Our team has delivered enterprise ERP projects across manufacturing, chemicals, food & beverage, and telecommunications.
We work as embedded experts within your team, covering the full ERP lifecycle: greenfield SAP S/4HANA Public Cloud deployments, migrations from SAP ECC or Business ByDesign, Clean Core extensions on SAP BTP, and long-term system optimization.
Where most SAP partners provide consulting and hand off the risk, Novarto’s engineers stay in the code until the system is stable and delivering measurable business outcomes.
Beyond new implementations, we offer comprehensive support and enhancement services for your existing SAP ECC and SAP S/4HANA environments. Our experienced team provides deep technical expertise in developing custom extensions and integrations tailored precisely to your unique SAP ERP landscape.
Our services include:
SAP S/4HANA Cloud is SAP’s next-generation ERP platform, built on the HANA in-memory database and designed to replace legacy SAP ECC systems. An SAP S/4HANA Cloud implementation is the end-to-end process of deploying this system across your organization — covering business process redesign, system configuration, data migration, third-party integrations, user enablement, and go-live support.
There are two primary deployment models. SAP S/4HANA Public Cloud is a standardized, multi-tenant SaaS deployment that follows SAP best practices out of the box — lower cost, faster to implement, and easier to maintain. SAP S/4HANA Private Cloud offers greater flexibility for organizations with complex processes that cannot map directly to the standard model.
At Novarto, we implement SAP S/4HANA Cloud as embedded engineers within your project team — not as external advisors who hand off risk at go-live. Our certified SAP engineers remain accountable for system stability through cutover and beyond.
A greenfield SAP S/4HANA migration means building a completely new system from scratch, without carrying over the configuration or technical debt of your existing SAP environment. Business processes are redesigned according to SAP best practices, and only clean, validated data is migrated. This approach results in a leaner, more maintainable system — but requires significant organizational change management, as existing workflows may change substantially.
A brownfield migration, also called a system conversion, transfers your existing SAP ECC environment directly to the S/4HANA platform, preserving most of your current configuration, customizations, and historical data. This approach is faster and less disruptive to day-to-day operations, but it carries the risk of migrating legacy technical debt into the new system.
The right approach depends on the state of your current SAP landscape, your tolerance for business disruption during migration, and your long-term system maintenance goals. Organizations with heavily customized, aging SAP ECC environments frequently benefit from a greenfield approach despite the higher upfront investment, because it eliminates compounding maintenance costs over time. Novartos’ project architects assess both paths with clients before recommending a migration strategy.
Clean Core is SAP’s architectural principle for S/4HANA that keeps the core ERP system unmodified — running only standard SAP code — while all business-specific customizations and extensions are built externally on SAP Business Technology Platform (BTP). The goal is to ensure that your core SAP system can be upgraded cleanly, without custom code breaking every time SAP releases a new version.
In practice, Clean Core extensions are built using SAP BTP services — including the Cloud Application Programming Model (CAP), SAP Integration Suite, and SAP Build — and connect to the core system through stable, published APIs. This means your custom logic lives outside the core, is independently maintainable, and does not interfere with SAP’s upgrade cycle.
For organizations that previously relied on heavy ABAP customizations in SAP ECC, the shift to Clean Core on BTP is one of the most significant architectural changes in an S/4HANA migration. Novarto specializes in building Clean Core extensions on SAP BTP, helping organizations extend their SAP functionality without compromising system integrity or creating future upgrade risk.
