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?”

Type: Relational - measures the overall relationship
Scale: 0–10 (Promoters 9-10, Passives 7-8, Detractors 0-6)
Output: Score from -100 to +100
Timing: Quarterly or after major milestones
Best for: Loyalty trends, churn prediction, referral likelihood
Benchmark: +30 is good, +50 is excellent (SaaS)

Customer Satisfaction Score (CSAT)

“How satisfied were you with this experience?”

Type: Transactional - measures a specific interaction
Scale: 1–5 (satisfied = rated 4 or 5)
Output: Percentage of satisfied respondents (0–100%)
Timing: Immediately after each interaction
Best for: Support quality, onboarding, feature releases
Benchmark: 80%+ is good, 90%+ is excellent (SaaS)

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.

NPS vs CSAT vs CES

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.
