Common Mistakes with CSM

Running CSMs as reactive support with a fancier title — success is proactive: adoption plans, business reviews, and renewal forecasting.
Overloading the book: a CSM covering far more than ~$2M ARR (or too many logos) can only firefight, and NRR shows it.

CSM FAQ

What does a CSM do?

A customer success manager owns accounts after the sale: onboarding to first value, driving adoption, running business reviews, catching churn risk early, and setting up renewals and expansion. The role converts a signed contract into retained, growing revenue.

How many accounts should a CSM manage?

The common sizing rule is $1–2M of ARR per CSM — fewer, deeper relationships in enterprise; more, tech-touch accounts in SMB. Compensation is often tied to the NRR of the book.
