Appointment Booking, Reminders & No-Show Recovery
A booking system for local service businesses that catches conflicts before they happen, chases confirmations on a 48h/24h/2h schedule, and offers a cancelled or no-show slot to a waitlisted customer within the same minute — turning a missed appointment from lost revenue into recovered revenue.

The Challenge
Service businesses that book by appointment lose revenue twice on a no-show — once when the slot goes unfilled, and again because nobody finds out in time to offer it to someone else on the waitlist.
The System
We built a single n8n workflow with five coordinated triggers sharing one spreadsheet as the source of truth: booking intake with automatic conflict detection, a staged 48h/24h/2h reminder sequence that never repeats itself, reply parsing that acts on CONFIRM/CANCEL/RESCHEDULE, a nightly no-show sweep with estimated revenue lost, and an automatic waitlist offer the instant a slot frees up.
Guardrails
Conflict detection runs before a booking is saved.
Reminder state prevents duplicate messages.
Reply parsing separates confirm, cancel, and reschedule paths.
