Recurring invoices and retainers in Germany

Last reviewed: October 2026

When recurring invoices help

• Monthly retainers (advisory, support, content)
• Hosting / maintenance with a fixed fee
• Subscriptions with a clear service period

Put duration, notice period, and what the fee covers in the quote — or scope will creep.

Rules per period

• Each period = its own invoice with a new sequential number
• State the service period on the invoice (e.g. “March 2026”)
• Keep VAT / Kleinunternehmer wording consistent — document status changes
• For B2B: plan e-invoices when the mandate or the client requires them
• If unpaid: use a reminder / dunning flow

Setup checklist

1. Clean client data and payment terms once.
2. Template / schedule: amount, period, next invoice date.
3. Quick review before send (price change, pause, cancellation).
4. Send + archive (GoBD) each period.

Common mistakes

• Reusing the same PDF number every month
• Missing service period — client does not know what they paid for
• Ignoring cancellation and keeping billing
• Forgetting the Excel row — cash-flow gaps
