Steps
Generate the FatturaPA XML document conforming to the format specification published by the Agenzia delle Entrate (Italian Revenue Agency); the specification defines the XML schema version, mandatory fields (DatiGenerali, CedentePrestatore, CessionarioCommittente, DatiBeniServizi), and the codice destinatario or PEC address of the recipient
Sign the FatturaPA XML with a qualified electronic signature (XAdES or CAdES) using a certificate issued by an EU trust service provider on the Italian qualified trust list (eIDAS TSL); the SdI rejects unsigned documents
Transmit the signed XML to the SdI via your chosen channel: the SdI web service (SOAP), the SdI FTP channel, or via an intermediary (intermediario) authorized to transmit on your behalf; the codice destinatario in the invoice header directs the SdI to the correct recipient channel
After transmission, poll the SdI for the processing notification: the SdI issues a RicevutaConsegna (delivery receipt) or NotificaMancataConsegna (non-delivery) within the timeframes defined in the technical specifications, and ultimately a NotificaEsito from the recipient indicating acceptance or rejection
Retain the SdI notifications alongside the original signed XML; Italian tax law requires retention of e-invoices and their SdI notifications for the legally mandated retention period
For B2C invoices or foreign customers without an Italian codice destinatario, use codice destinatario 0000000 and separately notify the customer with a paper or PDF copy; the invoice is still routed through SdI
Known gotchas
The codice destinatario is a 7-character alphanumeric code assigned by the SdI to intermediaries and companies; using an incorrect or outdated code causes the SdI to deliver the invoice to the wrong party or return a non-delivery notification
FatturaPA XML must use the exact namespace URI and schema version specified by the Agenzia delle Entrate for the current period; the schema has been revised over time and older versions may still be accepted but newer mandated fields may be missing
The qualified electronic signature certificate must be valid at the time of signing; an expired or revoked certificate causes the SdI to reject the document, and the rejection is not always immediately surfaced — it may appear only in the subsequent notification
