SAP development and extensions with clean core: ABAP/RAP, Fiori/UI5 and BTP
We build on top of SAP without touching the standard: clean extensions with RAP, CDS and BTP, and Fiori/UI5 apps people actually use. Documented code, 100% yours, that survives upgrades instead of breaking with every support package.
SAP development is building what the standard does not cover — without turning it into technical debt.
Instead of modifying the core (Z objects embedded inside it that break upgrades), we extend with clean core: business logic in RAP and ABAP OO, data models in CDS Views, interfaces via OData and side-by-side extensions on SAP BTP. For the experience layer, Fiori/UI5 apps (Fiori Elements or freestyle) that replace classic transactions nobody wants to use.
The code and configuration are 100% yours from day one.
Six operational reasons, zero adjectives
The code is yours from day one
Repos in your name, documented CI/CD and zero vendor lock-in. If you leave tomorrow, you take it all, running.
WhatsApp API with an official provider
We are a Meta Tech Provider: your WhatsApp Business API line with no middlemen, and chatbots wired to your ERP.
Sprint delivery, CMMI 2 processes
A working demo every two weeks and measurable progress. No "it’s 80% done" without something you can click.
AI applied to your operation
LLM agents, RAG over your data and process automation — the same practice we use to run iTech itself.
Real nearshore: Texas + Monterrey
Legal entity in the U.S. (iTech Corp, Texas), contracts under U.S. law, same CST time zone and USMCA.
ERP with CFDI 4.0 invoicing
We implement Odoo with integrated SAT stamping (PAC), client portal and reconciliation — a full operation, not just software.
When you need it
What it includes
ABAP / ABAP OO development
Business logic with clean code, object-oriented patterns and unit testing, respecting naming conventions and the DEV → QAS → PRD transport system.
RAP and clean core extensions
We extend without touching the standard via RAP, enhancement spots, BAdIs and exits, so your code survives support packages and upgrades.
Fiori / UI5 apps
Responsive applications with Fiori Elements or freestyle that replace classic transactions and improve the real user experience.
CDS Views and OData services
High-performance data models and views on HANA, exposed via OData for reporting, integrations and consumption from Fiori or external systems.
Side-by-side extensions on BTP
Cloud-native development on SAP BTP (CAP) to move custom logic out of the core and keep your path to S/4HANA clean.
Custom code migration and remediation
Analysis of your Z objects with Custom Code Migration (where it applies): we identify obsolescence, dead code and upgrade risks, and migrate or rewrite toward clean core with a prioritized plan.
CI/CD for ABAP and transport governance
A quality pipeline for SAP development: ATC (ABAP Test Cockpit), abapGit where it applies, code review and disciplined management of the DEV → QAS → PRD transport chain.
QA and documented handoff with ARIA
Unit testing, regression testing and code review backed by our internal ARIA platform, with technical documentation and code that is 100% yours.
How we work
1Landscape analysis
We review your SAP landscape and existing custom code (with Custom Code Migration where it applies) and define the target architecture: what stays in the core, what moves to BTP.
2Technical design
Detailed technical specification with the core vs. side-by-side decision, OData contracts and a testing plan, validated with your functional team before coding.
3Iterative development
Coding in DEV with transport management, cross code review, unit testing and functional validation per sprint, with demos so you see real progress.
4Transport and go-live
QAS → PRD transport with a cutover plan, regression testing, technical documentation and post-deploy support.
5Hand-off and evolutionDeliverabledocumentation package, runbook and code that is 100% yours
Knowledge transfer to your internal team, living technical documentation and a prioritized improvement backlog, with the option to evolve the development under AMS support.

The tools and platforms we build it with — chosen for your problem, not for hype.

Contact us →What is clean core and why does it matter?
Clean core means not modifying the SAP standard. Instead of embedding Z objects inside the core, we extend with RAP, enhancement spots, BAdIs and side-by-side extensions on BTP. The benefit? Your code does not conflict with every support package or upgrade, and your path to S/4HANA stays clean. It is the difference between a system that evolves and one frozen out of fear of breaking it.
Can you audit and migrate our existing custom code?
Yes. We analyze your Z code (using tools such as SAP Custom Code Migration where it applies) to identify obsolescence, dead code and upgrade risks, and we deliver a prioritized remediation plan. From there we migrate or rewrite what is needed toward clean core, without touching what already works well.
Do you develop on S/4HANA and on ECC?
Yes. On S/4HANA we use RAP, CDS Views and the native extensibility model. On ECC we develop with future migration in mind, applying clean core so that code does not become an obstacle when you migrate. We define the concrete approach based on your version and landscape.
Do you also do full functional SAP implementation?
No. We focus exclusively on SAP development and extensions: ABAP/RAP, Fiori/UI5, CDS and BTP. We do not do full functional module implementations or licensing — we are a partner within the SAP ecosystem and work alongside your team or your functional consultancy on the technical and development layer.
Does the client own the code?
Yes, 100%. Every development is delivered documented, with unit testing and post-deploy support, and the code, objects and transports are yours. No vendor lock-in: it lives inside your SAP landscape, maintainable by any competent team.
