French e-invoicing: getting your ERP ready before the deadlineReceive since September 2026, issue in September 2027. The calendar will not move again.

Since 1 September 2026, every VAT-registered business in France must be able to receive electronic invoices through an approved platform. On 1 September 2027, SMEs must also issue them in a structured format and report certain data to the tax administration. A PDF sent by e-mail will no longer do. The question is not whether to start, but how to do it without breaking your management software.

Your situations

What we hear from SMEs

"Our invoicing software is ten years old and the vendor no longer answers."

"We received three proposals from approved platforms and cannot tell the difference."

"Our invoices come out of Excel and a Word template."

"Our ERP is custom-built, nobody knows whether it can produce Factur-X."

"The accountant says choosing the platform is up to us."

"We do not know what e-reporting is or whether it applies to us."

What we deliver

What we do

Diagnosis of your invoicing chain

Where your invoices come from, in what format, to whom, and what your software can produce today. Half a day, one document, a list of what is missing.

Choosing the approved platform

There are about 150. We compare those compatible with your software and your accountant, on real cost and interoperability, with no commission from any vendor.

Connecting your ERP

Generation of structured formats, Factur-X, UBL or CII, sending and receiving through the platform, processing statuses, e-reporting. On Odoo, Dolibarr, Sage or a custom ERP.

Operations and monitoring

A rejected invoice, a stuck status, a format change: we watch the flows as part of our managed services, so you do not learn about the problem from your customer.

How it works

A realistic timeline before September 2027

01
This quarter: diagnosis
Map of your invoicing flows, formats produced and received, software involved, monthly volume. You know where you stand.
02
Then: reception in place
Registration on an approved platform, reception and integration of supplier invoices into your tool. This is already mandatory.
03
Early 2027: issuance in test
Your ERP produces structured invoices, tested with a few volunteer customers and your accountant.
04
Before September 2027: switch-over
General issuance, e-reporting configured, written procedure for special cases, exports, credit notes, foreign customers.

What the reform requires, plainly

Receive: since 1 September 2026, all businesses, micro-enterprises included, must be able to receive electronic invoices through a State-approved platform.
Issue: large and mid-sized companies since September 2026, SMEs and micro-enterprises from 1 September 2027, for any invoice to a French VAT-registered business.
Format: a structured file, Factur-X, UBL or CII. A plain PDF is no longer an electronic invoice in the legal sense.
E-reporting: for sales to consumers or abroad, certain transaction data must be sent to the administration, even without an electronic invoice in return.

The official details are on impots.gouv.fr, with the list of approved platforms, the only authoritative one.

The role of the approved platform

The approved platform is the mandatory intermediary: it receives, transmits and checks your invoices, manages statuses and e-reporting. All platforms are interoperable, you are free to choose, and your customer may use a different one. What matters for an SME is compatibility with your software, with your accountant, and the cost per invoice.

What your ERP must be able to do

Produce an invoice in a structured format, with the mandatory details and your customer's identifier in the national directory.
Send that invoice to your platform and receive the statuses back: filed, rejected, refused, paid.
Integrate received supplier invoices, without retyping.
Transmit e-reporting data when required.

If your software is off the shelf, the vendor normally has an answer: we verify it with you. If it is custom-built, it is development work, and that is our job.

The hidden upside of the reform

A structured invoice can be read without retyping. A company receiving its supplier invoices in Factur-X can reconcile them automatically with its orders, have them checked by an AI agent before validation, and follow its collections in real time. The regulatory constraint is also a chance to remove data entry nobody likes doing.

What we learned on our own ERP

Kapsloc develops and operates its own management software, with invoicing, accounting and bank reconciliation. We added AI checks on accounting entries and we are preparing e-invoicing there like any SME: that is what lets us talk concretely about formats, statuses and special cases.

Frequently asked questions

Questions we are asked

We are a small business, are we affected?

Yes, as soon as you are VAT-registered, even under the exemption scheme. Reception has been mandatory since September 2026 for everyone, issuance for SMEs and micro-enterprises from September 2027. Only transactions with consumers or abroad escape e-invoicing, and they fall under e-reporting.

Which approved platform should we choose?

The one that talks to your software and your accountant, at the best cost per invoice. There are about 150, all interoperable; some management-software vendors are approved themselves. We compare three options suited to your case, with no commercial link to any.

Our ERP is custom-built, what is needed?

Adding the generation of a structured format, usually Factur-X, the connection to your platform's API for sending, receiving and statuses, and the integration of received invoices. It is a few weeks of work, which we did on our own ERP.

Do we need to change software?

Not necessarily. If the vendor has a clear answer and a timeline, we verify it and put it in place. If the vendor has no answer, or the software is abandoned, it is time to talk seriously, but nobody changes ERP in six months under duress.

What happens if we are not ready in September 2027?

Your invoices to French businesses will no longer be admissible under the reform, with fines per invoice and a risk of rejection by your customers. The real risk is commercial: an equipped customer will refuse a PDF. Starting with reception, already mandatory, is the best way not to be caught out.

Where does your invoicing chain stand?

Thirty minutes to map your flows and know what is missing before the deadline.
