E-Invoicing 2026 for Construction: The Checklist

The reform applies to all companies subject to VAT in France, for their invoices exchanged between businesses. On 1 September 2026, all construction companies, whatever their size, must be able to receive electronic invoices. On the same date, large companies and ETIs (mid-sized companies) must also issue them, while SMEs, very small businesses and micro-enterprises issue them from 1 September 2027.

Who is affected in construction?

The scheme targets all companies subject to VAT, meaning those that charge VAT or deduct it. In construction, this covers the solo mason as well as the major construction group, the electrician, the plumber, the plasterer or the roofer. Company size does not change the receiving obligation: a craftsperson with three employees must be able to read an electronic invoice from 1 September 2026, before having to issue one a year later.

In practice, receiving concerns the invoices sent to you by your suppliers and subcontractors: building materials merchants, equipment rental companies, firms in neighbouring trades. They will no longer arrive by simple email with a PDF, but through a secure channel and in a structured format.

Which transactions are in scope?

The scope covers invoices between businesses (B2B, for "business to business") carried out within French territory. Transactions with private individuals (B2C, for "business to consumer") and transactions with other countries fall under e-reporting, that is, the transmission of transaction data to the tax authority.

For a renovation company that works both for private individuals and for property managers or developers, both regimes coexist. Jobs for private individuals fall under e-reporting, while jobs invoiced to a business fall under e-invoicing. This distinction must appear in your invoicing tool, which must know which flow to attach each document to.

Why receiving comes before issuing

The staggered timeline gives small businesses an extra year to issue, but it requires them to prepare to receive from 1 September 2026. A company that has not chosen its receiving platform risks being unable to process its suppliers' invoices normally. Starting with receiving also helps you get familiar with the format before having to produce it.

An electronic invoice is not a PDF sent by email. It is a structured, machine-readable file whose information (customer identity, amounts, VAT rates, due date) is placed in standardised fields. A standard PDF remains a simple image of the document: software cannot reliably extract the data from it.

Factur-X, UBL and CII: the accepted formats

The reference format in France is Factur-X: a hybrid file that combines a PDF readable by the human eye and XML data that can be processed automatically. XML is a markup computer language that allows software to find each piece of information in its place. The UBL (Universal Business Language) and CII (Cross Industry Invoice) formats are also accepted.

The three accepted electronic invoice formats Format | Composition | Readable by the naked eye Factur-X | PDF and XML data in a single file | Yes, thanks to the embedded PDF UBL | Structured XML data | No, a reading tool is needed CII | Structured XML data | No, a reading tool is needed Source: electronic invoice formats accepted under the French reform, 2026.

For a craftsperson, Factur-X has a practical advantage: the document keeps the look of a usual invoice, while embedding the data that will be read by the customer's platform.

The PDP, the partner dematerialisation platform

To circulate, these invoices go through a Partner Dematerialisation Platform (PDP, in French Plateforme de Dématérialisation Partenaire), registered by the tax authority. It transmits, receives and guarantees the formats. Each company will have to choose one, or rely on an operator that connects to one, for example its invoicing software. Each company's receiving details are listed in the central directory, which allows a sender to know where to send their customer's invoice.

Always check that the chosen platform is properly registered: a platform that is not registered does not guarantee the compliance of exchanges.

E-reporting: transmitting data outside e-invoicing

E-reporting completes the scheme. It consists of transmitting to the tax authority the data on transactions not covered by e-invoicing, such as sales to private individuals and exports, as well as payment data. The whole aims to pre-fill VAT returns and limit fraud.

For the business owner, the consequence is simple: a construction company's invoicing now directly feeds the data known to the tax authority. A gap between your invoices, your receipts and your returns becomes more visible.

The reform adds mandatory mentions that many quoting and invoicing software packages do not yet handle. Among them: the customer's SIREN number, the delivery address of the goods when it differs from the billing address, and the nature of the transaction (delivery of goods, provision of services, or both). The SIREN is the nine-digit identifier of a company in the Insee register.

The new mentions to include

• The customer's SIREN: it identifies the recipient company and allows the platform to route the invoice. • The delivery address: it must appear when it differs from the billing address, which often happens when the site address is not that of the customer's head office. • The nature of the transaction: delivery of goods, provision of services, or both. On a site that combines supply of materials and installation, the invoice must reflect this dual nature.

The site address deserves particular attention. A client (maître d'ouvrage) may have its head office in one city and build in another. Your tool must therefore clearly distinguish these two addresses from the moment the quote is created, so that they carry over to the invoice without re-entry.

Subcontracting and VAT reverse charge

Construction has its own specificities. Subcontracting remains subject to the VAT reverse charge (autoliquidation): the subcontractor invoices excluding tax, and it is the principal contractor who declares the VAT. The "Autoliquidation" mention (reverse charge) will have to appear in a properly tagged electronic invoice, and no longer as a simple line of text. Software that merely adds a free-text sentence at the bottom of the page will therefore no longer meet this obligation.

For a subcontractor, this means configuring their tool so that the VAT regime is carried by the invoice data, and not by a comment. For a principal contractor, it means knowing how to recognise these invoices on receipt.

Progress payment statements, deposits and retention

Practices specific to construction sites continue to apply. Progress payment statements (situations de travaux) are interim invoices issued according to progress. Deposits are advance payments. The retention (retenue de garantie) is a sum held by the customer until the end of the guarantee period provided for in the contract. These mechanisms remain possible, but they will have to be correctly represented in the structured file.

Each invoice will also have to follow a status-based lifecycle (submitted, rejected, paid…), a novelty that formalises payment tracking. For a business owner, this is useful information: it shows what stage each invoice has reached, without phone calls to find out whether it was received.

The following checklist lists, in order, the actions to take for a construction company. If the 1 September 2026 deadline has already passed for you, the steps remain the same: the receiving obligation applies to all companies subject to VAT.

1. Check your invoicing tool. It must be able to produce and read Factur-X, or you must plan to change it. A standard PDF is no longer enough. 2. Choose your Partner Dematerialisation Platform. Make sure it is properly registered by the tax authority, or that your software connects to one. 3. Fill in your company data. SIREN, bank details and VAT regime feed the central directory: check them before declaring them. 4. Update your quote and invoice templates. Include the new mentions: customer's SIREN, delivery address, nature of the transaction. 5. Check the handling of the reverse charge. If you work as a subcontractor, make sure the VAT regime is carried by the invoice data. 6. Inform your suppliers and customers. Share your company's receiving details with those who invoice you. 7. Train the person who invoices. They must know the statuses of an invoice and how to react to a rejection.

To understand the full framework, the guide to e-invoicing 2026 and the Factur-X format details the formats and obligations. If you are looking for a tool, the invoicing management page describes the quoting, invoicing and payment tracking functions. Installation companies can also consult the solutions for electricians, which present site tracking adapted to this trade.

Key takeaways On 1 September 2026, all construction companies must be able to receive electronic invoices, whatever their size. SMEs, very small businesses and micro-enterprises have until 1 September 2027 to issue their invoices in electronic format. An electronic invoice is a structured file (Factur-X, UBL or CII) that circulates through a registered platform. Site mentions, notably the VAT reverse charge in subcontracting, must be carried by the invoice data.

The reform is not just a technical constraint: well prepared, it reduces re-entry, speeds up payments and makes VAT more reliable. The longer a company waits, the more it deals with these topics in a rush, when its suppliers' invoices are already arriving in the new format.
