Design, build and hosting under one roof, for businesses in any industry: dealerships, workshops, trades, retailers and service companies. Proven in the motor trade, where our own software runs a working dealership every day.
A website that brings the work in, and a system that runs it once it arrives. Built together, so they actually talk to each other. For dealerships, workshops, trades, retailers and service businesses in any industry.
Designed and coded by us, hosted properly, fast on a phone, and wired straight into your stock, prices and bookings so the site is never out of date.
Stock, jobs, customers, bookings, invoices and accounts in one place, on the web and on the phone, with AI taking the repetitive parts off your team: reading invoices, answering the same questions, chasing the paperwork.
Auto OS is our own dealer management system, and the reason JSA Group exists. It runs a working car dealership in Essex every day, from the auction lane to the customer's driveway, and it is the standard everything else we build is held to.
Auto OS is available to other dealerships today: web, iPhone and iPad, with the integrations already built for DealerKit, Auto Trader, BCA, Manheim, Xero, WhatsApp and more. See the full picture on the Auto OS site, or book a demo and we will walk you through it on a real forecourt.
Small team, close to the work, no account managers in between. You talk to the people building it.
We come and watch how the business actually runs. The whiteboard, the spreadsheet, the phone that never stops. That is the brief.
A site and a system drawn around your day, not a template with your logo on it. You see it before a line of code.
Built quickly, then used for real by your team while we watch. Whatever breaks on a busy day gets fixed before launch.
We host it, watch it and keep improving it. Software that is finished is software that is already falling behind.
James founded JSA Group in 2025 after years in motor retail, having watched a dealership run on a dozen disconnected tools and a great deal of retyping. He built Auto OS to fix that for his own sales floor. JSA Group now builds the same kind of websites and systems for other businesses, whatever they sell.
The company stays deliberately small. Fewer people, closer to the work, and a preference for building things that last over things that merely launch.
