01About the project

The brief

Barbers and hair salons often run their bookings across phone calls, paper diaries and chat messages. We wanted one system where every salon manages its calendar, staff, services and customers, while salons on the same platform can never, under any circumstances, see each other's data.

Our approach

We built it as a multi-tenant SaaS: every record belongs to one salon, and that separation is enforced by the database itself, not just by the application. The booking rules live in a single engine that is independent of the channel; today the web panel uses it, and later a bot or WhatsApp can use the same engine. The system is still in development.

02Key features

  • 01

    Daily calendar

    The salon's day on one screen: appointments in time order with their status (planned, arrived, cancelled), and quick switching between days.

  • 02

    Double-booking check

    If a staff member already has an appointment at that time, the system warns and lists the overlapping bookings. The salon can still choose to go ahead.

  • 03

    Price and duration are locked in

    An appointment keeps the price and duration of its services as they were when it was booked. If prices change later, past appointments keep their original amount.

  • 04

    Staff, services and customers

    Manager and staff roles, services with duration and price, customer records with phone number and notes. One appointment can hold several services and be assigned to a staff member later.

  • 05

    Data kept apart per salon

    Each salon's data is separated at database level (row-level security); one salon can never reach another salon's records.

  • 06

    Secure sessions

    Short-lived sign-in keys renew themselves safely, and if a stolen session key is reused the system detects it. The platform admin who creates salons signs in through a completely separate flow.
