Frequently Asked Questions
What does CFDI Timbrado mean?
Timbrado is the digital stamp applied by a PAC (authorized certification provider). It adds a SAT-generated UUID and cryptographic signature (selloSAT) to validate the CFDI. InvoSnap extracts timbrado fields after stamping.
Does InvoSnap handle complementos like Pagos and Nomina?
Yes. InvoSnap parses payment complements (CompPago), payroll complements (CompNomina), and foreign trade complements (CompComExt) and extracts relevant fields into structured output.
Can I extract CFDI from a PDF representation?
Currently InvoSnap processes the CFDI XML file directly. PDF representation of a CFDI loses structured data — we recommend uploading the original XML for best results.
