By mistake in several invoices the amount has been duplicated, we need to make corrective invoices. How can we make them?

Hi shop-followthepl,

Thank you for taking the time to visit the Community!

We're unable to do corrective invoicing in QBO. You may want to consider issuing replacement invoices with the correct amounts and sending them to your clients. Keep a PDF copy of the old ones and attach them to the replacements for your record.

To delete the invoices with incorrect amounts, open each of them, click More at the bottom, and choose Delete.

Feel free to go back to this thread if you have other questions in mind. Have a good one!
