Electronic invoicing calendar: all deadlines 2026-2027

The reform of electronic invoicing is part of a progressive, but restrictive timetable. Two dates structure the entire system: September 1, 2026 And September 1, 2027.

This apparently simple division actually imposes an anticipated increase in workload for all companies.

A two-step implementation

The timetable is based on a logic of progressive extension:

  • 2026: entry into the system (receipt required)
  • 2027: generalization of the emission

This sequencing should not be interpreted as a delay. Rather, it marks the different stages of the same shift.

September 1, 2026: all companies must be able to receive

From this date, all companies subject to VAT must be able to receive electronic invoices.

This concretely implies:

  • be connected to a approved platform
  • be referenced in thecentral directory
  • be able to integrate invoices into its systems

Even without an obligation to issue at this stage, no company can remain outside the system.

What changes from 2026

  • receipt of invoices only via the system
  • gradual disappearance of off-platform shipments
  • adaptation of accounting and financial tools

The key point: connection becomes compulsory for everyone.

September 1, 2026: emission obligation for large companies and ETIs

At the same time, some companies will have to take an additional step.

Are concerned:

  • THE large companies
  • THE ETI (mid-sized companies)

They must:

  • issue their invoices in electronic format
  • transmit them via an approved platform

This first perimeter plays a role in priming the system.

September 1, 2027: generalization of the broadcast

One year later, the obligation extends to the entire economic fabric.

Are now concerned:

  • THE SMEs
  • THE TPE
  • THE micro-entrepreneurs

From this date:

  • all B2B invoices must be issued electronically
  • all actors must be fully integrated into the system

The changeover becomes complete.

Summary of the calendar

Date Companies concerned Obligation
September 1, 2026 All Reception
September 1, 2026 Large companies + ETI Emission
September 1, 2027 All Emission

This table summarizes the logic, but does not fully reflect the operational implications.

A ramp-up from 2025

In fact, preparation does not begin in 2026.

Companies must anticipate now:

  • choosing a platform
  • tool upgrade
  • data structuring

Publishers, accountants and integrators are already engaged in this transition phase.

Waiting until 2026 amounts to intervening in a system already in operation.

The case of micro-entrepreneurs and small structures

The reform also concerns the lightest structures.

A micro-entrepreneur subject to VAT must:

  • be able to receive from 2026
  • issue electronically from 2027

Even with limited billing volume, technical integration remains necessary.

What remains allowed during the transition

The transition to all electronics is gradual.

During the transitional phase:

  • certain representations in PDF may remain
  • but they must be backed by structured data
  • and circulate via the platforms

The PDF becomes a display, no longer a channel.

A broader reading of the calendar

The calendar is not limited to a series of dates.

It organizes:

  • the gradual entry of companies into a common system
  • the rise of platforms
  • alignment of practices

Behind these deadlines, a synchronization of the economic fabric is taking place.

A short timetable, lasting impacts

Between September 2026 and September 2027, all French companies will switch to a new invoicing model.

The time frame is short on the scale of the necessary transformations:

  • redesign of tools
  • technical integration
  • process adaptation
