The electronic invoicing reform marks one of the biggest administrative and financial transformations in recent years. Starting in September 2026, all French companies will need to be able to receive structured electronic invoices and then issue them via approved platforms.

For SMEs — particularly those generating between 5 and 30 million euros in revenue — this reform is a challenge: organization, internal processes, tools, teams, compliance… And yet, it is also a tremendous opportunity to improve the productivity and financial reliability of the company.

Here is what leaders must absolutely understand before 2026.

1. What is the electronic invoicing reform?

The reform will require all VAT-registered businesses to  :

Receive electronic invoices in a structured format (mandatory from September 2026)Accepted formats:

Factur-X

• UBL
• CII
• To

issue these invoices via an approved platformIssuance will become mandatory in phases (depending on size), after 2026.

To transmit certain information to the tax administration (e-reporting)

This concerns:

international sales,

• B2C sales,
• transactions outside the e-invoicing scope.
• What will no longer be compliant ❌

A

PDF invoice sent by email will no longer be validIt will be systematically rejected..

​

2. Who is concerned?

100 % of companies subject to VAT :

• Micro-enterprises
• SMEs
• Mid-sized companies
• Groups
• Liberal professions
• Taxed associations

Even companies that are already highly digitalized (ERP, EDI, automation) will need to adapt their flows to the new standards.

3. The official reform schedule

September 2026

Obligation for all companies to receive electronic invoices.

Issuance 

(dates adjusted by the DGFiP  gradual deployment)

By company type, according to size and maturity.

4. How does the new system work ?

Three actors interact :

1. The PPF – Public Invoicing Portal (administration)

• Receives the flows
• Controls compliance
• Transmits VAT data

2. Approved Platforms (PA)

Formerly PDP (Partner Dematerialization Platforms).

Role :

• send and receive invoices
• convert formats
• ensure compliance

3. Dematerialization Operators (OD)

• Service providers interconnected to the PAs
• Facilitate the flow between business tools (CRM, ERP, accounting)

An SME will need to choose a PA and set up the interconnection with its information system.

5. The concrete impacts for a SME (5 to 30 M€ revenue)

The reform is not just a change of format. It impacts the entire organization.

Impacts organisationnels

• new management of ADV / billing flows
• modification of internal validation circuits
• transformation of team habits
• new rules for supplier accounting

Impacts informatiques

• compliance of the ERP
• connection to a PA platform
• management of APIs / connectors
• new data formats

Impacts financiers

• risk of rejected invoices
• risk of payment delays
• opportunity to automate flows
• possible improvement of cash flow

6. The risks if your SME does not anticipate

• Invoice rejections: loss of time, delays in collection
• Double entry or series errors
• Emergency costs (implementation in a hurry)
• Internal disorganization
• Non-compliance and sanctions
• Tensions between ADV, finance, and IT

👉 For a small and medium-sized enterprise, waiting until 2026 is risky, especially during a period of overload.

7. An opportunity to modernize and gain productivity

This reform is also a lever for:

• ✔ automate financial processes
• ✔ éliminer les ressaisies manuelles
• ✔ ensure the reliability of accounting
• ✔ speed up customer payments
• ✔ incorporate the flows into the financial reporting
• ✔ streamline the relationship with the accountant or CFO

SMEs that anticipate will gain a competitive advantage.

Issuance, validation, sending, receiving, accounting.
