02 — How it fits together

One system underneath. Every screen on top.

Most businesses we meet run on a website from one company, a booking tool from another, a spreadsheet, a WhatsApp group and someone retyping it all into the accounts on a Friday. We build it as one thing.

The websiteBrings the enquiry in and drops it straight into the diary.

Stock, prices and availability are read live from the system, so the site is never out of date and nobody updates it by hand.

The appsPut the job, the photos and the sign-off in the team's hands.

A job booked at the desk is on the engineer's phone before they've finished their tea. Photos and documents go straight back into the record.

The systemHolds the customers, the jobs, the stock and the money.

A price changed once is changed everywhere. The invoice lands in Xero without anyone touching it. Your data, your domain, your accounts. We host it. You own it.

03 — Process

From first visit to live, in weeks.

You deal with the people building it. No account manager, no ticket queue, no offshore team.

  1. 1We come and watch

    A morning in the business, seeing how a day actually runs. The whiteboard, the spreadsheet, the phone that never stops. That becomes the brief, in plain English, and you sign it off before anything is built.

  2. 2You see it before it's built

    Screens drawn around your day, not a template with your logo on it. You react, we change them, nobody has written a line of code yet.

  3. 3Built, then used for real

    Your team runs live work through it while we watch. Whatever breaks on a busy Saturday gets fixed before launch, not after.

  4. 4Hosted and improved by us

    We run it, monitor it and keep adding to it. The best parts of our own software were added after it went live, because that's when you find out what a business really needs.

04 — About JSA Group

A small company, on purpose.

Upminster, EssexWorking across the UK
Since 2025JSA Group Ltd, no. 16494212
Web · iOS · AndroidPlus the systems behind them
IndependentOwner-run, no investors

JSA Group came out of motor retail, watching a good business run on a dozen disconnected tools and an enormous amount of retyping. We built the system, the website and the phone apps to run it properly, and they've run a busy dealership every day since.

Now we do the same for other businesses, whatever they sell. The company stays deliberately small: you get a direct number, the people you meet are the people who build it, and someone picks up when something needs changing at 7pm.

In the motor trade? The dealer system we built is available to other dealerships as Auto OS.
05 — Contact

Tell us what the business does.

And what's slowing it down. Every message is read by the people who build the work, and answered the same working day, usually with a couple of questions and a time to come and see you.

No newsletters, no lists. It goes to the people who build the work and nobody else.
Got it. Thank you.

We will be in touch, usually the same working day.
