Refunded Double Payment

I can help you with recording the refund you've received from your vendor, @jlangr.

You can add this by recording a bank deposit for the check that you've received, and then a Bill Credit for the refunded amount. Once done, link these transactions. 

Here's how to record the check that you've received:

1. From the Banking menu, click on Make Deposits.
2. Select the OK button once the Payments to Deposit window appears
3. In the Make Deposits window, click the Received from dropdown and choose the vendor who sent you the refund.
4. In the From Account dropdown, set the appropriate Accounts Payable account.
5. In the Amount column, enter the amount of the check.
6. Click on Save & Close once you're done.

Then, follow the steps below on how to add a Bill Credit for the refunded amount:

1. Go to the Vendors menu and look for Enter Bills.
2. Click the Credit radio button.
3. Set the Vendor name.
4. Select the Expenses tab and enter the Accounts on the original bill.
5. Provide all the necessary information. 
6. Click on Save & Close once you're done.

Lastly, check out these guidelines on how to link the deposit to the Bill Credit:

1. Go back to the Vendors menu and click on Pay Bills.
2. Verify the Deposit that matches the Vendor check amount.
3. Choose Set Credits and apply the Bill Credit you created earlier then select Done.
4. Click on Pay Selected Bills, then select Done.

Thank you for the response. The vendor had a negative balance already, so I did not have to make the additional credit. Putting the vendor name in the deposit and using Accounts Payable for my account removed the negative balance from the Vendor's account, which is what I needed. Thanks again.
