Organization Consolidation And Presentation Of Financial Statements [Abstract]
Basis of Presentation and Recently Issued Accounting Standards	1. Basis of Presentation and Recently Issued Accounting Standards We empower organizations of all sizes with Insight Intelligent Technology Solutions TM Operating Segment Geography North America United States and Canada EMEA Europe, Middle East and Africa APAC Asia-Pacific Our offerings in North America and certain countries in EMEA and APAC include hardware, software and services. Our offerings in the remainder of our EMEA and APAC segments consist of largely software and certain 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 June 30, 2019 and our results of operations for the three and six months ended June 30, 2019 and 2018 and cash flows for the six months ended June 30, 2019 and 2018. The consolidated balance sheet as of December 31, 2018 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, 2018. Our results of operations include the results of Cardinal Solutions Group, Inc. (“Cardinal”) from its acquisition date of August 1, 2018. 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. 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 obligations, 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 Standards In June 2016, the Financial Accounting Standards Board’s (“FASB”) issued Accounting Standard Update (“ASU”) No. 2016-13, “Financial Instruments – Credit Losses.” The new standard is intended to provide financial statement users with more decision-useful information about the expected credit losses on financial instruments and other commitments to extend credit held at each reporting date. The new standard is effective for interim and annual periods beginning after December 15, 2019, and early adoption is permitted. We will adopt the new standard as of January 1, 2020 and do not expect the adoption to have a material effect on our consolidated financial statements. In April 2019, the FASB issued ASU No. 2019-04, “Codification Improvements to Topic 326, Financial Instruments – Credit Losses, Topic 815, Derivatives and Hedging, and Topic 825, Financial Instruments.” The new standard provides changes for how a company considers expected recoveries and contractual extensions or renewal options when estimating expected credit losses. The new standard is effective with the adoption of ASU No. 2016-13. We will adopt the new standard as of January 1, 2020 and do not expect the adoption to have a material effect on our consolidated financial statements. Effective January 1, 2019, we adopted the FASB ASU No. 2016-02— Leases (Topic 842) Adoption of the new standard resulted in the recording of additional net operating lease ROU assets and lease liabilities of $65,922,000 and $70,512,000, respectively, as of January 1, 2019. The difference between the additional lease assets and lease liabilities reflected existing accrued and prepaid rent balances that were reclassified to the operating lease ROU asset at January 1, 2019. The standard did not materially impact our consolidated net earnings and had no impact on cash flows. There have been no other material changes in or additions to the recently issued accounting standards 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, 2018 that affect or may affect our current financial statements.

Leases

Leases	6 Months Ended
	Jun. 30, 2019
Leases [Abstract]
Leases	2. Leases We lease office space, distribution centers, land, vehicles and equipment. Lease agreements with an initial term of 12 months or less are not recorded on the balance sheet; we recognize lease expense for these leases on a straight-line basis over the lease term. Certain lease agreements include one or more options to renew, with renewal terms that can extend the lease term from one to five years The exercise of lease renewal options is at our sole discretion. Certain of our lease agreements include rental payments adjus ted periodically for inflation. Our lease agreements do not contain any material residual value guarantees or material restrictive covenants. Significant Accounting Policy We determine if a contract or arrangement is, or contains, a lease at inception. Balances related to operating leases are included in other assets, other current liabilities, and other liabilities in our consolidated balance sheet. Balances related to financing leases are included in property and equipment, current portion of long-term debt, and long-term debt in our consolidated balance sheet. ROU assets represent our right to use an underlying asset for the lease term and lease liabilities represent our obligation to make lease payments arising from the lease. Operating lease ROU assets and liabilities are recognized at commencement date based on the present value of lease payments over the lease term. As most of our leases do not provide an implicit rate, we use our incremental borrowing rate based on the information available at commencement date in determining the present value of lease payments. We use the implicit rate when readily determinable. The operating lease ROU asset includes any prepaid lease payments and additional direct costs and excludes lease incentives. Our lease terms may include options to extend or terminate the lease when it is reasonably certain that we will exercise that option. The following table provides information about the financial statement classification of our lease balances reported within the consolidated balances sheets as of June 30, 2019 and January 1, 2019 (in thousands): Leases Classification June 30, 2019 January 1, 2019 Assets Operating lease assets Other assets $ 60,286 $ 65,922 Finance lease assets Property and equipment (a) 1,350 1,693 Total lease assets $ 61,636 $ 67,615 Liabilities Current Operating lease liabilities Accrued expenses and other current liabilities $ 15,096 $ 15,788 Finance lease liabilities Current portion of long-term debt 1,421 1,399 Non-current Operating lease liabilities Other liabilities 50,252 54,724 Finance lease liabilities Long-term debt 930 1,521 Total lease liabilities $ 67,699 $ 73,432 (a) Recorded net of accumulated amortization of $344,000 as of June 30, 2019 and there is no accumulated amortization as of January 1, 2019.

Rental expense for these third-party operating leases was $20,114,000, $19,126,000 and $14,444,000 in 2018, 2017 and 2016, respectively, and is included in selling and administrative expenses.

Earnings Per Share [Abstract]
Net Earnings Per Share ("EPS")	4 . 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 (“RSUs”). A reconciliation of the denominators of the basic and diluted EPS calculations follows (in thousands, except per share data): Three Months Ended June 30, Six Months Ended June 30, 2019 2018 2019 2018 Numerator: Net earnings $ 49,998 $ 51,479 $ 89,325 $ 84,482 Denominator: Weighted average shares used to compute basic EPS 35,772 35,483 35,691 35,698 Dilutive potential common shares due to dilutive RSUs, net of tax effect 339 332 416 341 Weighted average shares used to compute diluted EPS 36,111 35,815 36,107 36,039 Net earnings per share: Basic $ 1.40 $ 1.45 $ 2.50 $ 2.37 Diluted $ 1.38 $ 1.44 $ 2.47 $ 2.34 For the three and six months ended June 30, 2019, 1,000 and 83,000, respectively, of our RSUs were not included in the diluted EPS calculations because their inclusion would have been anti-dilutive. These share-based awards could be dilutive in the future. There were 13,000 and 17,000 anti-dilutive RSUs for the three and six months ended June 30, 2018, respectively.

Our accounts receivable securitization financing facility (the “ABS facility”) has a maximum aggregate borrowing availability of $250,000,000, and matures on June 23, 2021. 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. As of June 30, 2019 , qualified receivables were sufficient to permit access to the full $ facility amount , of which $ was outstanding . 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, (iv) non-cash stock-based compensation, (v) extraordinary or non-recurring non-cash losses or expenses and (vi) certain cash restructuring and acquisition-related charges and synergies, not to exceed a specified cap (“adjusted earnings”). The maximum leverage ratio permitted under the facilities is currently 3.0 Inventory Financing Facility As of June 30, 2019, our inventory financing facility had a maximum borrowing capacity of $400,000,000, of which $260,890,000 was outstanding at June 30, 2019. The inventory financing facility matures on June 23, 2021. If balances are not paid within stated vendor terms, they will accrue interest at prime plus 1.25%. Amounts outstanding under this facility are classified separately as accounts payable – inventory financing facility in the accompanying consolidated balance sheets.

Income Tax Disclosure [Abstract]
Income Taxes	8 . Income Taxes Our effective tax rate for the three and six months ended June 30, 2019 was 25.9% and 24.9%, respectively. For the three months ended June 30, 2019, our effective tax rate was higher than the United States federal statutory rate of 21.0% due primarily to state income taxes, net of federal benefit, higher taxes on earnings in foreign jurisdictions, and the effect of non-deductible acquisition-related expenses partially offset by the recognition of tax benefits related to research and development activities. For the six months ended June 30, 2019, our effective tax rate was higher than the United States federal statutory rate of 21.0% due primarily to state income taxes, net of federal benefit, and higher taxes on earnings in foreign jurisdictions partially offset by tax benefits on the settlement of employee share-based awards and the recognition of tax benefits related to research and development activities. Our effective tax rate for both the three and six months ended June 30, 2018 was 25.9%. For the three and six months ended June 30, 2018, our effective tax rate was higher than the United States federal statutory rate of 21.0% due primarily to state income taxes net of federal benefit. As of June 30, 2019, and December 31, 2018, we had approximately $8,337,000 and $6,849,000, respectively, of unrecognized tax benefits. Of these amounts, approximately $440,000 and $313,000, respectively, related to accrued interest. In the future, if recognized, the liability associated with uncertain tax positions would affect our effective tax rate. We do not believe there will be any changes over the next 12 months that would have a material effect on our effective tax rate. Several of our subsidiaries are currently under audit for tax years 2012 through 2017. Although the timing of the resolutions and/or closures of audits is highly uncertain, it is reasonably possible that the examination phase of these audits may be concluded within the next 12 months, which could increase or decrease the balance of our gross unrecognized tax benefits. 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, but the estimated effect on our income tax expense and net earnings is not expected to be significant.

Share Repurchase Program	9 . Share Repurchase Program On February 13, 2018, our Board of Directors authorized the repurchase of up to $50,000,000 of our common stock. Our share repurchases will be made on the open market, subject to Rule 10b-18 or in privately negotiated transactions, through block trades, through 10b5-1 plans or otherwise, at management’s discretion. The amount of shares purchased and the timing of the purchases will be based on market conditions, working capital requirements, general business conditions and other factors. We intend to retire the repurchased shares. During the six months ended June 30, 2019, we did no repurchased 641,211 shares of our common stock on the open market at a total cost of approximately $22,069,000 (an average price of $34.42 per share). All shares repurchased were retired.

Commitments and Contingencies	6 Months Ended

Commitments And Contingencies Disclosure [Abstract]
Commitments and Contingencies	10 . 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 June 30, 2019, we had approximately $3,939,000 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 the surety company. Management believes that payments, if any, related to these performance bonds are not probable at June 30, 2019 . Accordingly, we have not accrued any liabilities related to such performance bonds in our consolidated financial statements. Employment Contracts and Severance Plans We have employment contracts with, and severance 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 outstanding nonvested RSUs 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 June 30, 2019. 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 partner 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 From time to time, 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. 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. The Company is not involved in any pending or threatened legal proceedings that it believes would reasonably be expected to have a material adverse effect on its business, financial condition or results of operations.

Our offerings in the remainder of our EMEA and APAC segments are largely software and certain software-related services. The following table summarizes net sales by offering for North America, EMEA and APAC for the three and six months ended June 30, 2019 and 2018 (in thousands): North America EMEA APAC Three Months Ended June 30, Three Months Ended June 30, Three Months Ended June 30, Sales Mix 2019 2018 2019 2018 2019 2018 Hardware $ 935,792 $ 898,143 $ 142,951 $ 171,336 $ 9,979 $ 9,318 Software 289,874 307,570 190,086 193,116 25,653 39,340 Services 179,841 163,053 46,137 45,084 15,708 13,910 $ 1,405,507 $ 1,368,766 $ 379,174 $ 409,536 $ 51,340 $ 62,568 North America EMEA APAC Six Months Ended June 30, Six Months Ended June 30, Six Months Ended June 30, Sales Mix 2019 2018 2019 2018 2019 2018 Hardware $ 1,684,129 $ 1,771,485 $ 314,476 $ 358,346 $ 16,497 $ 16,478 Software 611,953 568,629 373,234 383,318 60,718 78,359 Services 351,866 307,032 81,639 75,006 26,975 24,711 $ 2,647,948 $ 2,647,146 $ 769,349 $ 816,670 $ 104,190 $ 119,548 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 or 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 six months ended June 30, 2019 or 2018. A portion of our operating segments’ selling and administrative expenses arise from shared services and infrastructure that we have historically provide d to them in order to realize economies of scale and to use resources efficiently .

Business Combinations [Abstract]
Acquisition	12. Cardinal Effective August 1, 2018, we acquired 100 percent of the issued and outstanding shares of Cardinal, a digital solutions provider based in Cincinnati, Ohio, with offices across the Midwest and Southeast United States, for a cash purchase price, net of cash acquired, of approximately $78,400,000, including final working capital and tax gross up adjustments. Cardinal provides technology solutions to digitally transform organizations through their expertise in mobile applications development, Internet of Things and cloud enabled business intelligence. We believe that this acquisition strengthens our services capabilities and will bring value to our clients within our digital innovation services solution offering. The fair value of net assets acquired was approximately $42,360,000, including $27,540,000 of identifiable intangible assets, consisting primarily of customer relationships that will be amortized using the straight line method over the estimated economic life of ten years. The preliminary purchase price was allocated using the information currently available. We finalized the fair value assumptions for identifiable intangible assets acquired in the fourth quarter of 2018. Goodwill acquired approximated $36,040,000 which was recorded in our North America operating segment. The goodwill is tax deductible. The working capital adjustment in the amount of $762,000 was finalized in the fourth quarter of 2018 and paid in January 2019. Additionally, we finalized the purchase price allocation when the tax gross up adjustment of $2,600,000 was agreed upon in April 2019. This resulted in a reduction of the previously recorded purchase price of $400,000.

Organization Consolidation And Presentation Of Financial Statements [Abstract]
Recently Issued Accounting Standards	Recently Issued Accounting Standards In June 2016, the Financial Accounting Standards Board’s (“FASB”) issued Accounting Standard Update (“ASU”) No. 2016-13, “Financial Instruments – Credit Losses.” The new standard is intended to provide financial statement users with more decision-useful information about the expected credit losses on financial instruments and other commitments to extend credit held at each reporting date. The new standard is effective for interim and annual periods beginning after December 15, 2019, and early adoption is permitted. We will adopt the new standard as of January 1, 2020 and do not expect the adoption to have a material effect on our consolidated financial statements. In April 2019, the FASB issued ASU No. 2019-04, “Codification Improvements to Topic 326, Financial Instruments – Credit Losses, Topic 815, Derivatives and Hedging, and Topic 825, Financial Instruments.” The new standard provides changes for how a company considers expected recoveries and contractual extensions or renewal options when estimating expected credit losses. The new standard is effective with the adoption of ASU No. 2016-13. We will adopt the new standard as of January 1, 2020 and do not expect the adoption to have a material effect on our consolidated financial statements. Effective January 1, 2019, we adopted the FASB ASU No. 2016-02— Leases (Topic 842) Adoption of the new standard resulted in the recording of additional net operating lease ROU assets and lease liabilities of $65,922,000 and $70,512,000, respectively, as of January 1, 2019. The difference between the additional lease assets and lease liabilities reflected existing accrued and prepaid rent balances that were reclassified to the operating lease ROU asset at January 1, 2019. The standard did not materially impact our consolidated net earnings and had no impact on cash flows. There have been no other material changes in or additions to the recently issued accounting standards 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, 2018 that affect or may affect our current financial statements.
Significant Accounting Policy - Leases	Significant Accounting Policy We determine if a contract or arrangement is, or contains, a lease at inception. Balances related to operating leases are included in other assets, other current liabilities, and other liabilities in our consolidated balance sheet. Balances related to financing leases are included in property and equipment, current portion of long-term debt, and long-term debt in our consolidated balance sheet. ROU assets represent our right to use an underlying asset for the lease term and lease liabilities represent our obligation to make lease payments arising from the lease. Operating lease ROU assets and liabilities are recognized at commencement date based on the present value of lease payments over the lease term. As most of our leases do not provide an implicit rate, we use our incremental borrowing rate based on the information available at commencement date in determining the present value of lease payments. We use the implicit rate when readily determinable. The operating lease ROU asset includes any prepaid lease payments and additional direct costs and excludes lease incentives. Our lease terms may include options to extend or terminate the lease when it is reasonably certain that we will exercise that option.
