You mean the government that’s already the tax authority for which you create and report invoices? I can promise you it’s a good thing. Electronic invoices are a lot easier for us (obviously since it’s just a click instead of a whole PDF operation). It also removes a whole bunch of possibilities for mistakes.

The article is wrong about that though, all technical docs are available via the europa portal and reference implementation examples.
