About Substitutions: Sold Out Swap

When a variant sells out, Shopify stops the sale. Substitutions keeps it buyable and ships a backup you approved, so the order goes out instead of being lost. The app scans your catalog and uses AI-assisted matching to suggest a backup for each sold-out variant: the same item from a new production run, in another pack, or as smaller sizes that add up. Turn one on in a click. Customers pay their original price, every swapped order is tagged, and selling stops when the backup runs low.
