Product Specification Sheet & Buying Brief

Turn a product description into requirements that a supplier can check. Keep fixed details separate from preferences and open questions.

Start With The Decision The Supplier Must Make

A photograph helps identify a style. It rarely tells a supplier enough about material, fit or use to confirm that a product is suitable. Add the details that could change the offer.

Mark each requirement as fixed, preferred or still open. A supplier can then explain an exception instead of quoting against an assumption.

Use One Version Across The Conversation

Give the brief a reference such as HANDLE-A and date every change. When a supplier proposes another material or dimension, record the exception and the buyer’s decision. Send the accepted revision with the RFQ and sample request.

A quantity estimate is useful even when it is a range. For a drying machine, include the material and batch weight; for beads, include diameter and hole size. The important fields depend on the product.

What Comes Next

The specification says what you want. The RFQ asks suppliers to price that requirement. Keep the two linked by reference and revision so changes remain visible.
