Hi peppermill,
I can see how duplicate payments can cause discrepancies in your books. Don't worry, I'll help get to the bottom of this.
The common cause for duplicate payments with Square is having an integration app plus Square connected as a bank in QB. Having an integration app and the bank feed will cause these unwanted duplicate transactions. To fix this, you'll need to use one method to sync your Square transactions with QB. Let me know if this is the case and we can take it from there.
In terms of the duplicate payments, you'll have to manually delete each of the duplicate payments/invoices from QB.
To delete the invoice and payment:
- Go to Sales tab and choose Customers.
- Click on the customer's name.
- On the Transaction List, open the payment you've processed.
- At the bottom part, click on More and select Delete.
- Hit Yes to confirm.
Do the same process for the invoices. If you delete transactions that were previously reconciled, the next reconciliation beginning balance will change, and there is no way to recover or restore deleted transactions. The only record of the change is in the Audit Log.
Check this article for more details: How to void or delete an invoice or other transactions.
