Two people, one slot, one winner
The slot is re-checked inside the same transaction that saves the booking, and duplicate submits are ignored by idempotency keys.
Four industries · One booking engine
One booking platform. Built for every service business.
Clinics, dentists, home-service teams and salons run on the same reusable engine, then look and behave like software made only for them.

A receptionist manages appointments, not billing settings.
Availability
Why is 11:20 missing? Ask the engine.
This is the specification’s own example: business 09:00 – 18:00, doctor 10:00 – 16:00, lunch 13:00 – 14:00, a 30 minute visit, 10 minutes of buffer and one existing appointment. Toggle any rule.

Every rule you switch on removes slots, and the engine only offers what is left.

Architecture
A core engine, a configuration layer, four businesses
Industries differ by configuration, not by duplicated apps. That is what makes the fifth vertical cheap.
