Starting 2026, all invoicing between Belgian companies has to be done through the Peppol network. If you are already registered with Peppol, you can start receiving your utility bills as e-invoices. With Luminus, it’s quite simple. You just need to fill in an online form. This simple guide explains how to do this.
What do you need to do to receive e-invoices from Luminus?
It’s very straightforward: as a business customer with Luminus, you can activate e-invoicing by filling out this form. However, be sure to register with Peppol first. Here’s how you do it.
Once activated, your invoices will automatically appear in your invoicing software. Additionally, you’ll still receive an email each time your energy invoice is ready, or you can opt to receive one email containing all your invoices.
What are e-invoices?
An e-invoice is not the same as a PDF or a scanned invoice. E-invoicing specifically involves XML files sent in the UBL format via the Peppol network. Thanks to these UBL standards, all the necessary information is included on the invoice, allowing accounting or invoicing software to read it.
Such invoicing software can send, receive, and automatically process e-invoices. In some cases, you can also choose to have the invoices automatically paid through the software.
