The bands

What projects cost, in plain numbers.

Web applications

2–5 weeks

AUD 15,000 – 60,000

Portals, dashboards, internal tools and client apps. The most common build in the country — and in our studio.

Web app development

Mobile applications

4–8 weeks

AUD 20,000 – 80,000

iOS and Android from one codebase. Higher than web because of store submission, device testing and offline work.

Mobile app development

Backend & APIs

2–6 weeks

AUD 10,000 – 50,000

APIs, databases and integrations. Complexity of data and uptime needs drive this more than screen count.

Backend & API development

AI integrations

2–4 weeks

AUD 5,000 – 30,000

Document pipelines, agents and copilots. Narrowest scope, fastest payback.

AI integration

Spreadsheet replacements

2–5 weeks

AUD 10,000 – 40,000

Includes migrating your existing data out of the sheets — nothing gets re-typed by your team.

Spreadsheets to software

Internal tools

2–5 weeks

AUD 10,000 – 50,000

Quoting, approvals, job management, dashboards — built around your process, owned by you.

Internal tools
What moves the number

Screens are cheap. Integrations are not.

Three things dominate the quote. First, how much data the system owns — and how carefully it must protect it. Second, how many existing systems it has to live beside: Xero, MYOB, CRMs, payment providers, legacy software with an uncooperative API. Third, how strict your rules are — approvals, compliance, role-based access, audit trails.

The mistakes that blow up budgets: vague scope (“we want an app”), per-platform builds, changes discovered at the end, and finding out the “simple” integration is a weekend of work. Our quotes declare scope, timeline and assumptions in writing — and we champion the assumptions loudly so they get tested early.

Our pricing discipline

Fixed price, in writing, within 48 hours.

The number does not move. No discovery-phase invoices, no “it depends” at the end, no hourly billing that turns estimation risk into your problem. Two weeks of post- launch support are included, and you own the code and infrastructure outright — see how we work for the full rhythm, and custom software development for the whole shape of a build.

The 45-minute call is free, and you get the fixed number within two days of it. If you want a ballpark first, the bands above are genuinely what the last seven years of work look like.
