This tool is useful if you want to grant commissions to affiliates on all purchases made by customers they refer. The affiliate will be credited with a referral on every purchase made by the customer.
New customers (or new users) are assigned to the referring affiliate. The affiliate will be credited with a referral on every purchase made by the customer from thereon. Assignments can be changed manually in user profiles.
Purchases made by existing customers who are not assigned to an affiliate will not credit any affiliate, even if the customer has visited an affiliate link after her or his initial purchase.
The normal affiliate referral process can be applied for purchases made by guests.
See the plugin’s documentation pages Affiliates Permanent for more details.
