About BilliePay

In search of an efficient and scalable solution, Contorion turned to the Berlin-based start-up Billie. Together with the payment and factoring specialist, the B2B retailer was able to introduce a data-based, automated BNPL solution. Today, the online store offers stable limits up to 100,000 euros, even for new customers and guests, as well as flexible payment terms of up to 120 days. Due to high acceptance rates of more than 85 percent and the improved user experience, the conversion rate has increased by more than 50 percent. Together with Klarna, Billie has been offering BNPL to business customers as a plug-and-play solution for a few months. "B2B buyers today are digital-first and used to the automated processes from B2C," says co-founder Dr. Matthias Knech
