As its name implies, Fat Free CRM is a minimal and customizable but functional system. Out of the box, it features group collaboration, campaign and lead management, contact lists, and opportunity tracking. It’s probably more than enough for smaller businesses and other organizations. Fat Free CRM does have one of the most attractive and easiest to use interfaces of any CRM. A number of plug-ins are available for Fat Free CRM. There is no hosted version of Fat Free CRM, so organizations need to download and install it on their own servers. Before doing that, however, they can give Fat Free CRM a try using the online demo.
