Customer Effort Score (CES)

Customer Effort Score measures friction. After a specific interaction, whether that's resolving a support ticket, completing onboarding, or using a particular feature, you ask the customer: "How easy was it to [do the thing]?" They respond on a scale, usually 1 to 7, where 1 is very difficult and 7 is very easy.

The insight behind CES is counterintuitive. Research from CEB (now Gartner) found that reducing customer effort is a stronger predictor of loyalty than exceeding expectations. Customers don't need to be delighted. They need things to not be annoying.

CES vs NPS

NPS asks how a customer feels about you overall. CES asks how a specific interaction went. That difference matters for SaaS teams because NPS tells you the relationship is healthy (or not), but CES tells you which touchpoints are creating friction.

A customer might give you an NPS of 8 overall but a CES of 2 on your billing settings page. NPS wouldn't surface that. CES catches the specific pain points that erode satisfaction over time.

Put simply, NPS is a thermometer. CES is a diagnostic tool.

Why effort predicts loyalty

The original CEB research found that 96% of customers who reported high-effort experiences became more disloyal, compared to only 9% of those with low-effort experiences. Effort is a stronger churn predictor than satisfaction for a straightforward reason: people tolerate a product that's merely "fine" as long as it doesn't make their life harder.

For SaaS specifically, effort compounds. A clunky settings page is annoying once. A confusing billing flow that creates a support ticket every renewal cycle erodes retention steadily.

When to measure CES

CES works best as a transactional metric, triggered after specific events:

• After a support ticket is resolved
• After completing onboarding or setup
• After using a new feature for the first time
• After upgrading, downgrading, or modifying a subscription

Don't send CES surveys unprompted or on a schedule. The question "how easy was it?" only makes sense immediately after the interaction it refers to.

Pair CES data with exit surveys to close the loop. CES tells you where friction exists while the customer is still around. Exit surveys tell you which friction points actually drove cancellations. Together, they build a complete picture of where your product is losing people.

CES and the bigger picture

CES is one input to a broader customer health score. High effort interactions, particularly repeated ones, should weigh against an account's overall health. A customer with great usage metrics but consistently low CES scores on support interactions is more at risk than their engagement numbers suggest.
