S/4HANA Implementation Costs: Complete Budget Guide
Understand the true cost of S/4HANA implementation, from licensing to hidden expenses. Build an accurate budget before you commit.
Cost Breakdown by Company Size
| Cost Category | Small/Mid | Enterprise | Global | Notes |
|---|---|---|---|---|
| Software Licensing | $500K - $2M | $2M - $10M | $10M - $50M+ | S/4HANA + HANA database + BTP credits |
| Implementation Services | $1M - $5M | $5M - $25M | $25M - $100M+ | SI fees, typically 2-4x license cost |
| Infrastructure | $100K - $500K/yr | $500K - $2M/yr | $2M - $10M/yr | On-premise or cloud hosting |
| Internal Resources | $500K - $2M | $2M - $10M | $10M - $30M | Backfill, SME time, PM |
| Change Management | $200K - $500K | $500K - $2M | $2M - $10M | Training, communications, adoption |
| Testing | $200K - $500K | $500K - $3M | $3M - $15M | Test automation, UAT, regression |
| Data Migration | $100K - $300K | $300K - $2M | $2M - $10M | Data cleansing, migration, validation |
| Contingency | $300K - $1M | $1M - $5M | $5M - $20M | 15-25% of total budget |
| Total Range | $3M - $12M | $12M - $60M | $60M - $250M+ |
* Ranges are indicative and vary significantly based on scope, complexity, approach (greenfield vs brownfield), and geographic distribution. Always conduct detailed scoping.
Understanding Each Cost Category
1. Software Licensing
S/4HANA licensing includes the application itself plus the underlying SAP HANA database. Pricing models include perpetual licenses (upfront + annual maintenance) or subscription (annual fee including updates).
- • S/4HANA license: Based on users and revenue
- • HANA database: Based on memory allocation
- • BTP credits: For extensions and integrations
- • Additional modules: Industry solutions, analytics, etc.
RISE Comparison
RISE with SAP bundles license + infrastructure into a subscription. Initial costs are lower but 5-year TCO is often similar.

System integrator (SI) fees are typically the largest cost component, often 2-4x the license cost. This includes project management, configuration, development, testing support, and go-live assistance.
- • Tier 1 SIs (Accenture, Deloitte, IBM): Premium rates, global capability
- • Tier 2 SIs (specialized SAP partners): Competitive rates, deep expertise
- • Offshore/nearshore: Cost savings but coordination overhead
- • SAP consulting: Product expertise, premium pricing
Watch Out
Initial estimates often exclude: scope changes, extended testing, data issues, and post-go-live support. Budget 20-30% contingency.
3. Internal Resources
Often underestimated, internal costs include your team's time commitment, backfill for BAU activities, and dedicated project resources.
- • Project team: Full-time PM, architects, leads
- • SME time: Business process owners, super users
- • IT support: Basis, security, integration teams
- • Backfill: Replacing people pulled to project
Rule of Thumb
Plan for 50-100% of SI cost in internal resources. A $10M SI engagement needs $5-10M in internal time.
Hidden Costs Most Organizations Miss
Custom Code Remediation
30-50% of custom objects need modification. Often $1-5M for brownfield migrations.
Integration Rework
APIs change, middleware needs updates. Budget $500K-$3M for integration modifications.
Data Archiving
Reduce data volume before migration. Often $200K-$1M for archiving strategy and execution.
Extended Hypercare
Post-go-live support often extends beyond plan. Budget 3-6 months additional support.
Productivity Loss
Users are slower initially. Factor 10-20% productivity impact for 3-6 months.
Scope Creep
Additional requirements emerge. Industry average: 15-30% scope increase.
Greenfield vs Brownfield: Cost Comparison
Greenfield (New Implementation)
Best when: Business transformation is the goal, existing processes are outdated, willing to adopt SAP best practices.
Brownfield (System Conversion)
Best when: Current processes work well, heavy customization worth preserving, lower risk tolerance, faster timeline needed.
