Internal and External Sources of Finance

This lesson covers AQA A-Level Business topic 3.5.3 — sources of finance. You will learn about the full range of internal and external sources available to businesses, the distinction between short-term and long-term finance, and how to evaluate which sources are most appropriate in different business contexts.

Internal Sources of Finance

Internal sources of finance come from within the business itself. They do not require borrowing from or selling shares to external parties.

1. Retained Profits

Key Definition: Retained profits are the portion of a business's profits that are kept (retained) within the business after dividends have been paid to shareholders. They are reinvested in the business.

• The most common source of finance for established businesses.
• No interest payments and no dilution of ownership.
• Only available if the business is profitable and has been trading for some time.
• Opportunity cost: shareholders may prefer higher dividends.

2. Sale of Assets

A business can raise cash by selling assets it no longer needs — such as surplus land, buildings, vehicles, or equipment.

• Provides a one-off cash injection.
• Removes the maintenance and depreciation costs of the asset.
• Only works if the business has assets to sell and can find a buyer at a reasonable price.
• Reduces the asset base of the business, which may limit future capacity.

3. Reducing Working Capital

A business can release cash by tightening its management of working capital:

• Reducing inventory levels (freeing up cash tied up in stock).
• Collecting receivables more quickly (chasing customer debts).
• Delaying payments to suppliers (though this risks damaging relationships).

This is a short-term measure and must be managed carefully to avoid damaging operations.

4. Owner's Capital

In sole traders and partnerships, the owner(s) may inject personal savings into the business. This is internal in the sense that it comes from the owners rather than external lenders.

External Sources of Finance

External sources of finance come from outside the business — from lenders, investors, or other third parties.

Short-term External Sources

Source	Description	Advantages	Disadvantages
Bank overdraft	Allows the business to spend more than is in its bank account, up to an agreed limit	Flexible — only pay interest on the amount used; can be arranged quickly	Higher interest rate than loans; can be called in at any time; not suitable for large amounts
Trade credit	Suppliers allow the business to buy now and pay later (typically 30-90 days)	No interest charge; widely available; improves short-term cash flow	Lose early payment discounts; must be managed to avoid late payment penalties
Debt factoring	Selling trade receivables to a specialist company (a factor) at a discount for immediate cash	Immediate cash; outsources credit control	Factor takes a fee (typically 1-5% of invoice value); customers may perceive the business negatively
