Writing a Business Plan
A business plan is not paperwork for its own sake. It is the document that forces an owner to answer every awkward question before spending the money, and it is the first thing a lender asks for when someone walks in wanting a loan.
📘 What you need to know
A business plan sets out what the business does and how the owners intend to develop it.
Its two main jobs: reduce risk by making the owner think everything through, and help raise finance.
Typical sections: the idea, market research, marketing plan, operations, people, costs and revenue, cash flow forecast, finance needed.
Lenders and investors use it to judge whether the business can repay and whether the idea has commercial merit.
It should be a living document, updated as the business grows and conditions change.
A plan does not guarantee success. It is built on forecasts, and forecasts can be wrong.
What goes in it
Every section exists because somebody will ask that question. Think of the plan as a list of answers waiting for the questions.
The last three sections are the ones lenders read most carefully. Everything above them explains where those numbers came from.
Why owners bother
There are two separate reasons, and exam answers score better when you keep them apart.
Reason
What it does for the business
Why it matters
Reduces risk
Forces the owner to research demand, costs and competition before spending
Many problems are cheaper to find on paper than after the shop has opened
Raises finance
Gives lenders and investors the evidence they need to say yes
Banks lend against forecasts and security, not against enthusiasm
Sets targets
Turns vague aims into numbers the owner can check against
You cannot tell if you are behind unless you wrote down where you should be
Aligns the team
Gives staff and partners one shared version of the plan
Stops two managers pulling the business in different directions
A lender is not reading your plan to see how excited you are. They are reading it to work out one thing: can this business generate enough cash, reliably enough, to pay me back? Write the cash flow section as if it is the only page they will read carefully, because it often is.
What a lender actually looks for
🧩 The bank’s mental checklist
Is the research real? Primary evidence beats “we believe there is demand”.
Do the numbers add up? Forecast revenue must match the market size and the pricing.
Is there a cash gap? A profitable business can still run out of money in month four.
What is the repayment plan? Amount, term, and what happens if sales come in 20% low.
Who is running it? Track record, skills and past credit history all count.
What security is offered? Assets the lender can claim if the plan fails.
The plan is one part of the decision, not all of it. Past credit history, the owner’s experience, the state of the economy and how convincing the owners are in person all feed into the lender’s answer. A strong plan improves the odds; it does not guarantee the loan.
Worked examples
WORKED EXAMPLE
Define the term business plan. [2 marks]
Step 1: the meaningA business plan is a written document setting out what a business does, its aims, and how the owners intend to achieve them [1].Step 2: what it containsIt normally includes market research, a marketing plan, forecast costs and revenue, a cash flow forecast and the finance required [1].2 marksmeaning plus contents is a safe two-mark structure
WORKED EXAMPLE
Harbour Sail Tours is a small family business with two boats. It wants to borrow $340,000 for a third, larger boat so it can run corporate group trips. Explain one advantage and one disadvantage of producing a business plan. [4 marks]
Advantage, then appliedThe plan lets the bank see forecast income from corporate trips against the repayments on $340,000 [1], so Harbour Sail is far more likely to be approved than if it simply asked for the money [1].Disadvantage, then appliedA proper plan takes time and expertise to write [1], and with only a handful of family staff running daily tours, Harbour Sail may have to pay an adviser or take the owners away from serving customers [1].4 marksthe size of the business is the application hook — use it
WORKED EXAMPLE
Discuss the implications for Harbour Sail Tours of producing a business plan. [10 marks — judgement extract]
The case forHarbour Sail is entering a new segment, corporate groups, that it has never served. The research needed for the plan would test whether that demand actually exists locally before it commits to a boat it cannot easily resell.The case againstThe forecasts rest on assumptions about corporate bookings the business has no history of. A confident-looking plan built on weak numbers can make a risky idea look safe.JudgementOn balance the plan is worth producing, mainly because the bank will not release $340,000 without one, but Harbour Sail should treat it as a working document and revise the forecasts after its first season of corporate trips rather than filing it away.Balanced, applied, with a clear decision“on balance … but …” is a reliable shape for judgement marks
How useful is a business plan?
Strength
Weakness
Makes the owner test the idea before spending
Built on forecasts, which can be optimistic or simply wrong
Usually required before a bank will lend
Takes time and skills a small business may not have
Creates targets that progress can be measured against
Can create false confidence if the research was shallow
Helps compare different sources of finance
Goes out of date fast in a changing market
Useful for attracting partners, landlords and key staff
A rigid plan can stop owners reacting to a better opportunity
💡 Exam tips
Name the sections that matter to the question. Do not recite all eight if only finance is being discussed.
Use the numbers in the case study, especially the amount being borrowed and the forecast revenue.
Distinguish profit from cash. Lenders worry about cash timing, not just the annual profit figure.
Mention that the plan should be updated. It is a quick, easy analysis point.
For “discuss”, say what the plan cannot do: it cannot create demand, and it cannot fix a weak idea.
Link it to other tools. The plan is where SWOT, STEEPLE and market research end up.
⚠ Common mix-ups
Treating the plan as a guarantee. It improves the odds; it does not remove risk.
Listing sections with no explanation. Say why each one matters to this business.
Confusing a cash flow forecast with a profit forecast. They answer different questions.
Assuming only start-ups need plans. Established firms write them for every major investment.
Forgetting the cost of writing it in time and expertise, which matters most for small firms.
Saying “the bank will definitely lend”. Credit history and security also decide the outcome.
Up next: Using Decision Trees — the plan says what you intend to do. A decision tree puts numbers on two competing options so you can compare them properly.
