Poor customer service

Poor customer service leaves customers feeling let down: a phone that rings unanswered, staff who seem uninterested, a delivery that arrives late with no apology, or a complaint that is shrugged off. The damage goes well beyond the one sale that is lost.

A damaged reputation

A business's reputation is what customers believe about it, built from their own experiences and from what others say. Unhappy customers post one-star reviews and tell friends, family and workmates, and that word of mouth puts off people who have never used the business. Many who are treated badly simply switch to a competitor and never come back.

Lower sales, market share and profit

The effects then run in a chain. Customers switching means fewer sales, so revenue falls. As rivals win those customers, the business's market share, its slice of all sales in the market, shrinks. Profit falls from two directions: less revenue coming in, and money spent on discounts or advertising to win back trust.

Lost repeat business

Repeat customers are the dependable part of future sales: the people who return for servicing, refills or an upgrade without being persuaded. Poor service breaks that habit, so income becomes less steady and more must be spent finding replacements. If enough customers leave, the fall in sales can threaten the business's survival.

Worked example: A bike repair workshop keeps a customer's bike a week longer than promised and then charges her again to fix a brake fault it had missed. She posts a one-star review, tells her cycling club, and moves her twice-yearly servicing to a rival shop. The workshop loses that repeat business and the club's recommendations, its sales and market share slip, and the owner spends on posters and a discount to attract new customers, which cuts profit further.
