Click on universal add button ‘+’ and select refund. A refund window will open with ‘Credit Memo’ as the default refund type.
Option 2: From Customer Record
Navigate to the Refunds section and click the add ‘+’ button to create a new credit memo for the customer. The customer information will automatically be pre-filled for you.
Either way you choose, the same refunds screen will pop up. Select a Product or Service and tax (if applicable) that will issue the refund amount as it is required and Save.
