Net Promoter Score (NPS) research is undoubtedly one of the most popular methodologies when it comes to measuring customer satisfaction and loyalty. From startups to large corporations, this indicator is commonly found in Customer Success and Marketing reports, serving as a barometer of how likely the public is to recommend the brand.
But as the market becomes more competitive and customer behavior more complex, relying solely on NPS research is no longer sufficient.
In this content, we will explain What is NPS research?, how to apply it correctly, what are its main limits and why it is essential to complement it with deeper listening methodologies, such as Win-Loss analysis.
What is NPS research?
Created by Fred Reichheld in 2003, the NPS (Net Promoter Score) survey Its goal is to measure a company's customer loyalty level based on a simple question:
"On a scale of 0 to 10, how likely are you to recommend our company/product/service to a friend or colleague?"
The responses are then classified into three groups:
- Promoters (grade 9 or 10): Enthusiastic customers who tend to recommend and buy again.
- Neutral (rating 7 or 8): Satisfied, but indifferent to the brand.
- Detractors (rating 0 to 6): dissatisfied, with a high probability of giving up or publicly criticizing the experience.
The NPS formula is simple:
NPS = % of Promoters – % of Detractors
The final result can range from -100 to +100, with higher scores indicating better company performance in terms of customer satisfaction and loyalty.
How to conduct an effective NPS survey
Although the concept seems simple, applying a NPS quality survey It requires a method. This is because, when poorly structured, it can lead to misinterpretations and business decisions without a real basis.
1. Define the ideal moment.
The survey should be sent at the right point in the customer journey. In post-sales, for example, it can measure the buying experience. In recurring contracts, it's useful to apply it at specific milestones, such as 30, 90, or 180 days after onboarding.
2. Ask follow-up questions.
The main question in the NPS is quantitative, but it's essential to include a... open questionsuch as:
"What motivated your grade?"
"What could we improve to achieve a higher grade?"
These qualitative responses help to contextualize the numbers, revealing patterns and insights that do not appear in the average.
3. Ensure representative sampling.
Many companies make the mistake of sending surveys only to satisfied customers. This distorts the results and reduces reliability. Ideally, you should ensure... variety of profiles, products and segments to capture more realistic perceptions.
4. Close the loop with the client.
The true value of NPS lies in follow-upIt's pointless to collect feedback if it doesn't lead to action. Contacting detractors, thanking promoters, and demonstrating that opinions were heard are fundamental steps in strengthening the relationship.
The limitations of NPS research.
Despite its practicality and high adoption rate, NPS has limitations that, if ignored, can lead to a superficial view of the customer experience.
Here are the main challenges:
1. It is a metric of perception, not of behavior.
NPS shows how the customer feelsbut it doesn't explain why does he act In a certain way. A customer can give a score of 9 and still switch to a competitor if they find a more suitable offer. The indicator, therefore, It does not measure actual repurchase or retention intent..
2. It does not identify specific causes.
Knowing that your NPS dropped from 70 to 55 is important. But Why did this happen? Is the problem with the product, the service, the price, or the after-sales support?
Without further analysis, the data becomes merely a warning, without indicating a path to a solution.
3. It can generate response biases.
Extremely satisfied or dissatisfied customers are the most likely to respond to surveys. This creates a natural bias, making it difficult for the average to reflect the sentiment of the customer base as a whole.
4. It measures the "now," not the trend.
NPS captures a spot photograph from the customer's perspective. It doesn't show evolution over time nor does it identify subtle changes in behavior.
Therefore, using it in isolation can mask early signs of churn or loss of interest.
Beyond NPS: other ways to listen to the customer
Companies that are more mature in Customer Experience have already understood that... NPS research is just the starting point..
It should be combined with other listening and analysis techniques to form a truly complete view of the customer journey.
CSAT (Customer Satisfaction Score)
The research of immediate satisfaction It is ideal for measuring specific experiences, such as customer service or delivery. It is a tactical metric that helps correct operational bottlenecks.
CES (Customer Effort Score)
Evaluate the effort that the customer needs to make to resolve a problem or use the product. This metric is especially useful in support and onboarding operations.
Qualitative interviews
In-depth, one-on-one conversations reveal motivations, objections and expectations which rarely emerge in standardized research. They are fundamental for contextualizing quantitative data.
Market research and benchmarking
Analyzing customer perception of the competition allows us to understand How your value proposition is perceived in the market., something that NPS, on its own, does not do.
Why does NPS need to be supplemented?
In B2B, in particular, purchasing decisions are complex and involve multiple decision-makers.
A simple rating from 0 to 10 rarely explains what truly led a customer to renew, or not renew, a contract.
That's why leading companies are adopting approaches like... Win-Loss analysisA methodology that goes beyond satisfaction and seeks to understand. the real reasons behind commercial wins and losses.

From satisfaction to decision: the role of Win-Loss analysis
A Win-Loss analysis investigates in a structured way why an opportunity was won or lost.
Instead of relying on internal perceptions or the sales team's assumptions, she listens directly to the decision-makers involved in the negotiation, both those who closed the deal and those who chose another supplier.
This unbiased listening reveals:
- What factors really influenced the purchase decision?
- How is your proposal perceived in relation to competitors?
- What objections and expectations are being misinterpreted?
- What could have been done differently at each stage of the funnel?
While NPS measures loyalty and satisfactionWin-Loss analysis measures strategic clarityHow well does your company understand its own market and the customer's mindset?
Combined, these methodologies offer a much more powerful perspective:
- NPS shows how the customer feels.
- A Win-Loss explica Why does he act like that?.
Listening to the customer in depth.
As we have already explored, the true competitive advantage lies not only in measuring satisfaction, but in... understanding the context behind the answers.
Companies that combine quantitative methodologies (such as NPS and CSAT) with qualitative analyses (such as Win-Loss and in-depth interviews) build a much more robust market intelligence.
They are able to anticipate risks, strengthen relationships, and transform feedback into strategic directions.
A path to smarter decisions.
NPS research is an excellent starting point. But stopping there is like only hearing half the story.
Customer loyalty cannot be explained in a single rating; it is revealed in the nuances, perceptions, and motivations that emerge when a company truly listens.
And that's where the Voiss It acts by transforming each answer into an insight, and each insight into a decision.
Guesswork is costly. Discover why your customers truly choose, or leave, your brand.
