Tech Hub Australia designs and develops modern digital solutions tailored to how your business actually works — from fast, SEO-ready websites to mobile apps and full web applications like portals, booking systems, CRMs and ERPs. Australian-built, secure by design, and hosted on the cloud.
Website and app development in Sydney from Tech Hub Australia covers custom websites, mobile apps, web applications and business software such as portals, booking systems, CRM and ERP. Everything is Australian-built, secure by design and cloud-hosted, and delivered by a managed IT partner that supports it long after launch.
Off-the-shelf tools rarely fit the way a business actually works, so you end up bending your processes to the software instead of the other way around. Tech Hub Australia designs and develops custom software, websites and applications that match how your team operates — removing manual work, connecting your systems and giving customers and staff a genuinely modern experience.
We build across four areas: fast, SEO-ready websites; native and cross-platform mobile apps; interactive web applications like portals and booking systems; and full business software including custom CRM and ERP. Because we are also a Sydney managed service provider, security, hosting and long-term support are built in from day one — you get a partner, not just a vendor who disappears at launch. A great example is RoamHub360, our own desk and workspace booking platform, built and hosted on the same stack we use for client projects.
Fast, responsive, SEO-optimised websites that look the part and turn visitors into enquiries — designed around your brand and your customers.
Your website is often the first impression a customer forms of your business, and a slow or dated site quietly costs you enquiries. We build custom websites in Sydney that load fast, work flawlessly on every device, and are structured for search engines from the ground up — clean markup, structured data and strong Core Web Vitals performance so customers actually find you on Google.
From corporate and business sites to e-commerce stores and high-converting campaign landing pages, every site is designed around your brand and your goals rather than a rigid template. And because they are easy to update and secure by design, they keep working for you long after launch. Well-built websites also support our IT strategy and digital transformation work.
Bespoke, hand-built websites — no rigid templates. Every layout, interaction and page is designed around your goals for a distinctive, high-performing site.
Professional business and corporate sites that establish credibility, communicate your value clearly, and scale as you grow — with clean structure and fast load times.
High-converting landing pages for campaigns and launches — focused messaging, a single clear call to action, and built-in tracking to prove your return on ad spend.
Online stores that are easy to manage and easy to buy from — secure payments, inventory, shipping and a checkout tuned to reduce drop-off and grow revenue.
Built for search from the ground up — clean markup, structured data, Core Web Vitals performance and on-page SEO so customers find you on Google.
Every site is fully responsive — flawless on desktop, laptop, tablet and mobile — with accessible, standards-based code that works across every modern browser.
Native-quality mobile and cross-platform apps that put your service in your customers' pockets and your operations in your team's hands.
A mobile app puts your business one tap away and unlocks capabilities a website cannot — push notifications, offline access, camera and location features, and a smooth, native experience. Our app development in Sydney covers iOS and Android, whether you need a customer-facing app, a field tool for staff, or an internal application that works wherever your people are.
Where it makes sense, we build cross-platform apps from a single codebase using frameworks such as React Native and Flutter, cutting cost and time-to-market while keeping quality high on both platforms. And when an app-like experience is needed without the app stores, a Progressive Web App (PWA) installs straight from the browser, loads instantly and works offline. We help you choose the right approach rather than defaulting to the most expensive one.
iOS and Android apps built for real-world use — fast, reliable and intuitive, with push notifications, offline support and secure data handling.
One codebase, every device. Cross-platform apps reduce cost and time-to-market while delivering a consistent, high-quality experience on iOS and Android alike.
App-like experiences that install straight from the browser — no app store required. PWAs load instantly, work offline and keep your business one tap away.
Custom web applications that automate the manual work, connect your systems, and give your team a single place to get things done — securely, from anywhere.
A web application is interactive software that runs in the browser and does real work — capturing data, automating workflows and connecting the tools you already use. This is where custom development delivers the biggest return: replacing spreadsheets, manual hand-offs and disconnected systems with one purpose-built application that fits your exact process and scales as you grow.
We build customer and staff portals, booking and reservation systems, internal business tools, workflow automation and API integrations that keep your data in sync across accounting, payments, email and Microsoft 365. Our own RoamHub360 workspace booking platform is a working example of the kind of secure, cloud-hosted web application we deliver — and everything we build sits comfortably alongside our cloud services and cyber security.
Replace spreadsheets and disconnected tools with a purpose-built application that matches your exact workflow and grows with your business.
Secure self-service portals for customers and staff — accounts, documents, requests and status tracking that cut admin and improve experience.
Online booking and reservation systems with availability, confirmations, reminders and an admin dashboard — for desks, appointments, resources or events.
Custom CRMs built around how you actually sell and serve — lead capture, pipelines, follow-ups, notes and reporting, without paying per seat forever.
Bring operations, inventory, finance and people into one connected system — tailored ERP that fits your processes instead of forcing you into someone else's.
Automate the repetitive, error-prone steps — approvals, notifications, data entry and hand-offs — so your team spends time on work that matters.
Connect the tools you already use — accounting, payments, email, Microsoft 365 and more — with reliable API integrations that keep your data in sync.
Applications deployed on scalable, secure cloud infrastructure — including Microsoft Azure — with monitoring, backups and room to grow on demand.
We don't disappear at launch. Ongoing support, security updates, monitoring and continuous improvements keep your software fast, safe and evolving.
We choose the right tools for the job — mature, well-supported technologies that keep your solution fast today and maintainable for years.
A clear, proven process that keeps you in the loop and your project on track — from first conversation to long-term partnership.

Clean, secure, well-structured code built in short iterations you can see progress on.
Functional, cross-browser, responsive and security testing so it works everywhere.

Updates, security patches and a real person to call when you need help.
We measure, learn and iterate — evolving your solution as your business grows.
Real, custom solutions delivered for Australian businesses — automating workflows, removing admin and giving teams tools that actually fit.
A purpose-built lead management CRM for a disability services provider, replacing spreadsheets with an automated, auditable workflow that captures every enquiry and moves it to outcome faster.
An interactive desk-booking application for hybrid workplaces — staff reserve a desk from a live office floor plan, check in and out, and admins get full visibility of utilisation.
An enterprise rostering platform for a multi-site care provider — plans shifts, allocates staff to houses, and catches clashes before they become a problem.
Fast, SEO-optimised, fully responsive websites for businesses across industries — designed to build trust, rank on Google and convert visitors into customers.
Tailored ERP platforms that bring an entire operation into one connected system — inventory, finance, HR, assets and customers — with the automation, reporting and dashboards leaders need to run the business with confidence.
Custom CRM, ERP and line-of-business software that fits how you actually work — no forced workflows, no endless per-seat licensing.
Custom software makes sense when off-the-shelf products can't do what you need, or when you're paying rising per-user fees for features you'll never use. A custom CRM is built around how you actually sell and serve — lead capture, pipelines, follow-ups, notes and reporting — so it drives your process instead of fighting it. Our BB Disability Lead CRM, featured above, replaced spreadsheets with an automated, auditable workflow for an NDIS provider.
A custom ERP goes further, bringing operations, inventory, finance, HR, assets and customers into one connected system with the automation, reporting and dashboards leaders need to run the business with confidence. Because it's tailored, an ERP fits your processes rather than forcing you into someone else's. And for teams already invested in Microsoft, we build rapidly on the Power Platform and Dataverse, giving you secure, governed business apps that integrate cleanly with Microsoft 365 and Azure. Whatever the shape of the solution, our IT consulting team can help you decide whether to build, buy or integrate before a line of code is written.
These terms are often used interchangeably, but they solve different problems. Here's how to tell them apart.
| Aspect | Website | Web application | Mobile app |
|---|---|---|---|
| Main purpose | Inform & convert visitors | Do interactive work | On-the-go, device features |
| Runs where | Any browser | Any browser | Installed on phone/tablet |
| Examples | Corporate site, store | Portal, booking, CRM, ERP | Customer app, field tool |
| Offline use | Limited | Limited (PWA possible) | Yes |
| Push notifications | No | Via PWA | Yes |
| Typical investment | Lower | Medium to high | Medium to high |
Many businesses ultimately need a combination — for example, a marketing website, a customer portal (web app) and a companion mobile app. We help you sequence the build so you get value early and spend where it counts.
We've built websites, apps and business software across many industries. Explore the sectors we serve on our industries page.

Booking and reservation platforms — the space our own RoamHub360 product was built for.
A website is primarily informational — it presents your business and content to visitors, like a corporate site or online store. A web application is interactive software that runs in the browser and does work, such as a booking system, portal, CRM or ERP. A mobile app is installed on a phone or tablet and can use device features like the camera, GPS and push notifications, often working offline. Many projects combine them.
Cost depends on scope. A focused business website is a smaller investment than a custom web application or a native mobile app with integrations. Rather than a fixed price list, we scope each project to your requirements and provide a clear, itemised, no-obligation quote before any work starts, so you know exactly what you are paying for.
Yes. We build custom CRMs and ERPs tailored to how your business actually operates, rather than forcing you into someone else's workflow or per-seat licensing. That includes lead and pipeline management, inventory, finance integration, HR, reporting and dashboards, with the automation your team needs.
Yes. We build secure by design and deploy to scalable, secure cloud infrastructure including Microsoft Azure, with monitoring, backups and room to scale. As a managed service provider we can also handle ongoing hosting, security updates and support after launch.
Absolutely. We do not disappear at go-live. Ongoing support and maintenance covers security patches, monitoring, bug fixes and continuous improvements, keeping your software fast, safe and evolving as your business grows. This can be bundled with our managed IT services.
We choose the right tool for the job from a modern, proven stack: HTML, CSS and JavaScript with frameworks like React, Next.js and Vue on the front end; Node.js, .NET and C# on the back end; WordPress, Shopify or WooCommerce where a CMS or store fits; and the Microsoft Power Platform and Dataverse for rapid business apps. We host on Microsoft Azure with SQL Server, PostgreSQL or MySQL databases.
