Customer effort score

Definition

Customer effort score: how ease drives loyalty

The customer effort score, or CES, measures how much work a customer has to do to get a problem solved, a purchase completed, or a request handled. Low effort predicts loyalty better than high delight. It’s a single-question survey, usually scored 1–7, that fires right after the interaction and captures friction while it’s still fresh.

The metric was popularised by Matthew Dixon, Karen Freeman and Nicholas Toman in their 2010 Harvard Business Review essay, “Stop Trying to Delight Your Customers”, which argued that reducing effort beats exceeding expectations.

CES sits alongside customer satisfaction (CSAT) and net promoter score (NPS) in the standard voice-of-customer stack, but it does a different job. CSAT tells you how a customer felt. NPS tells you if they’d recommend you. CES tells you why they might quit.

Key takeaways

  • CES asks one question, usually phrased “the company made it easy for me to handle my issue,” on a 1–7 agreement scale.
  • Gartner research found effortless service customers were 94% more likely to repurchase than high-effort ones.
  • CES fires right after an interaction so recall is sharp and root causes stay visible.
  • It complements CSAT and NPS — it doesn’t replace them.
  • Contact centres and BPOs use CES as an operational KPI, not just a satisfaction check.

How it works

CES asks a single agree-or-disagree statement, usually “the company made it easy for me to handle my issue,” right after a support ticket, chat, purchase or self-service session. Respondents pick a number on a 1–7 or 1–5 scale where higher means easier. The average across responses is the score.

Two versions dominate the field. CES 1.0 (2010) asked “how much effort did you personally have to put forth to handle your request?” on a 1–5 scale where lower was better. CES 2.0, which the Corporate Executive Board (now Gartner) introduced in 2013, flipped the phrasing and the scale so higher numbers signal easier experiences, closer to how CSAT and NPS behave.

A typical CES pipeline looks like this:

5. FixCoaching, script edit or product changeOps or product

The point isn’t the number — it’s step 4. A CES programme that doesn’t loop back into training and product design is telemetry without a steering wheel.

Examples

Named programmes make the metric concrete. Four teams, across three sectors and two continents, treat CES as an operational lever rather than a vanity number.

Zendesk, the San Francisco customer-service platform, ships CES as a native survey type inside its Support product, and its 2024 CX Trends report found 71% of consumers switch brands after a hard-to-resolve issue. Teams using Zendesk typically fire the CES prompt in the ticket-closed email.

HubSpot, the Cambridge, Massachusetts marketing and service platform, added a native CES tool to Service Hub in 2019 and now scores every closed conversation from the customer portal. Support leads see a dashboard filter that pairs low CES tickets with the agent who handled them, a fast path from data to coaching.

Vanguard, the Pennsylvania asset manager, publicly credits its CES-driven redesign of the account-transfer journey with cutting call volume double digits, a case study Gartner has cited since 2015. The fix was pure friction removal: fewer forms, no re-authentication, one confirmation email.

Australian Taxation Office (ATO) runs CES against its tax-agent portal every quarter and publishes the results in its annual report, a rare government transparency signal that treats effort as a public-service KPI.

FAQ

What’s a good customer effort score?

On the 1–7 CES 2.0 scale, most benchmarks put a healthy score at 5.5 or above, with anything under 5 flagging systemic friction. Qualtrics and Zendesk both publish sector benchmarks. SaaS and fintech tend to score higher than telco and utilities.

Is CES better than NPS?

Neither wins in isolation. CES is the sharper predictor of churn after a service event, while NPS captures brand-wide advocacy over time. Most mature CX teams run both, plus CSAT, and triangulate.

When should you send a CES survey?

Fire it right after the touchpoint you want to measure — ticket close, chat end, order delivery, onboarding complete. Waiting more than 24 hours drops response rates sharply and pollutes the memory of the specific interaction.

Can outsourcing partners be measured on CES?

Yes, and increasingly they are. Contact-centre BPOs in the Philippines and India often sign CES targets into their service level agreements, tying agent bonuses to score bands.

What’s the difference between CES 1.0 and CES 2.0?

CES 1.0 (2010) asked about effort directly on a 1–5 scale, lower being better. CES 2.0 (2013) reversed it to a 1–7 agreement scale where higher scores mean lower effort. Almost every modern tool uses 2.0.
