Finding a manufacturer is less about searching and more about being easy to quote. Suppliers respond quickly to a clear specification and slowly to a vague idea.
This is the sequence I used to take a backyard game from sketch to national distribution, and it works the same way for a consumer product, a tool, a toy or a packaged good.
1. Write a specification before you contact anyone
A one-page spec sheet with a drawing turns a cold enquiry into a real quote. Without it, most factories will not reply at all.
- Dimensions and tolerances, with a simple drawing or 3D file.
- Materials, finish and colour references.
- Target retail price and your target landed cost.
- Expected first order quantity and annual volume.
- Packaging, labelling and any certification your market requires.
2. Decide domestic or overseas
Domestic manufacturing means shorter lead times, simpler communication, easier quality visits and lower shipping risk, usually at a higher unit cost. Overseas manufacturing, most often in Asia, gives lower unit costs and broader tooling capability, with longer lead times, freight cost and more diligence required.
A common middle path is to prototype and test domestically, then move volume production overseas once the design is locked.
3. Build a shortlist of ten suppliers
- Alibaba and Global Sources for overseas factories — filter for verified suppliers and check the product categories they already make.
- ThomasNet, Maker's Row and Kompass for North American and European manufacturers.
- Trade shows in your category, where you can see samples and meet engineers in one day.
- The back of competing products, which often name the manufacturer or the country of origin.
- Referrals from other founders in your category, which are the highest quality lead of all.
4. Send a request for quote that gets answered
Keep it short: who you are, what the product is, the attached spec and drawing, the quantity you want quoted at three tiers, the packaging requirement, and the date you need the quote by.
Ask every supplier for the same four numbers — unit price at each quantity, tooling cost, sample cost and lead time — so replies are comparable.
5. Vet the factory before you commit
- Confirm they make products like yours, not simply that they accept the order.
- Ask for business licence details and check the company name matches the bank account you are asked to pay.
- Request references or existing customers in your market.
- Ask who owns the tooling you pay for — it should be you, in writing.
- Arrange a third-party inspection or factory audit before a first production run.
- Have your NDA and supply terms signed before sharing full drawings.
6. Order samples and pay for the iteration
Expect two or three sample rounds. Comment in writing with photographs and measurements, and approve a physical golden sample that becomes the quality reference for production.
Sample costs are normal and often credited against the first order. Refusing to pay for samples is the fastest way to be deprioritised.
7. Place a controlled first order
- Negotiate the minimum order quantity down for a first run, even at a higher unit price.
- Use staged payments, commonly a deposit with the balance after inspection, rather than paying everything up front.
- Book pre-shipment inspection against the golden sample.
- Agree Incoterms explicitly so you know who pays freight, duty and insurance.
- Build in time — first runs routinely take longer than quoted.
Frequently asked questions
How much does tooling cost for a new product?
It depends entirely on part size and complexity. Simple injection-moulded parts often start in the low thousands, while multi-cavity or large tools cost far more. Always ask for tooling to be quoted separately from unit price.
What is a realistic minimum order quantity?
Many factories quote several thousand units, but a first order can often be negotiated lower at a higher unit price. Ask directly rather than assuming the published figure is fixed.
How do I avoid being copied by a factory?
Sign an NDA and supply agreement, own your tooling in writing, split production across suppliers where practical, and file a patent application before sharing full drawings.
Should I visit the factory in person?
A visit is valuable before a significant order, but a third-party audit and inspection service gives most of the protection at a fraction of the cost.
