+You're a commerical customer or just someone who likes to keep their paperwork
+in order? Welcome to uberspace! Please read on to learn how to obtain invoices,
+receipts, and how we handle VAT.
+
+Invoices
+--------
+
+We offer two kinds of documents:
+
+1. **pro forma invoices**: Issued before you make a payment. Can be used to give
+   to your accountant or treasurer for transfer.
+2. **receipts**: Issued after transfer. A document outling how much has been
+   paid by who, to whom, what for, and at what VAT rate. For your books.
+
+Both documents are available on the `Accounting page <dashboardaccount_>`_.
+
+Pro forma invoices
+==================
+
+Please enter the name and address that you want your pro forma invoice to include as a voucher recipient and then select the amount you wish to transfer. Please note that a pro forma invoice is legally only an order confirmation. It does not qualify as an invoice within the meaning of § 14 UStG. However, you will receive a corresponding receipt after receipt of payment, which will then do this.
