The verdict in three sentences
The last mile is half the total cost of an e-commerce delivery, and in Nairobi the lack of formal addresses makes it even more expensive. The problem is not the rider: it is ad-hoc dispatch with no zones, no batching, no GPS pin. Structure routes by zone with geolocation pins and you double drops per day while cutting the failure rate by three.
Why does ad-hoc dispatch destroy your margins?
When every order goes out as it lands, the rider zigzags across town, calls the customer to find the house, waits, sets off again. The result: few parcels delivered, lots of fuel burned, and one customer in five not home. Zone batching changes everything: wait for 6 to 8 parcels in the same neighborhood, order them geographically, then send a single 2-hour run.
The geolocation pin (what3words-style or GPS coordinates shared over WhatsApp) removes the time wasted hunting for the address. When 70% of customers share their exact location, the rider only phones as a last resort.
| Metric | Ad-hoc dispatch | Batched zone routing |
|---|---|---|
| Drops per day per rider | 12 | 22 |
| Failed-delivery rate | 18% | 6% |
| Cost per drop (Nairobi, KES) | 250 | 150 |
| Cost per drop (XOF equivalent) | 1,200 | 700 |
| Fuel per run | Baseline | -30% |
| Delivery window | Random | 2h slots |
| Address pin adoption | 20% | 70% |
| SLA met | Rare | Same-day |
Motorbike or van: which vehicle for which zone?
Vehicle choice weighs heavily on cost per drop. The motorbike shines in the dense center and narrow-lane estates; the van pays off once parcels are bulky or the zone is peripheral and spread out.
| Criterion | Motorbike | Van |
|---|---|---|
| Parcels per run | 8 to 12 | 25 to 40 |
| Fuel cost / 100 km | ~KES 900 | ~KES 2,300 |
| Ideal zone | Dense center | Spread-out edges |
| Bulky parcels | No | Yes |
| Cost per drop (dense) | Low | Medium |
| Rainy season | Sensitive | Robust |
The 2026 rule: motorbike for the center and tight windows, van for large peripheral runs and furniture or appliances.
Mini case study
Issa runs logistics for an online store in Nairobi with 2 motorbike riders. On ad-hoc dispatch they deliver 24 parcels a day (12 each) at KES 250 apiece, that is KES 6,000 in cost, with 18% failures to re-deliver. Switching to batched zone routing with GPS pins, they reach 44 parcels a day at KES 150, so KES 6,600 for nearly double the volume, and failures fall to 6%. Over a 26-day month he goes from 624 to 1,144 parcels delivered with almost the same team: cost per delivered parcel drops from KES 305 (failures included) to KES 160. Estimated net monthly saving: well over KES 80,000 (2026 order of magnitude).

FAQ
Do you need expensive software to optimize routes?
No. A zone-batching module built into your store, plus WhatsApp location sharing, is enough to start. What matters is zone and 2-hour slot discipline, not a KES 8,000-a-month tool.
How do you handle the lack of addresses in Nairobi?
The geolocation pin is the answer: at checkout the customer shares their exact location. With 70% adoption you remove most calls and not-found parcels.
Does batching slow delivery for the customer?
A little, but the 2-hour slot still holds same-day. Customers prefer a reliable window over a "sometime today" delivery that fails one time in five.
How many failures are recoverable?
A well-logged failure (customer away, wrong number) can be rescheduled the next morning. Going from 18% to 6% failures mainly means parcels delivered first time, so fuel and time saved.
