I’m not in the industry, but as a consumer I would find this unusual as I’ve never encountered that from other similar trades. Maybe if you pitched it as a booking fee of $25 or something cheap that would be rolled into the final bill? Don’t know if that’s worth it at that point. I often do in-person consulting and bill at the time of service - I just try to do a quick pitch of why I’m better than my competitors before I get off of the phone. I just look at cancellations as part of the business model

Sounds interesting to me. Obviously depends on pricing and UI. The free plan would be a must for me to use a trial basis before signing up.
