Referral IDH commissions are the same as regular IDH points earned by purchases, but are collected differently. When you make purchases yourself, IDH points are assigned at a rate of 1 point per every $10 spent (including all shipping charges). Referral commission work similarly, but do not round off at every $10. When your referred customer completes an order, both of you will receive IDH rewards. The customer receives IDH points based on the normal rate, and you - the referrer, gets the amount of IDH commission equivalent to the order total times by 10%.
