The ease of use of this program. It's very intuitive and it makes it easy to find what you need. I like that it is able to sync with other programs such as Outlook or Excel with ease. It is difficult to find information on how to do things. There are so many options for each function that it can be hard to know where to look for answers. This software has helped us track our time in a much better way then we were doing before. We used to have to write down all our hours and then add them up manually. Now we just enter our time into this program and it automatically adds it up for us.
