This feature allows you to assign lifetime sales of a customer to an affiliate so that all future orders made by the connected customer will get the affiliate the commission whether the customer uses an affiliate link/coupon or not.
To connect a customer to an affiliate, go to Affiliates & Coupons > Affiliates > Connect customer. Next, you can choose to search for an existing customer or add a new customer.
After selecting a customer and the affiliate you want to connect to, click Connect. Each customer can be assigned to only one affiliate.
In the future, even if customer doesn't use an affiliate link/coupon to purchase, the system will still record that order as a referral for the connected affiliate.
