There are several types of businesses: sole proprietorships, partnerships, corporations, non-profits, limited liability companies (LLCs), cooperatives, and franchises. It is important to understand the different types of businesses because each has a unique legal structure that impacts aspects like ownership, liability, taxes, and regulations. The main types are sole proprietorships, which are owned and operated by one individual; partnerships, which are owned and operated by two or more individuals; and corporations, which are legally recognized entities separate from their owners.
