Mandatory Electronic Invoicing in France: What It Changes for Debt Collection

On September 1st, 2026, every business liable to VAT in France will be required to receive its B2B invoices through a private Approved Platform, in a structured electronic format. Large enterprises and mid-sized companies (ETIs) must issue e-invoices from that same date. SMEs, very small businesses and micro-entrepreneurs follow one year later, on September 1st, 2027.

The timeline was confirmed by Article 91 of the 2024 Finance Act and politically locked after the rejection, on April 11th, 2025, of an amendment proposing a further postponement. What is presented publicly as a tax compliance project is in fact a deep overhaul of cash collection: new mandatory fields, digital lifecycle statuses, automated rejection of non-compliant invoices, and penalties that the 2026 Finance Act has tripled.

For a CFO or a managing director, the question is no longer “does this concern me?”. It is “what does it change for my payments?”. This guide unpacks the timeline, the obligations, and above all what the reform actually does, or fails to do, for your payment delays.

The official timeline: 2026, then 2027

Deployment is asymmetric, based on company size as defined by the French LME law (company-size thresholds from Act 2008-776 and Decree 2008-1354).

On September 1st, 2026, three obligations enter into force simultaneously:

• Mandatory reception for every VAT-registered business established in France, including those under the VAT exemption regime and micro-entrepreneurs.
• Mandatory issuance for large enterprises (over 5,000 employees or more than 1.5 billion euros in revenue) and mid-sized companies (ETIs).
• Mandatory e-reporting for the same entities, covering domestic B2C transactions, international B2B flows and the settlement of service transactions.

On September 1st, 2027, issuance becomes mandatory for every business: SMEs, very small businesses, micro-entrepreneurs. E-reporting is generalised on the same date.

A three-month regulatory buffer allows the government to shift the deadlines by decree, to December 1st, 2026 or 2027, but this is no longer a political safety net. It is reserved for late-stage technical incidents. The parliamentary vote of April 11th, 2025 and the formal position of the National Order of Chartered Accountants closed the door to any broader delay.

The trap for SMEs that supply large customers

While issuance only becomes mandatory in September 2027 for SMEs, the ability to receive electronic invoices must be operational by September 2026. Any SME invoicing a large corporate customer will therefore need to connect to an Approved Platform from 2026, even if it keeps issuing plain PDFs until the following year. In practice, most SME suppliers of large accounts will switch to electronic issuance in 2026, pre-emptively.

The end of the free PPF changes the economics

The original architecture included a free Public Invoicing Portal (PPF), managed by the AIFE, that would have let VSBs and SMEs enter, issue and receive invoices at no cost. On October 15th, 2024, a Ministry of Economy press release formally abandoned that role. The official reasons: sufficient maturity of the private market, budget constraints, and lessons drawn from failed international rollouts (Poland’s KSeF in particular).

The PPF now keeps only two missions:

1. The central recipient directory, the unique reference listing the roughly 11 million VAT-registered entities in France. Each SIREN number declares which Approved Platform will receive its invoices.
2. The tax data concentrator, the sole entry point for the DGFiP, receiving invoice data extractions and e-reporting transmissions from every Approved Platform.

Every business, without exception, must therefore subscribe to a private Approved Platform (the new official name; the term Partner Dematerialisation Platform, or PDP, was used until mid-2025). By April 13th, 2026, roughly 115 platforms had been fully approved, with a further 20 awaiting interoperability tests.

Some platforms offer partial free tiers for their existing clients: Qonto for its banking customers, Indy, Dougs and Tiime for sole traders, or jefacture.com for clients of affiliated chartered accountancy firms. But no free offer currently covers the full scope of issuance, reception and e-reporting for every use case.

Four new mandatory fields on your invoices

Decree 2022-1299 of October 7th, 2022 extends the list of legal fields set by article 242 nonies A of the French Tax Code. From September 1st, 2026, every B2B invoice must carry the following four additional fields, or risk automatic technical rejection by the recipient’s Approved Platform:

• The client’s SIREN number (9 digits, not the 14-digit SIRET). This number drives invoice routing through the central directory. A customer database with missing or incorrect SIRENs will become an immediate bottleneck.
• The delivery address, when it differs from the billing address.
• The category of the transaction: goods, services or mixed. This field conditions the applicable VAT regime and the VAT chargeability calculation.
• An explicit mention of the option for VAT on debits, where the supplier has opted for that regime rather than VAT on collections.

These fields add to the existing French mandatory invoice elements (party identities, invoice number, date, line items, quantities, unit prices, VAT rates, payment terms, late payment penalties, the mandatory 40 € late payment recovery indemnity, etc.). The existing legal framework for unpaid invoices remains fully applicable.

Three structured formats: Factur-X, UBL 2.1, UN/CEFACT CII

Three structured formats are authorised, all compliant with the European standard EN 16931. The issuer chooses, and the recipient’s Approved Platform handles format conversion if needed.

• Factur-X: a Franco-German hybrid format (identical to ZUGFeRD 2.x), combining a human-readable PDF/A-3 and an embedded structured XML file. Version 1.08 published on December 4th, 2025. It is the preferred format for SMEs and chartered accountants, because it preserves human readability during the cultural transition.
• UBL 2.1 (Universal Business Language): pure XML, OASIS standard. Favoured by large enterprises and high-volume EDI flows.
• UN/CEFACT CII (Cross Industry Invoice): pure XML, United Nations standard, with up to 2,000 optional fields. Used in international trade and certain industrial verticals.

Standards maintenance has been transferred to AFNOR since January 2025, via the E-Invoicing Commission (XP Z12-012, XP Z12-013 and XP Z12-014 standards). The DGFiP has acted as Peppol Authority for France since July 8th, 2025, guaranteeing interoperability with European flows.

Key point: from September 1st, 2026, a plain PDF sent by email is no longer a valid invoice for domestic B2B transactions. An attached PDF may still be sent for information or comfort, but it carries no fiscal or legal value on its own.

Lifecycle statuses: the real game-changer for cash

This is the most under-appreciated and most transformative aspect of the reform for collections. The Approved Platform must transmit, to the tax authority, the issuer and the recipient, a set of normalised statuses that track each invoice through its lifecycle.

Mandatory statuses

Four statuses are imposed by the DGFiP:

• Submitted: the invoice has been issued by the supplier and passed to its Approved Platform. This is the official starting point.
• Rejected: the recipient’s Approved Platform rejects the invoice on technical grounds (non-compliant format, invalid SIREN, missing mandatory field).
• Refused: the buyer refuses the invoice on commercial grounds, selecting one of the 40 DGFiP motive codes (quantity dispute, price dispute, quality issue, etc.).
• Settled / Payment Transmitted: for service transactions taxed on collection, this status triggers VAT chargeability.

Recommended statuses, critical for credit management

AFNOR defines several non-mandatory but highly recommended statuses: Made Available, Taken in Charge, Approved, Partially Approved, Payment Transmitted. These have no fiscal value but enormous operational value: for the first time, a supplier can know, without picking up the phone, whether its invoice has been opened, read, validated or scheduled for payment.

In cash forecasting, an “Approved” status turns a probabilistic cash-in estimate into a near-certain datapoint. In collections, a “Refused” status with its codified motive eliminates vague disputes and accelerates resolution.

A word of warning flagged by the French Credit Managers Association (AFDCC): an “in dispute” or “suspended” status does not automatically suspend the payment deadline. It has no legal effect on debt enforceability. Collection must therefore continue to run under the contractual terms, even if the invoice carries a “disputed” status. Without procedural vigilance, this misunderstanding becomes a lever for abuse.

Penalties tripled by the 2026 Finance Act

The 2026 Finance Act, enacted on February 19th, 2026, significantly toughened the penalty regime. Many articles still circulating online quote the obsolete 2024 amounts: your compliance grid needs to be updated.

A right to err is maintained: no penalty for the first breach of the current civil year or the three prior years, provided the business self-corrects or regularises within 30 days of an administrative request. The DGFiP has announced it will prioritise support during the first months. That tolerance has limits.

Audits rely on a new lever: the automated cross-check of issued and received invoices via the mandatory client SIREN. Where the DGFiP used to audit post-hoc on samples, it will have a near-real-time view of the domestic B2B flow from 2026 onward.

What the reform changes for your cash collection

Payment delays are the most poorly communicated aspect of the reform. Official messaging alternates between “e-invoicing will streamline payments” and “this is a fiscal project, payment delays are out of scope”. The reality sits in between.

What improves mechanically

Invoice routing is guaranteed. No more lost emails, no more “I never received your invoice”, no more unreadable scans. The invoice is submitted, tracked and timestamped. For the supplier, a classic excuse for late payment disappears.

Internal processing time at the customer’s end drops. A Factur-X invoice contains structured XML that feeds directly into accounts payable workflows. Matching checks (purchase order, delivery note, invoice) automate. The unavoidable lag between reception and payment shortens by several days.

Refusal traceability becomes objective. A commercial refusal must carry a DGFiP motive code. Vague disputes, untreatable without a phone call, become codified signals a collection tool can act on.

What does not change, or not enough

Large corporates’ cash policies do not change by decree. The Banque de France’s 2024 Observatory of Payment Delays documents a 13.6-day average delay in Q4 2024, up one day year over year, with large enterprises above 1,000 employees leading the pack at 18 days. The Altares study of September 2025 confirms the 2025 deterioration.

The shortfall for SMEs and micro-businesses is quantified by the Banque de France at 15 billion euros of missing cash in 2024. The KPMG 2024 study of working capital puts the average DSO at 64 days, of which 19 days of hidden delay beyond contractual terms.

The Italian experience is revealing. The SDI, deployed in 2019, recovered an estimated 6 billion euros per year in legitimate tax revenue. Yet on payment delays, Italy still posts a 17-day average delay in 2025, one of the highest in Europe. The United Kingdom, without central clearance, performs better. The conclusion is unambiguous: technology alone does not pay invoices.

The reform’s blind spot: collection is still required

This is also the diagnosis from Paris Île-de-France Chamber of Commerce in its September 2025 note: without a broader payment culture shift, the rigidity of technical rejections can be used by bad payers as a pretext to delay settlement further. The risk is documented.

The reform hands you three levers you will have to exploit:

1. Early signals: “Approved” or “Made Available” is a trigger for preventive follow-up, before the due date.
2. Unambiguous traceability: it becomes impossible for a client to claim they never received the invoice.
3. Codified refusals: each “Refused” carries an operationally exploitable motive.

You still need a tool capable of consuming these signals in real time, cross-referencing them with each client’s payment history, and triggering the right follow-up without human intervention. That is precisely the role of a modern debt collection software.

Your six-month preparation roadmap

Software vendors and chartered accountants converge on a minimum six-month roadmap.

Six months out (for September 2026, you should be at this stage by March 2026 at the latest): audit your invoice flows, map inbound and outbound volumes, and clean your master data (SIREN, SIRET, intra-EU VAT numbers). This is the most under-estimated cost item and often the heaviest in internal resource.

Three months out: select and configure your Approved Platform. Register in the central directory. Run conformance tests on live flows with a sample of customers and suppliers. Train your finance, sales admin and procurement teams.

One month out: run a pilot on a limited scope, ramp up progressively, monitor technical rejections. Adjust invoice templates and master records.

Typical budget for a French SME lands between 0 and 5,000 €, depending on the level of integration. Approved Platform subscriptions range from a few euros per month (for free banking tiers) to several hundred euros for enterprise-grade offerings. The hidden cost lies in data hygiene and internal process change.

Minimum checklist before September 2026

1. Identify the company size category under LME (micro, SME, ETI, large enterprise), as of January 1st, 2025 on the last closed fiscal year.
2. Select an Approved Platform fit for your volumes, existing accounting integrations and vertical. Check the up-to-date official list on impots.gouv.fr.
3. Register in the central directory at facturation.chorus-pro.gouv.fr/annuaire, declare your receiving platform and your billing electronic addresses.
4. Clean your customer master data: complete SIRENs, up-to-date SIRETs, valid intra-EU VAT numbers. Enforce a control at every new account creation.
5. Update your invoice templates to include the four new mandatory fields.
6. Set up the supplier master data symmetrically, since reception is already in scope from 2026.
7. Verify that your accounting software or ERP is compatible with the chosen Platform. Confirm native API or connector availability.
8. Organise evidentiary-grade archiving over 6 to 10 years depending on the case.
9. Train your teams: accounting, sales admin, procurement, collections.
10. Plug your debt collection software into the lifecycle status feed to exploit early signals from day one.

Conclusion: an e-invoice does not collect, it triggers

The reform is a fiscal sovereignty project, not a small-business cash stimulus plan. It will secure several billion euros of VAT annually, streamline B2B invoice routing and remove a generation of documentary friction. But it will not turn, on its own, a structurally slow payer into a prompt one.

The real win lies in the articulation between the Approved Platform, which handles compliance, and the debt collection software, which turns signal into cash. An invoice still at “Submitted” status 48 hours in, for a client normally diligent, is an alert. An “Approved” status 20 days before the due date is a strong signal. A “Refused” status with a codified motive is a resolvable ticket from day one.

The companies that will extract the most value from the reform are those treating September 2026 not as a compliance checkbox, but as an upgrade of their entire cash collection chain, from invoice to settlement.
