In a highly competitive business environment, evaluating customer satisfaction and loyalty is not just a desirable practice but an essential one for any company seeking sustainable and predictable growth.
Although the Net Promoter Score (NPS) is one of the most popular metrics in the world of Customer Success, relying solely on it can lead to biased decisions that do not address all aspects of the customer experience.
In a highly competitive business environment, evaluating customer satisfaction and loyalty is not just a desirable practice but an essential one for any company seeking sustainable and predictable growth.
Although the Net Promoter Score (NPS) is one of the most popular metrics in the world of Customer Success, relying solely on it can lead to biased decisions that do not address all aspects of the customer experience.
Let's get started!
This blog explores what NPS is, how it compares to other key metrics such as Customer Satisfaction Score (CSAT) and Customer Effort Score (CES), and how these metrics can complement the overall evaluation of customer satisfaction and success. The goal is to provide a comprehensive view that allows companies to optimize their Customer Success strategy, generate higher retention, and ultimately drive sustainable growth.
What is NPS, and How Does it Differ from Other Customer Satisfaction Metrics Like CSAT and CES?
The Net Promoter Score (NPS) is a loyalty metric that measures how likely customers are to recommend your company, product, or service to others. It is calculated by subtracting the percentage of Detractors (customers who score 0 to 6) from the percentage of Promoters (customers who score 9 or 10). Those who respond with a 7 or 8 are considered Passives. NPS is primarily used to get an overall view of customer loyalty over time and identify potential areas for improvement in the customer experience.
However, NPS alone cannot measure satisfaction in specific interactions or reveal why a customer is dissatisfied. This is where the Customer Satisfaction Score (CSAT) and Customer Effort Score (CES) come into play:
CSAT measures customer satisfaction at specific touchpoints, such as a support interaction or purchasing experience, through surveys asking, “How satisfied are you with the service received?”
CES assesses the level of effort a customer needs to make to complete an action, like getting support or purchasing a product, using questions like “How easy was it for you to resolve the issue?” It is useful for identifying friction points in the customer experience.
The CES is ideal for evaluating the efficiency of processes like technical support, digital platform usability, or interactions with complex products. For example, if the CES score is low, it may indicate that customers are experiencing difficulties that need to be resolved to improve retention and satisfaction.
Why is NPS Alone Not Sufficient to Evaluate Customer Success?
Although NPS provides a good view of customer loyalty, it is not enough to understand the "why" behind the scores. This metric can become a “vanity metric” if not complemented with other metrics that delve deeper into the reasons behind the scores and measure specific touchpoints in the customer journey.
For example, a low NPS could be caused by multiple factors, such as issues with support, product usability, or billing friction. Without additional metrics like CSAT and CES, it is impossible to pinpoint the exact area that needs attention.
Key Customer Success Metrics That Companies Should Monitor
For a comprehensive evaluation, Customer Success teams should monitor a combination of metrics, including:
Customer Health Score (CHS): Measures the overall health of the customer by combining data from various sources (NPS, CSAT, CES, support interactions, product usage frequency, etc.) into a single score.
Churn Rate: Indicates the percentage of customers leaving the company in a given period. An increase in churn rate can signal issues with the product or service.
Customer Lifetime Value (CLV): Predicts the total value a customer will generate over their entire relationship with the company. It is crucial for measuring the ROI of retention and Customer Success strategies.

How Do NPS and CSAT Drive Sustainable Growth?
These metrics help companies better understand customers’ needs and expectations, enabling them to adapt products, services, and processes based on the results obtained. Here’s how these metrics contribute to sustainable growth:
Identification of Improvement Areas: Both NPS and CSAT help identify weak points in the customer experience. For example, a low CSAT score in support services may indicate a need for additional training or adjustments in the support process.
Retention Improvement: Addressing weak points and improving the customer experience can increase retention rates. High retention translates to more loyal customers who advocate for the brand, fostering long-term sustainable growth.
Increase in Customer Lifetime Value (CLV): Satisfied and loyal customers tend to spend more over time, increasing CLV. Additionally, these customers are more likely to try new products or services and make additional purchases.
Reduction in Customer Acquisition Cost (CAC): A high NPS means more customers willing to recommend you, generating organic growth through word-of-mouth. This reduces the need to invest large sums in acquiring new customers and lowers the CAC.
Feedback Loop for Innovation: NPS and CSAT allow companies to receive constant feedback. By actively listening to customers, companies can identify opportunities for innovation and create products and services that truly meet market needs.
Why Are NPS and CSAT Essential for Sustainable Growth?
Why Are NPS and CSAT Essential for Sustainable Growth?
When used together, these metrics help companies get a complete view of Customer Success and make informed decisions to improve the experience at each stage of the customer lifecycle. Here’s how they drive sustainable growth:
Identification of Weak Points: Both NPS and CSAT identify weak points in the customer experience. For example, a low CSAT score in support services may indicate a need for additional training or process adjustments.
Retention Improvement: By identifying and resolving weak points, companies can reduce churn rates. Retaining more customers increases profitability and reduces costs associated with acquiring new customers.
Increase in Customer Lifetime Value (CLV): Satisfied and loyal customers tend to spend more over time, increasing CLV. These customers are also more likely to try new products or services and make additional purchases.
Reduction in Customer Acquisition Cost (CAC): A high NPS generates organic growth through word-of-mouth. This reduces the need for large investments in customer acquisition, thereby lowering CAC.
How the Customer Effort Score (CES) Affects Customer Satisfaction and Retention
A high Customer Effort Score (CES) indicates that customers are encountering difficulties completing certain tasks, which increases the likelihood of churn. Conversely, a low CES score shows that interactions are smooth and easy, leading to higher customer satisfaction and a reduced propensity to switch to another provider.
Unlike other satisfaction metrics like NPS or CSAT, CES focuses on minimizing friction in the customer experience. This often results in higher levels of satisfaction and loyalty. A low CES score (indicating less effort required from customers) is generally associated with greater satisfaction and a lower churn rate, as customers prefer services and products that are intuitive and easy to use.
How is CES Measured?
CES is measured through surveys asking customers how easy it was for them to solve an issue or complete a particular action, using a scale of 1 to 7. Scores are interpreted as follows:
1-3: High effort (difficult to use or resolve)
4-5: Moderate effort
6-7: Low effort (easy to use or resolve)
CES is calculated as the proportion of responses that indicate "low effort" relative to the total number of responses.
Impact of CES on Customer Satisfaction and Retention
Lower Churn and Higher Retention: CES is directly linked to customer retention. According to Gartner studies, companies that manage to reduce customer effort tend to have a higher probability of long-term retention since customers who find it easy to do business with a company are more likely to continue their relationship.
Increased Overall Satisfaction: A low CES means customers find it easy to interact with the company, translating to higher satisfaction. Customers who experience fewer friction points have a more positive perception of the brand and are more willing to recommend it to others.
Enhanced Customer Experience: Reducing customer effort not only increases satisfaction but also improves the overall customer experience. Consumers increasingly value simplicity and efficiency, making it a competitive advantage to minimize the effort required to resolve issues or make purchases.
Boost in Customer Loyalty: CES predicts customer loyalty more accurately than NPS or CSAT in specific contexts, such as support interactions. A Gartner study found that 94% of customers who reported a “low effort” experience said they would buy again from the company, while 81% of customers with “high effort” experiences indicated they would be willing to share negative experiences.
Best Practices for Implementing These Metrics in a Customer Success Strategy
To implement these metrics effectively, the CasandraSoft team recommends the following:
Define a timeframe and specific touchpoints for data collection.
Use automation tools to distribute surveys and analyze results.
Complement NPS with open-ended questions to gain qualitative insights.
Implement a follow-up system to close the feedback loop with customers.
How Can SaaS Companies Use NPS and CSAT to Reduce Churn and Increase CLV?
SaaS companies face unique challenges when it comes to retaining customers and increasing their long-term value. Metrics like the Net Promoter Score (NPS) and the Customer Satisfaction Score (CSAT) are essential tools for monitoring customer satisfaction and making strategic decisions that drive retention and growth. Here’s how SaaS companies can use these metrics to reduce churn and increase Customer Lifetime Value (CLV):
Early Identification of At-Risk Customers: NPS enables segmentation of customers into Promoters, Passives, and Detractors. SaaS companies can monitor Detractors and prioritize attention to these customers to address their concerns before they leave the service. Implementing a proactive follow-up system with customers who receive a low NPS score helps identify problems before they become churn reasons.
Increasing CLV through Continuous Improvement: CSAT is useful for evaluating satisfaction at specific touchpoints, such as support interactions or onboarding completion. Monitoring CSAT at these stages allows SaaS companies to continuously optimize the customer experience. For example, if CSAT is low after the onboarding phase, customers may not fully understand how to use the software. In this case, the company can offer additional resources, such as tutorials or personalized training sessions, to reduce frustration and improve satisfaction. Satisfied customers tend to stay longer and consume additional products, thereby increasing CLV.
Proactive Customer Experience and Retention: NPS can also serve as an early indicator of changes in customer perception. By implementing regular NPS surveys, SaaS companies can capture trends in customer satisfaction and make proactive adjustments to their services. For example, a drop in NPS could alert the company to recent issues, such as poorly received software updates or changes in support quality. On the other hand, CSAT allows the company to monitor the impact of these improvements. If changes are made based on NPS feedback and subsequent CSAT scores indicate increased satisfaction, the company can confirm that the actions were effective. This not only reduces churn but also improves long-term customer loyalty.
Developing Upselling and Cross-Selling Strategies Based on NPS: NPS can also be used to identify Promoters, who are the most satisfied and loyal customers. These customers are ideal for upselling and cross-selling strategies. By focusing on these customers for additional products or premium service packages, companies can significantly increase CLV. Additionally, Promoters can be incentivized to participate in referral programs, which not only reduce churn but also help acquire new customers at a lower acquisition cost.
Closing the Feedback Loop and Continuous Improvement: One of the most effective practices is closing the feedback loop: collecting NPS and CSAT data, analyzing it, and taking action accordingly. SaaS companies should create a system that associates NPS and CSAT responses with specific actions, such as implementing product changes or improving customer service processes. For instance, if many Detractors report usability issues, the development team can prioritize improvements to the user interface. Closing the feedback loop ensures that changes are monitored and reflected in long-term customer satisfaction.
Conclusion
To achieve sustainable and predictable growth, companies must monitor metrics that encompass all aspects of Customer Success. NPS, CSAT, and CES are fundamental metrics that, when combined, provide a comprehensive view of customer satisfaction, retention, and growth potential.
Implementing these metrics strategically can help companies identify opportunities for improvement, strengthen customer relationships, and ensure long-term sustainable growth.
