# Sell Shirt Red and Blue  (Inventory Sync Group for different SKUs)

### Case

I have two products in my store:

| Product Name | SKU        | Inventory Quantity | Track Quantity Enabled |
| ------------ | ---------- | ------------------ | ---------------------- |
| Blue Shirt   | BLUE-SHIRT | 30                 | Yes                    |
| Red Shirt    | RED-SHIRT  | 20                 | Yes                    |

I want these two products to **share the same inventory pool** so when one sells, the stock reduces for both. This helps me avoid overselling and manage stock centrally.

### Solution: Create an Inventory Sync Group

Steps:&#x20;

1. Open the sync app > click on **Inventory Sync Groups** section on the left menu > click **New** **Inventory Sync Groups** button
2. Enter a name for the group, e.g., **Inventory Sync Group -T-shirt** and Set the group status to **Active**.
3. Set **Initial Synced Stock**  to **50** (which is the sum of 30 + 20)
4. Add the two products: **Blue Shirt** and **Red Shirt.** I filter them by tag. Click Preview variants button to see that products will be added to the group
5. **Save** the Inventory Sync Group.

   Once saved, all included products will share the same inventory: when one sells, others update automatically.

* When a customer buys **1 Blue Shirt**, the shared stock reduces from 50 to **49**.
* This updated stock is reflected for both products, so the inventory shown for Blue Shirt and Red Shirt becomes **49**.
* If a customer buys **2 Red Shirts**, the stock reduces from 49 to **47**, and this update is visible for both products.

Summarizing the inventory changes after purchases:

| Action           | Shared Stock | Blue Shirt Stock | Red Shirt Stock |
| ---------------- | ------------ | ---------------- | --------------- |
| Initial stock    | 50           | 50               | 50              |
| Buy 1 Blue Shirt | 49           | 49               | 49              |
| Buy 2 Red Shirts | 47           | 47               | 47              |
