Glossary

An audit trail is a complete, timestamped record of every action, modification, and decision that occurs within a financial workflow. In practice, it captures who did what, when, and based on which source of truth. In finance, audit trails are essential for compliance, internal controls, fraud prevention, and transparent collaboration between teams. They ensure that any financial output, a reconciliation, a labeled transaction, a validated invoice, or a contract extraction, can be traced back step-by-step to its origin.

‍

Traditional audit trails often rely on manual logs, scattered spreadsheets, or ERP notes that only provide partial visibility. As workflows become more automated and data flows across multiple systems, maintaining trustworthy, end-to-end traceability becomes significantly harder.

This is where modern AI-driven finance platforms redefine standards. Within Phacet, every agent action is logged: extractions, matches, flags, corrections, and validations. Each data point is connected to its exact source, down to the line of a PDF or the field of a document. Human-in-the-loop decisions are also recorded, ensuring full transparency for auditors and finance leaders. The result is an audit trail that is not only compliant and secure, but also actionable: teams can review decisions, troubleshoot anomalies, and refine rules or agents with confidence.

‍

A robust audit trail is more than a compliance checkbox; it is the backbone of reliable financial automation. It gives CFOs, controllers, and auditors the assurance that automated workflows remain controlled, explainable, and verifiable, even at scale.
