FatturaPA to CII

Learn how to transform your Italian electronic invoices (FatturaPA) into Cross Industry Invoice format for European e-invoicing compliance.

Understanding FatturaPA Format

FatturaPA (Fattura Elettronica) is the official Italian electronic invoice format mandated by the Agenzia delle Entrate. It's a pure XML format that contains all invoice data in a structured, machine-readable format designed for automatic processing by the Italian tax system (SDI).

Key characteristics of FatturaPA:

• Pure XML format with no visual representation
• Specific Italian tax fields and VAT codes
• Mandatory for all B2B and B2G transactions in Italy
• Requires digital signature for transmission
• Processed through the Sistema di Interscambio (SDI)
• Contains specific Italian fiscal requirements

FatturaPA Structure Example

FatturaPA uses a specific XML schema (SdiFatturaPA). Below is an example of how a supplier is defined in FatturaPA:

<CedentePrestatore>
  <DatiAnagrafici>
    <IdFiscaleIVA>
      <IdPaese>IT</IdPaese>
      <IdCodice>12345678901</IdCodice>
    </IdFiscaleIVA>
    <Anagrafica>
      <Denominazione>Italian Company SRL</Denominazione>
    </Anagrafica>
  </DatiAnagrafici>
  <Sede>
    <Indirizzo>Via Roma 123</Indirizzo>
    <CAP>00100</CAP>
    <Comune>Roma</Comune>
    <Nazione>IT</Nazione>
  </Sede>
</CedentePrestatore>

Understanding CII Format

CII (Cross Industry Invoice) is a European standard for electronic invoicing that provides a common syntax for invoice data exchange. It's designed to be interoperable across different countries and systems while maintaining compliance with EN 16931.

Key characteristics of CII:

• European standard EN 16931 compliant
• Pure XML format without visual presentation
• Designed for cross-border European transactions
• Supports complex business rules and validations
• Widely adopted in European e-invoicing
• Compatible with various national extensions

CII Structure Example

CII uses the UN/CEFACT syntax. The same supplier information in CII format:

<ram:SellerTradeParty>
  <ram:Name>Italian Company SRL</ram:Name>
  <ram:SpecifiedLegalOrganization>
    <ram:ID schemeID="0002">12345678901</ram:ID>
  </ram:SpecifiedLegalOrganization>
  <ram:PostalTradeAddress>
    <ram:PostcodeCode>00100</ram:PostcodeCode>
    <ram:LineOne>Via Roma 123</ram:LineOne>
    <ram:CityName>Roma</ram:CityName>
    <ram:CountryID>IT</ram:CountryID>
  </ram:PostalTradeAddress>
  <ram:SpecifiedTaxRegistration>
    <ram:ID schemeID="VA">IT12345678901</ram:ID>
  </ram:SpecifiedTaxRegistration>
</ram:SellerTradeParty>
