The verdict in three sentences
Promising same-day delivery lifts conversion by 15-20 %, but each run costs 1.5 to 2 times a standard delivery. Profitability rests on three settings: an order cut-off at 12pm-2pm, optimized routes of 8 to 12 parcels, and an on-time rate above 92 %. Well calibrated, the ₦1,000-3,000 express surcharge can be billed to the customer without hurting conversion.
Standard, next-day or same-day: the right promise level
Three service levels frame the decision. Standard 2-3 days is cheapest but converts least; planned next-day balances cost and satisfaction; same-day express maximizes conversion but demands tight organization.
| Criterion | Standard 2-3 days | Planned next-day | Same-day express |
|---|---|---|---|
| Conversion lift | Baseline | +8-12 % | +15-20 % |
| Cost vs standard run | 1x | 1.1-1.3x | 1.5-2x |
| Order cut-off | None | Prev. day 6pm | 12pm-2pm |
| On-time target | > 90 % | > 92 % | > 92 % |
| Billable surcharge | ₦0 | ₦500-1,000 | ₦1,000-3,000 |
| Parcels per route | 12-20 | 10-15 | 8-12 |
Same-day reduces parcels per route (tight windows) so unit cost rises. Billing it partly to the customer — ₦1,000 to ₦3,000 — protects margin while keeping the conversion advantage.
The real cost of a same-day run
Break down an express run in an urban zone, average basket ₦25,000.
| Line item | Standard | Same-day |
|---|---|---|
| Base run cost | ₦1,500 | ₦2,700 |
| Parcels per route | 15 | 9 |
| Logistics cost per parcel | ₦100 | ₦300 |
| Surcharge billed to customer | ₦0 | ₦2,000 |
| Net cost borne by the store | ₦1,600 | ₦1,000 |
By charging ₦2,000 for same-day, the store ends up bearing a net cost below standard, while gaining 15-20 % conversion. The key is transparency: the customer pays for the urgency they choose.
Mini case study
Tunde, who runs an electronics store in Lagos, tests same-day with a 1pm cut-off and a ₦2,000 surcharge. On 200 orders/week, 60 pick express. Overall conversion up 16 %. Routes of 9 parcels, on-time rate measured at 93 %. Express revenue: 60 × ₦2,000 = ₦120,000/week, covering the logistics surcharge (60 × ₦1,200 = ₦72,000) and leaving ₦48,000 margin. Bonus: customer reviews mention the speed, feeding repeat purchase.

FAQ
At what volume does same-day pay off?
Once you reach 8 to 12 parcels per route in one zone. Below that, cost per parcel explodes; focus on planned next-day instead.
What cut-off should I set?
Between 12pm and 2pm to leave time to prepare and batch afternoon routes. A late cut-off destroys on-time performance and therefore the promise.
Should I bill for same-day?
Yes, ₦1,000 to ₦3,000. Customers accept paying for the urgency they choose, and it protects your margin without cancelling the conversion gain.
How do I hold an on-time rate above 92 %?
Limited delivery zones, routes of 8-12 parcels max, "rider on the way" notifications and real-time tracking. On-time delivery is what turns a promise into a reputation.
In-house or 3PL for express?
In-house if you master a dense zone; 3PL (Glovo, Yango) to absorb peaks. Many combine: in-house fleet for the city core, 3PL for overflow.
