# How does the app match products?

To sync correctly, Tipo app needs a way to identify the “same product” across stores. This is called the **matching identifier**.

### ✅ Supported matching identifiers

You can match products using:

* **Handle** (most common)
* **SKU**
* **Barcode**

### ✅ How matching works

When sync runs:

1. The app looks at the identifier you selected (example: **Handle**)
2. It finds the same identifier in the Destination store
3. If it finds a match → update existing product
4. If no match → (depending on your setting) create a new product or skip
