Key Takeaways
Klarna is set to significantly expand its European footprint after signing a framework agreement with Worldline, Europe's largest payment acquirer, that will embed its flexible payment options across 1.2 million merchant locations both online and in-store. The deal deepens the integration of fintech services into traditional payment infrastructure, a move expected to accelerate growth for both companies.
"This is a huge step in our mission to make Klarna flexible payments available to everyone, everywhere," David Sykes, Chief Commercial Officer at Klarna, said. "Partnering with Worldline, Europe’s largest card acquirer, gives us an incredible opportunity to connect even more businesses with our platform and support consumers everywhere to pay smarter."
The partnership will roll out in phases starting in 2026. The initial stage focuses on Worldline’s Global Collect platform for international e-commerce, followed by its GoPay platform for small and medium-sized businesses. In the final phase, Klarna's full suite of BNPL services will be extended to Worldline’s network of in-store point-of-sale (POS) terminals. Critically, Worldline will also act as the transaction acquirer, creating a unified system for merchants.
For Klarna, the deal provides direct access to a massive new merchant base, potentially boosting transaction volumes from its existing 119 million active users. For Worldline, which posted €4 billion in revenue in 2025, it enriches its platform with popular flexible payment options. This serves as a key strategy to attract and retain merchants in an increasingly competitive payments market by giving consumers the convenience they now expect.
The collaboration is structured to bring Klarna’s services, which include immediate payments, interest-free credit, and longer-term financing, to different segments of Worldline's customer base over time. This phased approach ensures a streamlined onboarding process, first for large international travel and digital merchants, and later for a broader network of e-commerce and physical retail stores.
"Worldline is thrilled to partner with Klarna to bring innovative payment solutions to businesses of all sizes," commented Markus Frei, Head of Worldline Acquiring Services. "Leveraging our strong local presence, this collaboration will introduce BNPL services across markets, delivering real value for merchants and consumers alike."
This partnership represents a significant convergence between traditional card acquiring infrastructure and the alternative payment methods championed by fintech firms. By embedding Klarna’s options directly into Worldline’s core technology stack and handling the backend acquiring process, the two companies are removing a major point of friction for businesses. Merchants will no longer need to manage disparate systems, allowing them to offer more payment choices and potentially increase customer satisfaction and sales volumes. The deal positions both firms to capitalize on the growing demand for flexible and digital-first payment solutions across Europe.
