CFDI finance

CFDI is the digital document that replaced paper invoices in Mexico in 2014. It is generated in XML following SAT schemas, sent to a PAC (Authorized Certification Provider) that validates it and assigns a digital tax seal, and only then is it valid. Variants include: CFDI 4.0 income (invoice), expenses (credit note), transfer (goods movement), payroll, payments. For an ERP, integrating CFDI means: generating the XML per the SAT schema, integrating with a PAC via API, handling responses (accepted, rejected, error codes), storing the stamped XML and the PDF representation, and supporting cancellation with recipient authorization. cifraHQ Enterprise treats CFDI plumbing as a first-class citizen, not a bolt-on module.
