01 The Big Shift from ECC: What Has Changed
Transitioning from SAP ECC to S/4HANA is a fundamental shift in pricing models and risk exposure. Under ECC, companies managed perpetual licences with named user types and annual maintenance. S/4HANA introduces subscription models (RISE), Full User Equivalents (FUE), Digital Access, and mandates SAP HANA as the database.
| Dimension | SAP ECC | SAP S/4HANA |
|---|---|---|
| Licence Model | Perpetual + 22% maintenance | Perpetual OR subscription (RISE) |
| User Metrics | Named users (Professional, Limited) | Named users or FUE (cloud) |
| Indirect Access | Ambiguous (led to lawsuits) | Formal Digital Access (9 document types) |
| Database | Choice (Oracle, SQL, DB2) | SAP HANA mandated |
02 The Licensing Spectrum: Perpetual, Subscription, Hybrid
Three primary models exist in 2026.
Perpetual On-Premise
One-time CapEx + 22% annual support. You own the licence. Best for long-term stability and control. Requires internal infrastructure management and SAP Basis team.
Subscription (RISE with SAP)
Annual OpEx per FUE. Bundles software, infrastructure, support. Best for speed and OpEx preference. Risk: vendor lock-in, no mid-term reductions, renewal escalation.
Hybrid
Mix of on-premises and cloud. Common during migration periods. Risk: dual-running costs and complex governance across two licensing models simultaneously.
03 Digital Access Deep Dive
SAP's Digital Access model charges by documents created in SAP via non-SAP systems. Nine document categories are defined, with tiered pricing and 0.2 weighting for Material and Financial documents. This is now a top audit focus area in 2025 to 2026.
High-risk scenarios include Salesforce creating orders in SAP, RPA bots generating transactions, IoT devices producing material documents, and any scenario with thousands of external users indirectly accessing SAP through third-party applications or portals.
04 FUE in Action: Calculations, Risks & Optimisation
Full User Equivalent (FUE) is the primary metric for S/4HANA Cloud and RISE. The conversion ratios are: 1 Advanced = 1 FUE, 5 Core = 1 FUE, 30 Self-Service = 1 FUE.
Key risks include mis-estimating your user mix at contract signing, minimum commitments (40+ FUE for private cloud, 35+ for public cloud), and no ability to reduce FUE counts during the contract term. Right-sizing from the start is critical because overpurchasing locks you into years of inflated subscription fees.
05 2025 Price Dynamics
SAP's pricing is deliberately opaque, but discounts of 30 to 70% are common in enterprise deals. Key dynamics include volume tiers, block pricing for Digital Access, true-ups, 22% support inflation on perpetual licences, and 5 to 7% cloud renewal uplift. Always pre-negotiate growth pricing and renewal caps before signing.
06 Common Failure Points
Shelfware
Buying more licences than needed. Paying support on 300+ unused licences is a common finding. SAP sales teams incentivise over-purchasing through volume discounts that look attractive but create years of wasted spend.
User Misclassification
Assigning Professional licences to users who only need Limited or Self-Service access. This is one of the most common and most easily correctable sources of SAP overspend. A single user reclassification can save $2,000 to $5,000 per year.
Cloud Creep
Uncontrolled addition of users, integrations, and modules in RISE environments. Without governance, departments add FUEs and BTP services that compound subscription costs without formal approval or budget allocation.
Wrong Package
Buying top-tier edition with modules you will never deploy. SAP offers multiple S/4HANA editions with different module bundles. Choosing the wrong package means paying for capabilities that sit unused for the entire contract term.
Dual-Running Costs
Running ECC and S/4HANA simultaneously for 12 to 24+ months during migration. This creates overlapping licence and infrastructure costs that can exceed $1M in avoidable spend. Negotiate dual-use rights to eliminate this exposure.
07 Matching Licensing to Corporate Strategy
Align licensing with M&A plans (consolidate contracts post-merger for volume discounts), cloud strategy (negotiate ability to trade perpetual licences for cloud credits), and AI/RPA deployments (bots require Digital Access or named-user licences). Every corporate strategic initiative that touches SAP has licensing implications that should be modelled before execution.
08 Red Flags and Deal Killers
No 5-Year TCO Model
Signing without a complete 5-year total cost of ownership model that accounts for migration, dual-running, BTP, renewal escalation, and Digital Access exposure.
Accepting First Offer
SAP's initial proposals are starting positions. Discounts of 40 to 70% are normal in enterprise negotiations. Accepting the first offer leaves millions on the table.
Ignoring Digital Access
Failing to assess and address Digital Access exposure before signing. This creates open-ended audit risk that SAP will eventually exploit.
No Renewal Price Protection
5 to 7% annual increases compound fast. Without caps, a $2M annual subscription becomes $2.8M within 5 years. Always negotiate maximum annual uplift caps.
Surrendering Perpetual Rights
Converting perpetual licences to RISE without verified economics. Once perpetual rights are surrendered, the leverage they provided is permanently lost.
No M&A or Divestiture Clauses
Failing to include provisions for corporate restructuring. M&A events without licence transfer rights create compliance gaps worth millions.
09 Negotiating a Better S/4HANA Deal
| Tactic | Expected Impact |
|---|---|
| Aggregate all SAP purchases into one deal | 10 to 20% better discount vs. piecemeal |
| Create competitive pressure (third-party support, Oracle/Workday alternatives) | Unlocks SAP's best discounts |
| Lock renewal pricing (max 3%/year caps) | Prevents 25 to 35% cost escalation |
| Pre-negotiate growth pricing | Same discount on mid-term additions |
| Negotiate dual-use rights (12 to 18 months) | Eliminates $1M+ dual-running costs |
| Address Digital Access proactively | Avoids audit exposure, best pricing |
10 Action Checklist: 5 Things to Do Now
Run a Complete Licence Baseline
Map every user, transaction usage, and licence type across your SAP estate. This baseline reveals shelfware, misclassifications, and optimisation opportunities before any negotiation begins.
Assess Digital Access Exposure
Count documents created in SAP from non-SAP systems across all nine document categories. Quantify your exposure before SAP does it for you in an audit.
Model Your 5-Year TCO
Compare perpetual vs. RISE vs. hybrid with realistic assumptions including migration costs, BTP, renewal escalation, and Digital Access. The cheapest option today is rarely the cheapest option over 5 years.
Review Contract Terms for Gaps
Check for renewal caps, M&A clauses, dual-use rights, and Digital Access provisions. Every missing term is a future cost risk that SAP will exploit at renewal or during audit.
Engage Independent Advisory
Benchmark pricing against comparable enterprise deals, identify savings opportunities, and strengthen your negotiation position with vendor-neutral expertise and market intelligence.

Frequently Asked Questions
Perpetual licensing is a one-time CapEx purchase where you own the licence permanently and pay 22% annual support. RISE with SAP is a subscription (OpEx) model where you pay annually per FUE and SAP bundles the software, infrastructure, and support. Perpetual gives you long-term cost certainty and control. RISE provides speed and simplicity but creates vendor lock-in, no mid-term reductions, and renewal escalation risk. The right choice depends on your TCO model, cloud strategy, and tolerance for subscription cost escalation over time.
Digital Access charges by documents created in SAP via non-SAP systems. Nine document categories are defined (sales orders, purchase orders, invoices, service confirmations, material documents, financial documents, etc.) with tiered pricing and a 0.2 weighting for Material and Financial documents. Any integration that creates documents in SAP (Salesforce to SAP orders, RPA bots generating transactions, IoT devices producing material documents) triggers Digital Access licensing obligations. This is now SAP's top audit focus area.
FUE (Full User Equivalent) converts different user types into a single metric: 1 Advanced user = 1 FUE, 5 Core users = 1 FUE, 30 Self-Service users = 1 FUE. Your total FUE count determines your subscription commitment and annual cost. For example: 50 Advanced (50 FUE) + 200 Core (40 FUE) + 1,500 Self-Service (50 FUE) = 140 FUE total. Key risks include mis-estimating your user mix, minimum commitments (40+ FUE for private, 35+ for public), and no ability to reduce during the contract term.
Discounts of 30 to 70% off list price are common in enterprise SAP deals. The level of discount depends on deal size, timing (SAP's Q4 October to December offers maximum leverage), competitive pressure (credible alternatives like Oracle, Workday, or third-party support), and aggregation (combining all SAP purchases into one deal improves discount by 10 to 20% versus piecemeal). Never accept SAP's initial proposal. Every term is negotiable including renewal caps, growth pricing, dual-use rights, and Digital Access thresholds.
The primary risks are: vendor lock-in (surrendering perpetual licence rights eliminates future leverage), renewal escalation (5 to 7% annual increases compound to 25 to 35% over 5 years without caps), no mid-term reductions (you cannot reduce FUE counts during the contract term even if your user population shrinks), Digital Access exposure (integrations creating documents in SAP trigger additional licensing obligations), and dual-running costs (running ECC and S/4HANA simultaneously during migration creates overlapping costs exceeding $1M).
SAP has set the ECC mainstream support deadline for 2027. After this date, organisations running ECC will need to either migrate to S/4HANA, purchase extended support at a premium, or accept reduced support coverage. This deadline creates urgency that SAP leverages in negotiations. However, it is important to note that extended support options exist and that SAP has previously adjusted deadlines. Do not let artificial urgency drive you into a poorly negotiated agreement.
