Returning a single item to inventory
You can return an item back to your Shopify inventory with Edit Order. By default, items removed from an order would automatically be restocked.
How to return a single item to inventory:
1. On your Order page, click on More actions, then Edit Order.
2. Hover over the item you would want to return and click on the “Trash can” icon.
3. Once you have removed the items you want to return to your inventory, click on Save.
The difference in price would be automatically refunded to the original payment method.
