The recipient may: a) Express acceptance within three working days from receipt of the request. b) No reply (after 3 business days) is considered as a positive ficta and the invoice will be canceled. c) Refuse cancellation:
  • The issuer may re-submit the request for cancellation of the same CFDI (for the second or subsequent occasion), if the receiver does not expressly consent to such request within three business days (from receipt of the request of cancellation). The tax authority shall be regarded as rejected this request and the proof continues with a status effect (term expired).
  • There is no maximum number of cancellation requests.
  • Taxpayers will be able to cancel a CFDI without the acceptance of the recipient being required in the following cases:
  • Those that cover total amounts of up to $1,000.00 (thousand pesos 00/100 M. N.).

Payment method

If the CFDI is issued for the total value of the operation, and it is paid in a single exhibition, that is, when when you know the form of payment and it is effectively paid at the latest of the last day of the calendar month in which the CFDI is issued, the CFDI must be issued with Payment Method: Payment in a single exhibition (PUE) and it is not necessary to issue a CFDI with the payment add-on.

In case you consider that your customers will not pay you within the current month, you have to issue a CFDI with Payment Method: 99 To be defined and Payment Method: Partial or Deferred Payment (PPD). This creates a second obligation, which is to issue a Payment Supplement for each deposit received (if partial) or for the full payment (if deferred).

Bad practices

The tax authority provided a bad practice guide in the emission of CFDI 4.0:

  1. Require additional data to the RFC, name, denomination or business name, tax regime and postal code of the recipient.
  2. Forcing you to provide an email is optional.
  3. Increase the price of the good or service when the invoice is requested.
  4. Force the recipient to generate the invoice in a portal.
  5. Deny the invoice arguing that it was not requested at the time of the transaction. It can be issued later, as long as it is in the same year in which the operation was carried out .
