Last call for S / 4HANA: The hidden cost of staying in ECC through 2027
By Renato Assis, Delivery Director, Ábaco Consulting.
How many times, when presenting an SAP rollout or migration project to the board, does the discussion get stuck on the question“ what is the real financial return of the initiative?” In 2026, the era of technology projects approved solely on the basis of technical updates or end-of-support arguments is over. Today, the biggest challenge for companies pursuing these transitions is not technical complexity but the difficulty of translating change into EBITDA margin improvement and cash protection.
It is precisely in this gap that the so-called‘ Invisible ROI’ exists and it is also where many vital initiatives are dangerously postponed. Yet migration to S / 4HANA can no longer be treated as a distant priority. Market realities impose a deadline that directly affects operational risk, with the definitive termination of SAP ECC maintenance scheduled for the end of 2027.
Although extended maintenance until 2030 is possible, it comes at a high cost, requiring additional fees of 2 % on annual contract values. Financially, this means paying more to preserve an obsolete platform that delivers no new innovation. The broader market context intensifies the pressure. A 2025 Gartner survey indicates that 61 % of ECC customers had not yet migrated or acquired S / 4 licenses. a premium for rushed delivery under intense pressure.
While deadlines create urgency, understanding the‘ Invisible ROI’ builds the true economic case. Too often, companies compare migration costs only with current licensing expenses. The more accurate comparison weighs the cost of today’ s inefficiencies against tomorrow’ s productivity gains.
A robust financial justification must go further by examining hidden on-premises expenses.
A robust financial justification must go further by examining hidden on-premises expenses, including server depreciation, energy consumption, cooling and specialised support teams, versus the efficiency, global security standards and elasticity of cloud operations.
SAP ECC frequently requires months of development to integrate new capabilities, whereas S / 4HANA Cloud provides embedded Artificial Intelligence, including Joule, and machine learning on a continuous basis. Leaders must therefore consider the opportunity cost of lacking access to this automation today.
To gain executive traction, organisations should map precisely where operations lose money. This may include excess inventory caused by limited visibility, tax penalties resulting from integration failures or prolonged accounting close cycles that absorb valuable time.
When true ROI is calculated, it becomes clear how standardisation and technology migration address these weaknesses, transforming operating expenditure into strategic investment. Difficulty in securing budget approval often stems not from the size of the investment but from its weak linkage to measurable financial outcomes.
Anticipating the 2027 talent crunch and avoiding unnecessary surcharges ultimately represents the most financially responsible course of action. Acting decisively protects competitiveness, strengthens resilience and ensures the organisation is positioned for sustainable growth beyond the maintenance deadline. •
For businesses, this signals an unprecedented resource bottleneck in the coming years. The law of supply and demand will be unforgiving: competition for consultancies and experienced professionals could significantly inflate project costs as 2027 approaches. Organisations that delay will likely pay
