SKU & GTIN Doctor launched on October 14, 2026. Shoplist is watching for its first storefront installs and tracking pricing in the meantime.
Get alerted on first storefront installs, review spikes, pricing changes, and listing edits.
Find missing SKUs, invalid barcodes, and duplicate GTINs before they block your listings.
SKU & GTIN Doctor checks your catalog every morning and lists what is wrong, with the evidence: variants without a SKU, barcodes that are not valid GTINs, the same GTIN on several variants, missing or zero prices, shipped variants with no weight, and active products with no image. Review the findings in Shopify admin or export them as CSV.
Every number on this page comes from public storefront scans and the public Shopify App Store listing. If Shoplist shows SKU & GTIN Doctor on a store, it is there.
