The verdict in three sentences
Shipping fees are the number one cause of cart abandonment: a surprise cost at the last step scares off the customer, while a too-low cost eats the margin. The solution is a transparent automatic calculation based on zone and weight, with a well-placed free-shipping threshold. A clear rule shown early in the journey raises conversion by around 9 %.
The four billing models
Four approaches coexist in 2026. Each has its use case and margin impact.
| Model | Principle | Advantage | Risk |
|---|---|---|---|
| Flat fee | Fixed price everywhere | Simple, predictable | Loss on far zones |
| Per zone | Price by distance | Fair, protects margin | Must be well communicated |
| Per weight | Price by weight/volume | Fits heavy parcels | Complex to explain |
| Free threshold | Free above an amount | Boosts average basket | Cost absorbed if miscalibrated |
The per-zone model is the most common for West African e-commerce: it protects margin on the outskirts while staying readable.
The zone matrix and the optimal threshold
Here is a typical zone matrix for a dense city in 2026 and the free threshold's impact on the average basket.
| Zone | Example | 2026 fee | Delay |
|---|---|---|---|
| Zone 1 - center | Downtown | 2,000 FCFA | 24 h |
| Zone 2 - near | Inner districts | 2,500 FCFA | 24-48 h |
| Zone 3 - outskirts | Suburbs | 3,500 FCFA | 48 h |
| Zone 4 - greater metro | Far suburbs | 4,500 - 5,000 FCFA | 48-72 h |
| Other regions | Upcountry | quote / pickup | 2-4 d |
| Free threshold | Avg basket before | Avg basket after | Effect |
| None | 20,000 FCFA | 20,000 FCFA | baseline |
| 1x basket (20,000) | 20,000 FCFA | 22,000 FCFA | +10 % |
| 1.5x basket (30,000) | 20,000 FCFA | 26,000 FCFA | +30 %, margin preserved |
| 2x basket (40,000) | 20,000 FCFA | 24,000 FCFA | threshold too high, less effect |
The threshold at 1.5x the average basket is the sweet spot: high enough to drive add-on purchases, low enough to stay reachable.
Mini case study
Aminata sells fine grocery products online, average basket 18,000 FCFA, 500 orders/month. She charges a flat 2,500 FCFA fee but loses money on outskirt deliveries (real cost 4,000 FCFA) and sees 22 % abandonment at the fee step.
She switches to a per-zone rule (2,000 to 5,000 FCFA) shown from the product page, with free shipping above 27,000 FCFA (1.5x basket). Result: abandonment falls to 13 %, conversion gains ~9 %, and the average basket rises to 23,000 FCFA as customers add an item to hit the free threshold. Over 500 orders, delivery margin turns positive again and revenue grows by about 1.2 million FCFA/month thanks to the higher basket.

FAQ
What average shipping fee should I apply in 2026?
Between 2,000 and 5,000 FCFA by zone. Downtown runs around 2,000 FCFA, while outskirts and greater metro climb to 3,500-5,000 FCFA to cover the real cost.
Where should I set the free-shipping threshold?
At about 1.5x your average basket. With an 18,000-20,000 FCFA basket, a 27,000-30,000 FCFA threshold pushes an add-on without you absorbing shipping at a loss.
Per zone or per weight?
Per zone for most e-commerce: it is the most readable and protects margin. Weight only matters for heavy or bulky products (furniture, appliances).
Why show fees early in the journey?
Because a surprise cost at checkout is the top cause of abandonment. Showing fees from the product page or cart gains about 9 % conversion.
Is automatic calculation hard to set up?
No: a zone matrix and a threshold rule plug straight into checkout. The customer sees the cost compute from their address, with no manual step.
