Key Requirements for German Invoices
To ensure your invoice is legally compliant in Germany, it must include several mandatory elements. A German invoice requires the full names and addresses of both the supplier and the recipient. You'll also need to state your tax number (Steuernummer) or VAT identification number (Umsatzsteuer-Identifikationsnummer), depending on the transaction type. Each invoice must have a unique, sequential invoice number, ensuring no gaps in your numbering system. Furthermore, clearly specify the date of issue and the date of supply or service if different from the invoice date. Detail the quantity and type of goods or services provided, the net taxable amount, the applicable VAT rate, the VAT amount, and the total gross amount due.
