Let’s make it
clear.
Do I need to buy a cable or replace my payment terminal?
The association described is logical and registered online. It does not itself require a cable between the payment terminal and fiscal register. Any technical needs of your installation should be assessed separately.
I use Documento Commerciale on line: where should I proceed?
The Agency’s calendar specifies the “Documento Commerciale on line” web procedure for users who do not record and transmit receipts through an Italian fiscal register.
I cannot find my payment terminal code.
Contact your payment service provider to identify the correct terminal. Check that the details match the terminal actually used at the premises.
The deadline has passed: what should I do?
Consult your adviser and the Italian Revenue Agency to assess the situation and the necessary steps. Do not use a new activation date to replace the actual date.
