Adjust An Affiliate's Commission
Sometimes you need to adjust an affiliate's commission (for example, when an order is cancelled or returned) In order to do this, you'll need to create a manual credit for the affiliate.
Luckily, it's pretty straightforward:
In the Manage > Affiliates section click on the affiliate that you want to adjust commission for:
In the navigation bar on the left, click on Manual Credit:
Enter the amount you wish to increase or decrease the affiliate's commission by. For example, if you want to decrease it by $10 you would enter -10 or if you want to increase it by $10 you would enter 10.
Remember to click Process in order to save!
