How to write a business plan · plain-English guide

How to write a business plan that actually gets read.

Traditional business plans (20-40 pages, formal structure) are still required for SBA loans, some bank loans, and some grants. For everything else - VCs, internal planning, investor conversations - a one-page lean canvas plus a 10-slide pitch deck plus a financial model do more useful work. This guide covers both formats, when to use each, and what content actually moves the conversation forward.

In depth

The full picture.

01

Executive summary

First section but written last. 1-2 pages summarizing the entire plan: business name, mission, what you sell, who buys it, why you will succeed, financial highlights, what you are asking for. Most readers stop here; make it count.

02

Company description

Legal structure, location, founding date, mission, vision, values. Brief.

03

Market analysis

Industry overview, target market size (TAM/SAM/SOM), customer segments, competitive landscape, market trends. Cite real data; do not make up numbers.

04

Product or service

What you sell, how it works, pricing, why customers choose it over alternatives. Include screenshots, prototype images, or product details.

05

Marketing and sales strategy

Customer acquisition channels (paid, organic, partnerships), sales process, retention strategy, pricing model.

06

Operations plan

Where you operate, suppliers, key processes, technology stack, key partnerships, capacity constraints.

07

Team

Founders and key employees with brief bios. Highlight relevant experience. Note any gaps you are filling.

08

Financial projections

Income statement: monthly for year 1, quarterly for years 2-3, annual for years 4-5. Cash flow statement. Balance sheet. Key assumptions clearly stated. SBA loans require 3-5 year projections.

09

Funding ask

How much you need, what it will be used for (use of funds breakdown), and what you are offering in return (equity %, loan terms, etc.).

10

Appendix

Resumes, technical specs, market research, letters of intent, contracts, regulatory documentation.

FAQ

Common questions.

Do I need a business plan?
Yes if applying for SBA loan or traditional bank loan. Helpful for personal clarity. Not always required for VC (pitch deck + data room often replaces).
How long should a business plan be?
Traditional: 15-30 pages. SBA loan: 20-40 pages including financial model. Pitch deck format: 10-15 slides.
Is a lean canvas a real business plan?
Lean canvas is a 1-page strategy document, not a full business plan. Useful for early validation and personal clarity. Not sufficient for loan applications.
Should I use a template?
Yes, for structure. SBA has free templates. Score.org has industry-specific templates. Avoid templates with overly generic content; customize substantially.
How do I estimate market size?
Top-down: industry reports (IBISWorld, Statista, market research firms) for TAM. Bottom-up: addressable customers × pricing × adoption rate for SAM and SOM. Cite sources.
What financial projections do banks want?
3-5 years of monthly projections for year 1, quarterly years 2-3, annual years 4-5. Income statement, cash flow statement, balance sheet. Assumptions documented.
How accurate do projections need to be?
Reasonable assumptions, defensible logic. Banks know projections rarely match reality; they look for plausible thinking and downside scenarios.
Can I use AI to write my business plan?
For drafting and brainstorming, yes. For final document, human judgment is essential: AI-generated plans are often spotted as such and lack specific market knowledge.
How long does writing a business plan take?
First draft: 20-40 hours. Polished plan ready for lenders or investors: 80-120 hours including research and financial modeling.
