SAP Customer and Market Share Statistics (2026)

SAP's ECC to S/4HANA move is now a 2027 deadline problem for many customers, and the numbers on adoption, budgets and market position often disagree with each other. This roundup collects the figures that matter for a sign-off decision, with the year and survey population stated for each one. Where sources conflict, we show the conflict rather than choose a winner.

Key takeaways

1. Adoption: where SAP customers stand

User-group surveys give the most current read on what runs where. The DSAG numbers come from a German-speaking sample, so they lean toward DACH and public-sector buyers, and the 2026 edition covers more large enterprises than the 2025 edition.

• In DSAG's 2026 investment report, 56% of respondents ran S/4HANA on-premises, up from 44% in 2024. DSAG, February 2026
• Over the same period, the share still running SAP ECC or the older Business Suite fell to 54% from 68%. DSAG, February 2026
• S/4HANA Private Cloud rose to 17% (11% in 2024), while Public Cloud slipped to 5% (6% in 2024). DSAG, February 2026
• For 2026 investment, 42% of respondents planned high or medium spend on S/4HANA on-premises, against 22% for private cloud and 6% for public cloud. Constellation Research, February 2026
• A Precisely and ASUG survey, released in November 2025, reported that 59% of respondents were fully or partly live on S/4HANA, up from 46% in 2024. We could not open the original release to confirm the figure, so treat it as secondary. DVW Analytics, 2026
• SAPinsider's 2025 report found 32% of respondents had already transitioned to S/4HANA, with another 27% in implementation. SAPinsider, 2025

2. Vendor scale and market share

SAP's market share depends on the method. Revenue-based and customer-count estimates from different firms do not agree, and we found no single authoritative figure.

• One revenue-based tracker put SAP's 2024 ERP revenue at $8.6 billion, or 6.57% of a $131 billion ERP applications market, and said Oracle had passed SAP at $8.7 billion (6.63%). The tracker attributes its market data to Gartner. Cargoson, 2025 (citing Gartner and Apps Run The World)
• A separate estimate puts SAP at roughly 22–24% of global ERP share, with Oracle at 11–13%. That same source says analyst estimates can differ by 10 to 30 percent in absolute size. ERP Software, 2026 (unaudited estimates)
• Another estimate uses published implementations and puts SAP at about 23% of revenue, a figure its authors label as their own estimate. ERP Research, 2026
• Within the same German-market source, SAP's share is quoted as about 38% in one place and about 35% in another. ERP Software, 2026
• For enterprise and installed-base segments in the DACH region, one comparison cites roughly one-third to 40%, and says the mid-market is far more fragmented. ERP Software, 2026
• Customer counts also vary. One tracker estimated 141,399 SAP ERP customers, or 2.0% of about 7 million ERP customers. Cargoson, 2025 A market-intelligence firm reports about 42,000 SAP buyers in distribution management alone. HG Insights, 2025
• In an October 2024 industry overview, SAP was described as having more than 440,000 customers in 180-plus countries. That figure is historical and is cited to SAP. HL, October 2024 (historical)

The overall ERP software market was measured by Gartner at $66 billion in 2024, up 11.3% from $59 billion in 2023, according to a summary of Gartner data. HouseBlend, 2026 (summarizing Gartner)

3. SAP's own numbers: cloud momentum

SAP's reported figures measure contracted cloud revenue, not the number of ECC systems that have moved. SAP does not publish a migration count for its ECC base, which is why analyst estimates are the main source for that question.

• Current cloud backlog reached €24.1 billion at Q3 2026, up 28% (26% at constant currencies). SAP, Q3 2026
• The Cloud ERP Suite portion of that backlog was €5.9 billion, up 29%. SAP, Q3 2026
• Cloud revenue for the first nine months of 2026 was €18.9 billion, up 23%, with cloud gross margin at 74.3%, slightly below the prior year. SAP, Q3 2026
• SAP expects constant-currency growth in current cloud backlog to slow slightly in 2026, after 25% growth in 2025. SAP, Q3 2026
• For full-year 2025, SAP reported that the number of customers using Joule grew ninefold, and that AI features were included in more than two-thirds of Q4 cloud orders. ASUG summary of SAP's Q4 2025 results, 2026
• RISE with SAP had been adopted by more than 6,000 customers as of October 2024. That figure is historical. HL, October 2024 (historical)

4. The ECC deadline and what it means for timelines

The support clock sets the planning horizon for most of the readers of this page. The dates below describe mainstream and extended maintenance, which is different from when a system stops working.

• Mainstream maintenance for ECC 6.0 on enhancement packages 6 to 8 ends on December 31, 2027. DVW Analytics, 2026
• Enhancement packages 1 to 5 left mainstream maintenance at the end of 2025. DVW Analytics, 2026
• Optional extended maintenance runs through the end of 2030, at a premium of two percentage points on the maintenance basis from January 2028. Of Ash and Fire, 2026
• Without extended maintenance, legal changes, support packages and response-time SLAs stop under customer-specific maintenance. Of Ash and Fire, 2026
• In February 2026, SAP announced a transition option that lets some large customers keep ECC until 2033. CIO.com, 2025
• Gartner's count: about 35,000 ECC customers, of which roughly 14,000 had migrated by the end of 2024. CIO.com, 2025 (Gartner)
• Gartner projects about 17,000 customers, nearly half the base, will still be on ECC in 2027, and about 13,000 in 2030. CIO.com, 2025 (Gartner)

Source: CIO.com, 2025, citing Gartner

DSAG respondents describe a later schedule. In their 2026 survey, 37% planned to migrate by 2027, while 49% planned to extend ECC maintenance and finish by 2030. Only 4% expected to wait until 2033. The DSAG and Gartner figures use different populations and dates, so they should not be read as a single trend.

Source: Constellation Research, February 2026 and Arkyn, 2026 (reporting DSAG 2026)

Two cautions apply to the DSAG trend. SAP conducted the 2025 edition and reached fewer large companies, while DSAG ran the 2026 edition with more large enterprises, though public-sector respondents were heavily represented. Constellation Research, February 2026

5. Migration outcomes: schedule, budget and quality

The most detailed outcome data comes from Horváth's 2025 study of 200 companies. It is one study, so the figures are useful as a pattern rather than a benchmark for your program.

• Of the 200 companies surveyed, 37 had completed their S/4HANA migration, and 57% were still in the middle of it. CIO.com, 2025 (Horváth)
• In more than six of every ten cases, the planned migration budget was overtaken. CIO.com, 2025 (Horváth)
• Projects ran about 30% longer than originally planned on average, and 46% of respondents would now estimate a longer duration. CIO.com, 2025 (Horváth)
• Nearly two-thirds of respondents reported severe or very severe quality deficiencies after completing the migration. CIO.com, 2025 (Horváth)
• Across all four measures, more than 60% of companies had deviations in budget, schedule or result quality. CIO.com, 2025 (Horváth)
• Gartner has worked with clients planning three- to seven-year migration projects. CIO.com, 2025 (Gartner)
• Costs reported in the same coverage ranged from about $2 million for a simpler migration to up to $1 billion for large, complex enterprises. CIO.com, 2025

Source: CIO.com, 2025, Horváth study of 200 companies (Q1 2025)

Panorama's broader ERP research points in a different direction on duration. Its 2025 report found average project timelines fell from 15.5 months to nine months. That covers all ERP projects, not S/4HANA migrations alone, so it does not contradict Horváth directly. Panorama Consulting, March 2025 Panorama's 2026 report found more than a quarter of organizations exceeded project budgets, with additional technology needs cited as the leading cause. Panorama Consulting, 2026

6. Budgets and priorities

ASUG's 2026 Pulse is the largest recent survey of SAP customers in the sources we reviewed on this question. It surveyed 663 ASUG members in December 2025. ASUG, 2026

• Budget constraints were the top challenge, cited by 61% of respondents, which is 7 points higher than the prior year. CIO.com, 2026
• ASUG's coverage attributes that pressure mainly to the migrations themselves, not to macroeconomic conditions. CIO.com, 2026
• Integration was the next challenge, cited by 48%. Arkyn, 2026 (reporting ASUG 2026 Pulse)
• In ASUG's 2025 survey, business process change was the top barrier to S/4HANA migration, for 49% of respondents. Arkyn, 2026 (reporting ASUG 2025)

7. Testing and quality

The sourced numbers on testing are indirect. Most of what we could verify concerns quality outcomes after go-live, which the Horváth figures above cover, and data quality, which Precisely and ASUG flagged as a critical problem alongside automation needs. The Precisely and ASUG survey did not provide a number for that finding in the coverage we could reach. Precisely, November 2025

• In ASUG's 2024 Pulse, 34% of respondents named automation as the most important focus area, behind integration and S/4HANA migration. This figure is historical. ASUG, 2024 (historical)

8. People and skills

• In ASUG's 2026 Pulse, 35% of respondents reported challenges keeping up with the pace of technology change, up from 29% in 2025. ASUG, 2026
• When asked which skill matters most, 59% named SAP S/4HANA expertise, and 36% named AI and machine learning. ASUG, 2026
• In ASUG's 2024 Pulse, 28% of organizations struggled to find internal staff with the skills to lead new projects. This figure is historical. ASUG, 2024 (historical)

9. AI adoption

AI usage is growing faster than production deployment. The ASUG and DSAG figures below show the gap between piloting and running AI in SAP landscapes.

• In ASUG research conducted in February 2026 with 142 members, 41% were actively piloting AI and 39% were building foundational knowledge. Only 24% had reached active deployment. CIO.com, 2026 (ASUG SAP AI Research)
• Microsoft Copilot was in use at 72% of those respondents. CIO.com, 2026 (ASUG SAP AI Research)
• In DSAG's January 2026 survey, 43% had implemented AI use cases, including tests and pilots. heise, 2026 (DSAG)
• In ASUG's 2026 AI research, the three most-cited enablers were clear governance and frameworks (40%), alignment with business processes (39%) and clear use cases (39%). ASUG, 2026

What this means for your sign-off

1. Plan the schedule on the outcome data, not the vendor's timeline. Horváth's finding that only 8% of completed migrations finished on schedule is a reason to build contingency into the test calendar before the business commits to a go-live date. See our S/4HANA migration by the numbers for how these figures map to test phases.
2. Treat the 2027 date as the planning horizon, and know which extension applies. Mainstream maintenance ends in 2027, extended maintenance costs more through 2030, and the customer-specific phase drops legal and support services. Read the ECC end of maintenance guide before you commit to a timeline.
3. Budget for quality, not just cost. When 65% of Horváth's respondents reported severe quality issues after migration, the sign-off should require evidence of quality gates, not only a go-live date. The phase-by-phase migration testing plan sets out the gates to use.
4. Build the testing capability before the crunch. ASUG's finding that 59% of members rank S/4HANA expertise as their top skill means test-team capacity will be contested. A Testing Center of Excellence is one way to hold that capacity across waves.
5. Judge AI claims against deployment, not pilots. With only 24% of ASUG AI respondents in active deployment, any AI-assisted testing proposal should show governance and a production path. Our SAP AI for practitioners guide covers what to ask before approving.
