E-invoicing

Your conductor for the reform

Between platforms, formats, deadlines and tools, e-invoicing is a project in its own right. French first, European next, we coordinate every stakeholder and guide you — fully independently — to turn it into a genuine lever for transformation.

Understanding it

What is e-invoicing?

An electronic invoice is an invoice dematerialised end to end, whose data follows a structure set by the tax authorities — enabling automated processing. Note: a simple PDF sent by email is not an electronic invoice.

E-invoicing

Issuing and receiving electronic invoices between VAT-registered French companies (B2B) and with the public sector (B2G).

E-reporting

Transmitting transaction data not covered by e-invoicing to the tax authorities: sales to individuals (B2C) and transactions abroad.

An opportunity, not just a constraint

Beyond compliance, tomorrow's opportunities

The reform structures data and automates accounting production. Done well, it frees up time for what really matters: steering and advisory.

Structured data

No more heterogeneous flows (paper, emails, PDFs): one consistent entry point, with no re-keying errors.

Automated production

Accounting largely automated and, eventually, pre-filled VAT returns.

More time for advisory

Value shifts towards steering, analysis and supporting the business owner.

The timeline

A phased entry into force

Adoption is phased from 2026 to 2027, based on company size. Effective preparation takes 10 to 18 months: anticipating means acting rather than reacting.

How it works

The new invoice flow

No more "Y-scheme": every invoice now passes through a Certified Platform. The Public Invoicing Portal (PPF) becomes a directory and data hub for the tax authorities.

The 4 flows of the ecosystem

What actually flows

E-invoicing

Sending an invoice in structured format to a VAT-registered B2B customer, through a Certified Platform.

Lifecycle

Tracking and reporting an invoice's status at every stage, from issuance through to payment.

E-reporting

Sending transaction data not covered by e-invoicing to the tax authorities: B2C sales, exports, certain receipts.

Directory

Looking up the national business registry and routing codes, to route the invoice to the right recipient.

The formats

Three formats, one emerging standard

Factur-X

The hybrid format: a human-readable PDF containing structured data. Best suited to small and mid-sized businesses, set to become the norm.

UBL

A fully structured (XML) format, machine-readable. Mostly used for high volumes and automated systems.

CII

Another structured XML format compliant with the European standard EN 16931, used in automated exchanges.

Our role

A conductor, not a software vendor

Vendors, Certified Platforms, IT, accounting teams, business owners: a successful compliance project involves many stakeholders. Our role is to coordinate them and guarantee a well-controlled evolution.

We sell no platform: we help you choose the right one, integrate it with your information system and bring your teams on board — clear governance (steering committee, project team), defined roles (RACI matrix) and controlled milestones.

  • IndependenceNo commercial ties with any vendor: our recommendations are objective.
  • Big-picture viewFlows, tools, teams, deadlines: we hold every thread of the project.
  • Compliance guarantorAn accounting firm, guaranteeing end-to-end tax and documentary compliance.
Our method

A 5-phase project approach

A proven methodology, paced by clear milestones and concrete deliverables at every stage.

012 to 3 weeks

Scoping — baseline assessment

Scope, objectives, governance and risks. Full mapping of your flows (O2C, P2P, closing), identification of friction points, RACI matrix and risk register.

024 to 6 weeks

Design

Translating needs into specifications, designing the target architecture, choosing the Certified Platform (PDP) and integration schemes with your existing systems.

036 to 8 weeks

Build & integration

Configuring connectors (ERP ↔ PDP), data transformation (Factur-X, UBL, CII), unit and end-to-end testing, user acceptance and documentation.

043 to 4 weeks

Rollout

Go-live, team training (CFOs, accountants, sales admin, IT), hypercare support and monitoring of the first flows and rejections.

05ongoing

Steering & ongoing compliance

Dashboard (rejections, delays, statuses), regulatory watch, configuration adjustments and continuous improvement. “Compliance isn't a state, it's a discipline.”

Tailored support

Adapted to your organisation

Large company, mid-cap or SME: the challenges differ, our method adjusts to your reality.

Large companies

Structured ERPs and IT systems: an asset, but also the challenge of adapting flows, managing many tools, interoperability and large-scale change management.

Mid-caps

An exposed middle ground: heterogeneous systems, effort often underestimated. Well anticipated, the reform becomes a lever to make data reliable and gain competitiveness.

SMEs / small businesses

The biggest leap (still a lot of paper and PDFs), but the strongest opportunity: less re-keying, shorter payment delays, full traceability.

Frequently asked questions

Everything you need in a few answers

Electronic invoice or PDF invoice: what's the difference?

A “classic” PDF invoice sent by email is a dematerialised invoice, but not an electronic invoice. An electronic invoice follows a data structure set by the tax authorities (Factur-X, UBL or CII), enabling end-to-end automated processing while keeping its legal evidential value.

What's the difference between e-invoicing and e-reporting?

E-invoicing covers the issuing and receiving of invoices between French, VAT-registered companies (B2B). E-reporting is the transmission to the tax authorities of transaction data not covered by e-invoicing: sales to individuals (B2C) and transactions abroad. Both follow the same timeline.

Will there be leniency at launch?

Yes. On July 10, 2026, the minister confirmed the timeline while announcing a lenient “start-up doctrine” for companies acting in good faith: no automatic penalties for those who document their difficulties and correct them, at least until the end of 2026. Note: this is not a grace period — the obligation still applies, you need to be ready and documented.

How long does it take to prepare?

Effective preparation generally takes 10 to 18 months depending on the size and complexity of the organisation. That's why you need to start now: act rather than react. A project that's started needs to be a project that's steered.

Is my company affected?

Yes, as soon as it is VAT-registered and established in France. All companies must be able to receive electronic invoices from September 1, 2026. The obligation to issue applies in waves, based on company size, through September 2027.

What is a Certified Platform (PDP)?

Formerly called a Partner Dematerialisation Platform, the PDP is a private operator registered by the State. Every B2B invoice will have to go through a PDP. Choosing the right platform is a structural decision — that's where our independent support really matters.

What happens to the Public Invoicing Portal (PPF)?

The PPF no longer transmits invoices directly (the end of the “Y-scheme”). It now acts as the business directory and data hub, relaying data to the tax authorities.

How do I choose a Certified Platform?

The choice rests on four criteria: coverage of your actual use cases (deposit invoices, credit notes, self-billing, international transactions), interfacing with your information system and accounting software, the operator's soundness and effective registration, and finally the full cost (subscription, volume, integration). We draft the specifications and comparison grid — with no commercial agreement with any vendor.

What does compliance cost?

It combines the Certified Platform subscription (often a few dozen to a few hundred euros per month depending on volume), any interfacing development, and internal preparation time. For an SME, most of the cost is organisational, not software: reworking processes and customer/supplier records is what demands the most effort.

What happens if an invoice is rejected by the platform?

It is not considered issued: the payment term doesn't start, delaying collection accordingly. The most common causes are incomplete customer records (SIREN, billing address) or missing mandatory mentions. That's precisely why the quality of your customer data must be addressed before the deadline, not after the first rejection.

Do electronic invoices need to be archived differently?

Yes. The retention obligation remains six years for tax purposes (ten years for commercial purposes), but it now applies to the structured format, with authenticity, integrity and readability requirements. Evidential-value archiving and a documented reliable audit trail become topics in their own right — the most common blind spot in the projects we audit.

Are our small suppliers affected too?

Yes, as soon as they are VAT-registered and established in France. All of them must be able to receive electronic invoices by September 1, 2026, whatever their size. Plan your communication to suppliers ahead of time: a supplier who isn't ready means a blocked purchasing flow on your end.
