Mac App store ignores VAT

Wanting to buy FCPX for my business, but found an issue with the Mac App store. As a pro customer based in Europe/Belgium I can't enter my VAT ID, and Apple doesn't send an invoice with their address and VAT details on it (it's a receipt with this statement on the bottom: This is not a VAT notice).

I've been researching this a bit and stumbled on this story:

It seems like it will take a lot of hassle to get a proper invoice, which is required by law for any business. What's up with that?

You can get iTunes gift-cards from your local dealer then you get the VAT (on dealer sales receipt) and then you pay appstore with them.
