Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	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, 2012. See the Annual Report on Form 10-K for the fiscal year ended July 31, 2012 for additional information regarding our 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 a letter of credit with Silicon Valley Bank for $1.2 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 $1.4 million and $3.8 million during the three and nine months ended April 30, 2013, respectively, and $1.6 million and $3.5 million for the three and nine months ended April 30, 2012, respectively. This expense was reduced by sublease income of $0.3 million and $0.9 million for the three and nine months ended April 30, 2012, respectively. Letters of Credit In addition to the unsecured letter of credit noted above, the Company had an unsecured letter of credit agreement related to a customer arrangement for Polish Zloty 10.0 million (approximately $3.1 million as of April 30, 2013) to secure contractual commitments and prepayments. No amounts were outstanding under our unsecured letters of credit as of April 30, 2013 or July 31, 2012. The Company had no outstanding secured letters of credit as of April 30, 2013. As of July 31, 2012, the Company had three outstanding letters of credit required by certain customers to secure contractual commitments and prepayments. These letters of credit were fully secured by cash balances, which we classified as restricted cash in our consolidated balance sheets as of July 31, 2012. Legal Proceedings In December 2007, Accenture Global Services GmbH and Accenture LLP (collectively, “Accenture”) filed a lawsuit against the Company in the U.S. District Court for the District of Delaware, (the "Delaware Court") titled Accenture Global Services GmbH and Accenture LLP v. Guidewire Software, Inc., Case No 07-826-SLR. Accenture alleged infringement of U.S. Patent No. 7,013,284, ("the '284 patent"), among others, by the Company’s products; trade-secret misappropriation; and tortious interference with business relations. Accenture sought damages and an injunction. The Company denied Accenture’s claims, and it asserted counterclaims seeking a declaration that the Company's products do not infringe either patent, that the patents are invalid and that the '284 patent is unenforceable. The Company also asserted counterclaims against Accenture for breach of contract and trade secret misappropriation. In March 2011, the USPTO granted a third re-examination against the '284 patent, after having rejected all claims in the '284 patent on two prior re-examinations. On May 31, 2011, the Delaware Court granted the Company’s motion for summary judgment finding that Accenture’s '284 patent is invalid. In July 2011, Accenture filed an appeal to the Federal Circuit Court of Appeals (the "Appeals Court") of the Delaware Court’s judgment of invalidity of the '284 patent. We believe that the Delaware Court was correct in finding the '284 patent invalid and we intend to vigorously defend the Delaware Court's judgment in the appeal. On August 6, 2012, the oral argument of this appeal was held by the Appeals Court and their ruling is pending. However, at this time, the Company is unable to predict the likelihood of success of Accenture's appeal. In October 2011, the Company agreed with Accenture to resolve all outstanding patent litigation concerning their respective insurance claims management software. In connection with the settlement, the Company has paid $10.0 million to Accenture with a potential additional payment based on the final outcome of Accenture’s pending appeal regarding the validity of its ‘284 patent. If Accenture is successful in its appeal, the Company has agreed to pay them an additional $20.0 million. At any time prior to an initial determination by the appeals court, the Company may instead pay Accenture $15.0 million to discharge this potential obligation. If Accenture is not successful in its appeal, no further payments would be due in connection with the settlement. As part of the settlement, the Company also agreed to a royalty free cross license of all then-current patents and patent applications. The Company expensed the $10.0 million litigation provision in fiscal year 2011. In addition to the matters described above, from time to time, the Company is involved in various other legal proceedings and receives claims from time to time, arising from the normal course of business activities. The Company has accrued for estimated losses in the accompanying condensed consolidated financial statements for matters with respect to which we believe 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. The Software License also indemnifies 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 April 30, 2013 and July 31, 2012. For several reasons, including the lack of prior indemnification claims and the lack of a monetary liability limit for certain infringement cases under the Software License, 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.

Legal Proceedings

In December 2007, Accenture Global Services GmbH and Accenture LLP (collectively, “Accenture”) filed a lawsuit against the Company in the U.S. District Court for the District of Delaware, (the "Delaware Court") titled Accenture Global Services GmbH and Accenture LLP v. Guidewire Software, Inc., Case No 07-826-SLR. Accenture alleged infringement of U.S. Patent No. 7,013,284, ("the '284 patent"), among others, by the Company’s products; trade-secret misappropriation; and tortious interference with business relations. Accenture sought damages and an injunction. The Company denied Accenture’s claims, and it asserted counterclaims seeking a declaration that the Company's products do not infringe either patent, that the patents are invalid and that the '284 patent is unenforceable. The Company also asserted counterclaims against Accenture for breach of contract and trade secret misappropriation. In March 2011, the USPTO granted a third re-examination against the '284 patent, after having rejected all claims in the '284 patent on two prior re-examinations.

On May 31, 2011, the Delaware Court granted the Company’s motion for summary judgment finding that Accenture’s '284 patent is invalid. In July 2011, Accenture filed an appeal to the Federal Circuit Court of Appeals (the "Appeals Court") of the Delaware Court’s judgment of invalidity of the '284 patent. We believe that the Delaware Court was correct in finding the '284 patent invalid and we intend to vigorously defend the Delaware Court's judgment in the appeal. On August 6, 2012, the oral argument of this appeal was held by the Appeals Court and their ruling is pending. However, at this time, the Company is unable to predict the likelihood of success of Accenture's appeal.

In October 2011, the Company agreed with Accenture to resolve all outstanding patent litigation concerning their respective insurance claims management software. In connection with the settlement, the Company has paid $10.0 million to Accenture with a potential additional payment based on the final outcome of Accenture’s pending appeal regarding the validity of its ‘284 patent. If Accenture is successful in its appeal, the Company has agreed to pay them an additional $20.0 million. At any time prior to an initial determination by the appeals court, the Company may instead pay Accenture $15.0 million to discharge this potential obligation. If Accenture is not successful in its appeal, no further payments would be due in connection with the settlement. As part of the settlement, the Company also agreed to a royalty free cross license of all then-current patents and patent applications. The Company expensed the $10.0 million litigation provision in fiscal year 2011.

In addition to the matters described above, from time to time, the Company is involved in various other legal proceedings and receives claims from time to time, arising from the normal course of business activities. The Company has accrued for estimated losses in the accompanying condensed consolidated financial statements for matters with respect to which we believe 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. The Software License also indemnifies 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 April 30, 2013 and July 31, 2012. For several reasons, including the lack of prior indemnification claims and the lack of a monetary liability limit for certain infringement cases under the Software License, 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.
