My business was growing beyond what we could manage with pen and paper. We were introduced to MISys through our SAGE rep. We spent several months reviewing MISys and another six months receiving training and getting ready to implement. We have been live since the first week in Jan and 99% of our problems were self inflicted. We are a job shop manufacture with varying requirements from our customers and even more so varying needs from our suppliers. Every software has its limitations but our support from MISys help us understand the limitations and they worked with us to adapt either MISys or our procedures so we could get the maximum benefit possible. If your looking for a MRP system with reasonable flexibility and great customer service, you need to give MISys a hard look.
