Frequently asked questions
Does IBAN & SWIFT/BIC Checksum Validator send my invoice to a server?
The available MVP interaction runs in your browser. Your selected file is not uploaded by this page.
Does this page certify an invoice as compliant?
No. The MVP can show basic fields and local checks, but it does not replace official XSD, Schematron, KoSIT, Peppol, or tax-authority validation.
