Custom software in Australia typically costs between $30,000 and $600,000 in 2026 when built by a local team. A small internal tool or single-purpose web application starts at around $30,000, a mid-complexity system such as a custom CRM or client portal runs $80,000 to $250,000, and enterprise platforms cost $250,000 to $600,000 or more.
"How much will it cost?" is the first question every client asks, and the one most agencies avoid answering. "It depends" or "somewhere between $10,000 and $1,000,000" won't help you set a budget, write a business case or compare quotes. Neither will get you past your finance manager.
This guide gives you the real numbers: cost by project tier and software type, what pushes the price up or down, what to budget after launch, whether the R&D Tax Incentive can claw some of it back, and how to compare agency quotes without getting burned.
We're Hatchet, a Perth-based software development agency. We've spent 10 years building the custom software Australian businesses run on, and we'd rather you had the numbers now than found them out at proposal stage.
How much does custom software cost in Australia in 2026?
Custom software built by an Australian team falls into four budget bands, from $30,000 for a small application to $1,500,000 or more for a large enterprise platform. Where your project sits depends on how much it does, how many systems it connects to and how many types of user it serves.
These ranges are based on the projects Hatchet has quoted and delivered for Australian businesses over 10 years, and are current as of 2026.
Tier 1: $30,000–$80,000 (small applications)
Timeline: 8 to 14 weeks. Typical projects:
- Simple booking or scheduling systems
- Basic integrations with one to three third-party services
- A minimum viable product (MVP): the smallest version of a product you can put in front of real users
Tier 2: $80,000–$250,000 (mid-complexity systems)
Timeline: 16 to 30 weeks. Typical projects:
- Custom CRM or client management platforms
- Multi-user portals with role-based permissions
- Workflow automation that replaces manual processes
- E-commerce with custom business logic
- Applications with four to eight third-party integrations
Tier 3: $250,000–$600,000+ (enterprise platforms)
Timeline: 6 to 18 months. Typical projects:
- Full SaaS products with subscription billing
- Multi-tenant applications (one system serving many separate customer organisations)
- Systems handling sensitive data with compliance obligations
- Platforms with real-time processing, advanced reporting or AI components
- Large data migrations from legacy systems
Tier 4: $600,000–$1,500,000+ (large-scale enterprise)
Timeline: 12 to 24 months or more. Typical projects:
- Organisation-wide digital transformation platforms
- Custom ERP systems replacing SAP, Oracle or legacy platforms
- Multi-product ecosystems with shared infrastructure
- Government or regulated-industry platforms with extensive compliance requirements
These ranges assume an Australian team. Offshore rates are lower per hour, and we cover the trade-offs further down.
What changes the cost most?
Two $200,000 projects can look nothing alike. These are the variables that move the price the most.
Scope and complexity
This is the biggest lever. A booking system for one location is a different project from one that handles multi-location scheduling across time zones with automated notifications, payments, waitlists and staff rostering. Same category, very different build. Pinning this down before anyone quotes is the whole job of our Design Phase.
Number of integrations
Every third-party connection adds work. Connecting to Xero for accounting is straightforward (we're a Xero Development Partner, so we've done it many times). Adding Stripe for payments, Twilio for SMS, a CRM, an email platform and a shipping provider means more API work, more edge cases and more testing. Each integration typically adds $5,000 to $20,000, depending on the quality of the API and how much data mapping is involved.
User roles and permissions
A system with one type of user is simpler to build, test and maintain. Add admin users, staff, a client portal, partner access and public pages, each with its own permissions, dashboards and workflows, and the complexity compounds. Each extra user role adds roughly 15 to 25% to front-end and back-end effort.
Data migration
Moving data out of spreadsheets, a legacy database or another SaaS platform means mapping, cleaning, validating and testing it before go-live. Expect $5,000 to $50,000 or more, depending on the volume, quality and source system.
Compliance and security requirements
Health records, financial data, personal information or a regulated industry all bring extra security controls, audit trails, encryption and testing obligations. This typically adds 15 to 30% to the total project cost.
What does custom software cost by project type?
The table below shows typical budget ranges for the kinds of systems we're asked to build most often.
| Software Type | Budget Range | Key Variables |
|---|---|---|
| Internal dashboard / reporting tool | $30,000–$60,000 | Data sources, visualisation complexity |
| Booking / scheduling system | $40,000–$120,000 | Multi-location, payments, notifications |
| Custom CRM | $60,000–$200,000 | User roles, automations, integrations |
| Client / partner portal | $50,000–$150,000 | Permissions, document management, comms |
| Volunteer / membership management | $60,000–$180,000 | Workflows, subdomain portals, reporting |
| E-commerce (custom logic) | $80,000–$250,000 | Product types, payment gateways, fulfilment |
| SaaS product (MVP) | $80,000–$200,000 | Multi-tenancy, billing, onboarding |
| SaaS product (full) | $200,000–$600,000+ | Feature depth, scale, analytics |
| Custom ERP replacement | $300,000–$1,200,000+ | Modules, migration, training |
| Government / compliance platform | $200,000–$800,000+ | Audit requirements, accessibility, security |
Does a faster timeline cost more?
Yes. Compressing a timeline means a bigger team working in parallel, and more people means more coordination. A project that takes 16 weeks with three developers might take 10 weeks with five, and cost around 30% more.
Phased delivery is usually the smarter buy. Build a first phase that delivers the core value, put it in front of real users, then extend it based on what they do with it. It usually costs less overall, because you stop paying for features nobody uses.
Is offshore development cheaper?
Per hour, yes. Offshore development typically costs 40 to 60% less than local rates, and it would be dishonest to pretend otherwise. The total cost is a different question.
The pattern we see most often: a business engages an offshore team at $50 an hour, the project runs to three times the estimated hours through miscommunication and rework, and the final bill matches or exceeds a local quote, with a weaker result.
Perth-based senior developers typically bill $150 to $250 an hour. Sydney and Melbourne rates run 20 to 30% higher. That money buys the same time zone, direct contact with the people writing your code, Australian legal jurisdiction and someone accountable you can sit across a table from. Hatchet's team is Perth-based and has never been offshored. For more on choosing a local partner, read our guide to software development in Perth.
What does custom software cost after launch?
The build is not the whole bill. Plan for these ongoing costs:
- Hosting and infrastructure: $100 to $2,000 a month, depending on traffic, storage and compute
- Maintenance and support: 15 to 20% of the initial build cost each year
- Changes and new features: even $2,000 to $5,000 a month keeps the software improving
- Training and documentation: $3,000 to $10,000 for the initial setup
Can the R&D Tax Incentive reduce the cost of custom software?
Yes, for some projects. The Research and Development Tax Incentive (R&DTI) is a federal program, run jointly by the Department of Industry, Science and Resources (AusIndustry) and the ATO, that gives Australian companies a tax offset on eligible experimental development. If your build involves genuine technical uncertainty, part of what you pay a developer can count towards it.
The rates for the 2025-26 and 2026-27 income years:
- Aggregated turnover under $20 million: a refundable offset of your company tax rate plus 18.5%, which is 43.5% for most small companies. If you are in a tax loss, it is paid to you as cash.
- Turnover of $20 million or more: a non-refundable offset of your company tax rate plus 8.5% (R&D spend up to 2% of total expenditure) or 16.5% (above 2%), so 38.5% or 46.5% at the 30% rate.
- Minimum spend: $20,000 of eligible R&D expenditure in the income year.
Because the same spend would normally be a plain deduction at your tax rate, the real gain is the premium: 18.5 cents per eligible dollar for a small company, plus the cash-flow benefit of a refund instead of a carried-forward loss. On a $150,000 build where $90,000 is eligible, that is a refundable offset of about $39,000, roughly $16,500 of which is money you would not otherwise get back.
The catch is eligibility. Only core R&D activities qualify: experiments where a competent professional cannot know the outcome in advance, run to generate new knowledge, plus supporting activities directly related to them. Rebuilding a known workflow with known technology is not R&D, however custom it is. And software built mainly for your own internal administration is specifically excluded from being a core R&D activity, which rules out a lot of internal tools and dashboards.
Two rules matter when you are choosing a developer. The work generally has to be done in Australia (overseas work needs an Overseas Finding approved before the income year ends), and you can only claim activities conducted for your company, so you carry the risk and own the results. A local team working to an agreed scope ticks both boxes. An offshore team usually does not.
Register your activities with AusIndustry within 10 months of the end of your income year (30 April for a 30 June year-end), then claim through the R&D schedule in your company tax return. It is a self-assessment scheme, so registration does not confirm eligibility and the ATO can review claims later. Keep records from day one: the hypothesis, what you tried, what failed and why. Tell your developer at the start that you intend to claim, so tickets, test results and technical decisions are recorded with that in mind.
Hatchet is a software agency, not a tax adviser. Use these numbers to size the opportunity, then confirm it with your accountant or a registered R&D tax consultant before you build it into a budget.
How do you compare custom software quotes?
Headline numbers are the least useful part of a quote. Compare these instead:
- What's included: design, testing, documentation and project management, or development only?
- Who's doing the work: senior developers, or juniors with a senior signing off?
- What happens after launch: support terms, response times and hosting
- How they communicate during quoting: if it's slow or vague now, it won't improve once you've signed
- How long their clients stay: repeat work is the strongest signal of quality an agency can show you
The quotes that compare cleanly are the ones written against an agreed scope. That is what our Design Phase is for: a fixed-fee stage that ends with a clickable prototype, a requirements document and a costed proposal you can put next to anyone else's.
When is custom software the wrong investment?
Being transparent about cost also means being honest about when you shouldn't build. Custom software is the wrong call if:
- Your process isn't defined yet. Map it on paper first; software can't automate a process nobody has agreed on.
- An existing tool does 90% of the job. The last 10% rarely justifies a $100,000 build.
- There's no budget for ongoing maintenance. Custom software is not a one-off purchase.
- The problem is people or process, not technology. Code makes a broken process faster, not better.
