Just the Invoicing is all that is needed, I've tested sending and receiving.

To receive an invoice in the Vendors - Bills screen there is a option "Fetch e-Invoices", when that is clicked the invoice comes almost instantly after it's been sent.

The only issue I have is that this option is not visible in all Bills screens, if I go via the menu to Vendors - Bills the option is not there, if I go via the Dashboard to Purchases (which I think it's the same screen) I do get the option to fetch e-Invoices

I've not had any "unknown" invoices appear, only invoices from a company that wanted to test this functionality so I'm not sure if after some time those invoices are fetched automatically, if anyone knows it would be interesting to know the interfals.

Hello,

As treasurer of a small non-profit, I have already prepared quite a lot for the use of Peppol with the invoicing module.

As a test, I have already created an invoice for a customer, and they confirmed its receipt.

What I am wondering, however, is how I will be notified of a new supplier invoice. Does it automatically appear in the invoicing module?

Kind regards,

Geert

Hi,

To comply with Belgium's mandatory e-invoicing regulations starting January 1, 2026, for B2B transactions, you can use Odoo's Invoicing module. This module includes a built-in, free Peppol access point that supports the necessary formats, such as Peppol BIS Billing 3.0, ensuring compliance with Belgian and European e-invoicing standards.

Hope it helps

Fast and accurate, Thank you Ray !

Just the Invoicing App is fine.
