Intelligent E-Invoicing Solution for Italy's SDI Platform
Italy pioneered universal e-invoicing in the EU — mandatory for all B2B and B2C transactions since January 2019 via the Sistema di Interscambio (SDI). Every invoice must be issued in FatturaPA XML format and cleared through the SDI hub. InvoStaq's AI engine audits every invoice inside your ERP — zero errors, zero rejections.
Your AI Shield for Italian SDI Compliance
Italy operates the most mature mandatory e-invoicing system in the European Union. The Sistema di Interscambio (SDI), managed by the Agenzia delle Entrate (Revenue Agency), acts as a central clearance hub: every invoice must be submitted in FatturaPA XML format, validated by the SDI, and delivered to the recipient. This applies to all domestic B2B, B2C, and B2G transactions. B2G e-invoicing was mandatory from 2014, B2B for large companies from 2017, and universal coverage (including flat-rate taxpayers) was achieved by 2022. Italy's model has become the reference architecture for CTC (Continuous Transaction Controls) across Europe.

Native ERP Integration
Headless plugins for Microsoft Dynamics 365 and Odoo install natively without middleware or re-platforming. Your teams keep working in the ERP they know.

Mandate Status by Business Sector
Current compliance requirements across B2B, B2G, and B2C transactions.
B2B (Business-to-Business)
Mandatory for all B2B transactions since January 1, 2019. Every invoice between VAT-registered businesses must be issued in FatturaPA XML format and cleared through the SDI. Extended to flat-rate (forfettario) taxpayers from July 1, 2022. Non-compliant invoices are considered not issued for tax purposes.
B2G (Business-to-Government)
B2G e-invoicing was the first mandate in Italy, effective June 6, 2014 for central government and March 31, 2015 for all public administrations. All invoices to public entities must be in FatturaPA format via the SDI. Invoices not submitted electronically cannot be paid.
B2C (Business-to-Consumer)
Italy uniquely mandates e-invoicing for B2C transactions as well. Since January 1, 2019, businesses must issue FatturaPA e-invoices through the SDI even for consumer sales. Consumers can access their invoices via the Agenzia delle Entrate portal or the Fatture e Corrispettivi service.
Key Dates & Milestones
Stay ahead of every deadline — InvoStaq ensures you're compliant before each milestone.
B2G Mandate — Central Government
E-invoicing becomes mandatory for all suppliers to Italian central government ministries and agencies via the SDI in FatturaPA format.
B2B Large Enterprises — Fuel & Subcontractors
Mandatory e-invoicing extended to fuel purchases and public works subcontracting as a precursor to universal B2B coverage.
Universal B2B & B2C Mandate
All domestic transactions — B2B and B2C — must be invoiced via the SDI in FatturaPA XML format. Italy becomes the first EU country with universal e-invoicing.
Flat-Rate Taxpayers Included
Extension of the mandate to contribuenti forfettari (flat-rate regime taxpayers), closing the last remaining exemption. All Italian taxpayers now subject to SDI e-invoicing.
Legal Framework & References
Italy's e-invoicing framework is anchored in the Budget Law 2018 (Legge di Bilancio 2018, L. 205/2017) which mandated universal B2B/B2C e-invoicing from 2019. The SDI was established under Legislative Decree 127/2015, and the FatturaPA format is defined by Decree of the Ministry of Economy and Finance. The Agenzia delle Entrate manages the SDI and issues technical specifications. Italy received an EU Council derogation (Decision 2018/593) to mandate B2B e-invoicing before the EU-wide framework was in place.
