Accounting Policies [Abstract]
Basis of Presentation	The accompanying unaudited condensed consolidated financial statements of the Company have been prepared by the Company’s management in accordance with United States generally accepted accounting principles ("U.S. GAAP") for interim financial information and applicable rules and regulations of the Securities Exchange Act of 1934. Accordingly, they do not include all of the information and footnotes required by U.S. GAAP for annual financial statements. The unaudited condensed consolidated financial statements included herein contain all adjustments (consisting of normal recurring and non-recurring adjustments) that are, in the opinion of management, necessary to present fairly the financial position at March 31, 2020 and June 30, 2019, the results of operations for the quarters and nine months ended March 31, 2020 and 2019, the statements of comprehensive (loss) income for the quarters and nine months ended March 31, 2020 and 2019, the statements of shareholders' equity for the quarters and nine months ended March 31, 2020 and 2019 and the statements of cash flows for the nine months ended March 31, 2020 and 2019. The results of operations for the quarters and nine months ended March 31, 2020 and 2019 are not necessarily indicative of the results to be expected for a full year. These financial statements should be read in conjunction with the audited consolidated financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for the fiscal year ended June 30, 2019.
Summary of Significant Accounting Policies	Except as described below, there have been no material changes to the Company’s significant accounting policies for the nine months ended March 31, 2020 from the policies described in the notes to the Company’s consolidated financial statements included in the Annual Report on Form 10-K for the fiscal year ended June 30, 2019. For a discussion of the Company’s significant accounting policies, please see the Company’s Annual Report on Form 10-K for the fiscal year ended June 30, 2019.
Cash and Cash Equivalents	The Company considers all highly-liquid investments with original maturities of three months or less, when purchased, to be cash equivalents. The Company maintains zero-balance disbursement accounts at various financial institutions at which the Company does not maintain significant depository relationships. Due to the terms of the agreements governing these accounts, the Company generally does not have the right to offset outstanding checks written from these accounts against cash on hand, and the respective institutions are not legally obligated to honor the checks until sufficient funds are transferred to fund the checks.
Long-lived Assets	The Company presents depreciation expense and intangible amortization expense on the Condensed Consolidated Income Statements. The Company's depreciation expense related to selling, general and administrative costs totaled $3.5 million and $10.5 million for the quarter and nine months ended March 31, 2020, respectively, and $3.4 million and $10.0 million for the quarter and nine months ended March 31, 2019, respectively. Depreciation expense reported as part of cost of goods sold on the Condensed Consolidated Income Statements totaled $0.6 million and $1.8 million for the quarter and nine months ended March 31, 2020, respectively, and $0.9 million and $2.9 million for the quarter and nine months ended March 31, 2019, respectively. The Company's intangible amortization expense reported on the Condensed Consolidated Income Statements relates to selling, general and administrative costs, not the cost of selling goods.
Recent Accounting Pronouncements	In February 2016, the Financial Accounting Standards Board ("FASB") issued ASU 2016-02, Leases (ASC Topic 842) requiring lessees to reflect most leases on their balance sheets and recognize expenses on their income statements in a manner similar to current guidance. Under the new guidance, lessees are required to recognize a lease liability, which is a lessee's obligation to make lease payments arising from a lease, measured on a discounted basis, and a right-of-use asset, which is an asset that represents the lessee’s right to use, or control the use of, a specified asset for the lease term. The asset is measured at the lease liability amount, adjusted for lease prepayments, lease incentives received and the lessee's initial direct costs. For leases with a lease term of 12 months or less, as long as the lease does not include options to purchase the underlying assets, lessees can elect not to recognize a lease liability and right-of-use asset. Under the new guidance, lessor accounting is largely unchanged, and the accounting for sale and leaseback transactions is simplified. This ASU is effective for the Company beginning in the first quarter of fiscal 2020. Entities are required to use the modified retrospective approach of adoption, with the option of applying the requirements of the standard either (1) retrospectively to each prior comparative reporting period presented or (2) retrospectively at the beginning of the period of adoption. The Company adopted the standard on July 1, 2019 and applied it at the beginning of the period of adoption. Therefore, upon adoption, financial information and disclosures are not updated for comparative reporting periods under the new standard. Additionally, the Company has elected the transition package of practical expedients upon adoption which, among other things, allows an entity to not reassess the historical lease classification. Upon adoption, the Company recognized right-of-use assets and corresponding lease liabilities for both operating and finance leases of approximately $37.0 million on the Condensed Consolidated Balance Sheets. The adoption of this standard was not material to the Company’s Condensed Consolidated Income Statements. See Note 11 for additional lease disclosures. In June 2016, the FASB issued ASU 2016-13, Financial Instruments - Credit Losses (ASC Topic 326). In November 2018, the FASB issued ASU 2018-19, Codification Improvements to Topic 326: Financial Instruments - Credit Losses, which provides supplemental guidance and clarification to ASU 2016-13 and must be adopted concurrently. The pronouncement revises the methodology for measuring credit losses on financial instruments and the timing of when such losses are recorded. The guidance is effective for the Company beginning in the first quarter of fiscal year 2021 with early adoption permitted. The Company is currently evaluating the potential need for a revised method to assess its allowance for doubtful accounts receivable and the related impact of this guidance on its consolidated financial statements. In August 2017, the FASB issued ASU 2017-12, Derivatives and Hedging (ASC Topic 815) that amends and simplifies guidance related to hedge accounting to more accurately portray the economics of an entity’s risk management activities in its financial statements. The standard is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. The guidance requires adoption using a modified retrospective approach. The presentation and disclosure requirements apply prospectively. The Company adopted the standard in the current fiscal year, and it had no impact on the consolidated financial statements. In August 2018, the FASB issued ASU 2018-13, Fair Value Measurement (ASC Topic 820) Disclosure Framework – Changes to the Disclosure Requirements for Fair Value Measurement. The pronouncement eliminates, modifies and adds disclosure requirements for fair value measurements. This guidance is effective for fiscal years beginning after December 15, 2019, and for interim periods within those fiscal years, with early adoption permitted. This guidance is applicable to the Company’s fiscal year beginning July 1, 2020. The Company is currently evaluating the potential impact of this guidance on its consolidated financial statements. The Company has reviewed other newly issued accounting pronouncements and concluded that they are either not applicable to its business or that no material effect is expected on its consolidated financial statements as a result of future adoption.
Revenue Recognition	The Company provides technology solutions and services from the world's leading suppliers of POS, payments, barcode, physical security, unified communications and collaboration, and telecom and cloud services. This includes hardware, related accessories and device configuration as well as software licenses, professional services and hardware support programs. The Company adopted ASC 606, effective July 1, 2018 utilizing the full retrospective method. In determining the appropriate amount of revenue to recognize, the Company applies the following five-step model: (i) identify contracts with customers; (ii) identify performance obligations in the contracts; (iii) determine the transaction price; (iv) allocate the transaction price to the performance obligations per the contracts; and (v) recognize revenue when (or as) the Company satisfies a performance obligation. The Company recognizes revenue as control of products and services are transferred to customers, which is generally at the point of shipment. The Company delivers products to customers in several ways, including: (i) shipment from the Company's warehouse, (ii) drop-shipment directly from the supplier, or (iii) electronic delivery for non-physical products. Principal versus Agent Considerations The Company is the principal for sales of all hardware, software and certain services, including self-branded warranty programs. The Company considers itself the principal in these transactions as it has control of the product or service before it is transferred to the customer. When the Company provides self-branded warranty programs, it engages a third party, generally the original equipment manufacturer, to cover the fulfillment of any obligations arising from these contracts. These revenues and associated third-party costs are amortized over the life of the contract on a straight-line basis. The Company recognizes the previously described revenue and cost of goods sold on a gross basis. The Company is the agent for third-party service contracts, including product warranties and supplier-hosted software. These service contracts are sold separately from the products, and the Company often serves as the agent for the contract on behalf of the original equipment manufacturer. The Company's responsibility is to arrange for the provision of the specified service by the original equipment manufacturer, and the Company does not control the specified service before it is transferred to the customer. Because the Company acts as an agent, revenue is recognized net of cost at the time of sale. Related to the Company’s Intelisys business, the Company acts as a master agent connecting independent sales partners with service providers or suppliers who offer telecom and cloud services to end-customers. Intelisys’ sales partners earn commission payments from those service providers or suppliers on end-customer sales. Intelisys provides commission processing services to sales partners, earning a percentage of the commission stream. Because the Company acts as an agent, revenue is recognized on a net basis. Variable Considerations For certain transactions, products are sold with a right of return and may also provide other rebates or incentives, which are accounted for as variable consideration. The Company estimates returns allowance based on historical experience and reduces revenue accordingly. The Company estimates the amount of variable consideration for rebates and incentives by using the expected value or the most likely amount to be given to the customer and reduces the revenue by those estimated amounts. These estimates are reviewed and updated as necessary at the end of each reporting period. Contract Balances The Company records contract assets and liabilities for payments received from customers in advance of services performed. These assets and liabilities are the result of the sales of the Company's self-branded warranty programs and other transactions where control has not yet passed to the customer. These amounts are immaterial to the consolidated financial statements for the periods presented.
