You’ve spent hours searching Alibaba and finally found a supplier that seems perfect. Their prices are competitive, the product photos look professional, and they’ve responded quickly to your messages.

But one question keeps nagging at you: Is this actually a factory—or just a middleman?

It’s one of the most common concerns for first-time startup owners, and for good reason. The good news? You don’t have to guess. Here’s how experienced buyers evaluate suppliers before placing an order.

1. Do Your Own Research First

Before sending an inquiry, spend a few minutes reviewing the supplier’s profile. Use 企查查 (Qichacha) — qcckyc.com — to verify the company’s location, owner information, and line of business.

Once that’s settled, look for details such as:

A complete profile doesn’t guarantee reliability, but it’s usually a positive sign that the supplier has invested in presenting their business professionally.

2. Ask About Their Manufacturing Process

A genuine manufacturer should be able to explain exactly how your product is made. Instead of asking “Are you a factory?” try:

Better questions to ask
  • “How is this product manufactured?”
  • “Which production steps are completed in-house?”
  • “Which processes are outsourced?”
  • “How long does production normally take?”

Specific answers often reveal much more than a simple “Yes, we’re a factory.”

3. Don’t Get Right into Business

This sounds weird, but establishing a relationship with your potential supplier is really important. It gives you insight into how they understand your business and how they operate as a team. You don’t want to do business with a team you don’t like or trust.

Hop on a Zoom call with the factory manager and do a quick interview — lighten up the vibe before rolling up your sleeves.

4. Request Factory Photos — and Better Yet, a Video Tour

Professional marketing photos can be misleading. Once you’ve built a little rapport, ask for real facility content. You don’t want the factory to feel burdened before the order comes in, so time this right.

Ask for photos or video of:

A supplier who is comfortable showing their facility generally has nothing to hide.

5. Ask Technical Questions

At this stage, you should already have 3 candidates. In most Chinese factories, sales representatives answer pricing questions — engineers answer manufacturing questions.

Try asking
  • “Which material grade do you recommend?”
  • “What tolerance can you hold?”
  • “What surface finishes are available?”
  • “Which process is more cost-effective?”

Thoughtful, detailed answers indicate strong technical knowledge and close collaboration with production.

6. Request a Prototype Before a Sample, Before Bulk Orders

A prototype helps test concepts, validate functionality, and explore ideas. A sample is a near-finished product ready for mass production. For early development, always go for a prototype first.

Evaluate these factors when you receive it:

It usually takes a few iterations from prototype to sample — especially if you don’t have a detailed product spec sheet yet.

Note: At PromptoGo, we build your product spec sheet before approaching any factory. This alone cuts down iteration cycles significantly.

7. Consider a Third-Party Inspection

For larger orders, an independent quality inspection is often money well spent. An inspection before shipment can verify:

Finding issues before goods leave the factory is far easier — and far less expensive — than discovering them after they arrive.

Final Thoughts

Many buyers assume a “Verified Supplier” badge on Alibaba guarantees quality. It doesn’t. Verification typically confirms that a business exists — it does not guarantee that every product meets your expectations or that every production run will be flawless.

Successful sourcing isn’t about finding the cheapest supplier — it’s about finding the right one. The kind that has your back when capacity increases and urgent response is needed. Luckily, I have a few of them. 🙂

Bottom line

Do your research, build the relationship, ask technical questions, and never skip the prototype stage. Every step you skip early costs more to fix later.
