Mandatory E-Invoicing 2026-2027: the Freelancer's Guide

E-invoicing becomes mandatory: what's coming

France is generalising electronic invoicing between businesses (B2B). It's no longer optional: it's a legal obligation rolling out in two phases. The government's goal is to fight VAT fraud and simplify reporting.

For a freelancer or self-employed worker, it's better to understand the timeline now than to rush at the last minute.

The timeline to remember

1 September 2026 : all businesses, whatever their size, must be able to receive an electronic invoice. Large companies and mid-caps must also start issuing them.

1 September 2027 : the obligation to issue electronic invoices extends to SMEs and small businesses.

In other words: from autumn 2026, you must be able to receive invoices in electronic format. And you have until late 2027 to issue your own properly.

What is a “real” electronic invoice?

Beware the trap: a PDF sent by email is not an electronic invoice under the reform. A compliant e-invoice is:

a structured format readable by machines: Factur-X (PDF + XML data), UBL or CII;

transmitted via a government-approved platform (not just email).

These formats let the tax authority and your clients process the invoice automatically, without re-keying.

What it concretely changes for you

You must choose a compliant tool

Spreadsheets and homemade PDFs won't cut it anymore. You need software able to generate the right format and transmit via an approved platform. Good news: it's seamless once the tool is in place.

Even VAT-exempt, you're concerned

Many micro-entrepreneurs think they're exempt. They're not: the reform applies to all businesses, including VAT-exempt ones.

Anticipating means avoiding stress

Switching tools in a rush, weeks before the deadline, is the surest way to make mistakes. Choosing a solution that follows the timeline today keeps you safe.
