I like that it's very easy to use, even for beginners! It has all of my contacts in one place so there are no more emails going back-and forth between us trying to find someone who can do what we need done next.
The only thing I dislike about this program is how slow the system sometimes runs when you have lots of people working at once (not just during peak times). We've been able to get our jobsites up faster than ever before because everything was already set up ahead of time by another team member using their own software.
