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

Mandatory e-invoicing 2026-2027: timeline, formats (Factur-X, UBL), approved platforms and impact for freelancers. The clear guide.

29 June 20262 min read

In short

  • In France, receiving electronic invoices becomes mandatory for all businesses on 1 September 2026; issuance applies progressively until September 2027 for small businesses.
  • Invoices will have to flow in structured formats (Factur-X, UBL, CII) through government-approved platforms.
  • Choosing a compliant tool now avoids last-minute stress: a tool like Robi follows the timeline and generates documents in the right format.

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.

    How Robi prepares you

    Robi tracks the reform and generates your invoices by the rules. You invoice normally — by voice or in one sentence thanks to the AI invoice — and the tool handles technical compliance. No need to become an XML-format expert.

    In short

    Mandatory e-invoicing is coming: reception from September 2026, issuance by September 2027 for the self-employed. The classic PDF won't be enough — you'll need a structured format via an approved platform. Anticipate by choosing a compliant tool, and you'll go through the transition painlessly.

    Frequently asked questions

    When does e-invoicing become mandatory?+

    In France, all businesses must be able to receive electronic invoices by 1 September 2026. The obligation to issue applies to large companies and mid-caps on that date, then to SMEs and small businesses on 1 September 2027.

    Is a self-employed person affected?+

    Yes. Even when VAT-exempt, small businesses will have to receive and then issue invoices in electronic format via an approved platform, per the 2026-2027 timeline.

    Will a simple PDF invoice be enough?+

    No. A classic PDF is not an electronic invoice under the reform. You need a structured format (Factur-X, UBL or CII) sent via an approved platform. Compliant software handles this for you.
