I like that it is very easy to use, no training required! It has all of my subcontractors' contact info in one place so we can easily communicate with them as needed; this saves me time when needing information about work progress or final payment status for our clients. Also great if you have multiple companies performing your project - each contractor's own sub-contracting system helps keep everything organized & under control. This software was not intuitive at first but after some research tutorials were found online which helped tremendously. There are tons of features out there (including other free ones) however most don't come close to what Buildersys offers. We used this program before switching over completely from Excel spreadsheets to build management programs using builder SYS.
