Vetting a new supplier: the audit that happens before the deposit

Every supplier sends the same folder: a clean factory photo, a wall of certificates, and a client list with logos you recognise. None of it tells you whether the deposit you are about to send lands with the people who will actually make your product.

Why the photograph proves nothing

A factory photo can be borrowed, and often is. A certificate can be shared between companies that have nothing else in common. A client list is aspirational more often than it is accurate. None of it is verification, it is marketing, and marketing is not what protects a deposit.

The gate tells you the address. It does not tell you who owns the line.

Real verification happens on a call and on a document, not in a PDF someone designed to be shown. It takes under an hour, and it happens before you quote the factory to a client, not after.

The four checks that take under an hour

Business licence first. Ask for it directly. The registered scope states manufacturing or trading in plain terms, and it can be cross-checked against China's national enterprise credit registry in minutes. A legitimate supplier hands it over without a delay.

Product range second. A factory does a narrow range well. A supplier quoting rackets, kitchenware and LED lighting from the same address is a catalogue with a factory's name on it.

Export history third. Ask which countries they currently ship to. A real answer names markets and, often, a buyer they are comfortable naming. A vague answer is the honest one: they do not know, because someone else runs that relationship.

Live video walk fourth. Ask for a camera on the specific line making your category of product, today, not a promotional video shot last year. The reaction to that request is more informative than the footage itself.

The questions that separate a factory from a sales office

Ask something only production would know: the mould cycle time, the resin ratio, who supplies the raw material and whether you can see the purchase invoice. A factory answers in seconds. A trading company has to check and call you back.

Then ask the question that actually matters: if my order exceeds your capacity this month, where does the overflow go. A real factory names a subcontractor, because it happens to them constantly and they have nothing to hide about it. A trader goes quiet, because admitting it means admitting they do not control production at all.

What happens after the audit passes

Passing the audit clears a supplier for a sample order. It does not clear them for a deposit. Those are two different decisions, made at two different points, and collapsing them into one is the single most common mistake we see from importers buying direct for the first time.

We run this exact sequence before we put a factory in front of a client, and the suppliers that fail rarely fail on paper. They fail on the video call, when the camera does not go where they said it would.

What to remember
  • Ask for the business licence and cross-check the registered scope before any other step.
  • A live video call from the specific production line, unscheduled, filters out more suppliers than any certificate.
  • Ask where overflow production goes. A real factory names a subcontractor; a trader goes quiet.
  • The audit clears a supplier for a sample order, not for a deposit. Treat those as two separate decisions.

Frequently asked questions

What is the fastest way to check if a supplier is telling the truth about its factory?

Ask for the business licence and a live video call from the production line, on the spot. A legitimate manufacturer hands over both without hesitation; a trader improvising an answer usually needs to check with the factory first.

How much of the deposit should be paid before the audit is done?

None of it, ideally. A basic verification, the business licence, the product range, and a working video call, should happen before any deposit leaves your account, not after.

What is a red flag during a supplier audit?

A catalogue spanning unrelated categories from the same factory, reluctance to show the production floor, and technical answers that sound rehearsed rather than specific to your product.
