Exhibit 99.3

May 31, 2011

Dear Valued Customer:

Today Agilysys entered into a definitive agreement to sell our Technology Solutions Group (TSG) to OnX Enterprise Solutions, a leading IT solutions provider focused on designing and delivering mission-critical data center solutions. This transaction provides a great opportunity for TSG to accelerate its transformation into a multi-vendor, customer-focused solutions provider as part of a larger organization when combined with OnX.

With more than $700 million in combined revenues, we believe OnX and TSG will be an excellent combination with expanded market reach, broader solution offerings, and additional value for our customers. Based in Toronto, Canada, and with offices in the United States and Europe, OnX has more than 25 years of experience, time-tested technical and business acumen, and a unique vendor-neutral approach that ensures unbiased solution design.

In making this acquisition, OnX recognizes the tremendous market opportunity of the combined businesses, which reflects the talents, dedication and hard work of the employees who built TSG into what it is today.

Going forward, we expect the integration of TSG into OnX to be a seamless one for customers of both entities, providing the continued high level of service to which you have become accustomed. Please contact me if you have any questions.

Dear Valued Customer:

I want to introduce myself as the new interim president and CEO of Agilysys, and to share with you some important news that will allow Agilysys to devote all of its resources toward serving you better. As we announced today, Agilysys entered into a definitive agreement to sell its Technology Solutions Group (TSG) business to OnX Enterprise Solutions, a leading IT solutions provider focused on designing and delivering mission-critical data center solutions.

With this transaction, Agilysys will be able to pursue a singular focus on its growth prospects as a leading provider of proprietary software, services and solutions to the hospitality and retail industries. We will continue to specialize in market-leading point-of-sale, property management, inventory and procurement, and mobile and wireless solutions designed to streamline operations, improve efficiency and enhance the consumer’s experience. The Company will continue to operate extensively throughout North America, with additional sales and support offices in the United Kingdom, Singapore and Hong Kong.

As a more focused business with significant financial flexibility, we intend to accelerate growth in the hospitality and retail solutions business. This growth will be fueled by our distinctively new, industry-specific enterprise applications being deployed across our growing marquee customer base in the global hospitality markets, and our market-leading solutions in the grocery, chain drug, and general and specialty retail segments.

In addition, the Board announced that Martin Ellis, who has been president and CEO of Agilysys since 2008, will be leaving Agilysys to pursue other career interests. Martin will continue to serve as special advisor to the Board chairman during this transition. We thank him for his contributions during his eight years with the Company, and we wish him all the best in his future endeavors.

In my new role, I will be communicating to you going forward as the Company continues to make progress with its more focused strategy. As a member of the Company’s Board of Directors since 2009, I have specific familiarity with the business and the needs of our customers.

I look forward to our continuing relationship and I thank you for allowing Agilysys the opportunity to serve you by helping to create value for your business.
