The short answer
Use a lean (one-page) plan if you want to start quickly, your business is fairly simple, or you expect to change the plan often. Use a traditional plan if you are asking a bank or investor for money or want a detailed roadmap. The SBA notes that lenders and investors commonly request the traditional format.

What a lean plan includes
The SBA lists nine components:
- Key partnerships: suppliers, manufacturers, subcontractors
- Key activities: how you gain an edge
- Key resources: staff, capital, skills, intellectual property
- Value proposition: the unique value you bring
- Customer relationships: how customers deal with you
- Customer segments: exactly who you serve
- Channels: how you reach customers
- Cost structure: your biggest costs
- Revenue streams: every way you make money
What a traditional plan includes
The SBA describes nine common sections:
- Executive summary
- Company description
- Market analysis
- Organization and management
- Service or product line
- Marketing and sales
- Funding request (only if you need money)
- Financial projections
- Appendix
You don’t have to use every section: the SBA says to use the ones that make sense for your business.
A practical approach
Many founders start with a lean plan, test the idea with real customers, then expand it into a traditional plan when they need funding. Our template lets you switch between both; your text is saved separately for each format.

Is a one-page business plan enough?
For many small businesses starting with their own money, yes. If you apply for a loan or investment, expect to be asked for more detail.
How long should a business plan be?
A lean plan is usually one page. A traditional plan can run to dozens of pages, but shorter and clearer is better than long and vague.
What is the most important section?
For lenders, usually the financial projections and funding request. For you, the customer and market sections matter most, because they tell you whether the business can work.
