E-Invoicing: 30 Million Invoices, 3% Rejection Rate — What SMEs Must Fix Before September 2027
The New Development
On October 27, 2026, Emmanuel Spinat, director of the French State Financial Information Agency (AIFE), shared the first quantitative assessment of the reform with IT for Business. The public invoicing portal has crossed 30 million invoices and €100 billion in transaction volume. The AIFE estimates it has exceeded half of its target for the first wave—large enterprises and mid-caps (ETIs)—describing it as "probably one of the fastest rollouts" in Europe.
The same assessment acknowledges a point of friction: roughly 3% of exchanges across the 155 certified platforms are rejected for non-compliance, down from 12% at launch. Starting in early November, the agency will pinpoint specific sender-receiver platform pairs showing abnormally high rejection rates. It also suspended data flows for 48 hours on one platform, Factuali, following a cyber incident it learned about through the press.
Timeline Reminder
Since September 1, 2026, all VAT-registered businesses in France must be able to receive electronic invoices via a certified platform. The obligation to issue electronic invoices currently applies only to large enterprises and mid-caps. It will extend to SMEs, VSEs, and micro-enterprises on September 1, 2027, alongside e-reporting for international transactions and B2C sales. The Minister of Public Accounts has indicated that no penalties will be enforced before the end of 2026: the current phase is a transition support period, not indefinite tolerance.
Why That 3% Matters for an SME
An inter-platform rejection is not an abstract statistic. It means an invoice never reaches the customer, so payment is never triggered. The AIFE explains the root cause: platform qualification testing covered standard scenarios, whereas "real life" produces edge cases with mandatory fields that vary by billing context. The 2026 pilot phase, sparsely attended by businesses, failed to surface them all.
To protect cash flow, the tax authority (DGFiP) temporarily allows sending a duplicate invoice via legacy channels alongside the new system. Some large corporations therefore maintain dual billing pipelines. However, the duration of this grace period is not fixed, and the AIFE warns that further announcements will follow. Any SME building its 2027 workflows around paper or PDF duplicates is taking a real risk.
What Business Leaders Are Saying
The Ipsos BVA barometer for Kolecto, published on October 1 and reported by Europe 1 and AFP, confirms a smoother rollout than feared: 21% of companies experienced bugs in September compared to 64% who anticipated them; 34% dealt with unprepared clients or suppliers versus 59% expected. Manufacturing is the most exposed sector, with 56% of trading partners not yet ready.
Support for the reform, however, is slipping: 54% of executives view it as beneficial for their business, down from 59% in 2025 and 69% in 2024. More importantly, only 14% say they are ready for September 2027 and 34% have started preparations. Yet the DGE's France Num 2026 barometer, published on September 28, ranks e-invoicing as the number-one digital priority for VSEs and SMEs (39%, +11 points), far ahead of AI (18%). Chartered accountants have become executives' primary digital advisors (41%, +23 points).
Operational, Financial, and Cyber Implications
Operational
The reform enforces structured data: company identifiers, mandatory legal fields, and lifecycle statuses (submitted, rejected, refused, paid). An SME whose accounting software, ERP, or CRM contains incomplete customer master records will generate rejections. Cleaning master data is the very first workstream—before selecting any software tool.
Financial
The AIFE notes that payment collection statistics will only become meaningful starting in November, given standard 30-day payment terms. Companies that fail to monitor invoice statuses closely will discover payment bottlenecks too late. Cash flow management must integrate these new statuses.
Cyber
The Factuali incident proves that the billing chain is now a prime target. Certified platforms must hold ISO 27001 certification and SecNumCloud hosting, and all are being audited before year-end. On the enterprise side, platform credentials and API connections deserve the same level of security as online banking.
Recommendations for SME and Mid-Cap Leaders
- Map your actual billing workflows: who issues invoices, from which tool, and with what exceptions (deposits, credit notes, self-billing, exports). Those edge cases are what trigger rejections.
- Clean and standardize customer and supplier master data in your ERP or accounting system before summer 2027.
- Select your certified platform using verifiable criteria: published compliance rates, native integration with your stack, incident reporting procedures, and shareholding structure if sovereignty matters to you (88% of executives surveyed by Ipsos BVA care about it).
- Test under real-world conditions with your top three customers and suppliers in the first half of 2027 rather than waiting for the deadline.
- Embed invoice lifecycle statuses into cash-flow tracking and train accounting and sales teams on the new rejection codes.
- Do not build your 2027 workflow around paper/PDF duplicates, as the tolerance window has no guaranteed end date.
Caveats and Limitations
The AIFE figures cover the first wave (large enterprises and mid-caps); they do not predict how millions of smaller businesses will fare in 2027. The Ipsos BVA survey was commissioned by a certified platform owned by Crédit Agricole: its findings are self-reported and should be read in that context. Finally, the exact duration of the transition period and the post-2026 penalty regime still await clarification from the DGFiP—this point will be updated as soon as official guidance is published.
Conclusion
The infrastructure works, transaction volumes are flowing, and rejection rates are falling. But the 2027 switchover will involve far more companies, with less tooling and, by their own admission, limited preparation so far. The remaining ten months are sufficient—provided leaders tackle data quality and business processes first, and software second.

Frequently Asked Questions
Does my SME already have to issue electronic invoices?
No. Since September 1, 2026, you must be able to receive them via a certified platform. The mandate to issue electronic invoices and submit e-reporting applies to SMEs, VSEs, and micro-enterprises starting September 1, 2027.
What happens if an invoice is rejected between two platforms?
It is not delivered to the customer and must be corrected and reissued. The AIFE observes roughly a 3% rejection rate, most often caused by missing mandatory fields or special billing scenarios.
Are there penalties for non-compliance or delays?
The Minister of Public Accounts announced that no penalties will be applied through the end of 2026. The subsequent enforcement regime will be specified by the DGFiP; it is prudent not to rely on extended leniency.
