Matching products by barcode or SKU

Updated 17 September 2026

Qantory only syncs products you have confirmed. Each sync group chooses one key to recognise the same product in every store.

Choose the key

Group → Products tab → Match products by:

KeyHow matching works
Barcode (EAN/UPC) — recommendedVariants with the same barcode in the stores are the same product. Exact matches can be confirmed automatically if you turn that on.
SKUFor catalogues without barcodes. Variants with the same SKU are the same product. Each SKU must be used only once per store, and you confirm every SKU match yourself — they are never confirmed automatically.

You can change the key only while the group has no confirmed products. To match by the other key later, create a new sync group.

Scan and confirm

  1. Choose Run product scan (or Scan again).
  2. Review the results by status and confirm the products that should sync.
StatusMeaningWhat to do
Ready to confirmThe same key is in every store, once per store.Confirm.
Missing in some storesThe key is in only part of the group.Confirm to sync it between the stores that have it (at least two).
ConflictThe key is used by more than one variant in the same store.Fix the duplicate in Shopify, then scan again.
Synced by another groupA store’s product can belong to one sync group only.Remove the store from the other group first.
No barcode / No SKUThe variant has no key, so it cannot be matched.Add it in Shopify (Edit in Shopify), then scan again.

Automatic confirmation (barcode groups)

Turn on Confirm exact barcode matches automatically and new products with the same barcode in every store are confirmed as soon as a scan or a product change finds them. Partial and conflicting matches still wait for you.

If you change a barcode or SKU in Shopify

A product stays linked only while it carries the barcode or SKU it was confirmed with. If you change or remove it in one store, Qantory unlinks that store’s product and stops syncing it (nothing is written). Scan again and confirm the product under its new value.

Confirm a barcode or SKU by hand

Under Advanced on the Products tab you can type a barcode or SKU and confirm the products that carry it. The products must have been scanned; if none is found, Qantory tells you why.
