# Disable Commission on Store Credit Purchases
**GoAffPro** provides you with the option to disable the commission for sales made using store credits.
To disable commission on sales made using store credits, go to the **Commission Modifiers** section in the **Commissions** tab of the GoAffPro admin panel.
Commissions > Commission modifiers
Here, click on **Add new modifier**.
Now, select the "Payment gateway matches" rule.
After this, set the "matches" value to Store Credits.
{% hint style="info" %}
You can set the value to any payment gateway for which you want to disable the commission.
For example, if you want to prevent commissions on sales made with gift cards, you can set the matching value as "**gift\_card**" which is the technical name for the gift card payment gateway in Shopify. Similarly, to prevent commissions on sales made using Shopify store credits, you can set the matching value as "**shopify\_store\_credit**"
{% endhint %}
Now, set it to "adjust commission by" -100%.
Finally, click on **Add Modifier**.
The newly set commission modifier will prevent commissions from being calculated on sales made using store credits.
