ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES [Abstract]
ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	1. ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES 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 — The condensed consolidated financial statements for the three and six months ended September 30, 2012 and 2011 are unaudited, but include all adjustments consisting of normal 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, 2012 and 2011 are not necessarily indicative of results that may be expected for any other interim period or for the full fiscal year ending March 31, 2013 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, 2012, which should be read in conjunction with these interim financial statements. SUBSEQUENT EVENTS — Management has evaluated subsequent events after the balance sheet date through the date our financial statements are issued. USE OF ESTIMATES — The preparation of financial statements in conformity with U.S. GAAP 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. Significant items subject to such estimates and assumptions include estimates related to revenue recognition, residual values, vendor consideration, lease classification, goodwill and intangibles, reserves for credit losses, and the recognition and measurement of income tax assets and liabilities. 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–The majority of our revenues are derived from the following sources: sales of third party products, software, software assurance, maintenance and services; sales of our services and software; and financing revenues. For all these revenue sources, we determine whether we are the principal or agent in accordance with Codification Topic, Revenue Recognition, Subtopic Principal Agent Considerations. Our revenue recognition policies vary based on 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, 2012 and September 30, 2011 were $318.8 million and $252.7 million, respectively. Gross billings for all products and services for the six months ended September 30, 2012 and September 30, 2011 were $597.6 million and $454.7 million, respectively. 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 on 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 asset is funded with recourse or non-recourse notes payable. A substantial portion of our sales of product and services are from sales of Cisco and Hewlett Packard products, which represented approximately 49.8% and 10.0%, and 51.6% and 10.1%, respectively, of our sales of product and services for the three and six months ended September 30, 2012, as compared to 46.1% and 17.2%, and 44.0% and 16.4%, respectively, of our sales of product and services for the three and six months ended September 30, 2011. 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 — In June 2011, the Financial Accounting Standard Board ("FASB") issued Accounting Standards Update ("ASU") 2011-12, Comprehensive Income ("ASU 2011-12"), which amended existing guidance by allowing only two options for presenting the components of net income and other comprehensive income: (1) in a single continuous financial statement, statement of comprehensive income or (2) in two separate but consecutive financial statements, consisting of an income statement followed by a separate statement of other comprehensive income. ASU 2011-12 requires retrospective application, and it is effective for fiscal years, and interim periods within those years, beginning after December 15, 2011, with early adoption permitted. We adopted this amendment on April 1, 2012 and are presenting our components of net income and other comprehensive income in two separate but consecutive financial statements.

1. ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

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."

INTERIM FINANCIAL STATEMENTS — The condensed consolidated financial statements for the three and six months ended September 30, 2012 and 2011 are unaudited, but include all adjustments consisting of normal 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.
