E-invoicing for foreign clients: does the obligation apply?

You regularly invoice clients in the Netherlands, France or another EU country. Do you also need to send them e-invoices via Peppol? Or does the Belgian obligation only apply to domestic clients?


The short version

The Belgian e-invoicing obligation only applies to transactions between two Belgian VAT-registered businesses. If your client does not hold a Belgian VAT number, you are not required to send a Peppol invoice.

For foreign clients, you may therefore continue to send a PDF invoice by e-mail, just as you did before.


But there are nuances

Client has both a Belgian and a foreign VAT number

Some international companies have a permanent establishment or entity in Belgium and are therefore also Belgian VAT-registered. In that case, the obligation does apply to your invoices to that Belgian entity, even if the parent company is based abroad.

Client requests an e-invoice themselves

More and more European countries are introducing their own e-invoicing obligations — the Netherlands, Germany, France and others are working on similar legislation. Your foreign client may ask you to send an e-invoice, even if you are not legally required to do so.

Peppol is a European network, so if you are already connected, you can in principle also invoice foreign clients via Peppol — provided they are also registered on the network.

Intra-Community supplies and exports

For invoices where VAT is reverse-charged to the client (intra-Community supplies) or where a VAT exemption applies (exports outside the EU), the existing rules continue to apply. These invoices do not need to be sent via Peppol.


In summary

  • The Belgian e-invoicing obligation only applies to B2B transactions between Belgian VAT-registered businesses
  • Foreign clients without a Belgian VAT number: sending a PDF by e-mail remains permitted
  • Foreign companies with a Belgian entity: Peppol is required
  • Peppol is European — you can also use it for foreign clients who request it

No. The obligation only applies to transactions between two Belgian VAT-registered businesses. You may still send a PDF by email to customers without a Belgian VAT number.

Invoices to that Belgian entity do fall under the Peppol obligation, even if the parent company is foreign.

Can I use Peppol for foreign customers?

Yes, Peppol is a European network. If your foreign customer is connected, you can invoice them via Peppol — more and more EU countries are introducing their own e-invoicing obligations.
