The Solution

Paywise accelerates growth with Maesn’s Unified API, enabling ERP integrations and streamlined debt collection features.

Paywise turned to Maesn’s unified API for ERP and accounting systems. With Maesn, they were able to offer integrations with all of the tools their customers use, completing the implementation in less than one sprint and at a significantly lower cost than developing in-house.
Maesn’s comprehensive API also enabled Paywise to unlock valuable new features, including:

  • Automatically pulling lists of overdue invoices from various ERP systems.

  • Providing customers with a clear, user-friendly interface to select invoices from an overview.

  • Allowing customers to initiate the debt collection process directly from their dashboard.

The Challenge

Paywise seeks seamless ERP integration solution to accelerate growth in competitive debt management market.

Paywise, a leading provider of debt management solutions, is experiencing rapid growth and is eager to expand further. However, their customers across the DACH region use a variety of accounting and ERP systems, making it difficult to offer a consistent, automated experience. For Paywise to stand out in a competitive market, seamless integrations and real-time data exchange became critical.


After attempting to build an integration with sevDesk in-house, Paywise quickly realized the development process was far more complex and resource-intensive than expected. They needed a faster and more efficient solution to meet their time-to-market goals and support their growth.
