Part of the IPS series on turning a product idea into a manufactured reality. Start with the complete manufacturing roadmap.

Finding a manufacturer is easy. Type your product into Alibaba and you will have hundreds of options within minutes. Finding a manufacturer who will actually deliver your product to spec, at the agreed price, on time, without cutting corners on materials – that is the hard part.

After 25 years of sourcing factories across China, Vietnam, and Taiwan, we have seen every version of this go wrong. Brands that chose a factory based on a polished website and a low price quote. First-time founders who sent tooling deposits to suppliers they had never verified. Companies that discovered quality problems only after a full container of product had landed at their warehouse.

Start With a Clear Brief – Before You Contact Anyone

The most common mistake brands make when searching for a manufacturer is starting the search before they know what they are looking for. Factories receive hundreds of inquiries. A vague inquiry – “we need someone to make a plastic consumer product, approximately 10,000 units per year” – gets a vague response, or no response at all.

Before reaching out to any manufacturer, have the following ready:

  • Product category and materials: What type of product is it? What materials does it require? Injection-molded plastic, metal components, fabric, electronics?
  • Annual volume estimate: How many units per year are you realistically planning? Be honest – inflating this number to get better pricing will backfire later.
  • Target unit cost: What do you need to land at per unit to make your business model work?
  • Certifications required: Does your product need UL, CE, FCC, CPSC, or other compliance certifications for your target market?
  • Timeline: When do you need first samples? When do you need mass production to begin?

You do not need final CAD files to start sourcing conversations. But you need enough detail that a factory can tell you whether they can actually make your product – and give you a meaningful quote.

Where to Find Manufacturers

Alibaba and Global Sources

These are the obvious starting points, and they are legitimate tools – but they require careful use. The factories that appear at the top of Alibaba search results are not necessarily the best manufacturers. They are the ones that have invested most in their Alibaba presence. Read our detailed guide on the pitfalls of sourcing through Alibaba before you reach out to any supplier there.

When using these platforms, look for suppliers with verified business licenses, substantial transaction history, and audit reports. Filter for “Verified Supplier” status on Alibaba, which requires an independent third-party audit. This is a floor, not a ceiling – it means they passed a basic audit, not that they are the right factory for your product.

Trade Shows

For consumer product brands, the Canton Fair (held twice yearly in Guangzhou, China) is the most comprehensive sourcing event in the world. You can walk the floors, see actual product samples, and meet factory representatives in person. The Hong Kong Electronics Fair is similarly useful for electronics and tech-adjacent products.

Trade shows are time-intensive but valuable for first-time sourcers – seeing a factory’s range of work in person tells you far more than a digital catalog. The downside is that trade show booths often represent trading companies rather than manufacturers, so ask directly: do you manufacture this product yourself, or do you source it from another factory?

Industry Referrals

The best factories are almost never found through a cold search. They are found through referrals from people who have already worked with them. If you have connections in your industry – other founders, product designers, supply chain consultants – asking for factory recommendations is worth far more than hours of Alibaba research.

This is one of the reasons working with an experienced sourcing partner like IPS can compress your timeline significantly. Our factory network has been built and tested over 25 years. We know which factories deliver consistently and which ones look good on paper but fail in practice.

Sourcing Agents

A sourcing agent is an individual or firm with in-country presence in manufacturing regions who can identify, vet, and manage factory relationships on your behalf. Learn more about what a sourcing agent actually does and when you need one. The key is finding an agent who represents your interests – not one who takes commissions from factories for directing business their way.

How to Vet a Factory – The Right Way

Once you have a shortlist of potential manufacturers, the real work begins. This is where most first-time founders cut corners, and where the most costly mistakes happen.

Step 1: Verify They Are Actually a Manufacturer

A significant portion of “manufacturers” on Alibaba and similar platforms are trading companies – middlemen who outsource production to actual factories. This is not always a problem, but you need to know what you are dealing with. Ask directly: do you manufacture this product in-house? If yes, ask to see their production equipment and factory floor – either via a video call walkthrough or photos of the actual facility, not stock images.

Request their business license. In China, a manufacturing company’s business license will list their registered business scope. If the scope does not include manufacturing, they are a trading company.

Step 2: Check Their Experience With Similar Products

A factory that makes excellent plastic housewares may be completely unsuitable for precision electronic components. Ask specifically for samples or photos of products they have manufactured that are similar to yours – in terms of materials, complexity, and production process. Do not accept a general catalog. Ask for specific evidence of relevant experience.

Step 3: Request Client References – and Call Them

Any serious manufacturer should be able to provide references from current or recent clients. Ask for two or three references in your product category and actually contact them. Ask how long they have worked with the factory, whether they have experienced quality or delivery problems, and whether they would use this factory again. Most founders skip this step. The ones who do it consistently make better sourcing decisions.

Step 4: Conduct a Factory Audit

If the factory is in your shortlist for a significant order, conduct an audit before placing it. This can be done in one of three ways:

  • In-person visit: The most thorough option. Walk the production floor, inspect equipment, meet the management team, and see the quality control process firsthand.
  • Video audit: A live video walkthrough conducted with a factory representative. Less thorough than in-person but significantly better than nothing.
  • Third-party audit: Services like QIMA, Bureau Veritas, or SGS conduct standardized factory audits and provide detailed reports. This is the recommended approach when you cannot visit in person.

An audit covers the factory’s production capacity, equipment condition, workforce size, quality management systems, social compliance, and health and safety standards. It will also flag red flags that are not visible from a sales conversation – inconsistent record-keeping, inadequate equipment for your product type, or labor practices that could create compliance problems in your target market.

Step 5: Evaluate Their Communication

How a factory communicates during the inquiry phase tells you a great deal about how they will communicate during production. Are responses timely and specific? Do they ask intelligent questions about your product requirements? Do they flag potential challenges honestly, or do they simply say yes to everything?

A factory that says yes to everything during the sales process is a factory that will struggle to tell you about problems during production. The best manufacturing partners push back when something is unclear or problematic. That friction is a sign of competence, not obstruction.

Step 6: Start Small Before Scaling

No matter how thorough your vetting, the only real proof of a factory’s capability is a completed order. For your first production run with any new manufacturer, start with a smaller quantity than you ultimately need. This gives you a real-world test of their quality, communication, and delivery reliability before you commit to larger volumes.

IPS tip: We have seen brands place $200,000 production orders with factories they have never worked with before, based entirely on samples and sales promises. We never recommend this. The cost of a small trial order is almost always worth it.

Red Flags to Watch For

After 25 years of factory sourcing, these are the warning signs that most reliably predict problems:

  • Reluctance to share business license or certifications. Any legitimate manufacturer has these and will provide them on request. Hesitation here is a serious red flag.
  • Prices that seem too good to be true. Dramatic underpricing relative to other quotes almost always means corners will be cut on materials, labor, or quality control.
  • No questions about your product requirements. A factory quoting confidently on a product they know nothing about is not competent – they are telling you what you want to hear.
  • Pressure to skip samples or reduce the sample approval process. Legitimate factories understand why samples matter. Pressure to bypass this step is a sign they know the samples would not pass.
  • Vague answers about their production capacity. If a factory cannot tell you specifically how many units they can produce per month, or what equipment they use, they may not have the capacity they are claiming.
  • No current client references, or references who do not respond. A factory with satisfied clients can produce references. One that cannot is telling you something.

China, Vietnam, or Taiwan – Which Is Right for Your Product?

The right manufacturing region depends on your product type, volume, quality requirements, and supply chain priorities. Here is a practical breakdown:

China

China remains the most capable and complete manufacturing ecosystem in the world for most consumer product categories. The supplier network is unmatched – you can source almost any component, material, or process within a small geographic radius. Production scale, tooling capability, and infrastructure are all world-class. Read our full analysis of the pros and cons of manufacturing in China.

The considerations: US-China tariffs have increased landed costs for brands importing to the US, and some brands are diversifying away from single-country dependency. China is still the right choice for most products, but it should be a deliberate choice rather than a default.

Vietnam

Vietnam has become the leading alternative to China for labor-intensive manufacturing – apparel, footwear, furniture, and increasingly electronics assembly. Labor costs are lower than China, trade relationships with the US and EU are favorable, and manufacturing quality has improved significantly over the past decade. See our Vietnam product sourcing guide for specifics on what works well there.

The consideration: Vietnam’s supplier ecosystem is less developed than China’s for many product categories. Components often still need to be sourced from China and shipped to Vietnam for assembly, which can offset some of the cost advantage.

Taiwan

Taiwan excels in precision manufacturing, advanced electronics, and high-quality injection-molded components where tight tolerances and engineering quality are non-negotiable. Taiwanese manufacturers tend to be more expensive than mainland Chinese alternatives, but the quality and reliability are often significantly better for complex products. See our Made in Taiwan guide for more detail.

IPS tip: IPS has in-country offices and pre-qualified factory networks in China, Vietnam, and Taiwan. We do not recommend a region because it is cheapest – we match your product to the factory and region best suited to produce it well.

What to Confirm Before Placing Your First Order

Even after thorough vetting, there are specific things to confirm in writing before you place a production order with any factory:

  • Approved sample on file: Your production order should reference a specific, signed-off sample. Every unit produced should match it.
  • Production timeline in writing: Agreed start date, milestone dates, and delivery date – not verbal commitments.
  • Payment terms: Standard terms for a first order are typically 30% deposit, 70% before shipment. Be cautious of factories requiring 100% upfront.
  • Quality standards and inspection rights: Confirm in your purchase order that you have the right to conduct third-party inspections at any stage of production.
  • IP protection: Have a signed Non-Disclosure Agreement in place before sharing any CAD files, designs, or proprietary specifications. See our guide on safeguarding intellectual property with overseas manufacturing partners.
  • Defect and rework terms: What happens if the product does not meet spec? Agree on acceptable defect rates and the factory’s responsibility for rework or replacement before problems arise.

How IPS Approaches Factory Sourcing

At IPS, factory sourcing is Step 3 of our ConceptForge manufacturing process – and it sits downstream of product design and DFM review for a reason. We find the right factory for a specific, engineered product, not a vague brief.

Our sourcing process draws on a pre-qualified global factory network built over 25 years, with in-country offices in the US, Taiwan, China, and Vietnam. We conduct competitive bidding across multiple factories for each project, with quality verification built into the process from the start. We manage the factory relationship directly – our clients do not have to navigate language barriers, time zone differences, or the complexity of Asian business norms on their own.

For brands that want to source independently, the framework in this guide will significantly improve your outcomes. For brands that want an experienced partner managing the process, contact IPS for a free consultation.
