How to Write a Business Plan: Template and Steps
To write a business plan, describe the problem, your solution, your customers, your market, how you will reach and sell to them, who is on the team, and what you expect to spend and earn. Start with a one-page lean version, then expand into a full plan only if a lender, partner or investor asks for it.
What a business plan is for
A business plan is a written explanation of what your company will do, for whom, how it will make money, and what you need to get there. It is a thinking tool first and a document second. Writing it forces you to find the holes in your idea while fixing them is still cheap.
It also serves different readers. You might write one to organize your own decisions, to convince a bank to lend you money, to bring on a partner, or to support a grant application. Investors in startups often care more about a pitch deck than a long plan. Know your reader before you write a word, because the same facts get emphasized differently.
Do you even need one?
If you are applying for a bank loan, a government-backed loan or many grants, you will almost certainly need a written plan. If you are starting a small business on your own money, a short plan still helps you decide whether the numbers work. If you are raising venture capital, a deck and a financial model usually come first. In every case, the exercise of planning matters more than the paper.
The U.S. Small Business Administration describes two common formats, a traditional plan and a lean plan. Its page on writing a business plan is linked at the bottom of this guide. We follow the same basic distinction here.
Traditional plan vs lean business plan
A traditional business plan is long, often thirty pages or more, and detailed. It suits lenders and anyone who wants a thorough document. A lean business plan is short, often one page, and lists key points in brief bullets. It is quicker to write, easier to update and good for your own planning.
| Traditional plan | Lean plan | |
|---|---|---|
| Length | Many pages | One to a few pages |
| Time to write | Days to weeks | An afternoon |
| Style | Full paragraphs, detailed research | Bullets and short phrases |
| Best for | Bank loans, formal applications, partners | Early planning, quick tests, regular updates |
| Updating | Heavy | Easy |
If you are unsure, start lean. A one-page version tells you quickly whether you understand your own business. You can expand it later without losing anything.
The one-page business plan
A one-page plan answers nine questions in a few lines each:
- What problem are you solving, and for whom?
- What is your solution?
- Why is it better than the current alternatives?
- How will you reach customers?
- How will you make money?
- What are your main costs?
- What do you need to be true for this to work (your key assumptions)?
- What are the key numbers you will track?
- Who is on the team, and what do they bring?
If you can fill that page honestly, you have the skeleton of every longer plan.
Business plan sections: a template you can copy
Here is a section-by-section outline for a traditional plan. For a lean plan, compress each section into a few bullets.
1. Executive summary
Write it last, even though it goes first. One page at most. State what the company does, who it serves, why now, how it makes money, what you are asking for (funding, a loan, a partner), and one or two facts that show you have momentum. A busy reader may only read this page.
2. Company description
What your business is, its legal structure, where it is based, and its mission in plain words. If you are choosing a structure, read our guide to LLC vs C corp for startups. Include your stage: idea, building, launched or growing.
3. Problem and solution
Describe the pain point in the customer's words. Then explain your solution and why it is different. Concrete examples beat adjectives.
4. Market analysis
Who are your customers, how many could there be, and who else serves them? Explain how you estimated the size. A TAM, SAM and SOM breakdown works well: the total market, the part you can reach, and the part you can realistically win first. Describe competitors honestly, including doing nothing or using a spreadsheet.
5. Products and services
What you sell, how it works, what stage it is in, and what comes next. If you plan an early test version, mention your MVP plan.
6. Marketing and sales plan
How customers will find you and what it will cost to win each one. List channels you will try first, pricing, and the steps from first contact to payment. Tie this to a go-to-market strategy if you have one.
7. Operations
How the work gets done: suppliers, tools, locations, key processes, and what you will outsource. Keep it concrete: who does what in a normal week.
8. Team and organization
Founders, key hires, advisors, and what experience each person brings. Be honest about gaps and how you will fill them. Investors often care about the team more than any other section.
9. Financial plan
Projected revenue, costs, profit or loss, and cash needs, usually for three to five years, monthly for the first year. Include your assumptions in plain language so the reader can challenge them. See the worked example below.
10. Funding request and use of funds
If you are asking for money, say how much, what type (loan, equity), and exactly what it will pay for. This is also where you describe how long the money lasts. For background, see how to raise capital for your startup.
11. Appendix
Supporting material: resumes, letters of intent, quotes, research, permits and legal documents. Keep the main plan short and put the proof here.
The financial section: a simple worked example
The financials scare many first-time founders, but the logic is simple. You are estimating how much money comes in, how much goes out, and when. All numbers below are made up for illustration.
For example, imagine a small online course business. You assume you will sell 20 courses a month at $100 each, so revenue is $2,000 a month. Your costs are $500 a month for software and $600 for ads, so $1,100 total. Monthly profit would be $900. If setup costs are $3,000 up front, you would break even after roughly four months of those numbers. This is the idea behind the break-even point.
What to include
- Revenue forecast. Built from the bottom up: customers times price times how often they buy, not "we will get 1 percent of a huge market."
- Costs. Fixed (rent, software, salaries) and variable (materials, payment fees).
- Cash flow. When money actually arrives and leaves. A profitable business can still run out of cash.
- Startup costs. One-time expenses to get going. See the business startup budget guide.
- Assumptions. A short list explaining where each key number came from.
Show a realistic case. Optionally add a cautious case and an optimistic one. Readers trust a plan that shows its work.
An accountant can help
If the plan is going to a bank or investor, have an accountant or experienced advisor review the numbers. This is general education, not financial advice for your situation.
Business plan for investors vs for a bank
Different readers want different things. Write to the one who will decide.
| Reader | What they mainly want to know | What to emphasize |
|---|---|---|
| Bank or lender | Can you repay the loan, and what if things go wrong? | Cash flow, collateral, existing revenue, personal credit and experience, a conservative forecast |
| Equity investor | Could this become very large, and why will you win? | Market size, traction, team, growth plan, how they get a return |
| Grant provider | Does your project meet our goals? | Mission fit, measurable outcomes, a clear budget |
| Partner or supplier | Is this worth working with? | Your reliability, volumes, plans and terms |
For a lender
Lenders get paid back from your cash, not from your upside. They look for steady revenue, a realistic budget and reasons to believe you will repay. Expect them to ask about your personal finances and any collateral. The SBA's page on funding a business, our grants guide and the funding-stages overview in startup funding stages help you see which door fits.
For an investor
Equity investors accept the risk of losing their money in return for the chance of a large gain. They want evidence of a big market, a team that can execute, and early proof, such as users, revenue or pilots. Many will ask for a short deck rather than a long plan, so prepare both. Our guide to how to value a startup covers what happens when numbers meet negotiation.
Common business plan mistakes
- Hockey-stick forecasts with no logic. Revenue that rockets upward with no explanation of how you will win those customers erodes trust fast.
- "We have no competitors." Customers always have an alternative, even if it is a spreadsheet or doing nothing. Naming it shows you understand the market.
- Market size by percentage. "If we get just 1 percent of the market" is a warning sign to experienced readers. Build the estimate from the ground up.
- Too long, too vague. Pages of general statements say less than one page of specifics.
- Burying the ask. If you want money, say how much and for what.
- Ignoring costs and risks. Every business has risks. List yours and say how you will manage them.
- Writing it once and filing it away. A plan is a living document. Update it when your assumptions meet reality.
- Skipping legal and permit steps. Check our startup legal checklist and local licensing rules before you promise a launch date.
Step by step: writing your plan this week
- Pick the reader. Yourself, a bank, an investor or a partner. That decides length and emphasis.
- Fill out the one-page version. Answer the nine questions above in an hour.
- Test the weak spots. Anywhere you wrote "I think" or "probably," do a little research or talk to a customer. See how to validate a startup idea.
- Do the math. Build a simple monthly spreadsheet for revenue, costs and cash for the first year.
- Expand into the full template only if you need a longer plan.
- Write the executive summary last.
- Ask someone to read it cold. A person who knows nothing about your business should be able to say what you do after a single page.
- Set a review date. Revisit the plan every quarter or when something major changes.

Frequently asked questions
How do I write a business plan for a startup?
Start with a one-page lean plan covering the problem, solution, customers, how you will reach and sell to them, costs, key assumptions and team. Then expand into sections such as market analysis, operations and financial projections if a lender, partner or investor asks for a full document.
What are the main sections of a business plan?
A typical plan includes an executive summary, company description, problem and solution, market analysis, products and services, marketing and sales, operations, team, financial plan, a funding request if you need one, and an appendix. Lean plans compress these into short bullets.
What is a lean business plan?
A lean business plan is a short version, often one page, that lists the key points of your business in brief bullets instead of long paragraphs. It is quick to write, easy to update, and useful for early planning, though some lenders still want the full traditional version.
How long should a business plan be?
It depends on the reader. A lean plan can fit one page. A traditional plan for a lender or formal application is often many pages. Shorter is better if it covers the essentials, and long plans should put supporting documents in an appendix.
Do investors read business plans?
Some do, but early-stage startup investors often start with a short pitch deck and a summary, and ask for more later. Have a plan or financial model ready so you can answer detailed questions, but do not assume the whole document will be read.
What is the difference between a business plan for a bank and for investors?
A bank wants to know you can repay a loan, so it focuses on cash flow, collateral and conservative forecasts. An equity investor wants to see a large market, strong traction and a team that can grow quickly. The facts are the same; the emphasis is different.
Do I need a business plan to start a business?
Not legally. But you will usually need one to apply for a bank loan or many grants, and writing one helps you test your numbers even when nobody asks. A short plan is a sensible minimum for almost any new business.
