From Phone+ mag:
Managed services provider Whaleback Systems introduced a new referral program that pays $500 for referring new SMB customers to Whaleback’s Crystal Blue Voice Service with new customers receiving $500 off their first phone bill. There is no cap to the program; the referrer is paid for every referral that becomes an active Whaleback customer. .... Whaleback said its referral program is ideal for independent sales agents already serving the SMB or enterprise marketplace, such as commercial real estate agents, commercial equipment representatives, business services, offices administrators .... "The referral program is designed with flexibility and simplicity in mind - there are no sales quotas or sales responsibilities," said said Mark Galvin, founder, president and CEO of Whaleback Systems.
Simple enough. Are you using a referral system? I don't mean do you have one sitting there passively. I mean, do you actively use a Referral System to generate sales?
