Updated on May 10, 2024

The European Union has laid the foundation for e-invoicing in public procurement with Directive 2014/55/EU, in which the Peppol network (Pan-European Public Procurement On-Line) plays an important role. This network ensures a secure and standardized exchange of electronic documents between companies and governments.

Certain obligations for e-invoicing are also expected for SMEs in Belgium:

  • European Standard: E-invoicing must comply with the European standard, which means that invoices are sent in a standardized (XML/UBL2.1) format and no longer as PDF.
  • Peppol Network: The use of Peppol is encouraged for electronic transmission of invoices between companies and governments. This network provides standard protocols and ensures interoperability.
  • Government contracts: SMEs that work with the government are already obliged to send e-invoices via Peppol.

However, these obligations differ per country and may depend on the size of the SME. For Belgium, you can find a nice article about PEPPOl & e-invoicing through KROTON Accountancy.

The purpose of electronic invoicing via PEPPOL is to ensure a more efficient operation for the exchange of important documents. This allows invoices to be processed faster, or if something is missing such as a PO number or a reference, the invoice is automatically returned with a message that something is still missing. This way you can be sure that the recipient actually receives your invoice when it was received and that everything on the invoice is correct to make a payment.

Both sender and recipient can also access all exchanged invoices via the PEPPOL network. This means you have lower follow-up costs because the processing of the invoices happens automatically.

There is also compliance according to European and national regulations, which means that all invoices are put in a standardized format.

We recommend that you seek guidance in a timely manner and register your company on the PEPPOL network. So that you don’t have to register for this in a hurry. With the right guidance, you can switch systems in no time.

Why Peppol is important for SMEs in Belgium

More specifically for Belgium, e-invoicing will become mandatory for government contracts. The Belgian government requires that all suppliers send their invoices via Peppol.

SMEs that already use Peppol and e-invoicing can work more efficiently and are better prepared for future legal requirements. We can only recommend that you prepare yourself for this before you suddenly receive your first electronic invoice and you suddenly have to connect your company to the Peppol network.

Electronic invoicing is currently only mandatory for invoices to and from the government, but it will soon also become the standard for all B2B invoices and documents exchanged between companies.
