I'm glad to see you here in the Community, d.riseberg.

Let me provide you with easy steps on how you can undo the credits and apply it to the correct bill.

You can remove a vendor credit from a bill if it is wrongly applied.

Here's how:

1. Locate the appropriate vendor credit.
2. Select the Credit radio button to change the transaction type to credit, then select Save & Close.
3. Change the transaction back to credit by selecting the Credit radio button, then Save and Close.
4. When prompted about changing the transaction, select Yes.
