NF525 compliant invoice

Concretely, what does the NF525 standard require from invoicing software?

It rests on four core principles: data inalterability, security, retention and archiving of invoices and payments. Bizyness applies these requirements by default, with no setup on your part.
Can I edit or delete an invoice I've already issued?

No, and that's precisely the principle of inalterability: a validated invoice can no longer be modified or erased. To correct it, you issue a credit note, which Bizyness generates automatically while keeping the full audit trail.
Is my invoice numbering secure?

Yes. Bizyness assigns continuous, chronological numbering with no gaps, as the regulations require. You avoid any risk of a missing number or a duplicate in your invoice sequence.

Does the NF525 standard also apply to my invoices generated from Shopify, Stripe or Amazon?

Yes. Whether an invoice comes from manual entry or from a synced online sale, it is subject to the same inalterability and security requirements. Bizyness applies them the same way to all your invoices, whatever their source.
Is complying with NF525 enough to be ready for 2026 e-invoicing?

It's an essential building block, the security and inalterability of your invoices, but the 2026 reform also adds transmission via a PDP and e-reporting. Bizyness covers the whole scope: compliant invoicing, transmission through a PDP partner and e-reporting.
Where are my invoices hosted and stored?

Your data is hosted in Europe and securely archived for the legal retention period. You keep permanent access to it and can export it at any time, in particular in the event of an audit.

Your invoices meet NF525 requirements: tamper-proof, timestamped and ready for an audit.
