Unlike most CRM software solutions, Fat Free CRM is an entirely open source program built from Ruby on Rails. In its basic form, it provides companies with collaboration features for a group, lead management, campaign managements, opportunity tracking and contacts lists. The ultimate goal of Fat Free CRM is to promote innovation within the CRM field by giving users access to clean code that can be added on to by any developer that wants to contribute. At its core, the Fat Free CRM program is noted to be one of the most simple-to-use, innovative software options around. While not built for large companies, it offers small businesses everything they need to maintain and organize all of their customer relationships. These features include the ability to organize customer accounts, leads, contacts and opportunities. It can even automate the management of certain activities, such as daily tasks, meetings, follow-ups and phone calls.
