Stay compliant
without the overhead.
A good register should not be a burden. Lympide handles the NF525 requirements (French anti-fraud VAT law), cash drawer management, end-of-day closures, and accounting exports automatically — so your records stay clean without extra effort.
A clean register means clean accounting.
One less thing to worry about
Compliance is a mental burden for business owners. Lympide handles it continuously — no special migration, no manual workarounds.
Clean data from receipt to balance sheet
Register, inventory, and reporting share a single data source. Your accountant gets consistent figures with no intermediate spreadsheets.
Audit-ready at any time
Audit log, legal archiving, FEC (Fichier des Ecritures Comptables) exports: everything required for a tax audit is already there, structured and readable.
Three topics. One single data source.
NF525, cash drawer management, and accounting exports are interconnected. Lympide maintains all three together so none falls short.

The 4 requirements of NF525.
Lympide implements the four principles — Tamper-proofing (Inaltérabilité), Security (Sécurisation), Retention (Conservation), Archiving (Archivage) — at the core of the register.
Tamper-proofing
Each receipt is sealed with a SHA-256 hash chained to the previous one: any alteration breaks the chain.
Security
PIN authentication, audit log of sensitive actions, daily encrypted backups.
Retention
Data retained for 6 years, accessible at any time for tax authorities.
Archiving
Signed monthly archives, exportable, securely hosted and backed up off-site.
Lympide implements the technical requirements of the NF525 standard and issues the publisher's individual attestation provided for by Article 286-I-3° bis of the French Tax Code. The software is not certified by an accredited body. NF525 compliance details
