What Should Indian Enterprises Budget for SAP S/4HANA?
An SAP S/4HANA programme is an enterprise-scale investment, and the budget spans more than software: licences, infrastructure (cloud or on-premise HANA), implementation services, data migration, change management, and post-go-live support. The total depends most on your approach — a brownfield conversion of a healthy SAP ECC system costs less than a greenfield rebuild — and on landscape complexity. Budget for the whole programme, not just the licence, and start the assessment early ahead of the 2027 ECC deadline.
The Cost Components of an S/4HANA Programme
1. Software licences — S/4HANA itself, priced by deployment model (RISE with SAP / cloud subscription, or on-premise licences).
2. Infrastructure — the HANA in-memory platform, on a hyperscaler (AWS, Azure, OCI, GCP) or on-premise.
3. Implementation services — the partner-delivered programme: design, configuration, custom code remediation, testing, and cutover. Usually the largest line.
4. Data migration — extracting, cleansing, and loading data, often from years of ECC history.
5. Change management and training — frequently underbudgeted, and a common reason projects underdeliver.
Approach Decides the Budget
| Approach | What it is | Cost profile |
|---|---|---|
| Brownfield (system conversion) | Convert existing ECC in place, keep history and config | Lower — faster, reuses what works |
| Greenfield (new build) | Fresh S/4HANA with redesigned best-practice processes | Higher — more design and change effort |
| Selective / hybrid | New core plus selective migration, phased by entity | Varies — manages risk for complex groups |
What Pushes the Number Up
Heavy custom code (more remediation), many integrations, multiple legal entities and countries, poor data quality, and aggressive timelines all increase cost. The single biggest cost-control lever is an honest readiness assessment up front: it sizes custom code, data quality, and the conversion gap so every later decision is evidence-based rather than a surprise.
How ROSTAN Helps You Budget
ROSTAN Technologies starts every SAP S/4HANA engagement with a readiness assessment that sizes the real scope — custom code, data quality, integrations, and the right approach (brownfield, greenfield, or hybrid) — with Indian GST and e-invoicing compliance built into the plan. That gives you a grounded budget and timeline, worked backward from the 2027 deadline, before you commit to the full programme.
