The verdict in three sentences
A flat shipping fee is a trap: it loses money on far zones and breaks conversion on near ones where the customer finds the price unfair. Zone pricing fixes both, and a well-placed free-shipping threshold lifts average order value by 21%. Show the fee at the cart, not on the final screen, to avoid abandonment.
Why a flat fee destroys margin
Picture a flat KES 300 fee. On a 3 km run in the CBD you keep a comfortable margin; on a 15 km run to Ruaka you lose KES 120-180. Meanwhile the nearby customer finds KES 300 steep for a 10-minute delivery and abandons. A flat fee upsets everyone and quietly eats margin where you can't see it.
| Model | Near zone | Mid zone | Far zone | Net effect |
|---|---|---|---|---|
| Flat KES 300 | margin -, customer leaves | balanced | loss KES 120-180 | bad everywhere |
| 3-tier zone pricing | KES 200, converts | KES 350 | KES 550, profitable | optimized |
Nairobi's three-zone model
Split Nairobi into three rings from your hub. Each ring gets its own fee, set to cover the real cost of the run plus a small margin. Add a weight surcharge for heavy parcels (appliances, bulk packs).
| Zone | Typical areas | Distance | Base fee | Surcharge > 5 kg |
|---|---|---|---|---|
| Zone 1 | CBD, Kilimani, Westlands | 0-5 km | KES 200 | +KES 80 |
| Zone 2 | South B, Buruburu, Lang'ata | 5-10 km | KES 350 | +KES 120 |
| Zone 3 | Ruaka, Rongai, outskirts | 10-18 km | KES 550 | +KES 180 |
| Upcountry | Beyond metro | > 18 km | Courier quote | by weight |
The free-shipping threshold: an AOV lever
Free shipping above a set amount is the single most effective tool to lift the basket. At a KES 4,000 threshold, the customer adds an item to reach free delivery. You absorb the fee but win on the larger basket's product margin.
| Free-ship threshold | AOV before | AOV after | Change |
|---|---|---|---|
| None | KES 2,900 | KES 2,900 | baseline |
| KES 3,500 | KES 2,900 | KES 3,350 | +16% |
| KES 4,000 | KES 2,900 | KES 3,500 | +21% |
| KES 5,500 | KES 2,900 | KES 3,570 | +23% but fewer conversions |
Set the threshold just above your current AOV (here ~KES 3,500-4,000). Too high, it discourages; too low, it drives nothing.

Wanjiru sells specialty groceries online in Nairobi, AOV KES 2,900, 900 orders/month. She moves to zone pricing and sets free shipping at KES 4,000. AOV rises to KES 3,500 (+21%), adding ~KES 540,000 in monthly revenue. On the 55% of orders that hit the threshold, she gives free delivery (avg cost KES 250 x 495 = KES 123,750), but the extra product margin (KES 600 x 900 x 30% ≈ KES 162,000) more than covers it. Net positive of ~KES 38,000/month, before the conversion gain on near zones.
FAQ
Isn't a flat fee simpler for the customer?
Simpler, but costlier for you and often seen as unfair. Zone pricing shows a price that matches each run's reality: the nearby customer pays less and converts better, the far one covers real cost.
Where should I set the free-shipping threshold?
Just above your current AOV. In Nairobi, if you're at KES 2,900, a KES 4,000 threshold nudges an extra item and lifts the basket ~21% without discouraging.
Should I show fees at the cart?
Yes, absolutely. A fee revealed on the final screen is a top cause of abandonment. Show it from the moment of add-to-cart with a per-area estimator.
How do I handle heavy parcels?
Add a weight surcharge (say +KES 80 to 180 above 5 kg) on top of the zone fee. That prevents losing money on appliances or bulky packs.
Does free shipping really make money?
Yes, when the extra basket's product margin beats the cost of free delivery. In the example, +KES 600 of basket at 30% margin covers the waived fee and leaves a net gain.
