Finding and checking suppliers

What to look at on a factory visit.

A visit exists to establish that the company makes the thing, at the scale you need, in a way that will still work in six months. Most of that is visible in an hour to somebody who knows what to look at, and almost none of it is in the presentation they prepared.

The three things that tell you most.

Work in progress on the floor. A producer who makes what they sell has partly finished goods everywhere, in the state you would expect for the process. A trader has a showroom and a warehouse.

The same product in production for somebody else. Seeing your category being made for another customer tells you the capability is routine rather than aspirational, and it is the single most reassuring thing on a visit.

Who answers technical questions. If the owner has to fetch somebody from the floor to answer a question about moisture or glue, that is a good sign. If nobody can answer it, that is the answer.

What to look at, in order.

Walk the process from raw material to packing rather than being shown the highlights. The order matters, because problems compound downstream and you want to see where they start.

  1. 01

    Raw material storage

    How it is kept, whether it is dry, whether there is enough of it for your order. On timber and agricultural goods this is where quality is already decided.

  2. 02

    The process itself

    Machinery, or hands, and whether either is idle. A floor with no work on it during working hours needs an explanation, and there is often a legitimate one.

  3. 03

    Their own quality control

    Is anybody measuring anything? A moisture meter that is used, records that are filled in, a reject pile that exists. Absence of a reject pile is not a good sign.

  4. 04

    Finished goods and packing

    How things are stored while they wait, and how they are packed. A great deal of Indonesian transit damage originates here rather than at sea.

  5. 05

    The people

    How many, whether the numbers match the capacity they claimed, and whether the place looks like people work there every day.

Questions worth asking on the floor.

Ask what they cannot do. A producer who says yes to everything has either not understood or is not answering. The useful reply names a constraint, and knowing the constraint is what lets you design an order around it.

Ask what their last rejection was and why. The answer tells you whether quality problems are discussed or hidden, and a producer who talks openly about a failure is usually the safer one.

Ask to see the paperwork for a shipment that already went to your market. Not a certificate on a wall, an actual file for an actual container. It is the fastest way to establish whether they have done this before.

Questions buyers ask.

Should I announce the visit?

Yes, and give a window rather than a precise day where you can. An unannounced visit to a small Indonesian workshop often finds nobody senior there and teaches you little. What matters is that the date is yours rather than one they proposed a month out.

Do I need an interpreter?

Usually. Export offices work in English and floors generally do not, and the useful conversations are on the floor. Somebody who can ask a machine operator a direct question is worth more on a factory visit than a fluent office contact.

How many factories can I see in a week?

Fewer than you think, particularly across islands. Within one cluster four or five in a week is realistic. That is why a trip is a poor screening tool and a good confirmation tool: screen from your desk and travel to decide.
