S4Dunning was founded in 2013 (originally as S4Financials), with the aim of developing a flexible debtor management tool that is quick to deploy, easy to use and offers a clear return on investment. The software has since enjoyed rapid growth in its core European markets. As part of Collenda, S4Dunning will continue to serve its loyal customers while expanding its ability to reach and serve new markets. Working closely with the Collenda team in Utrecht, Marcel Blanken and Jeroen Jansen, founders of S4Dunning, will continue to drive the business and cultivate its trackrecord of customer satisfaction.

S4Dunning offers best-in-class solutions for accounts receivable management in mid-sized companies. With automated customer communications and streamlined collections, the tools will be a natural addition to Collenda’s market leading credit and collections management software suite, fitting seamlessly with Collenda’s flagship products, Open Credit 4.0 and Credit Navigator.

"Collenda is investing in the corporate collections sector where we see significant growth in both B2C and B2B segments,” said Hartmut Wagner, CEO of Collenda. “S4Dunning is a fantastic product that inspires a growing and loyal customer base, and is therefore the perfect addition to our product portfolio. Our products’ complementary capabilities and unified roadmap will cement our existing market leadership and ensure we can address our customers’ evolving needs. As part of Collenda, we will introduce S4Dunning to a wider international market to accelerate our growth story."

"The acquisition by Collenda is an important step for us,” said Marcel Blanken, founder and CEO of S4Dunning. “Our goal has always been strong growth driven by great products. As part of a larger company, we can provide even better user support, continuity and further development to ensure satisfaction of our existing and future customers. Collenda’s international sales and marketing capacities will drive further growth for S4Dunning, and we are excited about this next step in our journey."
