Interface with Zelle and other such payment systems, so they are reflected in our Income reports.
I have no idea how WA would do this (nor why WA would want to, now that you offer your own card processing system), but it would be helpful, at least as the WA financial reporting system goes. This year, our organization began encouraging Registrants to pay via Zelle, which charges neither party a processing fee. The difference is thousands of dollars in our bank account (paying for our WA account ;-) . Those payments are received instantly and go directly into our account, so they are relatively easy to enter into our books. Yes, we must keep separate books, since we accept checks and cash for many events, or at them. But it would at least help us track trends in our cash levels and flow periodically.
