Client
Since its inception in 2011, our client has fundamentally transformed how companies view invoicing. With an innovative, cloud-based platform, our client product manages the entire invoice-to-cash process. It turns invoicing into an interactive, data-driven, and customer-focused experience.
Their platform optimizes operational efficiency and increases customer lifetime value for businesses with recurring revenue. By replacing traditional PDF and paper invoices with an automated solution, this reduces manual steps, lowers churn, and enhances the customer experience.
Serving clients across Europe, our client combines efficiency, user-friendliness, and smart technology to help large and midsize businesses build stronger customer relationships, reduce customer service cases, and gain a competitive edge in a rapidly evolving market.
Headquartered in Sweden, the company currently employs over 120 professionals
