E-invoicing: eKo CRM is ready to support you!
E-invoicing is gradually becoming mandatory for businesses in France and Luxembourg.
eKo is ready for e-invoicing
To simplify the management of your legal obligations, eKo CRM builds e-invoicing directly into its CRM, centralising all your transactions in a single tool. E-invoicing is a real challenge for businesses, with new obligations. The reform, being phased in gradually in France and already in force in certain sectors in Luxembourg, aims to improve the transparency, traceability and efficiency of exchanges between businesses and public authorities (and to prevent tax fraud).

What is e-invoicing?
E-invoicing relies on standardised formats and secure protocols. A compliant e-invoice must:
- Be transmitted in a standardised structured format, such as UBL, Factur-X or CII;
- Go through a certified e-invoicing platform (PA);
- Meet the legal requirements for content and traceability. Simple PDFs sent by email are not considered compliant e-invoices.
The aim is to guarantee the integrity, authenticity and legibility of e-invoices throughout their life cycle, from the supplier to the customer and on to the tax authorities.
Types of obligations by transaction
Type of transaction |
Mandatory since |
Description |
|---|---|---|
| B2G (Business to Government) | 2020 | Invoicing public authorities via Chorus Pro. Mandatory for all businesses invoicing the public sector. |
| B2B (Business to Business) | 2026-2027 | Gradual obligation for all VAT-registered businesses. Invoices must use structured formats and be transmitted via a PA. |
| B2C (Business to Consumer) | N/A | Conventional invoices (PDF) are still possible, but e-reporting of sales is mandatory. |
Mandatory information to include in e-invoices
From September 2026, certain information must appear on e-invoices:
- The customer's SIREN number (French company registration number);
- Category of the transaction (sale of goods, provision of services, etc.);
- Indication of the option to pay VAT on debits, if applicable;
- Full delivery address if different from the billing address.
Platforms and solutions for France
Businesses will have to choose a certified e-invoicing platform (PA) to issue and receive e-invoices. The official list of certified platforms is available on the French tax authorities' website. Using a PA guarantees legal compliance and secure exchanges.
