Definition
Coupon attribution connects a conversion to an affiliate through a unique promotion code instead of or in addition to a tracking link. It can capture offline, podcast, newsletter and community referrals.
B2B SaaS context
SaaS merchants use coupon attribution when buyers may skip the affiliate link but still remember a partner code during checkout. It is useful with Stripe coupons, but needs rules for conflicts with click attribution.
Operator note
Make coupon ownership unique per campaign, log when a coupon overrides click attribution and prevent partners from claiming codes not assigned to them.
