2011 and our operating results and cash flows for the three and nine months ended September 30, 2011 and 2010. The accompanying financial information as of December 31, 2010 is derived from audited financial statements. Preparing financial statements requires us to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenue and expenses. Examples include provisions for bad debts and income taxes, estimates of progress on professional engineering service arrangements and bonus accruals. Actual results may differ from these estimates. Interim results are not necessarily indicative of results for a full year. The information included in this Quarterly Report on Form 10-Q should be read in conjunction with our Annual Report on Form 10-K for the year ended December 31, 2010. All intercompany balances have been eliminated. *Recently Issued Accounting Standards* In June 2011, the Financial Accounting Standards Board ("FASB"), issued Accounting Standards Update ("ASU") No. 2011-05, "Comprehensive Income: Presentation of Comprehensive Income." This new standard requires the presentation of comprehensive income, the components of net income and the components of other comprehensive income either in a single continuous statement of comprehensive income or in two separate but consecutive statements. The new standard also requires presentation of adjustments for items that are reclassified from other comprehensive income to net income in the statement where the components of net income and the components of other comprehensive income are presented. The updated guidance is effective on a retrospective basis for financial statements issued for interim and annual periods beginning after December 15, 2011. Early adoption is permitted. This guidance affects presentation only and will have no effect on our financial condition, results of operations or cash flows. In May 2011, the FASB amended ASC 820, "Fair Value Measurements." This amendment is intended to result in convergence between U.S. GAAP and International Financial Reporting Standards requirements for measurement of and disclosures about fair value. This guidance clarifies the application of existing fair value measurements and disclosures, and changes certain principles or requirements for fair value measurements and disclosures. The updated guidance is effective on a prospective basis for financial statements issued for interim and annual periods beginning after December 15, 2011. The adoption of this guidance will not have a material impact on our consolidated financial statements. In September 2011, the FASB issued ASU No. 2011-08, "Testing Goodwill for Impairment." ASU 2011-08 simplifies the goodwill impairment assessment by permitting a company to make a qualitative assessment of whether it is more likely than not that a reporting unit's fair value is less than its carrying amount before applying the two-step goodwill impairment test. If the conclusion is that it is more likely than not that the fair value of a reporting unit is less than its carrying amount, the company would be required to conduct the current two-step goodwill impairment test. Otherwise, it would not need to apply the two-step test. ASU 2011-08 is effective for annual and interim goodwill impairment tests performed for fiscal years beginning after December 15, 2011. Early adoption is permitted. We don't expect the adoption of ASU 2011-08 to have a material impact on our financial position, results of operations, or cash flows. *Income or Loss Per Share* Basic income or loss per share is computed using the weighted average number of common shares outstanding during the period, and excludes any dilutive effects of common stock equivalent shares, such as stock options, restricted stock awards ("RSAs") and restricted stock units ("RSUs"). RSAs are considered outstanding and included in the computation of basic income or loss per share when underlying restrictions expire and the awards are no longer forfeitable. RSUs are considered outstanding and included in the computation of basic income or loss per share only when vested. Diluted income or loss per share is computed using the weighted average number of common shares outstanding and common stock equivalent shares outstanding during the period using the treasury stock and if-converted method. Common stock equivalent shares are excluded from the computation if their effect is anti-dilutive.

1. Summary of Significant Accounting Policies

Basis of Presentation

The accompanying unaudited condensed consolidated financial statements of BSQUARE Corporation ("BSQUARE"), have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission for interim financial reporting and include the accounts of BSQUARE and our wholly owned subsidiaries. Certain information and footnote disclosures normally included in the annual consolidated financial statements prepared in accordance with U.S. generally accepted accounting principles ("GAAP") have been condensed or omitted pursuant to such rules and regulations. In our opinion, the unaudited consolidated financial statements include all material adjustments, all of which are of a normal and recurring nature, necessary to present fairly our financial position as of September 30, 2011 and our operating results and cash flows for the three and nine months ended September 30, 2011 and 2010. The accompanying financial information as of December 31, 2010 is derived from audited financial statements. Preparing financial statements requires us to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenue and expenses. Examples include provisions for bad debts and income taxes, estimates of progress on professional engineering service arrangements and bonus accruals. Actual results may differ from these estimates. Interim results are not necessarily indicative of results for a full year. The information included in this Quarterly Report on Form 10-Q should be read in conjunction with our Annual Report on Form 10-K for the year ended December 31, 2010. All intercompany balances have been eliminated.

The new standard also requires presentation of adjustments for items that are reclassified from other comprehensive income to net income in the statement where the components of net income and the components of other comprehensive income are presented. The updated guidance is effective on a retrospective basis for financial statements issued for interim and annual periods beginning after December 15, 2011. Early adoption is permitted. This guidance affects presentation only and will have no effect on our financial condition, results of operations or cash flows.

Income or Loss Per Share

Basic income or loss per share is computed using the weighted average number of common shares outstanding during the period, and excludes any dilutive effects of common stock equivalent shares, such as stock options, restricted stock awards ("RSAs") and restricted stock units ("RSUs"). RSAs are considered outstanding and included in the computation of basic income or loss per share when underlying restrictions expire and the awards are no longer forfeitable. RSUs are considered outstanding and included in the computation of basic income or loss per share only when vested. Diluted income or loss per share is computed using the weighted

average number of common shares outstanding and common stock equivalent shares outstanding during the period using the treasury stock and if-converted method. Common stock equivalent shares are excluded from the computation if their effect is anti-dilutive.
