Custom SAP Development

Tailored SAP solutions for unique business processes. ABAP Cloud, CAP, RAP, S/4HANA extensions, custom Fiori apps, and cloud-native development on BTP. Clean code and modern architectures.

Why custom development?

SAP custom development extends standard capabilities with solutions designed specifically for your unique processes. With ABAP Cloud, CAP, RAP, and Fiori extensions, we create scalable, maintainable applications aligned with SAP best practices.

Key advantages

  • Tailored solutions: Specific developments for unique business processes or verticals
  • ABAP Cloud-ready: Modern, cloud-compliant and upgrade-stable code
  • CAP/RAP frameworks: Rapid app development with SAP full-stack frameworks
  • Clean extensibility: Extend functionality without modifying standard code (side-by-side)
  • Native integration: Direct access to SAP data, logic and events without overhead
  • Reusability: Modular components and reusable services

Important considerations

  • Initial investment: Custom developments require significant investment in analysis and development
  • Ongoing maintenance: Custom code requires support, documentation and evolution
  • Upgrade validation: Testing needed on each SAP upgrade to validate compatibility
  • Expertise dependency: Specialized SAP developers needed long-term
  • Complexity risk: Excessive custom code can hinder evolution and upgrades

Why develop with us?

Complete modern SAP stack

Mastery of ABAP Objects, ABAP Cloud, CAP (Cloud Application Programming), RAP (RESTful ABAP Programming), CDS Views, Fiori Elements, SAPUI5, and full-stack development on SAP BTP.

Clean code and best practices

We follow SAP Clean ABAP guidelines, design patterns, automated testing (ABAP Unit), and code reviews. Readable, maintainable and documented code.

Cloud-ready architectures

Cloud-ready developments: stateless, API-first, side-by-side extensions on BTP, and separation of concerns. Upgrade-stable code using released APIs.

Our development process
