Google rolls out Google Apps Marketplace

Search giant to target Apple and Microsoft with business apps store

Google fires next shot in App Store war

Microsoft's Office suite may have its work cut out following the release today of search giant Google's new business Apps Store.

The service, called Google Apps Marketplace, will integrate with its Google Apps software suite which is currently used by more than two million businesses.

The Google Apps Marketplace will be open to developers and more than 50 companies have been involved in the creation of business apps on the platform.

It will offer business software such as a project management application, a tax and payroll program, an electronic fax program, an e-signature service, and a design tool for Google Docs.

Third-party applications include the following, according to a blogby Chris Vander Mey, product manager for Google Apps Marketplace:

Charges for participating developers in Google Apps Marketplace will be a fixed $100 (£67) for unlimited applications.

Google Apps currently includes Gmail, Google Calendar and Google Docs, and the new applications store will be competing with Microsoft's Office Web Apps and the new version of Office 10, which launches in June.

Some of the third-party applications will include features that integrate with business's back-end data stores.
