Web Development in Cairns for the Hard Stuff
A brochure website is one job. A custom web app, an internal tool, an AI integration or the software that joins your systems together is another, and that technical end is where we do our best work.
Book a Free Cairns Development ConsultationCustom software development in Cairns. Compound Co is a Cairns-based web development and custom software studio. We build what off-the-shelf software can't: web applications, integrations between existing systems, internal tools, client portals and AI features.
Custom web apps and software
Web applications, internal tools, dashboards, client portals and SaaS platforms, built when off-the-shelf software can't do the job. WKS Isotec now runs 90% of its order processing without anyone touching it, removing about $100,000 a year in operational cost.
WKS Isotec case study →Joining systems that don't talk
The build we're asked for most in Far North Queensland is a bridge: orders to accounts, enquiries to the CRM, jobs to invoicing. Wherever a person is paid to copy data between two screens, there's usually a build that pays for itself.
Our automation work →AI on the steps that need it
Document processing, classification, drafting and workflow automation tied into your existing systems. A model handles the steps that need judgement, and deterministic code runs everything else, because predictable output matters when it goes to a customer.
AI integration →Custom only when it pays
Off-the-shelf software is cheaper and maintained by someone else, and when it fits we'll say so. Custom earns its cost when your core process fits no product, licences outgrow the build, or systems need joining.
Published pricing →You talk to the builder
A written scope and a fixed quote before any code, then working demos every fortnight. You talk directly to the person building it, which removes most of the risk of something getting lost between the business and the specification.
Yours, and handed over
Built on Next.js, React, Python and Node. Source code, documentation and accounts are in your name from day one, written so another developer could take the project over.
How We Build Your Custom Project
Discovery and Scope (Week 1)
We work through the problem, the users and the systems the build has to work with. You get a written scope and a fixed quote before any code is written.
Prototype (Weeks 2-3)
For anything substantial we build an interactive prototype first, so you can test the core flow before full development, while changing direction is still cheap.
Build (Ongoing, with demos)
Development runs in short cycles with a working demo every two weeks, so you see progress throughout instead of only at the end. Security and performance are part of the build from the start.
Test, Launch, Support
We test against real cases, deploy to Australian or global cloud hosting and hand over clean documentation. Ongoing support and maintenance are available as the business grows.
Frequently Asked Questions
Web design is how a site looks and feels. Web development is what makes it work: the code, the functionality, the integrations and any custom logic behind it. We do both, and the development side is where our custom web apps, software, AI integrations and complex builds sit. For a standard website, see web design in Cairns.
Yes, this is our strongest area. We build custom web applications, internal tools, client portals, dashboards and AI features for problems an off-the-shelf product cannot solve. WKS Isotec now runs 90% of its order processing through a custom build, and BrokerFlux and the NART real estate CRM are two more.
Next.js and React for front ends, Python and Node for back ends, and Claude or OpenAI models where AI adds value. When a simpler approach fits, we use WordPress or Webflow instead. The stack follows the job.
Yes. AI integration is a core part of our work: document processing, classifying enquiries, drafting, workflow automation and custom AI tools tied into your existing systems. We use a model on the steps that need judgement and plain code for everything rule-based.
Yes. Compound Co is based in Cairns and the founder works directly on every project. For technical work that matters: you talk to the person building it, so what you describe is what gets built.
It depends on scope. A custom web app or internal tool typically starts from $7,990, and larger software and SaaS builds are scoped individually. You get a fixed quote after a short discovery conversation, not an hourly rate.
Start by assuming off-the-shelf, because it is cheaper, supported by someone else and updated without you. Custom becomes the better answer in three situations: the process that makes you money does not fit any product on the market, the licence cost of seats you barely use has overtaken the cost of building, or the work is spread across systems that do not talk and someone is paid to copy between them. If none of those apply, we will tell you to buy the product.
You keep it and can run it without us. The source code, the documentation and the hosting accounts are in your name from the start, written so another developer can pick the project up. There is no proprietary layer to licence back from us and no platform you cannot leave.
Yes, and often that is the cheaper path. Many projects are an integration rather than a rebuild: connecting your existing site, accounting file or CRM so data moves without a person in the middle. We are happy to work alongside an in-house developer or an existing agency and to hand over documentation they can work from.
Scope that grows without anyone deciding it should, and a gap between what the business meant and what the specification said. We handle the first with a fixed scope and a fixed quote, where anything new becomes an explicit decision. We handle the second by having the person who builds it be the person you talk to, and by showing working software every fortnight.
Custom Builds That Delivered
“We went from processing every order by hand to having 90% of them run completely on autopilot.”
“The software Compound built has completely transformed how I run my business. What used to take me hours of admin work now happens automatically.”
