In a world where digital processes are increasingly becoming the norm, scalable and intelligent finance solutions are essential. This is exactly where KLEVERBILL comes in: a powerful, cloud-based enterprise software platform that automates, structures, and sustainably improves receivables management, dunning, credit management, and the entire accounts receivable function.

With more than 25 years of experience in receivables management and a team of lawyers, legal clerks, and specialists, KLEVERBILL provides more than software—it delivers a complete back-office concept for your company. In this article, we cover all relevant topics that make KLEVERBILL a leading solution for modern businesses.

What is dunning?

Through dunning, you as a business owner collect overdue payments from customers who owe you money. Dunning typically starts with a friendly payment reminder and progresses through multiple escalation stages, up to legal action or the engagement of a debt collection service provider such as KLEVERBILL.

The objective of dunning is to recover outstanding receivables quickly and, wherever possible, without legal disputes—professionally, legally compliant, and customer-friendly.

Drafting reminder letters in English and other languages

In a globalized economy, working with international customers is no longer the exception for companies. But what does a professional reminder letter in English or other languages look like? And what should you pay attention to?

Why multilingual reminders matter

Many companies serve international customers—whether through e-commerce, service contracts, or project work. A reminder in the customer’s native language appears more trustworthy, clearer, and avoids misunderstandings. Studies show: Multilingual reminder letters are processed faster and achieve higher success rates.

KLEVERBILL automatically identifies each customer’s stored reminder language and can generate reminders individually for every language. This saves time, increases professionalism, and improves customer satisfaction—even in challenging situations.
