Sources of business finance
Starting and running a business takes money. Short-term finance - overdrafts and trade credit - covers day-to-day gaps; long-term finance - savings, venture capital, share capital, loans, retained profit and crowdfunding - pays to start and grow.

Learning Objectives
- 1Explain why businesses need finance.
- 2Explain the short-term sources of finance: overdraft and trade credit.
- 3Explain the long-term sources of finance: personal savings, venture capital, share capital, loans, retained profit and crowdfunding.
- 4Choose a suitable source of finance for a business and justify the choice.
Why Businesses Need Finance
Every business needs money - to start, to keep going and to grow.
-
Starting up
Buying equipment, premises, stock and paying for marketing before any sales are made.
-
Day to day
Covering a gap when cash goes out before it comes in.
-
Growing
Opening another branch, launching a new product or buying bigger machines.
-
Short or long term
Short-term finance is repaid within a year; long-term finance is used for a year or more.
Overdraft
An overdraft lets a business spend more money than it has in its bank account, up to an agreed limit.
-
How it works
The bank agrees a limit, such as £2,000, and the account can go below zero up to that amount.
-
Advantages
Flexible - the business only borrows what it needs, when it needs it - and quick to arrange.
-
Disadvantages
Interest rates are high, and the bank can ask for the money back at short notice.
-
Best for
Covering a short cash gap, such as a quiet month before sales pick up.
Trade Credit
Trade credit is when a supplier lets a business pay for goods some time after it receives them.
-
How it works
A supplier delivers stock now, and the business pays in, say, 30 or 60 days.
-
Advantages
The business can sell the goods before it has to pay for them, and there is no interest if it pays on time.
-
Disadvantages
New businesses may not be offered it, and paying late can mean penalties and a damaged relationship with the supplier.
-
Best for
Buying stock and materials.
Supplies Now, Pay Later
Trade credit is one of the cheapest sources of finance there is. If the shop can sell this stock before the invoice is due, the supplier has, in effect, lent it the money for free.
With trade credit, the stock arrives today and the bill is paid in 30 days.
Long-Term Sources of Finance
-
Personal savings
The owner's own money. No interest and nothing to repay - but the owner risks losing it, and may not have enough.
-
Loan
A fixed amount borrowed from a bank, repaid with interest in regular instalments. Predictable, but interest must be paid, and the bank may want security.
-
Share capital
Money raised by selling shares - part-ownership - in the business. Nothing to repay, but the owner gives up some control and profit.
-
Venture capital
Investment from specialists in new, risky businesses with high growth potential, in return for a share of the business. Brings expertise, but loses some control.
-
Retained profit
Profit kept in the business rather than paid to the owners. No interest or repayment - but a new business has none yet.
-
Crowdfunding
Many people each invest a small amount, usually through a website, often in return for a reward or a share. Also tests demand, but the target may not be reached.
Two Ways to Raise Money
A loan from one lender, or small amounts from many people.
A bank loan: one lender, repaid with interest.
Crowdfunding: many people, small amounts.

-
Retained profit

-
Crowdfunding

Choosing the Right Source
The best source depends on the business and what the money is for.
-
What it is for
Short-term needs (stock, a cash gap) suit short-term finance; long-term needs (equipment, premises) suit long-term finance.
-
How much is needed
Savings may cover a small amount; a large sum may need a loan, share capital or venture capital.
-
New or established
A new business has no retained profit and may struggle to get a loan or trade credit.
-
Cost
Interest makes loans and overdrafts expensive; share capital and venture capital cost the owner control and future profit.
-
Control
An owner who wants to stay in charge may prefer a loan to selling shares.
Case study
BrewDog: Crowdfunding a Brewery
BrewDog was founded in Scotland in 2007 by James Watt and Martin Dickie. In 2009 it launched "Equity for Punks", inviting its customers to buy small shares in the business online. Over the following years it raised tens of millions of pounds from more than 100,000 people - money it used to build new breweries and open bars. The investors became some of its most loyal customers, and BrewDog avoided having to rely on a bank or a single large investor.
Match the Money to the Business
Recommend the best source of finance for each, and explain why: a café that needs £800 to cover a quiet February; a new tech start-up that needs £500,000 to develop an app; a successful bakery that wants a £20,000 oven; a student starting a dog-walking business that needs £150 for leads and flyers.
1. Decide: short term or long term?
2. Consider how much is needed.
3. Consider whether the business is new or established.
4. Recommend a source and justify it.
A good answer shows: A suitable source for each - overdraft, venture capital, retained profit or a loan, and personal savings - with a reason linked to the amount, the purpose and the type of business.

A bank loan.
Outline one disadvantage to a business of using an overdraft.
Mark scheme — 2 marks available
- A disadvantage identified, e.g. high interest / can be withdrawn at short notice — 1 mark
- Developed: the effect on the business — 1 mark
Model answer
Interest rates on overdrafts are high (1), so borrowing this way for a long time increases the business's costs and reduces its profit (1).
Explain one benefit to a new business of using crowdfunding.
Mark scheme — 3 marks available
- A benefit identified, e.g. tests demand / no interest / publicity / raises money without a bank — 1 mark
- First linked point of explanation — 1 mark
- Second linked point of explanation — 1 mark
Model answer
It can test demand for the product (1). If many people are willing to invest or pre-order, it shows the owner that customers want it (1). This reduces the risk of launching a product nobody buys, as well as raising the money needed to start (1).
Source: Tom is starting a mobile coffee van business. He needs £18,000 to buy and fit out the van. He has £5,000 of savings. He has two options for the remaining £13,000. Option 1: A bank loan over four years at 9% interest. Option 2: Sell a 30% share of the business to a friend who has experience of running a café. Justify which one of these two options Tom should choose.
Mark scheme — 9 marks available
- AO2 (Application, 3 marks): uses Tom's context - the van, £5,000 savings, £13,000 needed, 9% interest, a 30% share — Level 1-3
- AO3a (Analysis, 3 marks): chains of reasoning about each option — Level 1-3
- AO3b (Evaluation, 3 marks): a justified choice with a supported judgement, e.g. "it depends on" — Level 1-3
Model answer
Option 1, a bank loan, lets Tom keep full control and all of the profit, because the bank does not own any of the business. The repayments are fixed, so he can plan his cash flow. However, he must pay interest on top of the £13,000, and the repayments must be made every month even when sales are low, which is risky for a new business with no track record. Option 2, selling a 30% share, means there is nothing to repay and no interest, so his cash flow in the early months is safer. His friend's café experience could also help him avoid mistakes. But Tom would give up 30% of his future profit for as long as the business runs, and would have to share decisions. On balance Tom should choose Option 1, because a coffee van is a relatively simple business with steady daily sales, so he should be able to cover the repayments, and over time the interest will cost him less than giving away 30% of the profit. However, this depends on his cash-flow forecast showing he can make the repayments in quieter winter months.
Which one of the following is a short-term source of finance?
Why: Overdrafts and trade credit are the short-term sources. The others are long-term.
A new business owner wants to raise money without paying interest and without giving up any control. Which source suits them best?
Why: Personal savings have no interest and the owner keeps full control - but the owner risks their own money.
Why can a brand-new business NOT use retained profit?
Why: Retained profit comes from profits made in the past, and a new business has not made any yet.
What does a business give up when it raises money through venture capital?
Why: Venture capitalists invest in return for a share of the business, so the owner gives up some control and future profit.
