Businesses can track the number of customer requests they handle without necessarily knowing how customers actually perceive their service. CSAT, NPS, and CES are three common metrics for measuring customer experience, but each answers a different question.
What Are CSAT, NPS, and CES?
CSAT – Are Customers Satisfied?
Customer Satisfaction Score (CSAT) measures how satisfied customers are with a specific experience, typically through a survey immediately after a transaction or support request is completed.
For example: “How satisfied are you with the service you just received?”
CSAT is suitable for evaluating specific touchpoints, such as the quality of a hotline interaction, how an employee handled a request, or the customer experience after a purchase.
CSAT = % of satisfied customers
A high CSAT indicates that the experience at a particular touchpoint is meeting customer expectations, but it only reflects a specific moment in the customer journey.
NPS – Are Customers Willing to Recommend?
Net Promoter Score (NPS) measures how likely customers are to recommend a business or product to others.
A common question is: “On a scale of 0–10, how likely are you to recommend our business to a friend or colleague?”
Customers are divided into three groups:
- Promoters (9–10): Customers who are likely to recommend the business.
- Passives (7–8): Relatively positive customers who are not yet strongly engaged.
- Detractors (0–6): Customers who may have negative experiences or are less likely to recommend the business.
NPS = % Promoters – % Detractors
NPS is suitable for tracking customer engagement and overall perception, typically through periodic surveys.
CES – How Easy Was It for Customers to Resolve an Issue?
Customer Effort Score (CES) measures how easy customers feel it is to complete an action or resolve an issue with a business.
For example: “How easy was it to resolve your issue?”
CES is particularly useful for customer service, where businesses want to understand whether customers have to complete too many steps, wait too long, or contact multiple teams to receive support.
CES helps businesses identify friction points in the process, rather than simply evaluating the final outcome.
How Are CSAT, NPS, and CES Different?
These three metrics do not completely replace one another. A customer may be satisfied with how an employee handled a request (high CSAT) but still find the process too complicated (low CES) or may not be sufficiently engaged to recommend the business (lower NPS).
When Should You Use CSAT, NPS, and CES?
Use CSAT to Evaluate Specific Touchpoints
If the goal is to understand whether customers are satisfied with a specific interaction, CSAT is a suitable choice.
For example, after a hotline team resolves a request, the business can send a CSAT survey to evaluate support quality and identify touchpoints with lower satisfaction levels.
Use NPS to Track Long-Term Customer Relationships
NPS is suitable for periodic surveys when businesses want to understand how customers perceive the brand and how willing they are to recommend it.
This metric is particularly useful for tracking trends over time or comparing different customer segments.
Use CES to Identify Friction Points
If customers frequently have to move between departments, provide the same information multiple times, or complete too many steps, CES can help identify where the problem lies within the process.
Instead of only asking, “Are customers satisfied?”, businesses can also ask “What is making the experience more difficult for customers?”
Should Businesses Use All Three Metrics?
Businesses can combine all three metrics when they want a more complete view of customer experience:
CSAT → Measures satisfaction at specific touchpoints
CES → Measures the ease of the customer service process
NPS → Measures overall customer engagement
For example, if CSAT declines after a business changes its support process and CES also decreases, the data may indicate that customers are finding the new process more difficult. On the other hand, if CSAT remains strong at individual touchpoints while NPS declines, the business may need to examine the broader customer experience.
How Does CRM Support Customer Service Quality Measurement?
Survey metrics become more valuable when they are connected to customer data and interaction history. A CRM can centralize CSAT, NPS, and CES results alongside customer information, assigned employees, communication channels, and resolved requests.
This allows managers to understand not only whether scores are increasing or decreasing, but also which customers, channels, or processes may be associated with those results. This provides a stronger basis for identifying issues and making specific improvements instead of simply monitoring overall scores.
Conclusion
CSAT, NPS, and CES measure three different aspects of customer experience: CSAT focuses on satisfaction, NPS reflects customer engagement and willingness to recommend, while CES measures how much effort customers need to put into completing a request.
Businesses do not necessarily need to implement all three from the beginning. What matters more is identifying what needs to be measured, choosing the right metric, and connecting survey results with operational data. When managed centrally through a CRM, these metrics can provide a data-driven foundation for improving customer service quality.
