Invoice Verification

Catch invoice risk
before you pay

Checks invoices for duplicate submissions, vendor mismatches, PO/line-item issues, and payment-risk signals before money leaves.

What It Catches

Four fraud vectors checked on submission.

Every invoice runs through the full rule set before a payment decision is made.

Duplicate Invoices

Same invoice billed twice, caught.

PO Mismatches

Line items that don't reconcile.

Bank-Change Fraud

Vendor banking details changed mid-stream.

Payment Anomalies

Amounts that break the math.

How It Works

Three steps to a risk verdict.

01

Upload invoice

Submit a PDF, URL, or structured JSON payload via the API or dashboard.

02

Evidence cross-checked

A rule engine checks for duplicates, bank-detail changes, missing POs, and round-number anomalies across the invoices you submit.

03

Risk verdict issued

A backend-generated Proof ID is issued for every verification run you can reference later.

Example output (illustrative)

What a verified invoice looks like.

Every verified invoice produces a structured proof record you can export or share with auditors. The example below shows the structure — backend proof IDs are generated per-run.

Note: Persistent BEC protection (bank-account-change detection across submissions) requires prior vendor banking context or an enterprise data feed integration. It is not available from a context-free self-serve sample alone.
