I like that it allows you to keep track of your warranties easily. The system has many helpful features such as being able to create new users or add/edit existing ones. It also makes keeping up with all paperwork easy! Nothing so far. If used correctly this program will help you save time and money while improving the service department. We are saving money because we can see our current inventory better than ever before and we are saving time because there isn't much manual work involved anymore when dealing with repairs.
