The verdict in three sentences
A flat delivery fee hides two opposite mistakes: you lose money on distant zones and you overcharge nearby customers, who abandon their cart. Precise zoning by neighbourhood aligns each fee with its real last-mile cost, protecting both margin and conversion. In Nairobi in 2026, a three-to-four-zone split typically recovers 5 to 8 points of net margin without scaring away local buyers.
Why a flat fee costs you money
Delivery cost is never flat: it depends on distance, traffic, fuel and delivery failure rate. A rider spending 45 minutes to reach a far estate structurally costs more than a 10-minute city-centre run. By charging everyone 2,000 FCFA, you subsidise distant orders with the margin of nearby ones — and push those local buyers toward cart abandonment, since 2,000 FCFA on an 8,000 FCFA purchase feels like an abusive 25% surcharge.
The right approach: measure real cost per zone, set a displayed fee slightly below it to stay attractive, then steer a differentiated free-delivery threshold that lifts the average basket without destroying margin.
The Nairobi zone grid (2026 order-of-magnitude estimate)
| Zone | Displayed fee | Average time | Share of orders | Net margin after delivery |
|---|---|---|---|---|
| CBD / Central | 1,000 FCFA | 30-45 min | 34% | 22% |
| Westlands / Kilimani | 1,500 FCFA | 45-60 min | 29% | 19% |
| Karen / Runda | 2,000 FCFA | 60-80 min | 21% | 15% |
| Outer suburbs (Ruaka, Rongai, Athi River) | 3,500 FCFA | 90-150 min | 16% | 11% |

The free-delivery threshold that protects margin
| Zone | Recommended free threshold | Observed average basket | Effect on basket |
|---|---|---|---|
| CBD / Central | 25,000 FCFA | 14,000 FCFA | +18% basket |
| Westlands / Kilimani | 30,000 FCFA | 16,000 FCFA | +15% basket |
| Karen / Runda | 40,000 FCFA | 22,000 FCFA | +12% basket |
| Outer suburbs | 50,000 FCFA | 19,000 FCFA | +9% basket |

The principle: the free threshold must stay above the average basket to remain profitable, yet close enough to nudge the customer into adding an item.
Mini case study
Awa, who runs an online cosmetics store, delivered everything at a flat 2,000 FCFA. On 300 orders/month split by the grid above, she lost about 1,500 FCFA of uncovered real cost on each outer-suburb delivery (16% of 300 = 48 orders), i.e. 72,000 FCFA/month of erosion. Switching to zoned pricing, she recovered those 72,000 FCFA and, thanks to the central fee cut to 1,000 FCFA, conversion in the central zone rose 6 points, adding around twenty orders. Estimated combined gain: about +250,000 FCFA of margin/month.
FAQ
Should the delivery fee show before checkout? Yes. A fee that only appears at the final step is the leading cause of cart abandonment, with rates climbing above 60% in some cases. Show an estimate from the product page or cart.
How many zones should you create? Three to four is enough for Nairobi. Beyond that, the complexity the customer perceives cancels the benefit. Group neighbourhoods by similar real cost, not by administrative map.
Does zoned pricing really cut conversion in expensive zones? Marginally, if the free threshold is well calibrated. Suburb customers accept 3,500 FCFA when they know the time is honest and free delivery is reachable by grouping purchases.
Can the fee be calculated automatically from the address? Yes, a real online store detects the zone from the entered neighbourhood and applies the fee automatically. This is impossible to keep up manually on a WhatsApp catalogue beyond a few orders a day.
