When a company wants to improve upon its customer care and enhance its ability to market products and services to the people who have already made purchases, customer relationship management (CRM) tools are the natural choice. CRM tools help a company to maximize the effectiveness of their marketing. These tools make it possible to find out what a person has bought in the past and use that information and the timing of their transactions, along with other information such as the season of the year, to make them offers on other products and services that they might also want to have. The CRM tools developed by Fat Free CRM make all of this possible. Their open source CRM software is easy for new users to figure out. As one of the top ten providers of open source CRM software, Fat Free CRM offers exemplary service and technology that is up-to-date.
