At Grant Thornton, we use a single audit methodology across our global network.


Our audit methodology, Horizon, targets our audit efforts on those areas of your financial statements that represent the greatest risk.


Horizon features integrated quality-control processes, including policies and procedures for engagement quality-control.

Our methodology is underpinned by established processes and cutting-edge technology. We don’t concentrate on robotic verification; rather we ensure compliance and help to improve the way you do business – including systems and internal controls, managing risk, and establishing appropriate accounting policies.

A key element in our global audit methodology is the use of cutting-edge technology. In particular, we use an integrated set of software tools known as the Voyager suite.


Voyager is a tool that helps our audit teams identify financial statement risks, and evaluate the effectiveness of existing processes and internal controls in mitigating risk. The tool also helps our teams document, evaluate and test internal controls, and design improvement strategies.
