I love that it is very simple to use, easy access from anywhere in my mobile phone or computer! It has all of your accounting information already set up with you as soon as we start working together which saves me time when preparing our monthly reports.- Nothing at this point- There are some minor glitches here an there but they can be fixed easily if caught early enough (we have been using them since 2012).
The fact that everything gets saved automatically makes things easier than having paper documents scattered around everywhere.
