Free Mechanic Invoice Template
By Mario Martell, former Nissan and Subaru technician and founder of Wrench Node. November 11, 2026.
If you work out of a truck, a driveway or a one-bay garage, you don't need a twelve-section shop invoice. You need something that shows the job, the hours, the parts and what's owed, and that looks professional when you hand it over. This is that.
What's on it
- Your name or business, phone, email and license number if your city or state requires one.
- Bill to with a service address line for mobile jobs.
- Vehicle: year, make, model, VIN or plate, mileage.
- Labor table: job, hours, rate, amount.
- Parts table with where you bought each part, which helps when a part fails under warranty.
- Service call or trip fee, supplies and disposal, tax, total, paid and balance due.
- Payment boxes for cash, card, Zelle, Venmo or Cash App, and check.
- Notes: what you found, what you did, what the customer should watch.
Tips for mobile and solo mechanics
- Charge a trip fee. Driving to the job is time you can't bill as labor. Put it on its own line so it doesn't look like padding.
- Write where each part came from. When a part fails in 3 months, you'll know which store to take it back to.
- Get paid before you leave. Write the balance and mark how they paid while you're still there.
- Take a photo of every invoice. Paper gets lost in a truck. A photo is your record for taxes and warranty calls.
- Know your rate. Our labor rate guide has state averages and a way to set your rate from your own costs.

Frequently asked questions
What's the difference between this and the auto repair invoice?
This one is simpler and labor-first, with a service address and a trip fee line for mobile work. The auto repair invoice is for shops with repair order numbers, shop supply fees and more line items.
How do I invoice when the customer brings their own parts?
Bill labor only, write the part on the parts table with no price, and note that customer-supplied parts carry no warranty from you. The template has that line printed at the bottom.
How much should a mobile mechanic charge per hour?
Survey data puts about half of shops between $100 and $149 an hour and a quarter at $150 or more, and mobile heavy-duty repair is often higher. See our labor rate guide for state averages and a simple way to set your own rate.
Do I need to charge sales tax?
Usually on parts, sometimes on labor. It depends on your state. Ask your state's department of revenue, and keep labor and parts on separate lines so the tax is easy to figure.
