Mexico requires a CFDI 4.0 (Comprobante Fiscal Digital por Internet) for virtually every transaction. The invoice is an XML stamped in real time by an authorised certification provider (PAC) on behalf of the tax authority (SAT); without the SAT timbre and UUID (Folio Fiscal) it is not valid for tax purposes. Issuers need an RFC tax ID and a digital seal certificate (CSD). VAT (IVA) is 16%. Product/service and payment-method values are validated against official SAT catalogues. Retain records for 5 years.
