How to Check That a Vietnamese Supplier Is What It Says It Is

September 24, 2026

Verification is not suspicion, it is arithmetic. A day of checking costs a fraction of a tooling deposit, and it removes the failure mode that first-time buyers most often hit: discovering after payment that the company they audited by website is not the company making the goods.

Here is a sequence that fits the effort to the amount at risk.

Step 1: the free checks, in an hour

Match the names. The legal name on the business registration should match the name on the quotation, the proforma invoice and the bank account. Mismatches are common and they are the single strongest early warning.

Check the address. A production address is an industrial area or a park, not an office suite in a city tower. Satellite imagery is enough to tell the difference.

Reverse image search the photographs. Product and factory photographs that appear on other companies’ sites tell you what you are dealing with in about two minutes.

Read the email domain. A company operating a real export business generally has its own domain. It is a weak signal alone and it adds to the picture.

Look for export evidence. Trade data services list shipments by exporter, and even a free lookup can confirm whether a company has shipped to your region and roughly how often.

Step 2: the questions that separate makers from resellers

Ask these directly. The answers matter less than how they are answered.

1. Which processes run inside your building, and which do you subcontract?
2. How many machines of the type my part needs, and what size?
3. Can you show me the machine that would make my part, on a video call?
4. Who would be my day to day contact, and are they in the factory?
5. What is your capacity utilisation now, and where would my order sit?

A real manufacturer answers the first two immediately and is relaxed about the third. A reseller becomes vague, offers a scheduled visit instead, or sends a polished video that is not of the machine you asked about.

None of this makes a reseller dishonest. It makes them a reseller, which you can decide to work with knowingly.

Step 3: the live walk

A short unscripted video call is the highest value free check available.

Ask to see the specific machine, the incoming material area, the rework area and the finished goods store, with you choosing where the camera goes. You are looking for material staged and labelled, work in progress that could be traced back to a batch, and a rework area that exists and is contained.

What you learn is not whether the equipment is impressive. It is whether the place is organised, and whether the person holding the camera is comfortable being asked.

Step 4: pay for a check when the stakes justify it

Above a certain exposure, usually the point where tooling or a first order becomes material to you, buy an independent look.

A third party factory audit in Vietnam is typically priced per man-day and most straightforward audits take one day. Against a tooling deposit it is a rounding error, and it covers the things you cannot check remotely: equipment counts, process control, records and working conditions. See how a factory audit in Vietnam works.

Run it after shortlisting and before any deposit. Earlier is wasted on candidates you will not use, later is money spent on reassurance rather than on a decision.

Step 5: verify the payment path separately

The most expensive failures in international trade are not manufacturing failures, they are payment failures.

Confirm the bank details through a channel you established independently, not from the invoice email alone. Pay only to an account in the company’s legal name, in Vietnam. If bank details change mid-relationship, stop and re-verify by voice with someone you have spoken to before. Email accounts get compromised, and altered payment instructions are the most common fraud in this business.

See payment terms with Vietnamese factories for the structure that limits exposure even when everything is legitimate.

What verification does not cover

A clean verification tells you the company is real and capable today. It does not tell you the goods will be right, which is what inspection is for, and it does not tell you the relationship will survive a problem, which only time tells.

Treat it as removing one category of risk cheaply, then spend your remaining effort on the specification, the golden sample and the inspection standard, which are what actually decide whether the goods you receive are the goods you ordered.

Matching the effort to the exposure

Verification should scale with what is at risk, not be applied uniformly.

Sample order or a few hundred dollars. The free checks are enough. Names matched, address plausible, photographs not stolen.

First production order with no tooling. Free checks plus a live video walk and one export record you can sanity check.

Any order involving tooling, or a first order that matters to your year. Add a third party audit before the deposit, and structure payment so the balance is released against a passed inspection.

Ongoing relationship at volume. Periodic re-checks, because companies change. Equipment is sold, key staff leave, ownership changes, and the factory you audited three years ago may not be the one making your goods today.

The mistake is not under-verifying small orders. It is applying small-order verification to a project with a tooling deposit attached.

Red flags that are worth acting on

None of these prove anything alone. Two or more together are a reason to slow down.

• The legal name, the quotation and the bank account do not all match.
• The bank account is outside Vietnam, or in a personal name.
• Payment details change mid-relationship, communicated only by email.
• A price far below every other quotation, with vague answers when queried.
• Reluctance to show the specific production area, with a scheduled visit offered instead.
• Certificates that cannot be verified with the issuing body, or that cover the wrong scope.
• Pressure to pay quickly to secure a price or a production slot.

The last one is worth naming plainly. Urgency is the standard tool for preventing verification, and a legitimate factory that loses two days to your checks will still be there afterwards.

What good looks like

For balance, the pattern from suppliers that turn out well: registration produced within a day, a relaxed unscripted video walk, plain answers about what is subcontracted, a quotation that separates tooling and states ownership, and no objection to a third party inspection before the balance payment.

None of that is expensive for an honest factory to provide, which is exactly why asking is worth the small awkwardness.

Send your project brief and we will match you with manufacturers we have already checked at this level, with the processes and order size stated before you spend any time.
