NF525 secures invoices and payments; NF203 goes further by targeting the reliability and probative-value archiving of all your accounting data. The two complement each other to cover the whole chain, from invoice to accounting entry.
It means your accounting documents are kept in a way that lets them stand up to the tax authorities in the event of an audit: intact, time-stamped and tamper-proof. That's the level of reliability NF203 targets.
Your entries and supporting documents are archived for the legal retention period, i.e. 10 years, with no action required from you. They remain accessible and exportable at any time.
Yes. Every operation (syncing an order, generating an invoice, running an accounting export) is time-stamped and recorded in a tamper-proof event log. You have a complete audit trail, whatever the source of the sale.
No. NF203 requirements mandate security, backup and redundancy mechanisms. Your data stays available and protected against loss, alteration and unauthorized access.
Yes. That's the whole point of the probative value NF203 targets: your entries and documents are archived in an intact, time-stamped and tamper-proof way, so they can be produced to the authorities. You can present and export them at any time during an audit.
Bizyness secures and archives your data in line with NF203 requirements, for integrity guaranteed over time.
