The people at ClinicTracker are really the best! Very honest and straightforward. They have helped us with every issue we've had, sometimes within minutes! I really like that they are extremely knowledgeable about the system and can explain anything and everything.
There is nothing I don't like about the vendor. Only issue with the product is that navigation is not smooth. It can be hard to find things, or it takes a number of clicks to get where you need to go. However, ClinicTracker is open to new suggestions, and they make changes for you! They really listen to the customer.
We looked at a lot of systems. Do the same. Do not put stock in what the salespeople tell you about their systems. Try the system out and see if it works for you.
