Overbooking
Intentionally booking more appointments than available capacity, anticipating cancellations or no-shows.
Definition
Overbooking is a capacity management strategy where businesses accept more bookings than they can serve, anticipating that some percentage will cancel or not show up. Common in airlines and hotels, it's also used by busy service providers to ensure full utilization. The risk is having to turn away or reschedule clients when everyone shows up.
Overbooking
A dentist allowing 4 bookings per hour expecting 1 no-show
A salon overbooking by 10% based on historical cancellation data
A consultant accepting extra calls knowing some will reschedule
Event registration exceeding venue capacity by expected no-show rate
Why Overbooking Matters
Empty appointment slots represent lost revenue that can never be recovered. If you have 20% no-shows without overbooking, you operate at 80% capacity. Strategic overbooking can increase effective utilization to 95%+. But poor execution creates angry clients.
