BUYING

What a quotation needs in order to be a quotation.

Most machining enquiries stall because the buyer has a part in mind and no specification on paper. This page is the list worth completing before the first message.

The part
A drawing, or at least the features that decide it
The material
Alloy and temper, not "aluminium"
The tolerance
Which dimensions matter and which are clearance
The finish
And whether it is measured before or after coating
The quantity
And the split, because setup cost is divided by the batch
The standard
What the part has to meet, and who confirms it
The inspection
What is measured, by whom, and when
The route
Where it goes and what it has to survive on the way
Why a photograph is not a specification.

A photograph sets a direction. A specification gets a quote. The gap between them is every dimension that was never written down, and each one becomes a question later.

The most useful sentence in an enquiry.

"The feature we are worried about is the bore position, and here is how we will measure it." It tells the supplier where to spend attention, and it is the sentence that most enquiries leave out.

Why written beats verbal.

The expensive conversations in a programme are the ones about what was agreed. A brief that exists only in a meeting leaves every disputed detail open.
