I love how easy it is to use this software in our department of over 2k employees who do nothing but process invoices as well as approve payments from various vendors that we work with. It's also very user friendly for someone new which has helped out alot since most people have been using other programs before they start working here. Nothing really so far! Maybe more training or help guides would be good. We are able to get all documents signed off without having to go back through each person individually every time an invoice comes up. Also helpful because now those same individuals can approve them right away!
