Syncio currently has limited ability to support inventory location. We allow the Source store to choose ONE location to allocate stock to the Destination store. On the Destination store side, there is no ability to assign a location so we allow Shopify to set a default location.
If you have more than one inventory location, your Source store will then behave as one location with Syncio. If you select ALL LOCATIONS, it will combine all your stock and send it to the Destination Store's default location Store.
Example 1: Source store selects All Locations → Destination store products will sync/display inventory from [Location 1, Location 2, Location 3] AS A COMBINED INVENTORY.
Example 2: Source store selects Location 1 → Destination store products will sync/display inventory from [Location 1] ONLY. When a sale is made on the Destination store, Syncio will update the inventory in Location 1 and other locations will remain untouched.
