Custom Software Development in Sydney

You have tried the SaaS tools. You have duct-taped spreadsheets together. And you are still working around limitations that should not exist. Custom software fixes that. We build applications tailored to how your business actually works, not how a software vendor thinks it should work. The difference now is speed. AI-assisted development means we write, test, and ship code significantly faster than traditional development shops. A project that would have taken three months and cost $50,000 two years ago, we deliver in weeks for a fraction of that. You work directly with the founder. No project managers, no account reps, no six-person team billing hours. Just a focused builder who understands your problem and ships the solution.

We work with businesses across Sydney and New South Wales. While we're based in Melbourne, we work with Sydney businesses remotely with the same level of attention and communication.

Frequently Asked Questions

How quickly can you start a Custom Software project in Sydney?

We can usually start within a week of the initial consultation. Since everything is remote, being in Sydney does not add any lead time. For urgent projects, we can sometimes begin within 48 hours.

Do you offer on-site Custom Software setup in Sydney?

Our setup and onboarding is handled remotely, which is faster and more convenient for businesses in Sydney. We guide you through everything via video call and screen sharing. If you are in Melbourne, we can arrange in-person sessions.

Is Custom Software Development available in Sydney?

Yes. While we are based in Melbourne, we work with businesses across New South Wales and beyond. Everything is done remotely, so your location does not limit what we can build for you.

How much does Custom Software Development cost?

Custom Software Development starts from $4,997, with the final price depending on scope. We quote a fixed price before any work begins, so there are no hourly-billing surprises partway through the project.

Do you offer ongoing Custom Software support for Sydney businesses?

Yes. We offer maintenance and support packages for businesses in Sydney and across New South Wales. This covers bug fixes, updates, and technical support via email and video call, with response times typically within one business day.

Do you have an office in Sydney?

We are based in Melbourne and work remotely with clients in Sydney and across New South Wales. Our remote setup means faster communication and lower overheads, which keeps our pricing competitive.

How is this cheaper than a traditional agency?

AI-assisted development. We use tools like GitHub Copilot, Cursor, and Claude to write boilerplate code, generate tests, and accelerate every part of the development process. This means one senior developer (the founder) can do what used to require a team of three or four. Less overhead, lower cost, faster delivery.

Do I own the code?

Yes, 100%. You get full access to the source code repository from day one. It is your software, deployed to your infrastructure. If you ever want to bring development in-house or switch to another developer, you have everything you need.

What tech stack do you use?

We primarily build with Next.js, React, TypeScript, and PostgreSQL (via Supabase). For mobile, we use React Native. This stack is fast, modern, and well-supported. It also means finding another developer to maintain your code in the future is straightforward.
