Custom Software & Platform Development in Melbourne
Established Agency is a Melbourne custom software development agency. We design and build custom platforms, web apps, client portals, booking systems, marketplaces and internal tools for businesses that have outgrown spreadsheets and off-the-shelf software. You own the code, it integrates with the systems you already run, and every project starts with a fixed quote.
When custom software makes sense
Your team runs the business across spreadsheets and disconnected tools
You pay for several subscriptions that each do part of the job
The process that makes you money doesn't exist in any product
Staff re-enter the same data into two or three systems
Customers are asking for things your current platform can't do
If an off-the-shelf product does 90% of what you need, buy it. We'll tell you straight in the first call, including when custom is the wrong answer.

Frequently asked questions
How much does custom software development cost in Melbourne?
Every platform is scoped and quoted at a fixed price, so there are no hourly surprises. Cost depends on complexity, integrations and scale. Tell us what you're building and you'll have a fixed quote within 48 hours.
How long does a custom platform take to build?
MVPs typically ship in 6–10 weeks. Larger platforms are delivered in stages, so you're live and learning early instead of waiting for one big launch.
Do we own the code?
Yes. Source code, accounts and infrastructure are yours from day one, with no licence fees and no lock-in.
Should we build custom software or use off-the-shelf SaaS?
If a product does 90% of what you need, buy it. If your advantage lives in the part no product covers, build it. We'll give you a straight answer in the first call.
Can you integrate with our existing systems?
Yes. Xero, CRMs, payment gateways, calendars and most tools with an API. Integration is usually the whole point.
Can you take over an existing codebase?
Often, yes. We audit what you have and tell you honestly whether it's worth keeping or cheaper to rebuild.
Do you only work with Melbourne businesses?
We're based in Melbourne and happy to meet in person, and we build for businesses across Australia.
