How to write a business plan
A business plan turns an idea into a roadmap — and into the numbers a lender or investor needs to see. This guide walks through each section, what to put in it, and how to keep it short enough that you’ll actually use it.
Start lean, then expand
You don’t need 30 pages to begin. Write a lean plan first — a page that states what you sell, who buys it, what it costs to deliver, and how you make money. It forces the core logic into the open quickly. Build the full, document-style plan later, and only the sections a specific bank or investor asks for. The goal is a plan you’ll revisit, not one that sits in a drawer.
The sections of a business plan
1. Executive summary
A one-page snapshot of the whole plan: what the business does, the opportunity, your edge, and — if you’re raising money — how much and why. Write it last, but put it first; many readers decide here whether to keep going.
2. Company description
What you do, the problem you solve, your legal structure (LLC, S-corp, sole proprietor), location, and a short history or founding story. State your mission in a sentence.
3. Market analysis
Show you understand the market: its size and growth, your target customer, and your competitors’ strengths and gaps. Use real figures where you can — a believable market is what separates a plan from a wish.
4. Organization & management
Who runs the business and why they’re qualified. Include an org chart if you have a team, and call out advisors or key hires you still need.
5. Products or services
What you sell, how it benefits customers, your pricing, and where it stands (idea, prototype, shipping). Note any intellectual property or supplier relationships.
6. Marketing & sales
How customers will find you and how you’ll turn interest into sales — your channels, pricing strategy, and the steps of your sales process. Be concrete about cost per customer if you know it.
7. Funding request (if raising money)
How much you need, what you’ll spend it on, and the terms you’re seeking. Tie every dollar to a milestone so a lender can see what their money buys.
8. Financial projections
The part lenders read closest: a three-year (often five-year) profit-and-loss forecast, a cash-flow forecast, and a balance sheet. Show your assumptions — price, volume, costs — so the numbers are defensible. A break-even calculator and a ROI calculator help you sanity-check the figures, and the markup calculator helps set pricing.
9. Appendix
Supporting documents: résumés, permits, product images, detailed financial tables, and anything a reader might ask to verify.
Once you’re operating
A plan is the start; running the business is the rest. When you land clients, the invoice generator, estimate generator and time card calculator handle the day-to-day paperwork — all free and in your browser.
Frequently asked questions
What are the main sections of a business plan?
A standard business plan has nine parts: an executive summary, a company description, market analysis, the organization and management structure, your products or services, a marketing and sales plan, a funding request (if you’re raising money), financial projections, and an appendix. A lean one-page plan compresses these into key points.
How long should a business plan be?
It depends on the audience. A traditional plan for a bank or investor runs 15–30 pages; a lean startup plan can be a single page. Start lean to clarify your thinking, then expand only the sections a specific lender or investor asks for. Length matters less than clear numbers and a believable market.
Do I need a business plan to get a loan?
Usually yes. Banks and SBA lenders typically require a written plan with financial projections — a profit-and-loss forecast, cash-flow forecast and balance sheet — plus how much you need and how you’ll use it. Even when it isn’t required, the exercise forces you to test whether the numbers work.
What is the difference between a traditional and a lean business plan?
A traditional plan is detailed and document-style, best when you’re seeking significant funding. A lean plan (often a one-page canvas) covers the same logic — value proposition, customers, costs and revenue — in brief, and is faster to write and update. Many founders start lean and only build the full version when an investor or lender needs it.
