Refunds in Customer Portal
Refunds in Customer Portal are not automatic and must be manually issued.
Refunds after edits
When your customers decrease the quantity of an item or entirely remove an item from their paid order, a banner will show them that a refund is due. They will also receive an email notification that their order has been updated.
Refunds after cancelling an order
When your customers cancel their orders, a banner will show that their order was cancelled. They will also receive an email notification that their order has been cancelled.
If a refund is due after your customers have edited their order (i.e: they removed an item or cancelled the order), you will receive an email notification with a link to the order page. You will have to manually issue the refund through your Shopify admin. The refunds are not automatic.
Note: In your Customer Portal's settings, the email notification section allows you to receive email notifications to a specific email address of your choice. If no email address is entered, the email notification that an order was cancelled or edited will be sent to your admin's email address.
