IBAN SEPA Payment Preflight

About

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.
