What to know about e-invoicing in France

Updated 1 September 2026

The French mandate is now live. Every business established in France must be able to receive electronic invoices through an approved platform (plateforme agréée) from 1 September 2026. Large and mid-size companies must also issue from that date; freelancers, small studios and micro-entreprises issue from 1 September 2027. If you invoice French clients from outside France, the mandate does not apply to you at all.

What matters for you as a freelancer

• ✓Agency OS already produces a compliant invoice for this country today — no extra setup needed on your side.
• ✓If your client asks for an e-invoice, you can send one immediately.
• ✓Keep an eye on the mandate date above — it determines when e-invoicing becomes mandatory rather than optional for domestic B2B.

What you don't need to worry about

• –You don't need to change your invoicing workflow ahead of the mandate — Agency OS already outputs the required format.
• –Cross-border invoices to clients in other countries aren't affected by this country's domestic mandate.

What must be on a valid B2B invoice

• ·Your SIREN/SIRET, legal form, and full address
• ·Client's name and address
• ·Invoice date and a unique, sequential invoice number
• ·Description and quantity of goods or services
• ·Unit price excluding VAT, and any discounts
• ·VAT rate and amount — or the exemption/reverse-charge wording
• ·Total amount due, payment terms, and late-payment penalty terms
