How waitlists and holds turn a cancellation into a booked job within minutes.
Cancellations are capacity
A cancelled 1–3 PM window is a technician hour you already paid for. Filling it with a waitlisted no-cool customer is pure recovered revenue.
One customer at a time
The freed slot is offered to the best waitlist candidate with a short hold. If they accept, the booking is created in your FSM; if not, the next candidate is offered. No double-booking, no broadcast to everyone.
