Germany

What	Detail
ZUGFeRD	Your full invoices are issued as ZUGFeRD: a PDF that reads like any other and carries the invoice data inside as XML, so your customer's accounting software reads it without typing anything. They're saved in the order's documents, with the XML separately.
Email, phone and IBAN	To invoice they're required, even though they're optional in Tax information. If you already had them, they come filled in for you to confirm. The IBAN is checked as you type it.
Small business (§ 19 UStG)	If you're exempt from VAT, tick the box when activating: your invoices will go out without VAT and with your country's legal statement (Selling without VAT). If your default tax isn't 0%, it warns you.
No USt-IdNr.	If you're a small business without an intra-community VAT number, your invoices still carry the e-invoice: your Steuernummer (tax number) goes in it as the seller's tax number.
Simplified invoice (Kleinbetragsrechnung)	To individuals, up to €250 (VAT included).

What	Detail
“I am not registered for VAT”	Below the VAT threshold a British business has no VAT number. Tick the box and you activate without a tax number; your invoices will go out without VAT and with “Not registered for VAT.”.
Companies (Ltd, LLP)	The invoice has to carry the company's full name exactly as it appears on its certificate of incorporation: enter it as the legal name. The law requires the company number, the place of registration and the registered office on your letters, order forms and website, not on the invoice. If you still want them to appear on it, in Tax information: the number in Company registration number, and the place of registration and the registered office in the Legal footer text.
Business customers	They aren't asked for a VAT number, because many don't have one.

Poland

What	Detail
KSeF	Every invoice to a business is sent to the Polish Ministry of Finance's system (KSeF) and is only valid once KSeF accepts it. We send it for you: the invoice takes its number when you issue it and stays Waiting for KSeF, usually for a few minutes. Its PDF appears as soon as KSeF accepts it, and its ⋮ menu also has KSeF's receipt (UPO).
KSeF token	It's required to activate. Create it in the KSeF Taxpayer Application (Aplikacja Podatnika KSeF) with the permissions “Wystawianie faktur” and “Przeglądanie faktur”, and paste it into the setup wizard. We don't keep it ourselves: our invoicing provider keeps it and only uses it to send your invoices. If it expires or you revoke it, change it with Change token in Settings → Workshop → Invoicing: the invoices that were waiting for it are sent by themselves.
Your numbering	If you already sent invoices to KSeF with another program, don't continue its numbering here: KSeF rejects a number it already has. Start a series of your own (another prefix) for your BolloPrint invoices.
If KSeF rejects an invoice	The invoice tells you why. Fix it where the data lives (the customer record or your tax information) and press Send again: the preview opens and the invoice goes out with a new number. The rejected number is left unused and noted in its history. If in doubt, open a support case.
VAT exempt (art. 113)	If you're exempt from VAT, tick “I am a small business exempt from VAT” when activating: your invoices go out without VAT and with the art. 113 wording, and your NIP is still printed. That way, from BolloPrint you can only invoice Polish businesses and private customers.
Before issuing	Your business customer's NIP is checked. Invoices to Polish businesses over PLN 15,000 (VAT included) can't be issued from BolloPrint yet, and the Sale without VAT text can't be longer than 256 characters.
Language	Your invoices always come out in Polish.
Simplified invoice	There isn't one: all your invoices are full invoices.
Private customers	Their invoices don't go through KSeF. If you take payments in person, your cash register (kasa fiskalna) is separate.
