What is mandatory electronic invoicing?

Electronic invoicing (or e-invoicing) refers to the issuance, transmission, and receipt of invoices in a structured, machine-readable format (XML, UBL, CII, Factur-X), via a PDP platform (Partner Dematerialization Platform) or PA (Approved Platform). Unlike a simple PDF, e-invoicing enables complete automation: automatic information extraction, direct accounting in the ERP, and data transmission to tax authorities.

Important: A PDF alone does not constitute an electronic invoice under French reform requirements.

E-Invoicing and e-reporting: two obligations

The French reform distinguishes two complementary obligations. E-invoicing concerns the issuance and receipt of B2B invoices in structured format via approved platforms. E-reporting requires automatic transmission of transaction data to the DGFiP (French tax authority) for international B2B and B2C operations.

Why the September 2026 reform? (after 3 delays)

After several delays of electronic invoicing (initially planned for 2023, then 2024), the 2026-2027 timeline is now final. The government pursues four main objectives with this reform: fighting VAT fraud (estimated at several billion euros in annual revenue loss), modernizing business invoicing processes, accelerating digital transformation of the French economy, and harmonizing with Europe in anticipation of the ViDA directive planned for 2030.

Electronic invoicing calendar 2026-2027: key dates by business type

September 1st, 2026 (wave 1): Large companies and mid-caps

This first wave concerns large enterprises (more than 5,000 employees or turnover exceeding €1.5 billion) as well as mid-sized companies (250 to 5,000 employees). These organizations must simultaneously ensure B2B electronic invoice issuance and reception, while transmitting their data via e-reporting to the DGFiP.

Critical point: As of September 2026, ALL companies must be able to receive electronic invoices.

September 1st, 2027 (wave 2): SMEs, micro-enterprises, self-employed

The second wave applies to SMEs (less than 250 employees), micro-enterprises (less than 10 employees), as well as self-employed and sole proprietors. These organizations must manage their B2B electronic invoice issuance and transmit their data via e-reporting to the DGFiP.

Today: preparation phase

Integration projects require 4 to 6 months. To be ready by September 2026, you need to act now by choosing a certified Approved Platform (PA), integrating your ERP with this platform, training your teams, and auditing your customer and supplier data.

The French model: the Y-architecture explained

France has adopted a unique decentralized model in Europe, based on a mixed public-private ecosystem.

The 5 actors in the circuit

1. The issuer: creates the invoice in their ERP
2. The issuing PA/PDP: validates and transmits the invoice
3. The PPF (Public Portal): directory and routing (managed by the DGFiP)
4. The receiving PA: receives and makes the invoice available
5. The recipient: retrieves the invoice in their system

Approved Platform (PA): what is it?

An Approved Platform (or PDP) is an operator certified by the DGFiP for electronic invoicing to manage invoice issuance/reception and ensure interoperability with the PPF and Peppol.

Examples: Chorus Pro (free electronic invoicing, public platform), Invopop, Pagero, Basware.

6 steps to prepare your e-invoicing compliance

Step 1: ERP compliance audit

This first step involves assessing whether your ERP supports structured formats (XML, Factur-X), verifying that your customer data is complete (SIREN, Peppol IDs), and estimating your monthly volume of invoices issued and received.

Step 2: Target architecture

You'll need to define which approved platform to choose, opt for native integration or via middleware, and decide between full automation or manual validation according to your internal processes.

Step 3: Platform connection

This technical step includes API or ERP connector configuration, invoice field mapping to ensure format compatibility, and transmission tests to validate proper flow operation.

Step 4: AR/AP setup

The AR flow (issuance) automates e-invoice generation, their transmission via the approved platform, and status synchronization (Issued, Received, Paid) for real-time tracking.

The AP flow (reception) centralizes incoming invoice reception in a unified inbox, enables automatic matching with purchase orders, and integrates an approval workflow adapted to your organization.

Step 5: Testing and training

This 4 to 6-week phase combines UAT testing on real scenarios, training your teams on new processes, and a pilot with selected customers and suppliers to validate system operability.

Step 6: Go-live

Deployment comes with internal and external communication to all stakeholders, reinforced support during the first 2 to 4 weeks, and continuous monitoring of success rates to quickly identify and correct any issues.

FAQ: your questions about the reform

1. What is the mandatory electronic invoicing date for my business?

E-invoicing is mandatory for all businesses, but the reform date varies according to your size:

• September 1st, 2026: Large companies and mid-caps (issuance + reception)
• September 1st, 2027: SMEs, micro-enterprises, self-employed (issuance)
• From September 2026: ALL companies must be able to receive e-invoices

2. Can I continue to send PDFs?

No. PDFs will no longer be compliant for B2B transactions from your obligation date. You must use a structured format via an approved platform.

3. What is the cost of electronic invoicing?

The cost of this obligation for an SME varies according to your configuration. Expect between €20 and €200/month for the approved platform, an initial investment of €2,000 to €10,000 for ERP integration, and €1,000 to €5,000 for team training. In total, the initial investment is between €10,000 and €30,000, plus recurring fees of €50 to €150/month.

4. What happens if I'm not compliant?

Non-compliant companies face several sanctions: tax penalties, inability to invoice B2B clients, and payment blocking by approved platforms. Non-compliance can therefore paralyze your business activity.

5. Is my NetSuite ERP compatible with French electronic invoicing?

Yes. NetSuite can be integrated with an approved platform (PA/PDP) via API or native connector.

6. What is the difference between PA, PDP, and PPF?

• PPF: free public platform from the DGFiP (routing and directory)
• PDP: certified private operator managing your invoicing flows (issuance, reception, automation)
• PA: former term for PDP

The PPF is mandatory for all. A PDP is recommended if you want to automate your processes and integrate with your NetSuite ERP.

7. Is Chorus Pro sufficient for my business?

Chorus Pro (public PPF) is free for micro-enterprises/SMEs, but may require a PDP for advanced automation.
