Vendor Invoice Reconciliation Lab

 Create a Vendor Invoice Reconciliation Lab that matches vendor invoices against purchase orders, delivery receipts, and payment records. Support PDF, spreadsheet, and CSV imports, with OCR for scanned invoices when available. Detect quantity mismatches, duplicate invoices, unexpected price changes, tax discrepancies, missing deliveries, and payments that cannot be matched confidently. Display a unified transaction timeline and explain why each match was accepted, rejected, or flagged for review. Include configurable tolerance thresholds, an exception-resolution queue, and audit exports. Treat uncertain matches as review candidates, not confirmed fraud, and preserve the original financial records.
