| Commitments and Contingencies Disclosure [Text Block]   | Commitments and ContingenciesAgilysys is the subject of various threatened or pending legal actions and contingencies in the normal course of conducting its business. We provide for costs related to these matters when a loss is probable and the amount can be reasonably estimated. The effect of the outcome of these matters on our future results of operations and liquidity cannot be predicted because any such effect depends on future results of operations and the amount or timing of the resolution of such matters. While it is not possible to predict with certainty, management believes that the ultimate resolution of such individual or aggregated matters will not have a material adverse effect on our consolidated financial position, results of operations, or cash flows.On April 6, 2012, Ameranth, Inc. filed a complaint against us for patent infringement in the United States District Court for the Southern District of California. The complaint alleges, among other things, that point-of-sale and property management and other hospitality information technology products, software, components and/or systems sold by us infringe three patents owned by Ameranth purporting to cover generation and synchronization of menus, including restaurant menus, event tickets, and other products across fixed, wireless and/or internet platforms as well as synchronization of hospitality information and hospitality software applications across fixed, wireless and internet platforms. The complaint seeks monetary damages, injunctive relief, costs and attorneys' fees. At this time, we are not able to predict the outcome of this lawsuit, or any possible monetary exposure associated with the lawsuit.  However, we dispute the allegations of wrongdoing and are vigorously defending ourselves in this matter. |
