Score each in writing, and let the total decide, not the price quote. ## The short version - **Verify the factory exists.** Business licenses, video walkthroughs, and third-party audits separate manufacturers from middlemen with catalogs. - **Ask one hard question early.** How a supplier handles "what happens if the batch fails inspection" tells you more than ten smooth emails. - **Inspect the QC system, not the promise.** A real factory can show you inspection records for someone else's order. - **Cheapest quote, highest risk.** A price far under the cluster of quotes is usually missing a cost you will pay later. - **Write the score down.** Vetting by feel selects for charm, and charm ships defects. ## The scorecard Weight the five areas before you talk to anyone. Ours, generalized: | Area | Weight | Evidence that scores well |
| --- | --- | --- | | Identity and legitimacy | 25 | License matching the company name, factory video call, audit report from a recognized inspection firm | | Communication under pressure | 20 | Direct answers to defect and delay scenarios, named contact, response times that survive week three | | Quality system | 25 | Documented inspection steps, tolerance sheets, willingness to accept third-party inspection before balance payment | | Financial stability | 15 | Years operating, export volume, no pressure for unusual payment schedules or personal accounts | | Export experience | 15 | Has shipped your product type to your destination market and knows its labeling and compliance rules | Score candidates out of 100 and rank them. The winner is frequently the second-cheapest quote with the best paperwork, and almost never the cheapest. ## Tips that come from doing this at volume Our sourcing team works from a studio in Guangzhou, and the vetting habits below come from frameworks applied across more than 500 brands rather than from theory: 1. **Ask for a license, then check the name.** The classic tell of a trading company is a license whose registered name and scope do not match the "factory" you are emailing. Trading companies are not always wrong, but you must know which one you have, because it changes who controls quality. 2. **Take the video call on their factory floor.** A supplier who cannot walk you through production on camera either does not control the facility or does not want you seeing it. Both answers are answers. 3. **Pose the failure scenario before the first order.** "If third-party inspection finds 8 percent defects, what happens?" A good factory has a rework procedure and says so. A bad one negotiates the hypothetical. 4. **Check who actually answers in week three.** The sales engineer who wooed you often hands you to an account clerk after the deposit. Ask upfront who owns your order through production, by name. 5. **Never let payment terms drift to personal accounts.** Payments to an account that does not match the company name void most protection you have. This one rule filters out a remarkable share of eventual disasters. 6. **Make third-party inspection a condition, not a request.** Inspection before balance payment, written into the purchase order. Factories that resist it are quoting a price for uninspected goods, which is a different, cheaper product. ## Decide the exit before you enter The most useful vetting habit has nothing to do with the first order: define, in writing, what would make you leave this supplier. Two failed inspections in a row, a missed ship date beyond an agreed buffer, a quality complaint rate above a threshold you set. Suppliers, like products, deserve scale, fix, or kill criteria agreed before emotions and sunk costs accumulate. The same question is worth aiming at any sourcing partner you hire: ask what would make them tell you to drop a factory they recommended. An operator with real standards answers instantly, because the criteria already exist. One who improvises reassurance will keep you attached to a degrading supplier for exactly as long as you keep paying. ## What most agencies will not tell you A sourcing service that earns a percentage of your factory invoice has a structural reason to prefer bigger orders from smoother negotiations, which is not the same interest as yours. And many "vetting" services are relationship brokers: they route clients to factories they already work with, collect from both sides, and call the shortlist research. Neither model is evil, but you should know which one is quoting you. Ask two questions: how the sourcing fee is calculated, and whether anything flows to them from the factory side. Then make the relationship survivable: your molds, your tooling, your supplier contacts documented in your name from day one, so that leaving the service does not mean losing the supply chain. That documented handover is standard in a properly run [Amazon FBA launch](https://flapen.com/amazon-fba-launch), and its absence is the quiet lock-in this industry runs on. ## Related answers - [How to audit a sourcing partner for Amazon sellers](https://flapen.com/blog/how-to-audit-a-sourcing-partner-for-amazon-sellers) - [Risk checklist for new Amazon suppliers](https://flapen.com/blog/risk-checklist-for-new-amazon-suppliers) - [How to find reliable suppliers for Amazon FBA](https://flapen.com/blog/how-to-find-reliable-suppliers-for-amazon-fba) - [Cheap ways to validate samples before ordering](https://flapen.com/blog/cheap-ways-to-validate-samples-before-ordering) - [Amazon seller roadmaps and capital: the complete guide](https://flapen.com/blog/roadmaps-and-capital) To put a Guangzhou-based team and a written scorecard between your deposit and the factory, talk to [Flapen](https://flapen.com/amazon-consulting). ## Keep learning - [Set up your Amazon seller account](https://flapen.com/guides/account-setup) - [Estimate your launch cost](https://flapen.com/tools/launch-cost-calculator) ## **Frequently Asked Questions**How many suppliers should I vet per product?Are trade shows better than online directories for finding factories?What defect rate should I accept in an inspection standard?Is a sourcing agent worth it for a first order?Should I split orders between two suppliers for safety? ## About the Author![Joel Turcotte Gaucher](https://flapen.com/_vercel/image?url=%2Fimages%2Fteam%2Fjoel-turcotte-gaucher-avatar.webp&w=64&q=100) [**Joel Turcotte Gaucher**](https://flapen.com/blog/author/joel-turcotte-gaucher) Founder & CEO at Flapen Joel has spent 10 years in Amazon and ecommerce, running data and technology at BRANDED and Moonshot Brands, two of the largest Amazon aggregators, where he audited and scaled 60+ acquired brands.
