Revenue engine · not another booking app
Spare Chair sits on top of the software you already use, reads live demand, and moves your prices automatically. It fills quiet hours and protects margin at peak. You set the floor and the ceiling. The model does the rest.

How it works
Spare Chair is a layer, not a platform. You keep your booking software and your workflow. We just make the prices right.
01
two numbers
Connect and set your guardrails
You authorise Spare Chair once, then set the lowest price you will accept and the highest you want to charge. That is the only setup. No migration, no onboarding forms, no setup fee.
02
no cold start
Prices start moving on day one
We already know what your city and category look like, because we track 2,200+ providers daily. You get market-accurate prices before you have any history with us.
03
automatic from here
The model learns your business
Every slot that fills or goes empty trains the engine on your demand curve. Within weeks pricing is personalised to your chairs, your staff, your calendar, and it never steps outside your band.
Why Spare Chair
Dynamic pricing exists, but only for businesses that happen to be on the right platform. Spare Chair is the layer that works across all of them.
Platform agnostic
Zenoti prices Zenoti. Fresha prices Fresha. Spare Chair prices anything with a writable price endpoint, so the platform you chose stops deciding whether you get dynamic pricing.
Zero migration
No data export, no re-training your team, no implementation invoice. You install a layer, not a new business system.
You set guardrails, not rules
Tell us the lowest price you will accept and the highest you are comfortable charging. Inside that band the model owns every decision. No schedules, no per service logic, no weekly spreadsheet.
Vertical agnostic
Salons are the first vertical, not the limit. The engine prices any perishable appointment: studios, clinics, spas, treatment rooms.
WHAT OPERATORS SAY ABOUT THE ALTERNATIVES
“Changing pricing required going into several different places”
Zenoti review
Nothing to change. Prices move on their own.
“Onboarding involved completing a large number of individual forms”
Zenoti review
No onboarding forms. You stay where you are.
“Most expensive software out there”
Mindbody review
An add-on, not a stack replacement.
“Constantly pushing features no one wants”
Mindbody review
One job: pricing.
The data moat
A booking platform can only learn from its own customers. Spare Chair scrapes across all of them every day, so we know what a Saturday 11am blow-dry is worth in your postcode before you have taken a single booking with us.

Competitive landscape
Zenoti, Fresha and Mindbody all ship dynamic pricing, but only for their own customers. If you are on Timify, Booksy or Treatwell, none of them can help you.
