I love how it is easy for my supervisors or managers in charge of our accounts/clients can view all available reports from any device they choose at anytime without having to wait until we have an internet connection (which sometimes takes minutes).
Also being able to send emails straight into their inbox instead of waiting till after hours when everyone has left work makes life easier! Nothing really but maybe adding more features would be nice like some sort of dashboard with filters so accountants could see what's been done by which agent over time etc?
