Hi there, @garethevans84-ho.
It's nice to see you here in the Community! I've got the steps you need to input a credit note from a supplier.
You have to use the Supplier Credit option from the +New menu. Here's how:
- Click on the + New button. and select Supplier Credit.

- In the Supplier field, choose the appropriate supplier name.
- Fill in the Payment date, Amount, and Category details or Item details fields (usually, this is the category, product, or service you’re getting credit for).
- Select Save and close.
Then, you can apply this amount to your bills, checks, or expenses. For the detailed steps, refer to this article: Record Vendor Refunds or Credits.
Otherwise, if you receive a credit on a credit card, utilize the Credit card credit option instead. You can also find the instructions on the article above.
Keep me updated on how it works for you after following these steps. I'd be glad to assist you further if you have further concerns about handling vendor credits. Wishing you a good one!
