Writing a Business Plan? Here’s What You Should Know First

Before writing a business plan, understand this: a plan is not a formality you rush through to impress a bank or an investor, it is the roadmap that forces you to think clearly about whether your idea will actually make money in Kenya’s market. Get the thinking right first, and the document almost writes itself.

What is a business plan actually for?

Most people assume a business plan exists only to secure a loan. That is one use, but it is not the main one.

The real purpose is clarity for you. It answers the questions that keep founders awake at night. Who is my customer? How much will I charge? How long before I break even? If you cannot answer those on paper, you are gambling, not planning.

Banks like KCB and Equity, along with grant programs and SACCOs, will ask for one. But even a mama mboga scaling into a mini-supermarket benefits from writing things down.

Do I really need a formal 40-page document?

No. This is where many aspiring founders get stuck and never start.

A tight 5 to 10 page plan beats a bloated one nobody reads. If you are applying for funding, follow the lender’s format. If you are planning for yourself, a lean one-page canvas is often enough to begin.

What matters is honesty, not length. A plan full of hopeful numbers you invented will fail the moment reality hits. Keep it short, keep it truthful, and update it as you learn.

How do I know my numbers are realistic?

This is the part people fake, and it is the part that sinks businesses.

Start with real costs. If you are opening a small eatery in Nairobi, price out rent (say KES 40,000 a month), a business permit from the county, food supplies, and staff wages. Then estimate honest daily sales, not your dream sales.

Research the market before you write. Register properly through the Business Registration Service (BRS) and check the licensing requirements for your county early, because permits and compliance costs surprise many new owners.

Do the maths twice. If your break-even point is 18 months away, you need enough capital to survive that stretch.

Common mistakes that make a business plan useless

The biggest one is copying a template blindly. A plan built for a tech startup in Silicon Savannah will not fit a boda boda spare parts shop in Nakuru.

Other traps to avoid:

• Ignoring competition. Somebody is already serving your customer. Know them.
• Underestimating cash flow. Profit on paper means nothing if you cannot pay suppliers this month.
• Forgetting M-Pesa float, till fees, and mobile money transaction costs, which quietly eat into margins.
• Writing what investors want to hear instead of what is true.

A plan is a tool for making decisions, not a marketing brochure for yourself.

Where does technology fit into your plan?

Smart founders now use digital tools to plan faster and cheaper. Free spreadsheet templates, mobile accounting apps, and even AI drafting tools can save you hours.

If you are comfortable using AI to speed up written work, the same caution we shared in our guide on writing a resume using AI applies here: let it assist, but never let it replace your own judgement about your business.

Also plan for the paperwork side of running a business. Just as you would prepare early for official documents like a birth certificate in Kenya, sort out your registration, KRA PIN, and permits before you launch, not after.

A quick note on money decisions

A business plan involves financial projections and risk. Treat the numbers as estimates, not promises. Before you take a loan or commit your savings, speak to a qualified accountant or a business advisor who understands your sector. A one-hour consultation can save you from a costly mistake.

The bottom line before you start writing

Writing a business plan is really about answering one question honestly: will this make money, and how? Keep it short, base it on real Kenyan costs, and be ruthless with your own assumptions.
