Definition of dunning

A dunning notice is a request for the payment of an invoice that has not been paid and is beyond the payment deadline, resulting in the debtor being legally in default.

The German Federal Court of Justice defined the term dunning in a ruling as follows:

“Any clear and specific request by which the creditor unambiguously expresses that he demands the performance owed shall suffice [...] as a dunning notice giving rise to default.” (DE)

What is the difference between dunning and a payment reminder?

As a rule, a dunning notice is preceded by a payment reminder. In a payment reminder, the creditor (i.e., you, who is waiting for your money) kindly points out the missed payment to the debtor (your customer who has defaulted). However, this does not mean that the customer is legally in default.

When should you write a dunning notice?

You write a dunning notice when your customer has defaulted on a payment. That is, if the customer has exceeded the payment term of an open invoice (for this reason, it is crucial that you always note the payment term on your invoices).

Customers can miss a payment for several reasons, and the intention is not always malicious. The invoice may have been lost in the mail, or they could have forgotten to pay. Additionally, Your customer could be unable to pay due to cash flow difficulties. And in some exceptional cases, fraud could be the cause. Regardless of the reason, late payments are a problem for you. The growth of small and medium-sized enterprises (SMEs) is particularly affected by liquidity bottlenecks—and their existence is even threatened in some cases. A 2022 study by ibi on online payment processes (DE) shows the biggest challenges facing businesses are a result of non-payments. Considering these risks, you should definitely write dunning notices when payment terms are exceeded.

Do you have to write a dunning notice?

Short answer–No. You are not legally obliged to send a dunning notice if the payment term was clearly stated on the invoice, the debtor is aware of said due date, and still didn't pay. In this case, you can immediately sue for payment of the purchase price.

In most cases, however, such an action is preceded by a dunning process. After all, an invoice can sometimes be lost in the mail, and there is no malicious intent behind the overdue payment. The dunning process is a shorter, less costly procedure to resolve the problem and receive remittance for your goods or services.

Additionally, you are, in all likelihood, interested in maintaining a good relationship with your customers and potentially acquiring repeat business. For this purpose, it is advisable to initiate a lawsuit only as a last resort if the dunning process has brought no results.

Due dates, dunning fees, and interest

If your customer defaults on a payment and you subsequently send a dunning notice, you also have the right to claim a fee for the dunning notices. How high this may be is not precisely defined by law in Germany. However, it may only cover the costs of the dunning notice itself, i.e., paper, printing, and dispatch. Thus, the fee is usually between one and four euros. So-called general costs, such as personnel or electricity, may not be included in the dunning fee.

You may start to collect dunning fees from the due date or payment date of the invoice.

As a creditor, you can charge interest against the debtor in case of late payment—starting from the first day of delay. The permissible interest rate is set by law and amounts to five percent per annum for companies. Details of the legal basis for interest on arrears can be found under Section 288 of the German Civil Code (DE). 

Structure of the dunning system

The deadlines and number of steps in the dunning process are not specified by law, so a three-stage dunning process has become established among companies. The three stages take the form of a payment reminder, then subsequent warnings. First, a payment reminder is sent, followed by a first and second warning. If the payment reminder and warnings have been ignored and the invoice remains unpaid, the case is usually handed over to a debt collection agency.

You can read the typical three-stage dunning process in detail below:

Payment reminder

If your customer has not paid by the agreed payment deadline, a friendly payment reminder is sent—it is possible they have simply forgotten to pay. Therefore, with the payment reminder, only point out to the debtor that the debt still has to be paid.

If your customer still doesn’t pay after a payment reminder, there are no legal consequences.

First warning

If your customer still does not pay despite receiving a payment reminder, it is time to send the first warning. With this warning, you demand dunning fees from the debtor. Additionally, default interest (discussed previously) starts with this warning.

Second warning

If your customer has also failed to meet the payment deadline of the first warning, a second warning will follow. As this is the second warning, you can reduce the payment term to be shorter than the first, after all, your liquidity plus the well-being of your company depends on it. Otherwise, the second warning is structured the same way as the first one.

Judicial dunning procedure or debt collection

If the debt is still not paid after the second warning, it makes sense to hand the case over to a debt collection agency. Debt collection agencies, or collection agencies, are companies that help creditors receive missed payments.

If the previous reminders and warnings have had no effect, you should initiate a legal dunning process. Theoretically, you can start this earlier, but it is customary to send at least two warnings before the legal dunning process. To initiate a legal dunning process, you must have sent at least one dunning notice with a payment deadline that has not been met or where the initial payment deadline has been exceeded by at least 30 days. You can find the requirements for a legal dunning process in detail here.

Structure of a professional dunning letter

In order for a dunning notice to be legally valid, it must contain certain components–similar to an invoice.

Your dunning notice must contain the following:

  • A clear “warning”

  • Invoice number and total of the original invoice

  • Reason for claim

  • Dunning fees

  • Default interest

  • Payment term

  • Name, address, and company name of the debtor 

  • Name, address, and company name of the creditor

  • Creditor bank details

Alternative: Outsource the dunning process

Of course, whether you want to take care of the dunning process yourself or hand this task over to a third party is your decision. However, outsourcing this process will save time and effort, which you can invest in other areas.
