Coverage counts what each App Store listing names. Every feature, checked off app by app, is in Shoplist.
See every featureLige SKU Sentinel scans product variants for blank SKUs, exact duplicates, case-and-spacing collisions, duplicate barcodes, and optional missing barcodes. It is read-only: it reports issues without changing products. Review affected variants with direct Shopify Admin links, dismiss or snooze known exceptions, export results to CSV, and use recurring monitoring to catch new catalog conflicts.
Keep identifier conflicts from getting lost after catalog imports. Scan exact SKU and barcode matches, focus on active products, and record why some duplicates are intentional. Later scans flag new conflicts and changes to acknowledged groups. Review product links, export findings, and compare reports. Watch adds daily checks. The app reads your catalog and never changes products or inventory.
- Find blank, duplicate, and case-or-spacing SKU conflicts
- Flag duplicate and missing barcodes without editing products
- Triage with dismiss, snooze, direct Admin links, and CSV export
- Find exact duplicate SKUs and barcodes with explicit product-status filters
- Acknowledge intentional duplicates; review again when group membership changes
