Invoice Verification — Proof of Concept
Technical prototype portfolio — demonstration environment
Pick one of 10 bundled sample invoices below. Claude extracts the fields; the math is then verified in code — line items against the subtotal, tax against the rate, subtotal plus tax against the total — not trusted from the model. Where a sample defines expected reference values (vendor, PO number, amount), those are cross-checked against the invoice automatically. Do not submit personal, confidential or client-owned information — this public demo only runs the bundled samples. Contact Chrisian to discuss a controlled evaluation.
Each sample is built to exercise one specific check (or none, for the clean baseline).
Expected: No findings — fully clean
