Electronic invoicing, without changing your habits

By Nicolas Lemielle, Director of DigiWall · 30 novembre 2025

Electronic invoicing is no longer optional in Belgium. So the question is not whether to get to it, but how much time your teams will lose on it. In Wallify the answer is: one click, the same one they were already making to send a PDF.

Your eligible customers, spotted without you looking

Not all your customers are on the Peppol network yet. Wallify knows it for you: every party carries an eligibility status, and its Peppol identifier is fetched automatically when the record is saved, for the VAT regimes concerned. There is no directory to consult and no number to copy out.

A customer who is not eligible is invoiced as before. You are not running two processes side by side: it is the same screen, the same action, and Wallify picks the right channel.

Invoice, credit note, and batch sending

From an invoice or a credit note, Wallify produces the structured file the network expects and sends it through your Peppol access provider. The file stays attached to the document and can be opened at any time — it is not a black box.

Two separate columns track the fate of each item, and that distinction matters more than it looks: one says where the sending stands, the other the state of the document itself. A document generated but not sent, a confirmed send, a failed send: you see which of the two failed, and therefore where to step in. And from the invoice list, sending happens in one go for a whole selection.

A standard, not a dependency

Wallify produces UBL, the European standardised format. That is a technical detail with a very concrete consequence: your electronic invoicing does not depend on one particular provider. We work today with Falco as our access provider to the network; integrating another would be straightforward, since the format produced would stay the same.

It is also what protects you if your obligations change. A standardised format follows the standard.
