Missed visits
Count confirmed appointments that were not completed.
Measurement worksheet · no-show
Use your own baseline
A missed appointment is not automatically recoverable revenue.
Refillable slots
Estimate only openings that could realistically be filled.
Contribution
Use sales minus variable service costs, not gross ticket value.
After launch
Check the same period, booking mix and actual completed visits.
Potential contribution = missed visits × refillable share × contribution per completed service. This is a planning formula, not a result.
