Can someone help? I need help to change an invoice number to match an invoice that was deleted in error?

Hi @Barbarita57.

Thanks for posting to the Community. Let's turn on the Custom transaction numbers on your sales forms so that you can change the invoice number. You can set it  up under the Sales settings in Account and Settings.

Here's how:

1. Click the Gear icon on the top right.
2. Select Account and Settings and then go to Sales.
3.  Under the Sales form content section, turn On the Custom transaction numbers by checking the box.
4. Click Save.

Once done, you can now change the invoice number and save it.

Also, I'll be adding this article as your reference when recording customer payments: Record invoice payments in QuickBooks Online.

In case you need to create recurring invoice transactions sooner or later, you can check this article on how to make them: How to create a recurring invoice and manage recurring transactions.
