The Go Beyond Strategy Draws to A Successful Close for Grant Thornton, Thailand
Grant Thornton, Thailand's exceptional growth, strengthens its position as a leading advisory firm as the Grant Thornton global network’s Go Beyond strategy draws to a successful close.
[Bangkok, 12 January 2026] Grant Thornton in Thailand delivered outstanding growth of 12.3% last year, consistent with the Asia Pacific regional growth rate of 11.2%. The achievement positions the firm as one of the leading contributors to the network's success in the region, combining global standards with local expertise to help businesses navigate complexity and seize opportunities.
The milestone reflects the firm's continued focus on strong governance and high-quality, consistent service excellence. The achievement comes as the global Grant Thornton network reached record revenues of USD 8.5 billion, representing 6.1% growth in constant currency terms, with a global workforce of approximately 80,000 professionals, a 5.3% increase from the previous year.
Commitment to Quality Excellence
A major factor behind Thailand's growth is the firm's unwavering focus on audit quality, supported by the network's comprehensive Audit Quality Indicators (AQIs) framework. These indicators enhance transparency and provide actionable insights that drive continuous improvement in audit performance.
Global Network Quality Highlights:
- High Quality Standards: 78.1% of member firms received "Satisfactory" ratings in quality reviews, supported by the successful rollout of Leap, Grant Thornton's proprietary cloud-based audit technology platform with integrated quality monitoring capabilities.
- Service Line Performance: Assurance services led global growth, increasing 7.9%, followed by advisory (up 4.7%) and tax (up 4.5%), reinforcing the value of the network's multidisciplinary model
- Technology Investment: GTIL continues to elevate audit quality and global consistency through sustained investment in its Leap audit platform, enhanced by the Quality Monitoring Tool (QMT), supported by strengthened innovation governance via the TIGC and service-line TICs, and the advancement of automation and AI to modernise and streamline audit delivery across the network.
- Risk Management: GTIL strengthens its global resilience by managing key risks, spanning private equity ownership shifts, AI driven disruption, geopolitical volatility, regulatory pressures, and rising cyber threats through mandatory security standards, centralised independence controls, and a multilayered governance structure that ensures consistent quality and network wide compliance.
- Thailand Community Engagement: Grant Thornton Thailand leaders have been nominated and appointed as co-chairs across three American Chamber of Commerce in Thailand (AMCHAM Thailand) councils and committees: the Government Affairs Council, the Tax Council, and the Inclusion Committee.
