Limitation at the end of the year
§ 195 BGB (3 Jahre)
Claims are generally time-barred after 3 years, calculated from the end of the year in which they arose (§§ 195, 199 BGB). A payment reminder does NOT suspend limitation — that requires a court payment order (Mahnbescheid), an action or an acknowledgment.
It is an AI, not a person: nobody looks at your individual case, and we do not know who signs up or for what reason. That is why we give pointers, but no legal advice on the individual case. Guidelines and playbooks in the platform are only guardrails: the AI relies on the available sources and your information. AI can make mistakes — check important results, and if in doubt, ask a lawyer.
What we pay special attention to
Curated from real cases. The AI review flags exactly these points in your document.
The 30-day period applies to consumers only if the invoice points this out (§ 286 Abs. 3 S. 1 BGB).
A reminder is NOT a prerequisite for default if the payment date is fixed by the calendar (§ 286 Abs. 2 Nr. 1 BGB).
The base interest rate changes every six months (1 January / 1 July) — incorrect calculations lead to the claim being rejected.
The €40 flat fee applies only in B2B (§ 288 Abs. 5 BGB) — it is credited against legal fees.
Reminder costs are recoverable only to the extent actually incurred (postage, material — no flat "reminder fee of €10").
Part payments must be allocated correctly under §§ 366, 367 BGB (first costs, then interest, then the principal claim).
The claim becomes time-barred after 3 years (§ 195 BGB) — a reminder alone does not suspend limitation.
Standard-term clauses on "flat reminder fees" are often invalid under §§ 307, 309 Nr. 5 BGB.
What you can do here in 5 minutes
Default in payment occurs automatically — 30 days after the invoice for consumers (§ 286 Abs. 3 BGB) or immediately where the time for performance is fixed by the calendar. Default triggers statutory default interest: 5 percentage points above the base rate (§ 288 Abs. 1 BGB) for consumers, 9 percentage points above the base rate + a €40 lump sum (§ 288 Abs. 2, Abs. 5 BGB) in B2B transactions. We do the calculation and you have the payment reminder in 2 minutes.
Enter the invoice details (amount, date, consumer/business) — we calculate default interest to the day against the base rate of the Deutsche Bundesbank applicable at the time, add the €40 lump sum (B2B) and deliver a payment reminder with all consequences of default.
