About Maesn

Maesn provides a unified REST API that lets software products connect to ERP and accounting systems, including DATEV, SAP, Sage and Microsoft Dynamics, through one integration.

Its infrastructure is hosted in Germany, and the company states it is ISO 27001 certified and GDPR compliant.

Its customers are software companies that want to offer accounting and ERP integrations to their own customers.
