Most suppliers describe a purchase as a price, a lead time and a container. Buyers experience it very differently. Based on visits from contractors in Congo, Nigeria, Niger and Senegal over the past year, the same five stages appear in almost every project and the same three stages cause most of the delay.

The First Question

Almost no buyer starts with “how much is a 60W lamp". They start with a road: its width, its length, whether it carries trucks or motorcycles, and whether the grid reaches it. The suppliers who ask those questions first tend to win the order, because they are the only ones treating it as a project rather than a transaction.

Sample Evaluation

This is where trust is built or lost. Buyers open housings, weigh brackets, test brightness side by side and ask what fails first. A catalogue cannot survive this stage; only a real unit and an engineer can.

The Quotation Gap

The most common frustration is not price. It is a quotation that answers a different question: the buyer asks for a lit kilometre with a rainy-season margin, and receives a unit price with no battery derating, no spare parts and no installation assumption. Rebuilding the quote costs a week and often costs the supplier the deal.

Pilot and Installation

Contractors increasingly ask for a pilot road before a full order. This is healthy. It tests the bracket, the crew’s learning curve and the actual dusk-to-dawn behaviour. The projects that skip this stage are the ones that discover a mounting problem at pole two hundred.

After the Container

The order is not finished when the ship leaves. It finishes when the first fault is handled. A supplier who answers a warranty email in two days with a part number is worth more than one who answered the pre-sales email in two hours.

The lesson for buyers is to evaluate the whole journey, not the sample. The lesson for suppliers is that every stage is a sales stage, including the one after payment.
