What this dot point is asking
You need to explain what customer service is and why good customer service is so important to a business, and to describe what happens when service is poor. Customer service is the help and care a business gives its customers before, during, and after they buy. Keep your answer practical and link good service to clear benefits (repeat customers, good word of mouth, more sales) and poor service to clear harms (lost customers, bad reputation, fewer sales).
The answer
What customer service is
Customer service is the help and care a business gives to its customers. It happens at three times:
- Before they buy - greeting customers, answering questions, giving advice.
- During the sale - serving quickly, being polite, getting the order right.
- After they buy - handling returns, sorting out problems, following up.
Good service is friendly, helpful, fast, and gets things right.
Why good customer service is important
Good customer service helps a business in several linked ways:
- Customers come back. Happy customers return again and again. This repeat business is steady income.
- Good word of mouth. Happy customers tell friends and family, and may leave good reviews online, bringing in new customers for free.
- A good reputation. A business known for good service stands out from rivals, even if prices are similar.
- More sales and profit. All of the above lead to more sales, which is the point of the business.
The effects of poor service
Poor service - rude, slow, or careless staff - harms a business:
- Customers leave and do not return, so the business loses repeat business.
- Bad word of mouth. Unhappy customers tell others and may post bad reviews, which puts off new customers.
- A bad reputation that is hard to repair.
- Lower sales and profit. Fewer customers means less income.
Why one customer is worth more than one sale
One happy customer is worth far more than the single thing they buy today, because they may return many times and bring in others. Likewise, one badly treated customer can cost a business many future sales through bad word of mouth. This is why every customer matters.
Examples in context
Example 1. A phone shop with patient staff. A customer who is unsure which phone to buy is helped patiently and given honest advice. They buy a phone and, because the service was so good, return for accessories and recommend the shop to family. The patient service before the sale turned one visit into several sales and new customers.
Example 2. A hawker stall with a long, friendly queue. A chicken-rice stall is always busy because the hawker is quick, friendly, and remembers regulars. Customers happily queue and bring friends. A nearby stall with rude, slow service stays empty even with similar food, showing how service, not just the product, decides which business wins.
Try this
Cue. State what customer service is, and describe one example of service before the sale and one after the sale. Remember service happens before (advice and greeting), during (serving), and after (returns and problems), so pick one from before and one from after.
Cue. Explain two benefits a supermarket gets from good customer service. Link each benefit to more sales - for example repeat customers who return, and good word of mouth that brings new shoppers.
Cue. Describe two effects poor service could have on a restaurant, and explain why these matter. Think about lost repeat business and bad reviews, then link both to lower sales and a damaged reputation.

(a) Customer service is the help and care a business gives to its customers before, during, and after they buy.
(b) Two benefits: customers are happy and come back again (repeat customers), and happy customers tell their friends and family, bringing in new customers by word of mouth. Both lead to more sales for the shop.
What markers reward: a correct meaning of customer service (help and care given to customers), and two clear benefits, each linked to more sales (repeat customers, good word of mouth, or a better reputation).
Original5 marksA restaurant gives poor service - staff are rude and slow. (a) Describe two effects this poor service could have on the restaurant. (b) Explain why one happy customer can be worth more than the single meal they buy.Show worked answer →
(a) Two effects: customers leave unhappy and do not come back (lost repeat business), and they complain to others or post bad reviews online, which puts off new customers. Lower sales and a worse reputation result.
(b) One happy customer can be worth more than one meal because they may come back many times (repeat business) and tell friends and family, who then visit too. So one happy customer can lead to many future sales, not just the one meal.
What markers reward: two real effects of poor service (lost repeat business, bad word of mouth or reviews), and a clear reason a happy customer is valuable over time (repeat visits plus recommending others).
