E-Invoicing in France 2026 | Electronic Invoicing Compliance

E-Invoicing in France 2026 — Hayot Expertise Paris#

France's mandatory e-invoicing reform is the most structurally significant tax change of the decade for French businesses. Hayot Expertise, located at 58 rue de Monceau (75008 Paris) and a certified Pennylane partner, supports SMEs and small businesses through every stage of this transition: platform selection, process audit, software deployment and team training. Act now — September 2026 is closer than it seems.

The reform, originating from the 2020 Finance Act and the ordinance of 15 September 2021, aims to modernise the B2B invoicing chain in France. The tax authority (DGFiP) gains near-real-time visibility over VAT flows, enabling it to combat fraud and pre-fill VAT returns in the future.

For businesses, the benefits are tangible:

• Faster payment cycles: structured electronic invoices are processed 3 to 5 times faster than paper invoices
• Zero lost documents: all invoices are automatically archived in your platform
• Automatic reconciliation: bookkeeping is updated in real time, with no manual entry
• Built-in compliance: the platform validates all mandatory fields before transmission

The DGFiP estimates the reform could save French businesses €4.9 billion per year through reduced invoicing processing costs.

The reform applies in two phases depending on company size:

1 September 2026:

• Mandatory receipt of electronic invoices for all VAT-registered businesses in France
• Mandatory issuance for large companies (GE) and mid-sized companies (ETI) only

1 September 2027:

• Mandatory issuance for SMEs and micro-businesses

Key takeaway: even if you are a small business, you must be able to receive electronic invoices from September 2026. You need to be ready for structured formats (Factur-X, UBL, CII) well before your own issuance deadline.

The reform covers all VAT-registered businesses in France for their domestic B2B transactions (between French companies):

• In scope: all companies (SAS, SARL, SA), professional practices incorporated as companies, VAT-registered tradespeople and retailers
• Out of scope for e-invoicing (but subject to e-reporting): sole traders below the VAT exemption threshold, B2C transactions, cross-border transactions
• E-reporting is mandatory for all transactions not covered by e-invoicing (sales to private individuals, exports)

Compliance audit of your current processes#

Our mission begins with a thorough review:

• Mapping of incoming and outgoing invoice flows (volume, formats, transmission channels)
• Analysis of your current tools (Word, Excel, invoicing software, ERP) and identification of gaps vs. regulatory requirements
• Verification of mandatory fields on your current invoice templates
• Audit report with prioritised action plan and compliance calendar

Timeline: 1 audit day + report within 48 hours

Platform selection (PDP or PPF)#

The choice between the free Public Invoicing Portal (PPF / Chorus Pro) and a private approved partner platform (PDP) is critical. We evaluate together:

• Your monthly invoice volume (issuance and receipt)
• Your integration needs with your accounting and ERP systems
• Your budget and digital maturity
• Advanced features you need (automatic matching, status tracking, legal archiving)

For most SME clients, we recommend Pennylane as PDP: native accounting integration, intuitive interface, French support. As a certified Pennylane partner, we deploy it end-to-end.

Software deployment and configuration#

• API connection between your invoicing platform and accounting tools
• Configuration of invoice templates in structured formats (Factur-X first for the transition)
• Historical data migration (product catalogue, clients, suppliers)
• Internal approval workflow configuration (supplier invoice validation before payment)
• Interoperability tests with your main clients and suppliers

Team training#

• Training on new invoicing processes (issuance, reception, rejection handling)
• Internal procedure documentation
• 3-month post-go-live support
• Dedicated helpline for post-deployment questions

E-invoicing (B2B electronic invoicing)#

Issuance and receipt of invoices in a structured format (machine-readable data), transmitted via an approved platform. Three recognised formats:

• Factur-X: hybrid PDF + embedded XML data — ideal for the transition as it is readable by both humans and machines
• UBL 2.1: pure XML format, European standard used in EDI exchanges
• UN/CEFACT CII: XML format used in industry and wholesale trade

E-reporting (transactional data transmission)#

For transactions not covered by e-invoicing (B2C, cross-border sales, VAT-exempt transactions), companies must periodically transmit summarised data to the tax authority via their platform.

In addition to the usual legal mentions, electronic invoices must include:

• The SIREN of the client (mandatory — without it the invoice is rejected)
• The nature of the transaction (goods delivery / service provision / mixed)
• The delivery address (if different from the billing address)
• The client's intra-community VAT number (if applicable)
• The invoicing currency

Failing to adopt e-invoicing exposes your company to:

• €15 per invoice not issued in the required format, capped at €15,000 per year
• €250 per missing transmission for e-reporting, capped at €15,000 per year
• In cases of deliberate non-compliance, a 40% surcharge on reassessed VAT

Beyond financial penalties, non-compliant companies risk invoice rejections from large clients who will be subject to mandatory issuance from September 2026.

1. Thinking a PDF sent by email counts as an e-invoice: it does not. A PDF is treated as a dematerialised paper invoice, not a structured electronic invoice.
2. Waiting until the last minute: migrating to a PDP takes 2 to 4 months. If you wait until June 2026, it will be too late.
3. Choosing the cheapest PDP without evaluating integration: a poorly integrated PDP negates all productivity gains.
4. Forgetting e-reporting: even if your activity is mainly B2C, you will still need to transmit transactional data to the tax authority.
5. Skipping interoperability tests: compatibility between PDPs must be validated before go-live, especially with large clients.

A 100% digital firm since its founding and a certified Pennylane partner, Hayot Expertise already manages thousands of e-invoicing flows for its clients. We have supported over 50 Parisian businesses through digital invoicing migrations since 2022. Our expertise combines regulatory knowledge of the reform with hands-on mastery of the tools.
