very interesting links, thanks! I was not aware that the technology had progressed that rapidly (outside of Neuralink, which captures a lot of the attention)
That's something else, thats for directly connecting to Peppol, which few business will do (mostly very large businesses, or financial companies).
Most businesses will use a accounting system anyway, and most of those will support Peppol out-of-the-box. So instead (or in addition) to sending an e-mail, the invoice will be sent directly into their accounting system (and their bank, if they choose).
Really, it simplifies things a lot! No more punching/copying of stuff from PDFs into your online bank. The cost is not really high, just a bit annoying (typically some euros a month + a few euros pr invoice).
(I probably could have found a cheaper provider but I don't send many invoices so it is ok).
just in case anyone think this is serious, the literal translation is of course "National bank" (Riks refering to Riket / "Reich" in German, meaning the nation).
