This WordPress plugin is an extension to the Affiliates plugins and WooCommerce.
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 (requires WooCommerce). 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.
To obtain the plugin go here Affiliates Permanent.
See the plugin’s documentation pages Affiliates Permanent for more details.
