Appointment Book

The diary. Clients are booked into a slot, the day is laid out by time, and the front desk can see the gaps. Off leaves a walk-in-only counter, where a chair is busy now or it is free — which is exactly how a small barber shop runs.

Switch: Settings > Salon > Appointments.

Where it appears

Salon shell: Day Book and Appointments, and the New Appointment quick action. The dashboard reads who is next and what is still to come off the same rows.

Flow

flowchart TD
    A[New Appointment
client · treatments · time] --> B[(Booked)]
    B --> C[Day Book: today by time]
    C --> D[Client arrives]
    D --> E[Treatments marked done or skipped]
    E --> F[Counter: what was actually done]
    C --> G[Did not turn up
recorded as a no-show]

A booking is a plan, not a bill — a skipped treatment simply never reaches the counter.

Screens

Day Book - today laid out by time. The screen the front desk lives on, because it shows the gaps a caller can be given.
Appointments - the whole book, past and future, by status. Reschedule, cancel with a reason, mark a no-show, or send the client to the counter.
Treatments - each carries its usual duration, which is what lets the day be laid out to scale.

Switching off. Warns at save when appointments are still booked — the settings page says how many. Switching off hides the book a client expected today is written in.
