I like that the system is very simple and easy to use. It is also very flexible and can be changed to fit your needs. The customer support is also very helpful and knowledgeable. Nothing at this time. I can't think of anything to dislike about the system. It is a great tool for scheduling appointments and managing the appointments. It is also very easy to use. I have been able to decrease the amount of time it takes to schedule appointments by using ibis scheduler. The time savings is very great. I am able to schedule more appointments in less time.
