No-Show

No-Show is a core concept for restaurants evaluating reservation software, guest experience, and service performance. This glossary page explains the term in practical operator language.

Definition

A no-show is a reservation where the guest does not arrive and does not cancel in time for the restaurant to resell the table.

No-Show matters because restaurant demand is perishable. Once a service period passes, empty seats, missed guest context, and unmanaged demand cannot be fully recovered.

How to measure it

  • It creates lost revenue during high-demand periods.
  • It can be reduced with reminders, cancellation links, policies, and deposits.
  • It is easier to recover when waitlist demand is connected to the reservation book.

Use cases

  • Use no-show when training hosts and managers on service goals.
  • Reference no-show when comparing reservation software workflows.
  • Track no-show alongside reservations, waitlist, CRM, and floor data.

Examples

  • It creates lost revenue during high-demand periods.
