The e-invoicing reform is one of the most significant changes for French businesses since the widespread adoption of VAT. Starting in 2026, all VAT-registered businesses must be able to receive structured electronic invoices. This complete guide explains the timeline, obligations, technical formats, and how to prepare.
What is e-invoicing?
E-invoicing does not simply mean sending a PDF by email. It refers to invoices containing structured, machine-readable data, transmitted via secure and certified channels. An electronic invoice under the reform includes a structured XML file (UBL 2.1 or CII) containing all invoicing data, transmitted via a certified Partner Dematerialization Platform (PDP) or the Public Invoicing Portal (PPF). Simply sending a PDF by email will no longer be considered compliant for B2B exchanges between VAT-registered businesses in France.
2026 reform timeline
The reform is being rolled out progressively based on company size. Here is the official timeline:
- September 1, 2026: reception obligation for all businesses
- September 1, 2026: emission obligation for large enterprises and mid-tier companies
- September 1, 2027: emission obligation for SMEs and micro-enterprises
What does the reception obligation mean?
From September 2026, all businesses, regardless of size, must be able to receive electronic invoices via a certified platform. This means you need to equip yourself with compatible software before that date.
What does the emission obligation mean?
The emission obligation means you will have to send your invoices in structured electronic format (no longer as simple PDFs) via a certified platform. Large businesses will be subject to this from 2026, smaller ones from 2027.
Who is affected?
All VAT-registered businesses established in France are affected by the reform, regardless of their tax regime or size.
- Large enterprises (revenue > 1.5 billion euros)
- Mid-tier companies (ETI)
- Small and medium enterprises (SMEs)
- Micro-enterprises and auto-entrepreneurs subject to VAT
- Associations subject to VAT
E-invoice formats
The reform requires the use of structured formats. Three main formats are accepted by the French tax administration:
- Factur-X: hybrid PDF/A-3 format with embedded CII XML. This is the most widely used format in France as it combines human readability (PDF) with structured data (XML).
- UBL (Universal Business Language) 2.1: pure XML format, international standard widely used on the Peppol network.
- CII (Cross Industry Invoice): XML format from the UN/CEFACT standard, used in European B2B exchanges.
Factur-X, Peppol, ZUGFeRD: understanding the standards
These terms come up frequently in the context of e-invoicing. Here is what they mean in practice.
Factur-X
Factur-X is a Franco-German hybrid e-invoice standard. It is a PDF/A-3 document containing an embedded CII XML file. The PDF is readable by humans while the XML is readable by computer systems. Finovia natively generates Factur-X invoices.
Peppol
Peppol (Pan-European Public Procurement OnLine) is an electronic document exchange network used in over 40 countries. It enables the sending and receiving of electronic invoices in UBL format via certified access points. Finovia is connected to the Peppol network.
ZUGFeRD
ZUGFeRD is the German equivalent of Factur-X. Both standards are technically compatible (same CII base). If you work with German clients, Finovia generates compliant ZUGFeRD invoices.
E-reporting: what is it?
Alongside B2B e-invoicing, the reform introduces e-reporting. This involves transmitting transaction data to the tax administration for operations not covered by mandatory e-invoicing.
- B2C sales (business-to-consumer)
- Sales to businesses not established in France
- International operations
- Cash receipts
How to prepare for the reform
Preparing for the 2026 e-invoicing reform requires a methodical approach. Here are the key steps:
- Audit your current invoicing processes
- Choose a compatible invoicing software (such as Finovia)
- Train your teams on the new processes
- Test electronic invoice generation and reception
- Update your legal notices and invoice templates
- Inform your clients and suppliers about the transition
- Verify your client records are compliant (SIRET, intra-community VAT number)
Choosing your dematerialization platform
To send and receive electronic invoices, you must use a registered Partner Dematerialization Platform (PDP) or the Public Invoicing Portal (PPF). Finovia simplifies this step by natively integrating compliant invoice generation (Factur-X, UBL, CII) and Peppol network connectivity. You have no technical setup to do: Finovia handles compliance for you.
