Customer Success vs. Customer Support: What's the Difference?

Customer Support is reactive: a customer has a problem, they file a ticket, support resolves it. Customer Success is proactive: the goal is making sure the customer gets enough value from the product that churn and expansion revenue are managed before they become a support ticket at all.

The clearest way to see the difference is what each team measures. Support is judged on response time, resolution time, and CSAT on individual tickets - did we fix the thing, fast, and did the customer leave satisfied with that specific interaction. Customer Success is judged on retention, expansion revenue, and product adoption - is this account actually using what they're paying for, and are they positioned to renew or grow, independent of whether they ever filed a single ticket.

This is why bolting customer success as a label onto an existing support team, without changing what the team actually does, doesn't work. A support team waits for the phone to ring. A customer success function reaches out before the account goes quiet - tracking usage data, flagging accounts that have gone dark, running onboarding checkpoints, escalating internally when a customer's usage pattern suggests they're heading toward churn, weeks before that customer would ever think to open a ticket about it.

Small teams often can't afford to fully separate the two, and that's fine early on - one person can wear both hats. The mistake is not knowing which hat they're wearing at a given moment, and therefore never doing the proactive work, because reactive tickets always feel more urgent than a health-score email that could theoretically wait.

If your team is 100% support and 0% success, you'll find out about churn risk exactly when it's too late to do anything about it - which is the exact gap our Customer Success & Support Operations work is meant to close.
