Middleware for ERP, CRM and business applications

GSWE connects ERP, CRM and business applications through custom middleware. We structure data flows, decouple systems and make transfer errors visible and manageable within your processes.

Build ERP CRM middleware

An interface becomes reliable when its target state is known after a transfer. GSWE develops field mapping, authentication and manageable failure paths. REST, SOAP or GraphQL follows the interfaces actually available in your systems.
