Thank you for the taking time to reach out to us, sophie25.
I appreciate you for providing screenshot and details of your concern. Let's get this straightened out for you.
Since you're using a third party application to download invoices and receive payments to QuickBooks Online (QBO), we recommend contacting them so they can help you look for ways on preventing these duplicates to happen in the future.
For now, you can manually delete those duplicate invoices in QBO. I'd be happy to walk you through the steps on how to delete a duplicate invoice.
Here's how:
- Find and open the duplicate invoice.
- Click More at the bottom.
- Select Delete.
- Click Yes.
You can also check out this article to learn more about deleting invoices and other transactions: How to void or delete an invoice or other transactions.
If you have any other concerns, don't hesitate to let me know. I'm always here to help.
