Sure but you are splitting hairs. If I enter a shop to buy sth and the clerk tells me I have to check back in a couple of weeks to get the proper invoice, I as a customer take my business elsewhere.

It's fine if you're running some sort of IT consultancy or whatever, your first invoice will be running weeks after the fact in any case.

Everyone else can wait a week (or less, if you're persistent in nagging the Finanzamt on the phone), but let's be real: if you're a shop owner, you need weeks of "empty" runway to rent a shop, set up the shop, buy inventory, wait for it to arrive... so in reality the week of waiting time won't matter.

IT consultancies are not the majorities of businesses. Additionally, your tax id does not necessarily take a week. And good luck if you do international (but within EU) buisness - the EU VAT id takes even longer.

Additionally, when did we (germans) start to accept and get so stuborn to defend this process? I mean, the process should be: You go to the "Gewerbeamt", fill out the forms, and get the same day a tax id, a EU VAT id, and a one-time token to create your ELSTER accounts and certificates. Thats what digitalization should be. How does anyone think the current, cumbersome process is the ultimate way and that this is considered business friendly, yet tends to defend or glorifies this process?

I believe that we have to get up to speed in digitalization - but there's far bigger fish to fry there than having to wait for a week for a tax ID. Our politicians are incompetent enough as is, and budgets for process improvements (or, to be fair, a lot of gov processes would benefit from complete overhauls) are just as small.
