Shopify Refunds Guide
To process a refund, go to your Admin console > Orders > click on a order > click on "Refund"
The process should be the same as for any other payment method used by a customer to purchase an item.
Refunds should go from pending to processed. Note, Tensile may take up to 5-7 business days to process a refund. Please contact support if you need a refund processed sooner.
