See every featureDeltaSync keeps stock levels aligned across your Shopify stores. When inventory changes in your source store, DeltaSync updates the matching product in every connected store within seconds, matching items by SKU. Set an optional buffer to hold back safety stock on each target store.
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.
