In the next 3-5 years, we’re going to see big changes to the audit profession. Audit is moving decisively toward an automated, data-driven future. Using the right tools to increase efficiency and quality so teams can focus on higher risk areas and deliver better outcomes for clients is paramount.

In today’s environment, firms are being asked to do more with less, navigating tighter deadlines, increasing complexity, and growing client expectations. At Thomson Reuters, we are bringing auditors advanced audit technologies, with our newest audit solutions increasing efficiency and accuracy.

But simply adding more AI is not enough. To truly transform audit, AI must be grounded in the same trusted methodology that has underpinned quality audits for decades. That means embedding clear, defensible audit steps; linking them to authoritative guidance; and applying them consistently across engagements—while still giving firms the benefits of automation, full-population testing where appropriate, and richer insights from their data.

That’s why Fieldguide and Thomson Reuters are partnering to provide Thomson Reuters PPC audit methodology, delivered through Guided Assurance, within Fieldguide’s agentic AI platform. Together, we’re giving firms a unified system to apply the trusted methodologies they already use within intelligent, automated workflows—improving quality, efficiency, and client value, all without switching systems or re-entering data.

For decades, firms have relied on Thomson Reuters PPC audit methodology to pass peer review with confidence. Delivered through Guided Assurance, PPC provides trusted frameworks that define quality and compliance across the profession. Those frameworks spell out not only what needs to be done, but also how to document and support that work in a way that stands up to inspection, peer review, and litigation.

Fieldguide’s agentic AI platform is purpose-built for audit and advisory. By bringing professional-grade AI agents directly into practitioners’ daily workflows, the platform streamlines execution, enhances quality, and gives firms the capacity to focus on higher-value client work.

This partnership marks an important milestone for the profession—uniting trusted guidance with intelligent execution to help firms deliver higher-quality work at scale. Beyond individual audit procedures, Fieldguide’s agentic AI platform orchestrates end-to-end workflows, connecting evidence, documentation, risk assessment, and reviewer oversight so firms gain both efficiency and stronger governance across engagements.

Thomson Reuters is excited to extend the automation benefits of Fieldguide’s agentic AI platform to firms using Guided Assurance. Through this partnership, auditors can apply cutting-edge automation alongside the PPC methodology they already know and trust, without having to fundamentally change how they work. It reflects Thomson Reuters commitment to delivering a highly automated, AI-driven audit methodology—powered by our own innovations and collaborations with leading technology providers—and to bringing Fieldguide’s capabilities to the many firms that rely on PPC.

Out of the box, firms can leverage:

• Dynamic risk assessments and audit programs that adapt to engagement context and autonomously complete full workflows. With PPC methodology embedded directly in Fieldguide, AI agents interpret the guidance alongside client evidence for faster, higher-quality execution.
• Automated diagnostics and validation checks that proactively identify inconsistencies or missing evidence, strengthening quality control at every stage.

Together, Thomson Reuters and Fieldguide are helping firms navigate the shift to an AI-powered audit with confidence – grounding automation in the proven guidance auditors rely on. By uniting trusted methodology with intelligent execution, we’re giving professionals a clear path to higher-quality work, stronger compliance, and the capacity to serve clients at a new level. This partnership marks an important step toward the future of audit: more rigorous, more efficient, and powered by AI built for the profession.
