Why have custom software?

Software developers can take your problem, opportunity, or challenge and turn it into software that does exactly what you need.
When you are facing a challenge that an off the shelf system doesn’t quite fit, custom software developers can create software specifically around your requirements.

To make you more efficient and operate your business your way, custom business software is the key!


Increasing Efficiency

By automating steps you currently do manually, custom software developers can dramatically reduce wasted effort.


Eliminating Mistakes

Mistakes are a common problem that software developers can fix. By automating steps, the mistakes no longer happen.

By developing something specifically for you, our software developers can also guide your team to make things easier for them, reducing or eliminating mistakes.


Giving Visibility

Custom software developers can pull out information from multiple different places and bring it together into a single place so you can easily see critical information.


Standarising Process

One of the keys to growth is standardisation.  While documented processes and procedures are key, staff forget, they make mistakes, or procedures change and they need to be retrained.

Software that works to your process is like a set of guardrails, ensuring everyone does the right thing at the right time.

Imagine in only 7 days...

going from your idea to seeing and reviewing an interactive blueprint that was a clickable preview of how the software could work and function.

    … More No follow up, no response to email, no receipt, nothing since the 29th September.

  • Avatar Adam Hasanovic ☆☆☆☆ 4 years ago
    Initial contact was great while I showed David my software he was very confident. I Paid my $5000+ Scoping fee (I already have and use software I developed on a different platform which I wanted copied to an open source) then it all went … More down hill from there.
    Long story short don’t hand over any money upfront until you are 100% satisfied they can deliver what they promised.

    In 2004, as office manager for Limestone Building Block Co Pty Ltd, I commissioned 1IT to write software to manage inventory and sales for the Company. The system went live on 1 July 2005.
