The verdict in three sentences
Same-day delivery is a powerful conversion lever, with an observed uplift of +6 to +10 % at checkout. But without a clear order cutoff and enough density, it disrupts your runs and blows up costs. The key is to offer it only where it is viable: an owned surcharge of 800 to 1,800 FCFA/parcel, a 2 pm order cutoff for a 5 pm run, and a minimum of 8 parcels per zone to break even.
The cutoff, backbone of same-day
Without an order deadline, same-day becomes unmanageable: a 4:30 pm order forces you to send a rider out for a single parcel. The cutoff solves this by batching the day's orders into one or two planned runs.
| Order window | Cutoff time | Delivery run | Customer promise |
|---|---|---|---|
| Before 11 am | 11:00 | Departs 12:30 | Delivered by 3 pm |
| 11 am-2 pm | 14:00 | Departs 15:30 | Delivered by 6 pm |
| After 2 pm | — | Rolls to next day | Delivered tomorrow AM |
This framing turns a vague promise into a keepable commitment. The on-time rate then sits between 82 and 90 %, versus far lower figures when every order triggers an isolated trip.
Density and surcharge: the double condition
Same-day is profitable only when two conditions hold: a minimum parcel density per zone and a surcharge the customer accepts.
| Parameter | Standard next-day | Same-day |
|---|---|---|
| Surcharge charged | 0 FCFA | 800-1,800 FCFA |
| Minimum density / zone | 3-4 parcels | 8 parcels |
| Conversion uplift | baseline | +6 to +10 % |
| On-time rate | 90-95 % | 82-90 % |
| Delivery window | full day | 3-4 h |
Below 8 parcels per zone, the same-day run costs too much per parcel: you are subsidizing the service. The right move is to open same-day only on dense areas (central business districts, high-density suburbs) and roll diffuse zones into next-day. The 800 to 1,800 FCFA surcharge must cover the dedicated run: the customer who wants their parcel this afternoon accepts paying for it.
Mini case study
Ibrahim runs a spare-parts store in Lagos. He gets 60 orders/day, 24 of them in two central districts. He pilots same-day on those two zones with a 2 pm cutoff and a 1,500 FCFA surcharge.
Of his 24 dense parcels, he batches 16 into same-day (the rest arrive after cutoff, next-day). The dedicated run costs him 22,000 FCFA; the 16 surcharges bring in 24,000 FCFA, or 2,000 FCFA net margin on the run plus the conversion uplift. Applying +8 % conversion on hesitating visitors, he gains about 5 extra orders/day. At a 30,000 FCFA average basket and 20 % margin, that is roughly 30,000 FCFA of extra margin per day, before counting retention.

FAQ
How much does same-day lift conversion?
The observed uplift is +6 to +10 % on delivery-sensitive visitors. The effect is stronger on urgent purchases (parts, gifts, consumables).
What surcharge should I charge for same-day in Lagos?
An order of magnitude of 800 to 1,800 FCFA per parcel covers the dedicated run. It must be shown clearly so it does not surprise at checkout.
What cutoff time should I pick?
A 2 pm cutoff for a 5 pm run is a solid standard: it leaves time to prepare and batch parcels. Any order after that automatically rolls to next-day.
How many parcels per zone to break even?
A minimum density of 8 parcels per zone makes the same-day run profitable. Below that, it is better not to offer the service on that zone.
What about low-density zones?
Roll them into standard next-day. Opening same-day everywhere destroys margin: reserve it for dense areas where the run fills up.
