# Invoice Three-Way Match Audit

> Invoice Three-Way Match Audit is a paid API for AI agents from rooke-token-risk-pilot.rookepoole.workers.dev, paid per call via x402, $5/call, status unknown (last checked 2026-09-15).

Validates an invoice against a purchase order and goods receipts, detecting quantity discrepancies, price mismatches, and arithmetic errors to determine if the invoice is eligible for payment approval.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability invoice-three-way-match-audit-191b567e -d '<json body>'
```

Example prompt: Run a three-way match audit on invoice INV-9001 from vendor V-42 for $1,250.00 USD — it has one line matching PO line PO-L-7 for 10 units at $125.00 each — and check it against goods receipt GR-88 which shows 10 units received and 0 rejected, with no quantity or price tolerance buffers.

## When to prefer this

Choose this endpoint when you need automated, structured validation that an invoice matches both a purchase order and goods receipts before approving payment — especially in autonomous AP workflows where a machine-readable verdict and disposition recommendation are required. It is well-suited for per-invoice spot checks or automated pipeline integration where configurable tolerances (quantity overage, price overage, rounding) need to be applied consistently. Prefer this over manual review or general-purpose LLM analysis when you need a deterministic, auditable report hash and structured exception list for downstream workflow decisions.

## Known failure modes

- Invoice lines referencing PO line IDs not present in receipts — results in evidence gap or exception
- Declared total does not match sum of line amounts plus tax and shipping — triggers arithmetic exception
- invoicedQuantity exceeds receivedQuantity beyond tolerance — blocking exception flagged
- Unit price overage beyond configured basis points — exception raised
- Malformed currency code or missing required fields — validation error returned
- Receipt array empty or missing lines for referenced PO lines — evidence gap flagged

## How this service works

Public static preview plus paid token controls, risk consensus, AI security, webhook reliability, developer security, schedule risk, decision analysis, API release compatibility, accounts-payable reconciliation, e-commerce return eligibility, SaaS subscription-proration, sales-commission reconciliation, parcel-charge reconciliation, SLA service-credit reconciliation, advertising spend-and-fee audit, contract-renewal audit, workforce timecard reconciliation, hotel booking-commission reconciliation, and warehouse cycle-count adjustment reconciliation products for autonomous agents.

## Output

Returns a structured audit report including a top-level verdict (e.g. MATCHED_WITHIN_TOLERANCE or EXCEPTION), a recommended disposition for the approval workflow, a list of blocking and review exceptions with details, per-line comparisons of invoiced vs. received quantities and prices, potential overpayment exposure in minor currency units, applied tolerance settings, a SHA-256 report hash for audit trail, and evidence gap disclosures (e.g. documents not independently authenticated).
