How do data analytics help detect fraud?

Advanced

Answer

Analytics can test entire populations for red flags: duplicate payments, sequential gaps, round-number or just-below-approval-limit transactions, entries posted at unusual times or by unusual users, vendors matching employee bank details, and anomalous journal entries. This targets high-risk items and patterns that sampling might miss, strengthening the response to fraud risk.
Real-world example Analytics flag several manual journals posted after hours near year-end, which the auditor investigates for override.
