Buying a product with your own brand on it is the most common way importers in Africa build a business that is actually theirs rather than a reseller of someone else's. It is also the step where the industry has the most poorly documented practices, and where a buyer's lack of specific questions costs real money.
This is a practical guide, written from the position of a sourcing partner who has watched a lot of first-time importers make these specific mistakes. It is intended to be used as a checklist in the conversation with a supplier, including us.
There are two MOQs, and they are not the same number
This is the single most misunderstood point in the whole process. A factory has a standard-product MOQ and a customisation MOQ, and they can differ by a factor of ten or more.
The standard-product MOQ applies if you buy the product exactly as it exists in the catalogue, perhaps with a different carton. The customisation MOQ applies the moment you change something structural: your logo on the enclosure, a modified front panel, a different terminal configuration, a custom firmware splash screen, a different colour, custom packaging and manuals.
So when a supplier quotes a minimum order quantity, the useful follow-up question is: is that the MOQ for the standard product, or for my customised version, and what is the MOQ for each individual change? A factory that is confident in its quality will break this down without being pushed. A factory that gives you one number and will not separate the components has already told you something about how the rest of the conversation will go.
Get the customisation scope in writing before discussing price
Price conversations before scope is fixed are worthless, because the quote only means something relative to a specific list of changes. Any competent supplier should provide a written customisation matrix covering what can be changed with no engineering work, what requires engineering and possibly new tooling, and what triggers additional certification testing, which is the expensive category.
Once you have that matrix you can decide what is actually worth paying for. Most importers over-customise early, then find that the engineering cost and the extended lead time outlast the benefit they were buying.
The sample is not a formality, it is the contract
Run a pilot order before scaling, and treat the approved sample as a reference specification rather than an approximate idea of the product. The critical discipline is that the sample you approve must be the physical reference for the production run.
Two things go wrong routinely. The first is that the sample is made with better components than the production run, which is a decision rather than an accident, and it is worth asking directly whether the production BOM will be identical to the sample BOM. The second is that approval happens on appearance, and the failure only appears at 60 degrees inside a container.
What to test on a sample, then, is function rather than finish. Run a full charge and discharge cycle with the battery you intend to pair it with. Load test at rated continuous power. Check behaviour during a grid failure if it is a hybrid. And make the monitoring connection on a real mobile network, not on office wifi. Our guide to specifying hybrid inverters covers the parameters that predict field performance.
Ask who owns the certification
This is the question that gets skipped and then becomes expensive. If you private-label a product and the certification is held in the factory's name, that is not automatically a problem, but you need to know the answer, because it determines what happens when you scale and eventually want certification in your own name.
Three questions to ask in writing. Are the existing test reports issued to the factory entity or transferable to mine? If I later need certification in my own name, what does that cost and how long does it take? And who owns the tooling, the drawings, and the firmware source for a customised product?
For lithium products there is a second ownership question that matters enormously, and it is not a certification question at all. A UN38.3 test report is tied to a specific battery model. If you customise the battery configuration, the test report has to match the model on the label or your container is held. Our UN38.3 and MSDS guide covers this in full, and it is the most common cause of the multi-week delays we see at Lagos and Tema.
Separate the lead times
A supplier quoting one lead time is hiding dependencies. Ask separately for sample preparation, engineering review for customisation, production scheduling, tooling, packaging, and certification, then add them up. The most common surprise for first-time importers is not production. It is certification and engineering review sitting outside the schedule everyone assumed.
Get an answer on payment structure at the same time. The normal pattern is a deposit against the order and the balance against inspection or against shipping documents. For a first order with a new supplier we would rather see a smaller order than a larger one with looser terms, and holding part of the balance until inspection passes is a reasonable thing to ask for.
"100 percent tested" is not a specification
Any of the following will be true of a good supplier, and you can ask which apply: incoming component inspection with lot-level traceability, assembly inspection covering PCB workmanship and mechanical connections, functional test across input range and output voltage, load test at continuous and defined surge conditions, protection testing for overload and short circuit, and batch traceability by serial number with a corrective-action process behind it.
Batch traceability is the one that pays off years later. When a field failure happens, the difference between a two-day answer and a six-week investigation is whether the factory can tell you which cell lot went into which unit.
What I would actually negotiate for
If negotiating capital is limited, spend it on these five things. A pilot order before the main order is non-negotiable on a new relationship. Get a written customisation matrix with separated MOQs, because that one document saves more money than any price negotiation will. Hold part of the balance until inspection passes, which ties directly to the pre-shipment inspection discussed in our inspection guide. Require batch traceability by serial number, which costs the supplier very little and is worth a great deal to you later. And settle the spare parts and warranty claim path before you need it, because that is the answer to "what do I tell my customer when one fails".
One thing I would advise against chasing: the lowest unit price. Our guide to the real cost of a cheap inverter covers the arithmetic. Over a five-year horizon, a unit that fails once and gets replaced costs more than the saving, and your customers remember the failure rather than the price.
If you are working through this checklist with a supplier and want a second opinion on whether their answers hold up, send us their quotation and specification. We will tell you straight what is missing and where the real risk sits.
