What if the client wants the payment back. We recently had a client pay off the same invoice twice. It was a substantial amount. Then when they realized their mistake they took that amount back out of my account. It was pretty disturbing, but this is a great client and they were changing banks at the time. Can I just add the debit and credit to the same account? (The reason I ask, it it seems that anytime you mess with any debt or credit in the clients account it turns into a nightmare of corrections.)
