Salesforce will be making a whole bunch of partner announcements at an event in San Francisco next Monday. We’ve been informed that the on-demand enterprise software company will begin reselling Google’s Web-based applications such as Google Docs to its customers. These Web apps will be available within Salesforce.com and tightly integrated into its service.

Such a deal makes a lot of sense. Salesforce customers can already manage their AdWords campaigns from within Salesforce.com, a deal that was announced last summer. Salesforce wants to get as close to Google as it can. And Google wants to sell its apps to enterprise customers (Salesforce has 41,000 of them).

While Salesforce CEO Marc Benioff might be happy to sell Salesforce to Oracle for $75 a share, he might be even happier to sell it to Google. Buying Salesforce would certainly turbocharge Google’s efforts to sell into enterprise accounts.

This integration news doesn’t come entirely out of the blue. Last March, Google Operating System noticed some signs of the coming integration within certain CSS files used by Google Apps. References to Google Apps were also found in Salesforce services.

Salesforce refused to comment on the announcement and we’re still waiting to hear back from Google.
