I love that this software is so user friendly, it's not as complicated to utilize or use in comparison with some of our other systems we have used previously. It can be very helpful for contractors who are new at using spreadsheets such as myself! We were able to create an inventory system which was easy enough for us all to understand but still had features like time cards built into it if needed. The only thing i disliked about buildersys (and any program) would be when you first set up your database there seems to always come errors along way until they get fixed- however once everything works great its awesome!!
