The service is designed for those who use Google Gmail, Google Docs, Google Sites and Google Calendar in a business environment and starts off with contributions from 50 software developers, including Atlassian, NetSuite, Skytap and Zoho.
"Tonight, what we're doing is we're announcing a business-to-business marketplace for Google Apps users, where the idea is that we want to help users get more applications for Google Apps from third-party developers," said Chris Vander Mey, Google senior product manager. Among the applications is a small business payroll system from Intuit, called Intuit Online Payroll, and Box.net's self-named content management system.
Users of Apps, Google's set of online office tools, can link to an application via the user interface in Google applications, offering benefits like single sign-on and sharing of data between Google Apps and third-party tools.
Participation in Google Apps Marketplace is open to customers of the Premier, Standard and Education editions of Google Apps.
"We expect [the marketplace is] going to significantly help Google Apps adoption and also help adoption of our partner apps," Vander Mey said. "We're going to bring 25 million users to these partner companies."
Google began offering online applications five years ago, and reached the 25 million-user mark last weekend, said Vender Mey. More than 2 million businesses use the applications, he said.
Google will pass on 80 percent of revenues from Google Apps Market sales to participating partners and keep the remaining 20 percent.
Some of the other application partners include Aviary, Batchbook, Bookfresh, Expensify, OfficeSync, Shoeboxed.com, and SuccessFactors.
