What Is Customer Success?
Before diving into the role, let’s define Customer Success.
Customer Success is a proactive, strategic function that helps customers achieve their desired outcomes while using a product or service. Unlike Customer Support, which reacts to problems, Customer Success anticipates them—and works to prevent them.
Who Is a Customer Success Manager and what does he do (CSM)?
A Customer Success Manager acts as the bridge between the company and its customers. Their primary mission? To ensure customers gain maximum value from the product, stick around longer, and become brand advocates.
They combine elements of support, account management, consulting, onboarding, training, and strategy—all rolled into one.

The CSM:

-
- Conducts monthly check-ins to analyze feature usage
-
- Identifies that they aren’t using the reporting dashboard, so schedules a training
-
- Flags low adoption of mobile features and helps optimize the rollout
-
- Before renewal, present a value summary showing time saved

Result: The client renews, expands their plan, and refers two more agencies.
