CSAT (Customer Satisfaction Score)
CSAT (Customer Satisfaction Score) measures customer satisfaction with a specific experience — a support interaction, a purchase, an onboarding process. The customer rates it from 1 to 5 (or 1 to 10), and the result is the percentage of positive responses. It is one of the main customer satisfaction metrics, alongside NPS and CES: while NPS measures overall loyalty, CSAT captures satisfaction in the moment.
