The electronic invoicing reform comes into effect on September 1, 2026, for receipt, and then on September 1, 2027, for mandatory issuance by all VAT-registered businesses. Optimizing the management of your invoices in the digital age is not just about choosing software: it involves rethinking the entire process, from data format to transit platform, including automated accounting reconciliation.
Structured formats and EN 16931 standard: the technical foundation of electronic invoicing
A PDF sent by email will no longer be considered an electronic invoice in the regulatory sense. The reform mandates the use of standardized UBL, CII, or Factur-X formats, all compliant with the European standard EN 16931. This technical constraint radically changes the game for accounting automation.
With a structured format, each piece of data (net amount, VAT, SIRET, due date) is tagged and machine-readable. The accounting software ingests the invoice without manual entry, eliminating transcription errors and speeding up reconciliation with purchase orders.
We recommend testing the compliance of your outgoing flows right now. Approved dematerialization platforms (PDP) and the public invoicing portal (PPF) reject poorly formatted documents. A rejected invoice means a blocked payment and a potential supplier dispute. Teams that are already working on their document processes via rpeeck.com save time on this technical compliance.
Platform choice: PPF, PDP, or dematerialization operator
The choice of platform determines the level of automation available. Three options coexist within the French system, and their capabilities differ significantly.
- The public invoicing portal (PPF) ensures the transit and transmission of data to the tax administration. It covers the minimum regulatory requirements, without advanced management features.
- Partner dematerialization platforms (PDP), approved by the administration, offer complementary services: automatic reconciliation, legally valid archiving, management of the invoice lifecycle up to payment.
- Dematerialization operators (OD) act as technical intermediaries but must go through the PPF or a PDP for legal transmission.
For a company processing a significant volume of supplier invoices, using a PDP allows for direct integration of incoming flows into accounting. The gain is measured in the processing and approval of invoices, not just compliance.
Automatic reconciliation and supplier invoice approval process
The processing of supplier invoices remains the area where efficiency gains are most tangible. A traditional paper circuit involves receipt, digitization, entry, hierarchical validation, and then payment. Each step introduces a delay and a risk of error.
The three-way reconciliation (purchase order, receipt, invoice) becomes automatable as soon as the invoice arrives in a structured format. The software compares the tagged data without human intervention. Only discrepancies trigger an alert and manual validation.
The approval process also deserves a redesign. We observe that many companies replicate their paper workflow in a digital tool, with the same bottlenecks. Defining thresholds for automatic validation (below a certain amount, direct approval by the purchasing department) significantly reduces the average processing time.
Supplier data: quality upstream conditions the entire process
A poorly maintained supplier database sabotages automation. An incorrect SIRET, an outdated billing address, or an invalid VAT identifier causes rejection by the transit platform. Before deployment, a systematic cleaning of the third-party database is essential: verification of legal identifiers, updating bank details, removal of duplicates.
Tax compliance and e-reporting: often underestimated obligations
The reform is not limited to the exchange of invoices between businesses. The system includes an e-reporting component for transactions outside the scope of e-invoicing: sales to individuals (B2C), operations with foreign partners, certain exempt transactions. These flows must be reported to the administration via the PPF or a PDP according to a schedule aligned with that of electronic invoicing.
Many companies focus on domestic B2B and discover this additional obligation too late. The exact scope concerns domestic B2B exchanges subject to VAT for e-invoicing, while e-reporting covers the rest. Anticipating this dual flow avoids urgent compliance measures.
Legally valid archiving and retention period
Electronic archiving must guarantee the integrity and authenticity of the document for the entire legal retention period. Simple storage on a server is not enough. PDPs generally offer compliant archiving, but check the contractual conditions: covered duration, restitution format, data reversibility in case of a change of provider.
Level of business preparedness: a persistent gap
Bercy publicly acknowledges that not all companies will be ready by September 1, 2026, and anticipates a gradual ramp-up. Smaller entities, often lacking a dedicated accounting department, accumulate the most delays.
The main risk is not immediate administrative sanction, but the inability to receive and properly process electronic invoices issued by already compliant suppliers. An unprepared company faces payment delays and loses commercial credibility.
The priority for organizations that have not yet started: choose a platform (PPF or PDP), check the compatibility of their accounting software with UBL, CII, or Factur-X formats, and clean their third-party database. These three actions cover the essential critical path before the regulatory deadline.
