Problem:
When end of day is run, the Invoice Payment Register is reporting one amount, but it doesn’t match what was brought in to Quick Books. What is happening to cause this?
Changes were made to the sales orders associated with the invoices that were already in Quick Books.
Any changes made to a sales order,will automatically cause the invoice to be updated with the changes. The invoice then gets flagged to be re-exported.
The changes will not be imported to QB because the invoice is already there. The updated invoices are listed on the Invoice Payment Register to let you know that something has changed and that QB needs to be updated manually.
