What a Buyer Is Actually Comparing When Your Quote Arrives

September 25, 2026 by The Alu CNC Parts editorial desk / how this is checked

Shops tend to think they lose work on price. Sit on the buyer’s side of a few dozen requests and a different picture shows up: most quotes are eliminated before the number is seriously considered, for reasons that had nothing to do with the rate.

What a buyer is holding

Three quotes on the same drawing, 40% apart, and no obvious reason why. Before comparing anything they have to work out whether all three quoted the same part. Usually they did not.

One assumed 80 mm plate, one assumed 60 mm. One applied a tight general tolerance to every dimension, one tightened only the called out features. One included anodizing, one excluded it and did not say so.

The shop that removes that work for the buyer has an advantage that is very hard to out-price.

Make your assumptions explicit

This is the single highest return change to a quote, and it costs nothing.

Quoted from 60 mm plate, 6061-T651.
General tolerance ISO 2768-m, bores 'A' and 'B' held to
the drawn H7.
Type II clear anodize, 15 um, bores masked.
Dimensional report on first article only.
Lead time 4 weeks including coating.

Five lines. The buyer can now line your quote up against the others and see exactly where a difference comes from. When somebody else is cheaper because they left the anodizing out, your quote is the one that reveals it.

Answer fast, even when the answer is a question

Replying inside 48 hours puts you in most conversations. The shop that responds on day one frequently sets the frame: the buyer reads every later quote against the first one they understood.

A same day email saying “we can quote this, two questions first: is the 0.02 mm on the bore before or after anodizing, and is the 52 mm thickness fixed” does more for your position than a polished quote a week later. It signals that somebody read the drawing.

The questions that win work

Buyers consistently report that the quote which asked something is the one they trusted. Useful questions are specific:

Does this tolerance apply before or after coating? Coating growth eats fits and most drawings do not say which they mean.
Is this dimension fixed, or can it move to the next standard stock size?
Is the flatness callout in the free state or clamped? On a large plate this changes the whole process route.
Do you need material certificates, and traceability, or just the parts?

Each of these can move a price by double digits, and asking demonstrates you understand where the cost sits.

Offer the cheaper version alongside the quote

A quote that says “as drawn, this price” and then “if the corner radii go from 1 mm to 3 mm, this lower price, because we can use a stiffer cutter” does two things at once. It wins the job and it makes you the shop the buyer calls next time.

Very few shops do this. The ones that do stop competing on rate.

What loses work before price is read

A quote with no breakdown on a complex part. A single number on a part with coating, inspection and certs tells the buyer nothing about what is included.

Silence on the things that slip. Outside processing is where lead times fail. A quote that says “4 weeks” without saying whether anodizing is inside that is a quote the buyer cannot plan against.

Quoting something you cannot hold. Taking a job at a tolerance you will miss costs you the customer, the rework and the reputation. Declining with a reason, and offering what you can hold, keeps you on the list for the next one.

No reply. Obvious, and still the most common outcome. A shop that is too busy this month and says so stays on the list. A shop that goes quiet does not.

The part shops underrate

Buyers are not only buying parts. They are buying the absence of problems. Somebody who reads a drawing properly, flags what is ambiguous, quotes what they can actually do and tells you early when something slips is worth paying a premium for, and most buyers know it.

That is the whole competitive position for a shop that does not want to win on rate.

Frequently asked questions

Do buyers just take the lowest number?

Less often than shops assume. A buyer with three quotes usually has three different sets of assumptions to reconcile first, and the shop that made its assumptions explicit is the one they trust. Price matters, but it is compared after the buyer works out which quotes are for the same part.

Is it worth quoting a job I am only 70 percent sure about?

Yes, if you say which 30 percent you are unsure about. A quote with a stated assumption is useful. A quote that quietly guesses and then raises the price later costs you the customer and everything after them.

How fast is fast enough?

Inside 48 hours puts you in the conversation on most small and mid sized work. The shop that replies on day one often sets the terms of the comparison, because the buyer reads everything else against it.
