Product Alternatives

July 20, 2026

Summary

Product Alternatives let you swap a product for a closely related alternate SKU at the catalog, order line item, or fulfillment request level, to avoid delays when an item is out of stock, archived, or a customer requests a substitute.

Attach alternates to a product, then substitute at the order line item (before the fulfillment request is generated) or on the fulfillment request itself while it is unprocessed.

  • Add alternatives — Attach alternate SKUs to a product in the catalog.
  • Order line item — Replace a line item before the fulfillment request is generated.
  • Fulfillment request — Swap on the FR via Edit while it is still unprocessed.
  • History — Track replacements in Order Status History.

Timing limits

Note: Order line-item replacement is only available before the fulfillment request is generated. After that, edit the FR; once the supplier processes it, substitution is no longer possible.

What it does not update

Note: A substitution does not update the sales channel order, the channel invoice, or notify the end customer.

No automation

Note: Product Alternatives cannot currently be automated.

Save Variant required

Note: A product cannot be added as a duplicate alternative, and any change — including deleting one — requires clicking Save Variant.

Limited recent support-ticket data for this feature; the answers below come from the product documentation.

When and where can I add a Product Alternative?

At the Product Catalog, Order Line Item, and Fulfillment Request levels.

Can I substitute after the Fulfillment Request has been processed?

No. You can only substitute while the FR is unprocessed; once the supplier processes it, products can no longer be substituted.

How do I know if a product was replaced?

Track it in the Order Status History, or hover the line item title for the replacement note.

Can I automate substitutions?

Not currently — automation for Product Alternatives is not supported.
