What Is a Business Plan? Sections, Types and an Example

A business plan is a formal written document that sets out the goals of a business, the methods for reaching them, and the time frame¹. In the SBA's traditional format there are nine sections: executive summary, company description, market analysis, organization and management, service or product line, marketing and sales, funding request, financial projections, and appendix². Lenders and investors read it to decide whether to fund you. You read it first, to test the idea before you spend money.

Why you need a business plan

A plan puts on paper your product and your buyer, the money each sale brings in, and the startup cash you need. Write it before you sign a lease or order equipment. An outline with an empty competitor section or no operations section is a list of the work you have not done yet.

Three readers ask for one. A lender reads the funding request and the financial projections, and the SBA’s guidance lists what each of those sections must contain³. An investor reads the market and competition sections to judge the size of the opportunity. You read it before the first dollar goes out. If you have an idea and no numbers yet, start with a business concept and build the plan on top of it.

How a plan gets used:

Feasibility: check that one sale covers its own cost before you commit money.
Market: size the buyer group and name the competitors you will take customers from.
Milestones: set dates and numbers to measure progress against.
Funding: back a loan application or an investor meeting.
Recruiting: show a partner or first hire what the business is and where it is going.
Refocusing: re-test an existing business before you open a new location or launch a product, or before you apply for a loan.

Two formats: traditional and lean

Most business plans, as the SBA sorts them, follow a traditional format or a lean startup format³.

	Traditional	Lean startup
What it holds	Nine sections plus a five-year forecast³	Nine canvas components⁴
Main reader	Lenders, investors, partners	You and your team
Detail	Prose and financial statements	A few lines per component
Choose it when	You apply for a loan or raise money	You are still testing the idea

Lean components are key partnerships, key activities, key resources, value proposition, customer relationships, customer segments, channels, cost structure and revenue streams⁴. Add one block the canvas lacks: your key assumptions and how you will test each one. “Customers will pay this price” stays an assumption until a customer pays it.

Choose the traditional format if a lender or investor will read the plan, or if you must pay for a lease, equipment and staff before your first sale. Choose lean if you are deciding whether to pursue the idea at all. Canvas components map onto the nine traditional sections, so a lean plan expands into a full one when you need funding.

What goes in a business plan: the nine sections

For each section, the table gives one line on what to write. A full walkthrough is in the guide on how to write a business plan.

Section	What to write	Who reads it closely
Executive summary	Mission, offer, target market, your edge, team, key financials, the ask, goals tied to a number. Write it last	Every reader, first
Company description	Legal structure, owners and their stakes, the problem you solve, proof of your edge	Lenders, partners
Market analysis	Market size, number of buyers, average spend, competitors and their shares, the gap you fill	Investors
Organization and management	Org chart, résumés, key suppliers, dependence on any single platform	Lenders, investors
Service or product line	What it is, pricing, lifecycle, IP filings, supply and fulfillment	Investors
Marketing and sales	Channels, price, cost to acquire a customer (CAC), how a sale closes	Investors, you
Funding request	Amount, debt or equity, terms, time period, use of funds, future plans such as an exit³	Lenders, investors
Financial projections	Five-year forecast, monthly or quarterly in year one³	Lenders
Appendix	Licenses, leases, contracts, credit history, résumés, detailed market data	Lenders, on request

For the market section, estimate your market size with TAM, SAM and SOM and run a competitor analysis; you can close it with a SWOT table. Split the competitor part in two: a quantitative piece (who holds what share of buyer attention) and a qualitative one (what buyers complain about). Show the gap without implying there is no market.

The business plan outline puts these nine headings in a file you can fill in.

The numbers: projections and funding

Scheme of 3 parts side by side: Financial projections, The funding request, Where the money comes from — Projections say what the business earns, the funding request ties every dollar to a line in them, and the funding routes show where that money can come from.

Financial projections: time spans, unit economics, break-even

For the financial outlook, the SBA asks for the next five years and wants the first year projected by month or quarter³. NerdWallet sets the floor at three years of estimates for sales and expenses, and for the resulting profit, broken down by month or quarter⁵. If the business already runs, add income statements, balance sheets and cash-flow statements for the last three to five years³.

Your forecast rests on unit economics: what one customer brings in and what it costs to win that customer. Our check computes it with the four formulas below. These inputs come from our dog-wash example in the next section: a price of $16.50 per visit^ex, 2 visits a month^ex, a 12-month customer lifetime^ex, a margin of 0.35^ex and a CAC of $30^ex.

Quantity	Formula	Example by our method
Contribution a month per customer	price × visits a month × margin	16.50 × 2 × 0.35 = $11.55
LTV	price × visits a month × lifetime months × margin	16.50 × 2 × 12 × 0.35 = $138.60^ex
LTV to CAC	LTV ÷ CAC	138.60 ÷ 30 = 4.62^ex
Payback, months	CAC ÷ contribution a month	30 ÷ 11.55 = 2.6^ex

That $11.55 is an arithmetic step on the footnoted inputs. Of all the inputs, the margin is the weakest. The check’s own risk list says the unit economics are an estimate from a general category and were never measured in this market, so local margins could be lower^ex. A plan that carries such a number labels it as an assumption and says how it will be measured. You can swap in your own inputs in the unit economics calculator.

SBA guidance gives break-even as fixed costs ÷ (price − variable costs) = break-even point in units³. Our example has no fixed-cost figure (rent, equipment, insurance), so no break-even is computed here. Your plan needs one: total the monthly fixed costs, then divide. The break-even point and financial model pages carry the full method.

Check each projection line against a source or a comparable business. Where you have neither, mark the line as an assumption and add a low case next to it.

The funding request

Here is the SBA’s checklist for this section: the amount you need, whether you want debt or equity, the terms, the length of time the request covers, a detailed use of funds, and your future financial plans, such as an exit³. Tie every requested dollar to a line in the projections. If the request covers 18 months (an assumption for illustration), the projections show cash for those 18 months. A pitch deck carries the same ask in slide form.

Work in this order:

Outline the nine sections.
Write the text, then build the numbers.
Stress-test the numbers with a low case before anyone else reads them.

Where the money comes from

Funding routes the SBA lists⁶:

self-funding (bootstrapping);
venture capital;
crowdfunding;
bank loans;
SBA-guaranteed loans;
Small Business Investment Companies (SBIC);
Small Business Innovation Research (SBIR) and Small Business Technology Transfer (STTR) programs.

Each route has its own eligibility rules on the SBA’s site.

Worked example: a dog-wash plan, section by section

Our example idea: a self-service dog wash with grooming stations in a strip-mall unit in suburban Denver, for dog owners in apartments or condos who have no yard or tub^ex. Our method’s check gave it the verdict “Possible, with caveats”^ex and a score of 63 out of 100^ex.

Four plan sections come straight from the check’s report.

Plan section	What the check supplies	Figure (example by our method)
Market analysis	Published market size	TAM USD 2.19 billion, 2025, Mordor Intelligence^ex
Competitor analysis	Direct competitors with visibility shares	9 direct competitors^ex; top share 33%^ex
Marketing and sales	CAC and complaint themes	CAC $30^ex; 3 complaints on Quality^ex, 3 on Availability, minimum order^ex
Financial projections	The unit block	LTV $138.60^ex, LTV to CAC 4.62^ex, payback 2.6 months^ex

The competitor part of the market section lists the top five by visibility share (example by our method):

Competitor	Visibility share, %
Petco	33^ex
Lily’s Baths and Biscuits	19^ex
Pet Station	14^ex
Autowash	14^ex
Dingo’s Natural Pet Food, Self-Wash & Grooming	8^ex

The complaint counts give the offer its angle (example by our method): Quality 3^ex, Availability, minimum order 3^ex, Convenience 1^ex, Other 1^ex, Price 1^ex. The marketing section answers the two themes with 3 complaints each first.

Where a number has no source, the plan says so. No measured demand source turned up in the check (example by our method)^ex. So the plan marks demand as an assumption until it is measured, for example with a pre-launch waitlist or a count of weekend visits at a competitor.

The risks and mitigations paragraph takes the check’s four scored risks (example by our method). First, Autowash already covers about 75% of the concept in the same area, so buyers may pick the existing option (likelihood 3, impact 3)^ex; the plan answers with a feature Autowash lacks. Second, customers complain about availability and minimum orders and no competitor addresses it, but hourly stations alone may not close that gap (likelihood 2, impact 2)^ex; the plan tests booking and walk-in hours before launch. Third, the unit economics are a category estimate (likelihood 2, impact 3)^ex; the plan replaces the margin with quotes from suppliers. Fourth, the business needs a license before opening, which delays the first customer and costs money (likelihood 2, impact 2)^ex; the plan puts the license on the timeline and in the funding request. The full method for this paragraph is on business risks.

The check leaves you to write the funding request and the organization and management section, and to set your fixed costs. Those stay yours to write.

How this was made: the check ran 17 search queries^ex and read 24 sources^ex (example by our method). Every figure in this section comes from its report; the arithmetic in the unit table is ours.

Six questions before you write

Who buys, and how many of them you can reach.
Which problem they pay to solve today, and what they complain about.
Who else sells it, and what share of buyer attention each competitor holds.
What one sale earns after its direct costs.
What you need before the first customer: money, a license, a lease, people.
What could close the business in its first year.

The idea check answers questions 1 to 4 and drafts a scored risk list for question 6. Question 5 stays yours.

Common mistakes and the fix

Optimistic projections: base each line on a source or a comparable business, and add a low case.
Market figures with no source: footnote every number; where none exists, write that it is an assumption.
Summary written first: write it last, from the finished sections.
Padding: cut any paragraph that answers no question a lender or investor asks.
“No competition”: name the direct competitors and their shares, as the example does with 9 of them.
Writing alone: SCORE mentors and Small Business Development Centers offer free or low-cost counseling⁷.

FAQ

What is a business plan, in one sentence?

It is a formal written document with the goals of a business, the methods for reaching them, and the time frame¹.

How long should a business plan be?

Long enough to answer each section’s questions. A traditional plan covers nine sections and a five-year forecast³; a lean plan is short entries for nine canvas components⁴.

Do I need a business plan to get a loan?

If you apply for a bank or SBA-guaranteed loan, prepare the traditional format. The funding request names the amount you need, debt or equity, and the terms, period and use of the money³; the projections show how you will repay it.

What’s the difference between a traditional and a lean plan?

A traditional plan has nine detailed sections for lenders and investors². A lean plan fills in nine canvas components for your own decisions⁴.

How many years of projections do I need?

A five-year outlook is what the SBA advises, and it wants year one broken down by month or quarter³. NerdWallet sets the floor at three years⁵.

Where can I get free help writing one?

SCORE and Small Business Development Centers offer free or low-cost counseling through the SBA’s partner network⁷.

Should I write the executive summary first, since it opens the plan?

Fox Write it last. The summary sits first in the document, but it should come from the finished sections, because it carries your offer, target market, key financials and the ask. Writing it first usually means rewriting it when the numbers change. Finish the market and financial sections, then draft the summary from them.

My projections have unit economics but no break-even. Is that a gap?

Fox Yes, a plan needs a break-even point. Start by totaling your monthly fixed costs such as rent, equipment and insurance, then divide. The page's own example skipped it because it had no fixed-cost figure, so it computed none. Collect your fixed costs this week and add the break-even to the plan.

I cannot find any competitors for my idea. Can I write that there is no competition?

Fox Avoid writing that. The page lists "no competition" among common mistakes and says to name the direct competitors and their shares instead. If nobody sells exactly the same thing, name the closest alternatives buyers use today and show the gap without implying there is no market. Make a short list of those alternatives before drafting the section.

I have no measured demand data yet. How do I handle that in the plan?

Fox Say so plainly. The page marks demand as an assumption until it is measured, for example with a pre-launch waitlist or a count of weekend visits at a competitor. Footnote every market number, and where no source exists, write that it is an assumption. Pick one of those simple tests and put its result in the plan.

Clear and short, saved it for my next pitch.

The dog-wash example made the funding request click for me: show where each dollar goes.
Tom Walker Austin October 12, 2026
The lean format was all I needed for a first bank meeting. Good to know when the full nine sections are worth the time.
