Supply Chain Payment Fraud
Every supplier, contractor, and vendor in your payment chain is a potential attack surface. Scammers exploit the complexity of multi-party relationships to intercept payments at the weakest link.

What is supply chain payment fraud?
Supply chain payment fraud targets the flow of money between organisations in a supply chain. From raw material suppliers to manufacturers, distributors, contractors, and end buyers, every payment handoff is a potential interception point. Scammers don't need to compromise your business directly. They just need to compromise one link in the chain.
This is a broader threat than a single payment redirection attack or fake invoice scam. Supply chain fraud exploits the fact that modern businesses rely on networks of suppliers, each with their own payment processes, verification standards, and security postures. Your business may have strong controls, but what about your tier-two suppliers? Or their contractors?
Industries with deep supplier networks are most exposed: construction, manufacturing, healthcare, professional services, and government procurement. The more parties involved in a payment chain, the more opportunities for interception, impersonation, or manipulation.
The complexity itself provides cover. When payments flow through multiple entities, reconciliation is slower, discrepancies are harder to trace, and fraud at one end of the chain may not surface for weeks. By then, the money is long gone.
How supply chain fraud happens
Supply chain fraud targets the gaps between organisations. Every relationship is a potential entry point.
Map the supply chain
The scammer identifies the relationships and payment flows in your supply chain. Public procurement records, LinkedIn connections, industry directories, and even your own website reveal who you work with and how money moves between parties.
Compromise a touchpoint
They target the weakest link. This could be a small subcontractor with poor email security, a supplier's accounts receivable team, or even a logistics partner. One compromised email account gives them visibility into invoices, payment schedules, and bank details across the chain.
Redirect or duplicate payments
Using the compromised position, the scammer intercepts invoices in transit and changes bank details, sends duplicate invoices from a real supplier's account, or creates plausible payment requests from elsewhere in the chain. The payment looks routine.
Exploit detection delays
In a multi-party supply chain, reconciliation is slow. Supplier A thinks Supplier B has been paid. Supplier B thinks the payment is delayed. Your AP team thinks the invoice was legitimate. The gap between payment and discovery can stretch to weeks or months.
Warning signs in your supply chain
Supply chain fraud often hides in the noise of normal operations. These signals should trigger closer inspection.
Bank detail changes from established suppliers
A supplier you've worked with for years suddenly provides new bank details. This is the single most common entry point for supply chain fraud.
Changes at unusual times
Bank detail updates arrive just before a large payment run, end of quarter, or during staff leave when fewer people are checking.
Pressure from upstream or downstream partners
"Our supplier needs urgent payment" or "We need to settle this before the next shipment." Urgency that originates from elsewhere in the chain is harder to verify.
Inconsistent invoicing across the chain
Invoice formats, reference numbers, or payment terms that don't match the established pattern for that supplier relationship.
New contacts for existing suppliers
A different person suddenly handles invoicing or payment queries for a supplier you've dealt with through the same contact for years.
Duplicate or near-duplicate invoices
Two invoices for similar amounts from the same supplier, or invoices that closely mirror a legitimate one with slightly different bank details.

Detect changes instantly
Any change to bank details at any point in your supply chain triggers automatic re-verification. Intercepted invoices with altered details are caught before payment.
End-to-end audit trail
Every verification across your supply chain is logged in a tamper-proof audit trail. Full visibility into who was verified, when, and what changed.
