Revenue Leakage Investigator

 Create a revenue leakage investigator that analyzes imported invoices, contracts, usage records, price lists, credits, refunds, and payment transactions to uncover potential missed revenue or billing inconsistencies. Detect unbilled usage, duplicate credits, incorrect rates, expired discounts, mismatched quantities, missing invoice periods, and unexplained differences between contracted and billed amounts. Show the source records behind each finding, estimate the potential financial impact, and provide a review queue for finance teams. Distinguish confirmed discrepancies from possible issues and never automatically charge customers or modify accounting records.
