# Bundle Groups Overview

### ℹ️ What is a Bundle Group?

A **Bundle Group** links a **Master product (bundle)** with one or more **Component products**.\
When inventory changes (for example, a bundle is sold or components are restocked), Tipo app updates inventory based on your bundle rules.

***

### ℹ️ When should I use Bundle Groups?

Use Bundle Groups if you sell:

* **Kits / bundles** (e.g., “Gift Set” contains 1 candle + 1 box)
* **Packs** (e.g., “3-Pack Socks” consumes 3 units of the same SKU)
* **Build-your-own sets** where the master item depends on components

***

### 🔑 Key terms

*  **Master product**: the bundle listing customers buy (e.g., “Gift Box Set”)
* **Component products**: the items inside the bundle (e.g., “Candle”, “Box”)
* **Quantity rule**: how many units of each component are required for 1 bundle

***

### ✅ How Bundle inventory works

Tipo keeps inventory accurate by:

* Reducing component inventory when the **Master** sells
* Updating Master availability based on **component stock**
* Preventing overselling when a component is out of stock (depending on your rule setup)

***

### 🧪 Example

Let’s say you sell a bundle:

**Master (Bundle):** Gift Box Set\
**Components:**

* Candle (needs **1**)
* Gift Box (needs **1**)

**Inventory before sale**

* Candle: 20
* Gift Box: 12\
  ✅ Bundle can be sold **12** times (limited by the lowest component)

**After 2 bundle sales**

* Candle becomes 18
* Gift Box becomes 10\
  ✅ Bundle availability becomes **10**

***

### ℹ️ What affects syncing?

Bundle updates can happen when:

*  An order is created (bundle sold)
* An order is refunded/cancelled (inventory returned)
* You edit the Bundle Group settings/rules
