Services: Integration & Interfaces

APIs, system integration and legacy modernization belong together: with API integration and system integration we connect ERP, CRM and line-of-business systems – via REST, GraphQL, ETL or event-driven architectures. A typical starting point: solving integration chaos without big-bang risk.

We modernize existing estates step by step through legacy modernization: first legacy code analysis surfaces risks and dependencies, then modernizing legacy software or targeted replacement such as VB6 replacement. Read more in legacy modernization strategies.

Estimate costs and ROI with our API development cost calculator, legacy modernization cost calculator or integration ROI calculator. Integrations complement automation & workflows and new UIs from software & platforms; compare approaches in monolith vs microservices – Made in Germany from East Frisia.
