Why spas move to Strong OS

Your own front door, and the money behind it

Your own front door

Your clients book on your page and in your app, with your name on it. No marketplace listing the spa down the road underneath you, and no fee for a client who was already yours.

Courses that count themselves down

Sell a course of six treatments and every booking takes one off. You and your client both know how many are left, with no paper card and no debate at the desk.

A missed 90 minutes really hurts

Reminders before every appointment and a cancellation window you set, so a treatment room does not sit empty because somebody forgot.

Everything to run the diary

One place for treatments, courses and clients

A diary per therapist

Set each therapist’s hours, their time off and the treatments they do. Clients pick from the times that are genuinely free, and nobody gets double-booked.

Treatments of any length

A 20-minute top-up and a 90-minute hot stone sit on the same diary, each with its own room and its own gap for turning the room around.

Courses, packs & memberships

Sell a course of sessions, a pack or a single treatment, and set how long a course stays usable. Sessions are tracked per treatment type, so a massage course covers massage.

Payments, handled

Take card and Apple Pay online, or take payment at the desk with a QR code. Recurring memberships and one-off purchases run themselves, no invoices to chase.

Classes alongside treatments

If you run a studio as well as a treatment room, both sit on one schedule and your clients book either in the same place. No second system, no double entry.

Know your numbers

Revenue, how full the diary is, new clients and repeat rate at a glance, so you can see which treatments are working and grow with confidence.

Questions

The things spas ask us

We run classes as well as treatments. Does that work?+

Then you are the business this was built for. Treatments and classes sit on one schedule, so a small-group session and a 90-minute massage live in the same place, and your clients book both in the same app.

We use Fresha. Why would we pay for this?+

If you take one-off bookings and nothing else, Fresha does that well and it is free. Strong OS earns its keep when you sell commitment: memberships, courses of sessions, blocks paid once, and classes alongside your treatments. It runs both on one schedule, under your own name, and nobody takes a cut of a client who was already yours. If that is not your business, we will tell you so on the demo.

Is this a clinic system?+

No, and we would rather say so upfront. Strong OS runs the diary, the courses, the payments and the reminders. It does not keep clinical notes or medical records, so keep whatever you use for those.

Can each therapist have their own diary?+

Yes. Set their hours, their time off and the treatments they do, and they see their own day rather than the whole spa’s.

Do treatments of different lengths work?+

Yes. Each treatment has its own length, its own room and its own turnaround gap, so a 20-minute top-up and a 90-minute hot stone sit happily on the same diary.

Can clients book on their phone?+

Yes. Clients book, rebook and cancel in seconds, on the web or in the app.

How hard is it to switch?+

Not hard at all, and you are not the one doing it. We move your clients across with their remaining sessions and expiry dates, build your treatment list, memberships and courses, and go live on a day you pick. You are never starting from a blank page.

Is my spa’s data private?+

Completely. Every business is fully isolated, so you only ever see your own clients, treatments and bookings.
