2026 e-invoicing: the checklist for construction businesses

The reform applies to all transactions between businesses liable for VAT in France. Two dates structure the timeline. On 1 September 2026, receiving electronic invoices becomes mandatory for every business, whatever its size — from the sole-trader bricklayer to the largest contractor. On the same date, issuing them becomes mandatory for large companies and mid-cap firms.

Small and micro construction businesses have until 1 September 2027 to issue their invoices electronically. In other words, even a three-person craft business will have to read an electronic invoice from 2026, before issuing one itself a year later.

The scope covers domestic business-to-business (B2B) invoices. Transactions with private individuals (B2C) and abroad fall under e-reporting: the transmission of transaction data to the tax authority.

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

To circulate, these invoices pass through a Partner Dematerialisation Platform (PDP), accredited by the tax authority. The platform transmits, receives and guarantees the formats. Every business will have to choose one, or rely on an operator connected to it.

E-reporting completes the system: it transmits to the authority the data of operations not covered by e-invoicing (sales to individuals, exports) and payment data. The aim is to pre-fill VAT returns and curb fraud.

The reform adds mandatory details that many quote-and-invoice tools do not yet handle. Among them: the client's SIREN business number, the delivery address when it differs from the billing address, and the nature of the operation (supply of goods, provision of services, or both).

Construction has its own specifics. Subcontracting remains subject to the VAT reverse charge: the subcontractor invoices excluding tax, and the main contractor declares the VAT. The 'Autoliquidation' wording will have to appear in a properly tagged electronic invoice, no longer as a simple line of text.

Progress billing, down payments and the retention guarantee still apply. Each invoice will also follow a status-based lifecycle (deposited, rejected, paid…), a novelty that formalises payment tracking.

First reflex: check that your invoicing tool will be able to produce and read Factur-X, or plan to switch. A standard PDF will no longer be enough.

Next, choose your Partner Dematerialisation Platform and make sure it is properly accredited. Fill in your company data (SIREN, bank details, VAT scheme), as it will feed the central directory.

Finally, update your quote and invoice templates to include the new details, and train whoever does the billing. The reform is not just a technical constraint: well prepared, it cuts re-keying, speeds up payments and makes VAT more reliable. Better to tackle it in 2025 than in the rush of summer 2026.
