By showcasing on the AppExchange Marketplace, ISVs often provide free apps, which help drive traffic and interest in their core products, which complement Salesforce CRM, and are usually provided as web-based solutions in the same way as Salesforce.

These complementary applications are typically deployed alongside Salesforce CRM in support of a specific business process or function. For example, incentive and commission management, project management, product configuration, expense management, address checking, and so on are all examples of apps for Salesforce, which are available from the AppExchange.
