Wow .. this is even worse than SAP Welcome back to the 90s, only now in the palm of your hand. Does not comply with common practices for mobile apps, is not even remotely intuitive and offers little convenience along with zero automaton. Search mostly do not work, every employee needs to learn account numbers. Heck, pressing "back" from any screen logs you out. Registering a single receipt takes dozens of key presses. Avoid!
Awesome! friendly, simple and useful design.
