Hello @Leena_Chandra
Issue Summary:
You’re trying to refund an order via Shopify Admin > Orders > Refund, but the error message says:
“Refund request is not processed due to invalid amount.”
From the screenshot:
. All items have been removed or added to a return (blue info box).
. The only selectable refund is shipping (₹55).
. The refund amount shows ₹0.00 and is not editable (greyed out).
. You mentioned wanting to manually add the refund amount, but Shopify won’t allow it.
Why This Is Happening
This issue usually happens when:
-
All line items have already been returned/refunded — Shopify thinks there’s nothing left to refund.
-
Shopify locks refund inputs once it thinks the refund is complete or all items are handled via returns.
-
Shopify only shows the shipping refund if there are no items left to refund.
-
So even if you received the money in your bank, Shopify won’t process a refund unless items are selected or amounts are editable, which they aren’t here.
Solution Options
Option 1: Manually refund via Payment Gateway
Since Shopify won’t allow a manual refund here, do this:
-
Go to your payment provider dashboard (e.g., PayU India).
-
Manually issue the refund to the customer.
-
Back in Shopify, go to the order and:
. Click “More actions” > “Add timeline comment”.
. Leave a note saying:
“Refund of ₹XXX processed manually via PayU India on [date]. Not processed via Shopify due to refund screen limitations.”
. Optionally, add a staff note or tag like manual-refund.
This keeps your order records clean for bookkeeping.
Option 2: Use Shopify Partial Refund (if applicable)
If for some reason Shopify hasn’t recorded a refund on the product items:
-
Go to the order’s return section, click “Create return”.
-
Select items and set quantities to return.
-
Once the return is created, the “Refund” screen will allow editing the refund amount again.
Note: This only works if Shopify still thinks items are refundable. In your case, the message “All items have been removed or added to a return” implies they aren’t.
Suggested Configuration/Setup Tips
-
Avoid marking items returned unless sure a refund will be done via Shopify — Once items are “returned,” Shopify disables refunding them.
-
Use a tagging or internal note system for manual refunds, like manual-refund-needed to help track such orders.
Optional: Use an App
If manual refunds happen frequently:
. Apps like Mechanic, Order Automator, or EZ Refunds can help log, tag, and automate refund workflows or logs outside Shopify.
Thank you
