How to write a sourcing brief a manufacturer can actually quote
Most slow supplier searches are slow because the first message could not be answered. This checklist shows what a manufacturer needs to confirm interest and quote, what can be added later, and how to keep confidential information out of the first round.
The minimum a manufacturer needs
- What it is — product or component, and what it is used for.
- How it is made — process (machining, injection moulding, stamping, moulded rubber, assembly) and material, as far as you know.
- How many — quantity per order and estimated annual volume; say if it is a one-off project or recurring supply.
- What must be true — critical tolerances, surface finish, standards, documentation and any regulatory requirement.
- When — target dates for samples and first delivery.
- Who decides — the person who will evaluate quotations and samples on your side.
What can wait for the second round
Full drawing packages, 3D files, packaging specifications, logistics details and contract terms can follow once a candidate has confirmed interest and basic fit. Sending everything at once to a long list of suppliers wastes their time and exposes your information unnecessarily.
Confidential information
Describe the requirement without confidential drawings in the first message. Agree in writing how documents may be shared — with whom, for what purpose, and whether an NDA is needed — before sending them. If you work through an intermediary, ask them to confirm that your brief will not be forwarded to suppliers without your authorisation.
Ask for a quotation you can compare
- Same drawing revision, material, tolerances, finish and quantities to every candidate.
- One-off costs (tooling, set-up, samples), unit price by quantity band, and freight shown separately.
- Lead time for samples and for series, and the assumptions behind them.
- Documentation included with delivery: material certificates, inspection reports, certificates of conformity where applicable.
- Validity of the quotation and payment terms.
Label what you know
A useful brief separates what is confirmed from what is assumed. The same discipline applies on the supplier side: when answers arrive, record each fact as confirmed, stated by the manufacturer, pending or not available. It keeps the comparison honest and makes the decision meeting shorter.
