Most supplier disasters were visible before the deposit — in a license that didn't cover manufacturing, a reference nobody called, a walkthrough that never happened. This article turns supplier verification into a layered process you can run: documents, capability, references, and red flags, scaled to the size of your program. It is for founders and operators about to commit money to a supplier they have only met on a screen.
Verification is a process, not a profile
A supplier profile is marketing. Verification is the set of checks that establishes three separate facts: this company legally exists and does what it claims; this company can produce your product at your quality and volume; and this company has done it for buyers like you. Profiles, however polished, only ever support the first claim. The discipline that matters is refusing to let enthusiasm compress the sequence — checks happen before the deposit, and each layer builds on the last.
Layer 1: Documents — establish who you are dealing with
Document checks cost hours, not money, and they eliminate a large share of bad counterparties. Run them on every supplier, without exception.
- Business license. Obtain the unified social credit code and check it against a registry lookup. Confirm the registered name matches, character for character, the name on the quotation, the bank account and the contract. A mismatch between invoice title and bank account is the classic setup for payment fraud.
- Business scope. The license states registered activities. If you expect factory-level engineering and pricing, the scope should include manufacturing; a scope limited to trading tells you the "factory" is a reseller — sometimes acceptable, but you deserve to know.
- Registered capital and age. Not guarantees of quality, but a company registered last year with minimal capital carries different counterparty risk than one operating for a decade.
- Export record. Ask for evidence of exports to your destination market — bills of lading with details redacted, or customs-record history. A factory that has never shipped to your market will learn customs compliance on your order.
- Certificates. Any certification offered (CE, FCC-related test reports, CPC documentation) should be checked for scope and validity: does the certificate name this company, this product category, and a real testing body? Certificates borrowed from another factory's product are common.
- Bank account. The account name must exactly match the licensed company name. Never pay a personal account or a similarly named company "because accounting is easier this way."
Layer 2: Capability — establish what they can actually make
Documents confirm existence; capability checks confirm production reality. The key question is which processes are in-house and which are outsourced, because outsourced processes are where quality control quietly leaves the building.
- Video or on-site walkthrough. Ask for a live video tour of the production floor, not a promotional video. Watch for the specific machines your product needs — injection molding, SMT lines, sewing lines, whatever your category requires — and ask which steps happen off-site.
- Capacity evidence. How many lines run your product type, what is current utilization, and where does your order sit in the queue? A factory at capacity that says yes anyway is telling you it plans to subcontract.
- Third-party audit. For material programs, an on-site audit by an independent inspector covers equipment, workflow, quality management and working conditions. FULVERA runs audits before first deposits on material programs — see our quality and compliance system for what the audit reports cover.
- Sample depth. A stock sample shows the catalog; a sample made to your brief shows the factory. The second one is the only proof of capability that counts.
Layer 3: References and history — establish how they behave
The first two layers establish that a supplier can; this layer establishes how they act when something goes wrong, which is what you are actually buying.
- Reference calls. Ask for two customers in a market or channel like yours, and actually call them. Three questions do the work: What went wrong in your orders? How did the factory respond? Would you place a first order with them again today?
- Dispute history. Search the supplier's name on the platforms where it sells, including negative reviews and closed accounts. A pattern of vanished accounts under similar names is disqualifying.
- Responsiveness under pressure. How the supplier handles your hardest technical question, your request to change something, or your refusal to accept a first sample tells you how they will handle month three of production.
Red flags that should pause the deal
| Red flag | What it often means | Reasonable response |
|---|---|---|
| Bank account name differs from company name | Payment fraud risk or hidden reseller | Stop until resolved in writing; walk away if excused |
| "Yes" to every requirement instantly | Sales behavior, not engineering review | Put specifics in writing; see which claims survive a spec sheet |
| Certificates that don't name the company or product | Borrowed or falsified test reports | Require original reports from the testing body |
| Refuses any factory visit or live video tour | No factory, or not the factory you think | Treat as a trading company at best; re-price accordingly |
| Price dramatically below all comparable quotes | Different material, different process, or bait | Require a written spec comparison before celebrating |
| Urgency pressure on the deposit | Manufactured scarcity | Hold your sequence; real capacity returns quotes in days, not minutes |
| No export history to your market | Learning curve you will fund | Either price in the risk or choose an experienced exporter |
Match verification depth to program size
Verification costs time and money, so scale it to what you are protecting. The table below is a working default — adjust for category risk (children's products, electricals and food-contact goods deserve the heavier tier at smaller order values).
| Program stage | Typical order value | Minimum verification | Add for high-risk categories |
|---|---|---|---|
| Pilot / test order | Small | Full document layer, live video tour, one reference call | Certificate verification on regulated SKUs |
| First real order | Medium | Document layer plus sample-to-brief proof and third-party pre-shipment inspection | Third-party audit before deposit |
| Core recurring program | Large | On-site audit, DUPRO and pre-shipment inspections each cycle, annual re-verification | Social-compliance audit and batch testing |
You are not verifying that the supplier is good. You are verifying that the claims your order depends on are true.
Verification is also the point where a sourcing partner earns its keep: cluster knowledge finds candidates worth checking, local teams run the walkthroughs and reference calls in the factory's language, and audits arrive as reports you can read rather than impressions you have to trust. If you would rather inherit a verified shortlist than build one, our sourcing program starts from verification and works forward — or send your brief and we will scope the checks your category actually needs.
Frequently asked questions
How do I check a Chinese company's business license?+
Every legally registered Chinese company has a unified social credit code printed on its business license. Request a copy, then check the code against official registry records or third-party business-information databases. Confirm three matches: the registered name against the quotation and bank account, the business scope against the claimed role (manufacturing versus trading), and the registered address against the location the factory claims.
Is a video factory tour enough verification?+
For a small pilot order, a live (not recorded) video tour plus full document checks is a reasonable minimum — ask to see the specific processes your product requires and have the tour guided by production staff, not only sales. For material orders, a video tour is not enough: commission an independent on-site audit, which also reads the factory better than most first-time visitors can.
What is the difference between a factory and a trading company?+
A factory owns production equipment and makes goods; a trading company buys from factories and resells, adding consolidation and export handling. Neither is automatically better — but pricing, engineering access and quality control differ, so you should know which you are talking to. The business license scope, a video tour of the production floor, and direct questions about which processes are in-house will usually settle it.
When should I pay the deposit?+
After the document layer is complete, the account name matches the licensed company, capability is confirmed at the depth your program size warrants, and the contract states the specification, the sealed reference sample, the payment schedule and the inspection rights. If any of those are still open, the deposit is not ready to move.
