AffiliateWP Lifetime Commissions
The Lifetime Commissions add-on links a customer to an affiliate, allowing the linked affiliate to receive a commission on all future purchases by the customer.
Lifetime commissions is a huge incentive for any affiliate looking to promote your products and services. Your affiliates will work much harder to get linked to a customer, and as a result your sales will increase dramatically.
Since the affiliate and the customer are linked, the affiliate will still be awarded a commission even if the customer clears their browser cookies or uses a different computer.
