Free Heavy Truck Mechanic
Service Agreement
One botched engine rebuild on a handshake deal will bury your shop under a $20,000 parts bill you'll never recover. You're one 'it was working when I dropped it off' lawsuit away from losing every tool you spent twenty years earning.
Pro Contractor Tip
Include a strict 'Mechanic’s Lien' clause to ensure you keep the keys to that rig until the final invoice clears your bank account.
Why use a written agreement?
Handshake deals are risky. As a Heavy Truck Mechanic, "scope creep" is your biggest enemy. A clear agreement ensures everyone agrees on the deliverables before money changes hands.

Frequently Asked Questions
What do I do if the client wants to provide their own cheap parts to save a buck?
Your contract needs to state that you provide zero warranty on labor for customer-supplied parts. This boundary protects your reputation and prevents you from doing the same job twice for free when their junk parts fail.
How do I handle it when I find more broken parts once I've already opened up the casing?
Never touch a secondary repair without a signed Change Order. Having a written agreement that requires authorization for 'Additional Found Defects' ensures you aren't stuck eating the labor costs for work the client claims they didn't ask for.
What if a fleet owner tries to 'Net-90' me on a massive repair bill?
Set clear payment milestones and late fees in the initial agreement. A solid contract turns a 'favor' into a professional obligation, letting them know that your shop isn't a high-interest payday loan center for their trucking business.
