Question: My products imported, but they aren’t linking/matching in ToolE. What should I check?
Answer: Linking issues are usually caused by the item not being linked at the variant level, or the identifier used for linking not matching exactly.
Quick checks (linking/matching)
The product/variant isn’t linked
If a Shopify product/variant is not linked to an Amazon FBM or FBA listing, ToolE can’t sync it.
What to do: Confirm the item appears as linked in the app (linking is done at the variant level when variants exist). If it’s missing, re-run linking / re-fetch/relink based on your setup.
Your selected linking identifier doesn’t match exactly
If you link by SKU, the SKU must match exactly between Shopify and Amazon.
Common mismatch causes
Extra spaces (e.g., ABC-123 vs ABC-123 )
Different capitalization/formatting
Variant SKUs missing or duplicated
What to do
Verify the identifier you selected for linking (SKU / Barcode / Metafield / ASIN) is populated and consistent.
If SKUs don’t match, consider linking via Barcode or Metafields (depending on your plan/workflow).
You changed fulfillment channel (FBM ↔ FBA)
Switching a product between FBM and FBA can cause the linked offer/record to change, which can make an item appear not linked temporarily.
What to do
Confirm whether the SKU is meant to be FBM, FBA, or both.
If you sell both, confirm whether you use separate SKUs for FBA vs FBM.
Allow time for the next catalog/link reconciliation, and re-link if needed.
If only some items linked
Usually, the ones that didn’t link are missing the identifier you chose (SKU/Barcode/Metafield/ASIN) or the value doesn’t match exactly.
Tip: Pick 2–3 non-linking examples and verify:
the identifier exists on the Shopify variant
it matches the Amazon side exactly
the item is intended to be FBM/FBA as configured
