What to know about e-invoicing in Germany

What matters for you as a freelancer

• ✓Agency OS already produces a compliant invoice for this country today — no extra setup needed on your side.
• ✓If your client asks for an e-invoice, you can send one immediately.
• ✓Keep an eye on the mandate date above — it determines when e-invoicing becomes mandatory rather than optional for domestic B2B.

What you don't need to worry about

• –You don't need to change your invoicing workflow ahead of the mandate — Agency OS already outputs the required format.
• –Cross-border invoices to clients in other countries aren't affected by this country's domestic mandate.

What must be on a valid B2B invoice

• ·Full name and address of both supplier and recipient
• ·Supplier's tax number or VAT ID (USt-IdNr.)
• ·Invoice date and a unique, sequential invoice number
• ·Quantity and description of the goods or scope of the service
• ·Date of supply (or the period it covers)
• ·Net amount broken down by tax rate
• ·Applicable VAT rate and VAT amount — or the reason for exemption
