Software Development for Adelaide Businesses That Have Outgrown Off-the-Shelf
Adelaide's economy is transforming — defence, space, advanced manufacturing, wine tech and professional services are driving demand for software that generic tools simply cannot deliver.
We build custom software for Adelaide businesses — web applications, mobile apps, internal systems, and the backend integrations that connect your existing tools. React, .NET, Node.js, React Native, Flutter — the right tech for the job.
HELLO PEOPLE is an Australian software development company with 18 years of experience. Perth-based — which makes Adelaide our closest east coast neighbour. Same timezone most of the year, easy flights, and competitive pricing.
Problems Adelaide businesses bring to us
These conversations happen every week with business owners across South Australia.
Disconnected tools and spreadsheet chaos
You pay for CRM, job management, accounting and project tracking — but none of them talk to each other. The gaps get filled with spreadsheets.
Legacy system nobody can modify
You are running an Access database, VB6 application or Excel-macro system that barely works. The developer who built it is long gone.
Limited local development options
Adelaide's tech talent pool is growing but still smaller than Sydney or Melbourne. Finding a reliable software development partner can be difficult.

Software we build for Adelaide businesses
Pick a tab to see the types of software we develop and who they suit.
Custom business and operations software
Job management, quoting, scheduling, inventory, compliance, reporting — operational software your Adelaide business needs but cannot find off the shelf.
Built around your actual workflow. Custom fields, rules, role-based dashboards.
Popular with Adelaide's defence, manufacturing, wine, agriculture, trades and professional services sectors.
Web apps, portals and platforms
Staff portals, customer dashboards, booking platforms, reporting tools — web applications that run in the browser on any device.
React, Next.js, Node.js, .NET — the right stack for your requirements.
Lower deployment cost than native apps, zero App Store delays.
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.
Offline capability for field teams working across South Australia's vast regional areas.
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, Tradify 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 Adelaide's established defence contractors, manufacturers 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.

What you get from an Australian software development company
Nearby team, proven process, competitive pricing, and software you own.
Perth-based — your closest capital city
We are based in Perth — same timezone as Adelaide most of the year, and just a short flight across the Nullarbor. Easy collaboration, easy visits.
For kickoff workshops and key milestones, we come to Adelaide. For everything else, video calls and shared project boards keep things tight.
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 uses it from day one because it fits how they already work.
Integrates with Xero, MYOB and your existing tools
Xero, MYOB, Salesforce, ServiceM8, Tradify, Shopify, Square — whatever your Adelaide business runs on. Your software connects through proper API integrations.
Data flows automatically. No CSV exports, no double entry.
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 Adelaide businesses
