The verdict in three sentences
The e-invoicing reform makes receiving electronic invoices mandatory for all French companies from September 2026, with issuing following by company size. Connecting to a PDP (partner dematerialisation platform) and adapting your IT system costs EUR 5,000 to 30,000 depending on formats (Factur-X, UBL, CII) and e-reporting flows. Acting early avoids penalties and the vendor bottleneck at the end of the timeline.
2026 timeline and scope
The timeline separates the receiving obligation (universal) from the issuing obligation (phased by size).
| Deadline | Obligation | Companies affected |
|---|---|---|
| Sep. 2026 | Receiving e-invoices | All |
| Sep. 2026 | Issuing | Large companies and mid-caps |
| Sep. 2027 | Issuing | SMEs, small firms, micro |
| Ongoing | E-reporting (B2C, cross-border) | All, by transaction type |
| Ongoing | Invoice lifecycle statuses | All |
Official dates may be adjusted: confirm with your accountant or the tax authority.
What compliance costs
The budget mostly depends on your existing system: a modern billing tool, an ERP to connect, or manual entry to equip.
| Starting situation | Integration work | Price 2026 (EUR) |
|---|---|---|
| PDP-compatible software | Setup, testing | 1,500 - 5,000 |
| ERP to connect to a PDP | Connector, Factur-X mapping | 5,000 - 15,000 |
| Heterogeneous multi-flow IT | Integration, e-reporting | 15,000 - 30,000 |
| PDP subscription | Per flow/invoice | EUR 0.10 - 0.50/invoice |
| Format/API maintenance | Regulatory changes | 10-15 %/yr |
Mini case study
Sophie, CFO of a 60-person services SME in Nantes, issues 900 invoices/month from an ERP with no PDP connector. She picks a PDP and commissions a Factur-X connector at EUR 12,000, plus EUR 0.25/invoice (EUR 225/month). In return she removes printing and postal mailing (estimated EUR 1.80/invoice, EUR 1,620/month) and cuts reconciliation disputes. Net savings exceed EUR 1,300/month from go-live: the connector pays for itself in under ten months, compliance included.

What is a PDP and do I need one?
A PDP is an accredited partner dematerialisation platform authorised to issue, transmit and receive electronic invoices. Choosing a PDP is the recommended route for most companies with meaningful volume.
Which invoice formats are accepted?
The core formats are Factur-X (PDF + XML), UBL and CII. Factur-X is the most common because it is both human- and machine-readable.
What is the penalty for non-compliance?
Penalties apply per non-compliant invoice and per e-reporting failure, capped annually. Beyond the fine, the risk is operational: being unable to invoice your customers.
Will my current software be enough?
If your vendor becomes a PDP or interfaces with one, simple configuration (EUR 1,500-5,000) may suffice. A closed ERP will need a connector.
When should I start the project?
Now: vendors and PDPs will be saturated near the deadlines. A project launched 6 to 9 months before the obligation stays comfortable.
