Supplier payment not appearing on a bank statement
I'm here to help, ColinD.
You'll want to check the Audit log report to see the history of that transaction. The report will also display if the transaction was deleted or voided.
Go to the Gear icon locate in the upper right-hand corner.
Under Tools, click Audit log.
Select the Filter drop-down menu.
Choose the User, Date, and under Events put a check mark on the Transactions box.
If the payment was deleted, then you can re-create it with the correct amount. However, if the transaction was excluded and deleted from the Banking or Transactions page, you'll want to import it manually.
