The verdict in three sentences
Last-mile is the cost line that sinks e-commerce margins in dense cities: it often carries 40 to 50 % of logistics cost for just a few kilometers. The three levers that truly pay off are zone-based pricing, route batching and shifting part of the parcels to pickup points. Combined well, they cut cost per delivered parcel by 20 to 25 % while reducing the failure rate.
What a delivery run really costs
Before optimizing, you must measure. Here are 2026 order-of-magnitude figures for a motorbike delivery in a dense urban zone.
| Item | 2026 unit cost (order of magnitude) | Note |
|---|---|---|
| Simple inner-city run | 1,500 - 2,500 FCFA | Central districts |
| Suburban run | 2,500 - 4,000 FCFA | Distance + traffic |
| Fuel per run | 300 - 600 FCFA | Distance-dependent |
| Cost of a failed delivery | 1,500 - 3,000 FCFA | Re-delivery + lost time |
| Average failure rate | 10 - 20 % | Absent customer, vague address |
| Parcels/day per rider | 20 - 35 | Without route optimization |
The most underestimated hidden cost is the failed delivery: each undelivered parcel is re-attempted once or twice, sometimes doubling its real cost.
The optimization levers and their impact
Each lever attacks a different cost line. The table below sums up the 2026 expected gain.
| Lever | Mechanism | Estimated gain | Investment |
|---|---|---|---|
| Zone pricing | Price per zone, not flat | -10 to -15 % losses | Low (software rule) |
| Route batching | Route optimization | +25 % parcels/route | Medium (routing software) |
| Pickup points | Grouped store pickup | -50 % cost/diverted parcel | Medium (partner network) |
| Delivery slots | Customer picks a window | -8 to -12 % failures | Low |
| Pre-delivery confirmation | SMS/WhatsApp before departure | -30 % no-shows | Low |
| Free-shipping threshold | Free above an amount | +average basket | None |
The free-shipping threshold deserves special attention: set around 1.5x the average basket (often 25,000 to 35,000 FCFA), it nudges the customer to add an item to reach it, absorbing part of the delivery cost.
Mini case study
Awa runs a cosmetics shop and ships 600 parcels/month. Without optimization her average cost is 3,200 FCFA/parcel with an 18 % failure rate, i.e. a logistics bill of 1,920,000 FCFA/month.
She adds three things: WhatsApp confirmation before each departure (failures down to 8 %), route batching by zone (+25 % parcels/route), and shifting 30 % of parcels to two partner pickup points at 1,200 FCFA. Her average cost drops to 2,350 FCFA/parcel, i.e. 1,410,000 FCFA/month. Savings: 510,000 FCFA/month, over 6 million FCFA a year, for a software investment of about 250,000 FCFA.

FAQ
Why is last-mile so expensive in dense cities?
Traffic density, non-standardized addresses and failed deliveries inflate the cost. A simple run costs 1,500 to 2,500 FCFA, but each failure adds 1,500 to 3,000 FCFA in re-delivery, and the failure rate reaches 10 to 20 %.
Do pickup points really lower costs?
Yes: a parcel diverted to a pickup point costs 500 to 1,500 FCFA versus 3,000 at home, up to -50 %. With a 90 % pickup rate and a 24-48h delay, it is the best cost/effort lever.
What failure rate is acceptable?
Below 8-10 % you are fine; above 15 % there is a structural problem (addresses, communication). Pre-delivery SMS or WhatsApp confirmation cuts no-shows by 30 %.
Do I need routing software to optimize routes?
From 30-40 parcels/day, yes: smart batching raises parcels per route by around 25 %. Below that, manual organization by zone is often enough.
Where should I set free shipping?
Around 1.5x your average basket. With a 20,000 FCFA basket, a 30,000 FCFA threshold pushes customers to add a product without crushing your margin.
