Online tune-up parts store

DIY car owners, hobby mechanics and small independent repair shops that want convenient online ordering.

You buy parts at wholesale and sell at a markup. Extra income comes from tune-up kits bundled by vehicle, and repeat orders from shops.

• Knowing car parts or willingness to learn fitment
• Online selling and listings
• Order handling and customer service

• Sales tax registration and resale certificate rules in your state, check with your state revenue department
• Wrong-fit parts mean returns, so use reliable fitment data and a clear returns policy
• Some cleaners and aerosols have shipping restrictions, check carrier rules
• General liability and product liability insurance
• Storing stock at home may need you to check HOA or lease rules

Startup costs are typically around $2,000 to $10,000, depending on your store or marketplace setup and how much stock you buy. A focused range, such as one vehicle make, can help keep early costs down.

Monthly revenue is typically estimated at around $1,000 to $5,000, depending on your range, pricing and how many buyers you reach. Treat this as a rough estimate, not a promise.

Check sales tax registration and resale certificate rules with your state revenue department. Also check carrier restrictions on cleaners and aerosols, consider general liability and product liability insurance, and use reliable fitment data and a clear returns policy.
