What this is: a practical blueprint and solution architecture for an auto shop — missed phone bookings today, the custom booking engine that can replace them, and the month it pays for itself.
01 · The routine today
Bookings happen when someone free can answer. Mechanic is under a car → call missed. Customer calls three competitors instead. Reminder calls the day before: another 30–60 min of someone's day. Three missed bookings a week at ~€120 average ticket ≈ €1,400/mo walking away, plus reminder labor.
02 · The custom solution
A booking page with real service slots + automatic SMS/email confirmations and day-before reminders, glued to whatever calendar they already use. The €390 bot tier. Delivered as your code, in your repo — slot types, reminder texts, and calendar targets are yours to change anytime, no ticket to a vendor required.
03 · The crossover month
One recovered week covers the build; month 1 is already positive. The reminder labor disappears the day it goes live.
