Most sourcing mistakes are visible before the first deposit clears — if you know where to look. A wrong choice rarely announces itself; it shows up eight weeks later as a missed ship date, a bulk shipment that doesn't match the approved sample, or a factory that stops answering messages once your money has landed. Here is what to actually check, in order, and the specific signs that mean you should walk away.
Start with paperwork, not photos
A slick Instagram feed or a polished factory-tour video tells you nothing about whether the business behind it can deliver. Before any technical conversation, ask for three documents: a business registration certificate, an export licence (or equivalent trading documentation for the country you're buying from), and — if compliance matters to your brand — current certification numbers you can verify independently with the issuing body, not just a PDF logo pasted into a deck. A legitimate manufacturer produces these without hesitation, usually within a day.
Work out who you're actually talking to
Not everyone quoting you owns a factory. Some are trading companies or agents who resell capacity from factories they don't control and may not disclose — which is not automatically a problem, but it changes who is accountable when something goes wrong. Ask directly: "Is this your own factory, or do you subcontract production?" A straight answer, with the factory's name and location, is a good sign. Evasiveness on this single question is one of the most reliable predictors of trouble later.
The five checks before you send a deposit
1. Verify certifications independently
Don't take a certificate image at face value. amfori BSCI, WRAP, OEKO-TEX and GOTS all have online databases or issuing-body contacts where a certificate number can be checked against the holder's registered name and expiry date. This takes ten minutes and eliminates an entire category of fraud.
2. Ask for a factory visit or a recent third-party audit report
If you can't visit in person, ask for a recent BSCI, WRAP or Sedex SMETA audit report, or commission an independent inspection company to visit on your behalf before you commit volume. A manufacturer confident in its operation will not resist this; one that stalls, offers excuses, or insists photos are enough is telling you something.
3. Test response time and technical literacy before you pay anything
Send a real tech pack or reference sample and see what comes back. A capable merchandising team asks specific, informed questions — about fabric composition, construction detail, size grading — within a day or two. A vague costing that ignores half your spec, or one that arrives suspiciously fast without any clarifying questions, both suggest the same problem: nobody technical actually looked at your brief.
4. Sanity-check the payment terms
The standard structure is a deposit — commonly 30–50% — against confirmed order, with the balance due before or against shipping documents. A demand for 100% upfront, especially from a manufacturer you've never worked with and haven't audited, is a disproportionate ask relative to the risk you're taking on.
5. Check the sample-to-bulk track record
A beautiful proto sample means very little on its own — the real test is whether bulk production matches what was approved. Ask for references from existing clients, or for photos of a recent bulk shipment against its approved PP sample. Manufacturers with nothing to show after being asked directly are usually hiding inconsistency, not modesty.
| Check | Why it matters | How to verify |
|---|---|---|
| Business registration & export licence | Confirms a real, legally operating entity | Request documents; cross-check company name against local registries where available |
| Certification numbers | Certificates are the most commonly faked credential in sourcing | Verify directly with amfori, WRAP, OEKO-TEX or GOTS databases |
| Factory ownership | Determines who is actually accountable for your order | Ask directly; request the factory's name, address and photos of the floor |
| Recent audit report | Shows real, current working conditions — not a marketing claim | Request a BSCI/WRAP/SMETA report, or commission an independent inspection |
| Payment structure | 100% upfront disproportionately shifts risk onto you | Expect a deposit (30–50%) with balance against shipment |
| Sample-to-bulk consistency | A great sample with inconsistent bulk is the single most common sourcing failure | Ask for client references or evidence from a recent bulk shipment |
Red flags that should end the conversation
- Refuses a factory visit or a third-party audit, with no reasonable explanation.
- Won't provide business registration or export documentation after being asked directly.
- Quotes a firm price without ever seeing a tech pack, reference sample or spec sheet.
- Demands full payment upfront from a brand-new relationship with no prior track record together.
- Is vague or evasive about whether they own the factory or are reselling someone else's capacity.
- Can't produce a single verifiable compliance certificate despite claiming several.
- Quotes swing wildly between enquiries for the same spec, with no explanation for the variance.
- Uses pressure tactics — artificial urgency, "this price expires today" — on a decision that should be made carefully.

Buying house, factory, or agent — know which one you're vetting
The checks above apply slightly differently depending on who you're talking to. A factory should pass all of them directly. A buying house should be transparent about which factories it uses and be willing to name them — a buying house that won't name its factory network is functioning as an opaque middleman, not a service. An individual agent sits somewhere in between and should be able to point to a specific, verifiable factory relationship rather than a vague claim of "connections."
The sample stage is your real due diligence
Paperwork and audits tell you whether a manufacturer can be trusted in principle. The proto, fit and PP sampling stages tell you whether they can actually execute your product — how they handle a fit correction, how quickly a second round comes back, whether the hand-feel and construction match what was promised. A manufacturer who handles sampling revisions calmly and communicates clearly through two or three rounds is a far better predictor of bulk performance than any single document.
Frequently asked questions
- What is the biggest red flag when choosing a clothing manufacturer?
- Resistance to a factory visit or independent third-party audit. Everything else — paperwork, payment terms, certifications — can usually be clarified in writing, but a manufacturer that won't let anyone verify its actual operation is the clearest single warning sign.
- Should I pay 100% upfront to a new clothing manufacturer?
- No. Standard practice is a deposit of roughly 30–50% against a confirmed order, with the balance due before or against shipping documents. Full payment upfront from an unaudited, first-time relationship disproportionately shifts risk onto you.
- How do I verify a manufacturer's certifications are real?
- Certification bodies — amfori BSCI, WRAP, OEKO-TEX, GOTS — maintain databases or contactable registries. Ask for the certificate number and verify it directly with the issuing body rather than trusting a logo or PDF supplied by the manufacturer.
- What's the difference between a factory, a buying house and an agent?
- A factory manufactures directly and should pass every vetting check itself. A buying house manages sourcing across a network of factories on your behalf and should be transparent about which ones it uses. An agent is an individual intermediary and should point to specific, verifiable factory relationships rather than vague claims.
- How many sample rounds should it take before bulk production?
- Typically three: a proto sample to confirm concept and construction, a fit sample to correct sizing, and a pre-production (PP) sample as the final reference bulk is measured against. A manufacturer that skips stages to move faster is usually trading your quality control for their schedule.
- Is a lower quote always a bad sign?
- Not automatically, but it deserves the same scrutiny as every other claim — ask what's different about their costing (fabric grade, MOQ, payment terms) rather than assuming either fraud or a genuine bargain.
