Introduction

The Net Promoter Score (NPS) measures customer loyalty and likelihood of recommendation, while the Customer Effort Score (CES) measures how easily customers achieve their goal.

Many companies focus heavily on NPS, but research shows that ease (CES) has greater predictive value for customer retention and repeat purchases. In this article, we explain why a low CES often delivers more than a high NPS and how organizations can apply this.

NPS vs CES: a brief explanation

  • NPS: Measures how likely customers are to recommend your company.
  • CES: Measures how much effort a customer must make to achieve their goal.

NPS is valuable for loyalty; CES is essential for retention and efficiency.

Why ease is crucial

1. Customers leave companies because of frustration, not price

Research by Gartner shows that 94% of customers leave because of frustration with processes, not because of poor products or price.

2. Repeat purchases are influenced by effort

A customer who has to make an effort to place an order or resolve a problem makes repeat purchases less often, even if the experience is positive enough to give a high NPS.

3. CES predicts churn better

CES is a direct indicator of churn risk. Customers who have to make a lot of effort are more likely to churn than customers with a lower effort score, regardless of their NPS.

Examples in practice

  • E-commerce: Customers who experienced low effort when making returns were found to make repeat purchases more often, even if their NPS was average.
  • Telecom: Customers who could easily adjust their subscription through an app remained customers longer than those who could only make changes through a call center.
  • B2B SaaS: CES-optimized onboarding reduced support calls and increased contract renewals.

Implementing CES as a strategic tool

1. Measure at crucial moments

  • Purchase or registration
  • Support interaction
  • Contract renewal

2. Analyze feedback

  • Identify high-effort processes
  • Segment by customer value and behavior

3. Improve processes

  • Automation of repetitive tasks
  • Simple self-service and clear instructions
  • Fast and personalized follow-up

4. Combine CES with NPS

CES shows how easy things are for customers, NPS how loyal they are. Together, they provide a complete picture of the customer experience.

Pitfalls

  1. Only measuring: CES without action does not lead to improvement.
  2. No segmentation: Different customer groups have different expectations regarding effort.
  3. Confusing it with satisfaction: CES measures effort, not emotional satisfaction – both are important.

Conclusion

A low Customer Effort Score delivers more tangible results than a high NPS alone. Customers stay longer, make repeat purchases more often and become advocates when processes are simple and smooth.

Organizations that use CES strategically increase customer retention, loyalty and revenue in a way that NPS alone often cannot predict.
