One appointment record from request to invoice: Requested, Confirmed, In Chair, Done, Cancelled.

A chair can never hold two appointments at the same time, whoever creates them.

The website offers only the start times that are really free for the chosen services.

Opening hours per weekday and dated closures, enforced when an appointment is confirmed.

Find a Slot: every free start time per chair for a day, booked in one click.

Stylist rota per chair; each appointment takes the stylist on duty that day.

Each service owns a service product, so invoices use your normal income accounts.

Invoice several finished appointments at once, one invoice per client.

A Today board with the stylist, the next client and today's takings per chair.

Confirmation and decline emails, a chatter on every appointment.
