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?
Not always a formal one, but you need clarity on your market, model, and finances, and a written plan helps if you seek a loan, investors, or partners, or want to pressure-test your idea. For a simple business, a lean one-page plan often suffices. We handle the legal formation so you can focus on the plan and the business.
What goes in a business plan?
Typically an executive summary, a description of the business and market, your product or service, marketing and operations plans, the team, and financial projections, scaled to your purpose. A lender or investor wants the financials and market; a personal roadmap can be lighter. We keep the entity setup handled while you build it.
How detailed should my financial projections be?
Detailed enough to be credible: revenue assumptions, costs, cash flow, and a break-even, grounded in real numbers rather than hopeful ones, since lenders and investors probe them. Overly rosy projections undermine trust. We keep your entity and books structured so real numbers are easy to pull as you build projections.
Do I need a business plan to get a loan?
Usually yes: banks and SBA lenders typically want a business plan with financials to evaluate a loan, and a strong plan improves your odds and terms. We keep the entity, EIN, and compliance in order so the business side of the application is solid.
Should I form my business before or after the plan?
They go together: you can draft the plan first, but forming the entity is what lets you open banking, sign contracts, and appear as a real business to lenders and partners. We form it quickly so the plan has a real company behind it.
How long should a business plan be?
It depends on the audience: a lean plan for yourself can be a page or two, while a lender or investor plan is usually longer with full financials. Length is not the point; clarity and credible numbers are. We handle the formation so you can focus on making the plan clear rather than padding it.
Can a business plan help me test my idea?
Yes: writing it forces you to think through your market, costs, and model, often surfacing gaps before you spend money, which is valuable even if no one else reads it. We keep the setup lightweight so you can validate the idea before committing to the full build-out.
Do I need projections for an LLC or just a corporation?
Neither entity type requires a business plan or projections to exist, so this is about your goals, funding, and clarity, not a legal requirement. We form whichever entity fits your plans and leave the planning to you, with the legal foundation handled.
Can File.Business help me start the business?
We handle the legal foundation, forming the entity, obtaining the EIN, providing the agent, and setting up compliance, so once your plan is ready you have a real, compliant company to execute it through rather than a document without a business behind it.
