I have created 2 invoices in error how do I delete them?. Thank you in advance

Not a problem, simeon. I can guide you through deleting an invoice you mistakenly created in QuickBooks Online (QBO) in the easiest way.

Know that deleting a transaction will completely erase this from your books and won't affect your account balances. To begin, please see the guidelines below:

1. Go to the Sales menu and navigate to the Invoices tab.
2. Locate the transactions you want to delete.
3. Under the Action column, click the dropdown arrow and select Delete. Then, press Delete to confirm.

Moreover, once you re-created the invoices correctly, you can proceed to record their payments once they got paid by your clients. Keeping it as a practice will maintain the accuracy of your books.
