E-Invoicing: Learnings from France

Drawing on two OpinionWay surveys commissioned by Quadient and the first official figures from France, we share six lessons and what they mean for you.

Six lessons from France's e-invoicing mandate

1. Knowing the e-invoicing mandate isn't the same as being ready for it

Imagine you've passed the written portion of your driver's test, and tomorrow you're merging onto the freeway for the first time. That's roughly where many French companies stood in early 2026: nine in ten knew the law, yet only 7% met all the requirements set by the tax authorities.

In Germany, only 6% of companies consider the key operational requirements complete.

What this means for you:

• Take stock: Review your invoice types, mandatory data fields, validation, and archiving against concrete criteria.

• Set your KPIs: Start measuring processing times, rejection rates, backlog, and the share of invoices that go through without manual touchpoints. That way, you'll see exactly what e-invoicing delivers.

2. Master data and tax codes are the real e-invoicing project

Many French companies assumed technology would be the biggest hurdle. In reality, the problems were in the data: incomplete master data, inconsistent tax codes, and far more special cases than expected, such as down payment invoices or invoices paid by a third party.

These errors have a domino effect. One wrong VAT ID gets the invoice rejected, the payment is delayed, and your team has to rework it.

What this means for you:

• Involve business teams early: Accounting, procurement, and sales know your invoice types and where the data falls short.

• Clean up your master data: Fix outdated or duplicate customer and supplier records before go-live.

• Check mandatory fields: A file with format errors doesn't count as an e-invoice under German tax rules. Which data goes where is defined in the German Federal Ministry of Finance's guidance of October 15, 2026.

3. PDF, paper, e-invoice: Why your inbound invoices will stay mixed for now

An e-invoicing mandate doesn't make PDF and paper disappear overnight. In France, both still dominated in early 2026, and only one in five companies used a compliant format. New formats get added rather than replacing the old ones.

In Germany, too, PDF remains the most common way to send invoices. On top of that, suppliers with prior-year revenue of up to €800,000 may still send paper invoices in 2027, and PDFs if the recipient agrees.

What this means for you:

• Plan for mixed inbound invoices: Through the end of 2027, your processes need to handle e-invoices, PDFs, and paper side by side.

• Assign responsibility: Decide who checks whether a PDF is still permitted. Otherwise, you risk losing your input VAT deduction.

4. E-invoicing doesn't work without your customers and suppliers

An e-invoice is only as good as the process on the other end. French companies that had already made the switch said their biggest hurdle wasn't their own IT. It was their business partners, especially customers who didn't yet meet the standards.

Many also worry that losing the familiar invoice look will weaken their personal connection with customers and suppliers. Our e-book “The E-Invoicing Hurdle Race” shows how to clear this and other hurdles: [Link to e-book].

What this means for you:

• Align early: Agree with key customers and suppliers in 2026 on how you'll exchange e-invoices.

• Keep customers informed: If your revenue exceeds €800,000, let your customers know. They need this information to secure their input VAT deduction.

• Keep your invoice look: With the hybrid ZUGFeRD format, you send structured data and still keep your familiar layout. Your invoice remains your company's calling card.

5. Choose your e-invoicing provider early: The rush comes right before the deadline

In early 2026, about a third of French companies hadn't yet chosen a platform. Of those, only 13% planned to sign by April, while almost half planned to wait until July or August. Three weeks after the deadline, more than a quarter of the core target group still had no platform.

The real work only starts after you choose a platform: ERP integration, testing with real invoices, and training. When everyone starts at once, provider capacity gets tight and testing gets cut short. That's why France is waiving penalties in 2026 for companies that can show a serious transition effort.

What this means for you:

• Don't count on a delay: In October 2026, Germany's Federal Ministry of Finance confirmed the timeline stands.

• Build in time for testing: Start now, and you can test without pressure and go into January 1, 2027 well prepared.

6. After e-invoicing comes Germany's 2030 reporting system

E-invoicing is just the foundation. In France, the areas furthest behind were e-reporting and invoice status updates, the topics that go beyond the format itself. And in both countries, companies name cyber risk as their top concern.

Germany is planning its next step too. In September 2026, the Federal Ministry of Finance presented its roadmap for a digital VAT reporting system at the German e-invoicing association (VeR): legislation from 2027, a pilot phase from 2029, and mandatory reporting from July 1, 2030.

What this means for you:

• Skip the stopgap: Emailing XML files without status tracking is something you'd have to replace by 2030 at the latest.

• Build for the future: Rely on structured data flows, status tracking, and secure channels like Peppol. Then the reporting system becomes an extension, not a new project.

The bottom line

France shows that e-invoicing mandates rarely fail because of technology. They stumble on data, partners, and time.

Half of French companies see the mandate as both useful and burdensome. Both are true. If you invest in clean data and processes now, you'll benefit from fewer errors and faster workflows. And if you plan your transition with the 2030 reporting system in mind, you'll only have to make the journey once.
