AI Anomaly & Audit Detection

The honest version most category pages won't give you: most small businesses should not buy a standalone anomaly-detection tool. You already get baseline coverage in your accounting software (QuickBooks, Zoho Books) and your spend tools (Ramp and BILL flag duplicate and out-of-policy payments). The audit-grade platforms here, MindBridge, Trullion, and the enterprise ceiling Feedzai, are for accounting firms and internal-audit teams combing the full ledger for the pattern sampling would miss. You graduate to one when you have a finance function, not just a bigger headcount.
