Startup costs are typically around $25,000 to $100,000, depending on premises, inventory and equipment. These are estimates. Cash can get tied up in slow-selling stock, so starting with fast-moving products helps.

Monthly revenue is typically around $8,000 to $40,000, depending on sales mix, install volume, opening hours and how many installers you have. Plan for around 40 hours a week at minimum.

Check zoning, local business license and sales tax registration with your city or county and state revenue department. Also check garage liability, general liability and workers' compensation insurance, and whether your state regulates auto repair or installation businesses.
