Handbook / Starting out on your own
A one-page business plan for a business you run alone
Most business plan advice assumes you need to convince a bank or an investor. Most people who start working for themselves need to convince only one person: themselves, on a bad week three months in. A plan that fits on one page answers the questions that matter at that moment. What am I selling, to whom, for how much, and how will I know if it is working? This guide shows how to write that page.
Two formats, one purpose
SBA describes two common business plan formats. A traditional plan uses a standard structure, goes into detail in each section, takes more work and can run to dozens of pages; lenders and investors commonly ask for it. A lean plan summarises only the most important points, typically fits on one page and can take as little as an hour.
For a business of one, start lean. You can expand any section later if a lender asks. The thinking is the same; the length is not.
The nine boxes
SBA's lean format uses nine components drawn from a common business model layout. Adapted for someone working alone, they become these questions:
- Who pays? The specific kind of customer, described so you could find ten of them.
- What problem do they have? In their words.
- What do you sell? A defined service or product, with what is included.
- Why you? Experience, location, speciality, speed, or the way you work.
- How do they find you? The one or two channels you will actually use.
- What do you need? Equipment, software, skills, permits, insurance.
- Who helps? Suppliers, subcontractors, referral partners, advisers.
- What does it cost? One-time and monthly costs.
- How does money come in? Price, how often people buy, and how many sales cover your costs.
Limit each box to three lines. If you need more, you have not decided yet. That is useful information, not a failure.
A worked page
Here is an invented example for a freelance bookkeeper:
Who pays: owners of local trade businesses with one to five staff who do their own books in the evening. Problem: books fall months behind; tax time is stressful. Offer: monthly bookkeeping package: categorise transactions, reconcile accounts, monthly summary. Excludes payroll and tax returns. Why me: years of bookkeeping experience in construction firms. Channels: referrals from two accountants I know; a local trades association. Needs: accounting software subscriptions, professional liability insurance, a secure file system. Help: two accountants for tax returns and referrals. Costs: small one-time setup; monthly software, insurance and phone. Money in: fixed monthly fee per client; the number of clients needed to cover costs and my target pay is written on the startup sheet.
That page tells the owner what to do on Monday: call the two accountants and the trades association.
Make the numbers honest
The money box is where one-page plans most often go vague. Put real figures in it:
- your monthly business costs
- the hours per week you can sell
- the price per hour, job or month
- how many sales a month cover costs and pay you
The site's startup sheet and quote floor calculator help with the arithmetic. If the number of sales needed is higher than you can realistically win or deliver, the plan has already done its job: it shows that the price, the costs or the offer must change.
Mark what you do not know
Every early plan is mostly assumptions. Mark each one. "Owners will pay a monthly fee" is an assumption until someone does. SBA's guidance on market research suggests gathering information about customers, competitors and demand; for a one-person business the fastest research is usually a direct conversation with a likely buyer.
Pick the riskiest assumption and decide how to test it this month. The guide on testing a business idea gives methods.
When you need the long version
Write a traditional plan when:
- you are applying for a loan or grant that requires one
- you are bringing in a partner or investor
- the business involves significant money up front, such as equipment, premises or stock
Even then, the one-page plan is a good outline. Each box becomes a section.
Keep it alive
A plan is worth reading only if it is current. Pin it near where you work, reread it monthly, and rewrite it when the facts change. In the first year, you will probably rewrite the "who pays" and "money in" boxes several times. That is the plan working.
One page, nine boxes, real numbers and a reminder to revise it: that is a business plan you will actually use.
Questions people ask
What is the difference between a lean plan and a traditional plan?
SBA says traditional plans use a standard structure with detail in each section and are commonly requested by lenders and investors, while lean plans summarise only the most important points, are typically one page, and can take as little as an hour.
Will a bank accept a one-page plan?
Usually not on its own for a loan. SBA notes lenders and investors commonly request the traditional, detailed format. The one-page plan is a good first draft of the thinking that a longer plan expands.
How often should I update it?
Whenever something important changes, and at least every few months in the first year. The value of a short plan is that updating it takes minutes.
Should I include income projections?
Include the numbers you control and can check: costs, prices, hours available and how many sales cover your costs. Avoid optimistic revenue forecasts you cannot support.
Do this week
- Copy the nine headings from this guide onto one page and fill each with no more than three lines.

- Put a number in the money box: your monthly costs and the price you plan to charge.
- Pick one assumption on the page to test this month and write how you will test it.
- Put a calendar reminder to reread and revise the page in ninety days.
