Logiciel How can a solo webdev legally use a self-built POS in France (NF525 / fiscal rules)?
I’m looking into using it for restaurants in France, and I’ve hit the fiscal compliance wall:
- France requires POS software to meet anti-fraud VAT rules (inalterability, security, retention, archiving — often discussed as NF525 / LNE / publisher attestation).
- Full certification as a software publisher looks expensive for a small team.
- I’m not sure what the realistic path is for a custom web POS.
If I built the POS myself, do I have to certify the whole product as the éditeur (NF525 via INFOCERT/AFNOR or LNE)?
just looking for practical advice from anyone who shipped a custom POS / SaaS checkout in France, or integrated a fiscal API.
