Auto-match every SKU
Connect Shopify plus your Amazon and TikTok stores with your own read-only keys. StockLock matches each marketplace listing to your Shopify catalog by barcode, then SKU, then title — no manual mapping, and never a duplicate row.
Multi-channel inventory that never oversells.
StockLock keeps Shopify, Amazon, and TikTok in sync. It auto-matches your SKUs across channels, imports your old Trunk or Syncio setup, and locks stock safely — using keys you control.
Import your old setup
Already on Trunk or Syncio? Drop your export and StockLock backfills your products, channel listings, and sync links with their relationships intact — so switching is a two-minute job, not an afternoon of spreadsheets.
Lock stock safely
Inventory is pooled off one canonical entity per real product, so a sale on any channel updates every channel. Conflicting barcodes are flagged for review, never silently merged — the failure mode that oversells.
