In this episode, Joshua discusses three types of referral sources: 1) Clients who refer future clients, 2) Non-Clients who refer clients, and 3) Non-Clients who refer non-clients who refer clients. The first is the most ideal but may only account for 10% of the referrals you receive. Still, it is extremely important that you leave a good impression on your clients. They may refer family members or other close friends. Give them great customer service, and you will be rewarded for it.
