How much does custom software cost in Perth?

It depends on how many people use it, what it connects to and how much old information needs moving across, so we don’t publish a number. After a free chat you get a written plan and a price, before you commit to anything.

Is custom software worth it for a small business?

When off-the-shelf software almost fits and the gaps are filled by hand, often yes: the hours spent working around it add up every week. In the free chat we’ll tell you honestly if an app you can buy would do the job instead.

Who owns the software and our data?

Your business information is yours: customers, jobs, prices, documents, all of it, and you can ask for a copy whenever you like. Who owns what we build, and what happens if you ever want to move on, is written into your plan before work starts.

Can it work with Xero and Microsoft 365?

Yes. Invoices sync to Xero and come back marked paid, and it works with Outlook email and calendars, Teams and SharePoint. We check anything else you use and say so in the plan.

What happens when our business changes?

You ask for a change in plain words, from the screen you’re on. It’s built and tested on a practice copy, you try it, and it goes live when you say so.

Do you build web apps and phone apps?

Your team uses the same system in the office and on their phones: the office on a computer, the crew on the road. Everything lands on one set of records.

Custom software · Perth, WA

Custom software, built in Perth around how you work.

When off-the-shelf software almost fits, you end up bending your business around it. Tross builds custom software around your business instead: the screens your team uses, in your words and your steps, with an AI assistant built in, changed whenever you ask.

Example: an events company’s proposal, accepted online, with the day’s jobs on the crew’s phone.

When off-the-shelf almost fits

One system that does things your way.

Most Perth businesses we meet run on a patchwork: one app for quotes, another for jobs, a spreadsheet for stock and the accounts in Xero. Each one almost fits, and the gaps get filled by hand, usually at night.

Custom business software replaces the patchwork with one system built around how you already work, and keeps the apps that are worth keeping.

Replace the spreadsheets, keep what works
Your words on the screens, your steps in your order
One set of records, typed once

Example: a cleaning business quotes from its own price list, and the phone keeps up.

Web and phone apps for your team

In the office and on the road, the same system.

Your team gets the same system on a computer in the office and on their phones. The crew sees what’s next and keeps the customer in the loop; the office sees it as it happens.

Hands-free on the road, with everything read back first
The office and the phone see the same thing
No double entry at the end of the day

Example: on the way to the next job, a text to the customer, by voice.

Your own CRM

Your customers, quotes and follow-ups, the way you sell.

A customer list that knows every quote, job, invoice and message, with the follow-ups done for you. Built for how you sell, whether that’s a proposal with options or a quick quote from your price list.

Every customer’s history in one place
A follow-up drafted when a quote goes quiet
Accepted quotes turn straight into the work

Example: a proposal is sent, opened and accepted online, and the event is set up from it.

Jobs, crews, stock and invoices

The whole run, from the quote to the invoice.

For a service or trade business, that’s everything between the yes and the money: the job lands on the right person’s phone, the stock is reserved, the hours are logged and the invoice follows to Xero.

Hours from the phone, timesheets ready for payroll
Stock reserved as jobs are booked
Invoices built from the job and synced to Xero

Example: a crew member stops their timer on the job and the office timesheet fills itself.

Tools nobody sells

And the tool your business never had.

Some jobs need something you can’t buy: a floor plan maker that turns a room layout into a quote, a booking calendar your customers use themselves, inspection reports with photos. We build those into the same system, on the same records.

Example: an events company draws the room, and the tables land on the quote.

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.
