What is customer service?
Customer service is the help and care a business gives its customers at every point of contact. It happens:
- Before the sale: clear information, a welcome, advice, easy ways to contact the business.
- During the sale: friendly, knowledgeable staff, short waiting times, easy payment.
- After the sale: delivery, installation, repairs, guarantees, refunds and follow-up.
Customers compare businesses not only on price and product but also on how they are treated. Service is often the reason people choose one shop over another.
Methods of good customer service
- Product knowledge: staff can explain features, prices and differences honestly, and recommend the right item, not just the dearest.
- Customer engagement: keeping in touch through loyalty schemes, newsletters, social media and feedback forms, so customers feel valued.
- Speed and convenience: short queues, quick replies to calls, emails and chats.
- Personal touch: using the customer’s name, remembering their needs.
- Post-sales service: delivery, installation, training, repair, servicing, guarantees and easy returns.
- Complaint handling: Listen, Apologise, Solve, Thank (L-A-S-T), then follow up.
The client consultation
In personal services (hairdressing, beauty, fitness, opticians, tailoring, IT support) a consultation comes before the work:
- Greet and settle the client.
- Ask and listen: what do they want, why, and by when? Open questions start with what, how, why.
- Check and examine: look at the condition (for example skin, hair or nails, or a broken device), and check for allergies or risks.
- Advise and agree: suggest options, price and time; get the client’s agreement (consent).
- Record: write details on a client record card: name, contact, needs, findings, treatment or products used, results, and next visit. Keep it private and safe.
The card means the next visit starts where the last ended, which customers notice and value.
Customer service and e-commerce
Online shopping changes service:
- Website and app: easy to use, clear photos, honest reviews, secure payment.
- Fast contact: live chat, chatbots, email and phone, with quick answers.
- Delivery tracking and clear delivery times.
- Simple returns and refunds.
- Online reviews spread fast: one bad experience can be read by thousands.
Consumer laws in many countries give buyers rights: goods must match their description, be of fair quality and be fit for purpose.
Benefits of good service (and costs of poor service)
| Good service | Poor service |
|---|---|
| Customer loyalty and repeat sales | Customers leave for rivals |
| Good reviews and word-of-mouth | Bad reviews spread online |
| Can charge a higher price | Must cut prices to compete |
| Stand out from competitors | Lower revenue and profit |
| Motivated, proud staff | More complaints, refunds, legal costs |
Good service costs money (training, more staff, generous returns), so a business must balance service with cost.
Key formulas and definitions
- Customer service = help before, during and after the sale
- L-A-S-T complaint handling: Listen, Apologise, Solve, Thank
- Consultation: Greet → Ask & listen → Examine → Advise & agree → Record
- Client record card: name, contact, needs, findings, treatment, results, next visit
- Loyalty → repeat sales + word-of-mouth → higher revenue
Worked examples
1. A phone shop trains staff in product knowledge. How does this help the business?
Staff can match each customer to the right phone and explain it clearly. Customers trust the advice, are less likely to return the phone, and recommend the shop to friends: more sales and fewer refunds.
2. A customer complains that a delivered pizza is cold. Use L-A-S-T to respond.
Listen to the whole complaint without interrupting. Apologise sincerely. Solve: send a fresh pizza or refund at once. Thank the customer for telling you, and follow up next order (e.g. a discount code).
3. A salon client wants a new hair colour. Describe the consultation and what goes on the record card.
Greet and seat her; ask what look she wants and look at photos; examine scalp and hair condition and do an allergy (patch) test; advise colour, price and time and get agreement. Record: name, contact, patch-test result, colour code, processing time, result, and next visit date.
4. An online clothing shop offers free 30-day returns, which costs money. Give one benefit and one drawback.
Benefit: customers feel safe buying without trying on, so more sales and loyalty. Drawback: return postage and unsellable items raise costs and can cut profit.
Common mistakes
- Thinking customer service ends at the payment desk: after-sales service is a big part of it.
- Treating a complaint as an attack: a well-handled complaint often creates a more loyal customer.
- Pushing the most expensive product instead of the right one: it causes returns and loses trust.
- Forgetting the cost side: excellent service needs training and staff time, which must be paid for.
