You do not! I ask my coaching clients to give the coaching program 90 days. That gives them a chance to see if we are a mutual fit and calculate the positive ROI from the early results they are getting. For that, I ask that new clients pay upfront for three months of coaching. But after that, we go month-to-month. If for whatever reason you want to stop coaching, you simply stop (or pause) and there are no hard feelings about being held to a long-term contract.
