# Customer success

In short

Customer success is the function and practice of proactively helping customers achieve the outcomes they bought your product for. It focuses on adoption, value, and long-term relationships rather than only answering problems.

It is a core part of recurring revenue models. Customers who succeed renew, expand, and refer others, so customer success is often measured on retention and expansion.

## What a customer success team does

* **Onboarding:** Guides new customers to first value.
* **Adoption:** Helps teams use more of the product in ways that matter to them.
* **Health monitoring:** Watches usage and engagement to spot risk early.
* **Business reviews:** Regular meetings that tie product use to customer goals.
* **Renewals and expansion:** Prepares renewals and flags upsell opportunities, sometimes with sales.

## Customer success vs. support vs. account management

* **Customer support:** Reactive. Resolves issues customers raise.
* **Customer success:** Proactive. Works toward the customer outcomes that drive renewal.
* **Account management:** Commercial focus on contracts and growth. In some companies the roles are combined.

## How to run customer success well

### Segment customers

Give large accounts a dedicated manager and serve smaller ones with scaled programs such as emails, webinars, and in-app guidance.

### Define success with the customer

Agree on measurable goals at kickoff, then review progress against them. Say a customer wants to cut report time in half; the team tracks that outcome, not just logins.

### Use data to prioritize

A customer health score helps focus limited time on accounts that need it most.

## Common mistakes

* **Acting as support:** Reacting to tickets leaves little time for proactive work.
* **No link to revenue:** Without clear retention and expansion goals, the function is hard to evaluate.
* **Weak handoff from sales:** Customers should not have to repeat what they told sales.
