THE CLIENT'S MANUAL PROCESS:
Invoices arriving daily. Finance downloads PDFs. Types invoice number, vendor, date, amount.
Checks vendor approval manually. Opens database. Searches by name. Reviews previous invoices for duplicates.
Validates purchase orders. Cross-references procurement. Flags missing POs when remembered.
Categories line items one by one. Assigns office supplies, software, marketing. Checks budgets. Notes warnings inconsistently.
Inspects for fraud manually. Round numbers, rushed terms, missing info. Detection varies by experience.
Calculates discounts when time permits. ROI estimated informally. Payment timing without analysis.
Routes for approval informally. Manager for unknowns. Director for limits. Auto-approve inconsistent.
45 minutes per invoice. 320 monthly. 240 hours weekly.
Audit problems - 67 duplicates ($47,200). 142 missed discounts ($28,400). 89 budget overruns discovered late. 23 fraud cases missed. 84% accuracy.

EXTRACTION:
Invoice number, vendor details (name, address, tax ID), dates, PO number, line items (description, quantity, price, amount, category), totals, terms
