doc forgery vs invoice fraud

a disputed PDF arrives — is it a forged contract or a fraudulent invoice with swapped bank details? both touch PDF metadata, but document forgery is authenticity and revision genealogy; invoice fraud is AP payment redirect and vendor approval chain. counsel and AP need different proof frames.

case b

invoice fraud / vendor account change

fraudulent invoice + bank-detail-change request. tightly coupled to BEC but specifically about the paid-invoice artifact and approval chain.

editorial overlap

lean toward…

disambiguation signals derived from case-type descriptions and common practitioner confusion points.

lean toward doc forgery if you see…

  • ghost text layers, incremental update stack, or signature-chain break on disputed contract or deed PDF
  • PDF revision genealogy anomaly without AP vendor bank-change workflow or bill.com audit trail
  • document-version ghost extractor artifacts — authenticity dispute, not payment redirect chain

lean toward invoice fraud if you see…

  • vendor bank-detail change request embedded in invoice PDF with AP approval-chain tamper
  • bill.com or AP audit log vendor bank-change anomaly tied to paid-invoice artifact
  • invoice PDF revision with routing-number edit in ERP/AP export — not standalone contract authenticity dispute
