Basis of Presentation and Recently Issued Accounting Pronouncements	'
	1. Basis of Presentation and Recently Issued Accounting Pronouncements
	We are a leading technology provider of hardware, software and service solutions to business and government clients in North America, Europe, the Middle East, Africa and Asia-Pacific. The Company is organized in the following three operating segments, which are primarily defined by their related geographies:
	Operating Segment	Geography
	North America	United States and Canada
	EMEA	Europe, Middle East and Africa
	APAC	Asia-Pacific
	Our offerings in North America and select countries in EMEA include hardware, software and services. Our offerings in the remainder of our EMEA segment and in APAC are almost entirely software and select software-related services.
	In the opinion of management, the accompanying unaudited consolidated financial statements contain all adjustments necessary to present fairly our financial position as of September 30, 2014, our results of operations for the three and nine months ended September 30, 2014 and 2013 and our cash flows for the nine months ended September 30, 2014 and 2013. The consolidated balance sheet as of December 31, 2013 was derived from the audited consolidated balance sheet at such date. The accompanying unaudited consolidated financial statements and notes have been prepared in accordance with the rules and regulations promulgated by the Securities and Exchange Commission and consequently do not include all of the disclosures normally required by United States generally accepted accounting principles (“GAAP”).
	The results of operations for interim periods are not necessarily indicative of results for the full year, due in part to the seasonal nature of our business. These unaudited consolidated financial statements should be read in conjunction with the audited consolidated financial statements, including the related notes thereto, in our Annual Report on Form 10-K for the year ended December 31, 2013.
	The consolidated financial statements include the accounts of Insight Enterprises, Inc. and its wholly owned subsidiaries. All significant intercompany balances and transactions have been eliminated in consolidation. References to “the Company,” “Insight,” “we,” “us,” “our” and other similar words refer to Insight Enterprises, Inc. and its consolidated subsidiaries, unless the context suggests otherwise.
	The preparation of consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements. Additionally, these estimates and assumptions affect the reported amounts of net sales and expenses during the reporting period. Actual results could differ from those estimates. On an ongoing basis, we evaluate our estimates, including those related to sales recognition, anticipated achievement levels under partner funding programs, assumptions related to stock-based compensation valuation, allowances for doubtful accounts, valuation of inventories, litigation-related contingencies, valuation allowances for deferred tax assets and impairment of long-lived assets, including purchased intangibles and goodwill, if indicators of potential impairment exist.
	Recently Issued Accounting Pronouncements
	On May 28, 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2014-09, “Revenue from Contracts with Customers.” ASU 2014-09 was issued as the culmination of the joint project between the FASB and the International Accounting Standards Board (“IASB”) to clarify the principles for recognizing revenue and to develop a common revenue standard for GAAP and International Financial Reporting Standards. The core principle of the guidance is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. ASU 2014-09 is effective for the fiscal year beginning after December 15, 2016, including interim periods within that reporting period. Early adoption is not permitted. An entity may choose to adopt the new standard either retrospectively or through a cumulative effect adjustment as of the start of the first period for which it applies the new standard. We are in the process of determining the effect that the adoption of ASU 2014-09 will have on our consolidated financial statements and disclosures and have not yet selected our planned transition approach.
	In July 2013, the FASB issued ASU 2013-11, “Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists.” ASU 2013-11 clarifies guidance and eliminates diversity in practice on the presentation of unrecognized tax benefits when a net operating loss carryforward, a similar tax loss, or a tax credit carryforward exists at the reporting date. This new guidance became effective for annual reporting periods beginning after December 15, 2013 and subsequent interim periods. We applied the requirements of ASU 2013-11 prospectively beginning January 1, 2014, which resulted in a decrease to noncurrent deferred tax assets and a decrease to noncurrent reserves for uncertain tax positions of approximately $1,076,000 as of September 30, 2014. Had we applied the requirements of ASU 2013-11 retrospectively to the December 31, 2013 consolidated balance sheet, the effect would have been materially the same.
	There have been no other material changes or additions to the recently issued accounting pronouncements as previously reported in Note 1 to our Consolidated Financial Statements in Part II, Item 8 of our Annual Report on Form 10-K for the year ended December 31, 2013 that affect or may affect our financial statements.

Earnings Per Share [Abstract]	'
Net Earnings Per Share ("EPS")	'
	2. Net Earnings Per Share (“EPS”)
	Basic EPS is computed by dividing net earnings available to common stockholders by the weighted average number of common shares outstanding during each period. Diluted EPS is computed on the basis of the weighted average number of shares of common stock plus the effect of dilutive potential common shares outstanding during the period using the treasury stock method. Dilutive potential common shares include outstanding restricted stock units. A reconciliation of the denominators of the basic and diluted EPS calculations follows (in thousands, except per share data):

	For the three months ended September 30, 2014 and 2013, 5,000 and 2,000, respectively, of our restricted stock units were not included in the diluted EPS calculations because their inclusion would have been anti-dilutive. For the nine months ended September 30, 2014 and 2013, the excluded restricted stock units were 23,000 and 235,000, respectively. These share-based awards could be dilutive in the future.

	Less: current portion of revolving credit facilities		—			—
	Long-term debt	$	53,591		$	66,949
	Our senior revolving credit facility (“revolving facility”) has an aggregate U.S. dollar equivalent maximum borrowing capacity of $350,000,000. The revolving facility matures April 26, 2017, is guaranteed by the Company’s material domestic subsidiaries and is secured by a lien on substantially all of the Company’s and each guarantor’s assets. The balance of $17,000,000 outstanding at September 30, 2014 was borrowed under the prime rate option at 3.25% per annum. As of September 30, 2014, $333,000,000 was available under the revolving facility. See “Debt Covenants” below.
	On June 25, 2014, we entered into an amendment to our accounts receivable securitization financing facility (the “ABS facility”) to extend the maturity date from April 24, 2015 to June 30, 2017, to change the administrative agent and to modify fees for unused capacity under the facility. The maximum borrowing capacity of the ABS facility remained unchanged at $200,000,000. While the ABS facility has a stated maximum amount, the actual availability under the ABS facility is limited by the quantity and quality of the underlying accounts receivable. Under the ABS facility, the floating interest rate applicable at September 30, 2014 was 1.06% per annum. As of September 30, 2014, qualified receivables were sufficient to permit access to the full $200,000,000 facility amount, of which $35,000,000 was outstanding. See “Debt Covenants” below.
	Debt Covenants
	Our revolving facility and our ABS facility contain various covenants customary for transactions of this type, including limitations on the payment of dividends and the requirement that we comply with maximum leverage, minimum fixed charge and minimum asset coverage ratio requirements and meet monthly, quarterly and annual reporting requirements. If we fail to comply with these covenants, the lenders would be able to demand payment within a specified period of time. At September 30, 2014, we were in compliance with all such covenants.
	Our consolidated debt balance that can be outstanding at the end of any fiscal quarter under our revolving facility and our ABS facility is limited by certain financial covenants, particularly a maximum leverage ratio. The maximum leverage ratio is calculated as aggregate debt outstanding divided by the sum of our trailing twelve month net earnings (loss) plus (i) interest expense, excluding non-cash imputed interest on our inventory financing facility, (ii) income tax expense (benefit), (iii) depreciation and amortization and (iv) non-cash stock-based compensation (“adjusted earnings”). The maximum leverage ratio permitted under the agreements is 2.75 times trailing twelve-month adjusted earnings. A significant drop in our adjusted earnings would limit the amount of indebtedness that could be outstanding at the end of any fiscal quarter to a level that would be below our combined facility maximum amount. Based on our maximum leverage ratio as of September 30, 2014, our consolidated debt balance that could have been outstanding under our revolving facility and our ABS facility was reduced from the maximum borrowing capacity of $550,000,000 to $495,528,000, of which $52,000,000 was outstanding at September 30, 2014.
	Inventory Financing Facility
	Our inventory financing facility has a maximum borrowing capacity of $200,000,000 and matures on April 26, 2017. As of September 30, 2014 and December 31, 2013, $125,660,000 and $115,252,000, respectively, was included in accounts payable within our consolidated balance sheets related to our inventory financing facility.
	Capital Lease and Other Financing Obligations
	The present value of minimum lease payments under our capital lease, which expires on December 31, 2016, is included in our current and long-term debt balances as summarized in the table above.
	From time to time, we also enter into other financing agreements with financial intermediaries to facilitate the purchase of products from certain vendors. At September 30, 2014, amounts owed under other financing agreements of $2,002,000, which are payable in installments through August 2016, are included in our current and long-term debt balances as summarized in the table above.

	Severance Costs Expensed for 2014 Resource Actions
	During the three months ended September 30, 2014, North America and EMEA recorded severance expense totaling $177,000 and $288,000, respectively, and APAC recorded a reduction to severance and restructuring expenses of $3,000 due to a change in estimate as cash payments were made. During the nine months ended September 30, 2014, North America, EMEA and APAC recorded severance expense totaling $701,000, $1,157,000 and $106,000, respectively, related to 2014 resource actions. These charges were associated with severance for the elimination of certain positions based on a re-alignment of roles and responsibilities.
	The following table details the 2014 activity and the outstanding obligations related to the 2014 resource actions as of September 30, 2014 (in thousands):

	The remaining outstanding obligations are expected to be paid during the next 12 months and are therefore included in accrued expenses and other current liabilities.
	Severance Costs Expensed for 2013 Resource Actions
	During the year ended December 31, 2013, North America and EMEA recorded severance expense totaling $3,429,000 and $9,603,000, respectively, relating to 2013 resource actions. The charges related to a continued review of resource needs in North America and significant restructuring activities in EMEA, primarily in the United Kingdom and Germany, as we worked to rationalize our selling and administrative expenses in EMEA.
	The following table details the 2014 activity and the outstanding obligations related to the 2013 resource actions as of September 30, 2014 (in thousands):

	In North America and EMEA, adjustments were recorded to decrease severance and restructuring expense and the related severance accrual during the nine months ended September 30, 2014 due to changes in estimates as cash payments were made. The remaining outstanding obligations are expected to be paid during the next 12 months and are therefore included in accrued expenses and other current liabilities.
	Severance Costs Expensed for 2012 Resource Actions
	During the year ended December 31, 2012, North America and EMEA recorded severance expense totaling $3,022,000 and $3,973,000, respectively, associated with severance for the elimination of certain positions based on a re-alignment of roles and responsibilities. As of December 31, 2013, the total remaining obligations recorded in our North America and EMEA segments related to these resource actions were approximately $487,000 and $337,000, respectively. During the nine months ended September 30, 2014, adjustments totaling $301,000 and $96,000 were recorded in North America and EMEA, respectively, to decrease severance and restructuring expense and the related severance accrual due to changes in estimates of the remaining payouts. The outstanding obligations as of September 30, 2014 of $186,000 and $44,000 in North America and EMEA, respectively, are expected to be paid during the next 12 months and are therefore included in accrued expenses and other current liabilities.

Stock-based compensation expense in EMEA for the three months ended September 30, 2013 was negative due to the reversal of previously recognized compensation cost on RSUs forfeited by the former president of EMEA upon his separation from the Company, effective September 1, 2013, prior to the completion of the requisite service period.
	The following table summarizes our RSU activity during the nine months ended September 30, 2014:

	(a)	Includes 144,521 RSUs subject to remaining performance conditions. The number of RSUs ultimately awarded under the performance-based RSUs varies based on whether we achieve certain financial results for 2014.
	(b)	The fair value of vested RSUs represents the total pre-tax fair value, based on the closing stock price on the day of vesting, which would have been received by holders of RSUs had all such holders sold their underlying shares on that date.
	(c)	The aggregate fair value represents the total pre-tax fair value, based on our closing stock price of $22.63 as of September 30, 2014, which would have been received by holders of RSUs had all such holders sold their underlying shares on that date.
	During the nine months ended September 30, 2014 and 2013, the RSUs that vested for teammates in the United States were net-share settled such that we withheld shares with value equivalent to the teammates’ minimum statutory United States tax obligations for the applicable income and other employment taxes and remitted the corresponding cash amount to the appropriate taxing authorities. The total shares withheld during the nine months ended September 30, 2014 and 2013 of 71,223 and 136,709, respectively, were based on the value of the RSUs on their vesting date as determined by our closing stock price on such vesting date. For the nine months ended September 30, 2014 and 2013, total payments for the employees’ tax obligations to the taxing authorities were $1,662,000 and $2,756,000, respectively, and are reflected as a financing activity within the consolidated statements of cash flows. These net-share settlements had the economic effect of repurchases of common stock as they reduced the number of shares that would have otherwise been issued as a result of the vesting and did not represent a repurchase of shares or an expense to us.

	6. Impairment Loss on Assets Held for Sale
	In May 2014, we signed a lease that will result in the relocation of our sales and administrative operations that are currently housed in the property that we own in Bloomingdale, Illinois. We began marketing the property for sale in April 2014, and we expect to vacate the property in early November 2014. The property is classified as a held for sale asset, which is included in other current assets in our accompanying consolidated balance sheet as of September 30, 2014. During the nine months ended September 30, 2014, our North America operating segment recorded non-cash charges of $5,178,000, consisting of an impairment loss of $4,558,000 and accelerated depreciation of $620,000, to reduce the carrying amount of the related assets to their estimated fair value less costs to sell. The estimated fair market value was derived from Level 2 fair value inputs (see Note 9 for a description of the categories of fair value inputs), which included a current market analysis indicating the price per square foot of previous sale transactions involving comparable property in the Bloomingdale area. The charges are included in selling and administrative expenses in our accompanying consolidated statements of operations.

	7. Income Taxes
	Our effective tax rate for the three and nine months ended September 30, 2014 was 34.1% and 37.4%, respectively. For the three months ended September 30, 2014, our effective tax rate was lower than the United States federal statutory rate of 35.0% due primarily to the recognition of certain tax benefits related to the release of reserves for specific uncertain tax positions during the quarter and to lower taxes on earnings in foreign jurisdictions. For the nine months ended September 30, 2014, our effective tax rate was higher than the United States federal statutory rate of 35.0% due primarily to state income taxes net of federal benefit and other nondeductible expenses, partially offset by lower taxes on earnings in foreign jurisdictions and the recognition of tax benefits related to the release of reserves for uncertain tax positions during the third quarter of 2014.
	Our effective tax rate for the three and nine months ended September 30, 2013 was 37.8% and 37.2%, respectively. For the three and nine months ended September 30, 2013, our effective tax rate was higher than the United States federal statutory rate of 35.0% due primarily to an increase in the valuation allowance for deferred tax assets related to certain foreign operating losses and foreign tax credits and to state income taxes, net of federal benefit. These increases in the effective rate were partially offset by the effect of lower taxes on earnings in foreign jurisdictions. The nine month rate was slightly lower than the rate for the third quarter due to the recognition of certain tax benefits related to the re-measurement or settlement of specific uncertain tax positions during the first quarter of 2013.
	As of September 30, 2014 and December 31, 2013, we had approximately $4,151,000 and $4,546,000, respectively, of unrecognized tax benefits. Of these amounts, approximately $288,000 and $364,000, respectively, related to accrued interest.
	Several of our subsidiaries are currently under audit for tax years 2006 through 2013. It is reasonably possible that the examination phase of these audits may conclude in the next 12 months and that the related unrecognized tax benefits for uncertain tax positions may change, potentially having a material effect on our effective tax rate. However, based on the status of the various examinations in multiple jurisdictions, an estimate of the range of reasonably possible outcomes cannot be made at this time.

	On October 30, 2013, we announced that our Board of Directors had authorized a repurchase of up to $50,000,000 of our common stock. Any share repurchases may be made on the open market, through block trades, through 10b5-1 plans or otherwise. The amount of shares purchased and the timing of the purchases will be based on working capital requirements, general business conditions and other factors. We intend to retire the repurchased shares. Under this repurchase authorization, we did not repurchase any shares of our common stock during the three months ended September 30, 2014. We purchased 1,272,299 shares of our common stock on the open market at a total cost of approximately $29,652,000 (an average price of $23.31 per share) during the nine months ended September 30, 2014, and all shares repurchased through September 30, 2014 have been retired. As of September 30, 2014, approximately $12,574,000 remains available for repurchases of our common stock under this repurchase program.
	During the comparative nine months ended September 30, 2013, we purchased 2,646,722 shares of our common stock on the open market at a total cost of approximately $50,000,000 (an average price of $18.89 per share) under a previous repurchase program that was authorized in February 2013 and completed in May 2013. All shares repurchased were retired.

	11. Commitments and Contingencies
	Contractual
	In the ordinary course of business, we issue performance bonds to secure our performance under certain contracts or state tax requirements. As of September 30, 2014, we had approximately $637,000 of performance bonds outstanding. These bonds are issued on our behalf by a surety company on an unsecured basis; however, if the surety company is ever required to pay out under the bonds, we have contractually agreed to reimburse them.
	Employment Contracts and Severance Plans
	We have employment contracts with, and plans covering, certain officers and management teammates under which severance payments would become payable in the event of specified terminations without cause or terminations under certain circumstances after a change in control. In addition, vesting of stock-based compensation would accelerate following a change in control. If severance payments under the current employment agreements or plan payments were to become payable, the severance payments would generally range from three to twenty-four months of salary.
	Indemnifications
	From time to time, in the ordinary course of business, we enter into contractual arrangements under which we agree to indemnify either our clients or third-party service providers from certain losses incurred relating to services performed on our behalf or for losses arising from defined events, which may include litigation or claims relating to past performance. These arrangements include, but are not limited to, the indemnification of our clients for certain claims arising out of our performance under our sales contracts, the indemnification of our landlords for certain claims arising from our use of leased facilities and the indemnification of the lenders that provide our credit facilities for certain claims arising from their extension of credit to us. Such indemnification obligations may not be subject to maximum loss clauses.
	Management believes that payments, if any, related to these indemnifications are not probable at September 30, 2014. Accordingly, we have not accrued any liabilities related to such indemnifications in our consolidated financial statements.
	We have entered into separate indemnification agreements with certain of our executive officers and with each of our directors. These agreements require us, among other requirements, to indemnify such officers and directors against expenses (including attorneys’ fees), judgments and settlements incurred by such individual in connection with any action arising out of such individual’s status or service as our executive officer or director (subject to exceptions such as where the individual failed to act in good faith or in a manner the individual reasonably believed to be in, or not opposed to, the best interests of the Company) and to advance expenses incurred by such individual with respect to which such individual may be entitled to indemnification by us. There are no pending legal proceedings that involve the indemnification of any of the Company’s directors or officers.
	Contingencies Related to Third-Party Review
	From time to time, we are subject to potential claims and assessments from third parties. We are also subject to various governmental, client and vendor audits. We continually assess whether or not such claims have merit and warrant accrual. Where appropriate, we accrue estimates of anticipated liabilities in the consolidated financial statements. Such estimates are subject to change and may affect our results of operations and our cash flows.
	Legal Proceedings
	We are party to various legal proceedings arising in the ordinary course of business, including preference payment claims asserted in client bankruptcy proceedings, indemnification claims, claims of alleged infringement of patents, trademarks, copyrights and other intellectual property rights, claims of alleged non-compliance with contract provisions and claims related to alleged violations of laws and regulations. Many of these proceeding are at preliminary stages, and many of these proceedings seek an indeterminate amount of damages. We regularly evaluate the status of the legal proceedings in which we are involved to assess whether a loss is probable or there is a reasonable possibility that a loss, or an additional loss, may have been incurred and determine if accruals are appropriate. If accruals are not appropriate, we further evaluate each legal proceeding to assess whether an estimate of possible loss or range of possible loss can be made for disclosure. Although litigation is inherently unpredictable, we believe that we have adequate provisions for any probable and estimable losses. It is possible, nevertheless, that our consolidated financial position, results of operations or liquidity could be materially and adversely affected in any particular period by the resolution of a legal proceeding. Legal expenses related to defense, negotiations, settlements, rulings and advice of outside legal counsel are expensed as incurred.
	In August 2010, in connection with an investigation being conducted by the United States Department of Justice, our subsidiary, Calence, LLC (“Calence”), received a subpoena from the Office of the Inspector General of the Federal Communications Commission requesting documents and information related to the expenditure of funds under the E-Rate program, which provides schools and libraries with discounts to obtain affordable telecommunications and internet access and related hardware and software. The basis of the investigation was a qui tam lawsuit filed in the United States District Court for the Southern District of Texas by a contractor who provided services to the former owners of Calence. The lawsuit, designated United States ex rel. Shupe v. Cisco Systems, Inc., Avnet, Inc. and Calence, LLC, alleged violations of the False Claims Act and sought various remedies including treble damages and civil penalties. An appeal from a District Court order denying motions to dismiss was filed with the Fifth Circuit, and in July 2014 the Fifth Circuit reversed the District Court’s decision and remanded the case to the District Court for further proceedings consistent with its decision regarding E-Rate claims under the False Claims Act. In August 2014, the District Court dismissed the case in its entirety.
	The Company is not involved in any pending or threatened legal proceedings that it believes could reasonably be expected to have a material adverse effect on its financial condition, results of operations or liquidity.

	All significant intercompany transactions are eliminated upon consolidation, and there are no differences between the accounting policies used to measure profit and loss for our segments and on a consolidated basis. Net sales are defined as net sales to external clients. None of our clients exceeded ten percent of consolidated net sales for the three or nine months ended September 30, 2014 or 2013.
	A portion of our operating segments’ selling and administrative expenses arise from shared services and infrastructure that we have historically provided to them in order to realize economies of scale and to use resources efficiently. These expenses, collectively identified as corporate charges, include senior management expenses, internal audit, legal, tax, insurance services, treasury and other corporate infrastructure expenses. Charges are allocated to our operating segments, and the allocations have been determined on a basis that we considered to be a reasonable reflection of the utilization of services provided to or benefits received by the operating segments.

	Recently Issued Accounting Pronouncements
	On May 28, 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2014-09, “Revenue from Contracts with Customers.” ASU 2014-09 was issued as the culmination of the joint project between the FASB and the International Accounting Standards Board (“IASB”) to clarify the principles for recognizing revenue and to develop a common revenue standard for GAAP and International Financial Reporting Standards. The core principle of the guidance is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. ASU 2014-09 is effective for the fiscal year beginning after December 15, 2016, including interim periods within that reporting period. Early adoption is not permitted. An entity may choose to adopt the new standard either retrospectively or through a cumulative effect adjustment as of the start of the first period for which it applies the new standard. We are in the process of determining the effect that the adoption of ASU 2014-09 will have on our consolidated financial statements and disclosures and have not yet selected our planned transition approach.
	In July 2013, the FASB issued ASU 2013-11, “Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists.” ASU 2013-11 clarifies guidance and eliminates diversity in practice on the presentation of unrecognized tax benefits when a net operating loss carryforward, a similar tax loss, or a tax credit carryforward exists at the reporting date. This new guidance became effective for annual reporting periods beginning after December 15, 2013 and subsequent interim periods. We applied the requirements of ASU 2013-11 prospectively beginning January 1, 2014, which resulted in a decrease to noncurrent deferred tax assets and a decrease to noncurrent reserves for uncertain tax positions of approximately $1,076,000 as of September 30, 2014. Had we applied the requirements of ASU 2013-11 retrospectively to the December 31, 2013 consolidated balance sheet, the effect would have been materially the same.
	There have been no other material changes or additions to the recently issued accounting pronouncements as previously reported in Note 1 to our Consolidated Financial Statements in Part II, Item 8 of our Annual Report on Form 10-K for the year ended December 31, 2013 that affect or may affect our financial statements.
