I can guide you with recording your vendor refund, @desandbriddoyle-. 

If you have received a refund from a vendor, the way you record or categorize it depends on how you recorded the initial expense or transaction. Please take note of the following information: 

• If you recorded it as an expense or a cheque, you can record a bank deposit. Enter the amount and the category or account that you selected on the initial expense or cheque.
• If you received a refund on a credit card, you can enter a credit card credit. 
• If you recorded it as a bill, you can apply a supplier credit towards any open or future bill.

Here's how to record a bank deposit if you recorded it as an expense:

1. Go to the + New button and select Bank Deposit.
2. Scroll down to the Add funds to this deposit section. Enter the amount refunded by the supplier and choose the Category/Account that you selected on the initial expense or cheque.
3. If this refund was for an expense that you linked to a customer or project, tick the Track returns for customer checkbox, then select the customer or project. 
4. If you deposited customer payments for invoices into the bank account along with the supplier refund, add them in the Select the payments included in this deposit section.
