Open a New Credit Memo
From the + menu, select Credit Memo to create a new credit memo.
Choose a Customer
In the credit memo window, choose the customer you’re giving credit to by selecting a customer name from the drop-down menu.
Select a Product or Service
Beneath the column header labeled “PRODUCT/SERVICE” click on the drop-down menu and choose the Product or Service you’re issuing credit to the customer for.
Examine Credit Memo Details
Check the Amount column to ensure it’s the correct amount of credit you want to issue to this customer.
Save and Close (or) Save and Send
When you’re finished with the credit memo form, you can choose Save and Send at the bottom of the screen to send the credit directly to your customer.
Now you can choose a Gmail contact as the customer or vendor on any of your transactions.
Retrieve Credit Memo Later
To retrieve this credit memo later, go to the home screen and click Customers in the far left tab to navigate to your Customer list.
In your Customer list, find the customer you credited and click on their Name to open the Customer detail window.
In the Customer detail window, you’ll see a list of all the transactions you have on record with this customer — you’ll notice QuickBooks has added the credit memo at the top of the list.
