e-Invoicing for your BASE invoices

Important

From 1 January 2026, all Belgian companies registered for VAT will be required to send and receive electronic invoices. To this end, all companies with a Belgian VAT number must register on the Peppol network. Do you have a foreign VAT number? Then electronic invoicing is not mandatory.

What are Peppol and electronic invoicing?

Peppol (Pan-European Public Procurement Online) is the network that enables companies to exchange electronic invoices. An electronic invoice is an invoice created in a legally predetermined format. This format allows invoices to be sent automatically via Peppol and read and processed immediately by compatible invoicing software on your computer.

How can you link your electronic invoicing to BASE?

Do it in two steps:

1. Register with Peppol

  • Register your company on the Peppol network. 
  • You can do this via your invoicing or accounting software. Alternatively, contact your accountant. 
  • Not sure if your company is already registered? Check via the Peppol Directory.

2. Link your electronic invoicing to BASE

  • Go to My BASE and choose Peppol as as how you receive your invoices.
  • From now on, you will receive all your invoices and credit notes exclusively via the Peppol network.
  • Is a new e-invoice available on Peppol? We’ll let you know by email and/or SMS.
  • We will no longer send your documents by email or by post.

Good to know: if your next invoice is already being prepared when you change your delivery method, you will receive it one last time using the previous method.

You will always have an overview via My BASE

You can find a summary of all your invoices in My BASE.

Please note!
From 2026, electronic invoicing will be the only legal document. This means that you will no longer be able to use PDF invoices from My BASE for accounting or VAT returns.

Any other questions?

Yes, Peppol is mandatory for all Belgian VAT-registered companies. It is therefore important to take the necessary measures in good time. If you don't, you risk a tax penalty and may not be able to recover certain costs.

No, it's not always free. Some software solutions are free, while others incur a cost.

Most of the time, this happens because of a technical issue. If that’s the case, we’ll notify you. As soon as the issue is resolved, your e-invoice will automatically be available on Peppol. Did you know you can always find an overview of all your invoices in PDF format in My BASE? This allows you to arrange your payment right away. Please note that as of 2026, the PDF document will no longer be considered an official document and cannot be used for your accounting or VAT declaration.
