2026 E-Invoicing for Construction: Factur-X Guide

All construction companies subject to VAT in France are affected by business-to-business electronic invoicing. Once the reform comes into force, they will all have to be able to receive an electronic invoice, whatever their size. The obligation to issue is phased in: large companies and mid-sized companies (ETI) go first, followed by SMEs, very small businesses and micro-enterprises.

Key takeaways Receiving electronic invoices is mandatory for all construction companies, from the solo mason to the general contractor, as soon as the reform comes into force. Issuing is phased in: SMEs, very small businesses and micro-enterprises have extra time compared with large companies and mid-sized companies (ETI). An electronic invoice is a structured file, not a PDF sent by email. The reference format is Factur-X. Invoices travel through a partner dematerialization platform (PDP) registered by the tax administration. Construction calls for particular attention: reverse-charge VAT, progress invoices and retention must remain readable in the structured format.

In practice, no professional can wait for the last deadline. Even a craftsperson with a few employees will have to be able to receive an electronic invoice before having to issue one. Receiving already means being connected to a platform and having updated one's company data. It is better to deal with the subject early than in a rush. Our 2026 electronic invoicing checklist details the steps to follow.

An electronic invoice is not a PDF sent by email. It is a structured, machine-readable file. The reference format in France is Factur-X: a hybrid file that combines a human-readable PDF with XML data that can be processed automatically. The UBL and CII formats are also accepted.

To circulate, these invoices go through a partner dematerialization platform (PDP), registered by the tax administration. The PDP issues, receives and guarantees the formats. Each company will have to choose one, or rely on an invoicing tool that connects to one, such as an invoicing management solution for construction. The public invoicing portal, originally intended to play this role free of charge, has been refocused: PDPs are now the ones that handle transmission.

E-reporting completes the system. It consists of sending the tax administration data on transactions not covered by electronic invoicing, such as sales to individuals and transactions with foreign countries, as well as payment data. The stated aim: to pre-fill VAT returns and limit fraud.

Construction combines cases that put invoicing tools to the test. Subcontracting remains subject to the reverse-charge VAT mechanism: the subcontractor invoices without VAT, and the contractor declares and pays the VAT. The "Autoliquidation" (reverse charge) mention will have to appear in a properly tagged electronic invoice, and no longer as a simple free-text line.

Progress invoices, down payments and invoicing on a percentage-of-completion basis continue to apply. A progress invoice shows the cumulative work completed since the start of the contract, less previous progress invoices: this mechanism must remain readable in the structured format. Retention, whose rate is set by law, and its possible replacement by a bank guarantee, will also have to appear clearly.

These rules apply to all trades, including an electrician invoicing on a percentage-of-completion basis on a subcontracted job. The companies concerned will find guidance on the solutions for electricians page.

Finally, each invoice will follow a lifecycle with statuses (submitted, rejected, paid…). For a construction company, this is good news disguised as a constraint: payment tracking, long done by guesswork, becomes traceable from end to end.

First reflex: check that your invoicing tool can produce and read Factur-X, or plan to change it. A standard PDF sent by email will no longer be enough, even between craftspeople.

1. Check that your invoicing tool produces and reads Factur-X. 2. Choose your partner dematerialization platform and make sure it is registered by the tax administration. 3. Make your company data reliable: SIREN (the company identification number), bank details, VAT regime. 4. Update your quote and invoice templates with the new mentions: customer's SIREN, delivery address, nature of the transaction. 5. Train the person who does the invoicing.

Company data will feed the central directory that routes invoices. One wrong piece of data, and the invoice does not arrive. Well prepared, the reform reduces re-entry of data, speeds up payments and makes VAT more reliable. To dig into a specific point, the compliance checklist details each step.
