Custom Software Development

GCD has been developing custom software solutions since 1999. We focus on building custom software that resolves complex and unique business needs when off-the-shelf solutions simply can’t.

Let us take your vision and turn it into a custom software solution that helps you gain greater efficiency and competitive advantage.

Custom Software Vs Off the Shelf Software

Not sure if you need custom software or where to begin? It can be difficult to get to the bottom of what it is you actually need and what solutions are available, which is why we created our video series on Build Vs Buy, where we take a closer look and explain the benefits of each.

Our Stack

How we work

Our Product Development Process is agile, its flexible structure focuses on development sprints rather than a rigid structure. We find this is the best way to ensure value is always at the core of what we do.

Foundation Sprint

The first developmental sprint in a project is provides a core development foundation to build upon through a series of tasks.

Agile Development Sprints

With a blueprint for a plan, the development team begin the build, operating in cycles (sprints) of work targeting prioritised features and epic delivery, with a team goal of delivering working functionality regularly and often.


This phase sees a transition period when the product is “cutover” to the client. To get to here, the product should be designed, built and tested and ready to enter the real world, into the hands of users.


Once the product has been built, the process doesn’t end there. The “final” part of the process in building a great digital product, is supporting it as it enters the real world.

De-Risk your idea

Discovery Sprint

Before embarking on a custom software project, rapidly validate your idea or the problem at hand by using a customer-focused design thinking approach. Our Product Design Sprints are a step-by-step process used to define and test a new product, idea or unique challenge over 4 weeks.
