How a project runs

Four steps, and you’re in charge of every one.

The same steps for a small automation or a whole system. You always know what’s being built, what it costs and why.

  1. A free chat

    How your business runs, and what you’d love to stop doing by hand. In person around Perth or by video.

  2. A written plan and price

    What we’ll build, what it connects to and what it costs, in plain English, before any work starts.

  3. Built and tested with you

    On a practice copy, with your real work and your team. We adjust anything that doesn’t fit.

  4. It keeps improving

    We look after it, and you ask for changes in plain words whenever you like.

How we work, step by step

How we engineer it

Serious software, built properly and explained plainly.

The same care a big software house puts in, without the account managers in between. Here’s what that means in practice.

  • A written plan before any codeWhat we’ll build, what it connects to and what it costs, in plain English, agreed before anything is built.
  • Built on a practice copyEvery change is built and tested on a practice copy of your system, never on the real one.
  • Tested on your real workYour own quotes, jobs and invoices are run through it before it goes live, and you try every change first.
  • Locked to each role, all written downPeople and AI helpers only see what their role allows. Every action is recorded, and important ones can be undone.
  • Your data, kept safeKept on secure, well-known hosting, backed up, and only seen by the people who need to see it.
  • Your data and your system are yoursNever sold, never used to train anyone else’s AI. Ask for a copy whenever you like, in a format you can open.
  • The tools, in plain wordsBuilt with TypeScript, React and Next.js, widely used tools behind many of the web apps you already use. The assistant runs on Claude, by Anthropic. Works with Xero and Microsoft 365.
  • Looked after from PerthYou deal with Colin Tross, who plans it, builds it and looks after it. Ask for a change in plain words, from the screen you’re on.

Software engineering, Perth

Proper software engineering, without the jargon.

Good software engineering is mostly discipline: a clear plan, changes made on a practice copy, testing on real work, a record of who changed what, and someone who picks up when you call.

We do all of that, and we explain it in plain English. You’ll never be handed a document you need a developer to read.

  • A plan you can read, with the price in writing
  • Every change tried by you before it goes live
  • Important actions can be undone

Example: a strata manager’s plan, approved before anything is built.

Colin Tross, founder of Tross Business Automation, in Perth Perth, WA

Who you’ll deal with

You talk to the person who builds it.

Colin Tross founded Tross in Perth and plans, builds and looks after every system. Tross builds and runs its own software platform every day, and your system is built on it.

We’re small on purpose: the person who plans your software builds it and looks after it. We’re based in Perth and work with businesses right across the metro area, from the CBD and West Perth to Joondalup, Osborne Park, Midland, Fremantle, Rockingham and Mandurah, and with regional WA by video, from Bunbury and Busselton to Geraldton, Kalgoorlie and the Pilbara.

  • Plain English, no jargon
  • The plan and the price in writing before anything starts
  • In person around Perth, by video anywhere in Australia

Questions Perth owners ask

Software development in Perth: the plain answers.

What does a software project with Tross look like?
Four steps: a free chat about how your business runs, a written plan and price, building and testing it with you on your real work, and then it keeps improving as you ask for changes.
How do you test software before it goes live?
Every change is built on a practice copy of your system, never the real one. Your own quotes, jobs and invoices are run through it, and you try every change before it goes live.
What do you build with?
TypeScript, React and Next.js, widely used tools behind many of the web apps you already use. The assistant runs on Claude, by Anthropic. It works with Xero and Microsoft 365.
Will we be locked in?
Your business information is yours and you can ask for a copy whenever you like, in a format you can open. Who owns what we build, and what happens if you ever want to move on, is written into your plan before work starts.
Do you look after the software after launch?
Yes. We keep it running, fix what isn’t right, and you ask for changes in plain words from the screen you’re on. That’s the whole point: your software keeps changing with your business.
Do you work with businesses outside Perth?
Yes. In person around Perth, and by video with businesses across regional WA and the rest of Australia.
