		The Company and Summary of Significant Accounting Policies and Estimates
	Business
	Guidewire Software, Inc., a Delaware corporation, was incorporated on September 20, 2001. Guidewire Software, Inc., together with its subsidiaries (the “Company”), provides Internet-based software platforms for core insurance operations, including underwriting and policy administration, claim management and billing. The Company’s customers include insurance carriers for property and casualty and workers’ compensation insurance. The Company has wholly-owned subsidiaries in Australia, Canada, China, France, Germany, Hong Kong, Ireland, Italy, Japan, Poland and the United Kingdom.
	The Company offers a suite of applications to enable core property and casualty (“P&C”) insurance operations comprised of the following products: PolicyCenter, ClaimCenter and BillingCenter. The Company also provides maintenance support and professional services to the extent requested by its customers.
	Public Offerings
	On October 28, 2013, the Company closed its follow-on public offering of 8,306,291 shares of its common stock, including the underwriters’ partial exercise of their over-allotment option from the Company. The public offering price of the shares sold in the offering was $48.75 per share. The Company received aggregate proceeds of approximately $389.9 million from the follow-on offering, net of underwriters’ discounts and commissions applicable to the sale of shares by the Company, but before deduction of offering costs of approximately $0.4 million payable by the Company. No shares were sold by the Company’s stockholders in this follow-on public offering.
	Basis of Presentation
	The accompanying unaudited condensed consolidated financial statements and accompanying notes include the Company and its wholly-owned subsidiaries, and reflect all adjustments (all of which are normal and recurring in nature) that, in the opinion of management, are necessary for a fair presentation of the interim periods presented. All inter-company balances and transactions have been eliminated in consolidation. Certain information and note disclosures normally included in annual financial statements prepared in accordance with generally accepted accounting principles in the United States of America (“U.S. GAAP”) have been condensed or omitted under the rules and regulations of the Securities and Exchange Commission (“SEC”).
	These unaudited interim condensed consolidated financial statements should be read in conjunction with the Company’s financial statements and related notes, together with management’s discussion and analysis of financial condition and results of operations, presented in the Company’s Annual Report on Form 10-K for the fiscal year ended July 31, 2014. There have been no changes in the Company’s significant accounting policies from those that were disclosed in the Company’s consolidated financial statements for the fiscal year ended July 31, 2014 included in the Company’s Annual Report on Form 10-K.
	Use of Estimates
	The preparation of the accompanying condensed consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions about future events that affect the amounts of assets and liabilities reported, disclosures about contingent assets and liabilities, and reported amounts of revenues and expenses. Significant items subject to such estimates include revenue recognition, the useful lives of property and equipment and intangible assets, allowance for doubtful accounts, valuation allowance for deferred tax assets, stock-based compensation, annual bonus attainment, income tax uncertainties, valuation of goodwill and intangible assets, and contingencies. These estimates and assumptions are based on management’s best estimates and judgment. Management regularly evaluates its estimates and assumptions using historical experience and other factors; however, actual results could differ significantly from these estimates.
	Cash, Cash Equivalents and Investments
	Cash and cash equivalents are comprised of cash and highly liquid investments with remaining maturities of 90 days or less at the date of purchase. Cash equivalents consist of commercial paper and money market funds. The Company classifies investments as short-term when they have remaining contractual maturities of less than one year from the balance sheet date, and as long-term when the investments have remaining contractual maturities of more than one year from the balance sheet date. The Company’s investment policy is consistent with the definition of available-for-sale securities. From time to time, the Company may sell certain securities but the objectives are generally not to generate profits on short-term differences in price.
	Concentration of Credit Risk
	Financial instruments that potentially subject the Company to concentrations of credit risk consist of cash, cash equivalents, investments and accounts receivable. The Company maintains its cash and cash equivalents with high quality financial institutions. The Company is exposed to credit risk for cash held in financial institutions in the event of a default to the extent that such amounts recorded on the balance sheet are in excess of amounts that are insured by the Federal Deposit Insurance Corporation (“FDIC”).
	No customer accounted for 10% or more of the Company’s revenues for the three months ended October 31, 2014 or 2013. One customer accounted for 10% or more of the Company’s total accounts receivable as of October 31, 2014 and July 31, 2014.
	Revenue Recognition
	The Company enters into arrangements to deliver multiple products or services (multiple-elements). The Company applies software revenue recognition rules and allocates the total revenues among elements based on vendor-specific objective evidence (“VSOE”) of fair value of each element. The Company recognizes revenue on a net basis excluding taxes collected from customers and remitted to government authorities.
	Revenues are derived from three sources:
	(i)	License fees, related to term (or time-based) licenses, perpetual software licenses, and other;
	(ii)	Maintenance fees, related to email and phone support, bug fixes and unspecified software updates and upgrades released when, and if, available during the maintenance term; and
	(iii)	Services fees, related to professional services related to implementation of our software, reimbursable travel and training.
	Revenues are recognized when all of the following criteria are met:
	•	Persuasive evidence of an arrangement exists. Evidence of an arrangement consists of a written contract signed by both the customer and management prior to the end of the period.
	•	Delivery or performance has occurred. The Company’s software is delivered electronically to the customer. Delivery is considered to have occurred when the Company provides the customer access to the software along with login credentials.
	•	Fees are fixed or determinable. Arrangements where a significant portion of the fee is due beyond 90 days from delivery are not considered to be fixed or determinable. Revenues from such arrangements are recognized as payments become due, assuming all other revenue recognition criteria have been met. Fees from term licenses are generally due in annual or, in certain cases, quarterly, installments over the term of the agreement beginning on the effective date of the license. Accordingly, fees from term licenses are not considered to be fixed or determinable until they become due.
	•	Collectability is probable. Collectability is assessed on a customer-by-customer basis, based primarily on creditworthiness as determined by credit checks and analysis, as well as customer payment history. Payment terms generally range from 30 to 90 days from invoice date. If it is determined prior to revenue recognition that collection of an arrangement fee is not probable, revenues are deferred until collection becomes probable or cash is collected, assuming all other revenue recognition criteria are satisfied.
	VSOE of fair value does not exist for the Company’s software licenses; therefore, the Company allocates revenues to software licenses using the residual method. Under the residual method, the amount recognized for license fees is the difference between the total fixed and determinable fees and the VSOE of fair value for the undelivered elements under the arrangement.
	The VSOE of fair value for elements of an arrangement is based upon the normal pricing and discounting practices for those elements when sold separately. VSOE of fair value for maintenance is established using the stated maintenance renewal rate in the customer’s contract. The Company generally enters into term licenses ranging from 3 to 7 years. For term licenses with duration of one year or less, no VSOE of fair value for maintenance exists. VSOE of fair value for services is established if a substantial majority of historical stand-alone selling prices for a service fall within a reasonably narrow price range.
	If the undelivered elements are all service elements and VSOE of fair value does not exist for one or more service element, the total arrangement fee is recognized ratably over the longest service period starting at software delivery, assuming all the related services have been made available to the customer.
	In certain offerings sold as fixed fee arrangements, the Company recognizes services revenues on a proportional performance basis as performance obligations are completed by using the ratio of labor hours to date as an input measure compared to total estimated labor hours for the consulting services.
	In cases where professional services are deemed to be essential to the functionality of the software, the arrangement is accounted for using contract accounting until the essential services are complete. If reliable estimates of total project costs can be made, the Company applies the percentage-of-completion method whereby percentage toward completion is measured by using the ratio of service billings to date compared to total estimated service billings for the consulting services. Service billings approximate labor hours as an input measure since they are generally billed monthly on a time and material basis. The fees related to the maintenance are recognized over the period the maintenance is provided.
	If reliable estimates of total project costs cannot be made or VSOE for maintenance has not been established and it is reasonably assured that no loss will be incurred under the arrangement, revenues are recognized pursuant to the zero gross margin method. Under this method, revenues recognized are limited to the costs incurred for the implementation services. When the zero gross margin method is applied for lack of reliable project estimates and subsequently project estimates become reliable, the Company switches to the percentage-of-completion method; resulting in a cumulative effect adjustment for deferred license revenues to the extent of progress toward completion, and the related deferred professional service margin is recognized in full as revenues. There were no such cumulative effect adjustments for revenues for the three months ended October 31, 2014 and 2013.
	Deferred Revenues
	Deferred revenues represent license, maintenance and professional services amounts, which are billed to or collected from customers for which the related revenues have not been recognized. The revenues are deferred when one or more of the revenue recognition criteria have not been met. The current portion of deferred revenues represents the amount that is expected to be recognized as revenues within one year from the balance sheet date. The Company generally invoices fees for licenses and maintenance to its customers in annual or, in certain cases, quarterly installments payable in advance. Accordingly, the deferred revenues balance does not represent the total contract value of annual or multi-year, non-cancellable arrangements.
	Income Taxes
	Income taxes are accounted for under the asset and liability method. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases and operating loss and tax credit carryforwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. Deferred tax assets related to excess tax benefits are recorded when utilized. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. The Company records a valuation allowance to reduce deferred tax assets to an amount of which realization is more likely than not.
	Accounting guidance related to accounting for uncertainties in income taxes provides that a tax benefit from an uncertain tax position may be recognized when it is more likely than not that the position will be sustained upon examination, including resolutions of any related appeals or litigation processes, based on the technical merits of the position. This interpretation also provides guidance on measurement, derecognition, classification, interest and penalties, accounting in interim periods, disclosure and transition.
	The Company records interest and penalties related to unrecognized tax benefits as income tax expense in its condensed consolidated statement of operations.
	Stock-Based Compensation
	The Company recognizes compensation expense related to its stock options and restricted stock units (“RSUs”) granted to employees based on the estimated fair value of the awards on the date of grant, net of estimated forfeitures. The RSUs are subject to time-based vesting, which generally occurs over a period of 4 years. The awards expire 10 years from the grant date. The Company estimates the grant date fair value, and the resulting stock-based compensation expense, of the Company’s stock options using the Black-Scholes option-pricing model. The Company determines the grant date fair value of its RSUs based on the closing market price of the Company’s common stock on the date of grant. The Company recognizes the fair value of stock-based compensation for awards which contain only service conditions on a straight-line basis over the requisite service period, which is generally the vesting period of the respective awards. The Company recognizes the compensation cost for awards which contain performance conditions based upon the probability of that performance condition being met, net of estimated forfeitures, using the graded method.
	In the fourth quarter of fiscal 2014, the Company changed its policy for recognizing stock-based compensation expense from the accelerated attribution method of accounting to the straight-line method of accounting for certain share-based compensation awards. Comparative financial statements for prior periods have been adjusted to apply the straight-line method retrospectively. See Note 2 “Change in Accounting Policy - Stock-based Compensation” of Notes to Consolidated Financial Statements for the fiscal year ended July 31, 2014 included in the Company’s Annual Report on Form 10-K filed with the SEC on September 17, 2014.
	Recent Accounting Pronouncement
	Stock-Based Compensation
	In June 2014, the FASB issued ASU No. 2014-12, Accounting for Share-Based Payments When the Terms of an Award Provide That a Performance Target Could Be Achieved after the Requisite Service Period (Topic 718). This ASU provides authoritative guidance for share-based payments with a performance condition that could be achieved after the requisite service period is achieved. The standard will be effective for the Company beginning August 1, 2016. The Company currently does not have such share-based arrangements and does not expect the adoption of this standard will have material impact on its condensed consolidated financial statements.
	Revenue from Contracts with Customers
	In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers (Topic 606) which provides guidance for revenue recognition. This ASU affects any entity that either enters into contracts with customers to transfer goods or services or enters into contracts for the transfer of non-financial assets. This ASU will supersede the revenue recognition requirements in Topic 605, Revenue Recognition, and most industry-specific guidance. This ASU also supersedes some cost guidance included in Subtopic 605-35, Revenue Recognition-Construction-Type and Production-Type Contracts. The standard will be effective for the Company beginning August 1, 2017. The Company is currently evaluating the impact of the adoption of this accounting standard update on its condensed consolidated financial statements.

	As of October 31, 2014, the Company had 89 investments in an unrealized loss position. The unrealized losses on its available-for-sale securities were primarily a result of unfavorable changes in interest rates subsequent to the initial purchase of these securities. The Company does not intend to sell, nor believe it will need to sell, these securities before recovering the associated unrealized losses. The Company does not consider any portion of the unrealized losses at October 31, 2014 to be an other-than-temporary impairment, nor are any unrealized losses considered to be credit losses. The Company has recorded the securities at fair value in its condensed consolidated balance sheets, with unrealized gains and losses reported as a component of accumulated other comprehensive loss. The amounts of realized gains and losses reclassified into earnings are based on the specific identification of the securities sold. The realized gains and losses from sales of securities in the periods presented were immaterial.
	The following table summarizes the contractual maturities of the Company’s available-for-sale securities as of October 31, 2014:

	Fair value is defined as the exchange price that would be received for an asset or an exit price 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. Valuation techniques used to measure fair value must maximize the use of observable inputs and minimize the use of unobservable inputs. The current accounting guidance for fair value measurements defines a three-level valuation hierarchy for disclosures as follows:
	Level 1—Unadjusted quoted prices in active markets for identical assets or liabilities;
	Level 2—Inputs other than quoted prices included within Level I that are observable, unadjusted quoted prices in markets that are not active, or other inputs that are observable or can be corroborated by observable market data; and
	Level 3—Unobservable inputs that are supported by little or no market activity, which require the Company to develop its own assumptions.
	The categorization of a financial instrument within the valuation hierarchy is based upon the lowest level of input that is significant to the fair value measurement. The carrying value of the Company’s accounts receivable, accounts payable and accrued liabilities approximates their fair value due to the short-term nature of these instruments.
	The Company bases the fair value of its Level 1 financial instruments, which are in active markets, using quoted market prices for identical instruments.
	The Company obtains the fair value of its Level 2 financial instruments, which are not in active markets, from a third-party professional pricing service using quoted market prices for identical or comparable instruments, rather than direct observations of quoted prices in active markets. The Company’s professional pricing service gathers observable inputs for all of its fixed income securities from a variety of industry data providers (e.g. large custodial institutions) and other third-party sources. Once the observable inputs are gathered, all data points are considered and an average price is determined.
	The Company validates the quoted market prices provided by its primary pricing service by comparing their assessment of the fair values of its Level 2 investment portfolio balance against the fair values of its Level 2 investment portfolio balance provided by its investment managers. Its investment managers use similar techniques to its professional pricing service to derive pricing as described above.
The Company did not have any Level 3 financial assets or liabilities as of October 31, 2014 or July 31, 2014.
The following tables summarize the Company’s financial assets measured at fair value on a recurring basis, by level within the fair value hierarchy as of October 31, 2014 and July 31, 2014:

	Commitments and Contingencies
	There has been no material change in the Company’s contractual obligations and commitments other than in the ordinary course of business since the Company’s fiscal year ended July 31, 2014. See the Annual Report on Form 10-K for the fiscal year ended July 31, 2014 for additional information regarding the Company’s contractual obligations.
	Leases
	The Company leases certain facilities and equipment under operating leases. On December 5, 2011, the Company entered into a seven-year lease for a facility to serve as its corporate headquarters, located in Foster City, California, for approximately 97,674 square feet of space which commenced on August 1, 2012. In connection with this lease, the Company opened an unsecured letter of credit with Silicon Valley Bank for $1.2 million. On August 1, 2014, the Company amended its operating lease agreement to reduce the unsecured letter of credit to $0.8 million.
	Lease expense for all worldwide facilities and equipment, which is being recognized on a straight-line basis over terms of the various leases, was $1.6 million and $1.4 million for the three months ended October 31, 2014 and 2013, respectively.
	Letters of Credit
	The Company had two outstanding letters of credit required to secure contractual commitments and prepayments as of October 31, 2014 and July 31, 2014, respectively. In addition to the unsecured letter of credit for the building lease, the Company had an unsecured letter of credit agreement related to a customer arrangement for Polish Zloty 10.0 million (approximately $3.0 million as of October 31, 2014) to secure contractual commitments and prepayments. No amounts were outstanding under the Company’s unsecured letters of credit as of October 31, 2014 or July 31, 2014.
	Legal Proceedings
	From time to time, the Company is involved in various legal proceedings and receives claims, arising from the normal course of business activities. The Company accrues for estimated losses in the accompanying condensed consolidated financial statements for matters with respect to which the Company believes the likelihood of an adverse outcome is probable and the amount of the loss is reasonably estimable.
	Indemnification
	The Company sells software licenses and services to its customers under contracts (“Software License”). Each Software License contains the terms of the contractual arrangement with the customer and generally includes certain provisions for defending the customer against any claims that the Company’s software infringes upon a patent, copyright, trademark, or other proprietary right of a third party. Software Licenses also indemnify the customer against losses, expenses, and liabilities from damages that may be assessed against the customer in the event the Company’s software is found to infringe upon such third party rights.
	The Company has not had to reimburse any of its customers for losses related to indemnification provisions and no material claims against the Company are outstanding as of October 31, 2014 and July 31, 2014. For several reasons, including the lack of prior indemnification claims and the lack of a monetary liability limit for certain infringement cases under various Software Licenses, the Company cannot estimate the amount of potential future payments, if any, related to indemnification provisions.
	The Company has also agreed to indemnify its directors and executive officers for costs associated with any fees, expenses, judgments, fines and settlement amounts incurred by any of these persons in any action or proceeding to which any of these persons is, or is threatened to be, made a party by reason of the person’s service as a director or officer, including any action by the Company, arising out of that person’s services as the Company’s director or officer or that person’s services provided to any other company or enterprise at the Company’s request. The Company maintains director and officer insurance coverage that may enable the Company to recover a portion of any future amounts paid.

Income Taxes	'
	Income Taxes
	The benefits from income taxes for the three months ended October 31, 2014 and 2013 were $0.6 million and $5.9 million, respectively. The change is primarily due to a smaller loss before income taxes in the current period, as compared to the same period a year ago. The effective tax rate of 17.0% for the three months ended October 31, 2014 differs from the statutory U.S. federal income tax rate of 35% mainly due to the benefit from incentive stock options tax deduction, permanent differences for stock-based compensation, the impact of state income taxes, the tax rate differences between the United States and foreign countries, and tax credits.
	The Company provides U.S. income taxes on the earnings of foreign subsidiaries, unless the subsidiaries’ earnings are considered indefinitely reinvested outside the United States. As of October 31, 2014, U.S. income taxes were not provided for on the cumulative total of $23.6 million undistributed earnings from certain foreign subsidiaries. As of October 31, 2014, the unrecognized deferred tax liability for these earnings was approximately $3.0 million.
	During the three months ended October 31, 2014, the change in unrecognized tax benefits from the beginning of the period was $0.2 million. Accordingly, as of October 31, 2014, the Company had unrecognized tax benefits of $4.3 million that, if recognized, would affect the Company’s effective tax rate.

Organization, Consolidation and Presentation of Financial Statements [Abstract]	'
Business	'
	Business
	Guidewire Software, Inc., a Delaware corporation, was incorporated on September 20, 2001. Guidewire Software, Inc., together with its subsidiaries (the “Company”), provides Internet-based software platforms for core insurance operations, including underwriting and policy administration, claim management and billing. The Company’s customers include insurance carriers for property and casualty and workers’ compensation insurance. The Company has wholly-owned subsidiaries in Australia, Canada, China, France, Germany, Hong Kong, Ireland, Italy, Japan, Poland and the United Kingdom.
	The Company offers a suite of applications to enable core property and casualty (“P&C”) insurance operations comprised of the following products: PolicyCenter, ClaimCenter and BillingCenter. The Company also provides maintenance support and professional services to the extent requested by its customers.
Basis of Presentation	'
	Basis of Presentation
	The accompanying unaudited condensed consolidated financial statements and accompanying notes include the Company and its wholly-owned subsidiaries, and reflect all adjustments (all of which are normal and recurring in nature) that, in the opinion of management, are necessary for a fair presentation of the interim periods presented. All inter-company balances and transactions have been eliminated in consolidation. Certain information and note disclosures normally included in annual financial statements prepared in accordance with generally accepted accounting principles in the United States of America (“U.S. GAAP”) have been condensed or omitted under the rules and regulations of the Securities and Exchange Commission (“SEC”).
	These unaudited interim condensed consolidated financial statements should be read in conjunction with the Company’s financial statements and related notes, together with management’s discussion and analysis of financial condition and results of operations, presented in the Company’s Annual Report on Form 10-K for the fiscal year ended July 31, 2014. There have been no changes in the Company’s significant accounting policies from those that were disclosed in the Company’s consolidated financial statements for the fiscal year ended July 31, 2014 included in the Company’s Annual Report on Form 10-K.
Use of Estimates	'
	Use of Estimates
	The preparation of the accompanying condensed consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions about future events that affect the amounts of assets and liabilities reported, disclosures about contingent assets and liabilities, and reported amounts of revenues and expenses. Significant items subject to such estimates include revenue recognition, the useful lives of property and equipment and intangible assets, allowance for doubtful accounts, valuation allowance for deferred tax assets, stock-based compensation, annual bonus attainment, income tax uncertainties, valuation of goodwill and intangible assets, and contingencies. These estimates and assumptions are based on management’s best estimates and judgment. Management regularly evaluates its estimates and assumptions using historical experience and other factors; however, actual results could differ significantly from these estimates.
Cash. Cash Equivalents, Investments and Restricted Cash	'
	Cash, Cash Equivalents and Investments
	Cash and cash equivalents are comprised of cash and highly liquid investments with remaining maturities of 90 days or less at the date of purchase. Cash equivalents consist of commercial paper and money market funds. The Company classifies investments as short-term when they have remaining contractual maturities of less than one year from the balance sheet date, and as long-term when the investments have remaining contractual maturities of more than one year from the balance sheet date. The Company’s investment policy is consistent with the definition of available-for-sale securities. From time to time, the Company may sell certain securities but the objectives are generally not to generate profits on short-term differences in price.
Concentration of Credit Risk	'
	Concentration of Credit Risk
	Financial instruments that potentially subject the Company to concentrations of credit risk consist of cash, cash equivalents, investments and accounts receivable. The Company maintains its cash and cash equivalents with high quality financial institutions. The Company is exposed to credit risk for cash held in financial institutions in the event of a default to the extent that such amounts recorded on the balance sheet are in excess of amounts that are insured by the Federal Deposit Insurance Corporation (“FDIC”).
	No customer accounted for 10% or more of the Company’s revenues for the three months ended October 31, 2014 or 2013. One customer accounted for 10% or more of the Company’s total accounts receivable as of October 31, 2014 and July 31, 2014.
Revenue Recognition	'
	Revenue Recognition
	The Company enters into arrangements to deliver multiple products or services (multiple-elements). The Company applies software revenue recognition rules and allocates the total revenues among elements based on vendor-specific objective evidence (“VSOE”) of fair value of each element. The Company recognizes revenue on a net basis excluding taxes collected from customers and remitted to government authorities.
	Revenues are derived from three sources:
	(i)	License fees, related to term (or time-based) licenses, perpetual software licenses, and other;
	(ii)	Maintenance fees, related to email and phone support, bug fixes and unspecified software updates and upgrades released when, and if, available during the maintenance term; and
	(iii)	Services fees, related to professional services related to implementation of our software, reimbursable travel and training.
	Revenues are recognized when all of the following criteria are met:
	•	Persuasive evidence of an arrangement exists. Evidence of an arrangement consists of a written contract signed by both the customer and management prior to the end of the period.
	•	Delivery or performance has occurred. The Company’s software is delivered electronically to the customer. Delivery is considered to have occurred when the Company provides the customer access to the software along with login credentials.
	•	Fees are fixed or determinable. Arrangements where a significant portion of the fee is due beyond 90 days from delivery are not considered to be fixed or determinable. Revenues from such arrangements are recognized as payments become due, assuming all other revenue recognition criteria have been met. Fees from term licenses are generally due in annual or, in certain cases, quarterly, installments over the term of the agreement beginning on the effective date of the license. Accordingly, fees from term licenses are not considered to be fixed or determinable until they become due.
	•	Collectability is probable. Collectability is assessed on a customer-by-customer basis, based primarily on creditworthiness as determined by credit checks and analysis, as well as customer payment history. Payment terms generally range from 30 to 90 days from invoice date. If it is determined prior to revenue recognition that collection of an arrangement fee is not probable, revenues are deferred until collection becomes probable or cash is collected, assuming all other revenue recognition criteria are satisfied.
	VSOE of fair value does not exist for the Company’s software licenses; therefore, the Company allocates revenues to software licenses using the residual method. Under the residual method, the amount recognized for license fees is the difference between the total fixed and determinable fees and the VSOE of fair value for the undelivered elements under the arrangement.
	The VSOE of fair value for elements of an arrangement is based upon the normal pricing and discounting practices for those elements when sold separately. VSOE of fair value for maintenance is established using the stated maintenance renewal rate in the customer’s contract. The Company generally enters into term licenses ranging from 3 to 7 years. For term licenses with duration of one year or less, no VSOE of fair value for maintenance exists. VSOE of fair value for services is established if a substantial majority of historical stand-alone selling prices for a service fall within a reasonably narrow price range.
	If the undelivered elements are all service elements and VSOE of fair value does not exist for one or more service element, the total arrangement fee is recognized ratably over the longest service period starting at software delivery, assuming all the related services have been made available to the customer.
	In certain offerings sold as fixed fee arrangements, the Company recognizes services revenues on a proportional performance basis as performance obligations are completed by using the ratio of labor hours to date as an input measure compared to total estimated labor hours for the consulting services.
	In cases where professional services are deemed to be essential to the functionality of the software, the arrangement is accounted for using contract accounting until the essential services are complete. If reliable estimates of total project costs can be made, the Company applies the percentage-of-completion method whereby percentage toward completion is measured by using the ratio of service billings to date compared to total estimated service billings for the consulting services. Service billings approximate labor hours as an input measure since they are generally billed monthly on a time and material basis. The fees related to the maintenance are recognized over the period the maintenance is provided.
	If reliable estimates of total project costs cannot be made or VSOE for maintenance has not been established and it is reasonably assured that no loss will be incurred under the arrangement, revenues are recognized pursuant to the zero gross margin method. Under this method, revenues recognized are limited to the costs incurred for the implementation services. When the zero gross margin method is applied for lack of reliable project estimates and subsequently project estimates become reliable, the Company switches to the percentage-of-completion method; resulting in a cumulative effect adjustment for deferred license revenues to the extent of progress toward completion, and the related deferred professional service margin is recognized in full as revenues. There were no such cumulative effect adjustments for revenues for the three months ended October 31, 2014 and 2013.
Deferred Revenues	'
	Deferred Revenues
	Deferred revenues represent license, maintenance and professional services amounts, which are billed to or collected from customers for which the related revenues have not been recognized. The revenues are deferred when one or more of the revenue recognition criteria have not been met. The current portion of deferred revenues represents the amount that is expected to be recognized as revenues within one year from the balance sheet date. The Company generally invoices fees for licenses and maintenance to its customers in annual or, in certain cases, quarterly installments payable in advance. Accordingly, the deferred revenues balance does not represent the total contract value of annual or multi-year, non-cancellable arrangements.
Income Taxes	'
	Income Taxes
	Income taxes are accounted for under the asset and liability method. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases and operating loss and tax credit carryforwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. Deferred tax assets related to excess tax benefits are recorded when utilized. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. The Company records a valuation allowance to reduce deferred tax assets to an amount of which realization is more likely than not.
	Accounting guidance related to accounting for uncertainties in income taxes provides that a tax benefit from an uncertain tax position may be recognized when it is more likely than not that the position will be sustained upon examination, including resolutions of any related appeals or litigation processes, based on the technical merits of the position. This interpretation also provides guidance on measurement, derecognition, classification, interest and penalties, accounting in interim periods, disclosure and transition.
	The Company records interest and penalties related to unrecognized tax benefits as income tax expense in its condensed consolidated statement of operations.
Stock-Based Compensation	'
	Stock-Based Compensation
	The Company recognizes compensation expense related to its stock options and restricted stock units (“RSUs”) granted to employees based on the estimated fair value of the awards on the date of grant, net of estimated forfeitures. The RSUs are subject to time-based vesting, which generally occurs over a period of 4 years. The awards expire 10 years from the grant date. The Company estimates the grant date fair value, and the resulting stock-based compensation expense, of the Company’s stock options using the Black-Scholes option-pricing model. The Company determines the grant date fair value of its RSUs based on the closing market price of the Company’s common stock on the date of grant. The Company recognizes the fair value of stock-based compensation for awards which contain only service conditions on a straight-line basis over the requisite service period, which is generally the vesting period of the respective awards. The Company recognizes the compensation cost for awards which contain performance conditions based upon the probability of that performance condition being met, net of estimated forfeitures, using the graded method.
	In the fourth quarter of fiscal 2014, the Company changed its policy for recognizing stock-based compensation expense from the accelerated attribution method of accounting to the straight-line method of accounting for certain share-based compensation awards. Comparative financial statements for prior periods have been adjusted to apply the straight-line method retrospectively. See Note 2 “Change in Accounting Policy - Stock-based Compensation” of Notes to Consolidated Financial Statements for the fiscal year ended July 31, 2014 included in the Company’s Annual Report on Form 10-K filed with the SEC on September 17, 2014.
Recent Accounting Pronouncement	'
	Recent Accounting Pronouncement
	Stock-Based Compensation
	In June 2014, the FASB issued ASU No. 2014-12, Accounting for Share-Based Payments When the Terms of an Award Provide That a Performance Target Could Be Achieved after the Requisite Service Period (Topic 718). This ASU provides authoritative guidance for share-based payments with a performance condition that could be achieved after the requisite service period is achieved. The standard will be effective for the Company beginning August 1, 2016. The Company currently does not have such share-based arrangements and does not expect the adoption of this standard will have material impact on its condensed consolidated financial statements.
	Revenue from Contracts with Customers
	In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers (Topic 606) which provides guidance for revenue recognition. This ASU affects any entity that either enters into contracts with customers to transfer goods or services or enters into contracts for the transfer of non-financial assets. This ASU will supersede the revenue recognition requirements in Topic 605, Revenue Recognition, and most industry-specific guidance. This ASU also supersedes some cost guidance included in Subtopic 605-35, Revenue Recognition-Construction-Type and Production-Type Contracts. The standard will be effective for the Company beginning August 1, 2017. The Company is currently evaluating the impact of the adoption of this accounting standard update on its condensed consolidated financial statements.
