One-Way Inventory Sync
One-Way Inventory Sync keeps inventory updated in one direction only:
Source store controls inventory → Destination store follows
This is the safest option if you want one “master” store to manage stock.
✅ When should you use One-Way Sync?
Use this mode if:
you manage inventory in one main store (Source)
you want Destination stores to always match Source stock
you don’t want Destination store sales/adjustments to change Source inventory
⚙️ Steps to Set Up One-Way Inventory Sync
In Source store
1. Open the app in Source store > click Settings > Enable Share product setting
2. In Inventory and Orders part, select One-Way Inventory Sync
3. Click Save
✅ How One-Way Inventory Sync works
When inventory changes in the Source store (sale, restock, manual adjustment), the app will:
Find the same product in Destination (matched by handle or SKU or barcode)
Apply the inventory update to the mapped Destination location
Update inventory in Destination to match Source
⇒ Destination can receive updates ⇒ Destination changes do not update Source
🧪 Example: Source updates Destination
One-Way Inventory Sync (Based on Product Handle)
Let’s say you have two Shopify stores connected:
You are syncing a product called:
Product Name: Modern Oak Bookshelf
Handle: modern-oak-bookshelf
Source Store
20
15
Destination Store
20
15 ✅
When someone buys 5 units in the Source Store, the inventory in the Destination Store is automatically updated to match (15 left).
✅ This works because both products have the same handle: modern-oak-bookshelf.
What Happens if Inventory Changes in the Destination Store?
Let’s say a customer buys 2 units from the Destination Store.

In One-Way Sync, the Source Store is not affected. Inventory changes in the Destination Store do not sync back.
