5.2 Sources of finance

Owners can finance a business through retained profit or additional capital, while legal form affects access to shares, borrowing, liability and control. Finance is linked to governance as well as cash.

Retained profit avoids interest and new owners but may be limited. Share finance can raise substantial funds but dilute control; debt preserves ownership but creates repayment risk.

A private company might reinvest profit for a small expansion, while a public company can issue shares but face disclosure and shareholder expectations.

A source is not “cheap” without considering control, risk, timing and opportunity cost.

Internal finance comes from within the business, such as retained profit or sale of assets. External finance comes from outside, such as loans, overdrafts, trade credit, leasing or share capital.

Internal funds avoid some interest or dilution but may be insufficient and have opportunity cost. External funds add capacity but bring repayment, security, information or control conditions.

Selling an unused vehicle may fund a modest upgrade; a new factory usually needs a larger external source and a plan for repayment or investor return.

Internal does not mean free, and external does not always mean long-term debt.

Choose a finance source by comparing amount, duration, cost, security, repayment, speed, risk, flexibility and impact on ownership. The need and the business context come first.

Short-term working capital should not usually be funded with an inflexible long-term commitment, while a long-lived asset should not depend on a source that must be repaid immediately.

Trade credit may bridge inventory purchases, whereas a term loan or lease may match equipment life; a start-up with uncertain cash flow needs a different mix from a mature firm.

The lowest interest rate is not necessarily the lowest total cost once fees, security, risk and control are included.

Selecting finance means matching the amount, duration, cost, risk, security and control effects of a source to the business need.

A firm should compare what it can repay, what assets or ownership it can offer, how quickly it needs funds and what uncertainty it faces.

A seasonal retailer may use an overdraft for short timing gaps but a term loan for equipment; choosing the reverse can create avoidable repayment pressure.

The “cheapest” source depends on total cost, flexibility, security and control—not just the headline rate.
