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 — whatever your business needs to run better.
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.

Web apps we build
The most common types of web apps we build for Australian businesses. Pick a tab to see how each one works.
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.
Built with your branding, secured with proper authentication, and connected to whatever your team uses behind the scenes.
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.
Works on desktop and mobile browsers. Field teams use it on their phones, office staff use it on their monitors. Same data, same app.
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.
We have built SaaS products for Australian startups and established businesses turning an internal tool into a commercial product.
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.
Interactive charts, filters, drill-downs. Export to PDF or Excel when you need a snapshot for a board meeting.
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.
Suited for healthcare clinics, trades businesses, professional services, gyms, salons, and anyone who takes appointments or manages field workers.
Custom eCommerce and order management
When Shopify or WooCommerce does not cut it. B2B ordering portals with customer-specific pricing, trade accounts and approval workflows. Complex product configurators. Multi-warehouse inventory.
Connected to your accounting (Xero, MYOB), warehouse management, shipping providers and CRM. Orders flow through without manual re-entry.
Built for Australian businesses that have outgrown template-based online stores and need something that fits their actual sales process.
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.
We keep the workflows your team knows while giving you a platform that is maintainable, secure and extensible for the next decade.
Client portal that cut email volume by 70%
We built a secure document exchange and task tracking portal for an accounting firm. Clients upload, review and approve — all in one place instead of email.

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

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

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.
