Thomson Reuters Announces New Partnerships to Bring AI Automation to Audit Workflows

Thomson Reuters has announced a series of strategic partnerships with Trullion, Audit Sight, Crunchafi, Fieldguide, Validis and Valid8 Financial, expanding its AI-powered audit ecosystem and enhancing its Cloud Audit Suite and Audit Intelligence solutions. The collaborations aim to accelerate automated, data-driven audits by integrating best-of-breed technologies directly into Thomson Reuters’ Guided Assurance platform. 

The company is uniting its PPC methodology used by more than 16,000 U.S. accounting firms with its agentic AI CoCounsel platform and audit solutions to create what it calls “the most automated methodology in the profession,” while preserving compliance with accepted standards. 

“For decades, firms have relied on Thomson Reuters PPC methodology as the gold standard for audit quality, and our vision for AI in auditing starts from that foundation,” said Dave Wyle, general manager of audit. “We’re automating key steps of the methodology not changing it so firms can move faster while staying grounded in trusted frameworks.” 

Automation Across Key Audit Procedures

Trullion, Audit Sight and Crunchafi integrate directly into Guided Assurance to automate major audit procedures: 

• Trullion brings AI-native automation to financial statement review and testing, fully aligned with PPC guidance. 
• Audit Sight reduces manual testing more than 50% by verifying full populations and dynamically eliminating unnecessary procedures. 
• Crunchafi automates lease accounting audits end-to-end, streamlining PPC-based workflows and eliminating manual calculations. 

Fieldguide Integration Enhances AI-Driven Engagements

A new partnership with Fieldguide embeds Guided Assurance into its AI platform. With all 27 PPC industry packs available, AI agents interpret methodology and client evidence in real time, enabling risk-adaptive audit programs and dynamic workflows. 

“Firms are under pressure to do more with less,” said Fieldguide CEO Jin Chang. “By embedding PPC into our platform, we’re helping firms produce higher-quality work with more consistency and less effort.” 

Validis and Valid8 Strengthen Audit Intelligence

• Audit Intelligence Analyze, developed with Validis, uses AI and anomaly detection to highlight high-risk items and streamline testing. 
• Audit Intelligence Test, developed with Valid8 Financial, automates evidence matching and traces transactions to banking data, bringing forensic-level capabilities into standard audit workflows.
