What is a Mahnung? Germany's payment reminder, explained

A Mahnung almost always contains the same pieces: who is asking for money, which invoice or contract it refers to (look for a Rechnungsnummer or Kundennummer), the outstanding amount, a new payment deadline, and often a reminder fee (Mahngebühr) of a few euros on top.

Many companies number their reminders — "1. Mahnung", "2. Mahnung", "letzte Mahnung" (final reminder). The higher the number, the closer the sender is to handing the case to a collection agency or a court procedure. But don't rely on getting three warnings: there is no law that requires a sender to send more than one.

• Mahngebühr — a reminder fee, usually a few euros.
• Verzugszinsen — default interest that can accrue once you're officially late.
• Inkasso — a debt collection agency; once involved, real extra costs appear.
• Mahnbescheid — a court payment order, a separate and much more serious document.
• Widerspruch — an objection; how you push back in writing if you disagree.

Usually one of five boring reasons: you forgot to pay, the original invoice never reached you (very common after moving), a direct debit failed because of insufficient funds or a changed account, your payment and the reminder crossed in the mail, or the sender's records are simply wrong.

None of these make you a bad person, and the first two are the most common. What matters now is sorting out which one it is — because the right response is different for each.

A single Mahnung is a nudge, not a catastrophe. Legally, though, it can put you in Verzug (default), which means the sender may add default interest and further costs from that point on. You can also end up in default without any Mahnung at all — typically 30 days after a due invoice, if the invoice pointed that out.

The real escalation ladder looks like this: reminder → further reminders with fees → a collection agency (Inkasso) or a court payment order (Mahnbescheid). A Mahnbescheid arrives in a yellow envelope from a court, and you have only two weeks to object to it. Each rung adds cost, so the cheapest moment to act is now.

Scam reminders — by post and especially by email — are a real industry. They imitate well-known brands, invent subscriptions you never ordered, and rely on the fear the word Mahnung triggers.

• Do you actually have a contract or order with this sender? If not, that's the biggest red flag.
• Does the letter name a real invoice with a plausible date and amount, or is it vague?
• Is the account (IBAN) in the sender's name and country, or somewhere unexpected?
• When in doubt, contact the company through its official website — never through the phone number or link in the letter itself.

If the claim is invented, you don't have to pay just because a letter looks official. Consumer advice centres (Verbraucherzentrale) publish current warnings about known scam waves.
