# Special product commission
The **Special product commission** function allows merchants to set a special commission rule for each specific product or for all items in a collection. When an affiliate refers someone to purchase a product with a **special commission rate**, he/she would get the commission based on the **special rate** instead of the regular program's commission rate.
This feature is useful for products with higher/lower prices or higher/lower profit margins. Merchants can also make use of it for products they want to drive sales by offering a higher commission rate to affiliates.

**Note: ****UpPromote** triggers the Special product commission based on Shopify's product **variant ID**.
{% endhint %}
## **How to set up?**
To set a special product commission, go to **Programs** >Edit program (click on the program name) > **Special product commission > Manage.**
Programs >Edit program > Special product commission
To add a product commission, click **Add product commission**.
Programs > Edit program > Special product commission > Manage
Choose to add product(s) separately or add a whole collection:
Click the Product (or Collection if you chose to add collections) box and a list of suggested items will show up.
Choose the item, select the commission type and enter an **Amount/Rate**, then click **Add.**

**Note:** In case you edit product(s) such as add more variants or add more products to a collection on your Shopify admin, please remember to click on the "Re-sync product" button as in the screenshot below.
{% endhint %}
## How will the product commission be calculated?
If a customer's order contains a product that is set with a specific commission, the special commission rate will be applied for that product while other product commissions will still be based on the default commission of the program.
**Example**:
* Product A ($20) has a special 10% commission
* Product B ($100) is not a special product
* The program commission is 5%
The customer places an order of one product A and one product B.
\=> Commission = ($20 x 10%) + ($100 x 5%) = $7
{% hint style="warning" %}
**Note**: If your program commission is **Flat rate per order**, when you add a product with a special commission, any order containing that product will generate a double commission (commission for the whole order will be calculated based on the **program setting** plus **commission for** **the special product**)
