From 2026, all invoicing between Belgian companies must be done via the Peppol network. As a business customer, it would be convenient to start receiving all your energy invoices as e-invoices now. With Eneco, the process is quite simple. Here’s how to proceed.
To receive electronic invoices as a business customer with Eneco, follow these steps:
E-invoicing is not the same as digital invoicing, such as a PDF or a scanned invoice. An e-invoice is a specific XML file sent in 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 like Accountable to read it.
💡Accountable tip: with Accountable, you can register for free with Peppol to send and receive e-invoices via our app. This service is available to all Belgian self-employed professionals, even in the free version. Try Accountable now.
To receive e-invoices from Eneco or other energy suppliers, you’ll need suitable invoicing or accounting software. Then, you can register for free with Peppol through this software.
Is your supplier not yet up to speed with e-invoicing? Let us know, and we’ll contact them to help move the market forward and save you time.
With Accountable, it’s easy:
It may take a few minutes for your registration to be processed. Not sure if it worked? Check whether your company is listed in the Peppol Directory.

This program is a lifesaver, and it is always improving. Plus, it has an AI chat feature that is actually useful.

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 answers to most basic questions, specific scenarios need counsel from a human which your team performs beautifully.

They always answer for questions wherever is via direct e-mail or through app. If they can’t answer fully they will forward you to the right place. Documents were always prepared well and ready to send further to government. Everything is intuitive in the app and easy to sort out even for someone completely green in this field.
