I have been allowing my group clients to “pay as they come” as opposed to a full pre-payment for, say, a month long, three-times-a week boot camp. I only make money if they show up. I’m considering cancelling that policy altogether.
Accountablility goes a long way: Paying in advance with an end date makes all the difference in the world
All of my clients pay for 10 sessions of Personal Training in advance: My bootcampers pay for 6 weeks at a time: In Advance!
