If a payment is added directly to a supplier invoice it appears as a transaction in the bank account, and when the bank statements are uploaded the payment is added a second time to the bank account. Should I just delete the second transaction?
The problem then is that a cheque could be written out and allocated to a supplier invoice long before it is cashed, so if the second transaction (the actual date the payment is cashed) is the one that is deleted then the payment date on the invoice and in the bank account on Quickfile will not match with the actual bank account.
