Step-by-step guide to receiving electronic invoices from Proximus

To be able to receive e-invoices from Proximus, the first thing to do is register on Peppol. You’ve already done that? Super, let’s continue.

Not registered on Peppol yet? Then start here: how do I sign up for Peppol?

To receive your Proximus invoices fully electronically via Peppol, the following criteria must be met:

• You must have added your phone, internet or TV to MyProximus.
• You must register and log in with an administrator account to be able to consult your invoices.
• You must have invoicing software like Accountable.

If all these criteria are met, follow the steps below to activate electronic invoicing at Proximus.

1. Open the Proximus+ app or log in to the website.
2. Click on ‘MyProximus’, go to the settings, and then to ‘Bill settings’. 
3. In the choices for receiving your bill, select ‘Peppol’.

If everything works as it should, Peppol will be displayed as checked and in green. From now on, you’ll receive all your Proximus invoices in electronic format via Peppol.

You’re informed via email each time a new invoice is sent, and these remain available for 24 months via MyProximus.

⚠️  Note that the above method is only for Proximus professional accounts. Are you a self-employed sole trader and don’t have a professional account with Proximus? In this case, you won’t be able to receive your electronic invoices via Peppol. To receive your invoices via Peppol as a self-employed individual, contact Proximus to have your personal account converted into a professional account.

What exactly is electronic invoicing?

As a reminder, an electronic invoice isn’t the same thing as a digital invoice. A PDF invoice is a digital invoice, but it is not considered an electronic invoice.

Electronic invoices, or e-invoices, are XML files that are transferred in UBL format via the Peppol network. These UBL standards ensure that all the required information is included on the invoice and that it can be read by accounting or invoicing software.

These software programs can automatically create, receive, and even process electronic invoices. It’s even possible to authorise them to pay invoices automatically.

💡 Accountable tip: You can use Accountable to receive and send electronic invoices via the Peppol network, including in the free version. Try Accountable now.
