In AP Business, a sole proprietorship is the simplest type of business organization: one person owns it, keeps all the profits, makes every decision, and is personally liable for all business debts and obligations.
A sole proprietorship is a business owned and operated by a single person. It's the simplest of the four major business organization types in AP Business (the others being partnership, LLC, and corporation, per EK 1.7.A.1). There's no legal separation between you and the business, which is what makes it both the easiest to start and the riskiest to run.
Because one person runs the whole show, that owner usually wears every hat. EK 1.7.B.1 spells this out: a sole proprietor may act as CEO, marketer, product developer, financial manager, and operations manager all at once. You keep all the profits and all the control. The flip side is that you're personally liable for everything the business owes (EK 1.7.A.3), so if the business can't pay a debt, creditors can come after your personal assets.
Sole proprietorship lives in Unit 1: Businesses, Competition, and New Ideas, specifically Topic 1.7. It anchors two learning objectives: AP Business 1.7.A asks you to compare the advantages and disadvantages of each business type, and AP Business 1.7.B asks you to define the roles and responsibilities of sole proprietors. The big idea is the trade-off. A sole proprietor gets total control and all the profits, but they trade that for unlimited personal liability and limited access to funding (EK 1.7.A.2), which makes the business hard to grow. Understanding that trade-off is the whole point of comparing it to corporations and LLCs.

A corporation is the sole proprietorship's opposite. Where one person owns and runs a sole proprietorship with full personal liability, a corporation separates the owners (shareholders) from the business, shields them from liability, and gives it far more access to funding. That's exactly the contrast 1.7.A wants you to make.
Limited Liability (Unit 1)
A sole proprietor has the opposite of limited liability. Limited liability means an owner can lose only what they invested, not their personal assets. A sole proprietor enjoys no such protection, so understanding limited liability is really understanding what a sole proprietorship lacks.
Partnership (Unit 1)
A partnership is basically a sole proprietorship with more than one owner. Partners split the roles based on their strengths (EK 1.7.B.2), but like sole proprietors they're still personally liable for business debts. Same liability problem, just shared.
Specialized Departments (Unit 1)
A sole proprietor does every job alone, but as a business grows it splits those jobs into departments like marketing, R&D, operations, and accounting (EK 1.7.C and 1.7.D). The sole proprietor is the before picture; specialized departments are the after.
Multiple-choice questions love to test this by description rather than by name. You'll get a scenario like a single owner who personally handles marketing, accounting, product development, and daily operations, and you pick the term that matches (that's a sole proprietorship). Watch for the partnership twist, where two people split duties by expertise. Questions also test liability directly, asking which structure lets owners avoid personal liability for debts, and the answer is never sole proprietorship. No released FRQ uses this term verbatim, but the comparison-and-contrast skill behind 1.7.A is exactly what a free-response prompt on business structures would reward.
Both have owners who are personally liable for business debts and who play multiple roles, so they feel similar. The difference is the headcount: a sole proprietorship has exactly one owner, while a partnership has two or more who divide responsibilities by their strengths and interests. If a question describes two people splitting client work and finances, that's a partnership, not a sole proprietorship.
A sole proprietorship is owned and run by one person, who keeps all the profits and all the decision-making control.
The owner is personally liable for all business debts and obligations, meaning creditors can reach personal assets.
A sole proprietor often plays every role at once, including CEO, marketer, product developer, financial manager, and operations manager.
Its main weakness is limited access to funding, which makes it hard to grow compared to a corporation.
On the exam, a one-owner business with full liability is a sole proprietorship, while two-plus owners make it a partnership.
It's the simplest business organization type: one person owns and operates the business, keeps all the profits, makes all the decisions, and is personally liable for every business debt. It's covered in Unit 1, Topic 1.7.
No. A sole proprietor has unlimited personal liability for business debts and obligations (EK 1.7.A.3). If you want liability protection, you'd organize as an LLC or corporation instead.
The number of owners. A sole proprietorship has exactly one owner; a partnership has two or more who split responsibilities by their strengths. Both share the same downside of personal liability for business debts.
The advantages are full control and keeping all the profits. The disadvantages are unlimited personal liability and limited access to funding, which makes it hard to grow the business (EK 1.7.A.2).
Usually all of them. Per EK 1.7.B.1, a sole proprietor may act as CEO, marketer, product developer, financial manager, and operations manager because there's no one else to delegate to.
