we issued an incorrect invoice to a vendor and need to correct it. we've been told that we need to do a credit note, then issue a new one. seeking guidance on that

Hi, info2392. While you can technically enter a supplier credit to offset the wrong bill and then enter a new one, that’s often the long way around. The easiest way to correct it is by simply editing the bill. Simply open it and make the necessary changes.

You also have the option to completely start over, by clicking More>Delete. Deleting the transaction permanently removes the entry.

The option above will help keep your books clean without extra clutter transactions. However, if you want to proceed with applying a credit, you can follow refer to the Option 2 section of this article for the steps: Enter supplier credits and refunds in QuickBooks Online.
