Supplier Due Diligence Checklist
Use this before payment or onboarding.
First order
A first order creates a small relationship before it creates a large one. The buyer has little history, the supplier has little reason to prioritize the account, and both sides may rush to prove momentum. That is exactly when verification should stay simple and strict.
Many first orders begin with a sales contact, a catalog, and a price that looks workable. Those items help commercial discussion, but they do not identify the counterparty. Ask for the Chinese legal name, business license, unified social credit code, invoice issuer, and bank beneficiary before you argue over the last point of price. A first order does not need a long investigation, but it does need one clean identity file.
Use the Chinese legal name as the anchor. English names shift across websites, trade platforms, email signatures, and product brochures. A supplier may use a brand name for export, a factory nickname in conversation, and a trading company on the invoice. That structure can work. You still need to know which legal entity will take your money and which entity stands behind delivery.
A first order should test the supplier's discipline, not only its product. Watch how the supplier handles documents, payment details, timeline changes, quality questions, and small corrections. A good supplier may be busy, but it can still answer direct questions. A weak supplier may send polished material while avoiding the entity and payment questions that matter.
Set the deposit so a mistake will hurt but not damage the business. Buyers often treat a first order as a shortcut to production, especially when a customer deadline sits behind it. That pressure rewards the wrong behavior. If a supplier cannot provide a coherent business license, invoice, bank account, and product specification for a first order, it will not become easier after you send money.
The file can be short. Page one names the entity, payee, contact, and product. Page two stores the business license, invoice, bank instruction, and contract draft. Page three lists risk checks: website consistency, payment match, address match, public records, and any mismatch. Page four states the decision: proceed, proceed with a smaller order, request documents, or stop.
The fourth page matters. Procurement teams often collect documents and then skip the conclusion. A folder of files does not tell finance whether to pay. Write the reason in plain language. For example: the supplier exists, the invoice and bank beneficiary match the licensed entity, the website uses the same address, and no unresolved mismatch blocks a small sample order.
A first-order supplier tells you a lot through small behavior. Does the sales contact answer the actual question or send another brochure? Does the supplier explain why the factory name differs from the invoice name? Does the bank account appear early, or does it change after you ask for the proforma invoice? Does the supplier accept a written product specification, or does it keep the order vague?
You do not need to accuse the supplier when answers are weak. Record the weak answer. Ask once more with a specific request. If the supplier still avoids the point, reduce exposure or choose another supplier. A buyer who accepts confusion at the first order usually buys more confusion later.
Approve the first order for the exact product, exact entity, exact payment account, and exact order value reviewed. Do not let that approval become a blanket supplier approval. If the supplier later changes the exporter, raises the deposit, switches the payee, or moves the order to a related factory, reopen the file.
A first order should give the buyer more information than a quotation can. Treat it as a controlled test. If the supplier handles the test with clear documents and steady answers, the next order can carry a deeper relationship. If the supplier resists the basic file, the buyer has learned enough before the larger payment.
It should include legal identity, business license, invoice issuer, bank beneficiary, website consistency, product specification, and a short buyer decision note.
A smaller deposit can reduce exposure while the buyer tests document discipline, delivery behavior, and payment consistency.
Stop or pause when the supplier refuses to identify the legal entity, cannot explain the payee, or changes payment details without a verified reason.
