SKU matching
How Kizing links Shopify variants to TikTok SKUs (seller SKU, then barcode, then title), what "Needs review" means and how to fix unlinked SKUs.
Every sync depends on knowing which Shopify variant is which TikTok SKU. Kizing stores one link per pair, per TikTok shop.
How matches are found
- Seller SKU. The TikTok seller SKU equals the Shopify variant SKU. Linked automatically.
- Barcode. The TikTok identifier code (GTIN, EAN, UPC or ISBN) equals the Shopify barcode. Linked automatically.
- Title. Product and option names are similar. Never linked automatically; always shown in "Needs review" with the reason.
Each match shows a chip saying how it was found: SKU, barcode, title, manual, imported or migrated.
Review the set-aside matches
- In the setup assistant (or Products later), open "Needs review".
- For each row, confirm the suggested variant, pick another, or leave it unlinked.
- Unlinked TikTok SKUs don't get stock updates, and orders for them can't import until they're linked.
Common causes of unmatched SKUs
- The variant has no SKU in Shopify. Matching falls back to barcode or title. Add a SKU in Shopify and it links exactly.
- Two Shopify variants share one SKU. Kizing lists the pair and asks which one sells on TikTok.
- Different SKU formats (for example
TOTE-SANDon Shopify,tote_sandon TikTok). Fix one side, or link by hand.
Unlinked SKUs after setup
The hourly check reports two kinds:
- Unlinked TikTok SKU: sellable on TikTok with no Shopify link. An order for it would not import. Link it before it sells.
- Unlinked Shopify variant: in Shopify, not linked to anything on TikTok. Informational; push it to TikTok if you want to sell it there. See Push products to TikTok.
