One laser, three specialists: booking shared equipment without double-booking it

Here is a scheduling problem that has nothing to do with people. A clinic has three practitioners and one laser. All three are free at two o'clock on Thursday. All three have a client who wants laser hair removal at two o'clock on Thursday. The calendar, which only knows about people, happily accepts all three.

Somebody finds out at ten to two.

Salons deal with this using sticky notes, a shared paper diary for "the machine", or one long-suffering receptionist who holds the whole thing in her head. Devices in SalonRadar exist so that none of those are needed.

What a device is

A device is one physical unit your salon owns and that a service cannot happen without. A laser. A pedicure chair. An LED lamp. A cryolipolysis machine. The one room with a shower. You name each unit the way your team already talks about it, so "Laser 1" and "Laser 2" and not "Candela GentleMax Pro serial ending 4471".

It is deliberately not a list of everything in the building. Scissors and towels do not need booking. A device earns its place on the list when there are fewer of them than there are people who could use them at the same time.

How it works

1. Add your units under Devices in the catalogue. A name is all it takes.
2. Tell each service what it needs. In the service editor there is a Devices section. Tick every unit the service can be performed with. If you have two lasers and either will do, tick both.
3. Carry on booking as usual. From here the calendar does the work.

When an appointment is made, SalonRadar picks a free unit from the ones that service allows and holds it for the length of the appointment. If every suitable unit is already taken at that time, the slot is not offered online at all. Your clients never see a time they cannot actually have. If a team member tries to place the booking by hand, they get a plain message that the device needed for that service is already booked.

Everyday cases

Two units, three people

A nail studio has three technicians and two pedicure chairs. Manicures need nothing special; pedicures need a chair. With both chairs listed on every pedicure service, two pedicures can run side by side and the third technician stays bookable for manicures. Nobody has to remember the rule.

A machine goes for servicing

Switch the device's "available for booking" toggle off. It stays in your catalogue with its history, and it stops being offered. If it was your only unit, the services that depend on it stop showing free times until you turn it back on. Existing appointments are not touched, so check the calendar for the days it is away.

A treatment with two halves

Some visits combine a device service and an ordinary one: a consultation and then the laser session, say. Only the service that lists a device claims one. A service with no device behaves exactly as it always has.

Repeat courses

Laser and body-contouring work is usually sold as a course. When you create a recurring booking, each visit in the series claims its device like any other appointment, so a clash six weeks from now shows up today and not on the morning.

A few honest limits

A device is either free or it is not. There is no concept yet of a machine that needs twenty minutes to cool down between clients. If yours does, the simplest answer is to add a buffer after the service itself, which keeps both the specialist and the device clear.

And a device is not a room. If your real constraint is "only one treatment room has a sink", you can still model that room as a device, and several clinics do. It works well. Just name it so your team understands what they are looking at.

Is it worth setting up?

If you have never double-booked a machine, probably not, and you can ignore the feature entirely. Services without a device are unaffected.

If you have, it takes about ten minutes: list the units, open the handful of services that depend on them, tick the boxes. The next time three people want the same laser at two o'clock on Thursday, two of them will be offered half past three.
