With lifetime commission enabled, once someone uses the affiliates coupon code, that customer will be linked to the affiliate forever, and ALL future purchases from that customer and will count as a referral, even if they don’t re-use the coupon code.
Even if the coupon code isn’t used, the commission and sales will still be tracked on the coupons affiliate dashboard. All future orders by that customer, even with different coupon codes, will only apply to the original coupon affiliate.
You have the option to set lifetime commission globally for all affiliate coupons, or set it individual on a per-coupon basis.
Finally, there is the option to set an expiry period (days). If you decide to set this, the “lifetime commission” features will only apply for this amount of days after the initial order, after which the affiliate user and customer will be unlinked. If the customer re-uses the coupon code, the expiry date will refresh.
Here’s a preview of the settings:
