AQA A-Level Accounting: Types of Business Organisation — Revision Notes

Condensed for the final weeks. For the full explanation, use the Types of Business Organisation study guide.

The four ownership types

Type	Owners	Liability	Reporting burden
Sole trader	1 person	Unlimited	Light — no statutory filing
Partnership	2+ people	Unlimited (ordinary partners)	Light — governed by agreement or Partnership Act 1890
Private limited company (Ltd)	Shareholders (shares not publicly traded)	Limited	Must file accounts under company law
Public limited company (plc)	Shareholders (shares publicly traded)	Limited	Most extensive — public disclosure + audit requirements

Build this table once, from memory, covering all three dimensions the specification names: formation/ownership, benefits/risks, reporting requirements — this section is regularly tested by asking candidates to compare two types directly.

“Limited” ≠ small. A common misunderstanding: “limited” refers to a limit on the owner’s financial liability, not a limit on the business’s size or turnover.

Sources of finance by ownership type

Source	Sole trader	Partnership	Ltd	plc
Owner’s/partners’ capital	✓	✓	—	—
Bank overdraft/loan/mortgage	✓	✓	✓	✓
Ordinary shares	—	—	Limited	✓ (main route for large-scale issue)
Debentures	—	—	✓	✓

Match each source to which ownership types can realistically access it, and why — this converts a rote list into examinable understanding.

Worked example: comparing finance sources

Sole trader vs. public limited company:

Sole trader
  Source: owner's capital, bank overdraft, bank loan
  Risk:   unlimited liability -- a loan default can put personal
          assets at risk; finance is limited by the owner's own
          resources and creditworthiness

Public limited company
  Source: ordinary shares (issued to the public), debentures, bank
          loan
  Risk:   issuing shares DILUTES existing ownership and control;
          debt finance carries interest obligations regardless of
          profitability, but liability is limited to the value of
          shares held

Structure every finance-source answer around a named source with a specific risk attached — this is what distinguishes a strong answer from an unstructured list.

Worked example: choosing a structure as a business grows

A sole trader’s business has grown to the point where she wants to raise a large amount of finance to expand and is comfortable sharing control. Which structure(s) become realistic options, and why?

Option 1: Take on a partner (partnership)
  Gains access to another partner's capital, but liability remains
  unlimited for ordinary partners -- personal assets still at risk.

Option 2: Convert to a private limited company (Ltd)
  Gains limited liability, and can bring in outside shareholders
  without offering shares to the general public -- but faces
  statutory accounts filing for the first time.

Option 3: Float as a public limited company (plc)
  Gains access to large-scale finance via public share issue and
  debentures, but faces the most extensive reporting/audit burden
  and significant dilution of the original owner's control.

Working through a scenario like this – rather than only comparing structures in the abstract – is close to how exam questions on this content are actually phrased, since AQA typically frames Topic 3.2 questions around a business facing a specific growth or finance decision.

Key terms

Sole trader — one owner, unlimited liability. Partnership — 2+ owners sharing capital/profits/liability, governed by agreement or the Partnership Act 1890 by default. Private limited company (Ltd) — limited liability, shares not offered to the public. Public limited company (plc) — limited liability, shares publicly tradable, more extensive statutory reporting. Unlimited liability — personal assets can settle business debts. Limited liability — owner’s loss capped at the amount invested.

A note on partnership agreements

Where partners have not drawn up their own written agreement, the Partnership Act 1890 applies by default – and its default terms are often less favourable than a bespoke agreement would be (for example, profits are shared equally regardless of unequal capital contributions, and no partner is entitled to a salary unless the agreement says so). Knowing that the Act is a fallback, not a requirement to have one, is a specific point worth stating precisely if a question asks about partnerships without an agreement in place.

Common mistakes

• Listing the four ownership types without comparing benefits, risks and reporting when asked.
• Assuming all four have the same reporting requirements — limited company status brings materially different statutory obligations.
• Naming a finance source without linking it to which ownership types can access it.
• Treating “risk” as only financial — the specification also expects understanding of risks connected to liability, control and reporting.

Where this leads later in the specification

This section connects directly to Topic 7 (Limited Company Accounts) and Topic 15 (Partnership Accounts), where the accounting treatment specific to each structure is developed in full. Understanding the ownership and finance differences here first makes that later, more technical content considerably easier to follow — treat this as foundational vocabulary, not a self-contained block to revise once and set aside.

Quick self-test

• Name the four business ownership types and one defining characteristic of each.
• Explain why a plc faces more extensive reporting requirements than a sole trader.
• State two finance sources available to a private limited company that are NOT available to a sole trader.
• Explain the difference between unlimited and limited liability using a concrete example.
• Explain why issuing ordinary shares dilutes ownership and control.
