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

✅ How One-Way Inventory Sync works

When inventory changes in the Source store (sale, restock, manual adjustment), the app will:

1. Find the same product in Destination (matched by handle or SKU or barcode)
2. Apply the inventory update to the mapped Destination location
3. 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:

• Source Store: https://furniture-eu.myshopify.com

• Destination Store: https://furniture-us.myshopify.com

You are syncing a product called:

Product Name: Modern Oak Bookshelf
Handle: modern-oak-bookshelf

Store	Inventory Before	Inventory After
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.

Store	Inventory Before	Inventory After
Destination Store	15	13
Source Store	15	15 ❌

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