The CenturyLink Business Referral Program allows participants to earn cash rewards for referring new business customers to CenturyLink. Participants can earn a one-time payment based on the new customer's initial monthly spend if CenturyLink gains the new customer through their referral. The more businesses a participant refers, the more potential they have to earn rewards. There are no costs, sub-agent agreements, or complex processes involved - participants simply visit the program website to learn more.
