I hope you're doing well today, petercat.
I'd be happy to share some details about the vendor credit.
In QuickBooks Online, you have the option to unlink or delete a vendor credit that is linked to a bill payment.
Here's how:
- Go to Expenses > Vendors.
- Select the vendor's name and open the bill payment.

- In the Bill payments page under Credits, un-check the vendor credit.

- Click Save and close.
- In the Transaction List, select the Vendor Credit.

- Hit More located at the bottom and choose Delete.
- Click Yes to confirm.
