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.
INTERIM FINANCIAL STATEMENTS	INTERIM FINANCIAL STATEMENTS — The condensed consolidated financial statements for the three and six months ended September 30, 2013 and 2012 are unaudited, but 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 equity and cash flows for such periods. Operating results for the three and six months ended September 30, 2013 and 2012 are not necessarily indicative of results that may be expected for any other interim period or for the full fiscal year ending March 31, 2014 or any other future period. These unaudited condensed consolidated financial statements do not include all disclosures required by the accounting principles generally accepted in the United States (“U.S. 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, 2013 (“2013 Annual Report”), which should be read in conjunction with these interim financial statements.
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.
ACCOUNTS RECEIVABLE - TRADE	ACCOUNTS RECEIVABLE—TRADE — Trade accounts receivable are recorded at the invoiced amount and typically do not bear interest. The Company provides allowances for doubtful accounts related to accounts receivable for estimated losses resulting from the inability of its customers to make required payments. Our reserve for credit losses was $1.0 million as of September 30, 2013 and March 31, 2013.
ACCOUNTS RECEIVABLE - OTHER	ACCOUNTS RECEIVABLE—OTHER — Accounts receivable—other consists of advances and payments made on behalf of our customers, as well as amounts due from vendors. Prior to the effective date of a lease or financing arrangement with our customer, any payments made by our financing segment for products and services for our customers are presented in accounts receivable—other as we generally act as an agent of our customer until the financing arrangement is accepted by our customer. We also receive incentives from vendors, including consideration pursuant to volume sales incentive programs, volume purchase incentive programs and shared marketing expense programs. These incentives generally relate to vendor programs with specified performance requirements, and estimated amounts earned but not paid by the vendors are included in accounts receivable—other. Our reserve for credit losses was $0.1 million as of September 30, 2013 and March 31, 2013.
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 September 30, 2013 and September 30, 2012 were $321.2 million and $318.8 million, respectively. Gross billings for all products and services for the six months ended September 30, 2013 and September 30, 2012 were $624.4 million and $597.6 million, respectively.
DEFERRED COSTS AND DEFERRED REVENUE	DEFERRED COSTS AND DEFERRED REVENUE – Deferred costs include internal and third party costs associated with deferred revenue arrangements. Deferred revenue relate to professional services, which are generally recognized upon completion, and maintenance, managed service or hosting arrangements that are recognized on a straight-line basis over the term of the arrangement.
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. We use the two-class method to allocate net income between common shares and other participating securities. For additional information, see Note 8, “Earnings Per Share”.
CONCENTRATIONS OF RISK	CONCENTRATIONS OF RISK — Financial instruments that potentially subject us to concentrations of credit risk include cash and cash equivalents, short-term investments, accounts receivable, notes receivable and investments in direct financing and sales-type leases. Cash and cash equivalents and short-term investments are maintained principally with financial institutions in the United States, which have high credit ratings. Risk associated with our accounts receivable, notes receivable and investments in direct financing and sales-type leases is reduced by the large number of diverse industries comprising our customer base and through the ongoing evaluation of collectability of our portfolio. Our credit risk is further mitigated through the underlying collateral and whether the lease is funded with recourse or non-recourse notes payable. A substantial portion of our sales of product and services are from sales of Cisco, Hewlett Packard, and NetApp products, which represented 46.8%, 11.2%, and 5.5%, and 50.5%, 10.4%, and 7.4%, respectively, of our sales of product and services for the three and six months ended September 30, 2013, as compared to 49.8%, 10.0%, and 7.2%, and 51.6%, 10.1%, and 6.7%, respectively, of our sales of product and services for the three and six months ended September 30, 2012. Any changes in our vendors’ ability to provide products could have a material adverse effect on our business, results of operations and financial condition.
RECENTLY ADOPTED ACCOUNTING PRONOUNCEMENTS	RECENTLY ADOPTED ACCOUNTING PRONOUNCEMENTS — There were no new accounting standards issued during the three months ended September 30, 2013 that materially impacted our condensed consolidated financial statements or could materially impact our financial statements or related disclosures in a future period.
