Writing a business plan feels harder than it should. That’s usually because founders try to write it in order, start to finish, in one sitting. It works better section by section. Each part answers a different question. And some parts are much easier to write once the others already exist. Here is the process, broken into the sections the U.S. Small Business Administration recommends for a traditional plan.
Before you start writing
First, decide which format the business needs. A traditional plan suits a founder seeking a bank loan or investor funding. A lean, one-page version suits an early idea still being tested. The steps below follow the traditional structure. A lean version simply compresses the same thinking onto a single page.
Step 1: Write the executive summary and company description
This section reads first, but it gets written last. It sums up everything else in the plan. So it’s easier to write once the rest already exists. Cover what the business does, who runs it, and what problem it solves. Keep it plain. A reader should understand the business in two or three paragraphs.
Step 2: Complete the market analysis
This section proves one thing: that the business understands its own market. It should not just assume demand exists. Name who the customers are. State how large that market is. Name who else already serves it. Skip the named competitors, and a market analysis reads as unresearched. Lenders notice that gap right away.
Step 3: Define the organization and management structure
Say who owns the business and who runs it day to day. For a single founder, this section is short. For a business planning to bring on partners or a leadership team, write this part down early. Reporting lines and ownership stakes are easier to agree on now than after a disagreement.
Step 4: Describe the product or service line
State plainly what the business sells. Say what makes it different from what already exists. Avoid vague claims like “better quality” unless something concrete backs it up, like price, speed, or materials.
Step 5: Build the marketing and sales strategy
Say how customers will actually find and buy from the business. Name real channels. That might be local advertising, a specific online platform, referral partnerships, or direct outreach. Don’t just list marketing categories in the abstract; say exactly which ones apply here.
Step 6: Write the funding request and financial projections
If the plan is being used to seek financing, state exactly how much money is needed. Say what it will be used for. Pair that with financial projections covering at least the first one to three years. This section carries the most weight with lenders. It’s where the rest of the plan gets tested against real numbers.
Step 7: Assemble the appendix
Add supporting documents that back up earlier claims: resumes, licenses, permits, or letters of reference. Not every plan needs one. But a lender reviewing a loan request usually expects it.
Traditional or lean: which to write first
Not seeking funding right away? A lean, one-page version is often the faster start. It can be expanded into a traditional plan later, once the business has real numbers to work with. For the full breakdown of both formats, see What Is a Business Plan? Definition, Purpose, and Key Sections.
FAQ
How long does it take to write a business plan?
A lean plan can be drafted in a few hours. A traditional plan, with real market research and financial projections, usually takes a few days to a few weeks. It depends on how much data needs to be gathered first.
Do I need to hire someone to write my business plan?
No. The SBA provides free templates and guidance. Most founders can write a solid first draft themselves. Professional help is more useful for polishing financial projections than for the plan’s overall structure.
Which section should I write first?
Market analysis or product description. Not the executive summary. The executive summary sums up the rest of the plan, so it’s easier to write last.
Can I skip sections that don’t apply to my business?
Yes. A single-owner service business can shorten or skip the organization and management section. The plan should match the size of the business, not a fixed template.
