What is Peppol again, and what role do so-called access points play? Let us briefly explain.
Simply put, Peppol consists of three parts:
A network of Access Points that communicate with each other according to strict rules.
A set of technical standards for documents, security and communication protocols.
An address registry, so that each Access Point knows which company is associated with which Access Point.
And what exactly are these Access Points?
They are your gateway to the Peppol network.
E-invoicing is only possible via an Access Point.
They take care of sending and receiving e-invoices.
Moreover, they guarantee compliance with legislation, correct routing and clear reporting.
Now, what is really important is shown in the diagram below. This illustrates step by step what happens behind the scenes with e-invoicing from ionBIZ:
From ionBIZ, the e-invoice is sent to Maventa - this is the Access Point that ionBIZ uses.
Maventa consults the Peppol registry to find out which Access Point your customer uses to receive invoices.
Once this Access Point is found, Maventa sends the e-invoice there.
The receiving Access Point then delivers the invoice directly into your customer's accounting software.
It starts with a request from your side: we ask you, as soon as you are ready to e-invoice, to log a ticket on the customer portal. From then on, we start the Peppol onboarding flow for your company.
We first perform some checks on your company addresses in ionBIZ (Settings -> General -> Company addresses). This is because certain fields are required for Peppol onboarding. If anything is missing, we will let you know via the customer portal.
If everything looks good on the company addresses, we will trigger the Peppol onboarding. For this, we have developed a new feature that automatically forwards your company addresses to the Maventa Access Point portal. There follows an additional verification step.
You no longer have to do anything yourself. As soon as the onboarding is complete, we will notify you via the customer portal.
You will notice that a new "Send Invoice by" option has appeared on invoices, namely Peppol:
When this option is selected on an invoice, a new "Send by Peppol" button will also appear in the upper right corner:
If you use this button, this individual invoice will be sent via Peppol to the customer - it's really that easy.
Should you send invoices in bulk via the "Send Invoices" button in the invoice view, the State column will allow you to track which invoices have already been processed via Peppol:
After sending the e-invoice, it will automatically be given the In Process status. While your invoice has this status, behind it the invoice will be forwarded to Maventa, and they will check which Access Point your customer is using. Once found, the invoice will go through the receiving Access Point, directly into the customer's accounting system. Afterwards, the invoice will go to sent status in ionBIZ.
Should anything go wrong in this process, the invoice will be in Error status. On the "Extra" tab of the invoice you will find the error message.
What, however, if you are already fully connected to the Peppol registry and sending your invoices via e-invoicing, but one of your customers has not yet completed its onboarding?
We expect that this will occur regularly in the coming months (before the mandatory transition to e-invoicing on 01/01/2026).
In that case, the so-called failover procedure comes into effect. The customer will then automatically receive an e-mail from Maventa with the invoice as a PDF attached. Below is an example of such an e-mail. You can adjust the text section "Message from the sender" as you wish.
With the mandatory introduction of Peppol e-invoicing from January 1, 2026, a big change is just around the corner. Thanks to the integration with Maventa, ionBIZ is fully prepared for this and you can start with electronic invoicing today without any problems. The process runs smoothly, safely and in compliance with legislation, while the failover procedure ensures that even customers who are not yet fully connected will continue to receive your invoices. This ensures that your invoices always arrive correctly and on time.
In short: with e-invoicing via ionBIZ, you are ready for the future.
