One of our main issues with the new invoice is the limit of custom fields to 3. We had just a few more than that which were important for our workflow. The change was also sudden and without warning. Most of the processes we use are now buried in side panels and drop down menus. The button that needed to be pressed to receive a payment was right where you needed it to be. Now it is a wild goose chase to find it. The only thing that is good about it is that it looks a little bit better. Unfortunately, the functionality is far worse, takes more time, and came without warning during one of our busiest times of the year. Total failure in our opinion.
