What is an electronic invoice?

An electronic invoice is an invoice that has been issued, transmitted and received in a digital format, thanks to a fully automated invoicing process. An electronic invoice is only valid if the issuer is formally identified, its content cannot be edited, and it is legible and complete. Like paper invoices, electronic invoices must include certain mandatory information.

Docaposte offers the most complete range of services on the market for processing your supplier and customer invoices, adapted to the needs of all organisations, from small businesses to large groups.

What are the advantages of electronic invoicing?

Implementing electronic invoicing for your suppliers and customers offers a number of advantages over traditional paper invoicing, including lower costs and faster processing time within a secure and reliable environment. Furthermore, it will mean you are ready for the upcoming French electronic invoicing regulations.

The Docaposte solution provides all the benefits of electronic invoicing:

  • Guaranteed process safety and improved traceability through automated validation and control systems
  • 30% increase in productivity thanks to automated data entry and control
  • Process automation cuts processing, printing, sending and archiving costs by 50 to 75%.
  • Smoother relations between customers and suppliers.

Regulations/rules on the dematerialisation of invoicing

Already in place for the public sector since 2020, the e-invoicing obligation will soon be extended to B2B exchanges between VAT-registered companies and associations established in France. Ultimately, this reform of electronic invoicing will simplify business processes, reduce payment times and combat VAT fraud.

The reform will take place in two stages:

  • From September 1, 2026: receipt obligation for all companies and an emission obligation for large and mid-sized companies.
  • From September 1, 2027: emission obligation for small and medium-sized enterprises and microenterprises.

Given the stakes for businesses, these entry into force dates may be adjusted by one quarter to ensure reliable deployment.

Frequently Asked Questions About Electronic Invoices

  • An e-invoice is an invoice that has been issued, transmitted, and received in a structured electronic format that allows for automated and electronic processing.

    This makes it possible to process in a simplified and structured manner exchanges between customers and suppliers of small and medium-sized businesses (TPE / PME), mid-sized businesses (ETI) or large businesses (GE). An e-invoice has the same legal value as a paper invoice, but requires the entire process to be conducted electronically and through certified applications. Just like the classic paper invoice, it must also contain all the mandatory information required.



  • To create an e-invoice, it is necessary to equip yourself with a suitable tool which allows you to easily edit any invoice and which must comply with French legislation.

    An e-invoice should not be confused with a dematerialized (paperless) invoice. It must include the same mandatory information as a paper invoice:

    • Date
    • Identity of the issuer and recipient
    • Invoice number / client's SIREN number
    • Description of the product or service
    • Quantity
    • Date of sale
    • Amount excluding tax and including tax, and penalties for late payment
    • VAT number and rate
    • Legal notices

    Docaposte's electronic invoice solution will guide you through all of these steps. You can also speed up this process by adding an electronic signature and an electronic archiving system (EAS) of your invoices.


  • An invoice can be certified as compliant through:

    • By means of an electronic signature authenticated using a qualified electronic certificate.
    • By establishing one or more controls that create a reliable audit trail, tracing the relationship between the invoice and the delivery of goods or provision of services.
    • In the form of a message structured in accordance with a security standard previously defined by the parties involved, allowing automated interpretation. This structuring can be carried out through different means such as integrated management software packages (ERP), electronic data interchange (EDI), XML format, sending by email with a PDF file attached, or even receiving a fax in electronic form, for example.

    All the conditions for an invoice to be certified as compliant have been further specified with the introduction of the VAT Fraud Prevention law on January 1, 2018.

  • All businesses subject to VAT in France are affected by electronic invoicing. The implementation of electronic invoicing will be gradual according to a schedule defined by the upcoming Finance Law for 2024.

  • A partner dematerialization platform (PDP) is a trusted and secure third party specialized in the processing, receipt, and transmission of electronic invoices, having undergone a registration procedure with the French administration. These platforms ensure the continuity and reliability of the invoicing processes.
