Let them book. Keep cutting.

No. They scan the code, pick a barber and a time, and leave a name and a phone number. Nothing to install and no password to forget — which is the whole point, because a customer who has to sign up first rings you instead.

No. A slot is gone the moment somebody takes it, and it does not come back. That guard sits in the database rather than in the page, so two people tapping the same slot in the same second still produce one booking — and it has tests of its own, because this is the one thing a booking app cannot get wrong.

Put them in from the counter. The walk-in entry takes a name and a time from you, for today or for a day further on, so the chair is never sold twice to somebody who booked online.

Seven days. Far enough for a regular to take next Saturday, short enough that the diary does not fill up with appointments nobody remembers making.

There is no public price list yet — Robur Booking is being priced with the first shops running it. The shape is already settled: one amount per month, no setup fee, no minimum term, cancelled at the end of any month.

On Google Cloud servers in Germany, encrypted in transit and at rest. Robur Booking processes it under GDPR — the details are in our privacy policy. From the customer it deliberately keeps only a name and a phone number and nothing else, because a booking does not need anything else.
