Quote-to-order automation

Quotes for custom machined parts in 20 minutes instead of 3 days

A job shop quoting 60 to 80 custom parts a week was losing orders to faster competitors. Every RFQ needed an estimator to open the drawing, check material, count operations and price it. We built an AI quoting assistant that reads drawings and specs, drafts the quote, and lets the estimator approve in minutes.

What the client got

0 min

Median time to quote

Down from roughly three working days during busy weeks.

0%

Higher quote win rate

Faster, more consistent pricing won jobs that used to go to quicker competitors.

Quotes per estimator per week

The same three estimators handle double the RFQ volume without overtime.

The bottlenecks

  1. Bottleneck 1

    Three estimators, three-day backlog

    RFQs arrived as emails with STEP files, PDFs and sometimes photographs of hand sketches. Each took 30 to 90 minutes to price. By the time the quote went out, the buyer had often ordered elsewhere.

  2. Bottleneck 2

    Pricing lived in one person’s head

    Material rates, machine hourly costs and tolerance surcharges were applied from memory. Two estimators could price the same part 20 percent apart.

  3. Bottleneck 3

    Won quotes were retyped into the ERP

    A purchase order meant re-entering the part, quantity, price and routing into the ERP by hand, with the original quote open in another window.

What we built

  1. Step 1

    RFQ intake and extraction

    Inbound RFQ emails are parsed automatically. Attachments are classified, and an LLM extracts part names, quantities, materials, tolerances, finishes and delivery dates from drawings, spec sheets and the email body into a structured request.

  2. Step 2

    Costing engine with explicit rules

    We codified the shop’s pricing logic: material cost by stock size, machine time by feature count and tolerance class, setup and finishing surcharges, volume breaks. Estimators tuned the rules in a spreadsheet the workflow reads at runtime.

  3. Step 3

    Draft quote for approval

    The estimator sees the extracted spec, the drawing, the cost breakdown and a suggested price side by side. One click approves and sends the branded quote; edits are logged to improve the rules.

  4. Step 4

    Order creation on acceptance

    When the customer accepts, the sales order, routing and material requisition are created in the ERP from the quote record. Nothing is retyped.

Questions clients ask about this engagement

Can the AI read hand-drawn sketches?

Partially. Clear sketches with dimensions are extracted with a confidence score; anything below the threshold is routed to an estimator with the fields pre-filled where possible.

Who owns the pricing rules?

The shop does. They live in a spreadsheet the estimators edit; the workflow reads the current version each time it prices a part.

Custom AI operations platform

One AI dashboard for service, support and production

A mid-size manufacturer ran production, field service and customer support on three disconnected systems. We built a single AI dashboard that reads from all three, flags issues before customers call, and drafts the responses the team used to write by hand.

Supplier RFQs and purchase orders without the inbox

Buyers were sending requests for quotation one email at a time, chasing suppliers by phone, and retyping prices into the ERP. We automated the full loop from RFQ to approved purchase order, with AI reading supplier replies in any format.

Predictive maintenance and field service automation

Machine alerts that book the service visit before the line stops

An OEM with 2,000 machines in the field had telemetry it never acted on. Alerts went to a shared inbox, technicians were dispatched reactively, and customers called first. We built a workflow that reads machine data, predicts failures, and schedules the right technician with the right parts before the customer notices.

B2B outbound engine

Opening 14 new OEM accounts for a contract manufacturer in nine months

A contract manufacturer with two anchor customers wanted to diversify into European and North American OEMs. Trade shows produced business cards, not conversations. We built an account-based outbound engine that reached engineering and sourcing leaders with specific, relevant messages and handed sales a calendar of qualified meetings.
