How to write a business plan: structure, content, pitfalls

The business in brief: what is offered, for whom, why now, what it costs and what it should earn. Written last, read first. With banks, this section decides whether the rest gets read at all.

Most common mistake: a statement of intent instead of a summary. Leaving out the core figures (year 3 revenue, capital needed, break-even) reads as unprepared.

Which problem is solved, what the solution looks like in practice, and how it differs from the next best alternative. Concrete means: a layperson must be able to explain afterwards what you sell.

Most common mistake: describing the technology instead of the benefit. Customers do not buy a method, they buy a result.

Professional and commercial qualifications, relevant work experience, industry knowledge. Where there are gaps: how they get closed (training, partners, external service providers).

Most common mistake: hiding gaps. Reviewers find them anyway. A named gap with a plan looks stronger than an unmentioned one.

How big the reachable market is, who exactly the customers are, how many of them exist in your area, and where the segment is heading. Numbers with a source: national statistics offices, industry associations, chamber of commerce reports.

Most common mistake: a huge market number with no link to your own business. Splitting it into total, reachable and realistic share (TAM, SAM, SOM) exists precisely for this.

The three to five most relevant providers with strengths, weaknesses and price level, plus an honest placement of your own position. Indirect alternatives count too, including the customer solving it themselves.

Most common mistake: the sentence "we have no competition". To any reviewer it means either the market does not exist or no research was done.

Which channels bring the first hundred customers, what a won customer costs and how often they buy. Pricing strategy with reasoning belongs here, not only in the financial section.

Most common mistake: listing channels instead of costing one out. One channel with evidence beats ten mentioned.

Chosen legal form with reasoning (liability, taxes, setup cost), location in relation to the target customers, permits and required insurance.

Most common mistake: naming the legal form without reasoning. The choice shows whether liability and tax burden are understood.

Four parts belong together: capital requirement (what is needed), financing (where it comes from), profitability forecast (revenue and costs per year) and a liquidity plan (month by month, so no gap opens up). Your own cost of living belongs in there explicitly.

Most common mistake: the optimistic single case. Add a pessimistic case with roughly 30 percent less revenue. That is exactly what gets asked about in meetings.

The three biggest risks with a countermeasure each, plus a timeline with checkable milestones for the first twelve months.

Most common mistake: playing risks down. Naming and answering them reads as more credible than leaving them out.
