How Do I Write a Business Plan?

A business plan is a clear, convincing story about what you’re building, for whom, how it makes money, and why it will work. Think of it as a decision-making tool first, and a fundraising document second. Below is a practical, step-by-step guide with structure, prompts, and formulas you can copy into your own doc.

Start Here: Pick Your Plan Type

Lean 1–2 page plan (internal use / early stage): fast, highlights assumptions and milestones.
Standard plan (banks, investors, partners): 10–20 pages plus financial model.

When in doubt, draft the lean plan first, then expand.

A One-Page Lean Plan (Copy/Paste Template)

Problem

Who has the problem?
What’s the pain, how urgent, what alternatives do they use today?

Solution

Your product/service in one sentence.
3–5 key features or outcomes.

Customer & Market

Ideal customer profile (ICP).
Market size (TAM/SAM/SOM) quick estimate.

Business Model

Pricing, average order value (AOV) or ARPU, gross margin target.

Go-to-Market

Top acquisition channels (e.g., SEO, outbound, retail).
Sales motion (self-serve, inside sales, partnerships).

Unfair Advantage

IP, data, distribution, expertise, timing, brand.

Milestones & KPIs (next 12 months)

e.g., MVP by Q1, first 50 customers by Q2, $X MRR by Q4.

Team

Founders, key roles to hire, advisors.

Financial Snapshot

12-mo revenue/expense summary, burn, runway.

Funding (if applicable)

How much you’re raising and use of funds.

The Standard Business Plan: Section-by-Section

1) Executive Summary (write last, place first)

What you do: one-sentence value proposition.
For whom: target customer.
Traction: proof points (users/revenue/pilots).
Why now: market shift or enabling tech.
Ask: loan amount / investment round and use of funds.
Tip: keep it to ½–1 page; every sentence should earn its place.

2) Company Overview

Legal structure, location(s), founding date.
Mission and vision (concise).
Product(s)/service lines and current status (idea, MVP, launched).

3) Market & Customer

ICP: industry, size, budget, decision-maker.
Market size:
- TAM (entire market), SAM (you can serve), SOM (you can capture in 3–5 years).
- Use bottom-up math: customers × price × penetration.
Competitive landscape: direct, indirect, substitutes; your differentiation matrix.

4) Problem & Solution (Product)

Customer pain points backed by quotes, usage, or data.
Your solution, core benefits, and how it’s better/different.
Roadmap (what’s live vs. planned). Include IP/status (patents, trade secrets).

5) Business Model & Unit Economics

Pricing packages, expected ARPU/AOV.
Cost of goods sold (COGS) and gross margin target.
Unit economics quick sheet:
- CAC = Sales & Marketing Spend ÷ New Customers.
- LTV = ARPU × Gross Margin % × Average Customer Lifetime (months) ÷ 12.
- Payback Period (months) = CAC ÷ (ARPU × Gross Margin %).
- Aim for LTV:CAC ≥ 3:1 and payback ≤ 12 months (varies by industry).

6) Go-to-Market Strategy

Channels (paid, organic, partnerships, events, outbound).
Funnel targets: impressions → leads → SQLs → wins (with conversion assumptions).
Sales process and roles; partner strategy; onboarding and activation.

7) Operations Plan

Key processes: procurement, production/fulfillment, quality control, customer support.
Suppliers and dependencies; SLAs.
Facilities, equipment, inventory approach (e.g., JIT).
Systems stack (POS/ERP/CRM/helpdesk).

8) Team & Org

Founders’ relevant experience (what makes you the team to win).
Current team and gaps; hiring plan and org chart.
Advisors/board and how they add value.

9) Financial Plan (3–5 Years)

Include an Income Statement, Cash Flow, and Balance Sheet with monthly detail for Year 1 and annual thereafter. Add a driver-based model:

Revenue model:
- Volume × Price (by product/segment).
- Seasonality assumptions if relevant.
COGS: materials, labor, logistics → Gross Margin.
Operating expenses: R&D, S&M, G&A (headcount-driven).
Capex & depreciation; working capital (AR, AP, inventory days).
Funding plan: equity/loans, interest, covenants.
Scenarios: Base, Upside (+20% volume), Downside (–20% volume/CAC +20%).
Break-even: Fixed Costs ÷ Contribution Margin %.
Runway: Cash on Hand ÷ Monthly Net Burn.

10) Funding Ask & Use of Funds (if applicable)

Amount, instrument (equity/SAFE/loan), target close date.
Allocation: % to product, GTM, ops, hiring, working capital.
Milestones this capital unlocks.

11) Risks & Mitigations

Top 5 risks (market, product, regulatory, supply, key-person).
Mitigations and early warning indicators (KPIs).

12) Milestones & KPIs

Timeline with quarterly goals.
Core KPIs: revenue/MRR, gross margin, CAC, LTV, churn/retention, NPS, on-time delivery, inventory turns—pick the 5 that matter most.

13) Appendix

Detailed research, surveys, letters of intent, technical specs, resumes, legal docs, permits, certifications, credit references.

Research: How to Build Credible Numbers

Talk to customers: 10–20 interviews beat desk research. Capture quotes.
Use bottom-up sizing: count real buyers and realistic share; avoid “1% of a giant market.”
Triangulate: blend public reports, competitor pricing pages, and your tests/pilots.
Benchmark: margins, CAC, payback from comparable companies or industry reports.

Writing Tips That Impress Lenders & Investors

Keep it clear and scannable: headings, bullets, charts; avoid jargon.
Evidence over adjectives: show pilots, revenue, waitlists, or letters of intent.
Consistency: every claim should reconcile with the financial model.
Length: 10–20 pages plus model is plenty for most small/mid businesses.
Use visuals: competitor matrix, funnel chart, P&L summary, roadmap.
Customize the emphasis:
- Banks: cash flow, collateral, repayment.
- Investors: growth, team, market, moat.
- Partners: reliability, SLAs, mutual upside.

Common Mistakes (and Easy Fixes)

Vague audience: Define ICP; name 3 example customers.
Top-down market sizing only: Add bottom-up math.
Hope as a strategy: Replace with a GTM funnel and conversion goals.
Unrealistic margins: Show COGS drivers and benchmarks.
No sensitivity analysis: Include upside/downside cases.
Ignoring cash: Profitable ≠ cash-positive; model AR/AP and inventory.
