Which of my customers or suppliers are already connected to the Peppol network?

In OkiOki, you can see at each contact (customer or supplier) whether they are already connected to the Peppol network or not.

When preparing and sending your invoices, OkiOki will also automatically check whether your customer is already connected to the Peppol network and whether you can send them e-invoices. If this is not the case, OkiOki will allow you to send your invoice via email to your customer. Your invoice will then be sent attached in both UBL/XML and PDF format.
