How Do I Write a Business Plan? (With a Simple Template)
The 9 sections of a business plan, what lenders look for, a one-page template, and the mistakes to avoid.
A business plan explains what you sell, who buys it, how you'll reach them and how the numbers work. Cover the executive summary, company description, market analysis, products, marketing and sales, operations, management, financial plan and any funding request. Start with a one-page lean plan and expand it if a lender asks.
In this article
A business plan is a written roadmap that explains what your business does, who it serves, how it will make money and what you need to get there. If you're applying for a bank loan or raising money from investors, you'll need a formal one. If you're starting a small business on your own savings, a short plan still forces you to answer the hard questions before they cost you money.
Do you need a traditional or a lean business plan?
| Lean (one-page) plan | Traditional plan | |
|---|---|---|
| Length | 1 to 2 pages | 15 to 40 pages |
| Best for | Self-funded startups, side businesses, testing an idea | Bank or SBA loans, investors, complex businesses |
| Time to write | An afternoon | Several weeks |
| Financials | Key numbers and assumptions | Detailed 3- to 5-year projections |
Start with a lean plan. You can expand it into a traditional plan when a lender or investor asks.
The 9 sections of a business plan
1. Executive summary
A one-page overview of the whole plan: what you do, who for, why you'll win, how you make money, how much funding you need and what for. Write it last, even though it comes first.
2. Company description
Your business name, structure (such as an LLC), location, mission, and the problem you solve. Explain what makes you different: price, quality, speed, expertise, location or a specialized niche.
3. Market analysis
Describe your target customer in detail: who they are, where they are, what they buy today and how much they spend. Estimate your market size, and list your main competitors with their strengths and weaknesses. Use real sources such as government data, industry reports and your own customer interviews.
4. Products and services
What you sell, how it works, pricing, and how you'll deliver it. If you rely on suppliers, intellectual property or technology, explain it here.
5. Marketing and sales plan
How customers will find you and why they'll buy: your channels (search, social media, referrals, partnerships, direct sales), your sales process, and your customer acquisition costs if you know them. Our guide to marketing a small business can help you fill this in.
6. Operations plan
How the business runs day to day: location, equipment, suppliers, hours, key processes, technology and any licenses or permits you need.
7. Management and organization
Who runs the business, their experience, and who else you'll hire or contract. Lenders and investors invest in people as much as ideas.
8. Financial plan
This is where most plans are weakest and where lenders look hardest. Include:
- Startup costs: one-time expenses to open the doors. See how much it costs to start a business.
- Sales forecast: units or clients per month multiplied by price. Show your assumptions.
- Profit and loss projection: revenue, cost of goods, gross margin, operating expenses and net profit, monthly for year one and yearly after.
- Cash flow projection: when money actually comes in and goes out, including slow-paying customers.
- Break-even point: how much you need to sell to cover all costs.
Check that your pricing leaves enough gross margin to cover overhead.
Calculate your margin9. Funding request (if you need one)
How much you need, what you'll spend it on, the type of funding you want (loan or equity), and how lenders will be repaid or investors will earn a return.
Example: an executive summary
Here's what a concise executive summary for a fictional business might look like:
BrightPaws Mobile Grooming is a Columbus, Ohio LLC offering at-home dog grooming from a fully equipped van. Our customers are busy professionals and seniors in the northern suburbs who find salon trips stressful for themselves and their pets. Interviews with 40 dog owners showed strong interest in convenience and willingness to pay a premium. We'll charge $85 to $140 per groom, targeting 6 appointments a day, 5 days a week, and reach customers through our Google Business Profile, veterinary clinic partnerships and a referral program. The founder has eight years of salon grooming experience. We are seeking a $60,000 equipment loan to purchase and outfit the van, which we project to repay within four years based on conservative bookings of 4 appointments a day.
It covers who, what, where, why customers want it, how it makes money, why the team can deliver and what funding is needed, in one paragraph.
How to build simple financial projections
You don't need complex software. A spreadsheet and clear assumptions are enough:
- Start with capacity. How many customers, units or hours can you realistically deliver each month?
- Estimate how many you'll actually sell. Start conservative and ramp up month by month.
- Multiply by your average price to get monthly revenue.
- Subtract direct costs (materials, supplies, payment fees) to get gross profit. Check margins with a margin calculator.
- Subtract operating expenses (rent, insurance, software, marketing, your pay) to get net profit.
- Map cash timing: when do customers pay you, and when do bills come due?
- Create three scenarios: conservative, expected and optimistic. Lenders take you more seriously when your plan works even in the conservative case.
Calculating your break-even point
Your break-even point is the sales level at which revenue covers all costs. The formula: fixed monthly costs ÷ gross profit per sale. If your fixed costs are $4,000 a month and each sale earns $50 in gross profit, you need 80 sales a month to break even. Every sale beyond that is profit.
A one-page business plan template
For a lean plan, answer each of these in two or three sentences:
- Problem: What problem do your customers have?
- Customer: Who exactly has it, and how many of them are there?
- Solution: What do you sell, and why is it better than alternatives?
- Competition: Who else solves it, and how are you different?
- Revenue: How do you charge, and how much?
- Marketing: How will customers find you?
- Costs: What are your startup and monthly costs?
- Milestones: What will you achieve in 30, 90 and 365 days?
- Key numbers: Which three numbers tell you it's working (for example customers, average sale, monthly revenue)?
- Funding: What do you need to get started, and where will it come from?

Business plan mistakes to avoid
- Hockey-stick projections with no explanation. Show realistic assumptions.
- "We have no competition." Lenders read this as "we didn't look."
- Vague marketing like "social media." Say which channels, how often and at what cost.
- Ignoring cash flow. Profitable businesses still fail when cash runs out.
- Writing it once and forgetting it. Revisit your plan every quarter.
Frequently asked questions
How long should a business plan be?
A lean plan can fit on one or two pages. A traditional plan for a bank or investors is typically 15 to 40 pages including financial projections.
Do I need a business plan to get an SBA loan?
Lenders usually expect a business plan with financial projections for SBA loans, especially for new businesses.
Can I write a business plan myself?
Yes. Most owners write their own. Free help is available from SCORE mentors and Small Business Development Centers, and an accountant can review the financials.
What is the most important part of a business plan?
For lenders and investors, the financial plan and the management team. For you, the market analysis: proof that customers want what you're selling.
