Evaluate and onboard CAD Guardian without mixing procurement with employment screening.

CAD Guardian LLC was formed in Delaware on November 7, 2025. CAD Guardian handles CAD, PDM/PLM, drawing, quote/RFQ, and engineering-system work. TSmithCode.ai handles software-first application, modernization, data, integration, and controlled-automation work.

• Legal and remittance documents use CAD Guardian LLC
• CAD Guardian is the engineering-automation practice
• TSmithCode.ai is the software-engineering practice
• Tax, banking, beneficial-owner, and identity-verification data are exchanged through controlled onboarding

Engagements may use a fixed diagnostic, bounded fixed-fee work, time-and-materials delivery, a subcontract work package, or ongoing support. The applicable agreement and statement of work control the commercial relationship.

• Named scope, assumptions, exclusions, deliverables, and acceptance criteria
• Invoice schedule, payment terms, change control, and stop conditions
• Background intellectual property, project work product, licenses, and third-party terms
• Client review, professional responsibility, release authority, and operational ownership
• Confidentiality, data handling, support, maintenance, and termination responsibilities

• Confirm legal name, remit-to instructions, W-9 handling, invoicing contact, and purchase-order requirements
• Review insurance requirements and provide only currently valid evidence
• Confirm confidentiality, security, access, background-check, and records-retention requirements
• Name technical, commercial, acceptance, and escalation owners
• Approve the statement of work, implementation boundary, communication cadence, and change process
• Record registrations or certifications only after status and scope are verified

The final code set depends on the purchased scope. A classification reference does not represent active SAM registration, a contract vehicle, socioeconomic certification, licensing, insurance, clearance, security authorization, or agency approval.
