To edit an Affiliate's details, go to People > Affiliates > select the Affiliate > Edit Profile and adjust their details accordingly, before clicking Submit.
Note: The Affiliates area only appears if 'Use Affiliates' is enabled via System > Settings > People and Activity > People. You can read more about enabling Affiliates here.
Adjusting an Affiliate's commission
Go to People > Affiliates > select the Affiliate > Edit Profile > Accounting. From here, you can adjust the commission percentage.
The Affiliate Accounting tab, with the commission percentage box highlighted.
The commission is calculated from the commission on the Lesson, which is the difference between the Client's Charge Rate and the Tutor's Pay Rate. You can read more about paying your Affiliates here.
Note: The Accounting tab is only editable by Administrators. If the Charge Rate on a Lesson is the same as or lower than the Pay Rate, there is no commission to calculate from, so no Affiliate payment will be generated.
