I like that it automatically calculates my time off when calculating vacation hours! It's also very easy to use once you learn how everything works together in one program instead of having two or three different programs/apps open at all times. The interface can feel overwhelming if not used often enough but is really simple after getting familiarized with what each button does (which isn't too difficult). We have been using this software since we started running out side jobs as well as office services such an accounting / payroll & bookkeeping work so far its worked great!!
