Accounting Policies [Abstract]
BASIS OF PRESENTATION	BASIS OF PRESENTATION — The unaudited consolidated financial statements include the accounts of ePlus inc. and its wholly-owned subsidiaries. All intercompany balances and transactions have been eliminated in consolidation. The accounts of businesses acquired are included in the unaudited consolidated financial statements from the dates of acquisition.
INTERIM FINANCIAL STATEMENTS	INTERIM FINANCIAL STATEMENTS — The unaudited consolidated financial statements for the three and nine months ended December 31, 2024, and 2023, were prepared by us and include all normal and recurring adjustments that, in the opinion of management, are necessary for a fair presentation of our financial position, results of operations, changes in comprehensive income, and cash flows for such periods. Operating results for the three and nine months ended December 31, 2024, and 2023, are not necessarily indicative of results that may be expected for any other interim period or for the full fiscal year ended March 31, 2025, or any other future period. These unaudited consolidated financial statements do not include all disclosures required by the accounting principles generally accepted in the United States (“US GAAP”) for annual financial statements. Our audited consolidated financial statements are contained in our annual report on Form 10-K for the year ended March 31, 2024 (“2024 Annual Report”), which should be read in conjunction with these interim consolidated financial statements.
USE OF ESTIMATES	USE OF ESTIMATES — The preparation of financial statements in conformity with US GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities as of the date of the financial statements, and the reported amounts of revenues and expenses during the reporting periods. Estimates are used when accounting for items and matters including, but not limited to, revenue recognition, residual values, vendor consideration, lease classification, goodwill and intangible assets, allowance for credit losses, inventory obsolescence, and the recognition and measurement of income tax assets and other provisions and contingencies. We base our estimates on historical experience and on various other assumptions that we believe to be reasonable under the circumstances. Actual results may differ from these estimates.
CONCENTRATIONS OF RISK	CONCENTRATIONS OF RISK — A substantial portion of our sales are products from Cisco Systems, which represented approximately 27% and 36% of our technology business net sales for the three months ended December 31, 2024, and 2023, respectively, and 34% and 45% of our technology business net sales for the nine months ended December 31, 2024, and 2023, respectively.
