How to Write a One-Page Business Plan That Actually Gets Used

Nine questions on one page, reviewed quarterly. The thirty-page version exists to satisfy a bank, and nobody has ever reread one.

By Tariq Sallam·September 2026

I have written long business plans and I have never once reread one. They are documents produced for an audience, usually a lender, and their length is a function of that audience rather than of usefulness.

What I do use is one page, nine questions, revisited every quarter. It fits on a screen, it takes an hour to write, and because it is short it stays current.

Quick Info

Length
One page. If it does not fit, it is not decided
Time to write
One to two hours
Review cadence
Quarterly, with the numbers in front of you
What it is for
Making decisions, not raising money
When you need the long version
A bank loan, investors, or a grant application
Most important question
Who is it for, specifically

The nine questions

Answer each in one or two sentences. If an answer needs a paragraph, you have not decided yet, and that is useful to notice.

01What do we sell? In plain words a customer would use.
02Who is it for? Specific enough to name actual examples. "Small businesses" is not an answer.
03What problem does it solve, and what does that problem cost them now?
04Why us rather than the alternatives, including doing nothing?
05How do customers find us? Name the two channels you will actually work.
06What does it cost and what is the margin?
07What is the one number that tells us it is working?
08What is the biggest risk, and what would we do about it?
09What are we deliberately not doing this year?

That last question is the one people leave out and the most valuable one on the list. A plan that does not exclude anything does not guide any decisions.

How to answer the hard ones

Who is it for

Narrow until you can name three real businesses or people who fit. If you cannot name them, the definition is too wide to market to. "Independent dental practices in West Yorkshire with two or more surgeries" is a target. "SMEs" is a hope.

Why us

Not "quality and service", which everybody claims. Something a competitor would find awkward to say: a specialism, a guarantee, a price structure, published outcomes, a genuine constraint you accept that others do not.

The one number

One. Not a dashboard. New customers per month, or monthly recurring revenue, or qualified enquiries. The number that, if it moves in the right direction for a year, means the business worked.

If you cannot name the single number that would tell you the year went well, you will spend the year busy and unable to say whether it worked.

Add the numbers, briefly

Four figures, not a financial model. On the same page.

Revenue target for the year, and what it means monthly.
Fixed costs per month.
The number of customers or projects required to hit the target.
Cash reserve position and target.

Then sanity-check the arithmetic. If the target requires forty projects and you can deliver twenty, the plan is wrong now rather than in November. This one check has saved more of my clients from a bad year than anything else on the page.

The quarterly review

This is what makes it a plan rather than a document. Ninety minutes, four times a year, with the actual numbers in front of you.

01What did the one number do?
02Which answer on the page turned out to be wrong?
03What did we do that was not on the page, and should it be?
04What is the biggest risk now? It changes.
05What are we stopping this quarter?
06Rewrite the page. It should look different every quarter.

The rewriting matters. A plan that has not changed in a year is either a very stable business or an unread document, and it is usually the second.

When you do need the long version

A bank loan, which requires a specific format including financial projections.
Investors, who want a market analysis and a model.
Grant applications, which have their own templates.
A partnership or shareholder agreement, where the detail is the point.
In each case, write the long version for that audience and keep the one-pager for yourself. They are different documents with different jobs.

Do not confuse the two. A funding document is a persuasion exercise; a plan is a decision tool. Trying to make one document do both produces something you neither believe nor reread.

What to leave out

Mission and vision statements. If they do not change a decision, they are decoration.
Five-year projections. Nobody can forecast a small business three years out and pretending otherwise wastes an afternoon.
Market size figures from an industry report. Your addressable market is the people you can actually reach.
SWOT analysis, unless it produces an action. Usually it produces a list.
Anything you would be embarrassed to be held to. If you do not believe it, it does not belong on the page.

A worked example, compressed

To show the level of specificity that makes it useful.

Sell: SEO and website work for independent healthcare practices.
For: dental and veterinary practices with two to five sites, in Yorkshire.
Problem: they are invisible in local search and lose patients to corporate groups. Each lost patient is worth roughly £400 a year.
Why us: we only work with healthcare practices and publish our results.
Found via: local search for our own service terms, plus referrals from practice management consultants.
Price: £1,200 a month retainer, 70% gross margin.
One number: retained clients, target twelve by December.
Biggest risk: dependence on referrals from two consultants. Mitigation: publish two case studies a quarter to build inbound.
Not doing: e-commerce work, paid social, one-off projects under £2,000.

Nine lines, and every one of them would settle an argument about what to do next week. That is the whole point.

Write it this afternoon

01Answer the nine questions in a document, one or two sentences each.
02Add the four numbers and check the arithmetic works.
03Cut anything you do not believe.
04Put it somewhere you will see it, not in a folder.
05Diarise the quarterly review now, all four dates.
06Then use it: next time you are offered work outside the page, that is the decision it exists to make.

Frequently Asked Questions

Is a one-page business plan enough?

For running the business, yes. For a bank loan, investors or a grant, you need their format as well, written for that audience.

What should a one-page plan include?

What you sell, who for, the problem, why you, how customers find you, pricing and margin, one key number, the biggest risk, and what you are not doing.

How often should I review it?

Quarterly, for ninety minutes, with the real numbers in front of you. Rewrite the page each time.

Do I need financial projections?

Four figures: revenue target, fixed costs, customers required and cash reserve. Five-year projections for a small business are guesswork.

Why include what you are not doing?

Because a plan that excludes nothing cannot guide a decision. The exclusions are what make it useful when opportunities appear.

What if my answers change completely?

That is the plan working. A page that looks the same after a year is usually one nobody read.

Before You Go

Nine questions, four numbers, one page, reviewed quarterly. It takes an afternoon and it is the only planning document I have ever used more than once.

The exclusions are the part that earns its keep. Validation comes before the plan; cash flow is what turns it into a working month.

Nine questions. One page. Rewrite it quarterly.
