How to write a business plan, step by step

To write a business plan, work through seven standard sections: an executive summary, company description, market analysis, organization and management, product or service, marketing and sales, and financial projections. Write the executive summary last. A typical plan runs 15 to 25 pages, or a one-page lean canvas for a quick start.

The standard business plan sections

A conventional plan includes: executive summary, company description, market analysis, organization and management, products or services, marketing and sales strategy, funding request if you are raising, and financial projections. Not every plan needs every section, but investors and lenders expect this structure.

Start with the market, finish with the summary

Write the executive summary last, even though it appears first, because it distills the rest. Begin instead with market analysis - defining your customer, market size, and competitors - since everything else depends on knowing who you serve and how big the opportunity is.

Make the financials realistic

Lenders and investors scrutinize the numbers. Include a sales forecast, an expense budget, cash flow, and a break-even point, with assumptions you can defend. Conservative, well-reasoned projections build more credibility than hockey-stick growth you cannot justify.

How long should a business plan be?

A traditional plan is usually 15 to 25 pages plus appendices. If you need to move fast or are testing an idea, a one-page lean plan covering problem, solution, market, and model is a valid starting point you can expand later.

A faster way to draft it
