Customer Service KPIs: 7 Numbers That Reveal How Good Your Team Really Is
The key customer service KPIs: first response time, first contact resolution, CSAT and more, with an interactive test of your team's reply speed and tips.
The key customer service KPIs are: average first response time, average resolution time, first contact resolution rate, customer satisfaction, unanswered chats, chats per agent, and the share resolved by the AI agent. The most important for WhatsApp sales is first response time, because customers ask several competitors at the same time.
01The seven KPIs
| KPI | What it measures | Suggested target |
|---|---|---|
| First response time | How fast you respond | Under 5 minutes during working hours |
| Resolution time | How fast requests are completed | Same day for most cases |
| First contact resolution | Answer quality | Above 70% |
| Customer satisfaction | Customer experience | Above 90% |
| Unanswered chats | Leakage | Zero |
| Chats per agent | Workload distribution | Balanced across the team |
| Share resolved by the agent | Automation efficiency | Rising month on month |
These targets are practical suggestions; adjust them to your business and team size.

03How do you improve first response time?
- An AI agent replies instantly to every new chat.
- Automatic routing instead of waiting for someone to pick up the chat.
- Quick replies for common questions.
- An alert when a chat goes unanswered beyond a set time.
- Cover nights and Fridays with the agent instead of extra shifts.

05Read the numbers together
Fast response time with weak resolution means quick replies that don't help. High satisfaction alongside unanswered chats means you are not even measuring the customers you lost. Read the KPIs together every week, per agent and per channel.
Key takeaways
- First response time is the most important KPI when selling on WhatsApp.
