I've been looking for a simple CRM system to use at my day job for the last couple of years. My current vendor provides a free version of Salesforce, which seems ok, but isn't integrated into any other systems and doesn't integrate with most others either (ie. HR, payroll). I've tried many others, but none seem to fit the bill. I am so impressed with Cheqdin that I decided to give them a try. The web interface is easy to navigate and the dashboard is easy to see how you're doing compared to other tools. It has a nice blend of simplicity and complexity. For example, when you add new clients, the way the form works allows for both'regular' contacts (phone number and email) and mobile contacts. The mobile contact information is optional, so if you don't want to share it with your client, you don't have to. And the data fields are fairly self-explanatory. You don't have to become a 'programmer' to use it, which I like because I find that too many vendors make it so hard to get anything done. There is a learning curve, but I've had no problems setting it up.
