The math

What the research says about timelines

ASUG surveyed 194 members in 2026. The average S/4HANA go-live took about 1.4 years. Brownfield projects averaged 15.8 months and greenfield projects 20.2. Sixty-one percent finished on time, and 36% were delayed, mostly because of business change, underestimated complexity, and scope creep.

Averages are not your project. That is exactly why a check is worth doing before you commit.

Who it’s for

Two starting points

Already mid-migration or negotiating RISE or S/4 terms?

Get an independent check that your dates hold, and the documentation to support your next commercial conversation.

What we are not saying

ECC mainstream maintenance ends Dec 31, 2027. Extended maintenance through 2030 exists as a paid option, and we can help you decide whether and how to use it. We do not treat it as a plan. 2030 is a milestone, not a strategy.
