Connection Loss

If your POS loses its internet connection or the Italian Tax Agency's ‘Fatture e Corrispettivi’ (Invoices and Payments) portal is temporarily unavailable, transactions cannot be transmitted.

In this situation:

• The app cannot send tax data.
• It is not permitted to ‘synchronise the data later’ as if nothing had happened in the first place.
• It is necessary to follow an alternative procedure in accordance with Italian law.

Fundamental principle

In Italy, the transmission of payments is mandatory.

If it is not possible to transmit at the time of sale, you must:

1. Document the transaction manually.
2. Issue an **electronic invoice **within 12 days.

It is not sufficient to reprint the receipt later.

Correct procedure in case of loss of connection - Issue a temporary paper document

Provide the customer with a simple paper document (manual receipt) certifying the transaction. The document must indicate that the portal was not available at the time of the transaction, for example:

‘Tax Portal was unavailable at the time of issue.’

This document serves as a temporary receipt.

Collect the necessary data - In order to regularise the transaction, you must note down:

• Date and time of the transaction
• Sequential number of the document
• Customer's first and last name
• Customer's tax code
• VAT number and legal name of the trader
• Total amount (taxable amount + VAT)

Issue an electronic invoice within 12 days - To ensure compliance:

• You must transmit the data via an electronic invoicing system
• The invoice must be sent within 12 days of the transaction date
• The electronic invoice replaces the failure to transmit the payment and regularises the sale for tax purposes.

Why is it not possible to synchronise later? In the Italian context:

• The transmission of payments must take place in accordance with the technical rules provided.
• If the system is unable to communicate with the Revenue Agency, the transaction is not recorded.
• It is not permitted to retroactively enter the transaction as if it had been transmitted in real time.

Regularisation can only be achieved through electronic invoicing.

Errors to avoid!

• Doing nothing and hoping that the system will synchronise automatically.
• Not collecting any customer data.
• Not issuing the invoice within 12 days.
• Recording the transaction days later without the correct data.

In summary

If there is no connection:

• Issue the customer a temporary paper receipt
• Note “portal unavailable”
• Collect the customer's first name, surname and tax code
• Issue an electronic invoice within 12 days
• Transmit via the e-invoice system

By following this procedure, even in the event of technical problems, you will remain compliant with Italian legislation.
