This page provides practical business guidance for overseas AI hardware, robotics, and smart-device teams preparing for Shenzhen supplier discussions. It is not legal advice.
In short
Good RFQs reduce guesswork. Weak RFQs create fake precision: a neat unit price built on unknown volume, incomplete engineering, and silent exclusions.
What makes a quote a placeholder quote
A placeholder quote is an early number that cannot support a decision. It may assume generic materials, optimistic yield, unverified component prices, no fixtures, minimal testing, and a production volume the buyer never stated. It is useful only as a conversation starter.
The danger begins when the team treats that number as a commitment. Deposits, budgets, and launch plans then rest on assumptions that emerge only after DFM, sample failure, or tooling review.
What a serious RFQ should include
Use a cover brief, revision index, scope matrix, quantity scenarios, specifications, drawings, BOM status, quality and test criteria, packaging needs, certification assumptions, desired schedule, and list of buyer-supplied items. Ask for tooling, NRE, unit price, lead time, MOQ, validity, exclusions, and payment milestones separately.
Require suppliers to state their assumed process, material, yield, component source, subcontracted work, and open questions. A quote with visible assumptions is more valuable than an apparently firm number that conceals them.
Separate necessary details from sensitive details
Build the RFQ in layers. A capability package can describe category, process, approximate dimensions, quantities, and required experience. A controlled pricing package can add selected drawings and BOM detail. Deeper engineering files follow when supplier identity, role, and agreements are clearer.
Not every supplier needs the whole system. A mold shop may need enclosure geometry but not firmware. An SMT partner may need manufacturing outputs and programming requirements but not cloud architecture or training data.
Why quote comparison needs aligned assumptions
Normalize currency, Incoterms, tax treatment, shipping point, volumes, tooling life, cavity count, component brands, testing, packaging, scrap, warranty, and engineering scope. Record whether VAT invoices, export handling, or third-party certification support are included.
Then compare capability and risk alongside price: response quality, questions asked, process ownership, traceability, change control, subcontracting, and willingness to identify uncertainty. The cheapest row is not necessarily the lowest-cost path.
When to review the RFQ before outreach
Review before sending when the package includes sensitive native files, the team is unsure which supplier type should receive it, the design is still moving, or the quote will drive a tooling or pilot decision. This is the moment when a small clarification prevents broad confusion.
A readiness review should leave the founder with an RFQ that suppliers can answer, a disclosure sequence the team can follow, and a comparison sheet that exposes differences rather than hiding them.
A practical readiness lens
Across supplier paths, the useful discipline is the same: define the next decision, identify the party responsible for it, release only the information needed to make it, and preserve a record of assumptions, revisions, approvals, and outputs. That structure supports speed because the team knows what may proceed and what needs another gate.
No checklist removes manufacturing uncertainty. The aim is to expose uncertainty early enough to manage it. Product readiness, supplier role, commercial scope, technical disclosure, tooling, and China-side control should be considered together before a fast conversation becomes a hard-to-reverse dependency.
Frequently Asked Questions
What is a placeholder quote?
It is a preliminary price built on broad or unstated assumptions and therefore unsuitable for final supplier or budget decisions.
What should an RFQ package include?
Include scope, revisions, quantities, specifications, drawings, BOM status, testing, quality, packaging, schedule, assumptions, and requested price breakdowns.
Should CAD/BOM be included in the first RFQ?
Only to the extent needed for that supplier and stage. Use staged disclosure and confirm identity and controls before sharing the full package.
Why are Shenzhen quotes so different?
Suppliers may be pricing different processes, parts, volumes, quality levels, engineering work, tooling, and risk allowances.
