This page presents a description of the rules and solutions for Electronic Invoicing (e-invoicing, e-billing) and Invoice and VAT reporting (e-reporting).

The laws, rules, and solutions to read, generate and/or send e-invoice depend on your country...

If your country is not in this list, feel free to develop your own interface module and publish it on any git source repository or packaged as a zip (for the price of your choice) on dolistore.com. But you can also do it as an alternative of an existing solution if a module already exists and does not match your need...


Belgium (Peppol BIS Billing 3.0)

The electronic invoice format in Belgium is Peppol BIS Billing 3.0, which uses the UBL structure defined by the OASIS organization: https://docs.oasis-open.org/ubl/

France (Factur-X, Peppol BIS Billing 3.0)

Format

The government has specified three types of electronic invoice formats:

  • Factur-X, sometimes incorrectly written as FactureX (Hybrid Format PDF A/3 + Structured Data in XML included in the PDF)
  • CIUS for Chorus Pro (Cross Industry Invoice (CII))
  • Peppol BIS Billing 3.0 (Universal Business Language (UBL) format)

Any of these formats can be used in France. The Dolibarr software has chosen the first format. It is already compatible (see below).

Timeline

Initially, the first deadline was set for January 1, 2024. The schedule was modified at the end of 2023 by the government. It is now as follows:

  • From September 1, 2026: Obligation to receive electronic invoices for all businesses.

All companies are required to receive their invoices in electronic format. Only large companies (employing at least 5,000 employees or with a turnover exceeding 1.5 billion euros) and medium-sized companies (employing between 250 and 4,999 employees or with a turnover not exceeding 1.5 billion euros) are required to issue invoices in electronic format.

  • From September 1, 2027: All SMEs and micro-enterprises will be required to issue electronic invoices (postponable until December 1, 2027).

Dolibarr support

To generate invoices in the Factur-X format, you need to install the FacturX module available on Dolistore:

This module, or a modified or Dolibarrized version of the module, will be integrated as standard in a future version of Dolibarr.

Once the document is generated, it must be transmitted to a centralized platform. Sending the invoice directly to your client via email will no longer be possible.

Dolibarr, like any invoicing software, will therefore need to interface with a PDP (private intermediary operator) or the PPF (the state's centralized platform for submitting invoices). This point has not yet been developed because the government platform and specifications for such automatic invoice transfer are not yet ready. The development will be carried out as soon as they are available. See the page GIFF Facture électronique.


Note: France already offers a platform called Chorus-Pro, where it is mandatory to submit invoices in certain cases (e.g., invoices intended for the administration). To interface your Dolibarr with this platform, you need to either submit invoices manually onto this platform, or to use a third-party service for submission directly from Dolibarr, for example by using:

Germany (Factur-X / ZUGFeRD, Peppol BIS Billing 3.0)

Format

The electronic invoice format in Germany is Factur-X, which is the same as in France. However, its German name, ZUGFeRD, can also be used. This standard involves integrating structured invoice data into an XML file embedded within the PDF A/3 of the invoice. All authorities at federal and national level are mandated to always offer a Peppol transmission if an automated data exchange is provided for the delivery of eInvoices. The XRechnung format being specific to Germany, economic operators should select a provider that is accredited by the German Peppol Authority. This ensures that the service provider conducts Peppol transactions in Germany.

Timeline

  • Mandatory issuance of eInvoices for companies with an annual turnover exceeding 800 000, 00 EUR. In 2027
  • Mandatory issue of eInvoice for every B2B transaction in 2028

Spain (FacturaE - VeriFactu)

Format

The electronic invoice format in Spain is called FacturaE (European standard EN 16931). VeriFactu is the system and network to send and validate invoices.

Timeline

B2B: The Law 18/2022 amendment mandates that all B2B transactions must be conducted using eInvoices. Businesses with annual revenues of EUR 8 million or more must comply within one year, while others have a two-year compliance period but it has not been officially issued yet.

Effective on 1 January 2026, the VERIFACTU system will become mandatory for all companies that are not subject to the SII Reporting mandate. This will require these companies to use certified accounting software and obtain invoice clearance for all their transactions.

Dolibarr support

One of the following module is required:

  • Module DoliFactu

A module called 2FacturaE exists to generated invoices using the invoice in the format expected (https://www.2byte.es/index.php/productos/modulo-2facturae). It was enough for spain.

But this is no more true: In 2025, you must also now have a software that keep tracking of recording payment and invoices into an unalterable way. For this you need now the module DoliFactu (https://dolifactu.es/producto/modulo-antifraude-dolibarr/).

Note also that there is also a ready to use hosting service called DoliFactu.es that includes this module by default in its offer.

  • Module LeyAntiFraudeYVeriFactu

Another solution to be ready and compliant with the VeryFactu system is to install the external module called "Ley antifraude y VeriFactu"

You can get the module here: https://www.dolistore.com/fr/modules/2259-Ley-antifraude-y-VeriFactu.html?search_query=verifactu&results=1

Note: As the law is evolving frequently and may depends on your business, you MUST check with your book keeper or your laywer that this suits completely the law and the need of your own business.

Legislation and current status


Switzerland (QR-Bill)

Format

  • E-reporting:

Until 2022, Switzerland required invoices to be accompanied by a red payment slip (called BV) and an orange payment slip (called BVR). This is no longer the case. Instead, PDF invoices in Euro or Swiss Francs, which can or must be paid by bank transfer, must include, at the bottom of the page for example, a section containing all the information required for payment by transfer. This is called the QR-Bill or QR-Invoice.

Timeline

The "red payment slip" (called BV) and an "orange payment slip" (called BVR) is no more required after 2022.

QR-Bill is expected for PDF invoices in Euro or Swiss Francs, which can or must be paid by bank transfer since the 20th june 2020.

Dolibarr support

To obtain such a section:

  • You can install the following module: https://www.dolistore.com/fr/modules/286-SwissBanking.html
  • The other option is to activate the experimental option INVOICE_ADD_SWISS_QR_CODE:
    • Setting the value to '1' will generate and print the QR code only.
    • If the option is set to 'bottom', the entire section at the bottom of the invoice will be displayed, but the installation of an external PHP library will be requested at the first generation of the PDF.
