Why Enterprise CSM Salaries Are Rising in 2026
The 2026 index highlights that companies continue to invest heavily in roles that drive long-term client retention and revenue growth. Enterprise and senior CSMs are now viewed as commercial roles, not purely service functions.
Key reasons for salary growth include:
1. Revenue Ownership
CSMs responsible for upselling and expansion revenue typically earn significantly more than those focused purely on support or adoption. Where expansion targets are attached, compensation structures often resemble sales roles.
2. Account Value & Complexity
CSMs managing £1m+ revenue accounts, multi-stakeholder buying groups, regulated sectors (e.g. financial services) and global customer environments command higher base salaries due to complexity and commercial risk.
3. Retention Track Record
Proven retention performance is one of the strongest salary drivers. CSMs who consistently protect and grow revenue secure packages at the top end of the range.
4. Strategic vs Transactional Portfolios
Lower-touch, high-volume portfolios (100–500 SMB accounts) typically sit in the £60k–£85k bracket. Strategic portfolios (1–10 enterprise accounts) drive six-figure base salaries.
Location & Market Impact
While London hybrid roles typically command the highest base salaries across commercial functions, fully remote SaaS businesses increasingly match London-level pay for senior CSM hires. Some professionals are choosing flexibility or equity over higher base salaries, particularly in VC-backed SaaS companies.
