My integration with Stripe broke and added 99 duplicate invoices (and marked them as paid) - how can I bulk delete the 99 payments so I can delete the invoices?

Thanks for posting here in the Community space, @dh-spare.

Allow me to walk you through the process of bulk deleting paid invoices in QuickBooks Online (QBO).

If you were referring to clearing the duplicate invoices from the Sales menu, you can use the Batch action function to delete multiple invoices. Here's how:

1. Go to the Sales menu, then select the Invoices tab.
2. On the Status dropdown, choose Paid to show invoices linked to payments. You can also filter to a specific time on the Date dropdown.

    

3. Check the invoices you want to delete (or check the box column to select all of them).
4. Click the Batch actions button. 
5. Select Delete.

    

6. Hit Delete.

On the other hand, if your duplicate invoices are seen on the App transactions tab from the Transactions page, you can simply use the Undo option to delete them. Here's how:

1. On the Transactions menu, go to the App transactions tab.
2. On the Categorized section, tick the checkbox to select all transactions.
3. Click Undo.
4. On the For review tab, you can exclude your transactions by selecting all of them and then clicking Exclude.
5. Once they're in the Excluded tab, you can select all and then delete them.
