Ask five people which customer metric matters most and you'll get five different answers, usually because they're each optimizing for something different. NPS, CSAT, and CES aren't competing standards — they measure different things, at different points in the customer relationship. Picking the wrong one for the wrong moment is the most common mistake we see.
Net Promoter Score (NPS): long-term loyalty
The question: "On a scale of 0–10, how likely are you to recommend us to a friend or colleague?"
Respondents split into three groups: detractors (0–6), passives (7–8), and promoters (9–10). Your score is the percentage of promoters minus the percentage of detractors — so it can range from -100 to +100.
Use it when you want a single, trackable number for overall brand health, measured over time — quarterly or after major product changes, not after every interaction. It's a relationship metric, not a transaction metric.
Don't use it when you want to know why someone is unhappy about a specific support ticket or a specific checkout flow — NPS is too coarse for that. Pair it with an open-ended follow-up ("what's the primary reason for your score?") or you'll have a number with no explanation attached.
Customer Satisfaction (CSAT): moment-in-time sentiment
The question: "How satisfied were you with [this purchase / this support interaction / this feature]?" — usually a 1–5 star or numeric scale.
Use it when you want to measure a specific touchpoint right after it happens: right after a support ticket closes, right after checkout, right after onboarding. CSAT is a snapshot, and it decays fast — ask it too long after the interaction and you're measuring memory, not experience.
Don't use it when you're trying to capture how someone feels about your company as a whole. A great CSAT score on one support ticket says nothing about whether that same customer would recommend you to anyone.
Customer Effort Score (CES): how hard was this
The question: "How easy was it to [resolve your issue / complete this task]?" — typically a 1–7 agreement scale ("strongly disagree" to "strongly agree" with "this was easy").
CES exists because satisfaction and effort turned out to be different things: a customer can be satisfied with the outcome of a support interaction while still finding the process frustrating (three transfers, two repeated explanations). CES specifically isolates that friction.
Use it when you're trying to reduce churn driven by process friction — support, returns, account changes, anything with steps a customer has to get through.
Picking one (or more)
A rough rule of thumb:
| If you're measuring... | Use |
|---|---|
| Overall brand loyalty, tracked over time | NPS |
| A specific interaction, right after it happens | CSAT |
| How much effort a process took | CES |
Most teams that run all three use NPS quarterly, CSAT after every support ticket, and CES after specific high-friction flows (returns, cancellations, account recovery) — not the same survey, not the same cadence.
Setting these up in Surveyee
All three question types — the 0–10 NPS scale, star-rating CSAT, and Likert-style agreement scales for CES — are built in, and we have ready-to-use templates so you're not building the question wording from scratch:
- Customer Satisfaction template — CSAT plus an NPS follow-up
- NPS Survey template — the standard NPS question with a reason-for-score follow-up
Both are free to use, no account required until you're ready to publish and start collecting real responses.
