The verdict in three sentences
In Nairobi, most stores spend their whole budget to acquire new customers and nothing to keep them. Yet acquiring costs about 5 times more than retaining, and your top 20 % of customers drive 50 to 70 % of revenue. A points program reignites re-purchase at marginal cost.
The retention math
Retention isn't a luxury, it's margin. A program member re-purchases 25 to 40 % more often than a non-member (rough 2026 estimate).
| Metric | Non-member | Program member |
|---|---|---|
| Annual purchase frequency | Baseline | +20 to 35 % |
| 90-day re-purchase rate | Baseline | +25 to 40 % |
| Average basket | Baseline | +5 to 15 % |
| Cost to generate it | Acquisition (~5x) | Retention (~1x) |
| Share of revenue (top 20 %) | — | 50 to 70 % |
The message is simple: a customer you've already won is your most profitable asset. A program reactivates them instead of letting them slip away.
Points, cashback or VIP tiers?
Three mechanics dominate. Mobile money cashback (M-Pesa, Airtel Money) speaks straight to the local market.
| Mechanic | Typical value | Best for |
|---|---|---|
| Points per purchase (1-3 % of basket) | 1 point = 10-30 FCFA | Frequency, simplicity |
| Mobile money cashback | 1 to 3 % returned | Local market, cash effect |
| VIP tiers (bronze/silver/gold) | Progressive perks | Big baskets, status |
| Referral (points to referee + referrer) | 1,000-3,000 FCFA / pair | Viral acquisition |
Rule: keep a point's value between 1 and 3 % of the basket. Too low, nobody joins; too high, you erode margin. A 20 to 40 % enrollment rate among buyers is a good first-year target.
Mini case study
Gessy runs a fashion store in Nairobi, average basket 25,000 FCFA, 200 active customers. She launches a program: 2 % in points + M-Pesa cashback. Over 6 months, member purchase frequency rises from 2.0 to 2.6 orders/year (+30 %). For 120 members, that's 72 extra orders, about 1,800,000 FCFA of added revenue, against a points cost of roughly 360,000 FCFA (2 %). Strongly positive net return.

FAQ
Is retaining really cheaper than acquiring?
Yes: acquiring a new customer costs about 5 times more than retaining an existing one. And your top 20 % of customers generate 50 to 70 % of revenue.
What value should a point have?
Between 1 and 3 % of the basket. Below that, enrollment stalls; above it, margin suffers. Keep it simple: 1 point = a clear FCFA amount.
Mobile money cashback or classic points?
M-Pesa/Airtel cashback speaks louder locally because it's reusable cash. Points retain well if the reward conversion is clear.
What enrollment rate should I target?
20 to 40 % of your buyers in year one is a good target. Offer enrollment at checkout, one click, with the mobile money number.
Does the program really increase sales?
Yes: members buy 20 to 35 % more often and re-purchase 25 to 40 % more at 90 days than non-members.
