Good comment. Actually this is what I'm doing... move the logic to the book keeping side and deal with less income e.g. on Hungary with 27% VAT. Nevertheless why do I have to do all this hassle when somebody who sells e.g. a hardcover (vs. ebook) does not need to do this when selling cross border and they need to start thinking in this direction once they cross over 50 - 100,000 € on one country. Because I'm selling digital goods is much harder on my side.
