10 Types of Customer Service Call centers
Customer service call centers can have different roles. Some answer incoming calls, while others make outbound calls. Many individuals manage multiple platforms, including social media, email, and chat. Businesses can select the ideal arrangement by being aware of the many sorts. They can achieve their objectives and deliver first-rate consumer experiences thanks to this decision.
Inbound Call Centers

Making calls to current or future clients to facilitate business expansion is the primary goal of an outbound customer care call center. These centers manage telemarketing, product or service promotion, lead generation and qualification, and customer follow-up. They also set up appointments or send reminders, perform market research, and collect feedback via surveys. This kind of customer service call center helps businesses reach out and build stronger connections with their audience.
Help Desks
The purpose of a technical support customer service call center is to assist users with operational and technical problems, frequently within an enterprise.

Additionally, these centers respond to inquiries concerning internal procedures and offer advice to maintain system functionality, which enhances efficiency and productivity.
Virtual Call Centers

10 Critical Customer Service Call Center KPIs
In a customer service call center, KPIs (Key Performance Indicators) are essential for tracking how well the team is doing and how satisfied customers are. These KPIs help managers assess the call center's performance, including how quickly it handles calls and what customers need. By tracking these numbers, a customer service call center can improve service quality, make customers happier, and identify problems early before they escalate.
First Call Resolution (FCR)
This shows how many customer problems are fixed during the first call without needing a follow-up.
FCR= Total Contacts Resolved on First Contact/ Total Contacts x 100
Average Handle Time (AHT)
This shows the average time an agent spends on a customer's issue, including talking, hold time, and work done after the call.
AHT=Total talk time + Total hold time + After-call work time/ Total number of calls
Customer Satisfaction Score (CSAT)
This shows how satisfied customers are with the service they receive, usually measured through a quick post-call survey. A higher score means happier customers.
CSAT=Number of satisfied customers/ Total number of survey responses×100
Net Promoter Score (NPS)
This calculates how likely customers are to recommend your service to others, based on a scale of 0–10. It helps understand customer loyalty.
NPS=%Promoters−%Detractors
Average Speed of Answer (ASA)
This indicates how quickly agents respond to customer calls after entering the queue. Faster answers mean less customer frustration.
ASA=Total wait time for all answered calls/ Number of answered calls
Call Abandonment Rate
This calculates the percentage of customers who hang up before speaking to an agent. A high rate usually means long wait times or poor IVR navigation.
Call Abandonment Rate=Number of abandoned calls/Total incoming calls×100
Service Level
This shows the percentage of calls answered within a set time limit, such as 20 seconds. A higher service level means faster service for customers.
Service Level=Number of calls answered within target time/ Total number of calls×100
Occupancy Rate
This measures how much of an agent's working time is spent talking to customers or doing related tasks. A very high occupancy rate may cause stress, while too low a rate means underutilization.
Occupancy Rate=Total handling time/ Total logged-in time×100
Call Transfer Rate
This is the percentage of calls agents pass to another person or department. A lower rate usually means agents can handle most calls themselves.
Call Transfer Rate=Number of transferred calls/ Total calls handled×100
Average After-Call Work (ACW) Time
This is the average time agents spend finishing related tasks after ending a call, such as updating records or sending emails. Keeping ACW short helps increase efficiency.
ACW Time=Total ACW time/ Total calls handled
