Software Development for Sydney Businesses That Need Custom Solutions
Sydney is Australia's largest and most competitive market. The businesses that win here are the ones with systems that actually fit — not generic software that forces workarounds on every second process.
We build custom software for Sydney businesses — web applications, mobile apps, SaaS platforms, internal systems, and the backend integrations that connect your existing tools. Fintech, professional services, logistics, healthcare, startups — we have built for all of them.
HELLO PEOPLE is an Australian software development company with 18 years of experience. Perth-based with lower overheads than Sydney agencies, which means you get senior developers at competitive rates.
Problems Sydney businesses bring to us
These conversations happen every week.
Paying for five tools and still using spreadsheets
CRM, project management, accounting, invoicing, job tracking — none of them talk to each other. The gaps get patched with spreadsheets and manual data entry.
Sydney agencies quoting 3x what this should cost
You have spoken to local agencies. The quotes are enormous. The timelines keep stretching. You need a team that gives you a fixed price and ships on time.
SaaS idea that needs a production-grade build
You have validated the concept. Now you need a team that can build the first version properly — multi-tenant, scalable, Stripe billing — not a throwaway prototype.

Software we build for Sydney businesses
Pick a tab to see the types of software we develop and who they suit.
Custom business and operations software
CRM, job management, quoting, scheduling, inventory, compliance, reporting — operational software your Sydney business needs but cannot find off the shelf.
Built around your actual workflow. Custom fields, rules, role-based dashboards.
Popular with Sydney's financial services, professional services, logistics, healthcare and tech sectors.
Multi-tenant SaaS products
Sydney's startup ecosystem generates ambitious SaaS ideas. We turn them into production-grade platforms — multi-tenant architecture, subscription billing, onboarding flows, admin dashboards.
React, Next.js, Node.js, PostgreSQL, Stripe. Built to scale from first customer to thousands.
MVP to production. We help you ship fast without cutting corners on architecture.
Cross-platform mobile applications
iOS and Android from a single codebase using React Native or Flutter. Native performance at 60–70% of the cost of two separate builds.
Push notifications, offline capability, camera, GPS, barcode scanning.
App Store and Google Play submission handled end-to-end.
API integrations and backend systems
Your software needs a solid backend. We build APIs, database architecture and server-side systems.
Xero, MYOB, Salesforce, HubSpot, Stripe, Square, ServiceM8, simPRO and dozens of other platforms.
Secure, scalable, properly documented.
Replace outdated systems without losing data
Still running Access databases, VB6 apps, or Excel-based systems? We migrate your data and rebuild on a modern, supported stack.
Phased migration so your team keeps working while we build the replacement.
Common with Sydney's established financial services, insurance and professional services firms.
Operations platform that replaced five disconnected tools
We built an end-to-end operations system — quoting, scheduling, field capture, invoicing and reporting in one platform connected to Xero.
Read the full case study →We got quotes from three Sydney agencies — all north of $250K. HELLO PEOPLE delivered the same scope for under half that, on time, and the software actually works the way our team expected it to.
What you get from an Australian software development company
Senior developers, proven process, competitive pricing, and software you own.
Perth-based developers with lower overheads than Sydney shops
We are based in Perth — which means competitive rates without the Sydney overhead. Same experience, same tech stack, same timezone overlap during business hours.
For kickoff workshops and key milestones, we fly in. Sydney is a direct flight from Perth.
Software shaped around how your business actually runs
Off-the-shelf tools force you into their workflow. Custom software does the opposite — built around your processes, your terminology, your edge cases.
Your team adopts it immediately because it fits how they already work.
Integrates with Xero, MYOB and your existing tools
Xero, MYOB, Salesforce, HubSpot, Stripe, Square — whatever your Sydney business runs on. Your software connects through proper API integrations.
Data flows automatically. No CSV exports, no copy-paste between systems.
Grows with your business
Start with core features. Add complexity as the business grows — more users, more locations, more integrations. No rip-and-replace.
Cloud infrastructure that handles ten users or ten thousand without rebuilding.
Full ownership of code, data and IP
You own everything we build. Source code, designs, database, infrastructure. No lock-in, no licensing fees.
Want to bring development in-house later? You take everything with you.

Common questions about software development for Sydney businesses
How much does custom software development cost?
Most projects fall between $30,000 and $200,000 depending on complexity, integrations and platforms. Simple internal tools at the lower end. Complex multi-platform applications with third-party integrations sit higher. Fixed-price quote after discovery — no hourly billing.
You are based in Perth — can you work with Sydney businesses?
Yes — and we do regularly. We overlap your business day fully and visit Sydney for kickoff workshops and key milestones. Our Perth base means lower overheads than most Sydney agencies, which gives you competitive pricing without compromising on experience or quality.
How long does a software project take?
Typical timelines: 8–12 weeks for a simple web application or internal tool. 16–24 weeks for larger systems with mobile apps, integrations and complex business logic.
What technologies do you use?
React, Next.js, Node.js, .NET, React Native, Flutter, Python, PostgreSQL, AWS and Azure. We pick the stack that fits the requirements.
Can you build a SaaS MVP?
Yes. We build MVPs that are production-ready from day one — multi-tenant architecture, Stripe billing, proper auth, scalable infrastructure. Not throwaway prototypes that need rebuilding when you get traction.
Can you replace our legacy system?
Yes. We rebuild legacy Access databases, VB6 apps, Excel-based systems and outdated web apps on modern stacks. Data migration handled. Phased rollout so your team keeps working.
Who owns the software?
You do. Source code, designs, database, hosting — everything. No lock-in, no licensing fees.
Do you provide ongoing support?
Yes. Most clients stay on a support arrangement for bug fixes, security updates, feature additions and maintenance.
