No — as of 20 February 2026, certification is no longer mandatory. The law published in the Official Journal permanently removed this obligation.

Although not mandatory, certification remains a quality and fiscal compliance benchmark. It can be a competitive advantage and reassure your clients about the reliability of your software.

Sanctions remain in force. Any point-of-sale software must be either certified or covered by a non-permissiveness declaration issued by the publisher.

For the end user (company): a fine of €7,500 per non-compliant software, with a 60-day period to remedy the situation.

For the publisher: €10,000 per non-compliant licence sold, and up to €37,500 and 5 years' imprisonment for complicity in tax fraud.

These deadlines applied during the mandatory period (now elapsed):

• 16 February 2025 — Certificate, publisher declaration, or proof of commitment.
• 1 September 2025 — Certificate or formalised proof of commitment.
• 1 March 2026 — Only a certificate was accepted.

Since 20 February 2026, the obligation has been removed.

If your software records payments or manages invoicing or settlement modules, you may be affected even without a traditional point-of-sale system. A technical audit is recommended to be certain.

NF525 (INFOCERT) applies a single, strict framework, applied uniformly to all publishers.

LNE is based solely on legal requirements, which allows tailored solutions with a more flexible — though more subjective — approach.

Both certifications are legally equivalent.

NF525 and LNE certifications are valid for 3 years, with a mandatory annual renewal audit.

• Initial audit: approximately €15,000
• Annual renewal audits: €4,000 to €6,000

These amounts may vary depending on the certifying body and the complexity of the software.

Yes, technically. But specialist support optimises the compliance process, reduces implementation errors and avoids the additional costs associated with non-compliant audits.

Yes. We can help you determine whether certification applies to you, and guide you through the entire process if it does.
