Winning New Customers or Keeping the Ones You Have?

You spend on boosted posts to pull in strangers. You knock a little off the price to close a first sale. Meanwhile the customers you already paid to win go quiet, and one day you notice they have drifted to the stall next door. So where should your effort really go: chasing new faces, or keeping the ones you have?

Quick answer

A shop that looks busy but stays thin

Picture a phone-and-accessories trader in Kumasi. Every month she pays for boosted posts and shaves a few cedis off her prices to pull in new buyers. The shop looks busy. Yet at month-end the takings are thin.

Why? Most of those new faces buy once, then vanish. The regulars who used to come every week, the ones who already trusted her, have quietly gone elsewhere because nobody made them feel remembered. She is working hard to fill a bucket that leaks from the bottom.

The pattern: it costs more to win than to keep

This direction is widely accepted in business¹. You will see eye-catching claims that put an exact multiple on it, saying keeping a customer is so many times cheaper than winning one. Be careful with those. The exact multipliers cannot be traced to any solid study, so we will not repeat them as fact. The honest, well-grounded truth is the direction, not a magic number. Keeping is usually cheaper than winning.

And a kept customer keeps paying you back. This is why retention is more than a cheaper sale:

• They buy again. One good customer over a year is worth many single visits. A cosmetics seller in Lagos with forty regulars who each spend ₦3,000 a month has a far steadier business than one chasing forty strangers who buy once.
• They cost less each time. No fresh advert, no discount to tempt them, no trust to rebuild from scratch².
• They bring others. A word from a happy customer is the most trusted promotion there is, more than any advert you could buy³. Your best customers double as your cheapest sales force.

A kept customer keeps paying you back in ways a single ticket never shows.

Put together, that stacking is why small gains in keeping customers tend to pay off out of all proportion to the effort. In Reichheld’s studies of service businesses, keeping just a few more customers each year lifted profits by a wide margin. Treat that as a direction to trust, not a promise: it was modelled work in the United States in the 1990s, in another market and time, not a rule measured in an African shop^4,5.

Decide: you don’t have to choose all-or-nothing

Winning and keeping are not really enemies. A happy regular refers a friend, so money spent keeping customers quietly buys you new ones too.

For most small traders, a sensible starting point is to spend the larger share of your time and money on keeping the customers you have, and a smaller share on winning new ones. Not half and half, and not everything on the chase. If you are barely known yet, you will lean more toward winning. Once you have a base of regulars, protect it first. Then adjust as you watch what actually works.

One caution: keeping customers does not mean chasing every single one equally. Some buy often and stay for years; some haggle hard, buy once, then are gone. How much a customer is worth over the whole time they stay is their lifetime value, the total profit you make from them, start to finish⁶. It tells you who is worth the most effort. That is the subject of a separate article on customer lifetime value.

Act: a few retention routines that cost little

You do not need software. You need habits.

• Know your regulars by name. Keep a simple contact list, even a WhatsApp group, of the people who buy from you. Message them when new stock lands.
• Give the reward to loyalty, not to strangers. Instead of another discount to tempt a first-timer, keep a small thank-you for the customer who came back: a little extra, or first pick of new goods.
• Fix the reasons people leave. Most customers who never return are not angry, just quietly disappointed. Knowing why they go is half the battle, covered in why customers never come back.
• Ask for the referral. A happy customer will gladly send a friend if you simply ask.

Steady regulars do one more thing for you: they smooth out your cash. Predictable repeat sales make next week’s money easier to plan, which matters most in a trading business where cash runs tight, as why profitable businesses run out of cash explains.

Measure: watch your repeat rate

The number to watch is simple. Each month, ask: what share of my sales came from people who had bought from me before? You do not need exact figures to start. Even a rough sense of “more regulars this month, or fewer?” tells you whether the bucket is filling or leaking.

When you are ready to move past a rough sense, the Monyvo App can help here: it lets you track which customers keep coming back and what each one is worth to you over time, so the repeat rate becomes a number you can actually watch month to month rather than a feeling. It is one honest way to see, early, whether your best regulars are staying or slipping. See the Monyvo App.

An honest note on the evidence: the solid African research on customer loyalty so far looks at formal businesses like telecoms and online stores, not the informal trader on the street^7,8. The pattern still holds up. Just treat it as a well-grounded principle rather than a local number measured in a shop like yours.
