NF525 tax compliance at the service of your business
The certification NF525 This becomes a major issue as tax regulations evolve in France. MedialogWe are anticipating these changes to allow you to focus on what matters most: the restaurant.
We are pleased to announce that Medialog Restaurant and our entire POS suite are now NF525 certified by INFOCERT (Certificate No. 525/0688-1). This certification is effective from the version 9.x, our certified major version.
Why is this a crucial step?
- Finance Law 2025 The rules are getting stricter to combat VAT fraud.
- Certification vs. Attestation Unlike a simple publisher's certificate, NF525 is a validation by a trusted third party.
- Total serenity A rigorous structure to guarantee perfection in the event of a tax audit.
Faced with administrative requirements, your point-of-sale software becomes your best legal ally.
The 4 pillars of the ISCA standard
To comply with the requirements of the official gazette BOI-TVA-DECLA-30-10-30Medialog guarantees four fundamental conditions:
Unalterability Once validated, a ticket cannot be modified or deleted. Even the generation of a provisional note is saved.
Securing : Each important transaction and event is "sealed" in the database by a unique electronic signature.
Conservation : All operations are tracked chronologically in the Technical Event Log (JET).
Archiving The data is kept for a minimum of 6 years in a secure tax archive and can be retrieved at any time.
The NF525 certification, issued by INFOCERT, is the benchmark for compliance for VAT-registered businesses in France. It proves that the software meets the strictest reliability criteria.
What's changing on your POS (Version 9.x)
The transition to the NF525 standard introduces major changes in the management of your supporting documents:
New nomenclature Each document has its own prefix and chained number (e.g., TCK- for the tickets, FAC- for invoices, NOTE- (for the notes).
Print management In accordance with the 2023 anti-waste law, automatic printing is prohibited. An action popup appears at the end of the process.
VAT is prohibited on invoices : It is now strictly forbidden to display the VAT calculation on provisional invoices (before payment).
Traceability of duplicates : Any duplicate receipt or ticket must now be justified and recorded in the system.
The JET: Your institution's "Black Box"
Le Technical Events Log (JET) is a chronological log that records all significant events in your software's lifecycle.
The real question is: Is your current system ready to justify every action?
Monitoring of sensitive operations
The JET records session openings, abandonments of commercial transactions not yet recorded, and changes to the "offered" note.
Automatic Tax Archive
The tax archive is a secure file (.zip) containing all your cash register data. It is automatically generated at the end of each calendar year. You can access it directly from your management portal.
Mandatory periodic closures
To guarantee the integrity of the "Grand Totals," the system requires the recording of daily, monthly, and annual closing entries. User intervention is not required: these operations are automated and stored in the database.
Are you affected by NF525?
Three criteria can be used to determine whether your institution should use certified software:
- ✓ You collect VAT.
- ✓ You collect payments from individuals and professionals.
- ✓ You are using a point-of-sale (POS) solution.
❌ Important note Establishments located outside of France are not subject to this requirement. The "NF525" parameter is therefore not activated, freeing the software from these specific constraints.
✔ For French establishments Medialog version 9.x automatically activates these security measures to protect you.
Conclusion
The certification NF525 It's not just an administrative constraint; it's a guarantee of transparency and modernity.
