Commission rates on affiliate orders are calculated based on a couple of factors. 


Set Commission Rates


Within your shop settings, you can set the default commission rate that affiliates will earn on each conversion. Whenever an affiliate registers with you, they will be assigned that commission rate until it is changed for that affiliate manually.  Commission rates are based on the subtotal of each order (see examples below).


Discount Codes


Discount codes, however, take precedence to any referral and have their own commission rate assigned to them. Basically, this means that if someone uses a referral link and a discount code, the discount code will take precedence commission-wise.  The affiliate will NOT receive twice the commission.  This is to give you better control over the max payout on a sale. 




Example 1:

An affiliate has a 10% commission normally, but also has a discount code that gives the customer 10% off while the affiliate still earns 10% commission from the discount code.


A customer places an order for $10.00 before taxes, shipping, etc.  Commission from a referral link would earn $1.00 based on the 10% commission assigned to them.  If the customer used the discount code for 10% off, the $10.00 subtotal would change to a $9.00 order, so the 10% commission earned would then change to $.90 for the affiliate.




Example 2:

An affiliate has a 20% commission normally, but also has a discount code that gives the customer 10% off while the affiliate earns 10% commission from the discount code.


A customer places an order for $10.00 before taxes, shipping, etc.  Commission from a referral link would earn $2.00 based on the 20% commission assigned to them.  If the customer used the discount code for the 10% off, the $10.00 subtotal would change to $9.00, so the 10% commission would then change to $.90 for the affiliate.
