The 4 Stages of the Reminder Process
Stage 1: Payment Reminder (Friendly)
When: 3-7 days after due date
A friendly reminder - maybe the invoice was just overlooked.

Stage 2: First Reminder
When: 7-14 days after payment reminder
Now it becomes more formal. You can charge reminder fees from here.

Stage 3: Second Reminder (Final Reminder)
When: 10-14 days after first reminder
Now it should be clear that this is serious.
Subject: 2nd and Final Reminder - Invoice No. 2025-042
Dear [Name],
unfortunately, despite our previous reminders, we have
not yet received payment.
Outstanding amount including fees: €1,215.00
We hereby request you one final time to pay the amount
within 7 days.
If payment is not received on time, we will proceed
without further notice to:
• Engage a debt collection agency OR
• Initiate court proceedings
Any additional costs incurred will be charged to you.
Best regards,
[Your Name]
Stage 4: Debt Collection or Court Proceedings
When: 7+ days after final reminder
Now you have two options:
| Option | Advantages | Disadvantages |
|---|---|---|
| Debt Collection | Less effort for you, pressure on debtor | Costs commission (often 10-20%) |
| Court Order | Cheaper, results in enforceable title | More effort on your part |

Calculating Late Interest
From the start of default, you can charge interest.
Interest Rates (2025)
| Customer | Base Rate + | Effective Rate |
|---|---|---|
| B2B | 9 percentage points | approx. 12.12% p.a. |
| Consumer | 5 percentage points | approx. 8.12% p.a. |
Calculation Formula
Late Interest = Invoice Amount × Interest Rate × Days / 365
Example Calculation
- Invoice Amount: €1,000
- Days in Default: 30
- Interest Rate B2B: 12.12%
€1,000 × 0.1212 × 30 / 365 = €9.96

Reminder Fees: What Is Allowed?
You may charge reasonable reminder costs:
| Reminder | Typical Fee |
|---|---|
| Payment Reminder | €0 (optional) |
| 1st Reminder | €2.50 - €5.00 |
| 2nd Reminder | €5.00 - €7.50 |
| 3rd Reminder | €7.50 - €10.00 |
Note: Fees must reflect actual costs. Courts are stricter with consumers.

Court Payment Order: How It Works
Step 1: File Application
Online via the court portal or by paper form at the responsible court.
Step 2: Pay Costs
| Amount in Dispute | Court Costs |
|---|---|
| up to €500 | €32 |
| up to €1,000 | €32 |
| up to €2,000 | €49 |
| up to €5,000 | €73 |
Step 3: Order Is Served
The court serves the payment order to the debtor.
Step 4: Possible Responses
| Debtor Response | What Happens? |
|---|---|
| Payment | Done |
| No response (2 weeks) | Apply for enforcement order |
| Objection | Regular court proceedings |
Step 5: Enforcement Order
Once final, you have an enforceable title (valid 30 years). The bailiff can then seize assets.

Legal Framework
BGB § 286 - Default of the Debtor
The debtor is in default if they do not perform upon a reminder from the creditor.
BGB § 288 - Interest on Arrears
A monetary debt is to be paid with interest during default at 5 percentage points above the base rate. For legal transactions not involving a consumer, the rate is 9 percentage points above the base rate.
BGB § 280 - Damages for Breach of Duty
If the debtor breaches a duty, the creditor may demand compensation for the resulting damage.

Frequently asked questions
When is a client in payment default?
For business customers (B2B), default occurs automatically 30 days after invoice receipt - even without a reminder. For private individuals, you must first send a reminder. If specific payment terms are on the invoice, default begins the day after that deadline.
How high can reminder fees be?
Reminder fees must be reasonable and reflect actual costs. Typical amounts are €2.50-5 for the first reminder and up to €10 for subsequent reminders. Excessive fees can be deemed invalid by courts.
Do I have to send reminders before court proceedings?
No, legally you can apply for a court order as soon as the debt is due. Practically, it makes sense to send reminders first - clients often pay and you save court costs.
What does a court payment order cost?
Court costs depend on the amount in dispute. For a claim up to €1,000, you pay €32 in court fees. These costs can be recovered from the debtor if they pay.
When is a debt collection agency worthwhile?
Debt collection is worthwhile when you want to avoid the effort or the claim is large enough. Collection agencies typically take 10-20% commission. For small amounts (under €100), the court route is often cheaper.
What happens if the debtor objects to the payment order?
If the debtor objects, the case goes to regular court proceedings. You must then prove your claim in court. This is more effort, but usually successful for legitimate claims.
How long can I pursue a claim?
The standard limitation period is 3 years (from year-end of invoice date). With a legally binding enforcement title (enforcement order or judgment), the period extends to 30 years.
