Custom Application Development Services

What’s your goal? Because we can build anything.

“What’s your goal?”  That’s the first question our custom application development team will ask.

It’s the most important question because the application we build has to deliver the business outcome that you want.

We can create brand new applications.  We can extend the life of legacy systems so you don’t have to upgrade.  Or we can join one system to another to create new workflows and deliver new revenue or savings.

So, what’s your goal?  Because we can build anything.

If you’re looking for Custom Application Development Services, here’s why you should consider Computer One.

Custom Application Development. Computer One can build anything

Key Application Development Features

Australian-based programming

Our team is all located in Australia – that means we can meet you face-to-face, deliver progress updates in-person, sit with your users and observe their interactions and communicate without risk of an error in translation.


We use an agile development method reinforced by a deep-seated commitment to deliver the stages of your project by the agreed deadlines.


We’re mindful of the risks of application development – it’s easy for a project to go over budget as the scope creeps. We keep you up-to-date so you’re always in control.

Backed by Computer One

With multiple revenue streams, Computer One provides solid financial backing and low risk of business failure during development. If you’ve ever been caught out by an application developer folding overnight, you’ll know this is an important consideration in selecting the right partner.
