# Two-way inventory sync
### β What is Two-way Inventory Sync?
With **Two-way sync**, inventory can flow in both directions:
* If inventory changes in the **Source store** β it updates the **Destination store**
* If inventory changes in the **Destination store** β it updates the **Source store**
This helps keep stock consistent when you sell the same products in multiple stores.
***
### π― 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
β οΈ If you want only one βmasterβ store controlling inventory, use **One-way Inventory Sync** instead.
***
### π οΈ **Steps to Set Up Two-Way Inventory Sync**
1\. Open the app in **Source** store > click **Settings**
2\. In **Inventory and Orders** part > select **Two-Way Inventory Sync**
3\. Click **Save**
