Key takeaways
- Track speed, customer feedback, and workload together.
- Review results by channel and issue type.
- Use each KPI to guide a clear fix.
Your support team works hard, yet customers still chase refunds, ask for order updates, and leave poor reviews. It feels frustrating to put in so much effort without knowing what needs to change.
When these problems go unchecked, repeat requests pile up. Your team faces more stress, and unhappy buyers have fewer reasons to shop with you again.
The right e-commerce customer service metrics help you spot where support falls short. This guide covers nine KPIs to track so you know what to fix, help customers faster, and earn their trust.
Which KPIs show how fast you solve issues?
Track first response time, average resolution time, and first contact resolution. Together, they show how long buyers wait and whether your team solves their problem.
First Response Time
This measures the wait from a new request to your first reply. Exclude auto-replies. Divide total wait time by the number of requests answered. Track email and chat apart to spot gaps in coverage.
Average Resolution Time
This tracks the full time from a case opening to its final fix. Divide total elapsed time for solved cases by the number solved. If refund cases take longer, check approval steps and payment delays.
First Contact Resolution
This is the share of cases solved in one contact, with no follow-up needed. Divide those cases by all cases, then multiply by 100. Give agents access to order details and clear refund rules.
Which KPIs show how customers feel?
Track CSAT, CES, and NPS to learn whether buyers liked the help, found it easy, and would recommend your brand.
Customer Satisfaction Score
CSAT measures how buyers feel about a support exchange. Divide positive survey replies by all replies, then multiply by 100. Review scores by issue type. A high overall score might hide poor service on returns.
Customer Effort Score
CES shows how easy buyers found it to get help. Ask them to rate ease on a fixed scale, then track the average. Keep the scale the same. Low ease scores point you toward steps to remove.
Net Promoter Score
NPS measures willingness to recommend your brand. On a 0–10 scale, promoters score 9–10 and detractors score 0–6. Subtract the share of detractors from promoters in percentage points. NPS reflects the whole brand experience, beyond support.
Which KPIs help you plan staff and costs?
Track ticket volume, backlog, and cost per resolution to see how much work arrives, what remains, and what each fix costs.
Ticket Volume
Count new cases each day or week. Tag them by cause, such as late orders or damaged goods. Compare volume with order count to see whether requests rise faster than sales.
Ticket Backlog
Count unresolved cases and track their age. Flag those past your service targets. If the queue grows each day, review staffing and delays before the next sale.
Cost per Resolution
Divide total support costs by cases solved in the same period. Include staff, tools, and overhead. Pair this KPI with CSAT and first contact resolution to judge whether lower costs still deliver good service.
