The RankPay WHMCS module makes it incredibly easy for web hosts to sign up their hosting customers for SEO services, thus building additional reliable and recurring revenue. By featuring a promotional banner in every customer's instance of WHMCS, you'll get a targeted ad right in front of your customers when they're logged into WHMCS. When a customer signs up for our SEO services, you'll receive a notification and start earning recurring revenue as soon as their account becomes billable.
Module is recommended by RankPay. Read more on the official RankPay website
