Thirty-one incidents were recorded across the status pages of 12 approved e-invoicing platforms (plateformes agréées, or PA) between 1 and 26 September 2026, according to a review published by comparateur-facturation-electronique.fr on 26 September 2026. Of those incidents, 9 directly disrupted operational flows — invoice issuance, receipt, processing status updates, the business directory, or e-reporting — while 22 affected the platform application or ancillary services. The platforms affected: Weproc, Sage, Spendesk, Invopop, Cecurity, Ecosio, SUPER PDP, MyUnisoft, Dokapi, Tungsten Automation France, Pennylane and EEZI.
Context: Certification does not guarantee availability
France’s mandatory e-invoicing reform (Réforme de la Facturation Electronique, RFE) entered into force on 1 September 2026, initially requiring all large and mid-market companies (grandes entreprises and ETI) subject to French VAT to be capable of receiving structured invoices via a certified platform (PA) approved by the French tax authority (DGFiP). Certification confirms that a platform meets the regulatory technical specifications. It does not guarantee operational availability — and the first month of deployment made that distinction concrete for many businesses.
The risk that caught companies off guard was not regulatory: their platform was certified, their flows configured, their teams trained. The risk was infrastructural — their approved platform experienced technical difficulties at the precise moment flows needed to transit.
Impact on businesses
The most severe incident of the month involved Sage. Between 2 and 10 September 2026, invoices submitted through its approved platform were not delivered to recipients for approximately 8.5 days (comparateur-facturation-electronique.fr, 26 September 2026). For a mid-market business issuing several hundred invoices per week, 8.5 days without delivery means an interrupted payment chain, supplier escalations, and a materially delayed cash collection cycle. Sage suffered three additional incidents that month: onboarding of new companies was blocked for approximately two days (5–7 September), a slowdown caused by load on France’s public government portal lasted around four days (11–15 September), and a degradation affecting receipt, status updates and e-reporting lasted 3h53 on 10 September.
Other platforms were affected over shorter but notable windows. SUPER PDP experienced a directory outage on 18 September, during which incorrect data was transmitted to the tax authority — a qualitatively different type of incident: it was not invoices failing to arrive, but the business identification registry broadcasting inaccurate data. Ecosio reported disruption to France invoice processing on 21 September (2h28). Weproc saw degraded Peppol sending from the first day of operations (1h40 on 1 September). Spendesk accumulated three separate incidents during the month. Contributing external factors included outages at Microsoft and Salesforce, load spikes on France’s public government portal, and a Peppol registry migration.
For IT directors and CFOs, these incidents raise a practical question: what happens inside your ERP when your approved platform is unavailable? The answer varies by ERP vendor. Some buffer flows and automatically retry once the platform recovers. Others leave documents in error state without proactive alerting. Fallback capability — or its absence — is rarely documented in initial vendor selection scorecards.
What to monitor going forward
The DGFiP has not yet issued a position on platform liability when an incident causes a delay in e-reporting transmission. If your approved platform goes down on a filing deadline, does a good-faith tolerance apply? The legal question remains open.
Also worth tracking: month-on-month aggregated availability statistics. September’s reliability baseline will serve as the reference point for first contract reviews at year-end. Monitoring the status pages of approved platforms — long treated as optional housekeeping — is now a component of operational risk management for any company operating under the French e-invoicing mandate.
