What does a Customer Service Representative do?
A Customer Service Representative responds to customer inquiries and requests across multiple channels, answering questions about products, services, billing, and accounts. They troubleshoot problems, process orders, returns, refunds, and exchanges, and escalate complex cases to the right team while keeping the customer informed every step of the way.
CSRs document every interaction in a CRM or ticketing system, follow company scripts and policies, and aim to resolve issues on the first contact whenever possible. They are measured on metrics like customer satisfaction (CSAT), average handle time, first-call resolution, and response time, and they often upsell or cross-sell relevant products while delivering a positive experience.

How to put Customer Service Representative duties on your resume
Turn duties into quantified achievements by adding numbers: calls or tickets handled per day, CSAT or satisfaction score, first-call resolution rate, average handle time, or response-time SLA performance. Metrics prove you can manage volume and keep customers happy, which is far more convincing than "answered customer calls."
Tailor your bullets to the posting. If the job names a specific CRM like Salesforce or Zendesk, a channel like live chat, or a metric like first-call resolution, mirror that exact language to match the ATS keywords. Lead each bullet with a strong action verb, put the result first, and highlight the soft skills (empathy, de-escalation, conflict resolution) the employer emphasizes.
