Good day, debbiesap.
Have you already recorded the supplier credit? If not, follow these steps to record in in QuickBooks.
- Click the Plus icon in the upper-right hand corner of QuickBooks.
- Select Supplier Credit.
- Enter all other details, then click Save and close.
Then, follow these steps if you want to apply it on an unpaid invoice/bill:
- Open the bill or supplier's invoice.
- Scroll-down to the Credits section and select the existing credit.
- Click Save and close.
If the transaction has already been paid, follow the same steps above on future invoices/bills.
More details about on how this process works are discussed here: How Do I Handle Supplier Credits And Refunds?.
I'd be glad to get back here if you need more help.
