Interactive 4-screen calculator I built to use during discovery calls with med spa and cosmetic practice owners. The intake captures their actual numbers — monthly appointments, average ticket value, no-show rate, and monthly lead volume — then calculates in real time where revenue is leaking: no-show losses, unconverted leads, reactivation gap from inactive patients, and after-hours inquiries that never get a timely follow-up. The final screen shows a side-by-side Current State vs. Recovered State view with monthly gain, annual gain, and conservative 60% recovery projection. Turns abstract "lead leakage" into concrete dollar figures on screen, so the conversation is about outcomes instead of features. (Numbers in screenshots are example values for demonstration, not client results.)
