The verdict in three sentences
A flat delivery rate (the same price everywhere) is a double mistake: you lose money on far zones and overcharge nearby customers who then abandon. Automatic zone- and weight-based calculation at checkout restores margin while keeping conversion. Adding a free-delivery threshold above 25,000 FCFA lifts the average basket by about 22%.
The flat rate costs more than it earns
Accra and its outskirts naturally split into 3 to 5 zones. A single rate ignores this and unbalances every order. Here is a typical zone rate card for 2026.
| Zone | Distance | Recommended rate | Delay |
|---|---|---|---|
| Zone 1 — central Accra | 0-5 km | 1,000 FCFA | 2-4 h |
| Zone 2 — greater Accra | 5-12 km | 1,800 FCFA | 4-8 h |
| Zone 3 — Tema, Kasoa | 12-25 km | 2,800 FCFA | 24 h |
| Zone 4 — Aburi/Nsawam | 25-40 km | 3,500 FCFA | 24-48 h |
| Zone 5 — other cities | 40 km+ | 5,000 FCFA | 48-72 h |
With a flat rate of 2,500 FCFA, you lose 2,500 FCFA of net margin on every zone-5 delivery (real cost 5,000) and you scare off zone-1 customers who know the run is only worth 1,000 FCFA.
Volumetric weight and the free threshold
Price depends not only on distance but also on volumetric weight (a light but bulky box is expensive to carry). The free threshold, meanwhile, is a conversion and basket lever.
| Lever | Measured effect | 2026 order of magnitude |
|---|---|---|
| Zone-based calculation | Restores margin | -25% delivery losses |
| Volumetric weight | Fair billing | (L×W×H)/5000 in kg |
| Free delivery above 25,000 FCFA | Average basket | +22% |
| Showing the threshold in cart | Conversion | +15% |
| 3-5 zone rate card | Customer clarity | Fits one screen |
Showing "Only 4,000 FCFA away from free delivery" in the cart is one of the best triggers for an add-on purchase: the customer adds a product to reach the threshold.

Abena sells clothing in Accra, 400 orders/month, average basket 20,000 FCFA. On a flat 2,500 FCFA rate, her far zones (20% of orders) cost her 5,000 FCFA real: a loss of 2,500 × 80 = 200,000 FCFA/month. Switching to zone-based calculation, she bills the true cost and recovers that margin. Adding free delivery above 25,000 FCFA, her average basket rises to 24,400 FCFA (+22%), i.e. 1,760,000 FCFA of additional monthly revenue on 400 orders.
FAQ
How many zones should I define?
Three to five keep it readable. Too many zones lose the customer and complicate logistics. In Accra, a split of central / greater Accra / outskirts / Aburi / other cities covers most cases.
Does the free-delivery threshold really sell more?
Yes. A well-placed threshold (around 25,000 FCFA) lifts the average basket by about 22% because customers add an item to reach it. The lost delivery revenue is more than offset by the larger basket.
What is volumetric weight?
It's a weight computed from the parcel's volume (length × width × height / 5000), used when the parcel is bulky but light. It avoids underbilling a big box of foam that takes up the courier's whole bike.
Does zone calculation slow down checkout?
No, it's instant: the customer enters their zone or location and the rate appears at once. Good setup even shows the rate before payment, cutting abandonment from surprise fees.
