Does it perform a full store-wide sync?
SKU Stock Sync does not force-sync the whole store; it processes due groups and waiting setup work when applicable.
No. SKU Stock Sync does not perform a full store-wide inventory sync.
The app does not scan every SKU and force all matching inventory to update on demand. Instead, it processes SKU/location groups when they become due because of inventory changes or routine checks.
Warning
Manual sync does not force-sync your whole store. It processes work that is already waiting.
If there are no due groups or setup items waiting, there may be nothing for manual sync to process.
Does it create products or variants?
SKU Stock Sync does not create products or variants; it works with existing Shopify inventory, SKUs, variants, and locations.
Does it sync between locations?
SKU Stock Sync does not sync stock between locations; the same SKU at different locations is treated as separate groups.
