The Sole Trader: Autonomy and Accountability
A sole trader is the simplest business structure, owned and operated by a single individual. There is no legal distinction between the owner and the business itself. This offers complete control over all decisions and the right to all profits. However, this structure carries significant personal risk due to unlimited liability. This means the owner is personally responsible for all business debts, and personal assets like their home or car could be used to settle them. Raising finance can also be challenging, often limited to the owner's personal savings, retained profits, or small bank loans, which can constrain growth potential. The business has no separate legal status, so its continuity is linked directly to the owner.
Owned and controlled by one person.
Unlimited liability: Owner's personal assets are at risk.
Finance is typically limited to personal savings and small loans.
The business is not a separate legal entity from the owner.
When analysing a sole trader, always link the benefit of total control to the significant drawback of unlimited liability. Examiners look for this balanced understanding of risk versus reward.
Partnerships: Sharing the Load and the Liability
A partnership is a business owned by two or more individuals (typically 2-20 in an ordinary partnership). Partners share the responsibilities, risks, and profits. This structure allows for a greater injection of capital and a wider range of skills compared to a sole trader. However, most partnerships still have unlimited liability, meaning all partners are jointly and severally liable for the business's debts. Control is shared, which can lead to disagreements if partners have different visions. A 'Deed of Partnership' is a crucial legal document that outlines profit-sharing ratios, roles, and procedures for a partner leaving, helping to prevent future conflicts. Without one, disputes are settled according to the Partnership Act 1890, which may not suit the partners' original intentions.
Owned by 2 or more people, pooling capital and expertise.
Unlimited liability is shared between partners.
A Deed of Partnership is vital for defining roles and resolving disputes.
Decision-making is shared, which can be a source of both strength and conflict.
In questions about partnerships, always evaluate the importance of the Deed of Partnership. Stating that it helps prevent and resolve conflict demonstrates a deeper level of business understanding.
Private Limited Company (Ltd): Protection and Privacy
A private limited company (Ltd) is an incorporated business, meaning it has its own separate legal identity, distinct from its owners (shareholders). The most significant advantage of this is limited liability: shareholders are only liable for the amount they have invested in shares. Their personal assets are protected. Finance can be raised by selling shares to friends, family, and other private investors, but not to the general public. This allows for more capital than a sole trader or partnership while retaining control within a relatively small group. The business enjoys perpetual continuity, as ownership can be transferred through the sale of shares without disrupting operations. However, setting up an Ltd involves more legal formalities and the company's accounts must be filed publicly.
A separate legal entity from its owners.
Provides limited liability, protecting shareholders' personal assets.
Shares can only be sold privately, not on a public stock exchange.
Greater access to finance than unincorporated businesses but more complex to set up.
The concept of a 'separate legal entity' is the foundation for understanding limited companies. Be sure to explain that this legal separation is what enables limited liability and perpetual continuity.
Public Limited Company (PLC): Expansion and Exposure
A public limited company (PLC) is an incorporated business that can offer its shares for sale to the general public via a stock exchange. This provides access to vast amounts of capital, facilitating large-scale expansion, acquisitions, and investment. Like an Ltd, it offers limited liability to its shareholders. However, this access to capital comes at a cost. PLCs face stringent regulatory requirements, including the publication of detailed financial reports, making them subject to intense public and media scrutiny. The original owners often see their control diluted as ownership spreads amongst thousands of shareholders. This can lead to a 'divorce between ownership and control' and makes the company vulnerable to hostile takeovers if its share price falls.
Can sell shares to the general public on a stock exchange.
Potential to raise very large amounts of capital for growth.
Subject to high levels of regulation and public scrutiny.
Risk of 'divorce between ownership and control' and hostile takeovers.
When discussing PLCs, focus on the trade-off. The main advantage is access to capital, but the main disadvantages are the loss of control and the increased regulatory burden. High-level answers will evaluate this trade-off in the context of a specific business scenario.
Worked examples

Two architects want to expand nationally, need $2m for offices and IT. Compare partnership vs Ltd vs PLC.

Partnership: Unlimited liability risky with $2m debt; limited to partners' personal assets for finance — insufficient.
Anjali and Ben are in a partnership. Their partnership deed specifies the following terms:
- Anjali receives an annual salary of
- Interest is paid on capital at a rate of 5% per annum. Anjali's capital is $80,000 and Ben's is $50,000.
- Remaining profits are shared in the ratio 3:2 (Anjali:Ben).
In 2023, the business made a net profit of $120,000. Calculate the total amount each partner received.

The calculation follows the order specified in the partnership deed: salaries, then interest on capital, then profit share.
