# Update Master Inventory

### ✅ What is “Master inventory”?

The **Master product** is the bundle product your customers buy (example: **Gift Box Set**).

The **Master inventory** represents how many bundles are available to sell, based on the inventory of the **component products**.

***

### 🎯 Why you might need to “Update Master Inventory”

Normally, Tipo app updates bundle availability automatically when components change.\
But sometimes you may want to force a recalculation, for example:

* You just created or edited a Bundle Group
* You imported bundle groups via CSV
* Component inventory was updated in bulk (import/another app)
* Master availability looks out of date and you want to refresh it

***

### 🔄 What happens when you update Master inventory?

When you run **Update Master Inventory**, Tipo app will:

1. Read the latest inventory of all **components**
2. Recalculate how many bundles can be created (based on quantity rules)
3. Update the **Master product inventory** to match the calculated result

✅ This helps keep your bundle availability accurate.

***

### 🛠️ Steps

1. Open the app > go to **Bundle Groups**  > select the bundle groups you want to update by checking the boxes beside their names.
2. Click **Update Master Inventory** button

The system will automatically:

* Recalculate the **Master Product** quantities based on the current inventory levels of their **Component Products**.
* Update the **Master** **Product** stock across all linked bundles.

&#x20;**Example:**\
Suppose your Master variant (a gift set) includes:

* 2 × Product A
* 1 × Product B

If Product A now has 6 units in stock and Product B has 5, then the Master variant will be recalculated as **min(6 ÷ 2, 5 ÷ 1) = 3 units available**.

This action recalculates the master variant’s inventory based on the component inventory, following the setting **“Sync Master with Component inventory”** in the app’s settings.
