For German invoices, the Legal / Germany (§14 UStG) section has Invoice numbering and Seller legal details.

The invoice has a clean new layout. It shows your store name, the invoice number and date, From and Bill to details, an order summary with the payment method and Payment Status, the items with Qty, Unit price and Amount, and the totals.
Step 4: Create an Invoice for an Order
Open an order. In the Invoice box, click View Invoice (1) to see the PDF. Click Send Invoice to Customer to email it. Sending needs the Email add-on.
The same box has View Packing Slip (2) and View Delivery Note (3). See the Packing Slip and Delivery Note guide.
