If the affiliate commission seems not to be the right one, it may be that there is a rule that is overriding the rate settings. So, make sure you check all the available settings. Consider that you can set up:
- A global rate from the Commissions & Payments page
- product and user rules from the Rates tab
- a custom rate in the affiliate’s profile
- categories and product exclusions from the General options tab.
Please, refer to this page for more details about the rules and how their priority works.
