Visualizador CFDI XML

The Comprobante Fiscal Digital por Internet (CFDI) is the mandatory electronic invoicing mechanism established by Mexico tax authority, the Servicio de Administración Tributaria (SAT). All commercial sales, professional fees, payroll payments, and credit transactions in Mexico must generate a digitally stamped XML invoice.

Understanding the internal structure of a CFDI file is necessary for accountants, business owners, and administrative staff. Raw XML documents contain technical namespace attributes that make reading invoice totals, tax withholdings, and product descriptions difficult without specialized visualization software.

This CFDI 4.0 and 3.3 XML Viewer decodes Mexican tax invoices directly inside your web browser. It extracts seller and buyer tax IDs (RFC), itemizes line items and unit measures, calculates transferred and withheld taxes (IVA, ISR, IEPS), and formats the digital tax stamp (Timbre Fiscal Digital) into a clean, printable document view.
