Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The accompanying unaudited condensed consolidated financial statements include the accounts and our results of operations and our majority owned and controlled subsidiaries. All intercompany balances and transactions have been eliminated in the accompanying unaudited condensed consolidated financial statements. These unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States (“GAAP”) for interim financial information and the applicable rules and regulations of the Securities and Exchange Commission ("SEC"). Accordingly, they do not include all the information and footnotes required by GAAP for annual financial statements. They should be read together with our audited consolidated financial statements and related notes for the year ended December 31, 2014 appearing in our final prospectus for our IPO dated June 25, 2015 and filed with the SEC, pursuant to Rule 424(b) under the Securities Act of 1933, as amended on June 26, 2015. The condensed balance sheet data as of December 31, 2014 was derived from our audited financial statements, but does not include all disclosures required by GAAP. In the opinion of management, these condensed consolidated financial statements include all normal recurring adjustments necessary for a fair presentation of the results of operations, financial position and cash flows. The results of operations for the three and nine months ended September 30, 2015 are not necessarily indicative of the results that can be expected for the entire fiscal year ending December 31, 2015.
Use of Estimates	Use of Estimates The preparation of consolidated financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Our estimates, judgments and assumptions are continually evaluated based on available information and experience. Because of the use of estimates inherent in the financial reporting process, actual results could differ from those estimates. Estimates are used when accounting for revenue recognition, allowances for doubtful accounts receivable, allowance for hardware returns, estimates of obsolete inventory, long-term incentive compensation, stock-based compensation, income taxes, legal reserves, contingent consideration and goodwill and intangible assets.
Recent Accounting Pronouncements	Recent Accounting Pronouncements Adopted On April 10, 2014, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2014-08, “Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity,” which amends the definition of a discontinued operation in ASC 205-20 and requires entities to provide additional disclosures about discontinued operations as well as disposal transactions that do not meet the discontinued operations criteria. The guidance narrowed the definition of discontinued operations for disposal of a component or group of components that represents a strategic shift that has or will have a major impact on an entity’s operations or financial results. The guidance also expands the scope to include equity method investments and businesses that, upon initial acquisition, qualify as held for sale. The expanded disclosure requirements include statement of financial position and statement of cash flows disclosures for all comparative periods. The ASU 2014-08 is effective prospectively for all disposals (or classifications as held for sale) in periods beginning on or after December 15, 2014 with early adoption permitted. We adopted this pronouncement in the first quarter of 2015, and it did not have a material impact on our financial statements. On August 18, 2015, the FASB issued ASU 2015-15, “Interest- Imputation of Interest (Subtopic 835-30): Presentation and Subsequent Measurement of Debt Issuance Costs Associated with Line-of-Credit Arrangements - Amendments to SEC Paragraphs Pursuant to Staff Announcement at June 18, 2015, EITF Meeting,” which clarifies the application of ASU 2015-03 related to presentation and subsequent measurement of debt issuance costs related to line-of-credit arrangements to allow for an entity to defer and present debt issuance costs as an asset and subsequently amortize the deferred debt issuance costs ratably over the line-of-credit arrangement, regardless of whether there are any outstanding borrowings. ASU 2015-03, “Simplifying the Presentation of Debt Issuance Costs,” otherwise requires debt issuance costs to be presented in the balance sheet as a direct deduction from the carrying value of the associated debt liability, consistent with the presentation of a debt discount. We adopted these pronouncements in the third quarter of 2015. The adoption did not have an impact on our financial statements. We continue to present the debt issuance costs associated with our revolving credit facility as an asset that is amortized ratably over the term of the agreement. Not yet adopted On September 25, 2015, the FASB issued ASU 2015-16, “Business Combinations (Topic 805): Simplifying the Accounting for Measurement-Period Adjustments,” which requires entities to apply the guidance prospectively to adjustments to provisional amounts that occur after the effective date. Under current guidance, the acquirer retrospectively adjusts provisional amounts recognized as of the acquisition date with a corresponding adjustment to goodwill. Adjustments are required when new information is obtained about facts and circumstances that existed as of the acquisition date that, if known, would have affected the measurement of the amounts initially recognized or would have resulted in the recognition of additional assets or liabilities. The amendments in ASU 2015-16 eliminate the requirement to retrospectively account for those adjustments. The amendment is effective for annual periods, including periods within those annual periods beginning after December 15, 2015 with early adoption permitted. We are required to adopt this pronouncement prospectively in the first quarter of 2016, and we do not anticipate that adoption of the pronouncement will have a material impact on our financial statements. On August 12, 2015, the FASB issued ASU 2015-14, "Revenue from Contracts with Customers (Topic 606): Deferral of the Effective Date," which defers the effective date for all entities for one year of ASU 2014-09, “Revenue from Contracts with Customers (Topic 606),” issued on May 28, 2014. ASU 2014-09 affects any entity that either enters into contracts with customers to transfer goods or services or enters into contracts for the transfer of nonfinancial assets unless those contracts are within the scope of other standards. The guidance supersedes the revenue recognition guidance in Topic 605, “Revenue Recognition,” and most industry-specific guidance throughout the Industry Topics of the FASB Accounting Standards Codification. The guidance also supersedes some cost guidance included in Subtopic 605-35, “Revenue Recognition - Contract-Type and Production-Type Contracts." ASU 2014-9, as amended, is effective for annual periods, and interim periods within those years, beginning after December 31, 2017. An entity is required to apply the amendments using one of the following two methods: (1) retrospectively to each prior period presented with three possible expedients: (a) for completed contracts that begin and end in the same reporting period no restatement is required; (b) for completed contract with variable consideration an entity may use the transaction price at completion rather than restating estimated variable consideration amounts in comparable reporting periods; and (c) for comparable reporting periods before date of initial application reduced disclosure requirements related to transaction price; (2) retrospectively with the cumulative effect of initially applying the amendment recognized at the date of initial application with additional disclosures for the differences of the prior guidance to the reporting periods compared to the new guidance and an explanation of the reasons for significant changes. We are required to adopt ASU 2014-09 in the first quarter of 2018, and we are currently assessing the impact of this pronouncement on our financial statements. On July 22, 2015, the FASB issued ASU 2015-11, “Simplifying the Measurement of Inventory,” which requires entities to measure most inventory "at the lower of cost and net realizable value," thereby simplifying the current guidance under which an entity must measure inventory at the lower of cost or market (market in this context is defined as one of three different measures). The guidance does not apply to inventories that are measured by using either the last-in, first-out method or the retail inventory method. Under current guidance, an entity subsequently measures inventory at the lower of cost or market, with market defined as replacement cost provided that it is not above the ceiling (net realizable value) or below the floor (net realizable value less an approximately normal profit margin) which is unnecessarily complex. The amendment does not change other guidance on measuring inventory. The amendment is effective for annual periods, including periods within those annual periods beginning after December 15, 2016 with early adoption permitted. We are required to adopt this pronouncement prospectively in the first quarter of 2017, and we are currently assessing the impact of this pronouncement on our financial statements. On April 15, 2015, the FASB issued ASU 2015-05, “Intangibles - Goodwill and Other - Internal- Use Software (Subtopic 350-40): Customer’s Accounting for Fees Paid in a Cloud Computing Arrangement,” which clarifies the accounting for fees paid by a customer in a cloud computing arrangement by providing guidance as to whether an arrangement includes the sale or license of software. The amendment requires a customer to determine whether a cloud computing arrangement contains a software license. If the arrangement contains a software license, the customer would account for the fees related to the software license element in a manner consistent with how the acquisition of other software licenses is accounted for under ASC 350-40; if the arrangement does not contain a software license, the customer would account for the arrangement as a service contract. The guidance will not change GAAP for a customer’s accounting for service contracts. The amendment is effective for annual periods, including periods within those annual periods beginning after December 31, 2015 with early adoption permitted. We can elect to adopt the amendments either prospectively to all arrangements entered into or materially modified after the effective date or retrospectively. We are required to adopt this pronouncement in the first quarter of 2016, and we are currently assessing the impact of this pronouncement on our financial statements. On February 18, 2015, the FASB issued ASU 2015-02, “Consolidation (Topic 810): Amendments to the Consolidation Analysis,” which requires an entity to evaluate whether it should consolidate certain legal entities. All legal entities are subject to reevaluation under the revised consolidation model. The amendment modifies the evaluation of whether limited partnerships and similar legal entities are variable interest entities ("VIEs"). The amendment eliminates the presumption that a general partner should consolidate a limited partnership. The amendment affects the consolidation analysis of reporting entities that are involved with VIEs particularly those that have fee arrangements and related party relationships. The amendment also provides a scope exception from consolidation guidance for reporting entities that comply with the requirements for registered money market funds. We are required to adopt ASU 2015-02 in the first quarter of 2016, and we do not anticipate that adoption of the pronouncement will have a material effect on our financial statements. On August 27, 2014, the FASB issued ASU 2014-15, “Presentation of Financial Statements — Going Concern (Subtopic 205-40),” which requires management to perform interim and annual assessments regarding conditions or events that raise substantial doubt about a company’s ability to continue as a going concern and to provide related disclosures, if applicable. We are required to adopt ASU 2014-15 in the first quarter of 2017, with early adoption permitted. We do not anticipate that the adoption of this standard will have a material effect on our financial statements. On June 19, 2014, the FASB issued ASU 2014-12, “Compensation - Stock Compensation (Topic 718),” which affects any entity that grants its employees share-based payments in which the terms of the award stipulate that a performance target that affects vesting could be achieved after the requisite service period. The amendments require that a performance target that affects vesting and that could be achieved after the requisite service period be treated as a performance condition. As such, the performance target should not be reflected in estimating the grant-date fair value of the award. Compensation cost should be recognized in the period in which it becomes probable that the performance target will be achieved and should represent the compensation cost attributable to the period(s) for which the requisite service has already been rendered. If the performance target becomes probable of being achieved before the end of the requisite service period, the remaining unrecognized compensation cost should be recognized prospectively over the remaining requisite service period. We are required to adopt ASU 2014-12 in the first quarter of 2016 and the adoption of this standard is not expected to have a material effect on our financial statements.
