Stop losing money on
Machinist projects.
Outsourcing a precision job without a signed agreement is a gamble where your client list and your shop's reputation are the stakes. One 'backdoor deal' between your subcontractor and your top client could dismantle years of business growth overnight.
Pro Tip
Always include a 'Paid-When-Paid' clause to ensure you aren't legally obligated to pay the subcontractor out-of-pocket if the end-client defaults or delays payment on the project.
Material Scrap Liability
If a subcontractor ruins a high-value alloy block (like Titanium or Inconel), you may be stuck with the replacement cost if the agreement doesn't define quality standards and liability.
Client Poaching (Backdoor Solicitation)
Subcontractors may attempt to offer a lower rate directly to your end-client once they know the project scope and delivery requirements.
Proprietary Data Leakage
Sharing CAD/CAM files without strict non-disclosure and ownership clauses allows the subcontractor to reuse your optimized toolpaths for other competitors.

What is a Machinist Subcontractor Agreement?
A Machinist Subcontractor Agreement is a legally binding contract between a primary machine shop and an outside operator. It defines the fabrication scope, establishes independent contractor status for tax purposes, prevents the subcontractor from poaching the end-client, and sets clear liability limits for scrapped materials and manufacturing errors.
Quick Summary
This page provides a comprehensive Machinist Subcontractor Agreement Template tailored for the manufacturing sector. It addresses the high-risk areas of precision machining, including material scrap liability, protection of proprietary CAD data, and strict non-solicitation of end-clients. The content emphasizes the legal necessity of maintaining 1099 status while ensuring the primary contractor's cash flow is protected through 'paid-when-paid' clauses. This is an essential toolkit for any machine shop owner looking to scale capacity safely through outsourcing.
Why Machinists need a clear subcontractor agreement
In the machining industry, the stakes of outsourcing go far beyond simple labor. You are often handing over proprietary CAD files, specialized tooling requirements, and direct access to high-value end-client specifications. Without a Machinist-specific Subcontractor Agreement, you risk the 'Independent Contractor' status being challenged by the IRS, leaving you liable for back taxes and benefits. More critically, a general template won't address the specific liabilities of high-precision work—such as who pays for expensive raw material if a subcontractor misses a tolerance or crashes a machine. This document acts as a shield, legally separating your business from the subcontractor's mistakes while locking down your intellectual property and client relationships. It ensures that the subcontractor remains a vendor, not an employee, and strictly forbids them from leveraging your project to steal your client base.
Do you need an invoice or a contract?
Invoices help you get paid, but they do not define scope, revisions, or ownership. For most projects, professionals use both a contract and an invoice to protect their work and cash flow. MicroFreelanceHub bundles both into a single link.
Real-world scenario
Precision Aero Components landed a massive contract for landing gear pins but didn't have the spindle capacity to finish the secondary milling. They hired a freelance machinist to handle the overflow. Mid-project, the freelancer attempted to contact the aerospace firm directly to bypass Precision Aero and take the whole contract. Because Precision Aero had a specialized Machinist Subcontractor Agreement in place, they were able to immediately halt the freelancer’s work, enforce a heavy liquidated damages clause for the breach of non-solicitation, and legally bar the freelancer from the aerospace firm's facility. The agreement didn't just save the project; it saved a $500,000 annual account from being poached by a temporary worker.
🛡️ What this subcontractor agreement covers:
- ✓Technical Scope of Work and Tolerance Requirements
- ✓Paid-When-Paid Payment Schedule
- ✓Non-Solicitation of End-Clients Clause
- ✓Independent Contractor Status (1099) Affirmation
- ✓Intellectual Property and CAD File Ownership
- ✓Indemnification for Scrapped Materials and Tooling
Pricing & Payment Strategy
Standard industry practice for machining subcontracts involves 'Paid-When-Paid' terms, typically Net 15 or Net 30 after the primary contractor receives funds from the end-client. Liability is usually capped at the value of the labor or the cost of the raw materials provided, depending on who supplied the stock. It is critical to specify that the subcontractor is responsible for their own tooling wear and machine maintenance costs unless otherwise negotiated.
Best practices for Machinists
Define 'Acceptable Quality'
Attach the specific blueprint or GD&T requirements as an exhibit to avoid disputes over part rejection.
Verify Insurance Coverage
Require the subcontractor to provide a COI (Certificate of Insurance) to ensure their own errors don't trigger your premiums.
1. Project Scope and Technical Specifications
The Subcontractor agrees to perform the machining services described in the attached Work Order (the 'Project'). All work must adhere strictly to the provided CAD files, blueprints, and Geometric Dimensioning and Tolerancing (GD&T) standards. The Subcontractor is responsible for inspecting parts to ensure they meet specified tolerances before delivery.
2. Subcontractor Duties and Equipment
The Subcontractor shall provide all machinery, tooling, and labor necessary to complete the Project. The Subcontractor warrants that all equipment used is maintained to industry standards and capable of holding the tolerances required. Any deviations from the provided specifications must be approved in writing by the Primary Contractor.
3. Payment Terms (Paid-When-Paid)
Payment for the services rendered shall be made on a 'Paid-When-Paid' basis. The Primary Contractor shall issue payment to the Subcontractor within ten (10) business days of receiving cleared funds from the End-Client. The Subcontractor acknowledges that the Primary Contractor’s receipt of payment from the End-Client is a condition precedent to any obligation to pay the Subcontractor.
4. Non-Solicitation and Non-Compete
During the term of this Agreement and for a period of twenty-four (24) months thereafter, the Subcontractor shall not, directly or indirectly, solicit, contact, or perform services for the End-Client identified in the Work Order without the express written consent of the Primary Contractor. Violation of this clause shall entitle the Primary Contractor to seek injunctive relief and liquidated damages.
5. Independent Contractor Status
The Subcontractor is an independent contractor and not an employee of the Primary Contractor. The Subcontractor is solely responsible for all tax withholdings, social security payments, workers' compensation, and unemployment insurance. The Subcontractor has no authority to bind the Primary Contractor to any third-party agreements.
6. Insurance and Liability
The Subcontractor shall maintain General Liability and Professional Liability insurance. In the event of material scrap due to Subcontractor error, the Subcontractor shall be liable for the cost of replacement raw materials and any expedited shipping fees required to meet the original deadline. Total liability under this agreement shall be limited to the total value of the subcontracted work order.
- All CAD/CAM files remain the exclusive property of the Primary Contractor.
- Subcontractor must provide a signed Inspection Report with each batch of parts.
- Either party may terminate with 7 days written notice if specifications are not met.

Frequently Asked Questions
Can I hold a subcontractor liable if they miss a delivery deadline?
Yes, if the agreement includes a 'Time is of the Essence' clause and specifies liquidated damages or penalties for late delivery that impacts the end-client.
Does this document prevent the subcontractor from being considered an employee?
It strongly supports that status by defining the sub's control over their own methods, tools, and schedule, but you must also ensure your daily operations reflect this independent relationship.
