# Two-way inventory sync

### ✅ What is Two-way Inventory Sync?

With **Two-way sync**, inventory can flow in both directions:

* If inventory changes in the **Source store** → it updates the **Destination store**
* If inventory changes in the **Destination store** → it updates the **Source store**

This helps keep stock consistent when you sell the same products in multiple stores.

***

### 🎯 When should you use it?

Use Two-way Inventory Sync if:

* you sell the same products in multiple stores
* both stores can create sales (or stock adjustments)
* you want inventory to stay aligned automatically

⚠️ If you want only one “master” store controlling inventory, use **One-way Inventory Sync** instead.

***

### 🛠️ **Steps to Set Up Two-Way Inventory Sync**

1\. Open the app in **Source** store > click **Settings >** turn on **Sync inventory and orders**

2. Select **Two-Way Inventory Sync**

3\. Click **Save**

### ✅ How "Two-Way Inventory Sync" Works

#### ✅ What triggers a sync?

* **Sale** (order created)
* **Refund / cancellation**
* **Restock or manual adjustment**

A sync is triggered when inventory changes due to:

#### 🔗 How products are matched

**Stores**

* Source: `urbanwear-eu.myshopify.com`
* Destination: `urbanwear-us.myshopify.com`

**Product**

* Name: Slim Fit Denim Jacket
* Handle: `slim-fit-denim-jacket`

#### Scenario 1:  Sale in Destination store

**Before sale**

* Source: 50 units
* Destination: 50 units

Customer buys **5 units** in Destination.

**After sync**

* Source: ✅ 45 units
* Destination: ✅ 45 units

➡️ The decrease in Destination is reflected in Source.

***

#### Scenario 2: Restock in Source store

You restock **10 units** in Source.

**After sync**

* Source: ✅ 55 units
* Destination: ✅ 55 units

➡️ The increase in Source is reflected in Destination.&#x20;
