How to quote CNC machined parts faster (and more consistently)

Quoting is where a sub-contract shop quietly leaks money in two directions at once. Quote too slowly and you lose the job to whoever replied first — often before you'd even read the drawing properly. Quote too inconsistently and you win the wrong ones: the jobs you happened to underprice. The fix for both is the same thing — a method you run the same way every time. Here's the one we use.

None of this is exotic. It's the discipline of pricing a part the same way whether it lands at 9am Monday or 5pm Friday, whether you're fresh or it's the eleventh enquiry of the day. Speed and consistency aren't a trade-off; the repeatable method is what gives you both.

The two ways quoting costs you

Too slow. A buyer with a drawing has emailed three shops. The work, more often than not, goes to the one who comes back first with a sensible number. If your quote takes two days because it sits in a pile until someone has a quiet afternoon, you're losing jobs you never even priced.

Too inconsistent. If the price depends on who quoted it and what kind of day they were having, your margin is a lottery. The jobs you win are skewed toward the ones you underpriced; the ones you'd have made good money on, you lost on price. Inconsistent quoting doesn't just cost you on the bad quotes — it selects for them.

We wrote separately about what slow, scattered quoting actually costs. This piece is the other half: the method that fixes it.

A repeatable method, drawing to price

Seven steps. The point isn't that they're clever — it's that you do all seven, in the same order, every time, so nothing gets skipped on a busy day.

1. Read the drawing properly

Before any numbers: material and condition, the tightest tolerances and where they are, surface finish, any critical or inspection-flagged features, the quantity, and the delivery date. The critical features and the quantity are what really move the price — a single ±0.005mm bore changes the whole machining and inspection plan. Five minutes here saves you from re-quoting later.

2. Material

Grade, form (bar, billet, plate), the stock size you'll actually buy, and the offcut or waste you can't avoid. Price it at today's cost, not last year's — material moves, and a quote built on a stale price is a quote that loses money on a metal you forgot had jumped. Note the minimum buy if there is one.

3. Cycle time — the hard part, so standardise it

This is where estimates diverge most between estimators, so it's where consistency pays most. Break it into roughing, finishing and any awkward features, and apply standard rates and assumptions rather than re-deriving from scratch each time. The goal isn't a perfect cycle time — it's the same reasonable cycle time whoever's quoting. A shop that estimates cycle time consistently can be slightly wrong on every job and still be profitable; a shop that estimates it differently every time can't.

4. Setup, fixturing and programming

The one-off costs — setting the job, any fixtures, the programming time — spread across the quantity. This is why one-offs and small batches are expensive per part and why a "can you do 50 instead of 5?" changes the unit price dramatically. Make the amortisation explicit so a quantity change is a number you can re-run, not a re-quote from scratch.

5. Secondary and outsourced operations

Deburring, heat treatment, plating, anodising, grinding, marking — anything after the machining, especially anything you send out. Outsourced finishing carries its own lead time and minimum charge, and forgetting it is one of the most common ways a quote comes in light. Carry the sub-contract lead time through to your delivery promise, too.

6. Inspection

If the job needs a first-article report, a certificate of conformance, or full dimensional inspection, that's real time and it belongs in the price. Shops that quote inspection as "free" are giving away quality-assurance hours they're contractually on the hook for — particularly on aerospace or regulated work.

7. Margin and commercial terms

Apply your margin deliberately, and state your terms — validity period, payment terms, tooling/NRE treatment, what happens to free-issue material. A quote without an expiry is a quote you might have to honour after the material price has moved against you.

Consistency beats speed (but you can have both)

Most shops have an estimator whose pricing lives largely in their head — and they're usually good. The risk isn't that they're wrong; it's that the method walks out the door when they're on holiday, off sick, or retire. The day someone else has to quote, the numbers wobble, and so does the margin. Writing the method down — even on paper — is the first real upgrade. Putting it in a system that applies the same rates and assumptions every time is the second.

Where AI estimating actually fits

This is the part we built DASQuote for, and it's worth being precise about what it does and doesn't do. Give it a STEP file or a PDF drawing and it produces a consistent first-pass estimate — material, a cycle-time breakdown, setup, the lot — in minutes rather than an afternoon. What it removes is the blank page and the day-to-day variance: the same part gets the same starting number every time, regardless of who's quoting or how busy the shop is.

What it doesn't do is replace your judgement. The estimator reviews it, adjusts for the things a model can't see — that this customer always changes the spec, that this finish is a nightmare on this material, that you want this job for strategic reasons — and sends it. It's a fast, consistent floor to build on, not an autopilot. Honest about that, because a shop that trusts a black-box price blindly will get burned, and we'd rather you didn't.
