Stop losing money on
Machinist projects.
Without a rigid service agreement, your machine shop becomes a free R&D department for every client's 'quick' design change. Vague lead times and undefined tolerances are a fast track to lost margins and expensive, unbillable machine downtime.
Pro Tip
Always include a 'Material Price Adjustment' clause that allows you to update quotes automatically if raw metal or hardware costs fluctuate by more than 5% between the time of the quote and the time of the pour.
Uncompensated Setup Time
Clients often expect to pay only for the finished part, ignoring the hours spent on jig creation, tool paths, and machine calibration.
Client-Supplied Material Defects
If a client provides substandard stock that breaks your tooling or ruins a spindle, you could be held responsible for the lost time without a specific indemnity clause.
Tolerance Disputes
Without defined acceptable deviation ranges, a client can reject an entire batch based on subjective 'feel' rather than measurable engineering standards.

What is a Machinist Service Agreement?
A Machinist Service Agreement is a formal contract that defines the scope of machining work, lead times, precision tolerances, and payment terms. It protects the machinist by setting clear boundaries for machine usage, limiting liability for part failure, and ensuring compensation for setup time and material fluctuations.
Quick Summary
This content provides a comprehensive framework for a Machinist Service Agreement, focusing on operational protection and financial stability. It covers essential clauses like Service Level Agreements (SLAs), material cost adjustments, and independent contractor status. By addressing specific machining risks like tooling damage and tolerance disputes, the page helps machinists move from 'handshake deals' to professional, legally-protected contracts that prevent scope creep and ensure machine uptime remains profitable.
Why Machinists need a clear service agreement
For a professional Machinist, time and precision are the primary commodities. Long-term clients often drift toward 'on-demand' expectations, assuming your machines are always available for their emergencies. A Service Agreement creates a vital legal and professional buffer. It defines exactly what constitutes a 'standard' lead time versus an 'expedited' one, and sets clear Service Level Agreements (SLAs) for tolerances and quality control. By formalizing your status as an independent contractor, you protect yourself from labor misclassification and clarify that you are not an employee of the client. Furthermore, in specialized machining—where a single error in a high-stress component can lead to catastrophic failure—having a robust Limitation of Liability clause is not just a preference; it is a business necessity to prevent a single project from bankrupting your entire operation.
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 Mike’s machine shop was nearly crushed when a long-term aerospace client began demanding 24-hour turnarounds on complex titanium components without paying premium rates. Because Mike had a Machinist Service Agreement in place, he was able to point to his SLA clause, which defined 'Standard Turnaround' as 10 business days. The agreement clearly stated that 'Rush Orders' incurred a 50% surcharge on labor. When the client saw the legally binding price of their urgency, they immediately adjusted their planning cycle to fit Mike’s standard schedule. Additionally, when a batch of client-provided aluminum had hidden inclusions that snapped a $400 end mill, the 'Client-Furnished Material' clause in his agreement ensured the client paid for the replacement tool and the machine reset time. The document transformed a chaotic, loss-leading relationship into a structured, profitable partnership.
🛡️ What this service agreement covers:
- ✓Definition of Machining Tolerances and Finish Standards
- ✓Production Schedule and Expedited Fee Tiers
- ✓Material Procurement and Surcharge Terms
- ✓Quality Inspection and Part Acceptance Procedures
- ✓Ownership of Custom Jigs, Fixtures, and CNC Files
- ✓Independent Contractor Status and Tax Indemnification
Pricing & Payment Strategy
Machinist service pricing should typically be structured as a hybrid of a flat setup fee plus an hourly shop rate for production. For ongoing Service Agreements, it is standard practice to require a 50% deposit on material costs upfront. For 'Guaranteed Capacity' retainers, clients should pay a monthly fee to reserve machine time, which is then billed against at a slightly discounted hourly rate, ensuring the shop has consistent cash flow while the client has guaranteed priority in the production queue.
Best practices for Machinists
Establish an Inspection Window
Mandate that clients must inspect and report any non-conforming parts within 5 business days of delivery or they are deemed accepted.
Retain Tooling Ownership
Explicitly state that any custom fixtures or specialized jigs you build remain your property unless the client pays a specific 'Tooling Transfer Fee'.
1. Scope of Services
The Machinist agrees to perform machining, milling, turning, or related fabrication services as specified in individual Work Orders. The Machinist shall perform all work as an Independent Contractor, utilizing their own equipment, tools, and expertise. All work is 'Build-to-Print' based on Client-provided specifications; the Machinist does not provide engineering or design validation unless expressly stated in writing.
2. Service Level Agreement (SLA)
The Machinist guarantees that all parts will meet the tolerances specified in the Client's technical drawings. If no tolerance is specified, standard shop tolerances of +/- 0.005” shall apply. Standard lead times are defined as 10-15 business days from the receipt of both material and final approved drawings. 'Rush Orders' requiring delivery in less than 5 business days shall be subject to an 'Expedite Fee' of 50% of the total labor cost.
3. Client Responsibilities
The Client is responsible for providing accurate, final CAD files and technical drawings. If the Client provides the raw materials ('Client-Furnished Material'), the Client warrants that such material is free from defects and suitable for the requested machining process. The Client shall indemnify the Machinist for any damage to tooling or machinery caused by undisclosed defects or impurities in Client-Furnished Material.
4. Term & Termination
This Agreement shall remain in effect for a period of twelve (12) months or until terminated by either party. Either party may terminate this agreement with thirty (30) days' written notice. In the event of termination, the Client shall be liable for all labor hours performed and all materials purchased or custom tooling created up to the date of termination.
5. Limitation of Liability
The Machinist’s total liability for any claim arising out of this agreement, whether in contract or tort, shall not exceed the total amount paid by the Client for the specific Work Order in question. Under no circumstances shall the Machinist be liable for consequential, incidental, or 'downstream' damages resulting from the failure of a machined part in a larger assembly or application.

Frequently Asked Questions
How do I handle design changes mid-production?
Your agreement should include a 'Change Order' clause stating that any modifications to the original CAD/blueprint after production starts will result in a work stoppage and a new quote for setup and labor.
Who owns the CNC code I write for the client's part?
Unless specifically sold as a deliverable, the agreement should state that the CNC programming and 'means and methods' of production remain the intellectual property of the Machinist.
