# How to Manage Option Stock via Add-On Products

Managing inventory for your product options is crucial — especially when your options are physical items like gift boxes, accessories, or custom add-ons. Our app makes it easy to track stock levels by linking each option to a real product using the **Add-On Product** feature.

**For the detailed setup, you can refer to the instruction video here:**[ **How to Add Price to Options & Manage Stock in Shopify with Globo Product Options**](https://youtu.be/HOSsM8-9uGk?si=-ZRQjTZcAZCIXc0o)

### 🔧 Steps to Manage Stock

#### **Create Add-On Product Linked to an Option**

* Use the **auto-generated** add-on product created by our app
* Or **select an existing Shopify product** as an add-on (this syncs the product price automatically)

#### **Configure Out-of-Stock Behavior**

You can decide how an out-of-stock option will appear on the product page:

* ✅ **Show** (but disabled/grayed out)
* 🚫 **Hide**
* ❌ **Strike-through**
* 🌫 **Blur**

### 💡 Result

When a customer selects an option linked to an add-on product:

* The option appears in the cart as a separate item
* The stock of that add-on product is automatically deducted
* You get full control and visibility over the option inventory
