Frequently Asked Questions

Why does CFDI fail with 'invalid CFDI usage'?

CFDI 4.0 validates that the usage is compatible with the recipient's tax regime. Verify the client's regime and select a valid usage.

Why 'RFC not found in SAT'?

Client's RFC isn't registered or has typos. Request their updated fiscal status certificate.

What's the difference between PUE and PPD?

PUE = cash/immediate payment with actual payment method. PPD = deferred/installment with method 99 and requires a payment complement later.

Payment method not applicable?

PUE must use the actual method (cash, transfer, card). PPD must use 99 (to be defined).
