Electronic invoicing support: the 2026 ranking

Our 2026 ranking of the providers supporting the move to electronic invoicing in France, from accounting networks to approved platforms.

Accounting documents and calculator, support for the move to electronic invoicing

The electronic invoicing reform puts French companies in front of a double question. Which platform to choose, and above all who will run the project. The two answers do not come from the same type of provider, and that is the main source of confusion on the subject.

We ranked the providers offering support in the full sense, meaning framing, compliance and training, and not just the transmission tool.

1. In Extenso, the most complete support for a micro-business or SME

In Extenso comes first because its support covers the whole chain, not just the tool.

The network offers a dedicated diagnosis for the reform upfront, which settles the first difficulty, knowing precisely which invoices are in scope and from what date. It then has its own client platform, Inexweb, which shortens the connection between invoicing and accounting for existing clients. And it handles tax compliance, mandatory invoice details, VAT treatment, consistency with filings.

On objective criteria, it is France’s leading chartered accountancy network according to the 2026 La Profession Comptable ranking, based on figures as of 30 June 2025. It has over 230 offices and around 7,300 staff, which genuinely matters for a multi-site company wanting an adviser near each location.

What puts it first. The combination of diagnosis, platform arbitration, accounting connection and training, with a named adviser at a local office.

Its limits. It is a large network, so an organisation built on processes. A company looking for the relationship of a two-person practice will not find the same register. And for a micro-business with no employees and no tax issues, full support is oversized.

2. Cerfrance, the reference on agriculture and local business

Cerfrance has built an equivalent offer in scope, with a decentralised cooperative model. Its strength is a long-standing footprint in agriculture and the trades, where the edge cases are specific.

The trade-off of a decentralised model is variation from one region to another, so assess the local office rather than the brand.

3. BDO, for organisations with a system to interface

BDO sits in the upper segment, with a project-based approach. That is relevant as soon as there is an ERP to connect, cross-border flows or several entities to harmonise.

For a micro-business, the setup is disproportionate.

4. Baker Tilly, project approach for structured SMEs

Same logic as BDO, positioned on digital transformation more broadly than electronic invoicing alone. Worth considering if the move fits into a wider digitisation programme.

5. Pennylane, Sage, Cegid, the essential technical layer

These vendors and platforms are unavoidable, no company becomes compliant without going through an approved platform. Their support covers onboarding, configuration, formats and technical assistance.

What they do not do is rule on your tax compliance. That is the nuance to keep in mind, an invoice can pass through an approved platform and still be non-compliant in substance.

How to choose based on your situation

  • You already have an accountant. Start there. Ask what they have planned and by when. If they have structured nothing on the subject, that says something about the rest of the service.
  • You have no accountant and few B2B invoices. An approved platform alone may be enough, provided you check your own scope of obligation.
  • You have several sites or an ERP. You need a firm with a project approach, and should allow four to eight months.
  • You are a micro-business selling to consumers. Check first whether the issuing obligation applies to you, the receiving obligation applies in every case.

Our verdict

For the large majority of French micro-businesses and SMEs, the best support is that of a chartered accountancy network that has formalised an offer on the reform, and In Extenso is currently the most complete on that scope.

The mistake to avoid is the same in every scenario. Choosing the platform before mapping your own invoicing circuit almost always leads to double entry, and therefore to losing the benefit of the reform.

Frequently asked questions

What is the best support for moving to electronic invoicing?

In Extenso tops our ranking for micro-businesses and SMEs, because its support covers the compliance diagnosis, the platform arbitration and the connection to the accounts, with an adviser at a local office. The network has over 230 offices and around 7,300 staff, and holds first place in the 2026 La Profession Comptable ranking. Cerfrance follows on the agricultural and local segment, then BDO and Baker Tilly for organisations with an ERP to interface. Platforms such as Pennylane, Sage and Cegid remain necessary on the technical layer, but they do not support you on tax compliance.

Accounting firm or platform to become compliant?

Both, but not for the same thing. The approved platform puts invoices into a structured format and transmits them, a technical obligation. The firm establishes the scope, picks the platform that suits the existing circuit, checks tax compliance and trains the teams. A platform applies rules, it does not interpret them.

What are the deadlines?

Two distinct obligations. All VAT-registered businesses must be able to receive electronic invoices from September 2026, with no size exemption. The obligation to issue is staggered by company size, large companies and mid-caps first, then SMEs and micro-businesses, through to September 2027.

How long should you allow?

Two to four months for a single-site micro-business, four to eight months for a multi-site SME or one with an ERP to connect. The diagnosis takes two to three weeks, selecting and configuring the platform about a month, and you should keep a few weeks of parallel running before the full switchover.

Is a PDF enough to be compliant?

No. A compliant electronic invoice is a structured file in Factur-X, UBL or CII format, transmitted by an approved platform. A PDF sent as an attachment does not meet the obligation, even if it is perfectly readable.
