How do you enter a vendor credit memo, or adjust a vendor invoice aleady entered?

Hi there, @RetiredLF.

Let me guide you on how to enter a credit memo in QuickBooks Desktop.

1. Go to the Banking menu, then tap Make Deposits.
2. If the Payments to Deposit window appears, click OK.
3. In the Make Deposits window, select the Received from the drop-down and choose the vendor who sent you the refund.
4. In the From Account drop-down, select the appropriate Accounts Payable account.
5. In the Amount column, enter the actual amount of the Vendor check.
6. (Optional) Enter a memo, check number, payment method, and class.
7. Hit Save & Close.

Then you have to record the refunded amount:

1. Click Enter Bills on the Home page.
2. Choose the name of the Vendor.
3. Enter the amount of the bill.
4. Choose either of the two tabs:
   1. Expense
   2. Items
5. Add the specific details of the bill.
6. Click Save and Close.

What's the “appropriate Accounts Payable account”? We have only 1 Accounts Payable account. This article is way too simple. It has only one value: to point me to the other article.
