Any business comes to a point when keeping a list of clients in an Excel file becomes counterproductive. Getting an expensive CRM system, like SalesForce, which costs $60 per user per month is out of the questions. A number of great free opensource CRM systems are available, but this option is limited only to those who have strong coding skills. Otherwise you’d have to pay $50-$100 an hour to an IT guy to set it up properly for you. A free hosted CRM is the only option available.
