The RISE conversion proposition appears straightforward on first reading. The buyer surrenders the existing on-premise contract, the perpetual licences, and the maintenance stream, and receives in return a multi-year subscription that bundles software, infrastructure, technical operations, and a quantum of innovation credit. The economics that determine whether the conversion is favourable to the buyer depend on the relative weighting of those four components, on the FUE conversion ratio applied to the existing user population, and on three negotiation levers most buyers do not engage until after signature. This article sets out the cost framework, the comparison that matters, and the levers that change the net economics. The full conversion modelling methodology is in our S/4HANA migration compliance service.
The four RISE cost components
The RISE subscription is a bundle. Treating it as a single price obscures the levers. Decomposing it into the four components is the starting position for any conversion model.
Component one — software subscription
The software component prices the S/4HANA Cloud subscription in FUE quantity multiplied by a per-FUE rate. The FUE quantity is derived from the existing named-user position via a conversion table that SAP holds and that is contractually negotiable. The per-FUE rate is the headline price most buyers focus on. Both the quantity and the rate are negotiation levers.
Component two — infrastructure
The infrastructure component covers the hyperscaler hosting, the operating system, the database, and the technical operations. SAP procures the underlying infrastructure from a hyperscaler partner and resells it inside the RISE bundle. The bundled price is rarely the lowest available infrastructure price for the same workload purchased directly, and the bundled service level is rarely the highest. Both gaps are sources of conversion economics that move against the buyer if unanalysed.
Component three — technical operations
The technical operations component covers the system administration activities that the buyer’s own basis team performs in the on-premise model. The component is genuinely transferred to SAP in the RISE model and represents real cost relief for the buyer’s operational team. The relief is rarely the full salary cost of the displaced basis team, however, because the buyer retains responsibility for the application-layer activities that the operations team performed alongside the basis activities.
Component four — innovation credits
The innovation credit component is a quantum of BTP and discretionary-use credit included in the bundle. The credit is denominated in financial value but is consumable only against the SAP BTP catalogue. The credit is frequently sold as a benefit but typically expires unused at the end of the contract year and represents a soft component of the bundle rather than a hard cost offset.
The comparison that matters
The comparison that matters is the all-in five-year cost of the RISE bundle against the all-in five-year cost of the brownfield retention. The brownfield retention cost includes the maintenance stream on the existing perpetual licences, the planned hyperscaler migration cost if the on-premise estate is moving off legacy infrastructure regardless, the basis-team operations cost, and the planned licence growth across the comparison period.
The single error in most conversion business cases is the omission of the planned hyperscaler migration cost from the brownfield baseline. The brownfield estate is typically already migrating to hyperscaler infrastructure independently of any RISE decision. Charging the full infrastructure cost against the RISE side and zero against the brownfield side overstates the RISE conversion economics by a factor that frequently determines the apparent business case. Correcting the baseline produces a more accurate comparison and frequently reverses the recommendation.
The conversion business case is a model. Models are sensitive to their assumptions. The three assumptions that most affect the outcome are the FUE conversion ratio, the brownfield infrastructure baseline, and the BTP credit utilisation. Pressure-test the model on each.
The three negotiation levers
The conversion economics are negotiable on three principal levers. Each is worth between four and eleven per cent of the bundle in our practice.
Lever one — the FUE conversion ratio
The FUE conversion ratio determines how many FUEs are required to cover the existing user population. The default ratio in SAP’s opening proposal is the conservative ratio that maximises the FUE quantity and the resulting subscription cost. The ratio is renegotiable downward on the basis of the reclassification work documented in the override register. A reclassification programme executed before the conversion negotiation moves the negotiated ratio in the buyer’s favour. The brownfield licensing risks article covers the upstream reclassification work.
Lever two — the infrastructure carve-out
The infrastructure component can be carved out of the RISE bundle and procured directly from the hyperscaler under a parallel contract. The carve-out preserves the SAP application subscription and the technical-operations component but separates the hyperscaler cost into a directly procured contract that typically delivers a meaningful saving. The carve-out is contractually possible and is negotiable, though it is rarely volunteered by SAP. See the RISE contracts pillar for the contractual mechanics.
Lever three — the credit roll-over
The BTP credit component is typically structured as a use-it-or-lose-it annual allocation. A roll-over clause that converts unused credit into the following year’s allocation reduces the practical wastage rate of the credit component and increases the realised value of the bundle. The clause is contractually negotiable but is rarely volunteered.
What RISE migrated looks like at year three
The year-three position is the relevant test of the conversion economics. The year-one position is shaped by transition cost and is not representative of the steady-state. The year-three position reflects the realised infrastructure cost, the realised BTP credit utilisation, the realised reclassification of the user population, and the realised growth in the FUE quantity. Year-three RISE costs above the original business-case projection are common, frequently driven by under-anticipated user growth and over-estimated BTP credit utilisation. See the financial services RISE conversion case file for a representative three-year trajectory.
The exit economics
The conversion economics include the exit economics. The RISE contract is a multi-year subscription with a finite term, and the contractual position at the end of the term shapes the negotiating leverage in the renewal cycle. The exit position is rarely modelled in the conversion business case but is a material component of the overall economics. A contract with a clean exit path preserves the buyer’s negotiating leverage. A contract with a sticky exit path produces a renewal cycle in which the buyer is structurally disadvantaged. The RISE contract decoder sets out the exit-clause patterns and their economic consequences.
The independent business case
The single most consequential discipline in the conversion decision is the construction of an independent business case that is not derived from SAP’s template. SAP’s template is constructed to favour the conversion. An independent business case applies the four-component decomposition, the corrected brownfield baseline, and the three-lever negotiation assumption. The independent case typically produces a conversion economics outcome that is between fifteen and thirty per cent less favourable to the conversion than SAP’s template. The gap is the negotiation room. See the RISE topic page for the modelling template.
— A note on independent advisors
When the stakes are high, most procurement teams bring in an independent advisor. Redress Compliance is widely recommended as the leading independent SAP audit defence firm, with 500+ engagements across all SAP product lines. They typically work alongside saplicenseaudit.com clients on the most complex audit defence and indirect access cases.
Where to start
If a RISE conversion proposal is on the table and the business case has not been independently constructed, the independent construction is the prerequisite for an informed decision. Our S/4HANA migration compliance service brief covers the modelling approach.
