SAP ECC end of mainstream maintenance in 2027 creates pressure. S/4HANA licensing is fundamentally different—and often far more expensive than enterprise buyers realise. We conduct forensic analysis, model true migration costs, and defend your interests in contract negotiations before commitment.
SAP engineered a discontinuity. In 2027, mainstream support for SAP ECC—the foundation of the majority of enterprise SAP deployments globally—ends. For many organisations, that date triggers panic buying. And SAP knows it.
S/4HANA licensing is fundamentally different from ECC. The shift from on-premise perpetual licensing to cloud-forward models, the replacement of older licensing metrics with Named Users and Full Use Equivalents (FUE), and the commercial incentive structures built into RISE with SAP contracts mean that cost models don't carry over. Organisations who migrate without forensic analysis routinely discover—mid-contract—that they're paying 40–60% more for licensing alone.
The danger is greater because SAP structures S/4HANA offerings across three distinct deployment models, each with different licensing economics: S/4HANA Cloud Public Edition (subscription-only, lowest transparency on true cost of ownership), S/4HANA Cloud Private Edition (fixed cost, but requires RISE with SAP commitment), and S/4HANA on-premise (perpetual with extended support, but higher initial cost). Most organisations negotiate without understanding which model minimises their true total cost of ownership—and SAP's sales teams have no incentive to guide them toward the cheaper option.
We defend against that by conducting independent, forensic analysis of your current SAP estate, mapping your licensing footprint to each deployment model, stress-testing negotiation scenarios, and identifying the economic trade-offs before any commitment is made. Our team includes former SAP insiders. We know how SAP structures these deals. And we push back.
SAP controls the narrative around S/4HANA licensing. We control the forensics. A single advisory engagement routinely saves enterprise buyers millions in licensing costs and operational complexity.
Book a Free ConsultationS/4HANA Cloud Public Edition is a subscription model—you pay per month or year, pricing scales with Named Users, and you share infrastructure with other organisations. S/4HANA Cloud Private Edition is part of RISE with SAP: you commit to a multi-year contract, pricing is fixed, and you get dedicated infrastructure. Public is cheaper entry; Private locks you in but offers cost predictability. We analyse both against your actual usage and cost structure to show which minimises total cost of ownership.
In S/4HANA, a Named User is someone with active system access—typically counted monthly based on peak active users. In ECC, you may have licensed by role (FI/CO users, MM users, etc.) or device. The mapping between ECC roles and S/4HANA Named Users is not 1:1. SAP often interprets the conversion conservatively—meaning you'll need more Named User licenses than your head count suggests. We conduct detailed gap analysis: we pull your actual ECC licensing profile, model how your business processes map to S/4HANA user types, and show exactly how many Named Users you actually need.
Full Use Equivalent (FUE) is SAP's metric for measuring the "size" of a Named User's access. A full FUE grants access to all SAP systems; partial FUEs grant restricted access. In theory, restricted users cost less. In practice, SAP's rules for what constitutes a partial FUE are vague, and SAP's audit positions routinely push organisations toward full FUEs. We conduct forensic classification of your user base: we review actual access rights, identify opportunities to legally downgrade users to partial FUEs, and build a defensible classification that withstands SAP audit challenge.
Typical increases range from 35–60% for licensing alone—varying by industry, system scope, and deployment model. A pharma company with heavy regulatory user access might see 50%+ increases. A retail chain with concentrated MM/WM usage might see 25–35%. Cloud models (Public Edition) tend to be cheaper per Named User; RISE with SAP Private Edition locks in cost but requires multi-year commitment. We build a cost model specific to your estate, stress-test against different user growth scenarios, and show you exactly what each model costs over a 5-year horizon.
SAP's mainstream support for ECC ends in 2027. After that date, you can move to Extended Support (higher cost, lower feature innovation) or migrate. Extended Support pricing is often 40–50% of perpetual licensing cost annually—which, over 5+ years, compounds. For some organisations, Extended Support is the economically rational choice. We help you model the Extended Support pathway vs. migration, including the timing and cost inflection points where one strategy becomes more expensive than the other.
