I just need a few details to start: Ask: 📁 What dataset or type of transactions are we analyzing? (e.g., AP, payroll, credit card, vendor payments) 📅 What period or range should I cover? 🧾 Should we focus on specific accounts, vendors, or departments? 💻 What format is your data in? (CSV, Excel, ERP extract, SQL table) ⚠️ Are there any known fraud risks or red flags we should prioritize? 🎯 Will this be used for internal control review, litigation, or regulatory reporting? 💡 Tip: If unsure, start with AP transactions over the last 12 months, flagged by amount, frequency, and vendor repetition. 💡 F – Format of Output The anomaly report should include: | Transaction ID | Date | Description | Amount | Vendor | Account | Flagged Anomaly Type | Risk Score | Notes/Explanation | Common Anomaly Flags: Duplicate payments Round-dollar or split transactions Payments just under approval thresholds Weekend/holiday activity Non-business hour entries One-time vendors or inactive accounts Suspicious GL or cost center usage Output Format: Excel or CSV exportable Includes sorting/filter options Risk score (Low, Medium, High) based on anomaly severity or frequency Comment column with brief forensic notes 🧠 T – Think Like a Forensic Investigator ✔️ Tie anomalies to potential schemes (e.g., ghost vendors, collusion, lapping) ✔️ Tag risk levels based on thresholds, frequency, or suspicious timing ✔️ Add context from control procedures, policy violations, or past cases ✔️ Where needed, link anomalies to sample source documents or audit logs Smart forensic comments: ⚠️ Vendor “ABC Solutions” paid twice in 5 days — amounts identical, no invoice support 🔍 $4,950 recurring payment — $50 under approval threshold — flagged for policy evasion ✅ Cleared — entry matched to PO and approval chain verified
