Methodology and Frameworks
Methodology Agnostic
Fieldguide is methodology agnostic by design. Every methodology has access to the full capabilities of the platform including AI agents, workflows, trial balance, financial statements, document management, analytics, and future innovations, without compromise. As your methodology evolves over time, your content can be updated quickly and deployed across the firm, ensuring a consistent, modern audit experience while preserving your firm’s proprietary approach.
Audit
Fieldguide gives firms the flexibility to use a licensed methodology through our partnerships with Thomson Reuters PPC, Mercia, or CPA Canada, or deploy their own proprietary methodology. As your methodology evolves or your firm adopts a new methodology, Fieldguide evolves with you, never locking you into a single approach.
View Audit MethodologyAdvisory
Advisory firms operate across a broad and shifting set of frameworks, from SOC and HITRUST to ISO 27001, HIPAA, NIST, CMMC, and beyond. Fieldguide supports the full range without forcing a single methodology or locking firms into a rigid structure. Every framework gets access to the same platform capabilities: AI agents, workflows, documentation, and analytics. As your practice adds new frameworks or existing standards change, the platform moves with you.
Internal Audit
Internal audit teams often run risk-based audits, ITGC testing, and ICFR programs (SOX/SOX equivalents) side by side. Fieldguide conforms to global IIA standards and frameworks like COSO through a risk-based approach to audit, and aligns to your organization's existing methodology. Your team gets a repeatable, standards-aligned way to plan, test, and document across every kind of audit.
