What does custom software development in Perth involve?
Custom software is a tool built around the way your business already works, instead of a product you bend your team to fit. Our software development in Perth covers everything from a small single-purpose tool to a multi-module system with integrations and dashboards.
The jobs it usually solves:
- Internal tools: quoting, job tracking, stock and pricing tools that replace the spreadsheet three people are scared to touch.
- Customer portals: a login where your customers request work, check progress or download documents.
- Search and catalogue systems: thousands of parts or products made searchable, with a request for quote flow.
- AI systems: assistants that answer questions from your own data, and engines that score, check or recommend, with a person signing off.
- Integrations: connecting the systems you already pay for, like your CRM, SharePoint, Teams or your Xero or MYOB file, so nobody types the same data in twice.
We build on Next.js, Supabase (Postgres), Vercel, Twilio and the Claude API. Everything runs in a browser, works on a phone and can be installed to the home screen.
How much does software development in Perth cost?
Custom business software costs from $3,500 + GST for a focused single-purpose tool up to $25,000 + GST for a full multi-module system with integrations and dashboards. Most small business projects land between $8,000 and $15,000 + GST.
| Size of build | What it looks like | Price (ex GST) |
|---|---|---|
| Focused tool | One job done well, like a quote calculator, a stock lookup or a single integration | From $3,500 |
| Typical small business system | A few connected screens, a database, staff logins and one or two integrations | $8,000 to $15,000 |
| Full system | Several modules, integrations and dashboards | Up to $25,000 |
| Managed hosting (optional) | We keep it online, backed up and updated | $50 to $150 a month |
| Maintenance retainer (optional) | Ongoing changes and new features | From $600 a month |
The price is fixed in writing after a free scoping call, before any work starts. You own what we build and there are no per-user licence fees to us, so adding ten staff doesn't add ten subscriptions. For a deeper breakdown, read our guide to custom software cost in Australia.

Should you hire a Perth developer, a big agency or an offshore team?
For software development in Perth, it depends on the size of the job and how much managing you want to do yourself. For most small and mid-sized businesses a boutique Perth builder is the simplest fit. Very large programs suit a bigger agency, and offshore teams suit buyers who can write a tight spec and manage it.
| Option | Who you deal with | Best fit | Watch for |
|---|---|---|---|
| Boutique Perth builder (like us) | The developer who builds it | Focused tools and systems of a few modules, where speed and a direct line matter | One builder has a capacity limit, so big jobs need a realistic timeline |
| Large agency | An account manager and a project team | Big programs that need many developers at once, or formal procurement | Higher overheads and more layers between you and the code |
| Offshore team | A project manager, often in another time zone | Well specified builds where the hourly rate matters most | Time zones, handover quality and code ownership. You carry more of the managing |
None of these is wrong. The real question is who will understand your business well enough to build the right thing. With Source Digital there's no outsourcing. The person on the scoping call is the person writing the code, and you have one point of contact from quote to handover.
Software we've built for mining and industrial businesses
Our biggest builds are AI and data systems for an international tier 1 mining operator, plus a parts and quoting system for a Perth mining supplier. Each one runs on real data and was checked against how the experts already do the job.
- A commercial agent in Microsoft Teams: procurement and commercial staff ask questions and get verified answers from millions of purchasing, receipt, payment and stock rows in about a minute.
- A min and max inventory engine: a deterministic engine recommending stock levels across tens of thousands of items, proven against the inventory expert's own spreadsheet.
- A tender scorer: deterministic pricing plus an AI scoring layer that quotes page-referenced evidence, calibrated against a real evaluation panel.
- Report delivery and a contract price book: engine outputs delivered into SharePoint and announced in Teams, and benchmark rates extracted from the client's contract history.
- Equipment Group: a Perth mining parts supplier with 13 PDF catalogues. We extracted 31,354 unique parts, built a custom RFQ system and published 35,268 search pages with no CMS.
The method is the same for a ten person business. Work out exactly what the expert does, build software that does it the same way, and prove it against their numbers before anyone relies on it.
How long does custom software take to build?
Most custom software development in Perth with us takes 2 to 8 weeks from the signed quote. A focused tool sits at the short end, and a system with several modules and integrations sits at the long end.
Three things move the timeline more than the code does: how many systems it connects to, how clean your data is, and how quickly someone on your side can answer questions and test. Waiting on access to an old system, or on a sample of real data, is the usual hold up.
Where it makes sense, we ship one useful piece early and add to it, so your team is using the first part while the next part is built.
How a software build works with us
- Free scoping call. You walk me through the job, the spreadsheet or the system causing the pain. I ask about the data, who uses it and what a good result looks like.
- Fixed price in writing. A plain English scope listing what's in, what's out and the price. Nothing starts until you agree to it.
- Build and check. I build it and test it against your real examples, not made up data, and you see it working before handover.
- Handover and support. Your team is shown how to use it. You own the code and the data. Hosting and a maintenance retainer are there if you want them, with no lock-in contracts.
When is off-the-shelf software the better choice?
When a product already does 90% of what you need, buy the product. Custom software is worth it when the job is specific to how you work, when you're paying for features nobody uses, or when the gap between two systems costs hours every week.
Off-the-shelf usually wins for:
- Accounting, payroll and invoicing. Xero and MYOB do these well, so we connect to them rather than replace them.
- Standard job management for a small trade business, where products like ServiceM8 and Tradify are mature.
- Anything that needs a vendor's certification or compliance support built in.
Custom wins when your process is your edge: the way you quote, schedule, price or check work. If you're not sure which side you're on, the scoping call is free and I'll tell you straight if a product you can buy does the job.
