From 2026, all invoices between Belgian companies will have to go through Peppol. To get a headstart, you can already register on Peppol and opt for easier and faster invoicing. Then, you’ll be able to send electronic invoices to your customers and receive them from your suppliers. Sounds good? In this article, we cover what you need to do to receive your e-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:
If all these criteria are met, follow the steps below to activate electronic invoicing at Proximus.
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.
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.
To activate electronic invoicing via Peppol with Proximus or another telecom operator, you need to be using invoicing or accounting software. Then, you just have to sign up for Peppol. Registration is simple and free.
Follow these steps to register via Accountable:
It can take a while for your registration to be active. To know if it’s been successful, search for your company name in the Peppol Directory.
Once you’ve completed your registration, you’ll automatically receive electronic invoices from some of your suppliers that use e-invoicing. For others, such as Proximus, you’ll need to activate e-invoicing yourself first. Your invoices will then automatically appear in Accountable’s expenses tab.
Using another telecom operator? Click below to learn more:
Other telecom operators, such as Digi, Mobile Vikings and EDPnet, don’t offer electronic invoicing yet.
We’re keeping a close eye on the situation, but don’t hesitate to contact the relevant customer service yourself to ask if it’s possible to change your billing method.
Here at Accountable, we’re doing what we can to get companies on the right track. Because we all have an interest in accelerating the adoption of electronic invoicing – the time savings will benefit everyone!

Très bien, disponibilité !

C’est hyper clair et le service est impeccable, vous répondez vite. La seule chose que j’ai remarqué qui pourrait être une nouvelle fonctionnalité: avoir la possibilité d’être plus précis au niveau de la détermination de ce qu’on paye pour nos cotisations sociales quand on a choisi un plan d’apurement. Par exemple, 300€ par mois au lieu que le choix soit juste par trimestre.

The coaching session on tax management was excellent, good material, excellent explanations and very insightful…my accountant and tax advisor are good, but never so comprehensive and accurate. Combined with the AI I never feel alone with Accountable

Le contact avec l'equipe ! On n'a pas affaire à un chat avec un robot stupide qui ne comprend rien mais avec des humains et un vrai dialogue

altijd snelle, vriendelijke en professionele service. Ook al heb ik door gebrek aan activiteit weinig gebruik kunnen maken van uw diensten. Gisteren heb ik het contract opgezegd, en ook dat is heel vlot verlopen. Waarvoor dank.

The availability of your team to help and guide people to understand their finances better is what really makes Accountable valuable. While the AI is able to give answer to most of the basic questions, specific scenarios need counsel from a human which your team performs beautifully.
