Salesforce.com is rolling out features that allow customers to share sales leads, product info and other communications securely.

With the site's subscriber base expected to pass the one million mark by the end of December, the firm hopes to turn its membership to an advantage by inviting them to make transactions and share information, according to ZD Net.

The service focuses primarily on sharing and building sales lead and CRM-related information.

Dell and DoubleClick are already on board with the new features. Connections between businesses cost just $100 a month, with the inviting party paying the fee.

The $100 fee pales in comparison to the high numbers company-to-company IT projects can cost. According to IDC, integration issues cost enterprises $3 billion in 2006.
