I’ve been using stack for a couple weeks now and have previously had koho for awhile,
The one major change stack should strongly suggest doing it allowing there customers to send e-transfer a to non stack cardholders, and not just stack to stack (not everyone wants to have a stack card) and from what I’m seei g maybe allow there card users to pay bill with there card and not just load threw a bill which sound very confusing to do
Koho o the other hand does allow you to do all this so it’s what your personally looking for
