Invoice address
You store the invoice address once in the account settings. It appears on all invoices and receipts PostPal issues for top-ups and shipping. Your VAT number also determines the tax rate: a German VAT ID (DE followed by 9 digits) or an empty field results in 19% VAT; a valid VAT ID from another EU country (e.g. Austria, the Netherlands) triggers the reverse-charge mechanism — PostPal then charges 0% VAT, and you self-assess the tax in your own country. Non-EU customers are still billed 19% German VAT.
The invoice address is the address PostPal uses on all invoices and receipts. You store it once in the account settings and keep it up to date there.
Important to know:
- The invoice address appears on every document for credit top-ups and shipping.
- It is separate from your payment method - you maintain both independently.
- If you change the address, only future documents use the new address.
A correct invoice address ensures your documents are usable for accounting.
VAT number and tax rate:
Your stored VAT number determines which tax rate applies to your balance debits:
- German VAT ID (format
DE+ 9 digits) or no entry → 19% VAT. - Valid VAT ID from another EU country (e.g. Austria
ATU..., NetherlandsNL...B..) → 0% VAT under the reverse-charge mechanism (§13b UStG). The cost estimate and invoice then show "Reverse Charge" wording instead of the VAT line. - Customers outside the EU are still billed 19% German VAT — reverse charge only applies within the EU.
PostPal validates the format of the entered VAT number on save and rejects obviously invalid values.
Frequently asked questions
Where do I enter my invoice address in PostPal?
Maintain the invoice address in the account settings under Invoice address. It is used for all invoices and receipts.
Can I change the invoice address later?
Yes. You can update the invoice address in settings at any time. Future documents use the new address.
Is the invoice address the same as the payment method?
No. The invoice address defines which address documents are issued to; the payment method defines how you pay. You maintain both separately.
Why isn't VAT being charged on my account?
If you've entered a valid VAT ID from an EU country other than Germany (e.g. an Austrian ATU number), the EU reverse-charge mechanism applies: PostPal charges 0% VAT, and you self-assess the tax in your home country (§13b UStG).
What format does my VAT number need to be in?
A German VAT ID is DE followed by 9 digits (e.g. DE123456789). For reverse charge, you need a valid VAT ID from another EU country in that country's official format (e.g. Austria: ATU + 8 digits). PostPal validates the format on save and rejects invalid input.
I don't have a VAT number — what happens then?
Without a stored VAT ID (e.g. as a small business exempt from VAT registration), the default 19% German VAT is charged.
