It is crucial you have a system and a culture of referrals in your business. It should be expected they refer their friends. Also, the person who refers is more likely to stay than the people who doesn’t refer. So reward the ones that do, and keep reminding the ones that don’t. Once someone demonstrates the ability to refer - That’s who can refer more! You MUST make a BIG deal of it when they refer. I think it’s also worth mentioning the bigger the deal you make about referrals, the more you will get. Especially when you consider people are motivated far more by recognition than they are by money. You can and should use this to leverage more referrals.
