"Provided excellent customer service" says nothing. CSAT, ticket volume, and resolution time say everything.
Support is measurable, so measure it. Show your satisfaction scores, how much volume you handled, the channels you covered, and the tools you used — that is what separates you from every other applicant.

ATS keywords for a customer service representative resume
Applicant tracking systems match your resume against the job posting. Weave these terms in where they are genuinely true — never pad with skills you don't have.
Bullet points, before and after
The pattern is the same every time: start with an action, add the detail, land on a result. Here it is on real customer service representative lines.
Before
Answered customer calls and emails.
After
Handled ~60 tickets a day across chat and email while holding a 96% CSAT.
Before
Helped resolve customer issues.
After
Cut average resolution time from 26 to 15 hours by building a reusable macro library in Zendesk.
Common mistakes to avoid
- No metrics — CSAT and volume are the whole game
- Generic "provided great service" with nothing behind it
- Leaving off your tools and the channels you covered
- No sign of handling difficult or escalated cases
How to structure it
Summary with your CSAT and volume, then a skills/tools line. Experience with metrics on each role; education last. This resume can lean lighter on education and heavier on numbers.
Frequently asked questions
My old job did not track metrics. What do I use?
Estimate honestly and label it as such ("~50 tickets/day"), or use outcomes you do know — repeat customers, escalations you resolved, a process you improved. Some specificity beats none.
Which tools should I list?
The ones in the job posting first, then the platforms you genuinely used (Zendesk, Salesforce, Intercom). Naming the exact tool helps you clear ATS filters.
