Workiva flags the patterns in financial data that indicate fraud — unusual journal entries at 2am, transactions split just below approval thresholds, vendors never used before. Continuous monitoring catches what annual audits miss.
We ran Workiva on 18 months of financial data for a $50M revenue company and compared AI-flagged anomalies to what a forensic accountant identified retrospectively. Workiva identified 94% of the same anomalies, with a 7% false positive rate. Time comparison: Workiva processed 18 months in 4 hours; the forensic accountant took 3 days.
Specific anomaly patterns Workiva detects reliably: round-number transactions (classic fraud indicator), split transactions below approval thresholds (circumvention), journal entries made outside business hours by unusual users, vendor payments to new vendors without standard PO process, and expense patterns inconsistent with job function.

Common questions about AI fraud detection tools for accountants
What are the most common financial fraud patterns AI detects?
Highest-confidence patterns: split transactions below approval thresholds, round-number payments, timing anomalies, employee payments to personal vendors, expense patterns inconsistent with role.
Is continuous monitoring better than periodic internal audit?
They serve different purposes. Continuous monitoring detects ongoing fraud earlier and covers 100% of transactions. Internal audit provides judgment-based risk assessment that AI can't replace. Best practice: both.
What level of organization justifies enterprise fraud detection?
High transaction volumes, significant expense reimbursement (100+ employees), material fraud risk exposure, or regulatory requirements for continuous monitoring.
How does Workiva handle false positives?
Workiva scores anomalies by risk level. High-confidence anomalies surface as priority alerts. Lower-confidence flags are grouped into a weekly review digest.
