# Writing a business plan

**Source and license:** U.S. Small Business Administration (SBA), "Write your business plan", [sba.gov/business-guide/plan-your-business/write-your-business-plan](https://www.sba.gov/business-guide/plan-your-business/write-your-business-plan). Public domain (US government work); acknowledged here as SBA asks. This page is an AI-assisted summary by iinventedlight in its own words.

## Summary
A business plan is the roadmap for starting, running and growing a business, and the tool for convincing lenders, investors or partners. SBA describes two common formats. A traditional plan is long and detailed and is what lenders and investors usually ask for. A lean startup plan is a one-page chart of the key elements that can be written in about an hour. Use the sections that fit your business rather than a fixed outline.

## Facts
- id: F1
  claim: A traditional plan uses a standard structure, goes into detail in every section, takes more upfront work and can run dozens of pages. Lenders and investors commonly request it, so it suits people seeking traditional financing or wanting a full plan.

- id: F2
  claim: A lean startup plan summarizes only the key elements, usually on one page, and can take about an hour. It suits a simple business, a quick start, or a plan you expect to revise often. Some lenders and investors may ask for more.

  claim: The executive summary says briefly what the company is and why it will succeed, with the mission, the product or service, and basic facts on leadership, staff and location. Add financial information and growth plans if you are seeking financing.

  claim: The service or product line section explains what you sell, how it helps customers, its lifecycle, any copyright or patent plans, and any research and development. Marketing and sales explains how you will attract and keep customers and how a sale actually happens.

  claim: A funding request states how much money you need over the next five years, debt or equity, the terms you want, the period covered, and exactly what the money will pay for, plus longer-term financial plans such as paying off debt or selling the business.

  claim: Financial projections back up the funding request. An existing business includes three to five years of income statements, balance sheets and cash flow statements. Every plan forecasts the next five years, with quarterly or monthly detail for the first year, matched to the funding request.
