Relational vs transactional - two different questions, two different answers
NPS vs CSAT
NPS measures loyalty over time. CSAT measures satisfaction right now.
They answer different questions, run on different timelines, and diagnose different problems. Here's when to use each - and when to run both.
NPS vs CSAT at a glance
Net Promoter Score (NPS)
“How likely are you to recommend us?”
Customer Satisfaction Score (CSAT)
“How satisfied were you with this experience?”
When to use NPS vs CSAT
The most common mistake is using the wrong metric for the question you're actually trying to answer.
Use NPS when you want to know...
Is overall customer loyalty improving or declining?
Run quarterly. Track the trend over 4–8 quarters, not individual scores.
Which customers are most likely to refer others?
Promoters (9-10) are your referral engine. Study what they have in common.
Which customers are at churn risk before it happens?
Detractors (0-6) are warning signs. Follow up within 48 hours.
How does relationship health change after a major product update?
Run NPS before and after a significant release to measure the impact.
How do we compare to industry benchmarks?
NPS has widely published industry benchmarks. CSAT benchmarks are less standardized.
Use CSAT when you want to know...
How did our support team handle that ticket?
Send within minutes of resolution. CSAT on support is one of the most high-signal uses of the metric.
Did onboarding land the way we intended?
Trigger CSAT after the user completes the onboarding flow - not at day 30 when the context is gone.
How satisfied were users with this feature release?
In-product CSAT triggered on first use of the new feature captures immediate reaction before any habituation.
Where in the customer journey are we creating friction?
Map CSAT across every touchpoint to find where scores drop. Low CSAT at onboarding explains high early churn.
Did this purchase or upgrade meet expectations?
Post-transaction CSAT within 24 hours tells you whether the sales process set correct expectations.
Using NPS and CSAT together
NPS catches relationship drift. CSAT tells you which touchpoint caused it.
If your NPS is declining quarter over quarter but you don't know why, look at CSAT across your customer journey. The touchpoint with the lowest CSAT is usually the answer.
Warning pattern
NPS declining but you don't know where the friction is
High NPS overall but high early churn in a specific cohort
Support volume rising but NPS looks healthy
Onboarding CSAT low - but NPS doesn't show it yet
Combined signal
Run CSAT on support, onboarding, and first value moment separately
Track CSAT trend for each touchpoint alongside quarterly NPS
Low CSAT at onboarding + declining NPS = fix the activation flow first
High CSAT everywhere + declining NPS = pricing or competitive issue
Where does PMF fit in?
For early-stage SaaS, NPS and CSAT both miss the most important question.
NPS
"Would you recommend us?"
Loyalty indicator
You can have high NPS and still lose PMF - users like you but don't depend on you.
Post-PMF, quarterly, for companies with an established user base.
CSAT
"How satisfied were you?"
Experience indicator
High CSAT on support doesn't tell you if the core product is essential. Satisfaction ≠ dependency.
After every customer interaction, post-PMF, for operational improvement.
PMF Score
"How would you feel if you could no longer use it?"
Necessity indicator
Measures whether users actually need the product - the only question that matters before you scale.
Pre-PMF, every 3 months, until you hit 40%+ very disappointed.
NPS vs CSAT vs CES: choosing the right metric
The three most common SaaS feedback metrics - each answers a different question. Here is how they compare side by side.
NPS Net Promoter Score | CSAT Customer Satisfaction | CES Customer Effort Score | |
|---|---|---|---|
| Core question | "How likely are you to recommend us?" | "How satisfied were you?" | "How easy was it to get help?" |
| Measures | Long-term loyalty | Satisfaction with a specific interaction | Friction in a specific task or support interaction |
| Scale | 0–10 | 1–5 or 1–10 | 1–7 (strongly disagree to strongly agree) |
| Indicator type | Lagging - reflects past experience | Lagging - reflects past interaction | Leading - predicts future churn |
| When to send | Quarterly, to active users | After every key interaction | Immediately after support or onboarding |
| Best for | Tracking overall brand health over time | Measuring quality of support or specific features | Identifying friction that causes churn |
| Churn prediction | Moderate - detects unhappy users | Moderate - flags poor interactions | Strong - high effort = high churn risk |
| Actionability | Low - score doesn't tell you what to fix | Medium - tied to specific touchpoint | High - points directly at process or UX friction |
Which metric should you use?
You want to track overall brand health and growth potential
NPS is the best metric for understanding your relationship with customers at the account level. Run it quarterly. Use it to track trends, not individual responses.
You want to measure quality of a specific support interaction or feature release
CSAT is transactional. Send it immediately after the interaction while it is fresh. CSAT scores on individual touchpoints tell you where your service breaks down.
You want to find what is causing churn before users cancel
High effort is the strongest leading indicator of churn. CES tells you where your product creates friction - onboarding, support, key workflows - before users decide to leave.
You want to run all three
NPS quarterly for brand health. CSAT after key interactions. CES after support and onboarding. They measure different things and do not overlap when timed correctly.
