With just referring people to us, you receive 20% of all revenue brought in for that customer for the lifetime of the customer. So if a customer pays $59.99/month for 3 years, you receive $11.99/month for all those years.
The second option is to become a white label reseller of our system. With this option you pay $29.99/month to receive wholesale pricing on each of our accounts. Then you receive our software and can brand it appropriately for you. You are welcome to sell our services for whatever price you would like, and you handle billing with your customers.
