ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES [Abstract]
BASIS OF PRESENTATION	BASIS OF PRESENTATION — Our company was founded in 1990 and is a Delaware corporation. ePlus inc. is sometimes referred to in this Quarterly Report on Form 10-Q as “we,” “our,” “us,” “ourselves,” or “ePlus.” The unaudited condensed consolidated financial statements include the accounts of ePlus inc. and its wholly-owned subsidiaries. All intercompany balances and transactions have been eliminated.
SUBSEQUENT EVENTS	SUBSEQUENT EVENTS — Management has evaluated subsequent events after the balance sheet date through the date our financial statements are issued.
USE OF ESTIMATES	USE OF ESTIMATES — The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at 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 intangibles, reserves 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.
REVENUE RECOGNITION	REVENUE RECOGNITION–The majority of our revenues are derived from the following sources: sales of products, sales of third-party software, sales of services provided by us, sales of third-party maintenance and services, financing revenues and sales of our software. For all these revenue sources, we determine whether we are the principal or agent in accordance with Accounting Standards Codification (“Codification”) Topic, Revenue Recognition, Subtopic Principal Agent Considerations. Our revenue recognition policies vary based upon these revenue sources. For the sale of third party software assurance, maintenance and services we concluded that we are acting as an agent and recognize revenue for these transactions on a net basis at the date of sale, which is presented within sales of products and services in our unaudited condensed consolidated statements of operations. Gross billings for all products and services for the three months ended June 30, 2013 and June 30, 2012 were $303.2 million and $278.7 million, respectively.
SHIPPING AND HANDLING	SHIPPING AND HANDLING – We record freight billed to our customers as sales of product and services, and the related expense as cost of sales, product and services.
EARNINGS PER SHARE	EARNINGS PER SHARE—Basic earnings per share is calculated by dividing net earnings attributable to common shareholders by the basic weighted average number of shares of common stock outstanding during each period. Diluted earnings per share reflects the potential dilution of securities that could participate in our earnings, including incremental shares issuable upon the assumed exercise of “in-the-money” stock options and other common stock equivalents during each period.
CONCENTRATIONS OF RISK
RECENTLY ADOPTED ACCOUNTING PRONOUNCEMENTS	RECENTLY ADOPTED ACCOUNTING PRONOUNCEMENTS —There were no new accounting standards issued during the three months ended June 30, 2013 that materially impacted our condensed consolidated financial statements or could materially impact our financial statements or related disclosures in a future period.

The disclosure may encompass important judgment as to appropriateness of principles related to recognition of revenue. The disclosure also may indicate the entity's treatment of any unearned or deferred revenue that arises from the transaction.
