15 Best Free and Open Source Linux CRM Software

For a profit-making business to be successful, the customer must rank as the most important part of the chain. After all, without customers the business would not even exist.

In simple terms, Customer Relationship Management (CRM) represents the way an organisation keeps track with its existing and potential future customers. CRM software offers the means to support these processes. This type of software stores information about customers. But its functionality far extends that of say a traditional database. It also allows companies to measure and control contacts with customers, to provide the flexibility to get the right information to the right individual at the right time.
