Enter your tax details exactly as they appear on your Constancia de Situación Fiscal (the tax status certificate issued by the SAT, Mexico's tax authority): RFC (Mexican tax ID), legal name without «S.A. de C.V.», tax regime and postal code. If a value does not match the SAT records, the CFDI (Mexican electronic invoice) is rejected and we notify you by email so you can correct it; when you save, it is issued again.

Download the XML and the PDF of each CFDI in Invoices. If you do not request a CFDI in your name, your payment is included in the month's global invoice. You can request a reissued invoice within the same month.
