IBAN SEPA Payment Preflight

Check IBANs, BIC/SWIFT codes and SEPA pain.001 XML locally, with no account, server or cloud.

IBAN SEPA Payment Preflight helps accounting, treasury and ERP teams catch formal payment-data errors before uploading payment batches to a bank portal. Paste supplier bank data, read the clipboard, check selected text, scan the visible page, or open a larger workbench. The extension validates IBAN country length and MOD-97 check digits, checks BIC/SWIFT format, reviews BIC/IBAN country mismatches, and inspects SEPA pain.001 XML for common rejection causes. Local SEPA XML checks include: - pain.001 namespace detection - transaction count vs NbOfTxs - instructed amount sum vs CtrlSum - EUR currency enforcement - duplicate EndToEndId values - past requested execution date warnings Everything runs locally in your browser. There is no bank lookup, BIC directory lookup, sanctions screening, account-owner verification, payment initiation, server, login, analytics or remote code. Important: this is a formal local preflight. It does not confirm account existence, account ownership, BIC registration, bank reachability, sanctions status, fraud risk, creditor legitimacy, bank-specific acceptance or legal compliance.
