Everything before this is invisible to your customer. This part is not: it is the bit they stand in the road waiting for, and the bit they judge you on. So it is the part with the most machinery behind it.
Everything ready to leave is sorted into one round per rider — one corridor each, balanced across the riders on shift, in the order they should actually be driven. The bench sorts the parcels into a labelled pile per bike, so the rider takes the right ones and knows it.
A stop the plan thinks will arrive after the door shuts is flagged to the dispatcher as a warning, not refused. The plan is a proposal; a person confirms it.
A photograph is taken at every delivery and matched against the position the parcel was meant to reach. If the two disagree, that is on the record rather than in an argument three days later. Where it matters, the customer is given a short code the rider has to be told at the door — so "delivered" means delivered to the right person, not left with whoever answered.
Most deliveries in Accra start from a description, not an address: "the blue gate past the pharmacy". The first time a rider reaches that door the exact spot is confirmed and kept against the phone number — so the second parcel goes straight there, and the fifth needs no phone call.
This is the part that compounds. A courier who has been to a street a hundred times knows it better than one who has not, and the knowledge stays with the business rather than with whichever rider happened to learn it.
Money collected at a door is recorded against the parcel it came from, and what each rider owes is reconciled the same day rather than at the end of the week. A merchant can see what was collected and what has been handed in without waiting for a statement. Customers can also pay before the rider knocks, where mobile money is switched on.
With the real reason, not "other" — which is what decides whether it goes again tomorrow or goes back to you.
Before the rider sets off: come tomorrow, leave it with the gateman, ring first. From the tracking link, no account.
A customer who has the goods and wants them gone asks from the same link, and a rider is sent to collect. Where it is our fault, the journey is on us.
Where you buy a delivery deadline, a missed one is credited without you having to notice it and ask.
A scorecard that says how your deliveries actually went: how many arrived first time, how many were on the promise, how many journeys a parcel takes, what a drop costs you, and how often you have to claim. Where there are too few parcels for a percentage to mean anything, it shows the counts and says how many more it needs — rather than printing a confident number with four deliveries behind it.
The reference is in the message you were sent.
