Intersoft Systems Limited was formed and development of the first systems commenced in late 1981.

In early 1983, Intersoft Systems transferred its business applications to IBM computers.

Code-named "Version 7.0", the resultant suite of systems was released in July 1990 as the Legacy Series.

Since 1990, Intersoft Systems has invested in the development and education of a professional Dealer Network which can provide clients with the professionalism, skill and expertise required by today's progressive business.

This level of service capability heralds a new era in Computer Solutions Dealerships throughout Australasia. Intersoft's "whole product" philosophy implies that dealers offer advisory, training, implementation and ongoing support facilities to clients in addition to the supply of relevant software applications.

In 1991, Intersoft reached agreement with IBM NZ Ltd to market Intersoft products under the IBM Ready /2 Prosper brand name, a unique opportunity. Intersoft worked closely in New Zealand with IBM to ensure that dealers provided quality products with complete hardware/ software solutions to the marketplace.

1995 heralded the release of the first modules of the Performer Series, of which a full range of software products were released during 1996 and 1997. The Performer Series took advantage of new technology to provide improved performance, network capabilities and increased features and facilities.

1998 saw the release of the first of the Intersoft Windows products, the POWER Series. These products paved the way for the new millennium, and ensured clients were kept at the fore of technology and functionality.

1999 and 2000 saw the release of the three key components of the POWER Series: finPOWER, fdPOWER and emPOWER.

2003 saw the release of fdPOWER^SE for the Australian market which allows Users to interface with the NSW and VIC BDM Offices electronically for the registration of Deaths.

2010 saw the release of finPOWER Connect. Developed using the Microsoft .NET framework, finPOWER Connect incorporates the best of the finPOWER system, feedback and enhancements requested by the large User base and the latest development technologies.

September 2013 saw the opening of the finPOWER Australia office in Brisbane.

finPOWER Connect Cloud was released, bringing a mobile-optimised Web-based user-interface to finPOWER Connect.

In 2022 Intersoft purchased our long-time reseller Full Circle Business Solutions Ltd and their NZ and Pacific Island business. Full Circle staff joined our business and Mike Johnson continues to head up the Full Circle Division.

On 1^st May 2024, emPOWER was acquired by Exodesk, New Zealand.

In October 2024, Intersoft proudly announced its acquisition by Jonas Software, a subsidiary of Constellation Software Inc. The strategic transition secured the long-term future of Intersoft and aligned it with one of the world’s most successful software conglomerates.

As part of the Jonas Software family, Intersoft gained access to an unparalleled network of nearly 1,400 software companies worldwide. This wealth of expertise and resources positions Intersoft to drive the ongoing evolution of finPOWER Connect, ensuring it remains at the forefront of financial technology innovation.

The partnership underscores a shared commitment to delivering exceptional value to customers and fostering sustainable growth, further solidifying Intersoft's reputation as a trusted name as a finTech.
