Write the specification before the RFQ
Suppliers can only quote what you describe. A specification with dimensions, materials, finishes, acceptance criteria and quantity gets comparable quotes; a description of an idea gets estimates that cannot be compared.
- What the product is and what it must do
- Drawings or models for each part
- Materials, finishes and appearance standards
- First-run quantity and expected annual volume
Split the product into sourceable parts
Most products break into molded or fabricated components, purchased parts, assembly and packaging. Decide which supplier owns integration — otherwise it falls to you by default.
Stage the tooling spend
Prove demand with a low-tooling first run where the process allows, then invest in production tooling with real sales data behind it.
Run a comparable RFQ
Send every supplier the same package and the same questions. Differences in price then mean something, and you can see who understood the part.
What to look for in a supplier
- Experience with products at your stage, not just your process
- Willing to give design-for-manufacture feedback
- Clear about what they do in-house versus subcontract
- Volume range that matches your first run and your target
Certifications buyers often need
- ISO 9001
- Industry registrations if your product is regulated
- Product-specific testing or compliance requirements, identified early
Questions to ask prospective manufacturers
- What would you change about this design to reduce cost?
- What is done in-house, and what is subcontracted?
- What tooling is required, who owns it and what does it cost?
- What is the price at the first run quantity and at target volume?
Frequently asked questions
- Do I need one manufacturer for the whole product?
- Not necessarily. A single integrator simplifies management and usually costs more; separate suppliers cost less and require you to manage the interfaces.
- When should I commit to production tooling?
- Once the design is stable and demand is evidenced. Tooling built around a forecast is the most common avoidable cost in a new product launch.
- How many suppliers should I quote?
- Three to five comparable suppliers is usually enough to see the real range without stretching the schedule.
