European invoice verification and supplier verification for e-invoicing compliance in Belgium (mandate live since 1 Jan 2026) and Poland (KSeF): official registry identity, VAT check against VIES, Peppol reachability (BE), IBAN form + key check, bank identified and, in Poland, the official White List: is the IBAN DECLARED by the taxpayer? Paying an undeclared account over 15,000 PLN costs the buyer the VAT deduction and joint liability. Deterministic pret_a_facturer verdict, closed-list reasons.
