Under the French e-invoicing reform, all companies in France will progressively have to issue and receive their invoices in electronic format. The transition officially starts in September 2026. It upends administrative habits, and it also opens the way to smoother, more automated tax management.

Understanding the 2026 e-invoicing reform
The 2026 reform of electronic invoicing is part of the modernisation plan for French VAT. It pursues two goals: reduce fraud and simplify exchanges between businesses. From September 2026, every company must be able to issue structured electronic invoices that meet the requirements of Article 289 of the French General Tax Code (CGI).
Unlike plain PDF invoices, electronic invoices must contain structured data allowing the tax administration’s systems and commercial partners to read and process them automatically.
Key point. The reform aims to generalise the exchange of structured, secured invoices, and to automate VAT declaration through the direct transmission of data to the administration.
Who is concerned, and on what calendar
Deployment is staggered by company size. Companies must both be able to issue invoices (e-invoicing) and transmit their transaction data (e-reporting).
Receiving electronic invoices becomes mandatory for all companies in September 2026. Issuing phases in afterwards, by company size.
Which invoice formats are allowed
The formats recognised by the reform are called structured: Factur-X, UBL and CII. They let the invoice data flow directly into accounting systems or the administration’s interface.
Factur-X: the hybrid standard
Factur-X combines a human-readable PDF with a normalised XML file. It supports human review while enabling automated processing.
UBL and CII: the international standards
These purely structured formats are already used in many international flows. Their adoption depends on how deeply the company is integrated into complex digital supply chains.
Watch out. A plain unstructured PDF or a scanned invoice will no longer be considered compliant. Companies should check their tooling now.
PPF, PDP, OD: how the ecosystem fits together
Practical implementation rests on three kinds of actors:
- PPF: the Public Invoicing Portal (built on Chorus Pro), which centralises exchanges with the tax administration.
- PDP: Partner Dematerialisation Platforms, certified to transmit invoices in compliance.
- OD: Dematerialisation Operators, who help companies collect, convert and manage their invoices.
Each company will choose which platform carries its electronic invoices.
Good reflex. Check that your software or provider can connect to a certified PDP. Services like e-invoicing.fr can also act as your mandatory agent (art. 1984 French Civil Code) to recover compliant invoices from your suppliers.
Practical case: a mid-size company in Lyon
Atelier Desplanches, a 38-person furniture maker working for the hospitality industry, generates €6 million in revenue. In 2024 its finance director started preparing for the 2026 transition.
The initial difficulties
The company issued PDF invoices from an ERP not connected to any portal. Suppliers sometimes sent non-compliant invoices, slowing down VAT recovery.
The transition
Working with an accountant and the e-invoicing.fr service, Atelier Desplanches mandated the platform to collect invoices automatically from its merchants and suppliers: carriers, hardware dealers, printers.
The results
Within six months, document recovery times were halved, compliance improved, and cash visibility increased. The company is now ready for the later issuance deadlines.
Legal obligations
Article L441-9 of the French Commercial Code has required an invoice for every sale of goods or service between professionals since 2019. The e-invoicing reform does not change the principle: it digitises the medium and strengthens traceability.
Articles 286 and 289 of the CGI specify the mandatory content of invoices, in particular the details supporting VAT deduction. Every electronic invoice must guarantee the authenticity of origin, the integrity of content and legibility.
Acting through a mandatory agent, under Article 1984 of the Civil Code, lets a company delegate invoice recovery and follow-up to a third party, under its responsibility. That is the legal basis on which e-invoicing.fr operates.
Good to know. Tax audits will be able to use platform data directly to check the consistency between declared sales and issued invoices. Keep your customer and supplier directories up to date.

Frequently asked questions
Does an electronic invoice have the same value as a paper one?
Yes. When it meets the requirements of Articles 289 and 289 bis of the CGI, it has the same legal value as a paper invoice, and the administration accepts digital archiving.
What happens if a supplier refuses to issue an electronic invoice in 2026?
The company must flag it and request a compliant invoice. Failing that, the document will not support VAT recovery. A mandated third party simplifies these steps.
Can I keep sending PDF invoices to my consumer customers?
Yes. The reform only concerns exchanges between VAT-registered businesses (domestic B2B). For consumers, current rules continue to apply.
