Bangalore, May 16, 2006 Infosys Technologies today announced it has successfully completed a multi million dollar project for Acreis, a new generation financial services company, to deliver its flagship ‘Acreis Once’ bill payment product using the Finacle Universal Banking Solution. Scheduled for a major launch mid 2006, ‘Acreis Once’ will provide Australians with a new way of paying their household bills unlike anything else currently on the market.

‘Acreis Once’ was developed to help consumers better manage their household bill payments in line with their cash flow. Under the ‘Acreis Once’ bill payment service, Acreis will pay its customer’s major household bills (telephone, water, electricity etc) on time, every time via a linked credit facility and provide these customers with a single monthly statement to cover all costs.

Acreis is the first non-banking company to adopt Finacle in Australia (Finacle is also being used by the ANZ Group). It reviewed a number of other banking products before selecting Finacle as the engine behind ‘Acreis Once’ and also chose Infosys to undertake all the systems integration (SI) required for the project.

The project, which commenced in April 2005 and was delivered in January 2006, was completed on time and budget using Infosys’ global delivery model, which saw parts of the design and build completed offshore.

Gary Ebeyan, CEO of Infosys Technologies Australia, commented it was a collaborative effort. “Considerable planning was undertaken with Acreis from the outset to ensure all aspects of the roll-out were effectively managed. Our responsiveness combined with Finacle’s flexibility impressed Acreis,” Ebeyan said. “The beauty of the solution is that it has the scalability to support Acreis’ growth objectives far into the future.”

Ebeyan added that providing the Finacle solution as well as the SI services was instrumental to the project’s success. “This project could become the model for future end-to-end Finacle implementations in Australia” he said.

Stella Doumanis, Chief Operating Officer of Acreis, commented: “Our investment in building this business and this technology platform lays the foundation for Acreis to change the way bills are paid in Australia forever once we launch in ,mid 2006, which we see as enabling us to become a leading provider of retail financial services to Australian households.”
