Is a KEP address required for e-invoice

By: Ayyıldızsoft

KEP adresi ve e-fatura kutusunu ayıran illüstrasyon

A KEP address is not written on every file as a requirement for sending e-invoices. KEP is registered electronic mail. An e-invoice is a document that goes to the buyer’s e-invoice box. The KEP page describes the address. Ayyıldızsoft does not add an unneeded KEP to a setup at the Konya e-invoice office.

A tender, a formal notice or a contract may ask for KEP. That need is not part of the e-invoice application. The invoice still goes with a seal or a signature: financial seal. Putting an invoice in an email attachment and calling it KEP is also wrong. e-Retention and a KEP archive are not the same thing.

Not the invoice inbox

  1. See if the papers mention KEP
  2. If they do not, do not add it to the e-invoice file
  3. If they do, do not treat the address as the invoice inbox
