Customer success is the function and practice of proactively ensuring customers achieve their desired outcomes with your product or service. Unlike reactive support, it works ahead of problems to drive retention, expansion, and advocacy. For recurring-revenue businesses, it is a growth function, not a cost center.

Customer success is often mistaken for support, which is why it gets underfunded. Support waits for problems; customer success prevents them by making sure customers actually reach the outcome they bought. In a recurring-revenue business, that directly drives retention and expansion, which means it produces revenue rather than just costing money. Treat it as growth, not overhead.

Example:

Proactively guiding a client toward the result they wanted, before they struggle, protects the renewal and opens expansion, unlike support that only reacts to tickets.

How is customer success different from support?

Support reacts to problems customers raise. Customer success works proactively to ensure customers reach their desired outcomes, driving retention and expansion.

Why treat customer success as a growth function?

In recurring-revenue businesses it directly drives retention and expansion revenue, making it a contributor to growth rather than a cost center.
