Here's an unpopular opinion: most buyers do their due diligence at the wrong end of the deal. They research hard while comparing quotes, and then, the moment they're ready to pay a deposit, they stop — right when it matters most. I think the five minutes before the transfer are worth more than the five days of browsing before it.
The short answer: before you wire money to an Alibaba supplier, ask for the business license number, real monthly capacity, a contactable reference, a live video walkthrough, a written remedy if bulk doesn't match the sample, the logic behind the price, and on-platform contract terms. Two or more evasive answers is reason enough to stop.
Pay attention to how the supplier answers, not just what they say. The stories below are illustrative examples of typical industry cases, not accounts of named clients, and the amounts are examples. They are drawn from the kind of cross-border risk our team sees on the ground — from a $14,000 batch of wheels to a $22,000 order of brake calipers. Next to each question: what you can judge yourself, and where an in-person check changes the picture.
Why Ask These Questions Before the Transfer?
Three reasons the minutes before the transfer are worth more than the days of browsing:
- It is where checking pays off most. Most buyers research hard while comparing quotes and then stop right when they are ready to pay the deposit, exactly when it matters most.
- The way they answer is evidence. A supplier with nothing to hide answers a license-number question in the same conversation; hesitation and detours tell you how the rest of the order will feel.
- Several answers cannot be judged from a chat window. Registration, real capacity and whether bulk will match the sealed sample need a record or a visit.
1. "Can I see your business license number?"
Ask directly, in writing, and notice whether they answer in the same conversation or go quiet for hours.
This matters most in categories where the same photos get reused across dozens of storefronts, and wheels are one of the worst.
A typical case: a buyer sourcing 400 sets of aftermarket wheel rims and hub caps for the BYD platform finds a supplier with sharp photos and a $14,000 quote — a 30% deposit, $4,200, due before production starts.
The red flags: asked for a business license, the supplier goes quiet for three days, then sends a blurry photo of a license registered to a different company in a different province. The deposit is to go to a personal account under an employee's name, not the company's registered account.
The outcome: the buyer wires anyway. Replies slow to one line a day around week four and stop at week six, right when the shipment should be ready. The same rim photos later turn up on other storefronts under other company names. Because the deposit went to a personal account instead of through an Alibaba.com order, Trade Assurance does not apply and the money is written off; the deal never got past chat messages (more in what to do after a scam).
The takeaway: a license that doesn't match the company you're paying is a stop sign, not a detail.
Whether they hand it over immediately or start explaining why they "usually don't share that."
Our team runs the number against the government registry and confirms the manufacturing scope during the visit.
2. "What's your monthly production capacity for this exact product?"
Compare the answer with your order size. If your order alone exceeds their stated monthly capacity, something doesn't add up.
The mismatch is easy to miss when the number sounds impressive.
A typical case: a buyer needing 3,000 LED headlight assemblies for the U.S. aftermarket is quoted a capacity of 5,000 units a month by a supplier whose factory photos show one assembly line and what looks like fifteen or twenty workers.
The outcome: production slips twice, blamed first on a holiday, then on a component shortage — which turns out to mean the overflow was quietly subcontracted to an unlisted workshop with no quality control of its own. The shipment arrives with LED drivers failing within 30 days, a color temperature closer to 5000K than the 6000K on the purchase order, and DOT markings that don't match the certification paperwork.
The takeaway: none of that shows up in a capacity number. It shows up in whether the number was physically possible in the first place.
Whether the number is oddly round, or specific enough to sound like it comes from a real production schedule.
We count production lines and workers on the floor to confirm the stated capacity is physically possible.
3. "Who else has ordered this exact product from you in the last 6 months?"
Ask for a reference you can actually contact — not a testimonial screenshot that could belong to anyone.
A screenshot doesn't survive a phone call, which is exactly why suppliers offer them instead of a name.
A typical case: on a $22,000 order for 500 brake caliper sets, the supplier's first response to a reference request is a testimonial graphic with a logo and no company name.
The red flag: pressed again, the supplier offers a 10-day turnaround on custom-machined calipers — a timeline that leaves no room for the heat-treating and hardening steps that keep a caliper from cracking under load. No real contact ever appears.
The outcome: the buyer walks, and later finds a nearly identical listing — same photos, same product codes — under a different company name.
The takeaway: one phone call to a buyer who'd taken delivery would have exposed the 10-day promise as the outlier it was, before any money moved.
Whether they offer a name at all, or pivot to "we have a great reputation" without specifics.

Propose a specific day and time. A vague "sure, anytime" followed by repeated delays is a signal on its own.
How many times the scheduled call gets pushed back, and for what reason.
We show up in person, which no amount of video-call preparation can fully substitute for. If you would rather have someone on our team show you a factory live, see our live video factory verification.
5. "What happens if the sealed sample doesn't match the bulk shipment?"
Get the answer in writing before you pay — not after a mismatch has already shipped.
A sealed sample is only worth what happens after it's approved.
A typical case: a buyer tests and signs off on a suspension bushing sample, then pays 30% down on a 2,000-set order — $2,700 of a $9,000 total — with the balance due before the container ships.
The outcome: bulk production uses a visibly softer rubber compound than the sample, something that doesn't show up on a packing list or in a photo. The bushings start cracking within weeks of installation, reported back by the buyer's own customers. The supplier blames humidity during ocean transit — no rework offer, no partial refund.
The takeaway: a written remedy doesn't prevent a materials swap. It means there's something to hold them to, instead of an argument about the weather.
Whether they offer a concrete remedy (rework, discount, reshipment) or just reassurance.
We inspect bulk production against the sealed sample directly, before it ships — not after.
6. "Is this price negotiable, and why or why not?"
A supplier who can explain their cost structure — materials, labor, MOQ tiers — is more credible than one who simply discounts on request.
This one's on you — no site visit changes what a real cost explanation sounds like versus a blanket "I'll give you a special price."
Nothing, honestly. I'd rather tell you where a visit doesn't add value than sell you one anyway.
7. "Can we put these terms in a written contract on the platform?"
Insist on Alibaba's on-platform order confirmation — not just an agreement reached in chat.
Whether they resist formalizing terms they already agreed to verbally.
Our bilingual team goes through the Chinese contract with you clause by clause, flags the key terms (payment, delivery date, quality standard, liability for breach) and translates the main points. We are not lawyers and do not give legal advice.
Before you hire anyone to check suppliers, see how the main types of provider compare, and what a sample report should contain.
Payment, shipping and paperwork all assume the supplier is real; sourcing support in China is how to check that first.
Summary: Ask Before the Money Moves
One dodged question deserves a follow-up. Two or more, and the pattern is the answer — a supplier with nothing to hide doesn't need five extra messages to confirm a business license number. In my experience, the suppliers worth working with barely notice these questions; they answer and move on. The ones who turn each question into a negotiation are showing you how the rest of the order will feel.
I don't think you need to interrogate every supplier on every order. Spend the five minutes on the ones about to receive real money, before the money moves.
To sum up: ask the seven questions, and treat two or more evasive answers as a reason to stop. If you pay without them, the realistic cost is a deposit sitting with a supplier you could not identify, and a first batch that may not match the sample. A $49 remote check settles the registration questions for you, and our team in Guangzhou can check capacity and the sealed sample in person before your deposit goes out.
I provide supplier verification services, so you should treat my recommendation accordingly.
