E-Invoicing in France 2026 | Electronic Invoicing Compliance

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: a structured invoice enters your client's approval workflow directly, with no re-keying and no chasing a mislaid document
• Zero lost documents: every invoice is centralised in your platform (evidential-value archiving is a separate subscription)
• 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 report on VAT in the digital age puts the net gain at €4.50 per outgoing invoice, net of compliance costs.

The reform applies in two phases depending on company size. The first one is already in force:

1 September 2026 (in force):

• 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: if you are a small business, the obligation to receive electronic invoices already applies to you, since 1 September 2026. You need to handle structured formats (Factur-X, UBL, CII) now, without waiting for your own issuance deadline in 2027.

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): B2C transactions and cross-border transactions. No category of business is exempt: firms under the VAT franchise regime, micro-entrepreneurs included, are in scope and have had to be able to receive electronic invoices since 1 September 2026
• 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

Choosing your approved platform (PA, formerly PDP)#

There is no free State option: since the October 2024 refocus, the public invoicing portal no longer issues or receives business-to-business invoices, it runs the recipient directory and concentrates the data sent to the tax authority, and Chorus Pro remains reserved for invoices addressed to public bodies. The choice is therefore between approved platforms, on integration, formats and price. 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, registered as an approved platform by the DGFiP since 11 December 2025 (official impots.gouv.fr list): 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
• A single point of contact, your chartered accountant, for questions after go-live

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. Sales to private individuals and international operations are in scope; for services, payment (cash-collection) data is transmitted too. The transmission frequency depends on your VAT regime. E-reporting penalties (€500 per missing transmission, capped at €15,000 per calendar year, Tax Code article 1788 D) are separate from the e-invoicing ones.

The public portal no longer issues or receives B2B invoices: it runs the recipient directory and concentrates the data sent to the tax authority, while Chorus Pro stays reserved for invoices to public bodies. An approved platform is an operator registered by the DGFiP for three renewable years, after review of its file and successful interoperability testing. The official list published by the tax authority came out on 16 January 2026 with a first 101 platforms, and it grows as applications are approved: always check there the status of any solution offered to you.

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:

• €50 per invoice not issued in the required format, capped at €15,000 per calendar year (Tax Code article 1737, III; raised from €15 to €50 by the 2026 Finance Act)
• €500 per missing transmission for e-reporting, capped at €15,000 per calendar year (Tax Code article 1788 D; raised from €250 to €500 by the 2026 Finance Act)
• In cases of deliberate non-compliance, a 40% surcharge on reassessed VAT

Neither fine applies to a first breach committed during the current calendar year and the three preceding years, provided it is corrected spontaneously or within thirty days of a first request from the tax authority (Tax Code, articles 1737, V and 1788 D).

Beyond financial penalties, non-compliant companies risk invoice rejections from large clients and mid-sized companies, which have been subject to mandatory issuance since 1 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: allow several months between the audit and go-live, because configuration, interoperability testing and training cannot be compressed. Starting the project in spring 2026 leaves no margin.
3. Choosing the cheapest platform without evaluating integration: a poorly integrated platform 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 approved platforms must be validated before go-live, especially with large clients.

Compliance is the deadline, not the destination. The businesses that prepare early use the reform to digitalise their whole order-to-cash and purchase-to-pay cycle rather than just tick a regulatory box. Three concrete gains stand out:

• Shorter payment delays. Because a structured invoice is matched and routed automatically, it reaches the right approver in hours instead of days. Clients can no longer claim "we never received it", so they pay faster, which mechanically reduces your days-sales-outstanding (DSO) and frees up cash.
• Real-time visibility. Once invoices flow through an approved platform connected to your accounting, your revenue, receivables and payables update continuously. You stop discovering your cash position three weeks after month-end and can steer the business on current data.
• Fewer manual errors and less VAT risk. Mandatory fields (client SIREN, transaction type, VAT number) are validated by the platform before transmission, and the four lifecycle statuses (deposited, rejected, refused, cashed) give you an auditable trail. As the DGFiP moves towards pre-filled VAT returns, clean structured data is also your best protection in a tax review.

We design the migration around these gains, not only around the September 2026 and 2027 deadlines, so the project pays for itself in time saved rather than sitting on your cost line.

Whatever your size, you should be able to answer five questions:

1. Can you receive a structured invoice today? Since 1 September 2026 every VAT-registered business must be able to, regardless of its own issuance deadline.
2. Have you chosen your platform? Allow several months between the audit and go-live: with the reception obligation already in force, a business that has not switched yet is behind, not ahead.
3. Are your client and supplier master data clean? Missing SIREN numbers or VAT IDs are the first cause of rejected invoices.
4. Is your accounting tool connected? The productivity gains only materialise once the platform feeds your books automatically.
5. Are your teams trained? Issuance, reception and rejection handling become new day-to-day reflexes for accounting and sales staff.

If any answer is "no", we can run the audit and build your compliance calendar in a single week.
