ECC to S/4HANA Cloud – Licensing Strategy, Contract Structure & Commercial Levers

Migration from SAP Legacy ERP systems to S/4HANA is a commercial and technical upgrade. For some organisations, it’s their first encounter with the new SAP cloud commercial model, introducing subscription-based licensing, improved functionality across business processes and improved processing capabilities. To decide whether your business requires a modern change to S/4HANA requires careful planning and a thorough review of the current IT landscape. The choices made during this transition will define an organisation’s cost base and contractual flexibility for years to come.

The Challenging licensing Landscape

Many businesses operating under SAP’s ERP Central Component (ECC) have become accustomed to the traditional perpetual license model, with annual maintenance fees and the ability to buy software up front. With SAP ECC’s mainstream support ending in 2027, and extended maintenance only available until 2030, the message from SAP is clear; now is the time to decide the future landscape of your company.

SAP’s strategic pivot to the cloud introduces new metrics and new product bundles built on the in-memory HANA database. Two main deployment models exist, in addition to a hybrid (private and public) scenario where both coexist:

S/4HANA Cloud, Public Edition – A multi-tenant SaaS model with standardized processes, continuous updates, and lower total cost of ownership.

S/4HANA Cloud, Private Edition – A single-tenant deployment (typically via RISE with SAP, now referred to as Cloud ERP Private) – allows organizations to retain their existing customizations and configurations during the move to the cloud. However, in line with SAP’s “Clean Core” strategy, organizations are encouraged to gradually reduce in-core custom code and shift extensions to the SAP Business Technology Platform (BTP) for greater agility and maintainability.

With each approach offering its own contractual implications, customers must now navigate between choosing subscription contracts and meeting business needs.

Common Challenges in Migration

Item	Details
1. User Metric Shifts	Named User types under S/4HANA differ from those in ECC by introducing new roles and capabilities. Misaligned classifications can dramatically increase licensing requirements due to fundamental changes in how usage is measured and licensed. A pre-migration audit and user mapping exercise helps ensure the right users are matched to the right license types and prevents unnecessary spend.
2. Contractual Lock-In and Future Flexibility	SAP’s move toward subscription models means organisations must commit to multi-year contracts, usually 3-5 years, with defined user volumes and service levels. Negotiating flexibility clauses, such as rights to adjust user counts, swap entitlements or transition between deployment models is critical to prevent being locked into a commercial structure that may not fit business needs in future.
3. Change Management	Moving to S/4HANA Cloud requires a shift not only in processes and user experience but also in how management oversees operations and costs. With the introduction of consumption-based services such as the SAP Business Technology Platform (BTP), usage can quickly drive-up expenses if not actively monitored. As a result of this, training both end users and leadership teams ensures employees can navigate new cloud processes while managers establish proper cost controls to ensure a smooth transition internally.
4. Downtime Lag	For a project as large as transitioning an entire ERP landscape, timing is crucial. System downtimes during data migration or cutover can cause significant disruptions to day-to-day operations, from transactional backlogs, data inconsistencies and interrupted business processes. To mitigate risk, building a strategy around business activities is a necessity to remove any disruptions during the migration process.

Strategic Levers for Better Commercial Outcomes

A successful S/4HANA migration strategy begins with clarity. That means mapping current entitlements, future requirements and understanding how SAP determines license usage and value. The most effective organisations use this insight to shape their negotiation strategy early, not after contracts are presented. These include:

Item	Details
1. License Conversion Credits	SAP often offers credits for existing ECC licenses when you move to S/4HANA. By identifying and removing inactive or underused entitlements before discussions you can strengthen your position and reduce the cost for S/4HANA licenses. Customers can expect to get 60% with these credits depending on factors such as license utilisation, contract maturity, and transition path. With the trend of diminishing credit rates year-on-year, customers should plan their transitions for this accordingly.
2. S/4HANA User Mapping	As we mentioned before, moving your systems to S/4HANA requires a new user licensing model. SAP’s Full Use Equivalent (FUE) pricing can vary depending on deal size, user allocation, and contractual terms. Presenting SAP with a well-documented view of your actual user consumption allows you to challenge default FUE assumptions, negotiate tier-based discounts, and avoid over-allocation of premium user licenses.
3. Negotiate offers	It is imperative to remember that SAP’s first offer is not the final offer – it’s negotiable and often not the best deal you can achieve. By going into discussions equipped with data-driven insights on usage, entitlements, and market benchmarks you can strengthen your negotiating position.
4. Dual-Use Rights	The transition to S/4HANA from ECC is an arduous and long process. By negotiating dual-use rights in your migration process will allow you to operate SAP ECC and S/4HANA in parallel without paying for both systems, until you are fully transitioned to the cloud.

At JNC

At JNC, we approach SAP S/4HANA migration as both a technical evolution and a commercial reengineering exercise. Our work goes beyond compliance; we focus on designing and negotiating the commercial framework that will govern an organisation’s SAP estate for the next decade.

We bring together licensing expertise, commercial negotiation experience, and deep understanding of SAP’s evolving commercial structures. That means identifying where overlapping costs can be eliminated, ensuring contractual clauses protect clients during transition and optimising user classifications to align with real operational usage. What distinguishes JNC is our ability to combine commercial acumen with SAP technical insight. We understand the fine print of contracts and the underlying systems that drive them. This dual perspective allows us to anticipate where SAP’s models create risk and where they create opportunity.

For organisations planning their migration to S/4HANA, our role is to ensure the transition is not only technically successful but commercially intelligent, safeguarding budgets, preserving flexibility and creating a licensing foundation that supports growth, not restricts it.
