How It Works

The order keeps moving when stock runs out

Out-of-stock at fulfillment is one of the most expensive moments in DTC — cancellations kill the order, partial fulfillment frustrates the customer, and refund flows tie up your team. Item substitution turns that moment into a simple swap.

Triggered at fulfillment
Substitution fires when picking or inventory check discovers a SKU isn't actually on the shelf. The cart-stage flow is unaffected — substitution only kicks in once you're about to fulfill.
Native Shopify order-edit
Substitution uses Shopify's order-edit API, so the customer's order record stays accurate. No manual cancellation, no separate replacement order, no reconciliation headache.
Configurable substitution rules
You define what swaps for what — a specific SKU pair, a tier within a collection, or fallbacks across multiple alternatives. The fulfillment side picks the right replacement based on your rules.
Customer notification
Configure how (or whether) the customer is notified about the swap. Some merchants want a heads-up email, others want it silent if the swap is comparable. You decide.
Pairs with inventory confirmation
Getcho's inventory confirmation flow verifies stock before fulfillment leaves. If a SKU isn't there, item substitution applies automatically based on your rules — instead of dead-ending the order.
Shopify-only capability
Item substitution at fulfillment is currently Shopify-only because it relies on Shopify's order-edit API. Other platforms are not supported today.

Item Substitution FAQ

Common questions about Shopify item substitution

Can't find what you're looking for? Reach out to us.

What is item substitution on Shopify?
Item substitution is a Getcho capability for Shopify merchants that swaps an out-of-stock SKU for a comparable item at the fulfillment step — instead of cancelling or partially fulfilling the order. The swap is applied via Shopify's order-edit API so the order record stays accurate.
When does substitution happen?
At fulfillment — when the picking team or inventory check discovers a SKU isn't actually available. Rather than cancel the line, Getcho applies the configured substitute, edits the Shopify order, and the delivery proceeds.
Is substitution available outside Shopify?
Item substitution at fulfillment is currently a Shopify-only capability because it relies on Shopify's order-edit API. Other platforms are not supported today.
Does the customer know an item was swapped?
Yes. The Shopify order is edited so the customer's order record reflects what they actually received, and you can configure customer notifications to communicate the swap.
How is the substitute SKU chosen?
You configure substitution rules — what swaps for what — as part of your Shopify catalog setup with Getcho. Talk to our team to scope the right substitution rules for your inventory.
Does substitution affect the original payment?
Substitution uses Shopify's native order-edit flow, which handles any pricing differences according to your store's Shopify configuration. Refunds, charges, or no-change scenarios all flow through Shopify the same way they would for any other order edit.
How does this work with the inventory confirmation flow?
Getcho's inventory confirmation flow verifies stock at the picking store before fulfillment leaves. If stock isn't there, item substitution can apply automatically based on your configured rules — keeping the order moving instead of dead-ending it.
