Accounting Policies [Abstract]
Basis of Presentation	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 ("US 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 US 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 as of September 30, 2017 and June 30, 2017, the results of operations for the quarters ended September 30, 2017 and 2016, the statements of comprehensive income for the quarters ended September 30, 2017 and 2016, and the statements of cash flows for the quarters ended September 30, 2017 and 2016. The results of operations for the quarters ended September 30, 2017 and 2016 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, 2017.
Significant Accounting Policies	Summary of Significant Accounting Policies Except as described below, there have been no material changes to the Company’s significant accounting policies for the quarter ended September 30, 2017 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, 2017. 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, 2017.
Cash and Cash Equivalents	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. As a result, checks released but not yet cleared from these accounts in the amounts of $10.4 million and $8.3 million are included in accounts payable as of September 30, 2017 and June 30, 2017, respectively.
Long-lived Assets	Long-lived Assets The Company presents depreciation expense and intangible amortization expense individually on the Condensed Consolidated Income Statements. The Company's depreciation expense related to selling, general and administrative costs totaled $3.2 million and $2.1 million for the quarters ended September 30, 2017 and 2016. Depreciation expense reported as part of cost of goods sold on the Condensed Consolidated Income Statements totaled $0.6 million for the quarter ended September 30, 2017. There was no depreciation expense reported as part of cost of goods sold prior to the acquisition of POS Portal on July 31, 2017. The Company's amortization expense of $5.0 million and $3.2 million for the quarters ended September 30, 2017 and 2016 relate to selling, general and administrative costs, not the cost of selling goods.
Recent Accounting Pronouncements	Recent Accounting Pronouncements In May 2014, the Financial Accounting Standards Board ("FASB") issued a comprehensive new revenue recognition standard for contracts with customers that will supersede most current revenue recognition guidance, including industry-specific guidance. The core principle of this standard 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. To achieve this core principle, the standard provides a five-step analysis of transactions to determine when and how revenue is recognized. Other major provisions include the capitalization and amortization of certain contract costs, ensuring the time value of money is considered in the transaction price, and allowing estimates of variable consideration to be recognized before contingencies are resolved in certain circumstances. This guidance also requires enhanced disclosures regarding the nature, amount, timing and uncertainty of revenue and cash flows arising from an entity’s contracts with customers. The new standard is effective for fiscal years, and interim periods within those years, beginning after December 15, 2017. The standard permits the use of either the retrospective or cumulative effect transition method. This guidance will be applicable to the Company for the fiscal year beginning July 1, 2018. We are currently in the process of evaluating the impact of this guidance on our consolidated financial results to determine the appropriate transition method for the Company. We have engaged a third-party consultant to assist with developing a multi-phase plan to assess the impact of adoption. We are currently in the process of reviewing and analyzing our business processes and current material contracts. In February 2016, the FASB issued Accounting Standards Update ("ASU") 2016-02, Leases (Topic 842) requiring lessees to reflect most leases on their balance sheets and recognize expenses on their income statements. Under the new guidance, lessees will be 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 will be 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. The standard is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. This guidance will be applicable to the Company for the fiscal year beginning July 1, 2019. The guidance must be adopted using a modified retrospective approach for leases that exist or are entered into after the beginning of the earliest comparative period in the financial statements. The Company is currently evaluating the impact on its consolidated financial statements upon the adoption of this new guidance. In March 2016, the FASB issued ASU 2016-09, Compensation - Stock Compensation (Topic 718) effective for fiscal years beginning after December 15, 2016, including interim periods within those fiscal years. This guidance was adopted by the Company prospectively on July 1, 2017. The new standard simplifying several aspects of the accounting for employee share-based payment transactions, including the accounting for income taxes, forfeitures and statutory withholding requirements, as well as classification in the statement of cash flows. Under the new guidance, an entity will recognize all excess tax benefits and tax deficiencies as income tax expense or benefit in the income statement. This change eliminates the current practice of recognizing excess tax benefits in additional paid-in-capital ("APIC") and tax deficiencies in APIC to the extent that there is a sufficient APIC pool related to previously recognized excess tax benefits. In addition, excess tax benefits and tax deficiencies are considered discrete items in the reporting period they occur and are not included in the estimate of an entity’s annual effective tax rate. See Note 11 - Income Taxes for a discussion on the tax impact of the new guidance on the Company's consolidated financial statements for the quarter ended September 30, 2017. As for classification on the statement of cash flows, excess tax benefits will no longer represent a financing activity since they are recognized in the income statement and will appropriately be classified as an operating activity. See the Condensed Consolidated Statements of Cash Flows for the three months ended September 30, 2017 for the prospective presentation of classifying excess tax benefits as an operating activity, not a financing activity as in prior years. The ASU allows an entity to elect as an accounting policy either to continue to estimate the total number of awards for which the requisite service period will not be rendered (as currently required) or to account for forfeitures when they occur. The Company elected to maintain its accounting policy to estimate to the total number of forfeitures for stock awards granted. In regards to statutory withholding requirements, the new guidance stipulates that the net settlement of an award would not result, by itself, in liability classification of the award provided that the amount withheld for taxes does not exceed the maximum statutory tax rate in the employees’ relevant tax jurisdictions. In August 2016, the FASB issued ASU 2016-15, Statement of Cash Flows (Topic 230) intended to reduce diversity in practice of how certain cash receipts and cash payments are presented and classified in the statement of cash flows. The update addresses eight specific cash flow issues, with the treatment of contingent consideration payments made after a business combination being the most directly applicable to the Company. The update requires that cash payments made approximately three months or less after an acquisition's consummation date should be classified as cash outflows for investing activities. Payment made thereafter up to the amount of the original contingent consideration liability should be classified as cash outflows from financing activities. Payments made in excess of the amount of the original contingent consideration liability should be classified as cash outflows from operating activities. The standard is effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. The standard will be applicable to the Company for the fiscal year beginning July 1, 2018. Early adoption is permitted, provided all eight amendments are adopted in the same period. The guidance requires adoption using a retrospective transition method. The Company is currently evaluating the impact on its consolidated financial statements upon the adoption of this new guidance. 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.
