Why Grant Thornton?

We have the size, scope, breadth, depth and global reach to serve dynamic organisations around the world. Our teams can provide you with assurance services that deliver real value and support investor confidence.

We coordinate, cooperate and communicate based on our shared global strategy, which ultimately leads to greater consistency and better quality. 

A culture of quality

We approach each audit with sharp thought, straight talk and common sense. In addition to verifying that financial results are fairly presented and meet applicable professional standards, we provide observations and insight into the real performance of your business.

We have a dedicated quality monitoring programme that focuses on the six elements of International Standard on Quality Control (ISQC) 1. Under this programme, we review the audit quality of all our member firms and provide feedback on the design, implementation and operation of their assurance practice quality control.

This rigorous approach helps make sure we deliver consistent, quality services for our clients worldwide over the longer term.

A single global audit approach

We use one audit methodology globally, which means we can offer you consistent, high quality services wherever you are in the world. 

Our audit methodology, Horizon, features a partner-led process that focuses our audit efforts on those areas of your financial statements that represent the greatest risk.

Horizon also features integrated quality-control processes, including policies and procedures for engagement quality-control review. The Horizon methodology is supported by the Voyager suite: an integrated set of six proprietary software tools. 

We continuously evaluate our audit methodology and software applications and provide updated versions annually.

International Financial Reporting Standards

Capability in International Financial Reporting Standards (IFRS) is one of our core skills. We have a full-time team responsible for high quality, consistent application of IFRS throughout the global organisation.

The IFRS team promotes consistency by:

  • offering regular training programmes
  • operating an IFRS helpdesk service
  • publishing extensive technical and interpretive guidance, newsletters and other tools and resources.

We also actively contribute to the development of IFRS. This includes the submission of global comment letters on proposals for new and amended standards as well as participation in roundtables and other events. We are also a member of the IFRS Interpretations Committee, the IFRS Advisory Council and the IFRS for SMEs Implementation Group.
