The Hidden Costs of Waiting: Why 2026 Is Your Decision Year

With SAP ECC mainstream support ending December 31, 2027, many organizations believe they still have time. The reality? Waiting is already costing you—and those costs compound every quarter.

The Timeline Reality Check

If you haven't started your S/4HANA journey, here's the math:

Typical enterprise migration timeline18-36 months
Partner selection & contracting3-6 months
Internal alignment & budgeting2-4 months
If you start planning today...Go-live: Q2-Q4 2028

Organizations starting in H2 2026 will miss the 2027 deadline, facing extended maintenance costs or third-party support decisions.

The Compounding Costs

Rising Maintenance & Support Costs

Extended maintenance premium (2025-2027)+2% of current license annually
Post-2027 third-party support (if not migrated)$150-300K+ annually
Security patching complexity15-25% more effort per incident
Legacy infrastructure inefficiency20-40% higher TCO vs cloud

Talent & Resource Scarcity

Consultant day rates (2026 vs 2024)+30-50% premium
Project delays from resource constraints3-6 month average slip
Internal talent retention (ECC experts leaving)Critical knowledge loss
Training new team on legacy systemDiminishing return

Competitive & Business Risk

Delayed access to embedded analyticsDecision speed gap
Missing AI/ML capabilitiesAutomation opportunities lost
Integration limitations (modern APIs)Partner ecosystem friction
Audit & compliance concernsIncreasing scrutiny

Example: A Mid-Size Manufacturer

Consider a $500M revenue manufacturer with 1,200 SAP users currently on ECC 6.0:

Cost ItemStart 2024Start 2026
Consultant rates$1,800/day$2,400/day
Extended maintenance (2 yrs)$0$320K
Resource availabilityGoodConstrained
Timeline riskLowHigh
Estimated cost premiumBaseline+$1.2-2.5M

What to Do Now

1

Complete a strategic assessment this quarter

Understand your options: RISE, GROW, on-premise S/4, or extended ECC continuity. Don't let the 2027 deadline force a decision—make an informed choice.

2

Secure budget commitment for Q2 2026

Even if you're not starting implementation, reserve budget now. Projects delayed for budget cycles lose 6-12 months.

3

Begin partner evaluation

The best implementation partners are already booking 2026-2027 capacity. Start conversations now even if you're not ready to commit.

4

Document your current state

Run custom code analysis, catalog integrations, assess data quality. This work accelerates any future project and enables accurate planning.

The Bottom Line

Every quarter of delay increases costs and risk. The 2027 deadline isn't just about support ending—it's about the compounding effects of waiting: premium consultant rates, resource scarcity, compressed timelines, and missed business opportunity. 2026 is your decision year. Use it wisely.
