What a business in Paris has to get right
Paris firms sell to buyers who read the legal pages. French business sites need mentions légales and a cookie banner that meets the CNIL's rules; the CNIL is the data-protection authority. Receiving e-invoices became mandatory on 1 September 2026, and issuing them is phased in from 2026 to 2027 by company size.
