Currency Exchange Differences and fees

JMillar

I'm flummoxed as to how to solve this problem. I'm in Canada and we have one client that we bill in US funds. I tried using a Paypal account as the intermediary account like Payments by Wave does, but the amounts paid don't match what the invoice says, so I can't just mark the invoice as paid. In addition, our first invoice has an overpayment that needs to be dealt with (we gave a credit on the next invoice).

I then tried to split the transaction and choose the invoice from in there. It let me choose the first invoice, but it is not showing me any of the other unpaid invoices in there except for a few later ones (not the right client). What is the best way to handle this, and the transaction fees as well?
