How much does custom software cost in Australia? (2026 guide)

Ask five Australian development agencies what custom software costs and you’ll get five versions of “it depends” — usually followed by a quote starting at $50,000. That answer is true for some projects and wildly wrong for most of the software small businesses actually need.

So here are real numbers. We’re a custom software studio and these are the price bands we and comparable Australian developers work in as of 2026. Prices are in AUD and exclude GST unless noted.

The short answer

Project type	Typical cost (AUD, ex GST)	Typical timeline
Small automation or focused tool	$2,000 – $15,000	1 – 3 weeks
Internal system (portal, dashboard, booking)	$15,000 – $60,000	4 – 10 weeks
Customer-facing product / MVP	$60,000 – $150,000	3 – 6 months
Complex platform (multi-tenant, integrations, mobile)	$150,000+	6 months +

Most small businesses asking “what would it cost to fix this annoying process?” land in the first two rows — and the first row surprises people. A script that watches a folder, reads invoices with OCR and files them into Xero is a four-figure project, not a six-figure one.

What you’re actually paying for: hourly rates in Australia

Almost every quote, fixed-price or not, is built from an hourly rate multiplied by estimated effort. Current Australian market rates:

Who	Hourly rate (AUD)
Junior freelancer	$70 – $110
Senior freelancer	$110 – $180
Boutique studio (2–10 people)	$120 – $200
Mid-size agency	$180 – $280
Enterprise consultancy	$250 – $400+

Two things worth knowing about these rates:

• A higher rate is often cheaper overall. A senior developer at $160/hr who builds your tool in 30 hours costs less than a junior at $90/hr who takes 80 hours and leaves bugs behind.
• Offshore rates ($25–$60/hr) are real but rarely as cheap as they look once you add the management overhead, timezone lag, and rework. Offshore works best when you have someone technical managing the work. If you don’t, the savings frequently evaporate.

The five things that drive your price

When we scope a project, these factors move the number more than anything else:

1. Number of screens and user roles

A tool with one screen and one type of user is a fraction of the cost of one with an admin view, a staff view, and a customer view. Every role multiplies the testing surface. If you can launch with one role and add the second later, say so — it can halve the first invoice.

2. Integrations

“It just needs to talk to Xero” is sometimes a day of work (Xero’s API is excellent) and sometimes three weeks (a legacy system with no API, where the only way in is parsing emailed CSV files). Each integration adds $1,500–$10,000 depending on how cooperative the other system is. APIs like Xero, Stripe, Shopify and Google Workspace sit at the cheap end; anything where the vendor says “we can export a report” sits at the expensive end.

3. How clean your existing data is

Migrating ten years of inconsistent spreadsheet data into a new system is often 20–30% of project cost. If your data lives in one tidy spreadsheet, migration is nearly free. If it lives in 32 branch spreadsheets with different column names — a real project of ours — budget for a cleanup phase.

4. Design expectations

Internal tools used by five staff don’t need custom-designed interfaces; a clean, standard layout does the job and saves $5,000–$20,000. Customer-facing products do need real design, because customers leave when software feels broken. Be honest about which one you’re building.

5. Who’s deciding on your side

Projects with one decision-maker who responds within a day come in on budget. Projects where every screen needs sign-off from three people run 30–50% over. This is the cost factor nobody quotes for, but every developer prices in after meeting you.

Real examples (our projects)

Some context from real projects we’ve shipped:

• Invoice OCR and Xero filing — watches a folder, extracts vendor, date and total, files into the right Xero account, pings Slack. Saves the bookkeeper about 3 hours a week. Built in under three weeks; low five figures including a month of tuning.
• PDF mail merger — upload a template and a CSV, get 850 personalised investor reports per run. Mid four figures.
• Spreadsheet consolidator — merges 32 branch spreadsheets with validation and conflict reporting. Replaced a fragile Excel macro. Mid four figures.

None of these would justify a $50,000 quote, and a business that’s only ever heard “apps cost six figures” would never have asked. That’s the gap this guide exists to close.

The costs people forget to budget

The build price isn’t the whole price. Plan for:

• Hosting and services: $10–$200/month for most small systems (server, database, email delivery, file storage).
• Maintenance: dependencies need updates, certificates expire, APIs change. Budget roughly 10–20% of the build cost per year, or a small monthly retainer. We’ve written a full breakdown in our guide to ongoing maintenance costs.
• Your team’s time: testing, feedback, and writing down how the current process actually works. Cheap projects go over budget most often because nobody on the client side had time to answer questions.

How to keep the cost down (legitimately)

1. Shrink version one. The single biggest lever. Launch the one workflow that hurts most; add the rest after you’ve used it for a month. Half of “essential” features stop being essential once the core tool exists.
2. Bring a written description of the current process. An hour spent writing “here’s what Sandra does every Tuesday, step by step” saves multiple billed hours of discovery.
3. Use boring technology. If a developer proposes a novel stack “for scalability” on a 10-user internal tool, get a second quote.
4. Ask for a fixed price on a fixed scope. Reputable studios will fix-price well-defined small projects. Open-ended hourly on a vague scope is where budgets die.
5. Don’t pay for design you don’t need (see factor 4 above).

Red flags in quotes

• A precise quote produced without anyone asking you detailed questions.
• “Unlimited revisions” — it means the scope was never defined.
• No mention of who owns the code (you should — in writing).
• Hosting locked to the developer’s own servers with no exit path.
• A price that’s a third of every other quote. Someone has misunderstood the project, and you’ll pay the difference later in rework.

Frequently asked questions

Is custom software worth it for a small business? Run the maths on time saved. A tool that saves one person 3 hours a week saves roughly 150 hours a year — at $40/hr loaded cost, that’s $6,000 a year against a one-off build that might cost $5,000–$8,000. Payback inside 18 months is common; faster when the tool removes errors as well as hours.

Why do quotes for the same project vary so much? Different assumptions about scope, different seniority of the people doing the work, and different overheads. Always compare what’s included — discovery, testing, deployment, warranty period, support — not just the bottom line.

Can I get something useful for under $5,000? Yes, if the problem is narrow: one workflow, one or two users, standard integrations. Most of our portfolio started exactly there. What you can’t get for under $5,000 is a customer-facing product.

Do these prices include GST? No — add 10% for GST. Most B2B quotes in Australia are quoted ex-GST, but always check.

How long will my project take? Usually less time than people expect for small tools and more for products — see our guide on how long custom software takes. Thinking mobile? Mobile carries its own price logic — see our app development cost guide.
