The Complete Guide to Writing a Business Plan Investors Will Actually Read

Most business plans that land in an angel investor's inbox in Lagos or Abuja open with a description of the product. That is the wrong place to start. An investor reading their fortieth plan of the month wants to know, within the first paragraph, what painful, expensive, or time wasting problem you are solving and for whom. Write one page that states the problem in plain terms, backed by a real example. If you are building a logistics app for market traders in Onitsha, describe what a trader currently loses each week to spoilage, theft, or unreliable transport, and put a naira figure on it if you can. Pull that figure from a conversation with an actual trader, not a guess. Investors can tell the difference between a founder who has spoken to fifty potential customers and one who has spoken to five friends. Then state, in one sentence, who feels this problem most acutely. "Small retailers in secondary markets across the South East" is more useful to an investor than "Nigerian businesses," because it tells them you understand your first customer well enough to go and find them. This section should be short, no more than 300 words, because its only job is to earn the right to be read further. If the problem is not urgent, specific, and believable, nothing else in the plan will save it.

The executive summary sits at the front of the document but should be the last thing you write, because it is a compressed version of everything that follows. It should run no longer than one page and answer five questions in order: what problem you solve, how you solve it, how big the opportunity is, how you make money, and how much you are raising and for what. A common mistake founders make is treating the executive summary as marketing copy, full of adjectives like "revolutionary" or "disruptive." Investors read those words as a warning sign that the plan lacks substance underneath. Replace adjectives with numbers wherever possible. Instead of "we have seen incredible early growth," write "we grew from 40 to 260 paying users between January and June, with monthly revenue rising from ₦180,000 to ₦1.4 million." Close the summary with your ask: the amount you want to raise, in naira, and the three or four things that money will unlock, such as a new warehouse in Kano or six months of working capital for inventory. Many Nigerian investors, whether angel networks, family offices, or development finance funds like BOI, decide within the first page whether to keep reading. Treat this page as the whole pitch compressed, and everything after it as the evidence that backs it up.

A market size slide built entirely on a global report, without a single Nigerian data point, tells an investor you have not done the work locally. Start with data from the National Bureau of Statistics, SMEDAN, or a relevant sector body, and build your market size from the bottom up rather than the top down. Bottom up means starting from your actual customer: how many market traders operate in Onitsha and similar hubs, how much each one might reasonably pay per month, and what that adds up to. This is far more convincing than quoting a Nigeria wide ecommerce figure and assuming you will capture one percent of it, a method investors have learned to distrust because it can justify almost any business. Break the market into three layers: the total market, the segment you can realistically reach given your current model and geography, and the customers you can serve in the next twelve to eighteen months. Reference the currency reality too. If your business is exposed to forex volatility, whether through imported inventory or dollar denominated software costs, say so directly and explain how you plan to manage that exposure. Investors in Nigeria have seen too many plans ignore this to trust one that does not address it head on.

Your financial model does not need twenty tabs of spreadsheet wizardry. It needs three things: a revenue build that shows your assumptions clearly, a cost structure that reflects Nigerian realities like generator fuel, data, and rent, and a cash flow projection for at least eighteen months. State your assumptions in plain language before the numbers. If you assume 15 percent month on month growth in customers, say why, based on what you have already seen or what comparable businesses in similar markets have achieved. An investor will ask you to walk through these assumptions live, so build the model yourself rather than outsourcing it entirely to a consultant you cannot explain it without. Include a break even analysis showing the point at which revenue covers your fixed and variable costs. Nigerian investors are especially attentive to burn rate and runway, given how expensive it can be to raise a follow on round if a company runs out of cash. Show your monthly burn, your current cash position, and how many months of runway your requested raise buys you. Where relevant, note your tax position too, including VAT at 7.5 percent and your Companies Income Tax obligations to FIRS, since a plan that ignores tax planning reads as one written by someone who has not yet operated a real, compliant business.

Investors back people as much as ideas, particularly at the earliest stages where the product will inevitably change. Use this section to explain, honestly, why your specific team is positioned to solve this specific problem better than a well funded competitor could. For each founder, include relevant experience, whether that is years spent in the industry, a previous business built and sold, or direct personal experience with the problem. If your co founder ran a distribution business in Kano for eight years before this venture, that detail matters more than a generic line about being "passionate." Be honest about gaps too. If you do not yet have a technical co founder, say what you are doing about it, whether that is an advisor, a fractional CTO, or an active search backed by a named recruiter. Investors respect founders who name their weaknesses and show a plan to address them far more than those who pretend the team is complete when it clearly is not. Include an advisory board if you have one, especially names with credibility in Nigerian finance, retail, or the specific sector you operate in, since a respected advisor can substitute for experience the founding team has not yet accumulated.

Vague fundraising asks kill otherwise strong plans. State the exact amount you are raising, the instrument (equity, convertible note, or SAFE), and the valuation or discount terms if you have already set them. Then break down, in a simple table, exactly how the money will be spent: inventory, hiring, marketing, technology, and working capital, each with a naira figure and a percentage of the total. Tie each spending category back to a milestone. "₦8 million for inventory to support expansion into two new markets by month nine" is far more convincing than "₦8 million for inventory." Investors want to see a direct line between the money and the growth it produces, because that line is what determines whether your next round will be easier or harder to close. Address dilution and prior fundraising honestly. If you have raised a friends and family round already, disclose the amount, the terms, and how much of the company that round represents. Nigerian investors talk to each other, and a plan that surfaces this information voluntarily builds more trust than one that leaves it to be discovered during due diligence. Close this section with a short note on your planned next round, showing you are thinking two steps ahead rather than treating this raise as a one time event.

The best written plan in the world will still lose an investor's attention if it is a dense wall of ten point text. Most investors skim before they read, so structure the document for that reality. Use clear headers, short paragraphs, and one chart or table per key claim rather than paragraphs of numbers. Keep the full written plan to somewhere between ten and fifteen pages, and build a separate ten slide summary deck that can stand on its own in an email. Many investors will only ever look at the deck, and will request the full plan solely if the deck earns a second meeting. Both documents should tell the same story with the same numbers, since inconsistency between them is one of the fastest ways to lose credibility during diligence. Finally, proofread relentlessly and have at least one person outside your company read it cold. A plan with typos, inconsistent figures between pages, or currency symbols used inconsistently signals a lack of attention to detail that investors will assume carries over into how you run the business. Save the final version as a PDF, name the file professionally with your company name and date, and send it as a proper attachment rather than a shared link that requires extra clicks to access.
