Custom Web Application Development
Custom web application development for Australian businesses that have outgrown spreadsheets and generic SaaS. We design and build secure customer portals, internal business tools, SaaS platforms and API integrations with React, Next.js and Node.js, quoted at a fixed price against a documented scope, with the code and IP handed over to you.
A custom web application is software your business owns and runs in a browser, built around your specific workflows rather than your team adapting to someone else's product. The right time to commission one is when off-the-shelf SaaS keeps costing you more in workarounds, manual handoffs, or per-seat fees than a one-time build would. The wrong time is when a $50/month SaaS already covers 90% of what you need, and we'll tell you that honestly. We work with Australian businesses whose operations have outgrown spreadsheets, generic CRMs, and patched-together no-code tools, and who need something that scales as they grow without rebuilding from scratch every two years.
What We Deliver
Why Choose Us
Scalability
Architected so adding customers, users and features does not mean starting again from scratch.
Security
Role-based access, encrypted connections and secure coding practices go in from the first sprint, when they are cheapest to add.
Speed
Pages that load fast on a phone over 4G.
The tech we build on, and why
What each part of the stack does for your project.
React
React's component model means every feature we ship reuses what came before. So iteration two is faster than iteration one, with a smaller surface for bugs to hide and a tighter feedback loop when you want to change direction.
Next.js
Server-rendered HTML by default. That means Google can read your pages without running JavaScript, your customers see content quickly, and we don't fight the framework to get good Core Web Vitals scores.
Node.js
Running JavaScript on the server lets one team own both frontend and backend. That keeps the team small, the cost down and the boundary between systems simpler, and the same engineer who built the customer-facing dashboard can wire up the API behind it.
Our Process
Architecture
Data model, hosting and integrations planned before code.
Frontend
Building responsive, accessible interfaces with React.
Backend
Developing secure APIs and database schemas.
QA
Automated tests plus manual testing before each release.
What we typically build
Common projects. Where we've built one, it links to the case study.
SaaS platforms
Multi-tenant applications with billing, role-based access, and customer-facing dashboards, built to scale from your first paying customer to your thousandth.
See Repify case studyCustomer portals
Secure self-service portals where your customers place orders, manage their accounts and download invoices without calling your team.
See TG Linen Portal case studyIndustry-specific business tools
Operational software shaped around how your business runs. It replaces the spreadsheets and patched-together no-code tools your team has been working around.
Financial and property tools
Mortgage, lending, and real estate platforms with the data integrity, audit trails, and access controls the sector demands.
Industries We Serve
Each industry page covers the workflows, integrations and compliance rules we design around.
Healthcare
Clinics and allied health practices run on a practice management system plus a pile of forms, phone calls and spreadsheets around it. We build patient portals, intake forms and integrations that cut that admin, designed around the Australian Privacy Principles from the start.
Professional Services
In a law firm, accounting practice or consultancy, every hour spent chasing documents or rekeying time sheets is an hour nobody bills. We build client portals, workflow automation and integrations with Xero and your practice software to take that admin off your team.
Mining
Mine sites and contractors work hours from the nearest town, often with no reception. We build offline-first field apps, safety and inspection tools and reporting dashboards that sync when a device gets back in range.
Education
Most RTOs and training providers already have an LMS. What hurts is the work around it: enrolments, AVETMISS reporting, and student data copied between systems. We build student portals, reporting automation and integrations to fix that, and full learning platforms when an off-the-shelf LMS doesn't fit.
Tourism
Every booking that comes through an OTA costs a commission. For tour operators, accommodation and venues, we build direct booking flows, guest apps and back-office tools, and connect them to the channel manager and payment provider you already use.
Finance
Brokers, advisers and lenders want clients to log in and see where things stand, but every screen carries ASIC and privacy obligations. We build client portals, document handling and workflow tools with the access controls and audit trails that work needs.
Frequently asked questions
What's the difference between a custom web app and a website?
A website is for people to read; a web app is for people to do something: log in, manage data, run a workflow. If your users will mostly browse, you want a website (see our website development services). If they'll log in and do work, you want a web app.
How much does a custom web app cost in Australia?
Most of our web app builds land between $50,000 and $250,000, depending on scope. The major drivers are the number of user roles, integrations with other systems, and how custom your workflows are. Our full pricing breakdown walks through every range in detail.
Do you build secure customer and web portals?
Yes. Customer portals are one of the most common things we build: secure logins, role-based permissions so each customer only sees their own data, ordering, documents and invoices. The TG Linen Portal is one example. For budgets, see what a customer portal costs in Australia.
Can you integrate with our existing systems and APIs?
Yes. API integration is part of most web apps we build, whether that is pushing invoices to Xero, syncing customers with your CRM or pulling data from a supplier's system. Where a system has no usable API, we will tell you up front what the workaround costs. For integrations without a new app, see business automation.
How long does it take?
Mid-range builds typically take 2-4 months from kickoff to first production release, then iterate from there. For more detail by project size, see our timeline guide.
Do you work with businesses outside Brisbane?
Yes. We are based in Brisbane and work with businesses across Australia. Discovery workshops and weekly demos run well over video, and we meet in person where it makes sense. If you are still weighing up options, our guide to custom software development explains how we work.
Do you build mobile apps too?
Yes. Many of our web apps include a mobile companion; see iOS and Android development. For most business apps, a responsive web app handles mobile fine without a separate native build, and we'll tell you which approach fits your case.
What happens after launch?
Hosting, monitoring, security patches, and feature updates are part of our ongoing support service. Most clients keep us on retainer for 6-12 months post-launch as the app finds its first users and the rough edges surface.
Where We Work
We work with businesses across Australia from our Brisbane base. These cities have their own pages for this service.
