The verdict in three sentences
Grocery e-commerce is won or lost on the cold chain and delivery windows, not on a pretty catalogue. Without cold, perishable loss rates hit 8 to 15 %; with insulated gear and 2-hour windows they fall below 3 %. On a thin grocery margin of 12 to 25 %, cold logistics decide profitability.
Refrigerated windows vs on-demand without cold
Delivering vegetables or fish like a t-shirt is an expensive mistake. Two models compete: on-demand delivery without cold gear (fast but risky) and scheduled refrigerated windows (planned, reliable). The second wins on sensitive products.
| Criterion | On-demand, no cold | Refrigerated windows |
|---|---|---|
| Perishable loss rate | 8-15 % | < 3 % |
| Failed-delivery rate | ~20 % | < 7 % |
| Customer predictability | Low | High (2h window) |
| Route batching | Hard | Optimized |
| Logistics cost per order | Variable, high | Controlled |
| Fit for frozen / fish | No | Yes |
The real cost of the cold chain
Managing cold does not require a refrigerated truck on day one. Basic gear secures a local route, with a 2026 order-of-magnitude as follows.
| Equipment / item | 2026 cost (estimate) | Use |
|---|---|---|
| Reusable insulated bag | 3,000-7,000 FCFA | 1 order |
| Cooler + ice packs (route) | 25,000-60,000 FCFA | 1 rider/day |
| Extra ice packs | 500-1,500 FCFA each | Recharge |
| Control thermometer | 5,000-12,000 FCFA | Traceability |
| Prep in < 90 min | Internal process | Freshness |
| 2h delivery window | Site setting | Failures -20 % to <7 % |
The winning model in Nairobi: order the day before + morning-window delivery, or hyperlocal (< 5 km) in under 2 hours. In both cases, prep happens at the last moment to maximize freshness.
Mini case study
Wanjiru sells fresh-produce baskets in Nairobi (Westlands, Kilimani). She handles 40 orders/day, average basket 18,000 FCFA, gross margin 20 %. Without a cold chain she loses 12 % of products, roughly 86,400 FCFA/day of value (12 % of 720,000 FCFA of goods). She invests in 15 insulated bags (5,000 FCFA = 75,000 FCFA) and 3 coolers (45,000 FCFA), i.e. 120,000 FCFA. Losses fall to 2.5 %, about 18,000 FCFA/day: 68,400 FCFA saved per day. The gear pays back in under 2 days, and 2-hour windows cut failures from 20 % to 6 %, reducing re-deliveries too.

Do I need a refrigerated truck to start?
No. On local routes, an insulated bag (3,000-7,000 FCFA) and a cooler with ice packs (25,000-60,000 FCFA) hold cold for 2 to 4 hours. A refrigerated truck becomes useful at larger scale.
Why do 2-hour windows change everything?
A short window lets the customer be present: failed deliveries drop from about 20 % to under 7 %. Every failure on perishables is a near-total product loss.
How do I handle prep to stay fresh?
Prep within 90 minutes of departure and leave as late as possible. The site can require next-day ordering for a morning slot, which smooths preparation.
What loss rate should I target in 2026?
Under 3 % with a cold chain, versus 8-15 % without. On a 12-25 % margin, cutting losses by 10 points can double net profit.
Should the site manage windows automatically?
Yes: the customer picks an available slot, slot capacity is capped per zone, and the rider gets a batched route. That is what makes cold profitable.
