What this is: a practical blueprint and solution architecture for a private practice — revenue lost to no-shows today, the automated reminder and waitlist system that can replace them, and the crossover week.
01 · The routine today
Front desk calls to remind, when it remembers: 12% of slots go unused. At ~€70 per empty slot and ~200 slots/mo, no-shows cost €1,700/mo — the biggest number in this series, and the most common one.
02 · The custom solution
A reminder automation on top of the existing calendar: SMS 48h and 2h before, one-tap confirm, automatic waitlist offer when someone cancels. The €390 bot tier. Delivered as your code, in your repo — reminder wording, timings, and waitlist rules are yours to tune anytime, not a settings page someone else controls.
03 · The crossover month
Halving no-shows pays for the build in the first week of any month. This is the highest-leverage build in the series.
