The fraud firewall

Catch the fraud before the money moves.

Two sentences we treat as contract terms

Advisory, never blocking — releasing money is always a human act.

Every signal is deterministic and explainable — no ML black box.

Three tiers of deterministic screening stand between an invoice and a payment — each one a set of rules a person can read and an auditor can question. What follows is the shape of the shield, not its blueprints: the full detector matrix is walked through in a demo, not published.

Even a born-clean invoice is corroborated — not trusted.

Pixels, arithmetic and conformance can all pass and the document can still be fabricated — an AI can generate a clean one. So when an invoice checks out on its face, Aurenta doesn't stop at the image: it corroborates the claim against out-of-document truth — public registries, your own buyer feeds, and your payment history. A first-time vendor paid into a first-time bank account raises an advisory REVIEW, fused with the checks below. Advisory, never blocking — releasing money is always a human act. Every signal is deterministic and explainable — no ML black box.

Three-way PO / GRN match

Each invoice is reconciled against your purchase-order and goods-receipt feed. A fabricated PO reference, billing beyond the authorised PO total, or billing before goods are received all surface — deterministic and advisory.

TRN-registry existence check

A seller's tax-registration number can be perfectly well-formed and still not exist. Aurenta checks it against the registry: format-valid is not the same as real.

Cross-tenant mule detection

One payee account quietly collecting for several unrelated sellers — across independent customers — is caught with a privacy-preserving one-way fingerprint. The account number itself is never stored.

First-seen payee prior

A first-time vendor paid into a first-time account is the classic set-up for a redirected payment. It raises an advisory REVIEW so a person looks before the money moves.

Three screens around every payment run Invoices approach from outside through three concentric screening rings toward the sealed payment run at the centre. Most cross all three rings and carry a green check. One invoice is held at the middle ring for human review; one is stopped at the outer ring with its reason recorded. Beneath the figure: advisory, never blocking. TIER 1 · THE DOCUMENT ITSELF TIER 2 · ITS HISTORY TIER 3 · THE WHOLE NETWORK REVIEW · a human decides HELD · reason recorded THE PAYMENT RUN
Three screens between an invoice and the payment run — every hold explained in writing, every release a human act.

Tier 1 Per document

Every invoice is examined on its own before anything else sees it: the figures are recomputed exactly, the identifiers are checked for tampering and disguise, and the document's own story — dates, sequences, structure — has to hold together. An invoice that lies about itself never reaches a payment run.

Tier 2 Behavioural

Each document is then judged against history — what this vendor normally does, how invoices usually arrive, and what changed since the last time money moved. The quiet deviations that precede most payment fraud surface for a person to look at, with the reason written out.

Tier 3 Network & file

The widest lens looks across relationships and at the files themselves: patterns that only appear when your whole trading graph is considered at once, and the evidence a document carries about its own history. What no single invoice reveals, the network does.

The Payment-Run Firewall

Screen the payment proposal CSV thirty minutes before money moves — a per-line pay/hold recommendation, sealed as evidence.

It is the category most competitors don't have: not another approval step, but a deterministic screen at the exact moment the loss becomes irreversible. Advisory, never blocking — releasing money is always a human act.
