Struggling to work out how to enter some refunds.- a train travel partial refund- a reward credit from our bank-partial credit card refund for a productThanks

Hello, @jen21.

There are two ways to handle refund transactions in QuickBooks Online. This will vary depending on the situation that you're in. 

If there's a bill associated with the refund, and you're going to pay a lesser amount to your vendor,  you can create a vendor credit and apply it to the transaction.

Please take these steps to achieve this goal:

1. Go to the Plus (+) icon.
2. From the Suppliers column, choose Supplier Credit.
3. Select the supplier who issues the credit or refund.
4. Enter the date and amount of the credit.
5. In the Account Details section, select the expense account used on the original bill.
6. Click on Save and Close.

However, if the transaction is solely a refund to your vendors' expense, you can process a bank deposit directly and use the expense account as the account affected.

To do that:

1. Select the Gear ⨁.
2. Choose Bank Deposit.
3. In the Add funds to this deposit section, fill in the following fields:
   • Received from: Select or enter the supplier name.
   • Account: Select the Accounts Payable account.
   • Amount: Enter the cheque amount.
4. Select Save and close.
