Vetting a new overseas supplier is a sequence of checks, not a gut call. Confirm the legal entity and business licence, work out whether you are talking to a trading company or the factory itself, verify the address against an audit report, and match the bank account to the registered name. Reference-check with other buyers, get a live video walkthrough, order samples, and arrange a third-party or social audit before a large order. Start small. None of this removes risk entirely, which is why the payment structure has to carry the part that vetting cannot.
A new supplier sends a clean quote, a tidy catalogue, and a bank account to wire a deposit to. Everything looks right, and almost nothing in that exchange has been verified. The work of vetting is turning each of those items into something you have checked yourself, before your money is committed rather than after.
Here is a process you can run on a factory you have never traded with. It is ordered roughly the way you would actually do it, from a desk before you have spent anything to the plant floor before you place a large order.
Confirm the legal entity first
Ask for the registered company name and business licence number, then check them against the official register rather than the letterhead. In China that is the National Enterprise Credit Information Publicity System; most exporting countries have an equivalent public registry. You are confirming three things: that the company exists, that it is in good standing, and that its registered scope of business actually covers manufacturing the product you are buying.
The name on the licence is the name that matters for everything downstream. The trading name on the website, the sales contact's email domain, and the account you are asked to pay can all differ from it, and every one of those differences is a question to ask before you go further.
Tell a trading company from a real manufacturer
Plenty of good business runs through trading companies, but you should know which one you are dealing with, because it changes who controls quality and who you can hold to account. A trader books your order and places it with a factory you never see; a manufacturer makes it under the roof you can visit.
The business licence scope is the first tell. So is the answer to a few specific questions: which production processes happen in your building, how many production lines you run, what your monthly capacity is for this exact product. A trading company answers these in generalities. A factory answers in numbers and can show you the line on a call. Neither is disqualifying, but a trader charging a manufacturer's margin while adding a layer between you and the goods is worth knowing about.
Verify the address, the audit report, and the bank details
Three checks that people skip because they feel like paperwork, and each has caught real problems.
- The address. Match the address on the licence to the address on the quote and to a map. A factory registered at a residential apartment, or at an address that resolves to an office tower, is a trading company at best.
- The audit report. If the supplier offers a factory audit report, read who issued it and when. A report from a recognised firm, dated this year, naming the same legal entity, is worth something. A logo pasted into a PDF is not.
- The bank account. The account name has to match the registered company name. A request to pay a personal account, a Hong Kong account for a mainland factory, or a third company entirely is one of the most common fraud patterns there is, and it is sometimes an account takeover rather than the supplier at all.
That last point has a rule attached, because it is where losses cluster. Treat any last-minute change of bank details as suspect by default, even mid-relationship with a supplier you trust. Confirm the new account by calling a number you already had, not one from the email asking for the change. The mechanics of why this works, and the other common patterns, are covered in how to avoid supplier fraud and in the practical steps for how to pay a Chinese supplier safely.
Reference-check and see the line
A supplier that has shipped to buyers like you can usually name a couple. Ask for two references in your own market and actually contact them; ask what went wrong on an order and how it was handled, because every real supply relationship has a story there and a fabricated reference does not.
Then get a live video walkthrough. Not a produced marketing video, a call where someone walks the line with a phone while you ask them to point the camera at the machine running your product, at the warehouse, at today's date on a screen. It takes twenty minutes and it is remarkably hard to fake in real time. Order samples in parallel, and where it matters, order a second set a few weeks later, since the sample a factory hand-finishes for a prospect is not always the one the line produces at volume.
Audit and inspect before the big order
For a first order of any size, put a set of independent eyes between the factory's claims and your money. A third-party pre-shipment inspection checks that what is in the boxes matches the spec and the quantity before the goods ship; what a pre-shipment inspection checks walks through what that report covers and where its limits are. If your buyers or your own standards require it, a social or ethical audit covers labour and safety conditions the product inspection does not touch.
The through-line for all of it is the same: start small. A first order sized so that losing it would be a bad week rather than a bad year is the cheapest due diligence you can buy, and it tells you things no document will, because it shows you how the supplier behaves when there is real money and a real deadline on the table.
Vetting reduces risk, structure carries the rest
Run every check above and you will screen out most bad actors and a lot of well-meaning incompetence. You will not screen out all of it. A real factory can pass an audit and then have a bad run; a supplier can be genuine on order one and cut a corner on order five when your standing order feels safe to them. Verification lowers the odds. It does not settle the account.
That is why the payment structure has to do the work vetting cannot. The stronger backstop is to stop tying money to trust and tie it to evidence instead: commit the whole order up front so the factory can see it is real, then release it in tranches, each one against a document you already agreed to, the signed PO, a passed inspection report, the bill of lading, plus your own approval before each release.
That is what Tranchio does. It gates each release against the agreed evidence and keeps a tamper-evident record of what was approved and when. It is a control-and-record layer, not a bank: the payment itself is executed by a licensed provider, and the supplier is paid each tranche in full, so the structure protects you without costing them anything. That payment execution goes live at launch; no provider is engaged yet and no funds move through the platform today. The fee is 1.5% on a first order and 0.9% once you have run more than US$50,000 through it, paid by the buyer, not the seller. If that is the backstop you want behind your vetting, you can request access.
