What Is Customer Service? Definition, Importance, and How to Make It Great
Excellent customer service is more than an FAQ page or a 24/7 chat box. What truly sets your business apart is making every customer feel like their request is your top priority—through a thoughtful blend of empathy and swift action.
When you invest in building a strong customer support team, you’re not just solving problems—you’re creating loyalty. Loyal customers return, spend more, and help extend your brand’s longevity. Neglect it, however, and you risk not only losing business but also facing the sting of negative publicity online. For small businesses, mastering great customer service isn’t optional—it’s essential for growth and reputation.
What Is Customer Service?
Customer service is the way a business supports and communicates with customers who have questions, concerns, or needs related to its products or services. These interactions can happen in person, over the phone, or online. A company’s support team typically handles customer issues and provides solutions—whether that means replacing a faulty item, issuing a refund, or offering personalized guidance, like recommending the right product size.
Great customer service goes beyond solving problems—it creates positive experiences. When done well, it boosts customer satisfaction, strengthens brand loyalty, and encourages repeat business. In fact, Salesforce reports that 89% of customers are more likely to make another purchase after a positive service experience, while a Khoros survey found that 83% of consumers say responsive support increases their loyalty.
4 Types of Customer Service
To meet customer expectations, many businesses provide support across multiple channels—making it easy for people to get help in the way that suits them best. Below are four of the most common types of customer service you’ll encounter:
1. In-Person Customer Service
In-person customer service happens when employees interact directly with customers face-to-face. Common examples include assisting a shopper in finding a product, answering questions in a retail setting, or processing returns at a physical store. These personal interactions allow businesses to build trust, offer tailored support, and create a memorable customer experience.
2. Phone Customer Service
Phone support connects customers directly with a service representative over a call. This type of customer service is often used to handle account changes, resolve issues, or provide technical assistance. For example, a subscriber to a coffee delivery service might call to pause their subscription while traveling. Phone support offers a personal touch and allows businesses to resolve concerns quickly and efficiently.
3. Online Customer Service
Online customer service takes place through digital channels such as email, live chat, social media, or AI chatbots. This form of support is especially vital for ecommerce businesses, where customers already interact and shop online. Shoppers expect quick, convenient solutions through the same platforms they use to purchase—making online support a cornerstone of modern customer service.
4. Self-Service Customer Support
Self-service allows customers to find answers on their own through helpful resources such as FAQs, knowledge bases, step-by-step guides, or instructional videos. By empowering people to solve problems independently, businesses can reduce support volume while still delivering a positive, efficient customer experience.
What Makes Excellent Customer Service?
When engaging with customers—particularly those who may be frustrated or dissatisfied—there are several proven ways to deliver excellent customer service, including:
1. Study the Most Common Customer Service Issues
Strengthen your customer service operations by preparing your team to handle frequent questions and concerns. For example, a company that sells portable Bluetooth speakers might notice that customers often struggle with first-time pairing. By creating how-to articles, videos, and thorough training for support representatives, the business can resolve these issues quickly—saving time for both customers and the support team.
2. Show Patience and Empathy
Great customer service starts with listening carefully, acknowledging a customer’s frustration, and responding with genuine care. Refunds or replacements may solve the immediate problem, but empathy builds lasting trust. For instance, if a customer receives the wrong shirt just days before a wedding, a simple refund won’t erase the stress. A truly empathetic response might include an apology, a discount on a future order, or expedited shipping to turn a negative experience into a positive one.
3. Communicate Clearly and Accurately
Customers value honesty and transparency—especially when something goes wrong. Whether delivering good news or bad, be clear and direct. For example, if a product is backordered, it’s better to provide an accurate delivery timeline than to overpromise and risk disappointment. Consistent, truthful communication builds trust and strengthens customer relationships over the long term.
4. Respond Quickly and Follow Up
Timely support shows customers that you respect their time and value their business. Aim to address queries promptly and continue following up until the issue is fully resolved. If a solution takes longer than expected, provide a clear timeline and explain the delay. After resolving the issue, request customer feedback—it not only offers insights for improvement but also demonstrates your commitment to delivering an even better experience next time.
How Do You Measure the Impact of Customer Service?
Measuring customer service performance requires looking at both direct and indirect metrics. On one hand, businesses track interaction-specific data—such as response times, resolution rates, and customer satisfaction scores. On the other, they analyze broader business outcomes, including retention, repeat purchases, and overall revenue growth. Together, these metrics reveal how customer service influences both customer experience and long-term business success.
Metrics Directly Related to Customer Service
These metrics focus on the efficiency and effectiveness of your customer service team, measuring how well they handle customer needs in real time:
- Resolution Time
- Response Time
- Customer Satisfaction Score (CSAT)
1. Resolution Time
Resolution time measures how long it takes to fully solve a customer’s problem—from the moment they reach out to the moment the issue is resolved. Shorter resolution times often indicate efficient service, but speed alone doesn’t guarantee satisfaction. To get the full picture, pair this metric with customer feedback to ensure the solution meets expectations.
2. Response Time
Response time tracks how quickly a customer service agent replies after a customer reaches out. Unlike resolution time, which measures the full problem-solving process, this metric focuses solely on the speed of the initial reply. Fast response times show customers that their concerns are being acknowledged promptly—a key factor in building trust and satisfaction.
3. Customer Satisfaction Score (CSAT)
The Customer Satisfaction Score (CSAT) measures how happy customers are with a specific interaction or service experience. It’s typically calculated by sending a short survey and dividing the number of positive responses by the total number of responses. While CSAT provides valuable insight into customer sentiment, keep in mind that low response rates can affect the accuracy of your results.
Metrics Impacted by Customer Service
Beyond direct interactions, customer service also influences broader business performance. These metrics provide a more holistic view of how support impacts overall company growth and customer loyalty:
- Net Promoter Score (NPS)
- Customer Churn Rate
- Customer Lifetime Value (LTV)
1. Net Promoter Score (NPS)
Net Promoter Score (NPS) measures customer loyalty by asking how likely someone is—on a scale of 1 to 10—to recommend your business to a friend or colleague. While some NPS feedback reflects customer service, other factors such as product quality, pricing, and delivery also play a role. As with CSAT, reliable results depend on strong survey participation, making response rates critical for accuracy.
2. Customer Churn Rate
Customer churn rate—typically expressed as a percentage—tracks how many customers stop purchasing from a business over a given period. For ecommerce and subscription-based companies, this metric is especially useful for understanding customer retention. While churn can highlight issues with customer service, it also reflects other factors such as pricing, product quality, and overall customer experience.
3. Customer Lifetime Value (LTV)
Customer Lifetime Value (LTV) estimates the total revenue a business can expect from a customer throughout the entire relationship. A higher LTV signals stronger customer loyalty and long-term profitability. While excellent customer service plays a key role in extending customer relationships, other factors such as marketing strategy, product quality, and pricing also influence this metric.
