How to Start an Auto Mechanic Business
From your training and the shop's paperwork to the first repair a customer pays for, in the order you'll need it.
Opening your own repair business means settling your qualifications, the shop's licenses and permits, a tax ID, insurance and a bank account before the first car comes in. Pricing parts and labor on an invoice has a guide of its own, linked below; this page is about getting the business open.
On training, the BLS profile of automotive service technicians and mechanics (In the US, BLS, last modified September 14, 2026) says "Automotive service technicians and mechanics typically complete a program in automotive service technology or a related field. However, some workers enter the occupation with a high school diploma and learn on the job." It adds: "Certification may be required." For air-conditioning work, the same page says "These workers must be trained and certified in handling refrigerants."
A first repair invoice with sample figures: front brake pads at 1 × $85.00, two rotors at 2 × $70.00 = $140.00 and 2 hours of labor at 2 × $95.00 = $190.00 come to $85.00 + $140.00 + $190.00 = $415.00. Use your own figures; these are only an illustration.
Step-by-step startup guide
Follow these steps to launch your auto mechanic business on solid footing.
- 1
Decide what work you'll take on
Choose general repair or a specialty, such as brakes, diagnostics or air conditioning, and whether you'll rent a bay, open a shop or work as a mobile mechanic.
- 2
Check the certifications your work needs
The BLS (In the US, BLS, last modified September 14, 2026) says "Certification may be required." For refrigerant work it says "These workers must be trained and certified in handling refrigerants." Confirm what applies to the jobs you plan to do.
- 3
Sort out licenses, permits and registration
The SBA's launch guide (In the US, SBA, checked October 31, 2026) says "Most small businesses need a combination of licenses and permits from both federal and state agencies." Check your state and city rules for repair shops, and ask about handling used fluids and parts.
- 4
EIN first, then a shop bank account
The SBA (In the US, SBA, checked October 31, 2026) says "Your Employer Identification Number (EIN) is your business’s federal tax ID number." On banking, it says "As soon as you start accepting or spending money as your business, you should open a business bank account."
- 5
Insure the shop and the work
The SBA (In the US, SBA, checked October 31, 2026) says "You also may be legally required to purchase certain types of business insurance." A licensed insurance agent can explain cover for customers' vehicles in your care.
- 6
Write up the first job
Record the parts, the hours and the car's condition on the work order, then turn it into the invoice when the repair is done.
Tips for starting your auto mechanic business
- Keep detailed job records. Among the tasks it lists, the BLS (In the US, BLS, last modified September 14, 2026) includes: "Document repairs and maintenance performed, including parts used, hours worked, and vehicle condition".
- Set aside money for self-employment tax. The IRS (In the US, IRS, last reviewed or updated October 30, 2026) says "The self-employment tax rate is 15.3%."
- Photograph any damage you find and record it on the work order before any work begins.
- Ask your state and city about rules for disposing of used oil, coolant and batteries before you open.

When this isn't for you
If you're joining a dealership or chain shop as a technician, you won't need these business steps; ask your employer which certifications you'll need to hold yourself.
