French e-invoicing reform 2026: complete guide for foreign businesses selling to France

If your business is based in Germany, Italy, Spain, the Netherlands, the UK, or anywhere outside France — and you have French B2B clients — France's 2026 e-invoicing mandate affects you directly. Starting September 2026, your French clients will be legally required to receive invoices in structured electronic formats. That means the PDFs and Word documents you're currently sending may no longer be accepted.

This guide explains who is affected, which formats are accepted, what the deadlines are, and how Bonne Facture makes compliance effortless — even if you've never heard of Factur-X before.

Who is affected by the reform?

The short answer: any foreign company that issues B2B invoices to French entities.

France's reform (Ordonnance n° 2021-1190 and its implementing decrees) targets transactions between businesses registered for VAT in France. As a foreign seller, when you invoice a French company for goods or services, that invoice enters the French tax system — and must comply with France's e-invoicing rules.

You are affected if:

• You sell products or services to French companies (B2B)
• Your French clients are VAT-registered — which most business customers are
• You invoice for any amount, even for intra-EU service contracts

You are not directly affected if:

• You exclusively sell to French consumers (B2C only)
• Your only French transactions involve micro-businesses that have not yet reached their emission deadline (September 2027)

In practice, if your French clients include any medium or large company, you should be ready by September 2026.

The formats you need to know: Factur-X, UBL 2.1, and CII

France accepts three e-invoice formats, all based on open standards and aligned with the European Norm EN 16931.

Factur-X

Factur-X is the Franco-German hybrid PDF/XML standard. The invoice looks like a standard PDF but embeds a structured XML file. It is the most widely used format in France and is the default output of virtually all French accounting software. For foreign businesses targeting French clients, Factur-X at the EN 16931 (Comfort) or EXTENDED conformance level is the recommended choice.

UBL 2.1 (Universal Business Language)

UBL is a global XML standard already widely used in Spain, the Netherlands, the UK, and across the EU. If your ERP or accounting system already generates UBL 2.1 invoices — for example through Peppol — France's PPF and PDP platforms accept them directly. No format conversion required.

CII (Cross Industry Invoice)

The UN/CEFACT Cross Industry Invoice format is also accepted by France. CII is actually the XML backbone embedded inside every Factur-X file. If your system outputs standalone CII XML, it is valid — provided it conforms to EN 16931.

Key compliance requirements for foreign invoicers

Beyond format, invoices sent to French companies must carry specific mandatory fields. Missing any one of them can lead to rejection by the receiving platform or, worse, a tax audit.

Mandatory fields on every invoice

• Your company name and full registered address
• Your VAT identification number
• Your French client's SIRET number (14-digit French business identifier)
• Your French client's intra-community VAT number
• A unique, sequential invoice number
• Invoice date and payment due date
• Clear description of goods or services delivered
• Unit price, quantity, and line totals
• Applicable tax rate (or reverse charge mention)
• Total amounts: excl. VAT, VAT amount, and incl. VAT
• Payment terms and late-payment penalty rate

The reverse charge for intra-EU B2B supplies

If you are supplying services or goods from within the EU to a French VAT-registered company, the reverse charge mechanism typically applies. Your invoice should state “Autoliquidation de la TVA par le preneur” (or “VAT reverse-charged to recipient” in English), show a 0% VAT rate, and indicate the legal basis. Your French client self-reports the VAT on their end.

Transmission through a certified platform

From September 2026, invoices cannot simply be emailed as PDF attachments. They must be routed through one of two channels:

• A PDP (Plateforme de Dématérialisation Partenaire) — a private platform accredited by the French tax authority (DGFIP)
• The PPF(Portail Public de Facturation) — France's official government portal

Bonne Facture routes your invoices through an accredited PDP automatically.

Timeline: when do the rules kick in?

The reform rolls out in two waves, based on the size of your French client:

What this means for you as a foreign supplier:

From September 1, 2026, if your French client is a large company or an ETI, they will expect compliant e-invoices routed through an accredited channel. Sending a standalone PDF by email may be rejected outright — or at minimum, not processed correctly.

Even for smaller French SME clients, they can receive compliant e-invoices from September 2026 and many will actively request it to streamline their own accounting.

Our recommendation: don't wait until September 2026. Configuring and testing your invoicing stack takes time. Start today so you're not scrambling when large clients start rejecting non-compliant invoices.

How Bonne Facture handles it for you automatically

Bonne Facture was designed with international sellers in mind. If you're a German GmbH, a UK Ltd, a Spanish SL, an Italian SRL, or a Dutch BV invoicing French clients, here is what the platform handles for you — with no manual configuration required.

1. Automatic Factur-X generation

Enter your invoice data once. Bonne Facture generates a compliant Factur-X PDF/XML hybrid at the EN 16931 conformance level — the format most widely accepted across French companies and certified platforms. You download a single file that is both human-readable and machine-processable.

2. Mandatory field validation

Before you confirm any invoice, Bonne Facture checks that all required French fields are present: SIRET number, TVA intracommunautaire, payment terms, and mandatory mentions for reverse-charge transactions. Missing fields are flagged before sending — not discovered after rejection.

3. Multi-currency and reverse-charge support

Invoice in EUR, GBP, USD, or any major currency. Bonne Facture applies the correct reverse-charge mention automatically for intra-EU B2B transactions, so your invoices are always legally correct for French VAT purposes.

4. PDP routing from September 2026

When the transmission mandate goes live, your invoices are routed through an accredited PDP automatically — no account setup on multiple platforms, no manual submission. Bonne Facture manages the entire delivery workflow.

5. 10-year compliant archiving

French tax law requires e-invoices to be archived for a minimum of 10 years. Bonne Facture stores all your invoices in certified long-term storage, accessible and downloadable at any time — even if you change software providers.

6. Bilingual invoice templates

Your French clients receive a document they can read; your own accounting team sees the version they need. Bonne Facture supports bilingual templates so you never compromise between your language and your client's expectations.

Bottom line: compliance is a process, not a one-day task

France's 2026 e-invoicing reform is not a distant risk for foreign businesses — it is a concrete change in how invoices must be structured and transmitted, and it affects you the moment your French client becomes legally required to receive compliant invoices.

The requirements are well-defined, the deadlines are known, and the technology to comply already exists. You do not need to become an expert in Factur-X or PDP networks. You need a solution that handles it in the background while you focus on selling.

Bonne Facture makes French e-invoicing compliance invisible — so you can keep doing business across borders without worrying about formats, platforms, or regulations.
