Below is an example displaying that the amount owing on the GST draft report doesn't match the amount owing in the payment processing screen.
The most common reason this occurs is when invoices are created with the ATO as the client, which have also included GST.
To identify the cause, run a ledger enquiry with your GST period set as the date range, and the client as the Australian Taxation Office.
From here we can identify three creditor invoices entered incorrectly, and you can now go back and amend them accordingly.
In the event that nothing incorrect shows in the ledger enquiry, please give our helpdesk a call.
