What we build

Custom software development services we build

Seven categories of custom business software, one Perth team building all of them. Each category has been delivered for real Australian SMBs and is available as a fixed-price scope.

Internal business systems and admin tools

Inventory tracking, job scheduling, approval workflows, reporting dashboards, asset registers, compliance trackers. The operational backbone your business needs but cannot buy off the shelf.

Built for the way your team actually works. Not a generic system you have to bend your processes around. Custom fields, custom rules, custom views.

Internal business systems

Customer and staff portals

Self-service portals where customers check progress, submit requests, download documents, and manage their account. Staff portals for timesheets, leave, internal requests and approvals.

Reduces inbound calls and emails because people can find what they need themselves. Reduces admin because submissions flow straight into your backend systems.

Customer portals & self-service

Workflow automation

Automated data flows between your systems. Triggered notifications when something needs attention. Scheduled reports that land in the right inbox. Approval chains that move without email reminders.

We find the repetitive manual work in your operation and replace it with reliable automation. Not RPA bots that break. Proper logic built into your systems.

Workflow automation software

System integration and data sync

Your accounting software, CRM, eCommerce platform, job management tool, POS, payroll, all connected through proper API integrations. Data flows in real time, not through nightly CSV exports.

We work with Xero, MYOB, QuickBooks, Salesforce, HubSpot, Shopify, WooCommerce, Square, Deputy, Employment Hero, simPRO, ServiceM8, and dozens more.

View all integrations

Legacy software modernisation

That Access database running half your business. The VB6 application nobody can maintain. The PHP 5 system that still works but cannot be extended. We modernise them without losing your data or your workflows.

Sometimes that means wrapping the old system in a modern API so other tools can connect to it. Sometimes it means a full rebuild on modern technology. We will tell you which approach makes sense.

Legacy software modernisation

AI-powered capabilities

Document processing that reads invoices, receipts and forms automatically. Intelligent assistants that answer questions from your business data. Automated categorisation that saves hours of manual sorting.

We build AI into your custom software where it genuinely saves time or money. Not because it is trendy. If a simple rule-based approach works better, we will tell you.

AI solutions for business

Reporting dashboards and business intelligence

Pull data from across your business, accounting, CRM, operations, inventory, HR, into one dashboard. Revenue by customer, profit by project, pipeline by stage, cash flow forecast.

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

Pricing

How we price custom software development services

No hourly billing that spirals, no vague estimates. Here's how fixed-price custom software development actually works, from first call to signed scope.

Free 15-minute call

Tell us what problem you are trying to solve. We will give you an honest answer on whether custom software is the right approach, what it would roughly involve, and what alternatives exist.

Fixed-price quote

After an initial free consultation and a proper discovery phase, you get a fixed price for the entire project. No hourly billing that spirals. You know exactly what it costs before we write a line of code.

Staged delivery

We do not ask for a large sum upfront and disappear for six months. Projects are phased into working releases every few weeks. You see real features early, give feedback, and pay in milestones.

Case Study

Job management system that boosted quoting speed by 50%

We built an end-to-end job management system for an electrical contractor. Quoting, scheduling, field capture and Xero invoicing, all in one platform.

50% Faster quoting
30% More jobs per week
100% Auto-invoiced via Xero

We had three spreadsheets, two databases and an Access system running the whole operation. HELLO PEOPLE replaced it all with one platform that actually talks to Xero. The team stopped fighting the tools and started using them.

Why custom software

What custom software development services actually change

Less admin, better visibility, connected systems, real code ownership. Here's what custom business software development delivers for an Australian SMB, once it's built and running.

Team collaborating around a business workflow on a shared screen

Software that matches how your business actually runs

Off-the-shelf tools force you into their way of working. Custom software does the opposite. It is built around your processes, your terminology, your edge cases.

That means your team uses it from day one without fighting a system that was designed for a different business.

Stop paying people to move data between screens

Most internal admin work is just moving information from one system to another. Copying orders into accounting. Re-entering customer details. Chasing approvals by email.

Custom software removes the human data-bridge. Information enters once and flows where it needs to go.

Connected systems flowing data between business platforms

Your tools talk to each other properly

Xero, MYOB, Salesforce, HubSpot, ServiceM8, Shopify, Square, whatever your business already uses. Custom software connects to all of them through proper API integrations.

No more exporting CSVs and importing them somewhere else. No more two versions of the same data.

Growing business team using scalable internal software

Grows with your business instead of holding it back

Start with the features you need right now. As the business grows, more users, more locations, more complexity, the software grows with you. No rip-and-replace later.

Built on modern cloud infrastructure that handles ten users or ten thousand without re-architecture.

Full ownership of code, data, and IP

You own everything we build. The source code. The designs. The database. The infrastructure configuration. No lock-in, no licensing fees, no dependency on us to keep things running.

If you ever want to take it to another developer, you can. But most clients stick around because we already know the system.

How it works

How a custom software development project runs, step by step

Every custom business software project is different, but the delivery structure stays the same. You always know what week you're in, what's being demoed next, and what still has to happen before go-live.

Discovery & Requirements

We start with a proper chat about what you need. You get a requirements doc, user stories, and a clear project plan.

Architecture & Design

We design the system and sketch out wireframes so you can see how everything fits together before we write any code.

Agile Development

We build in weekly chunks, showing you working features as we go. Real features every week, not a big reveal at the end.

Quality Assurance

We test thoroughly. Performance, security, usability, integrations. All of it before launch.

Deployment & Launch

Cloud deployment on AWS or Azure. Data migration, team training, monitoring from day one. Rollback plan in place.

Ongoing Support

Bug fixes, security updates, new features. Most clients keep us on a monthly plan because we already know the system.

FAQs

Common questions about custom software development

How much do custom software development services cost in Australia?

It depends on scope. A small internal tool starts around 6 to 8 weeks of work; a full custom CRM or operations platform can run 20 to 30 weeks. Every custom software development project is fixed-price scoped after a free 15-minute call, so you know the number before you sign. No hourly billing.

How long does custom software development take from kickoff to launch?

A typical MVP built with our custom software development services runs 10 to 20 weeks from kickoff to production. Bigger platforms with multiple integrations and AI features take 16 to 30 weeks and are delivered in phases so you see working software early.

Can you integrate custom business software with Xero, MYOB or our existing stack?

Yes. Integrations are part of every custom business software development project we run. We connect to Xero, MYOB, QuickBooks, Salesforce, HubSpot, Shopify, WooCommerce, Square, Deputy, Employment Hero, simPRO and ServiceM8 via their APIs.

Do we own the code from a bespoke software development project?

Yes, 100 percent. When the project is paid for, you own source code, designs, documentation and data. No licensing fees, no vendor lock-in, no monthly per-user charges. If you ever want to take it to another developer, you can.

Do you host the custom software you build?

Yes. We deploy to AWS or Azure and can manage infrastructure as part of an optional support plan. You own the cloud accounts and resources outright. If you already have a cloud setup, we deploy inside it.

What happens after the custom software launches?

Thirty days of post-launch support is included with every custom software development project. After that, most clients pick a monthly support plan covering bug fixes, security patches, new features and monitoring. Optional, not mandatory.

Can you modernise our existing legacy system instead of rebuilding from scratch?

Often, yes. We assess whether the existing system can be wrapped, extended or upgraded before recommending a full rebuild. When the business logic still works but the tech is outdated, we modernise incrementally with API layers, new front-ends and database migrations.

Who is HELLO PEOPLE and where are you based?

HELLO PEOPLE is a Perth-based custom software development company. We deliver custom software development services for Australian SMBs across Perth, Melbourne, Sydney, Brisbane and Adelaide. Every project runs through the founder, Kasun, from the scoping call to go-live.
