Revision and practice on the internal and external sources of finance available to a business, and their advantages and disadvantages.
Key vocabulary: Retained Profit, Overdraft, Crowdfunding, Sale of Assets
Key Concepts
Internal vs External Finance
Businesses often want to expand and invest in the short, medium and long term, and have access to a wide variety of different finance options.
Internal finance: money a business can raise from within the firm itself.
External finance: money raised from outside the firm.
Internal Sources of Finance

Description
Key advantage
Key disadvantage
Owners' investment
Finance provided directly by the business owner(s) from their personal savings — also known as owner's capital.
No debt or interest; owner keeps full control.
Limited amount available; high personal risk.
Retained profit
Profit kept in the business rather than paid out as dividends, accumulated over time.
No interest or repayment obligations; keeps full ownership and control.
Only available if the business is already profitable; may cause shareholder dissatisfaction if dividends are cut.
Sale of assets
Selling items of value the business owns but no longer needs, to raise cash.
No debt or interest; immediate cash injection.
A one-off source; the asset is lost for good, possibly at a poor price.
Sale and leaseback
Selling an asset the business owns (typically property) and immediately leasing it back from the new owner on a long-term basis.
Large cash injection while keeping use of the asset.
Loses ownership of a valuable asset; creates a new, ongoing leasing cost.
Working capital
The money available for day-to-day operations, calculated as current assets minus current liabilities.
Immediately available with no interest or external obligations.
Using it can weaken day-to-day operations; limited amount available.
External Sources of Finance

Description
Key advantage
Key disadvantage
Trade credit
Credit extended by suppliers allowing a business to buy goods and pay later, typically after 30-60 days.
Interest-free; improves short-term cash flow.
Can strain supplier relationships if payments run late; may lose early-payment discounts.
Share capital
The amount shareholders have invested in the business by purchasing shares — a permanent source of financing.
Large amounts of finance can be raised, with no repayment or interest.
Existing owners lose some control; shareholders expect dividends.
Overdraft
A short-term borrowing facility allowing a business to spend more than its bank balance, with interest charged on the overdrawn amount.
Flexible — interest is only paid on the amount used, and it can be arranged quickly.
Banks can recall the facility; interest costs add up if overused.
Loans
Money borrowed from a bank or lender that must be repaid over time, plus interest.
The business keeps full ownership and control.
Regular repayments must be made; a lender can seize a security asset if repayments are missed.
Business angels
A wealthy individual investor who provides capital to early-stage or growing businesses in exchange for equity (an ownership stake).
Brings capital, expertise and useful networks, not just money.
Angels typically want high returns and may push for changes to strategy or lose the entrepreneur some ownership.
Private equity
Investment from specialist firms that raise large sums to buy a controlling stake in established businesses, aiming to restructure and improve them before selling on for a profit.
Access to capital and management expertise, with a clear strategic focus.
Loss of control; can mean aggressive cost-cutting and increased debt.
Crowdfunding
Raising finance by collecting small amounts of money from a large number of people, usually through an online platform.
Builds market validation, marketing and public awareness alongside the money raised.
No guarantee of success; involves public exposure of the idea.
Real-World Case Studies
Tembo — crowdfunding a product to market in weeks
Tembo launched a Kickstarter crowdfunding campaign in March 2026 and became an instant hit, raising over $2.1 million (around £1.65 million) within weeks. Crowdfunding suited a product launch like this well: rather than needing a bank to approve a loan or an investor to agree a valuation, Tembo could raise the money directly from thousands of future customers — while the scale of interest also worked as free market validation and marketing before a single unit had shipped.

Superdry — combining owners' investment and sale of assets to avoid more debt
When Superdry went private in July 2024 to carry out a three-year restructuring plan, founder and CEO Julian Dunkerton was reportedly wary of any deal that would add to the company's existing debt load. Instead, the rescue plan combined two other sources of finance: Dunkerton personally added £21 million through a new equity raise (owners' investment), and the company sold its Asian intellectual property rights for around £60 million (sale of assets). This shows how a business under financial pressure can choose sources of finance specifically to avoid increasing its gearing, even when a straightforward loan might otherwise seem the quickest option.

A*/A Stretch
Examiner's eye
When recommending a source of finance in an exam answer, always link your choice to the business's size, stage of growth, and the amount and urgency of the finance needed — a start-up recommending a share flotation, or an established PLC recommending crowdfunding for a major investment, both suggest a weak understanding of the context.
Synoptic link
Connecting to gearing (L1, this unit): Every external source of finance that involves debt (loans, overdrafts) increases a business's gearing, while share capital and internal sources do not. A strong exam answer on "which source of finance should a business use" often weighs this gearing impact directly against the objective of keeping the finance interest-free or keeping full control.
Try This With AI
Before using this: AI tools can get facts or mark scheme details wrong, and quality varies by tool. Always check anything factual against your notes or ask your teacher.
Describe a fictional small business that needs to raise £50,000 for a specific reason (e.g. new equipment, a new store, or an app launch). Ask me to recommend the most suitable source of finance and a back-up option, with reasons. Then tell me whether my reasoning considered the business's size, control, and ability to repay — and suggest what I could add.
