I like how it's easy to use, has great customer service and is very user friendly. Nothing! It does what it says so far and I haven't had any problems with it other than a few minor issues here and there. They are always willing to help and give you advice when needed. I have used this software in the past but they were using an old version of it and I didn't realize it wasn't updated since then. The most helpful thing about this program is that it is extremely easy to use because it is so user-friendly. Very simple to learn and implement. This makes my job easier as well because I don't have to call anyone or wait for someone to come out and help me with the program.
