Hello, user261022.

I know how to handle supplier refunds in QuickBooks Online Simple Start.

You can create a bank deposit. Then use the same account you did for the original expense. This will reduce the previous expense that was covered by the refund you just got.

Here's how:

1. Click the + New icon.
2. Select Bank deposit.
3. In the Account section, choose the correct bank account.
4. Fill in the date.
5. In the Add funds to this deposit, enter the supplier in the Received from column.
6. Choose the same expense account you use on the original expense in the Account column.
7. Enter the amount of the refund.
8. Once done, hit Save and close.
