Running a small business in France

10 factors that shape how a small business operates here — tax and e-invoicing, payments, labour and licensing — each with its source and the date it was checked.

1. E-invoicing & Tax Compliance

   All French businesses must receive e-invoices from 1 September 2026

   Detail: Since 1 September 2026 all companies must be able to receive electronic invoices, and large and mid-sized companies (GE/ETI) must issue e-invoices and transmit transaction/payment data (e-reporting). SMEs (PME) and micro-enterprises must issue e-invoices and e-report from 1 September 2027.

   Why it makes work harder: Every TPE/PME had to pick a receiving channel this month and will need structured issuance within 12 months; tradespeople invoicing by Word/Excel/PDF must change tools and processes.

2. E-invoicing & Tax Compliance

   Invoices must flow through a plateforme agréée (accredited platform)

   Detail: The DGFiP practical start-up guide (July 2026) states that issuing, transmitting and receiving electronic invoices must be done through an accredited platform (plateforme agreee); failure to issue electronically is fined per invoice (CGI art. 1737) and e-reporting failures fall under CGI art. 1788 D.

   Why it makes work harder: SMBs must connect their invoicing tool to a PA (or use one bundled), adding a new vendor, cost and onboarding step; invoicing software that is not PA-connected becomes a dead end.

3. E-invoicing & Tax Compliance

   EUR 15 per non-compliant invoice penalty (capped EUR 15,000/yr)

   Detail: Cegid's reform calendar (updated 25 August 2026) cites a fine of EUR 15 per invoice not issued electronically, capped at EUR 15,000 per year. The base obligations start 1 September 2026 (reception) and 1 September 2027 (issuance for SMEs).

   Why it makes work harder: High-volume, low-ticket service businesses (dozens of invoices per week) face meaningful cumulative fines if they keep sending PDFs after their issuance date.

4. E-invoicing & Tax Compliance

   VAT: 20% standard with 10%, 5.5% and 2.1% reduced rates

   Detail: France applies 20% standard VAT, 10% (e.g. passenger transport, some works), 5.5% (food, books, some services) and 2.1% (reimbursable drugs, press). A VAT recodification (Ordinance 2025-1247, 17 December 2025) is due to enter into force on 1 September 2026 (PwC, reviewed 24 April 2026).

   Why it makes work harder: Multiple rates within one job (e.g. renovation labour vs materials) make quoting and invoicing error-prone for trades and restaurants.

5. Language & Localisation

   New mandatory invoice mentions (client SIREN, delivery address, operation type)

   Detail: From 1 September 2026 (large/mid-size) and 1 September 2027 (SMEs/micro), invoices must add the client's SIREN number, the delivery address if different, the nature of the operation (goods/services/both) and any VAT-on-debits option. Service-public.fr page updated 11 August 2026.

   Why it makes work harder: Customer records must capture SIREN and site addresses; quote-to-invoice templates must be rebuilt, adding data-collection burden at job booking.

6. Language & Localisation

   Invoices must be written in French

   Detail: economie.gouv.fr (25 February 2026) states invoices must be 'redigee en langue francaise'; another language is allowed only if a certified French translation can be produced on request of the administration.

   Why it makes work harder: Foreign-owned or multilingual SMB tools must produce French-language documents; English-only invoicing software is non-compliant.

7. Late Payment & Credit

   LME payment terms: 60 days max, EUR 40 recovery fee, fines up to EUR 2m

   Detail: B2B payment defaults to 30 days, with negotiated maximums of 60 days from invoice or 45 days end-of-month. Late penalties apply automatically (minimum 3x legal rate; recommended ECB rate +10 points = 12.40% for H2 2026) plus a EUR 40 flat recovery fee per invoice; administrative fines reach EUR 2m for companies (EUR 4m repeat). Page updated 7 August 2026.

   Why it makes work harder: Long legal terms plus weak enforcement by SMBs mean cash is tied up for up to two months; SMBs must state penalties and the EUR 40 fee on every invoice and chase systematically.

8. Late Payment & Credit

   Late payments deprive SMEs of EUR 13bn of cash

   Detail: The Observatoire des délais de paiement 2025 report (2024 data) estimates SMEs would have EUR 13bn more cash if late payment ended: EUR 4bn for micro-businesses and EUR 9bn for other SMEs. Only 48% of large firms respected the 60-day legal limit in 2024, versus 73% of SMEs and 84% of micro-businesses; DGCCRF fines reached EUR 59.1m in 2025.

   Why it makes work harder: Small suppliers to larger customers carry weeks of unpaid invoices, so dunning, reminders and payment links directly relieve cash strain.

9. Late Payment & Credit

   Average payment delay of around 13.5 days, large firms worst

   Detail: Banque de France's release of the 2024 Observatoire report (11 July 2025) put average payment delay at 13.6 days at end-2024, up a day and above the European average, with large companies (1,000+ staff) averaging about 18 days late. It says persistent delays hurt SME and micro-business cash flow and cites a EUR 15bn shortfall.

   Why it makes work harder: Late B2B payment is structural in France, so SMBs need automatic reminders, statutory late fees and cash forecasting.

10. Market Size

    4.3 million micro-enterprises dominate the business base

    Detail: INSEE counts 4,332,366 micro-enterprises, 158,566 SMEs (excl. micro), 6,608 ETIs and 294 large enterprises (4.5 million total, non-agricultural, non-financial market sectors, 2021 data). Micro-enterprises employ 2.6 million FTE (17% of employment).

    Why it makes work harder: A very large base of very small firms without finance staff must now adopt e-invoicing, making simple all-in-one tools critical.
