Catch the order mistake
before it ships.
FixStack gives shoppers a tight window to fix their own orders — wrong size, wrong address, wrong quantity — before the warehouse touches it. Fewer returns, fewer tickets, fewer apologies.

between checkout and fulfilment. Long enough to catch a mistake. Short enough that nothing's shipped yet.
How it works
Three steps. No support ticket in sight.
Shopper checks out
A FixStack panel appears on the thank-you page. "Got the wrong size? You've got 10 minutes."
They fix it themselves
Swap a size, change an address, cancel outright. FixStack talks to Shopify — no emails, no call centre.
You save a return
The order gets edited or cancelled before fulfilment. You keep the margin. The shopper keeps the trust.
You set the rules
FixStack runs on your terms, not ours.
Time window
Pick 5 minutes, 10, 60 — whatever matches your fulfilment speed. Too late and the option disappears.
Fulfilment lock
The moment your warehouse starts picking, editing locks. No shipping an order that's already on a trolley.
SKU blocklists
Custom, made-to-order, final-sale — mark SKUs as off-limits and they stay that way.
Refund target
Send refunds back to the original payment method or hold as store credit. Your call, per rule.
Country locks
Enable FixStack for domestic orders, keep international on the old flow. Or the reverse.
Full audit trail
Every edit, cancellation, and Shopify response is logged. Reconcile anything, any time.
What your shopper sees
"Ordered the wrong size? You've got 8 minutes to swap it."
No jargon. No forms. No "please contact support."
Questions you'd reasonably ask
Does this touch my fulfilment flow?
No. FixStack only acts before fulfilment starts. The second an order moves to "in progress," editing is gone.
What if a shopper edits to a cheaper item?
Shopify handles the partial refund via its standard order-edit flow. FixStack just orchestrates it and logs it.
Can I switch it off for Black Friday?
One toggle. Or shrink the window to 2 minutes. Or block specific SKUs. Rules change whenever you need them to.
How do I know it's working?
The admin dashboard shows every edit session, every outcome, every saved return. No guessing.
Install it. Try it on one order.
