You connect each channel with your own API credentials — a Shopify Custom App token plus your Amazon SP-API, Walmart and WooCommerce keys. StockLock asks only for read-only access to your catalog and stock, uses the keys you control, and you can revoke them in each platform at any time; nothing runs through a shared reseller account.
Match every listing into one canonical entity today — the accurate count the oversell lock is built on.
StockLock matches every marketplace listing to your catalog by barcode first, then SKU, then a fuzzy title match — so channels line up automatically, with no manual mapping spreadsheet.
Each real product resolves to a single canonical entity across Shopify, Amazon, Walmart and WooCommerce, giving you one accurate stock count to reason about instead of duplicate rows drifting out of sync.
Already on Trunk or Syncio? Drop your export and StockLock backfills your products, channel listings and sync links with their relationships intact — switching is a paste, not an afternoon of re-mapping.
The last engine: once your catalog is matched, StockLock writes the shared count back to every channel after each sale, so no listing keeps trading on a stale number. The lock algorithm is built and being wired in — connect, scan, match and import work today.
A title-only near-match never auto-links, and two listings claiming the same barcode raise a conflict instead of a silent merge — because a bad merge is the exact failure mode that oversells. Everything uncertain waits for your review.
Connect with your own read-only marketplace credentials, revocable any time. StockLock runs on Sico Software's own hardware and never sees payment details — those stay with each marketplace.
Connect your channels, auto-match your SKUs — then lock the pool (coming).
Add Shopify, Amazon, Walmart and WooCommerce with your own read-only API keys. No reseller account, no store-wide write access you didn't ask for — the credentials stay yours and revocable.
StockLock resolves every listing to one canonical product by barcode, then SKU, then fuzzy title — and a title-only near-match is held for review, never merged on a guess. Import a Trunk or Syncio export and your existing links come across intact.
Once your catalog is matched, StockLock writes the shared count back to every channel after each sale, so nothing keeps selling on a stale number. This is the final engine we're wiring in before general availability; join the beta to be set up and ready the moment it lands.
Today you can connect Shopify, Amazon, Walmart and WooCommerce, scan and auto-match your catalog into one canonical product, and import a Trunk or Syncio setup. The automatic stock-lock write-back — pushing the shared count back to every channel — is the last engine we're wiring in before general availability. Join the beta to get your channels and matching set up now; we'll switch the live lock on for your account the moment it ships.
StockLock is in private beta. Here's exactly where the product is, no rounding up.
The automatic stock-lock write-back is the one piece not live yet — the engine is built and being wired in. No billing until it works.
It resolves each marketplace listing to a single canonical product using a three-pass match: barcode (GTIN/UPC/EAN) first, then SKU, then a fuzzy title match for anything that slips through. A title-only near-match is never auto-linked — it's held for your review. Everything confident folds into one canonical entity per real product, so Shopify, Amazon, Walmart and WooCommerce all point at the same stock count with no duplicate rows.
Overselling happens when each channel trusts its own stale count. StockLock's answer is one canonical entity per product with a single accurate count, plus a stock-lock engine that writes that count back to every channel after each sale. The connect, scan, matching and canonical count all work today; the automatic write-back is the final engine we're wiring in before general availability, so StockLock does not push counts back to your channels yet. Conflicting barcodes are always flagged for your review instead of silently merged — the exact case that otherwise oversells.
Yes — this works today. Export your data from Trunk or Syncio and StockLock backfills your products, channel listings and existing sync links with their relationships intact, so you're not re-mapping everything by hand. Migrating off your current tool is a paste, not a rebuild.
Shopify, Amazon (SP-API), Walmart and WooCommerce today, connected with your own read-only API credentials (BYOK). eBay, Etsy and TikTok Shop connect are on the way. You create the keys in each platform, StockLock uses only those, and you can revoke them at any time — nothing runs through a shared reseller account.
