What is Payment reminder (Mahnung)?
A Mahnung is a formal demand for payment on an overdue invoice — stronger than a polite reminder. It documents delay and often precedes further collection steps.
Many freelancers start with a friendly reminder, then issue a clearer Mahnung with a deadline. Exact legal effects depend on the case — general orientation only, not legal advice.
Practice tips
- Reference the original invoice and due date
- Set a clear payment deadline and keep copies
- Only claim late interest if you are legally entitled
General information only — not legal or tax advice. Tax and e-invoice rules can change; the applicable laws control (e.g. § 19 UStG, § 14 UStG). Confirm with a tax advisor or lawyer if unsure.
