GPT iBuy 2.0

PhoenixDX exceeds GPT’s employee expectations in designing a complete new e-procurement platform via OutSystems.

The GPT Group is one of Australia’s largest diversified property groups and a top 50 ASX listed company. They own and manage over $25 billion in retail, office and logistics property assets across Australia.

The Challenge

GPT’s existing procurement application (iBuy) was soon to be unsupported and had numerous usability and performance issues.

The PhoenixDX Solution

Leveraging the power of the OutSystems platform, PhoenixDX built iBuy 2.0 with a focus on improving user experience and productivity. The new application delivered and upgraded the Supplier Management, Purchase Order Management, Service Receipting and Invoice Tracking systems. iBuy 2.0 also offers improved search capability, delivered personalisation through customisable display columns and gave staff a new workspace for quick access to routine tasks.


  • A 60% reduction in the time taken to complete key tasks.
  • Reduced training budget due to superior and more intuitive UI.
  • Extensive user experience analysis and investment in UI paid off. GPT pride themselves on employee satisfaction and providing sophisticated tools that allow staff to do their job more efficiently.
  • This procurement project helped GPT kick off their digital transformation strategy. OutSystems is now the centrepiece of the GPT Digital Business Platform for custom web and mobile applications. Because of the fantastic results with iBuy 2.0, GPT has decided on OutSystems as the default frontend for all apps designed for customers, employees, suppliers and tenants.


What They Say

“The end product speaks for itself. I heard nothing but good things, with our people really itching to get on the platform and use it. Fantastic outcome.”
