Salesforce.com is a provider of SaaS-based CRM products, as well as having a PaaS offering, Force.com. Salesforce.com's CRM solution is divided into several applications including Sales Marketing, Service, and Partners. Pricing is on a per-user basis, and the rates and different support packages are posted online.

Salesforce.com has more recently begun to provide Paas-based services through the Force.com platform. Force.com allows external developers to create add-on applications that integrate into the main Salesforce.com applications, and are hosted on Salesforce. com's infrastructure.

Applications are built using Apex, a proprietary programming language for the Force.com platform. Pricing is on a per developer basis, and different support packages allow for varied levels of storage, API calls, and so forth. AppExchange is a directory of applications built for Salesforce. com by third-party developers which users can purchase and add to their Salesforce environments. As of May 2009, approximately 800 applications are available from more than 450 independent software vendors (ISVs) via AppExchange.
