There's no single business license
A license is official permission to do a specific type of work; a permit usually authorizes a specific activity, event, or location. What you need depends on your industry, and your city, county, and state — there's no one checklist that covers every business. The only reliable way to know what applies to you is to check with the official agencies for your location and your type of work.
Personal-service examples
Cosmetology and hair braiding licensing rules vary a lot by state — some states require a cosmetology or braiding-specific license, others have exemptions for natural hair braiding, and city rules can add requirements on top of the state's. If you're in Ohio, check the Ohio State Board of Cosmetology's current rules and your city's business licensing office directly rather than relying on general internet advice, since rules do change.
Food examples
Food businesses often have to choose between 'cottage food' rules (which typically allow certain low-risk foods made at home, within limits) and operating from a licensed commercial kitchen, which usually requires health inspections. In Ohio, the Ohio Department of Agriculture and your local health department are the places to check current rules for what you're making and where. Don't assume your product qualifies as cottage food without checking — the allowed food types and sales limits are specific.
Other common categories
Many other activities have their own rules: childcare, pet services, mobile businesses using public space, and events and vendor booths. Keep a private list of what you've checked, which agency confirmed it, the date, and renewal deadlines.
What a vendor's license is
In Ohio, a vendor's license is the state's sales-tax registration for businesses that make retail sales. It is not permission to run a business in general — it is the registration that lets you collect Ohio sales tax on your taxable sales, report those sales, and send the tax to the state. The Ohio Department of Taxation's official vendor's-license page (linked below, and on our Business Registration & Official Resources page) explains the license types, who needs one, and how to apply. Requirements differ by state and locality, so what follows is Ohio-focused, and the official pages are the word to trust.
What it is not: a business license, an EIN, or an LLC
A vendor's license is not a general business license, which a city or county may require before you operate. It is not an EIN, which is a free federal tax ID number you get directly from the IRS. And it is not an LLC, which is a legal structure you register with the Ohio Secretary of State. You may need several of these at once — each comes from a different office, and each handles a different piece. A vendor's license only handles the sales-tax piece, so it never replaces checking your own industry's and city's rules.
When an Ohio seller may need one
Ohio requires a vendor's license for retail sales made as a business. A regular county license covers sales from a fixed place of business — which includes sales made online or by catalog from that location. A transient license covers sellers with no fixed location, like a table at a pop-up market or event. Two everyday examples: a person reselling thrifted vintage dolls online as a regular business, and a person selling handmade goods at a weekend market table. Selling a few of your own used personal items now and then is treated differently — Ohio calls those 'casual sales' — but steadily selling goods you bought or made to resell is retail selling. If your situation falls between those, the official pages are where to check.
The sales-tax connection
A vendor's license and sales tax go together. On a taxable sale in Ohio, you add sales tax to your customer's total, keep track of what you collected, and periodically send it to the state — it is the customer's tax that you collect and pass along, not extra money for you. That means keeping records of what you sold and the tax you collected, then filing and paying by the state's deadlines. If you buy stock to resell, there are resale-certificate rules so you are not paying sales tax on items you will collect tax on when sold. Our Finances > Tax Overview lesson walks through these ideas in plain language.
A short 'do I need one?' guide
Ask yourself four questions. Will I sell taxable goods or services as a business, rather than clearing out my own used things once in a while? Will I sell to people in Ohio? Is this ongoing? Will I sell from a fixed location, move around, or both? If the answers point to regular retail selling in Ohio, start at the official Ohio Department of Taxation vendor's-license page and check your county auditor's office for the license that fits a fixed location. If you sell outside Ohio or only through an online marketplace, follow that marketplace's official seller instructions, since other states and marketplaces handle tax differently. Never assume one business's registration covers yours.

A real-world example
Two people in the same city might have very different requirements: someone doing hair braiding would check Ohio's cosmetology board rules and city licensing, while someone selling homemade jam at a farmers market would check Ohio Department of Agriculture cottage food rules and the local health department — neither one's checklist works for the other. Selling works the same way: a person reselling thrifted dolls online as a business may need an Ohio vendor's license for sales tax, while a neighbor selling one box of old toys at a yard sale is usually making a casual sale.
Steps to take
- Write down exactly what you'll be doing, where (home, mobile, a rented space), and to whom.
- Look up your state's board or department for your specific industry (for example, cosmetology, food, childcare, trades).
- Check your city and county clerk or licensing office for local requirements.
- If you will make taxable retail sales in Ohio, read the official vendor's-license page and check your county auditor's office for the license that fits how and where you sell.
- If you will buy stock to resell, learn how resale certificates work before you make your first wholesale purchase.
- Keep a private, dated log of what you checked, who confirmed it, and renewal dates.
