What you get

Quotes that survive contact with a production floor.

Three files for every quoted part. Not just a price — the full reasoning, the engineering flags, and the routing your shop can run from on day one.

01 · DFM

DFM screening on every feature

Internal corner radii, drilling depth ratios, workholding survivability, part rigidity — every feature classified before routing is written.

  • Cutter / corner / depth math
  • Tap breakage risk flagging
  • EDM routing where milling fails
02 · Routing

Op-by-op routing detail

Programming, setup, and run time for each operation. Workholding strategy named. Tool count, special tooling, programmer notes — written for your machinist to follow.

  • Every feature assigned to an op
  • Spot-check verification list
  • Handoff instructions
03 · Risk

Engineering flags surfaced upfront

Drawing/model conflicts, undimensioned features, distortion risk, GD&T ambiguities — flagged before you commit. Each with a recommended resolution.

  • Severity-scored 1–10
  • Drawing references for each flag
  • Walk-away threshold stated
Sample work

A real quote, end to end.

A hydraulic manifold block quoted for a fictional fluid power customer. What we deliver to you (the shop), and what your customer sees after you rebrand it. Same part, two very different documents.

Your analyst report

What we send you: full DFM analysis, three-tier pricing, six operations of routing detail, risk assessment, four engineering flags with recommendations. Everything you need to confidently price the job — but not what you send to your customer.

Your customer's quote

What your shop would send downstream — under your branding, with your pricing, your terms, your lead time. Clean, professional, no internal analysis exposed. This is the example we built showing what the shop did with our analyst report.

Tailored to your shop

We learn your shop before we quote.

Most quoting services run generic. The same RFQ that's a slam-dunk at one shop loses money at another — different machines, different rates, different vendor relationships, different risk appetite. Before we touch your first RFQ, we capture how your shop actually runs. Then every quote we write is built for the way you actually make money.

01 / CAPABILITIES

What you can actually make

Every machine on your floor — make, travels, axes, spindle specs. Inspection equipment. In-house grinding, EDM, welding. We route to what you own, not to what we assume you own.

02 / PRICING STRUCTURE

How you make money

Hourly rates by process, margin targets by tier, material markup, lot minimums, rush charge schedule. Every dollar on every quote reflects how you price work, not generic shop-rate averages.

03 / VENDOR NETWORK

Your real outside processing

Your heat treaters, coaters, waterjet vendors — with the actual rates and lead times you pay. Outside processing is where 30% of quote variance lives. We use your numbers, not industry averages.

04 / POSITIONING

Where you win — and walk away

Your ideal customer, sweet-spot work, walk-away triggers. We quote toward the tier that wins the right jobs for you and flag the wrong ones before they cost you a quote turnaround.

Stintera shop onboarding form — welcome screen
Shop onboarding

~30 minutes. Once. Web-based.

Eleven sections covering capabilities, pricing structure, vendor relationships, materials, certifications, operational profile, and risk preferences. Progress auto-saves to your browser so you can step away and pick up later. Submits a clean CSV to Daniel that drops straight into the quoting system for your shop. Mutual NDA available on the welcome page before you commit.

No commitment required to review. NDA is mutual and covers everything you share.

How it works

Three steps from RFQ to delivered quote.

You send the RFQ

Day 0

Email STEP files, PDFs, drawings, customer specifications — whatever you have. Include quantity, due date, and any context on stock or outside processing. NDA available if needed.

We quote it

24–48 hours

Full eight-stage pipeline: intake, DFM screening, feature extraction, time and cost estimation, routing, risk assessment, workbook population, package strategy. You get the three files plus a one-paragraph summary of any flagged issues.

You ship it to your customer

Same day

Quote is rebrandable under your shop's name and identity. Edit pricing, add your terms, attach your cover. Your customer sees a quote from your shop — not from us.

Pricing

Two ways to work with us.

Pay per quote when you need overflow capacity. Switch to a retainer when quoting becomes a recurring need. Either way, no hidden fees and no guessing what "complex" means.

01 Pay per quote — Best for occasional overflow or one-off projects.
Per-part pricing
$275 base + Features × rate by complexity

$8
per simple feature
  • Drilled hole, no special tolerance
  • Counterbore, spotface, chamfer
  • Basic pocket or profile cut
  • Face mill, edge break

  • Wire EDM or sinker work
Live Estimator Counts adjust the estimate in real time
Heat-treat distortion analysis (+$50/part) is automatically added when the part requires it. Not a checkbox — if it's needed, it's included.

First quote free. New shops get the first part quoted at no charge to evaluate fit. Minimum charge $275 per RFQ. Pricing in USD. New customers prepay until established.
02 Retainer — Best for steady quoting volume and predictable monthly cost.
Monthly flat rate · custom to your volume

Capacity on tap. Costs that don't surprise you.

A monthly flat fee that covers a defined quote volume for your shop, sized to your actual RFQ traffic. You get the same eight-stage pipeline and three-file deliverable on every part — just billed predictably instead of per-RFQ. When work surges, you don't get hit with a surprise invoice. When work is slow, you're not paying for capacity you don't use.

  • Defined monthly volume — sized to your historical RFQ traffic, reviewed quarterly
  • Priority turnaround — retainer customers move to the front of the queue, 24-hour standard
  • Same deliverable quality — full DFM screening, routing detail, and engineering flags on every part
  • Dedicated direct line — no general inbox, talk to your estimator
  • Quarterly volume review — adjust the retainer up or down as your business changes
  • No long-term lock-in — 30-day cancellation, no penalty
