Kyktir UBL Viewer

With e-invoicing becoming mandatory in Europe, more and more UBL files are being exchanged via the Peppol-network.
These are XML files that are difficult to read by default.

Kyktir has an UBL Viewer embedded, which allows you to open the received UBL documents.

You can see the XML content, the PDF preview (if available) and a general overview.
