when a credit note needs to be refunded to a customer, particularly in cases where the refund is processed offline, the system allows you to record this transaction for accurate financial tracking.
Creating a Refund for a Credit Note
- Navigate to Invoicing > Credit Notes.
 - Identify and select the credit note you wish to refund.
 - Click on Refund button on the right panel to initiate the refund process.
 - Enter the refund amount. This can be the full value of the credit note or a partial amount.
 - Click Save.
 
Note: It's important to record the exact refund amount, whether it's a partial or full refund.
