CFDI (Comprobante Fiscal Digital por Internet) is Mexico's mandatory electronic invoicing format. Each invoice is a structured XML that must be digitally signed (timbrado) by an authorized PAC before delivery. OMB Cloud handles CFDI 4.0 issuance, cancellation, and credit notes natively for Mexican entities.
