When making a deposit for a customer, they had an incorrect version of the invoice and paid additional that was unneeded. In the deposit you can create a Credit note, but the credit note can only then be used when making another deposit from that customer rather than being able to include that over payment back to them along with invoices we owe to them without using Asset accounts for pre-paid expenses which does work but does not allow for the same visual as utilizing the existing credit on account
