How the agent runs it

When a buyer submits a CAD file or part drawing via the AutoSpec portal, the intake agent parses the technical specs and the quoting agent cross-references live supplier pricing via the Xometry API to generate a margin-aware proposal within 90 minutes. If the buyer accepts, the procurement agent places the production order, the logistics agent books freight and generates shipping labels, and the billing agent invoices the client and reconciles payment — all without human involvement from RFQ to delivery confirmation.

Who this is for

This suits an owner with a background in manufacturing, supply chain, or industrial sales who understands how machine shops and procurement desks operate but wants to arbitrage that knowledge without running a physical facility. A former applications engineer, manufacturing sales rep, or operations manager at a contract manufacturer would have the supplier relationships and technical credibility to seed the first client accounts. They do not need to write code — their edge is knowing which tolerances matter and which suppliers are reliable.

Market opportunity

The US contract manufacturing market exceeds $400B annually, yet the RFQ process remains painfully manual — most buyers wait 3–10 business days for quotes from machine shops that still use email and spreadsheets. Platforms like Xometry and Fictiv have proven buyers will pay a premium for speed and reliability, but they are VC-backed platforms, not agile services businesses. A lean agent-operated intermediary can capture the same margin with zero factory overhead and compete on turnaround time and personalized service for mid-market industrial buyers who find large platforms impersonal.

Boss agent: APEX (Autonomous Procurement EXecutive)

APEX monitors every active RFQ and order in the pipeline, enforces margin floors and lead-time promises, escalates anomalies to human review, and sequences agent handoffs to ensure no order stalls between the quoting, procurement, logistics, and billing stages.

  • No quote may be sent to a client with a gross margin below 20% — orders below this threshold are flagged and held for human review before transmission.
  • No production order may be placed with a supplier whose on-time delivery score in the internal scorecard has fallen below 88% in the trailing 30 days.
  • Any CAD file where the intake agent's confidence score on material or tolerance extraction falls below 0.85 is automatically routed to human technical review before quoting proceeds.

The agent team

🤖
INTAKE (Specification Parsing Agent)
Receives uploaded CAD files and part drawings via the client portal, extracts all manufacturing-relevant parameters (material, finish, tolerance, quantity, delivery deadline), assigns a confidence score to each extraction, and hands a structured spec package to APEX for routing.
🤖
QUOTER (Margin-Aware Pricing Agent)
Receives the structured spec package, queries the Xometry API for live supplier pricing across multiple process options, applies the target margin and any client-tier discounts, selects the optimal supplier-process combination, and generates a formatted client-facing quote document ready for delivery.
🤖
PROCURE (Supplier Order Placement Agent)
Upon quote acceptance confirmed via DocuSign, places the production order with the selected Xometry supplier, monitors order confirmation and production status webhooks, and alerts APEX if a supplier fails to confirm within the SLA window so an alternative supplier can be activated.
🤖
DISPATCH (Logistics and Freight Agent)
Coordinates shipping once production is complete by querying Shippo for carrier rate options, booking the optimal freight service, generating shipping labels, updating the client portal with tracking information, and triggering the billing agent upon confirmed shipment.
🤖
LEDGER (Billing and Reconciliation Agent)
Generates and sends client invoices via QuickBooks Online upon shipment, monitors payment status, sends automated net-30 reminders and overdue notices, reconciles incoming payments against open orders, and produces weekly revenue and margin summaries for the human owner's dashboard.
🤖
SCORE (Supplier Performance and Relationship Agent)
Tracks every supplier's on-time delivery rate, defect rate, and quote accuracy across all completed orders, maintains the internal supplier scorecard that APEX enforces, identifies suppliers whose scores are declining and drafts performance alerts, and monitors Xometry's supplier catalog for new process capabilities that could expand AutoSpec's serviceable part types.

Human touchpoints

// the only things that still need you

  • 👤 Technical review of any RFQ where INTAKE's confidence score falls below 0.85 — a human with machining knowledge must validate the spec interpretation before a quote is sent to avoid costly incorrect orders.
  • 👤 Authorization of any single purchase order exceeding $15,000 to a supplier, requiring human approval before PROCURE places the order to manage cash flow and fraud exposure.
  • 👤 Legal signature on new supplier partnership agreements, client master service agreements, and any contractual amendments — DocuSign routes these to the owner but the decision to sign remains human.
  • 👤 Brand-level response to any public complaint, social media dispute, or client escalation that APEX flags as reputationally sensitive, ensuring tone and accountability remain human-controlled.

Monetization

AutoSpec charges a 22–30% margin over supplier cost on every fulfilled order, priced as a seamless per-part or per-order fee visible to the buyer as a single invoice. Volume clients can be offered monthly retainer tiers ($3K–$10K/mo) for guaranteed turnaround SLAs and dedicated capacity.

Key risks

  • Supplier API pricing data may lag real-world material cost spikes (e.g., aluminum tariffs), causing the quoting agent to underprice orders and compress margins before a human notices.
  • CAD file parsing failures on non-standard file formats (e.g., legacy IGES or proprietary STEP variants) could cause the intake agent to misread tolerances, resulting in incorrect parts being ordered and costly rejects.

Getting started

  1. 1
    Obtain Xometry API partner access credentials
    Apply for Xometry's supplier and quoting API program, which gives programmatic access to real-time machining, sheet metal, and 3D printing pricing. This is the core pricing engine the quoting agent depends on, so securing access is the critical path item before any agent build begins.
  2. 2
    Define the initial part-type scope and tolerances
    Narrow AutoSpec's intake to 3–4 manufacturing processes (CNC machining, laser cutting, sheet metal bending, and anodized aluminum finishing) to constrain the parsing logic and reduce edge-case failures during the first 60 days. This reduces the risk of the intake agent misclassifying exotic part geometries.
  3. 3
    Build and test the CAD intake and spec-parsing agent
    Deploy the intake agent on Claude Managed Agents with tools to extract key parameters (material, tolerances, finish, quantity, lead time) from uploaded STEP and DXF files using a combination of Claude's document understanding and a lightweight geometry parser library. Run 50 historical RFQs through it to validate extraction accuracy above 92% before going live.
  4. 4
    Wire quoting, billing, and logistics agents into one workflow
    Connect the quoting agent output to QuickBooks Online for invoice generation, Shippo for freight label creation, and DocuSign for purchase order confirmation — so the full order lifecycle from accepted quote to shipped part runs as a single orchestrated chain with no manual handoffs. Test end-to-end with three pilot clients under a friends-and-family beta.
  5. 5
    Land first five paying clients via direct industrial outreach
    Use the owner's existing manufacturing network or LinkedIn outreach to procurement managers at mid-sized OEMs and contract manufacturers to offer a 'guaranteed quote in 2 hours' pilot program. These first accounts generate real order data that trains the supervisor agent's margin-enforcement rules and surfaces any edge cases in the parsing pipeline before scaling.
