Frequently asked questions

Is certification mandatory?

Since February 2025, certification has become mandatory for all point-of-sale software used by professionals subject to VAT in France.

This certification aims to ensure that cash systems comply with strict requirements regarding:

Data Immutability

Preventing the modification or deletion of recorded sales data.

Data Security

Ensuring data integrity through technical mechanisms such as hashing and digital signatures.

Data Retention

Storing data in a readable, accessible, and durable manner for the legally required period.

Data Archiving

Freezing periodic closure data with traceability for later retrieval.

What are the penalties?

Penalties apply both to the taxable person who does not use certified point-of-sale software, and to the software vendor if the solution is found to be permissive.

The taxable person

  • A fine of €7,500 applies for each non-compliant software solution
  • A 60-day window is granted to bring the software into compliance
  • Failure to comply within the 60-day period results in an additional fine

The software vendor

  • In some cases, a €10,000 fine may apply for each software license sold
  • A fine of €37,500 and up to 5 years in prison for complicity in tax fraud

What are the deadlines for becoming compliant?

The law provides for a transitional period allowing software vendors and users to bring their systems into compliance:

February 16, 2025
  • Certificate of compliance
  • Software vendor’s attestation
  • Proof of engagement in the certification process
September 1st, 2025
  • Certificate of compliance
  • Proof of engagement
March 1st, 2026

Only the certificate of compliance will be accepted

My software does not handle cash registers; am I subject to the requirements?

It depends.

If your software records payments or manages invoicing or payment modules, you may be concerned even if it’s not a traditional cash register.

A technical audit is recommended to assess your exposure to the certification requirement.

What is the difference between NF525 and LNE certification?

The approaches are different:

INFOCERT

Proposes a single standard, NF525, applicable to all point-of-sale software.

In other words, INFOCERT does not check whether you comply with the law, but whether you have correctly implemented the NF525 requirements.

The response to legal requirements is clear and unique.

LNE

Is based solely on legal requirements.

The LNE has a framework providing initial responses to legal requirements, but the software vendor is free to propose their own solutions.

The LNE will assess whether your customized response to legal requirements is reliable.

In summary, the INFOCERT solution is more restrictive than that of the LNE, which remains somewhat more subjective.

Both solutions are, however, equivalent under the law.

What is the validity period of a certification?

Certifications are valid for 3 years, with an annual renewal audit to ensure ongoing compliance.

How much does certification cost?

As of August 5, 2025, the certification costs for both organizations are equivalent.

You should budget €15,000 for the initial audit and between €4,000 and €6,000 for the renewal audits.

Is it possible to get certified without support?

Yes. A software vendor can obtain certification on their own without requiring external support.

However, support helps optimize your compliance process. The consultant guides you throughout, ensuring your efforts are on the right track.

The NF525 requirements, or legal requirements, remain somewhat generic and vague, leaving room for errors during implementation. A consultant has the necessary perspective to help you adapt these requirements according to your technical and business specifics.

There is a right to make mistakes. A non-compliant audit is not final. However, it leads to additional costs that can be avoided with proper support.
