Beginning in January, paper invoices will start to be phased out with transactions transmitted in real time directly to the “AT” (Tax Authority). Consumers will only receive a hard copy if requested. It is another step towards the dematerialisation of invoices as part of the Simplex + initiative. In the initial phase, merchants must install the applications to establish a direct link to the Finanças’ e-fatura system via a “QR” (quick response) code. Consumers will no longer need to give out their taxpayer number.
