Free Diesel Mechanic
Service Agreement
One blown turbo claim or a fleet owner 'forgetting' to pay for ten grand in parts will bury your shop in a week. Without a signed contract, you're just a charity with a toolbox waiting to get sued into the stone age.
Pro Contractor Tip
Include a 'Limitation of Liability' clause to ensure you aren't on the hook for a client's lost revenue or 'downtime' while their rig is in the bay.
Why use a written agreement?
Handshake deals are risky. As a Diesel Mechanic, "scope creep" is your biggest enemy. A clear agreement ensures everyone agrees on the deliverables before money changes hands.

Frequently Asked Questions
How do I stop clients from stiffing me on expensive engine parts?
Demand a parts deposit upfront in your contract; never play bank for a client who doesn't have the skin in the game to cover their own hardware.
What happens when the job grows because I found more broken gear inside the block?
Use a 'Hidden Conditions' clause and a formal change order so every extra hour spent on unexpected damage is billed and documented before you turn another wrench.
How do I handle a client blaming me for a separate failure two weeks later?
A clearly defined 'Scope of Work' in your agreement prevents 'while-you-were-at-it' syndrome and proves exactly which components you touched and which you didn't.
