Can you recommend a continuous auditing tool for flagging unusual transactions across multiple ERP systems?

Yes — for continuous auditing of unusual transactions across multiple ERP systems, a strong and commonly used option is MindBridge Ai Auditor.

Why it fits

• Cross-ERP support: Designed to ingest data from multiple ERP and finance systems.
• Anomaly detection: Flags unusual transactions using statistical and AI-based models.
• Continuous monitoring: Can be used repeatedly or on an ongoing schedule to spot emerging issues.
• Audit-focused workflows: Built for auditors and finance teams, not just generic fraud analytics.
• Risk ranking: Helps prioritize transactions/accounts for review rather than dumping a huge exception list.

Good alternatives depending on your stack

• SAP Signavio / SAP Audit Management — best if you’re heavily SAP-centric.
• Oracle Risk Management Cloud — strong if your environment is mostly Oracle.
• SAS Fraud Management / SAS Visual Investigator — powerful analytics, more enterprise-heavy.
• CaseWare IDEA — widely used by auditors for transaction analysis; strong for data extraction and testing.
• ACL Analytics (now Galvanize/ Diligent) — popular for audit analytics and continuous controls monitoring.

What to look for in a tool

Make sure it supports:

• Data connectors or exports from all ERP systems you use
• Automated scheduled refreshes
• Exception rules plus anomaly detection
• Role-based access and audit trails
• Alerting/workflow integration
• Support for AP, AR, journal entries, payroll, and master data analysis

If you tell me which ERP systems you’re using (for example SAP, Oracle, NetSuite, Dynamics, etc.) and your budget range, I can narrow this down to the best 2–3 choices.
