Websites · iPhone and Android apps · Management systems

The website, the apps and the system. Built as one.

For businesses in any industry that are tired of running on six tools and a whiteboard. Designed, built, hosted and looked after by one small company in Upminster, Essex.

What we build

Six things. Usually two or three of them together.

The website brings the work in. The app puts it in the team's pocket. The system runs the whole thing. Build them with the same people and nothing gets typed twice.

01 — Websites

Designed and coded for you, not bought as a theme.

Quick on a phone, easy to find on Google, and connected to your stock, prices or diary so it never goes stale.

  • Design, build and hosting in one place
  • Enquiries, bookings and quotes built in
  • Search engines taken seriously from day one

02 — iPhone & iPad apps

Native apps, on the App Store, in your team's pocket.

Built in Swift. Jobs, photos, documents and sign-offs from wherever your team happens to be standing.

  • Camera, photos and documents straight into the system
  • Push notifications for the things that matter
  • Same data as the web, live

03 — Android apps

Built alongside the iPhone app and kept at parity.

Written in Kotlin, so nobody on the team is on the wrong phone. Published on Google Play, or installed privately.

  • Every screen the iPhone app has
  • Runs on rugged and budget handsets
  • One set of business logic underneath

The software your team lives in all day.

Stock, jobs, customers, bookings, invoices and accounts in one place, built around how you already work rather than how a vendor thinks you should.

  • One screen for the whole business
  • Roles and permissions per person
  • Reports the owner actually reads

06 — Hosting, integrations & support

We run what we build, and keep improving it.

Hosted on infrastructure we control, connected to the tools you already use, and looked after long after launch. You get a phone number, not a ticket.

  • AWS and Cloudflare, monitored day and night
  • Xero, WhatsApp, Google, Meta, payment and finance providers
  • Fixes and improvements after launch, not just before

How it fits together

One system underneath. Every screen on top.

Website

Brings the enquiry in and drops it straight into the diary. Reads live stock, prices and availability from the system.

Apps

Put the job, the photos and the sign-off in the team's hands, on site, and write straight back to the system.

System

Holds the customers, jobs, stock and money, and talks to your accounts. A price changed once is changed everywhere.

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. Your data, your domain, your accounts. We host it and look after it. You own it.

Process

You deal with the people building it.

No account manager, no ticket queue, no offshore team. Most projects go from first visit to live in weeks, not quarters.

Step 1We come and watch

A morning in the business, seeing how a day actually runs. That becomes the brief, in plain English, and you sign it off before anything is built.

Step 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.

Step 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.

Step 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.

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.

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.
