SAN FRANCISCO and BIRMINGHAM, United Kingdom, June 04, 2026 (GLOBE NEWSWIRE) -- Fieldguide, the leader in professional-grade agentic AI for audit and advisory, today announced a partnership with Mercia, the UK’s leading audit methodology and compliance provider, to embed Mercia’s audit methodology throughout the Fieldguide platform.

This partnership marks a significant milestone for the UK audit profession, uniting Mercia’s authoritative guidance with Fieldguide’s intelligent execution to help firms deliver higher-quality work at scale, in full alignment with ISA and the UK Ethical Standards.
“Mercia has spent decades refining our market-leading methodology to enable UK audit firms to work with confidence and compliance.

We’re proud to bring this capability to the firms we serve.”
“Firms across the UK are under the same pressure as their peers globally–they need to do more with less, without compromising on quality or compliance,” said Jin Chang, Co-Founder and CEO of Fieldguide. “By embedding Mercia’s leading methodology into our platform, we’re helping UK firms deliver higher-quality work with more consistency and greater efficiency. This partnership reflects a shared commitment to the future of the profession.”
Through this integration, Mercia’s audit methodology is embedded directly within Fieldguide, giving practitioners a seamless workflow powered by agentic AI without context-switching or external applications. Firms can now leverage out-of-the-box:
- Dynamic risk assessments and audit programmes that adapt to engagement context and autonomously complete full workflows. With Mercia’s methodology embedded directly in Fieldguide, AI agents interpret the guidance alongside client evidence for faster, higher-quality execution–fully aligned to ISA and UK Ethical Standards.
- Automated diagnostics and validation checks that proactively identify inconsistencies or missing evidence, strengthening quality control at every stage of the engagement.
- Continuous methodology updates as Mercia publishes new guidance and standards, they are automatically reflected within the platform to keep teams current and compliant.
This unified experience allows UK firms to maintain quality and compliance without additional administrative overhead.

- Strengthen quality and compliance by aligning every engagement with current ISA standards and UK regulatory requirements.
- Increase capacity and efficiency through intelligent automation of repeatable steps across the audit lifecycle.
