CSAT (Customer Satisfaction Score)

Every company wants to know whether customers are happy with its services and products. But emotions are abstract. To manage service quality, you need to turn them into numbers. That is exactly why marketers, customer experience (CX) specialists and business leaders use CSAT, a metric that converts a customer's "like / don't like" into a concrete percentage. In this article, we take a structured look at how to measure this metric correctly, how it helps prevent customer churn and why, in 2026, businesses are betting on survey automation.
What is CSAT and why does it matter?
CSAT (Customer Satisfaction Score) is a customer satisfaction index that shows how well a product, a service or a specific step in the service journey meets the customer's expectations.
The defining feature of the metric is its focus on the moment. Unlike broad measures of brand loyalty, CSAT measures satisfaction here and now:
- How easy was it to place an order on the website?
- Are you happy with the delivery speed?
- Did the support agent resolve your issue?
Why businesses measure CSAT:
- Finding bottlenecks. A survey immediately after an interaction shows exactly where the customer experience breaks down (for example, the product is excellent but delivery disappoints).
- Responding quickly. CSAT lets you solve problems in real time. If a customer gives an agent 1 star, a manager can contact them the same day and resolve the issue before a negative review appears online.
- Evaluating changes. If you have updated your customer portal interface, measuring CSAT before and after the release shows whether users find it easier to use.
