Concept
What is Customer Success and how is it different from support?
Customer Success (CS) is the function that ensures each client gets maximum value from your product. It does not wait for the client to have a problem: it anticipates, proposes and accompanies. Customer success has a direct impact on NRR; Paddle explains the metrics that link the two in how customer success teams drive revenue retention.
Support is reactive (client calls, you help). CS is proactive (you call before there is a problem). Companies that implement CS reduce churn by 67% and their NRR exceeds 120%.
In B2B, where each account is worth thousands, not having Customer Success is like driving without a rearview mirror. You can move forward, but you cannot see what is about to hit you. Retention depends on it.

Customer Success is preventing fires, not putting them out
Checklist: Do you have Customer Success in your company?
Customer Success is a proactive function that ensures each client gets maximum value from your product or service. Unlike support (reactive), CS anticipates problems, detects expansion opportunities and reduces churn before it happens.
What is the difference between Customer Success and support?
Technical support is reactive: it responds when the client has a problem. Customer Success is proactive: it contacts the client before there is a problem, analyzes their product usage and proposes improvements. It is the difference between putting out fires and preventing them.
