How it sells itself

Selling your last unit twice turns one order into a refund and an apology. StockUnison keeps one stock count wherever that item sells. Sync two-way: every product with the same SKU shares one count, in one store or many, and each location you share keeps its own. Or sync one-way: one main store in charge, every connected store copies it. 100,000 variants are matched in about a minute.

Syncsafe keeps inventory in sync between two Shopify stores, one way, matched by SKU. What makes it different is what it refuses to do. Every stock change goes through a validation gate before anything is written: it checks the SKU resolves to exactly one variant in the other store, that the result is not negative, and that the change is not big enough to look like a mistake.

Key points
  • Match products across stores by SKU, with duplicates and gaps flagged
  • Push stock changes from one source store to every connected store
  • Preview every change in dry run before any inventory is written
  • Check for drift at any time and reconcile stores back into agreement
  • Every stock change is checked before anything is written to the other store
  • Refuses writes that would zero or wreck your stock, and tells you why
  • Matches variants by SKU, and flags duplicates instead of guessing
  • A permanent record of every stock change and why it was or was not written
