Custom software in Australia is priced by the problem, not by the page count, which is why a fair quote always starts with a scoping conversation rather than a calculator. For a genuinely bespoke operations platform, customer portal, or internal system, most Australian businesses spend somewhere between A$60,000 and A$520,000 depending on how much workflow the software has to absorb and how many other systems it has to talk to.
The figures below are project totals for a senior build, not hourly rates, and they assume you own the code and the deployment at the end. A two-week paid discovery sits in front of every engagement so the number after it is fixed, not a range that drifts as the work goes on.
All figures are quoted in Australian dollars. GST is shown as a separate line on every invoice, so the band you approve in scope is the band you pay before tax, and the 10 per cent is never folded in to make a number look smaller than it is.
| Engagement | Range | What's included |
|---|---|---|
| Focused internal tool or single workflow | A$60,000–A$120,000 | One core workflow replacing a spreadsheet or a manual process: auth, a clean data model, an admin dashboard, and one or two integrations. The fastest path to owning real software instead of renting a SaaS that almost fits. |
| Operations platform or customer portal | A$120,000–A$280,000 | Multiple roles, several integrated systems, and a real permission model — the band most mid-market Australian software projects land in. Live ERP or accounting integration, document handling, and an admin console for your own team. |
| Multi-system platform with deep integration | A$280,000–A$520,000 | A platform that becomes the system of record across departments, with two-way syncs, complex business rules, and high-assurance data handling. Common in regulated and resources-sector work where the process is genuinely specific. |

Every system the software has to read from or write to — ERP, accounting, CRM, payment, or a legacy back office — adds scope. One clean modern API is cheap; a brittle SOAP endpoint or a system with no real API is where budgets stretch.
Software that treats every user the same is simple. Software that has to model dealers, vendors, internal staff, and external auditors with different views and rights carries that complexity through every screen and every query.
Bringing history across from spreadsheets or a legacy system, deduped and reconciled, is often a project inside the project. Teams will not trust software that lost their records, so getting this right is rarely optional.
Privacy Act 1988 obligations, audit trails, and data-residency requirements add real engineering, especially in finance, defence, and health-adjacent work where access control and traceability are requirements, not extras.
Custom software that replaces the spreadsheets and duct tape, shipped in quarters, not years.
