Accounting Policies [Abstract]
Use of Estimates, Policy [Policy Text Block]	Use of Estimates We make estimates and assumptions that affect the amounts reported in the financial statements and the disclosures made in the accompanying notes. For example, we use estimates in determining the appropriate levels of reserves for product returns and rebates, the collectibility of accounts receivable, the appropriate levels of various accruals, the amount of our worldwide tax provision and the realizability of deferred tax assets. We also use estimates in determining the remaining economic lives and carrying values of acquired intangible assets, property and equipment, and other long-lived assets. In addition, we use assumptions to estimate the fair value of reporting units, share-based compensation and illiquid municipal auction rate securities. Despite our intention to establish accurate estimates and use reasonable assumptions, actual results may differ from our estimates.
Revenue Recognition Policy [Policy Text Block]	Revenue Recognition We derive revenue from the sale of packaged software products, software subscriptions, hosted services, technical support plans, financial supplies, implementation services, transaction fees, merchant services hardware, and multiple element arrangements that may include a combination of these items. We recognize revenue when all four revenue recognition criteria have been met: persuasive evidence of an arrangement exists, we have delivered the product or performed the service, the fee is fixed or determinable, and collectibility is probable. Determining whether and when these criteria have been satisfied involves exercising judgment and using estimates and assumptions that can have a significant impact on the timing and amount of revenue that we recognize. In some situations, we receive advance payments from our customers. We defer revenue associated with these advance payments and the relative fair value of undelivered elements under multiple element arrangements until we ship the products or perform the services. We account for cash consideration (such as sales incentives) that we give to our customers or resellers as a reduction of revenue rather than as an operating expense unless we receive a benefit that we can identify and for which we can reasonably estimate the fair value. Product Revenue We recognize revenue from the sale of our packaged software products, financial supplies such as printed check stock, and merchant services hardware such as retail point-of-sale equipment and credit card readers for mobile phones, when legal title transfers. This is generally when our customers download products from the Web, when we ship the products or, in the case of certain agreements, when products are delivered to retailers. We sell some of our QuickBooks, TurboTax and Quicken desktop software products on consignment to certain retailers. We recognize revenue for these consignment transactions only when the end-user sale has occurred. For software products that are sold on a subscription basis and include periodic updates, we recognize revenue ratably over the term of the contract. We record product revenue net of our sales tax obligations. We reduce product revenue from distributors and retailers for estimated returns that are based on historical returns experience and other factors, such as the volume and price mix of products in the retail channel, return rates for prior releases of the product, trends in retailer inventory and economic trends that might impact customer demand for our products (including the competitive environment and the timing of new releases of our product). We also reduce product revenue for the estimated redemption of rebates on certain current product sales. Our estimated reserves for distributor and retailer sales incentive rebates are based on distributors’ and retailers’ actual performance against the terms and conditions of rebate programs. Our reserves for end user rebates are estimated based on the terms and conditions of the specific promotional rebate program, actual sales during the promotion and historical redemption trends by product and by type of promotional program. Service and Other Revenue Our service revenue consists primarily of hosted services such as QuickBooks Online and TurboTax Online, payroll services, electronic merchant payment processing services, electronic tax filing services, and outsourced online banking services for financial institutions. Our service revenue also includes QuickBooks technical support plans in our Financial Management Solutions segment and implementation fees in our Financial Services segment and our Intuit Health business. We recognize revenue from hosted services as the services are performed, provided we have no other remaining obligations to these customers. We generally require customers to remit payroll tax funds to us in advance of the payroll date via electronic funds transfer. We include in total net revenue the interest that we earn on these funds between the time that we collect them from customers and the time that we remit them to outside parties. Service revenue for electronic payment processing services that we provide to merchants is recorded net of interchange fees charged by credit card associations. We offer several QuickBooks technical support plans and recognize support revenue over the life of the plans. We recognize revenue for upfront fees for implementation services in our Financial Services segment and our Intuit Health business ratably over the greater of the initial life of the customer contract or the estimated life of the customer service relationship. Other revenue consists primarily of revenue from revenue-sharing and royalty arrangements with third-party partners. We typically recognize this revenue as earned based upon reporting provided to us by our partners. Multiple Element Arrangements We enter into multiple element revenue arrangements in which a customer may purchase a combination of software, upgrades, hosted services, technical support, and hardware. Our multiple element arrangements are predominantly software and software-related. Multiple Element Arrangements That Contain Software and Software-Related Elements For multiple element arrangements that contain only software and software-related elements, such as QuickBooks desktop software and paid technical support plans, we allocate and defer revenue for the undelivered elements based on their vendor-specific objective evidence of fair value (VSOE). VSOE is the price charged when that element is sold separately. In situations where VSOE exists for all elements (delivered and undelivered), we allocate the total revenue to be earned under the arrangement among the various elements, based on their relative fair value. For arrangements where VSOE exists only for the undelivered elements, we defer the full fair value of the undelivered elements and recognize the difference between the total arrangement fee and the amount deferred for the undelivered items as revenue. If VSOE does not exist for an undelivered service element, we recognize the revenue from the entire arrangement as the services are delivered. If VSOE does not exist for undelivered elements that are specified products or features, we defer revenue until the earlier of the delivery of all elements or the point at which we determine VSOE for these undelivered elements. We recognize revenue related to the delivered products or services only if: (1) the above revenue recognition criteria are met; (2) any undelivered products or services are not essential to the functionality of the delivered products and services; (3) payment for the delivered products or services is not contingent upon delivery of the remaining products or services; and (4) we have an enforceable claim to receive the amount due in the event that we do not deliver the undelivered products or services. Multiple Element Arrangements That Contain Non-Software Elements For multiple element arrangements that contain non-software elements such as hosted services or credit card readers for mobile phones, we: (1) determine whether and when each element has been delivered; (2) determine the fair value of each element using the selling price hierarchy of vendor-specific evidence of fair value (VSOE) of fair value if available, third-party evidence (TPE) if VSOE is not available, and estimated selling price (ESP) if neither VSOE nor TPE is available; and (3) allocate the total price among the various elements using the relative selling price method. Once we have allocated the total price among the various elements, we recognize revenue when the revenue recognition criteria described above are met for each element. VSOE generally exists when we sell the deliverable separately and we are normally able to establish VSOE for all deliverables in these multiple element arrangements; however, in certain limited instances VSOE cannot be established. This may be because we infrequently sell each element separately, do not price products or services within a narrow range, or have a limited sales history. When VSOE cannot be established, we attempt to establish selling price for each element based on TPE. TPE is determined based on competitor prices for similar deliverables when sold separately. When we are unable to establish selling price using VSOE or TPE, we use ESP in our allocation of arrangement consideration. ESP is the estimated price at which we would sell a product or service if it were sold on a stand-alone basis. We determine ESP for a product or service by considering multiple factors including, but not limited to, pricing practices, market conditions, competitive landscape, type of customer, geographies, stage of product lifecycle, internal costs, and gross margin objectives. Significant pricing practices that we take into consideration include historic contractually stated prices, volume discounts where applicable, and our price lists. The determination of ESP is made through consultation with and formal approval by management, taking into consideration our overall go-to-market strategy.
Shipping and Handling Cost, Policy [Policy Text Block]	Shipping and Handling We record the amounts we charge our customers for the shipping and handling of our software products as product revenue and we record the related costs as cost of product revenue in our statements of operations.
Selling, General and Administrative Expenses, Policy [Policy Text Block]	Customer Service and Technical Support We include the costs of providing customer service under paid technical support contracts on the cost of service and other revenue line in our statements of operations. We include customer service and free technical support costs in selling and marketing expense in our statements of operations. Customer service and technical support costs include costs associated with performing order processing, answering customer inquiries by telephone and through websites, e-mail and other electronic means, and providing free technical support assistance to customers. In connection with the sale of certain products, we provide a limited amount of free technical support assistance to customers. We do not defer the recognition of any revenue associated with sales of these products, since the cost of providing this free technical support is insignificant. The technical support is generally provided within one year after the associated revenue is recognized and free product enhancements are minimal and infrequent. We accrue the estimated cost of providing this free support upon product shipment.
Research, Development, and Computer Software, Policy [Policy Text Block]	Software Development Costs We expense software development costs as we incur them until technological feasibility has been established, at which time those costs are capitalized until the product is available for general release to customers. To date, our software has been available for general release concurrent with the establishment of technological feasibility and, accordingly, we have not capitalized any development costs. Costs we incur to enhance our existing products or after the general release of the service using the product are expensed in the period they are incurred and included in research and development expense in our statements of operations.
Internal Use Software, Policy [Policy Text Block]	Internal Use Software We capitalize costs related to computer software obtained or developed for internal use. Software obtained for internal use has generally been enterprise-level business and finance software that we customize to meet our specific operational needs. Software developed for internal use has generally been used to deliver hosted services to our customers. Costs incurred in the application development phase are capitalized and amortized over their useful lives, which are generally three to five years.
Advertising Costs, Policy [Policy Text Block]	Advertising We expense all advertising costs as we incur them to selling and marketing expense in our statements of operations.
Lease, Policy [Policy Text Block]	Leases We review all leases for capital or operating classification at their inception. We use our incremental borrowing rate in the assessment of lease classification and define the initial lease term to include the construction build-out period but to exclude lease extension periods. We conduct our operations primarily under operating leases. For leases that contain rent escalations, we record the total rent payable during the lease term, as defined above, on a straight-line basis over the term of the lease. We record the difference between the rent paid and the straight-line rent in a deferred rent account in other current liabilities or other long-term obligations, as appropriate, on our balance sheets. We record landlord allowances as deferred rent liabilities in other current liabilities or other long-term obligations, as appropriate, on our balance sheets. We record landlord cash incentives as operating activity on our statements of cash flows. We record other landlord allowances as non-cash investing and financing activities on our statements of cash flows. We classify the amortization of landlord allowances as a reduction of occupancy expense in our statements of operations.
Interest Expense, Policy [Policy Text Block]	Capitalization of Interest Expense We capitalize interest on capital projects, including facilities build-out projects and internal use computer software projects. Capitalization commences with the first expenditure for the project and continues until the project is substantially complete and ready for its intended use. We amortize capitalized interest to depreciation expense using the straight-line method over the same lives as the related assets. Capitalized interest was not significant for any period presented.
Foreign Currency Transactions and Translations Policy [Policy Text Block]	Foreign Currency The functional currencies of our international operating subsidiaries are generally the local currencies. We translate the assets and liabilities of our foreign subsidiaries at the exchange rates in effect on the balance sheet date. We translate their revenue, costs and expenses at the average rates of exchange in effect during the period. We include translation gains and losses in the stockholders’ equity section of our balance sheets. We include net gains and losses resulting from foreign exchange transactions in interest and other income in our statements of operations. Translation gains and losses and transaction gains and losses were not significant for any period presented.
Income Tax, Policy [Policy Text Block]	Income Taxes We estimate our income taxes based on the various jurisdictions where we conduct business. Significant judgment is required in determining our worldwide income tax provision. We estimate our current tax liability and assess temporary differences that result from differing treatments of certain items for tax and accounting purposes. These differences result in deferred tax assets and liabilities, which we show on our balance sheet. We must then assess the likelihood that our deferred tax assets will be realized. To the extent we believe that realization is not likely, we establish a valuation allowance. When we establish a valuation allowance or increase this allowance in an accounting period, we record a corresponding income tax expense in our statement of operations. We review the need for a valuation allowance to reflect uncertainties about whether we will be able to utilize some of our deferred tax assets before they expire. The valuation allowance analysis is based on our estimates of taxable income for the jurisdictions in which we operate and the periods over which our deferred tax assets will be realizable. While we have considered future taxable income in assessing the need for a valuation allowance for the periods presented, we could be required to record a valuation allowance to take into account additional deferred tax assets that we may be unable to realize. An increase in the valuation allowance would have an adverse impact, which could be material, on our income tax provision and net income in the period in which we record the increase. We recognize and measure benefits for uncertain tax positions using a two-step approach. The first step is to evaluate the tax position taken or expected to be taken in a tax return by determining if the weight of available evidence indicates that it is more likely than not that the tax position will be sustained upon audit, including resolution of any related appeals or litigation processes. For tax positions that are more likely than not of being sustained upon audit, the second step is to measure the tax benefit as the largest amount that is more than 50% likely of being realized upon settlement. Significant judgment is required to evaluate uncertain tax positions. We evaluate our uncertain tax positions on a quarterly basis. Our evaluations are based upon a number of factors, including changes in facts or circumstances, changes in tax law, correspondence with tax authorities during the course of audits and effective settlement of audit issues. Changes in the recognition or measurement of uncertain tax positions could result in material increases or decreases in our income tax expense in the period in which we make the change, which could have a material impact on our effective tax rate and operating results. A description of our accounting policies associated with tax-related contingencies and valuation allowances assumed as part of a business combination is provided under “Business Combinations” below.
Computation of Net Income Per Share [Policy Text Block]	Computation of Net Income Per Share We compute basic net income or loss per share using the weighted average number of common shares outstanding during the period. We compute diluted net income per share using the weighted average number of common shares and dilutive potential common shares outstanding during the period. Dilutive potential common shares consist of the shares issuable upon the exercise of stock options and upon the vesting of restricted stock units (RSUs) under the treasury stock method. We include stock options with combined exercise prices, unrecognized compensation expense and tax benefits that are less than the average market price for our common stock, and RSUs with combined unrecognized compensation expense and tax benefits that are less than the average market price for our common stock, in the calculation of diluted net income per share. We exclude stock options with combined exercise prices, unrecognized compensation expense and tax benefits that are greater than the average market price for our common stock, and RSUs with combined unrecognized compensation expense and tax benefits that are greater than the average market price for our common stock, from the calculation of diluted net income per share because their effect is anti-dilutive. Under the treasury stock method, the amount that must be paid to exercise stock options, the amount of compensation expense for future service that we have not yet recognized for stock options and RSUs, and the amount of tax benefits that will be recorded in additional paid-in capital when the awards become deductible are assumed to be used to repurchase shares. Beginning in July 2012, all of the RSUs we grant have dividend rights. Since the dividend rights are subject to the same vesting requirements as the underlying equity awards they are considered a contingent transfer of value. Consequently, the RSUs are not considered participating securities and we do not present them separately in earnings per share.
Cash Equivalents And Investments Policy [Policy Text Block]	Cash Equivalents and Investments We consider highly liquid investments with maturities of three months or less at the date of purchase to be cash equivalents. Cash equivalents consist primarily of AAA-rated money market funds in all periods presented. Investments consist of available-for-sale investment-grade debt securities that we carry at fair value. Long-term investments consist of municipal auction rate securities and an available-for-sale corporate equity investment that we carry at fair value. Due to a decrease in liquidity in the global credit markets, we estimate the fair values of the municipal auction rate securities based on a discounted cash flow model that we prepare. See Note 2 for more information. Except for direct obligations of the United States government, securities issued by agencies of the United States government, and money market funds, we diversify our investments by limiting our holdings with any individual issuer. We use the specific identification method to compute gains and losses on investments. We include unrealized gains and losses on investments, net of tax, in accumulated other comprehensive income in the stockholders’ equity section of our balance sheets. We generally classify available-for-sale debt securities as current assets based upon our ability and intent to use any and all of these securities as necessary to satisfy the significant short-term liquidity requirements that may arise from the highly seasonal nature of our businesses. Because of our significant business seasonality, stock repurchase programs, and acquisition opportunities, cash flow requirements may fluctuate dramatically from quarter to quarter and require us to use a significant amount of the investments we hold as available-for-sale securities.
Receivables, Policy [Policy Text Block]	Accounts Receivable and Allowances for Doubtful Accounts Accounts receivable are recorded at the invoiced amount and are not interest bearing. We maintain an allowance for doubtful accounts to reserve for potentially uncollectible receivables. We review our accounts receivable by aging category to identify significant customers or invoices with known disputes or collectibility issues. For those invoices not specifically identified as uncollectible, we provide an allowance based on the age of the receivable. In determining the amount of the allowance, we make judgments about the creditworthiness of significant customers based on ongoing credit evaluations. We also consider our historical level of credit losses and current economic trends that might impact the level of future credit losses. When we determine that amounts are uncollectible we write them off against the allowance.
Funds Held For Customers And Customer Fund Deposits Policy [Policy Text Block]	Funds Held for Customers and Customer Fund Deposits Funds held for customers represent cash held on behalf of our customers that is invested in cash and cash equivalents and investment grade available-for-sale debt securities. Customer fund deposits consist of amounts we owe on behalf of our customers, such as direct deposit payroll funds and payroll taxes.
Property, Plant and Equipment, Policy [Policy Text Block]	Property and Equipment Property and equipment is stated at cost, net of accumulated depreciation. We calculate depreciation using the straight-line method over the estimated useful lives of the assets, which range from two to 30 years. We amortize leasehold improvements using the straight-line method over the lesser of their estimated useful lives or remaining lease terms. We include the amortization of assets that are recorded under capital leases in depreciation expense.
Business Combinations and Other Purchase of Business Transactions, Policy [Policy Text Block]	Business Combinations The acquisition method of accounting for business combinations requires us to use significant estimates and assumptions, including fair value estimates, as of the business combination date and to refine those estimates as necessary during the measurement period (defined as the period, not to exceed one year, in which we may adjust the provisional amounts recognized for a business combination) in a manner that is generally similar to the previous purchase method of accounting. Under the acquisition method of accounting we recognize separately from goodwill the identifiable assets acquired, the liabilities assumed, and any noncontrolling interests in an acquiree, generally at the acquisition date fair value. We measure goodwill as of the acquisition date as the excess of consideration transferred, which we also measure at fair value, over the net of the acquisition date amounts of the identifiable assets acquired and liabilities assumed. Costs that we incur to complete the business combination such as investment banking, legal and other professional fees are not considered part of consideration and we charge them to general and administrative expense as they are incurred. Under the acquisition method we also account for acquired company restructuring activities that we initiate separately from the business combination. Should the initial accounting for a business combination be incomplete by the end of a reporting period that falls within the measurement period, we report provisional amounts in our financial statements. During the measurement period, we adjust the provisional amounts recognized at the acquisition date to reflect new information obtained about facts and circumstances that existed as of the acquisition date that, if known, would have affected the measurement of the amounts recognized as of that date and we record those adjustments to our financial statements. We apply those measurement period adjustments that we determine to be significant retrospectively to comparative information in our financial statements, including adjustments to depreciation and amortization expense. Under the acquisition method of accounting for business combinations, if we identify changes to acquired deferred tax asset valuation allowances or liabilities related to uncertain tax positions during the measurement period and they relate to new information obtained about facts and circumstances that existed as of the acquisition date, those changes are considered a measurement period adjustment and we record the offset to goodwill. We record all other changes to deferred tax asset valuation allowances and liabilities related to uncertain tax positions in current period income tax expense. This accounting applies to all of our acquisitions regardless of acquisition date.
Goodwill and Intangible Assets, Policy [Policy Text Block]	Goodwill, Acquired Intangible Assets and Other Long-Lived Assets Goodwill We record goodwill when the fair value of consideration transferred in a business combination exceeds the fair value of the identifiable assets acquired and liabilities assumed. Goodwill and other intangible assets that have indefinite useful lives are not amortized, but we test them for impairment annually during our fourth fiscal quarter and whenever an event or change in circumstances indicates that the carrying value of the asset may not be recoverable. For goodwill, we perform a two-step impairment test. In the first step, we compare the fair value of each reporting unit to its carrying value. In accordance with authoritative guidance, we define fair value as the price that would be received from the sale of an asset or paid to transfer a liability in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. We consider and use all valuation methods that are appropriate in estimating the fair value of our reporting units and generally use a weighted combination of income and market approaches. Under the income approach, we estimate the fair value of each reporting unit based on the present value of future cash flows. We use a number of assumptions in our discounted cash flow model, including market factors specific to the business, the amount and timing of estimated future cash flows to be generated by the business over an extended period of time, long-term growth rates for the business, and a rate of return that considers the relative risk of achieving the cash flows and the time value of money. Under the market approach, we estimate the fair value of each reporting unit based on market multiples of revenue, operating income, and earnings for comparable publicly traded companies engaged in similar businesses. If the estimated fair value of the reporting unit exceeds the carrying value of the net assets assigned to that unit, goodwill is not impaired and no further analysis is required. If the carrying value of the net assets assigned to a reporting unit exceeds the estimated fair value of the unit, we perform the second step of the impairment test. In this step we allocate the fair value of the reporting unit calculated in step one to all of the assets and liabilities of that unit, as if we had just acquired the reporting unit in a business combination. The excess of the fair value of the reporting unit over the total amount allocated to the assets and liabilities represents the implied fair value of goodwill. If the carrying value of a reporting unit’s goodwill exceeds its implied fair value, we would record an impairment loss equal to the difference. See Note 2, "Fair Value Measurements - Assets and Liabilities Measured at Fair Value on a Non-Recurring Basis," for a discussion of the goodwill impairment charge that we recorded for the twelve months ended July 31, 2011. We recorded no goodwill impairment charges for the twelve months ended July 31, 2012 or 2010. Acquired Intangible Assets and Other Long-Lived Assets We generally record acquired intangible assets that have finite useful lives, such as acquired technology, in connection with business combinations. We amortize the cost of acquired intangible assets on a straight-line basis over their estimated useful lives, which range from one to nine years. We review intangible assets that have finite useful lives and other long-lived assets whenever an event or change in circumstances indicates that the carrying value of the asset may not be recoverable. We estimate the recoverability of these assets by comparing the carrying amount of the asset to the future undiscounted cash flows that we expect the asset to generate. We estimate the fair value of assets that have finite useful lives based on the present value of future cash flows for those assets. If the carrying value of an asset with a finite life exceeds its estimated fair value, we would record an impairment loss equal to the difference. See Note 2, "Fair Value Measurements - Assets and Liabilities Measured at Fair Value on a Non-Recurring Basis," for a discussion of the acquired intangible asset impairment charge that we recorded for the twelve months ended July 31, 2011. We recorded no impairment charges for acquired intangible assets for the twelve months ended July 31, 2012 or 2010.
Share Based Compensation Plans Policy [Policy Text Block]	Share-Based Compensation Plans We estimate the fair value of stock options granted using a lattice binomial model and a multiple option award approach. We use historical data to estimate pre-vesting option forfeitures and record share-based compensation expense only for those awards that are expected to vest. We amortize the fair value of stock options on a straight-line basis over the requisite service periods of the awards, which are generally the vesting periods. Restricted stock units (RSUs) granted typically vest based on continued service. We value these time-based RSUs at the date of grant using the intrinsic value method, adjusted for estimated forfeitures. We amortize the fair value of time-based RSUs on a straight-line basis adjusted for estimated forfeitures over the service period. Certain RSUs granted to senior management vest based on the achievement of pre-established performance or market goals. We estimate the fair value of performance-based RSUs at the date of grant using the intrinsic value method and the probability that the specified performance criteria would be met, adjusted for estimated forfeitures. Each quarter we update our assessment of the probability that the specified performance criteria will be achieved and adjust our estimate of the fair value of the performance-based RSUs if necessary. We amortize the fair values of performance-based RSUs over the requisite service period adjusted for estimated forfeitures for each separately vesting tranche of the award. We estimate the fair value of market-based RSUs at the date of grant using a Monte Carlo valuation methodology and amortize those fair values over the requisite service period adjusted for estimated forfeitures for each separately vesting tranche of the award. The Monte Carlo methodology that we use to estimate the fair value of market-based RSUs at the date of grant incorporates into the valuation the possibility that the market condition may not be satisfied. Provided that the requisite service is rendered, the total fair value of the market-based RSUs at the date of grant must be recognized as compensation expense even if the market condition is not achieved. However, the number of shares that ultimately vest can vary significantly with the performance of the specified market criteria. Beginning in July 2012 all of the RSUs we grant have dividend rights that are subject to the same vesting requirements as the underlying equity awards, so we do not adjust the intrinsic (market) value of our RSUs for dividends. See Note 12, "Stockholders' Equity," for a description of our share-based compensation plans and more information on the assumptions we use to calculate the fair value of share-based compensation.
Concentration Of Credit Risk And Significant Customers And Suppliers Policy [Policy Text Block]	Concentration of Credit Risk and Significant Customers and Suppliers We operate in markets that are highly competitive and rapidly changing. Significant technological changes, shifting customer needs, the emergence of competitive products or services with new capabilities and other factors could negatively impact our operating results. We are also subject to risks related to changes in the value of our significant balance of investments. Our portfolio of investments consists of investment-grade securities. Except for direct obligations of the United States government, securities issued by agencies of the United States government and money market funds, we diversify our investments by limiting our holdings with any individual issuer. We sell a significant portion of our products through third-party retailers and distributors. As a result, we face risks related to the collectibility of our accounts receivable. To appropriately manage this risk, we perform ongoing evaluations of customer credit and limit the amount of credit extended as we deem appropriate, but generally do not require collateral. We maintain reserves for estimated credit losses and these losses have historically been within our expectations. However, since we cannot predict future changes in the financial stability of our customers, we cannot guarantee that our reserves will continue to be adequate. No customer accounted for 10% or more of total net revenue for the twelve months ended July 31, 2012, 2011 or 2010, nor did any customer account for 10% or more of total accounts receivable at July 31, 2012 or 2011. We rely primarily on one third-party vendor to perform the manufacturing and distribution functions for our retail desktop software products. We also have a key single-source vendor that prints and fulfills orders for most of our financial supplies business. While we believe that relying on key vendors improves the efficiency and reliability of our business operations, relying on any one vendor for a significant aspect of our business can have a significant negative impact on our revenue and profitability if that vendor fails to perform at acceptable service levels for any reason, including financial difficulties of the vendor.
