In the fast-paced world of customer support, gut feelings don’t cut it—metrics do.
The difference between a high-performing support team and one that constantly plays catch-up often comes down to how well the leader understands and manages Key Performance Indicators (KPIs).
Think of KPIs as the compass for your support ship—they guide decisions, highlight blind spots, and keep everyone rowing in the right direction. But tracking numbers alone isn’t enough; you must know why they matter and how to act on them.
In this blog, we’ll break down the essential KPIs every support team leader must master, along with real-world examples and scenarios.
1. Customer Satisfaction Score (CSAT)
What it measures:
The percentage of customers who are satisfied after a support interaction, usually captured through a quick survey (“How satisfied are you with the help you received?”).
Why it matters:
It’s the most direct measure of how well your team meets customer expectations.
Scenario:
Imagine your monthly CSAT drops from 92% to 85%. After digging into survey comments, you find that customers are frustrated with the long hold times during peak hours. By adjusting your staffing schedule to match ticket spikes, the next month’s CSAT rebounds to 91%.
Pro Tip:
Track CSAT by agent as well as for the whole team—this helps identify top performers and those who may need coaching.
2. Average Handle Time (AHT)
What it measures:
The average time spent from the start of a customer interaction to the end of the interaction (including talk time, chat duration, and after-call work).
Why it matters:
A high AHT may mean your team is struggling with efficiency, but a very low AHT could indicate rushed, incomplete solutions.
Scenario:
Your AHT for live chat is 11 minutes, but the industry benchmark is 7 minutes. After shadowing a few agents, you notice they spend time looking for information scattered across multiple tools. You introduce a central knowledge base, and within a month, AHT drops to 8 minutes without affecting CSAT.
Pro Tip:
Pair AHT with First Contact Resolution (FCR) to avoid chasing low AHT at the cost of quality.
3. First Contact Resolution (FCR)
What it measures:
The percentage of customer issues resolved in the first interaction, without needing follow-up.
Why it matters:
High FCR reduces workload, improves customer trust, and boosts satisfaction.
Scenario:
Your FCR is 65%, but your goal is 80%. Reviewing repeat tickets, you discover that password reset requests often require escalation because agents lack permissions. Granting secure access to these functions allows agents to solve the problem on the spot, raising FCR to 78%.
Pro Tip:
Monitor FCR per channel—email might have a lower rate than chat due to delays in back-and-forth communication.
4. Average Speed of Answer (ASA)
What it measures:
The average time it takes for a customer to connect with a support agent after initiating contact.
Why it matters:
Slow responses frustrate customers and can impact CSAT, even if the eventual resolution is excellent.
Scenario:
During a product launch, your ASA jumps from 30 seconds to 3 minutes. You temporarily reassign back-office staff to handle live chat greetings, triaging issues before passing them to specialists. This keeps customers engaged and drops ASA back under a minute.
Pro Tip:
For omnichannel teams, measure ASA separately for phone, chat, and social media DMs—each has different customer expectations.
5. Ticket Backlog
What it measures:
The number of unresolved tickets at any given time.
Why it matters:
A growing backlog signals staffing or process issues that could lead to burnout and poor customer experience.
Scenario:
Your backlog grows by 200 tickets after a holiday weekend. Reviewing the cases, you notice many are simple status updates. You set up automated emails to inform customers about order progress, cutting unnecessary tickets by 15%.
Pro Tip:
Track backlog trends over time to anticipate seasonal surges and prepare resources in advance.
6. Customer Effort Score (CES)
What it measures:
How easy it was for customers to get their issue resolved, usually rated from “very easy” to “very difficult.”
Why it matters:
Even satisfied customers might not return if they had to jump through too many hoops.
Scenario:
CES surveys reveal that customers find your IVR menu confusing. You simplify the options and add a “speak to agent” shortcut. As a result, CES improves, and you notice a drop in call abandon rates.
Pro Tip:
Combine CES with CSAT to get a clearer picture—customers might rate you high on satisfaction but low on effort, which is a future churn risk.
7. Cost per Ticket
What it measures:
The total cost of handling a ticket, including salaries, tools, and overhead, divided by the total number of tickets.
Why it matters:
Helps justify budgets and make decisions on automation, outsourcing, or hiring.
Scenario:
You find that phone tickets cost $9 each compared to $3 for chat. By shifting certain inquiries to chatbots and live chat, you reduce the total monthly support cost by 18% without lowering quality.
Pro Tip:
Use cost per ticket data in quarterly business reviews (QBRs) to show how your team delivers ROI.
8. Agent Utilization Rate
What it measures:
The percentage of an agent’s work hours spent actively handling tickets or calls versus idle or on breaks.
Why it matters:
Too low = wasted capacity. Too high = burnout risk.
Scenario:
You discover utilization is at 95% for two months straight. Burnout signs appear—agents take longer to reply, and errors increase. Hiring one extra part-time agent drops utilization to 80%, improving morale and quality.
Pro Tip:
Aim for a healthy range (typically 75–85%) to keep your team productive without overloading them.
9. Missed Chat or Call Rate
What it measures:
The percentage of customer inquiries that go unanswered.
Why it matters:
Missed contacts directly translate to lost sales and dissatisfied customers.
Scenario:
Your missed chat rate spikes during lunch breaks. You stagger breaks and introduce an “Away” auto-message with alternative resources, cutting missed chats by 50%.
Pro Tip:
Automate greetings to hold customers until an agent is available—it reduces drop-offs.
10. Employee Satisfaction Score (ESAT)
What it measures:
How happy and engaged your support agents are in their roles.
Why it matters:
Happy employees create happy customers. ESAT is a leading indicator of turnover risk.
Scenario:
A quarterly ESAT survey reveals a drop from 88% to 72%. Agents cite outdated tools as a frustration point. After implementing a faster ticketing system, ESAT rebounds, and voluntary attrition decreases.
Pro Tip:
Review ESAT alongside customer-facing KPIs—low ESAT often correlates with declining CSAT.
