Rules your software must follow in France

Tax, e-invoicing, data-protection and AI rules that shape an ERP, billing system or AI agent in France. Last reviewed October 2026.

Indirect taxVAT (TVA), standard rate 20%Standard rate 20% with reduced rates of 10%, 5.5% and 2.1%; most companies file monthly CA3 returns (small businesses may use the annual simplified regime). The e-invoicing reform adds new mandatory invoice fields (e.g. SIREN, delivery address, goods/services category) that billing software must capture.
E-invoicingPhasing in · Accredited platforms (plateformes agréées, PA) with Factur-X, UBL or CII; e-reportingSince 1 Sep 2026 all French VAT-registered businesses must be able to receive e-invoices through an accredited platform, and large and mid-size companies (GE/ETI) must issue e-invoices and e-report B2C and cross-border transaction data; SMEs and micro-businesses must issue from 1 Sep 2027. Accepted formats are Factur-X, UBL and CII.
Data protectionGDPR plus the amended Data Protection Act (Loi Informatique et Libertés, Law No. 78-17)GDPR applies directly, supplemented by the amended Data Protection Act (Loi Informatique et Libertés, Law No. 78-17) and supervised by the CNIL; B2B buyers expect an Art. 28 data processing agreement, a sub-processor list and, in practice, EU/EEA hosting or SCC-covered transfers.
AI rulesThe EU AI Act applies directly: prohibited AI practices have been banned since 2 Feb 2025, general-purpose AI model rules apply since 2 Aug 2025 and transparency duties (e.g. chatbot disclosure, AI-content labelling) since 2 Aug 2026, while the Digital Omnibus on AI (in force 27 Jul 2026) moved stand-alone high-risk (Annex III) obligations to 2 Dec 2027 and product-embedded high-risk (Annex I) obligations to 2 Aug 2028; France has given coordination of AI market surveillance to the DGCCRF, working with sector regulators such as the CNIL.
Systems we migrate from or connect toSage, Cegid, EBP, Pennylane, QuickBooks, Odoo, AxonautMasters, ledgers, stock and open balances move across and are reconciled before cutover.
Payment rails for web apps and SaaSCartes Bancaires (CB), SEPA Credit Transfer and Direct Debit, Stripe, Adyen, PayPal
Also worth knowingCompanies must be able to produce a FEC (Fichier des écritures comptables) file on tax audit, and POS or cash software used for consumer sales must meet anti-fraud requirements (e.g. NF525 certification). ERP vendors typically integrate with one or more accredited platforms rather than the tax portal directly.

General information, not legal or tax advice. Rules change, so we confirm current requirements during discovery; your tax adviser should confirm anything that affects filings.

05 — FAQ

Custom software in France: common questions

Do you work with businesses in France?

Yes. Flip Retail is based in Jaipur, India, and works with France businesses remotely. We have no office in France; discovery happens on video calls, you get working software every two weeks, and the engineers who write the code are on the calls.

Can a custom ERP handle VAT and e-invoicing in France?

Yes. Invoicing is built for France's VAT (standard rate 20%). Since 1 Sep 2026 all French VAT-registered businesses must be able to receive e-invoices through an accredited platform, and large and mid-size companies (GE/ETI) must issue e-invoices and e-report B2C and cross-border transaction data; SMEs and micro-businesses must issue from 1 Sep 2027. Accepted formats are Factur-X, UBL and CII. A custom ERP connects to an accredited platform (PA) through its official API or an accredited provider, and we confirm the current requirements in discovery.

How do you handle GDPR?

GDPR applies directly, supplemented by the amended Data Protection Act (Loi Informatique et Libertés, Law No. 78-17) and supervised by the CNIL; B2B buyers expect an Art. 28 data processing agreement, a sub-processor list and, in practice, EU/EEA hosting or SCC-covered transfers. You choose where the system is hosted, access is role-based, and we work on test or masked data during development wherever possible.

Can you migrate us from Sage, Cegid or EBP?

Yes. Masters, ledgers, stock items and opening balances move across and are reconciled with your accountant before cutover, ideally at a year-end or quarter-end.

Are there AI rules we need to follow in France?

The EU AI Act applies directly: prohibited AI practices have been banned since 2 Feb 2025, general-purpose AI model rules apply since 2 Aug 2025 and transparency duties (e.g. chatbot disclosure, AI-content labelling) since 2 Aug 2026, while the Digital Omnibus on AI (in force 27 Jul 2026) moved stand-alone high-risk (Annex III) obligations to 2 Dec 2027 and product-embedded high-risk (Annex I) obligations to 2 Aug 2028; France has given coordination of AI market surveillance to the DGCCRF, working with sector regulators such as the CNIL. We design AI agents with logging, human oversight and clear disclosure from the start, which covers most current requirements.
