The most common mistake is writing a long plan with no reader in mind. Decide first whether this is a document to raise money, to align co-founders, or to force yourself to check whether the numbers work — then write only what that purpose needs.

Three kinds of plan

PurposeReaderWhat it must do
Financing A lender or investor Show the money can be repaid or returned, with credible numbers and named risks
Internal planning You and your team Turn intentions into targets and owners, and surface the assumptions you are betting on
Feasibility You, before committing Establish whether the unit economics work at all — often only a few pages

The standard sections

  1. Executive summary

    Written last, read first, and for many lenders the only part read closely. What the business does, who it serves, why it will work, what you are asking for and what it is for. A page.

  2. Company description

    Legal structure, location, history if any, and what problem you solve for whom.

  3. Market analysis

    Your actual addressable market rather than an industry-wide figure, the customer segments you serve, and a realistic look at competitors. A plan claiming no competition reads as inexperience.

  4. Organisation and management

    Who runs it, what they have done before, and the gaps you know you have.

  5. Products or services

    What you sell, how it is priced, what it costs to deliver, and what you charge versus alternatives.

  6. Marketing and sales

    How customers find you and how they are converted. Concrete channels, an estimate of what acquiring a customer costs, and the sales process — not a list of platforms.

  7. Funding request

    How much, what for, over what period, and on what terms you are seeking.

  8. Financial projections

    The section a lender reads properly. Covered below.

  9. Appendix

    Supporting detail — CVs, permits, letters of intent, lease terms, quotes.

The financials

Three statements, projected monthly for the first year and annually after that:

Include a break-even analysis: how much you must sell to cover fixed costs. It is a short calculation and it is often the most useful number in the document.

Assumptions are the real content

Projections are only as good as what sits behind them. State the assumptions explicitly — conversion rate, average order value, unit cost, headcount, growth — so a reader can disagree with the assumption rather than dismiss the forecast. A spreadsheet with no visible assumptions reads as invented, because it usually is.

What lenders look for

How long it should be

For most small businesses, fifteen to twenty-five pages plus appendices is ample, and a feasibility plan can be far shorter. Length is not a proxy for rigour — a tight plan with defensible numbers beats a long one padded with market research that is not about your market.

A one-page version is worth keeping alongside it. It is what you can actually talk from, and writing it exposes whether you can state the proposition clearly.

Keeping it alive

A plan written once and filed is a document; a plan revisited quarterly is a tool. Compare actuals against projections, and treat variances as information about your assumptions rather than as failures. The assumptions you got wrong are the most valuable output of the exercise.

Questions owners ask

Do I need one if I am not raising money?

Not a formal one. But the financial section — unit economics, break-even, cash flow — is worth doing regardless. It is where you find out whether the business works at the prices you intend to charge.

How far out should projections go?

Three years is standard, five for larger financing. Monthly detail for year one, annual thereafter. Beyond three years precision is theatre.

Should I use a template?

Yes, for structure — the SBA publishes free ones. Just do not let the template's section list drive how much you write. Fill what is relevant and cut the rest.
