Secure your business
with NF525.
Much more than a simple legal obligation, NF525 certification is the foundation of your peace of mind. It guarantees the inalterability of your checkout data and protects you during tax audits, establishing a lasting trust relationship with the administration.

Security requirements, compliance rigor
The essence of the NF525 standard
Introduced to combat VAT fraud, NF525 certification imposes a strict technical framework on checkout software publishers. It doesn't just check features: it audits the very structure of the database.
Choosing a certified solution means choosing transparency. It's the assurance that every transaction is recorded definitively, securely, and traceably, in accordance with the requirements of the French tax administration.
Absolute technical rigor
The standard was established to technically prevent the concealment of revenue. It makes it impossible to use permissive or fraudulent software ("zappers"). Each sales line is digitally sealed.
A universal obligation
Since January 1, 2018, the use of a secure and certified checkout system is mandatory for all VAT-registered entities recording payments from individual customers (B2C), regardless of business size.
Why is compliance critical ?
Beyond the regulatory aspect, certification protects the sustainability of your business. In the event of an audit, the burden of proof is simplified, and your good faith is presumed thanks to your certificate of conformity.
Major financial risk
The fine amounts to €7,500 per non-compliant system. But the real risk is the rejection of accounting, leading to an ex officio tax assessment on reconstructed turnover.
Proof of good faith
The certificate issued by a third-party organization (AFNOR or LNE) is a proof opposable to the administration, considerably simplifying unannounced audits.
Healthy and structured management
The rigor imposed by NF525 offers you a more accurate financial vision and prevents internal manipulation errors.
The 4 Fundamental Pillars
To obtain the precious certificate, the software must validate four strict technical criteria verified during an in-depth audit.
1. Inalterability
Payment data is recorded. Any modification or cancellation must leave an indelible trace via a compensatory entry ("no more eraser" principle).
2. Security
Cryptographic processes (digital signature, chaining) guarantee the origin and integrity of each piece of data recorded in the system.
3. Conservation
The system imposes closures (daily, monthly, annual) to freeze data and structure its conservation over the legal duration (6 years).
4. Archiving
Data is frozen and archived in a standard format, guaranteeing its readability and ease of access for the administration in case of an audit.
