Web Applications That Replace Spreadsheets, Workarounds and Disconnected Tools

A web app is software that runs in a browser. No installs, no app stores, no compatibility headaches. Your team opens a URL and gets a system built around how your business actually operates.

We build custom web applications for Australian businesses that have outgrown off-the-shelf tools. Customer portals, internal operations platforms, reporting dashboards, booking systems, SaaS products. Client-side and server-side — the full stack built around your needs.

HELLO PEOPLE is a Perth-based web application development company. We use modern frameworks like React, Laravel and Node.js to build fast, secure, scalable web apps that integrate with your existing business tools.

When off-the-shelf software falls short

If your business is running on a combination of these, a custom web application is probably overdue.

Spreadsheets doing the heavy lifting

Your critical data lives in Excel or Google Sheets. Multiple people edit the same file. Formulas break. Nobody trusts the numbers without checking them first.

Three SaaS tools that kind of work

You are paying for multiple subscriptions and none of them do everything you need. Your team jumps between tabs all day, manually copying data from one tool to another.

Customers calling for updates they should get online

Your team spends hours answering status enquiries, sending documents by email, and manually processing requests that a self-service portal would handle.

What We Build

Web apps we build

Portals, operations platforms, dashboards, booking systems, SaaS products and more. Each one solves a different business problem.

Customer and staff portals

Self-service portals where your customers log in, check status updates, download documents, submit requests and manage their account. Staff portals for timesheets, leave, internal approvals and knowledge bases.

Reduces the volume of calls and emails your team handles because people find what they need themselves. Forms and submissions flow directly into your backend systems.

Customer portals & self-service

Internal operations and workflow apps

Job tracking, inventory management, scheduling, approvals, compliance checklists, asset registers. The operational tools your business runs on, built as a web app your team accesses from anywhere.

Replaces the patchwork of spreadsheets, shared folders and disconnected tools that most growing businesses end up with. One system, one login, one source of truth.

Internal business systems

SaaS and multi-tenant web applications

If you are building a software product, something your customers pay to use, we build the web application, subscription management, onboarding flows, admin dashboards and API layer.

Multi-tenant architecture so each customer gets their own data space. Role-based access, usage tracking, billing integration with Stripe or similar.

Custom software development

Reporting dashboards and data apps

Pull data from across your business (accounting, CRM, operations, inventory, HR) into one web-based dashboard. Revenue by customer, profit by project, pipeline by stage, real-time KPIs.

Updated automatically. No more waiting for someone to compile the monthly report. Your leadership team sees the numbers as they happen, from any device.

Dashboard & reporting software

Booking, scheduling and appointment apps

Online booking systems where customers select a service, pick a time, and confirm without calling your office. Staff scheduling tools that manage rosters, availability and assignments.

Automated reminders via email or SMS. Calendar sync with Google or Outlook. Payment collection at booking if you need it.

Booking & scheduling software

Legacy system rebuilds as modern web apps

That old desktop application, Access database, or VB6 system your business still depends on, rebuilt as a modern, browser-based web application. Same business logic, better technology.

Your team accesses it from anywhere instead of being locked to one machine. Data migrated across cleanly. New integrations with your current tools become possible.

Why a Custom Web App

What changes when you build the right tool

Less admin, real-time data, connected systems. Here is what a custom web application actually delivers for your business.

Web application running across laptop, tablet and phone screens

Works on any device with a browser

No installs. No app store approvals. No compatibility issues across Windows, Mac, iOS and Android. Your team opens a URL and gets to work.

Web apps update instantly for everyone. Push a change once and every user sees it immediately. No waiting for downloads or version conflicts.

Team viewing real-time dashboard data across multiple screens

Live data across your whole team

Everyone works from the same data. When someone updates an order, submits a form, or changes a status, everyone else sees it straight away.

No more emailing spreadsheets around. No more "which version is the latest?" conversations. The web app is always the single source of truth.

Connected business systems sharing data through a web application

Integrates with your existing business tools

Your web app talks to Xero, MYOB, HubSpot, Salesforce, Shopify, Square, simPRO, ServiceM8 and whatever else your business runs on. Data flows automatically between systems.

No more copying data between screens. The web app becomes the hub that connects your operations, accounting and customer-facing tools.

Scalable cloud infrastructure architecture diagram

Handles growth without re-architecture

Start with ten users, scale to ten thousand. Cloud infrastructure on AWS or Azure means the app grows with your business. More traffic, more data, more complexity, without rebuilding.

We build with modern frameworks (React, Next.js, Laravel, Node.js) designed for performance at scale. Fast load times, responsive interfaces, efficient backends.

Secure login interface with multi-factor authentication

Enterprise-grade security built in

Role-based access control, encrypted data at rest and in transit, multi-factor authentication, session management, audit logging. Security is not an afterthought. It is part of the architecture.

We follow OWASP best practices and Australian data handling requirements. Your data stays in Australian data centres unless you say otherwise.

Pricing

How we price web app development

No hourly billing that spirals. No vague estimates. Here is how we approach pricing.

Free 15-minute call

Tell us what the web app needs to do. We will give you a straight answer on what is involved, whether a web app is the right approach, and what the realistic next steps look like.

Fixed-price quote

After a free consultation and discovery phase, you get a fixed price for the project. No hourly billing that spirals. You know what it costs before we start building.

Staged delivery

We break the project into phases, each delivering working features. You see real progress every few weeks, give feedback as we go, and pay in milestones tied to what has been delivered.

How It Works

How the Project Works

Every web app is different. The process adapts, but the structure stays the same.

Discovery & Scoping

We map your requirements, user types, data flows and integration points. You get a clear scope document and project plan.

UX Design & Prototyping

Wireframes and clickable prototypes so you can see the app before we build it. We test usability early, not after launch.

Frontend & Backend Build

We build in weekly sprints. Working features every week: real screens, real data, real interactions. Not a big reveal at the end.

Integrations & APIs

We connect your web app to Xero, MYOB, HubSpot, Shopify, Stripe, or whatever your business already uses. Proper API work with error handling.

Testing & Launch

Performance, security, cross-browser and mobile testing. Data migration if needed. Team training. Monitoring from day one.

Support & Iteration

Bug fixes, security patches, new features, performance monitoring. Most clients stay with us because we already know the system.

We needed a portal where our clients could log in, see their project status, and download reports. HELLO PEOPLE built it in eight weeks and connected it to our Xero and HubSpot. Our support inbox dropped by half.

FAQs

Common questions about web app development

What is a web app and how is it different from a website?

A website delivers information, pages you read. A web application lets users do things: log in, submit data, manage records, run workflows, view dashboards. It runs in a browser but behaves like software. Think of it as a business tool that happens to live at a URL.

How much does web app development cost?

Every project is different, so we do not publish fixed price ranges. We offer a free initial consultation to understand what you need, followed by a discovery phase. After that, you get a fixed-price quote for the full project. No hourly surprises. Book a free 15-minute call and we will give you an honest steer.

How long does it take to build a web application?

A focused web app (a portal, booking system, or internal tool) typically takes 8 to 16 weeks from kickoff to launch. Larger platforms with multiple user types, integrations and reporting may take 16 to 30 weeks, delivered in phases so you see working features early.

What technologies do you use to build web apps?

We use React and Next.js for front-end interfaces, Laravel and Node.js for backends and APIs, PostgreSQL and MySQL for databases, and AWS or Azure for cloud hosting. We pick the stack that fits your project, not whatever is fashionable this month.

Can you connect the web app to our existing business systems?

Yes. We integrate with Xero, MYOB, QuickBooks, Salesforce, HubSpot, Shopify, WooCommerce, Square, Stripe, Deputy, Employment Hero, simPRO, ServiceM8 and dozens of other platforms via their APIs. Your web app becomes the central hub.

Do I own the code?

Yes, 100 percent. Source code, designs, databases, infrastructure configuration. All yours. No licensing fees, no lock-in. If you want to move to another developer down the track, you can.

Will the web app work on mobile?

Yes. Every web app we build is responsive. It works properly on phones, tablets and desktops. For most business use cases, a well-built responsive web app eliminates the need for separate iOS and Android apps entirely.

Do you provide hosting and ongoing support?

Yes. We deploy to AWS or Azure and offer monthly support plans covering bug fixes, security updates, new features and performance monitoring. You own the hosting accounts and infrastructure. We manage it as part of the support arrangement.
