Customer portals
Secure logins where clients see their jobs, orders, documents or bookings, so your team answers fewer status calls.
Web Design
Web application development for jobs a website can't do
Web application development for Australian businesses that need a portal, booking tool or dashboard, scoped in writing and built in small stages.
Web apps
When your website needs to do something, not just say something
Rock Solid Marketing provides web application development for Australian businesses whose needs have gone past pages of information. A customer portal where clients see their jobs. A quoting tool that works out a price. A booking system with your own rules. A dashboard that pulls numbers from three places into one screen.
Those are web apps: software that runs in a browser, with logins, data and logic behind it. Our developer Saimul Islam works across Next.js and PHP frameworks such as Laravel, CodeIgniter, Symfony and CakePHP. We scope the app in writing, build the smallest useful version first and add to it in stages, so you see working software early and spend only on what earns its place.
Builds start from our Advanced package at $12,000 + GST, with extra development at $175 + GST an hour quoted before work starts. Your first step is a free 30-minute discovery call.

Common problems
What gets in the way, and how we fix it
Staff run part of the business from a spreadsheet that only one person understands.
What we doWe turn the spreadsheet's rules into a simple web app with logins, so the whole team works from the same data.
Customers phone or email to ask where their job is up to.
What we doA customer portal shows each client their jobs, documents and next steps, without a phone call.
You were quoted a huge sum for an app with every feature at once.
What we doWe build the smallest version that does the core job, test it with real users, then decide what to add next.
What we build

Each part is scoped, built and tested with the people who'll use it.
Booking and quoting tools
Tools that follow your rules: availability, pricing, options and approvals, with results sent to your team.
Dashboards and internal tools
One screen that pulls data from your systems, with roles so each person sees what they need.
Connected to your systems

How it starts
How to plan web application development
We start with the job the app must do and the people who'll use it. What do they do today, step by step? Where does the data come from and where must it go? What's the smallest version that would already save time?
That becomes a written scope with screens, data, connections and a price for the first stage. If an existing tool or a standard website would do the job for less, we'll tell you. Only then do we design and build, showing you working screens as we go.
- The job and the users described
- Today's process mapped step by step
- Data sources and connections listed
- First stage scoped and priced
- Off-the-shelf options checked first
Scope the smallest useful version, then build it.

The estate’s first website, built around its heritage
We approached Rock Solid Marketing to build our online store for our retail division and to look after our existing website. The professionalism of Sean and his team from day one was incredible, they took the time to sit down with us to discuss our exact requirements and they offered suggestions for the build which would improve the overall running of the store.
The finished result of our online store is nothing short of fantastic- it integrates with our point of sale software, it is very easy to navigate, and presents and operates as a professionally made web store should. Since completion and hand over, the back up support we receive from Rock Solid Marketing is remarkable- nothing is too much trouble and we can contact the team at any time with any questions we may have. I have absolutely no hesitation in recommending Sean, Janine and the team from Rock Solid Marketing for building or revamping a website, creating an online store to suit your business or with online marketing.

FAQ
Questions about web apps
Can’t find what you’re after? Call us on 1800 842 022 or browse every answer on our FAQ page.
All FAQsOur web app builds start from the Advanced package at $12,000 + GST. Most apps need more development than a website, charged at $175 + GST an hour and quoted in your written scope before work starts. Building the smallest useful version first keeps the first stage affordable and shows you what's worth adding.
It's building software that runs in a web browser, with logins, stored data and logic, rather than pages of information. Customer portals, booking tools, quoting calculators and internal dashboards are common examples. Users don't install anything; they open a link and sign in. Updates reach everyone at once, because there's nothing to reinstall.
A website app, or web app, looks like a website but lets people do things: log in, enter data, book, calculate or manage records. A website mostly shares information. Many businesses need both, such as a marketing website with a client portal behind a login.
Start with the job and the users, not the features. Map the current process, scope the smallest version that helps, design the key screens, then build and test with real users. After launch, add features in stages based on what people actually use. Skipping the scoping step is the most common cause of blown budgets.
It depends on the scope, so we put a timeline in your written scope rather than guess on the first call. A small first stage takes far less time than a full system. The things that slow projects most are unclear requirements, changing scope and slow decisions, so we agree those early.
Use off-the-shelf software when it fits your process well enough; it's usually cheaper. Build when your process is a real advantage, when tools don't talk to each other, or when you're paying for several products to do one job badly. We check existing options before we quote.
We build web apps that work well on phones, not native apps for the Apple or Google app stores. For most business tools, a mobile-friendly web app is cheaper to build and easier to update, because everyone uses the same version through a browser. If you later need a store app, the web app's back end can usually support it.
Look for a team that scopes in writing, shows working software early and explains choices in plain English. That applies to a web application development agency or a freelancer alike. For web application development Australia wide, ask who will build it, how you'll own the code and data, and what support looks like after launch. Be wary of a fixed price given before anyone has mapped the work.
