We have been using JobBoss for 6 years and it has made a world of differnce for us. Before we used Quickbooks, but as we grew we needed more. Jobboss offers several different modules and they come with a pretty good price. The best thing about it is how the program flows from one module to another. Quote,Job creation, purchasing, scheduling, shipping, billing. I can honestly say that it has better organized our shop and would recommend it. When a customer calls to check on something we can usually pull up the information in seconds. The only drawback is the cost. They charge a yearly fee for support and updates. We stopped our maintenance/support contract a couple of years ago.
