Business users of Google Apps might find this intriguing--Google has opened up a Google App Marketplace, which will offer business-oriented third-party add-ons and supplements for Google’s online application suite.
The Marketplace contains apps from 50 companies, including eFax, Concur, Intuit, and Jobvite. The applications are tightly coupled with Google Apps, allowing seamless integration with Gmail, Calendar, and Docs. Vic Gundotra, a vice president of engineering at Google, says “The Applications Marketplace makes it easy for domain administrators to discover and install new software and have it integrated into Google Apps.”
Google charges developers $100 for placing an application in the Marketplace, and keeps 20 percent of the proceeds. Developers are free to name their own price for their applications. Google doesn’t expect to get rich(er) from the Marketplace, rather it's looking for the Marketplace to promote Google Apps and the software applications of its partners.
Google claims 25 million Google Apps users, in more than two million businesses. Google concedes, however, that only “hundreds of thousands” are paying customers.
