On the customer order page, click the "Refund" button.
2. Do not select a product to be refunded in this page, unless you are cancelling or removing it from the customer's orders. If you do this step, it will remove the product and it will not be fulfilled and shipped. Only do this step if purpose is cancelling a part or the complete order.
3. Put the refund amount on the dedicated box, and uncheck the checkbox saying "Send a notification to the customer". Purpose is to not send customer a refund notification email since the main CRM for issuing refund is checkoutchamp. They do receive refund confirmation on that CRM.
4. Make sure checkbox is unchecked. Click the refund button.
5. You will see that the refund was issued but there is not email notification sent.
