How anomaly-detection AI works
Data ingestion: Pulls millions of GL lines or AP invoices.
Feature engineering: Creates thousands of statistical & relational features (e.g., Benford scores, employee-vendor matches).
ML & rules engine: Unsupervised clustering plus business-rule overlays catch both novel and known risks.
Risk scoring & workflow: Items above threshold route to accountants for review.
Implementation tips
Start small by importing the last two to four years of accounts data.
Iterate monthly; models self-learn as new risks emerge.
[Optional] Tune thresholds with historical anomaly or outlier cases.
Value metrics
% high-risk items auto-cleared vs. false positives
Manual testing hours eliminated
Detected dollar value and number of accounts of misstatements
Reduced internal audit costs

How long to deploy?
