The company is headquartered in Fortitude Valley in Brisbane, Australia, with other offices in United Kingdom, New Zealand, South Pacific and Asia.

TechnologyOne was founded by Adrian Di Marco in 1987, when he saw an opportunity to build a new generation of accounting software for businesses and government departments, using relational database technology.

[4] TechnologyOne set up its first research & development centre in a demountable office in the car park at Mactaggart’s hide processing plant in Hemmant, Brisbane, in 1987.

[5] In the early 1990s, TechnologyOne built the Automated Titling System (ATS) for the Queensland Department of Natural Resource & Mines.

[16] It also released Ci Anywhere,[17] a version of its Connected Intelligence product hosted in the cloud and available from any desktop or mobile device.

[34] In 2010, TechnologyOne moved into its new $12 million headquarters in Brisbane, which included what was at the time the largest Australian-owned research and development facility.

[37] As of 2021, research largely focuses on developing additional functionalities for TechnologyOne's software-as-a-service enterprise resource planning software.
