I really like that it is easy to use! The interface makes sense so anyone can understand how things work quickly without trouble.
It has helped us keep track of our expenses as we have been working with remote clients all over the country who need access from anywhere at anytime. We've had issues when they first launched but those were resolved fairly fast once they got feedback about what was going wrong. You do get used to using this software pretty quick though because everything works well for keeping track of costs/expenses etc.
