Success versus support

Support answers questions and fixes problems when a customer asks. Customer success works ahead of problems: it helps customers reach the results they bought the product for, so they renew and grow. A customer success manager, often called a CSM, owns a group of accounts and their outcomes.

What a CSM does

CSMs onboard new customers, run check-ins and business reviews, watch usage and health, coordinate with support and product teams, and prepare renewals. In subscription businesses this role directly affects revenue, because customers who see value stay and buy more.

  • Onboarding
  • Check-ins and reviews
  • Health monitoring
  • Coordination with support and product
  • Renewals and expansion

How CSMs are measured

Common measures include renewal rate, expansion revenue, customer health and satisfaction. Good CSMs also bring feedback to the product team, which improves the product for everyone.

Worked example: a quiet customer

A CSM notices a clinic group has stopped logging in. Instead of waiting for renewal, she calls, learns that the staff member who used the product left, and runs a short training for the new person. Usage returns and the group renews.

Common beginner mistakes

Customer success is proactive. Waiting for customers to call is support, not success.

  • Only reacting to tickets
  • Not knowing the customer's goals
  • Ignoring usage data
  • Talking about renewal only at renewal time
Key takeaways
  • Support reacts; success works ahead of problems.
  • CSMs own customer outcomes.
  • Renewals and expansion are key measures.
  • Watch usage and act early.
