Accounting Policies [Abstract]
Basis of Accounting	The accompanying condensed consolidated financial statements have been prepared by the Company in accordance with accounting principles generally accepted in the United States of America ("U.S. GAAP") for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all the information and footnotes required by generally accepted accounting principles for complete financial statements. In the opinion of management, all adjustments (consisting of a normal recurring nature) considered necessary for fair presentation have been included. These unaudited condensed consolidated financial statements should be read in conjunction with the audited financial statements and related notes for the year ended July 31, 2020 (Fiscal Year 2020), which are contained in the Company's Annual Report on Form 10-K filed with the Securities and Exchange Commission on September 30, 2020. The results for the six months ended January 31, 2021 are not necessarily indicative of the results to be expected for the full fiscal year. The year-end condensed consolidated balance sheet data was derived from audited consolidated financial statements, but does not include all disclosures required by U.S. GAAP.
Consolidation	All significant intercompany transactions and balances have been eliminated in consolidation.

The amendments in ASU 2018-13 were effective in the first quarter of the Company's fiscal year ending July 31, 2021 (Fiscal Year 2021). The adoption of the accounting standard did not have a material impact on the Company's financial statements.

ASU 2018-14 modifies the disclosure requirements for employers that sponsor defined benefit pension and other post-retirement plans.

The adoption of the accounting standard did not have a material impact on the Company's financial statements. In August 2018, the FASB issued ASU 2018-15, Intangibles-Goodwill and Other-Internal-Use Software (Subtopic 350-40): Customer's Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract (a consensus of the FASB Emerging Issues Task Force) to align the requirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software (and hosting arrangements that include an internal use software license). The amendments in ASU 2018-15 became effective for the Company's first quarter of Fiscal Year 2021. The adoption of the accounting standard did not have a material impact on the Company's consolidated financial statements. Accounting Standards Issued and Not Yet Implemented In June 2016, the FASB issued ASU 2016-13, Financial Instruments-Credit Losses (Topic 326): Measurement of Credit Loses on Financial Instruments, an ASU that requires measurement and recognition of expected credit losses for financial instruments, including trade receivables, based on historical experience, current conditions, and reasonable and supportable forecasts that affect the collectability of the reported amount. The ASU will be effective for the Company beginning in the first quarter of the fiscal year ending July 31, 2024 on a modified retrospective basis, which requires a cumulative effect adjustment to retained earnings as of the beginning of the first reporting period in which the guidance is effective. The Company is currently evaluating this guidance to determine the impact it may have on its consolidated financial statements. In December 2019, the FASB issued ASU 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes, which amends the existing guidance relating to the accounting for income taxes. This ASU is intended to simplify the accounting for income taxes by removing certain exceptions to the general principles of accounting for income taxes and to improve the consistent application of U.S. GAAP for other areas of accounting for income taxes by clarifying and amending existing guidance. The new guidance is effective for the Company's first quarter of the fiscal year ending July 31, 2022. The Company does not expect that the adoption of this new guidance will have a material impact on its consolidated financial statements. In March 2020, the FASB issued ASU 2020-04, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting, which is intended to provide temporary optional expedients and exceptions for applying U.S. GAAP to contracts, hedging relationships and other transactions affected by the discontinuation of the London Interbank Offered Rate, known as LIBOR, or by another reference rate expected to be discontinued. This optional guidance is effective beginning on March 12, 2020, and the Company may elect to apply the amendments prospectively through December 31, 2022. The Company is currently evaluating this guidance to determine the impact it may have on its consolidated financial statements. In August 2020, the FASB issued ASU 2020-06, Debt-Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging-Contracts in Entity's Own Equity (Subtopic 815-40). The amendment in this update simplifies the accounting for convertible instruments by reducing the number of accounting models available for convertible debt instruments and convertible preferred stock. This update also amends the guidance for the derivatives scope exception for contracts in an entity's own equity to reduce form-over-substance-based accounting conclusions and requires the application of the if-converted method for calculating diluted earnings per share. The update also requires entities to provide expanded disclosures about the terms and features of convertible instruments, how the instruments have been reported in the entity's financial statements and information about events, conditions and circumstances that can affect how to assess the amount or timing of an entity's future cash flows related to those instruments. The guidance is effective for interim and annual periods beginning in our fiscal year ending July 31, 2025, with early adoption permitted. The Company is currently evaluating this guidance to determine the impact it may have on its consolidated financial statements.
Fair Value of Financial Instruments	ASC 820 provides that fair value is an exit price, representing the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants based on the highest and best use of the asset or liability. As such, fair value is a market-based measurement that should be determined based on assumptions that market participants would use in pricing an asset or liability. ASC 820 requires the Company to use valuation techniques to measure fair value that maximize the use of observable inputs and minimize the use of unobservable inputs. These inputs are prioritized as follows: Level 1: Observable inputs such as quoted prices for identical assets or liabilities in active markets Level 2: Other inputs that are observable directly or indirectly, such as quoted prices for similar assets or liabilities or market-corroborated inputs Level 3: Unobservable inputs for which there is little or no market data and which require the Company to develop its own assumptions about how market participants would price the assets or liabilities The carrying value of cash and cash equivalents, accounts receivable, restricted cash, accounts payable, current liabilities and the revolving line of credit approximate fair value because of the short maturity of these instruments. We believe that the carrying value of our long-term debt approximates fair value because the stated interest rates of this debt is consistent with current market rates. The carrying value of capital lease obligations approximates fair value, as estimated by using discounted future cash flows based on the Company's current incremental borrowing rates for similar types of borrowing arrangements.
