Do you need a license for this?

there is this company operating on the outskirts of the city of cincinnati but within the county attempting to hire people for cold selling of perfumes. well, they make a lot of claims such as paid training but these claims don't pan out. Im trying to press them. Does a company need a license to operate in the state of ohio? this company has it's logo on a door and goes by infinity management....any info would be appreciated
