The B2B Business Plan as Code: A Forkable Template for SaaS Founders

#ai #automation #n8n #developer

You can architect a scalable microservices backend in your sleep, but the thought of writing a business_plan.docx file probably gives you anxiety. I get it. Traditional business plans feel like monolithic legacy code—verbose, rigid, and disconnected from how we actually build things.

But what if we treated a business plan like code? What if it were a modular, logical, and executable spec for your company? A well-structured business plan is just that: the architectural blueprint for your venture. It's the README.md that convinces investors to contribute to your repo.

Today, we're deconstructing the business plan monolith and refactoring it into a clean, dev-friendly format. Plus, I'm giving you a free B2B business plan template you can fork and use immediately.

Deconstructing the Monolith: Core Modules of a Business Plan

Forget the 50-page Word doc. A modern SaaS business plan is a collection of interconnected modules. Think of them as microservices, each with a specific job.

  • Executive Summary (README.md): A high-level overview. What's the project, who is it for, and what problem does it solve? This is your elevator pitch.
  • Problem & Solution (./src/core/): The core logic. What's the critical pain point you're solving (the bug), and how does your product provide the elegant fix?
  • Market Analysis (./utils/marketValidator.js): Defines the environment. Who are the users? Who are the existing players (competitors)? How big is the Total Addressable Market (TAM)? Is there a valid API (market) for your solution to plug into?
  • Product & Roadmap (./features/): The technical spec. What have you built (MVP), and what's in the pipeline? Detail your tech stack, key features, and future sprints.
  • Go-to-Market Strategy (deploy.sh): Your deployment script. How will you launch and distribute your product? Think beta lists, developer communities, content marketing, and API integrations.
  • Financial Projections (./monitoring/billing.js): Your resource allocation and performance metrics. This covers pricing, server costs, Customer Acquisition Cost (CAC), Lifetime Value (LTV), and your burn rate.

The "Business Plan as Code" Approach: A Practical Example

Let's turn these abstract modules into something tangible. The best way to build a robust SaaS business plan is to define your variables and functions clearly.

### Define Your User Persona: The API Consumer

Before you write a single line of your product's code, you need to know who you're building for. In a business plan, this is your Ideal Customer Profile (ICP) or user persona. Instead of a vague paragraph, define it as a JSON object. This is a great business plan example that investors will appreciate.

const idealCustomerProfile = {
  "companyName": "ScaleUp AI",
  "industry": "Machine Learning Operations (MLOps)",
  "size": "50-200 employees",
  "title": "Lead DevOps Engineer",
  "name": "Aisha Kumar",
  "goals": [
    "Reduce CI/CD pipeline failures by 30%",
    "Automate infrastructure provisioning",
    "Improve model deployment monitoring"
  ],
  "painPoints": [
    "Manual environment configuration is error-prone",
    "Lack of visibility into deployment costs",
    "Toolchain is fragmented and complex"
  ],
  "technicalStack": ["Kubernetes", "Terraform", "AWS", "Python", "Jenkins"]
};

### The Metrics Endpoint: Calculating Key Financials

Investors want to see that you understand the mechanics of a SaaS business. You don't need a complex spreadsheet to start. You just need to show the core logic. Writing a simple function to calculate LTV (Lifetime Value) demonstrates you get the unit economics.

// A simplified function to calculate Customer Lifetime Value (LTV)
function calculateLTV(monthlyRecurringRevenue, customerChurnRate, grossMargin) {
  // ARPA: Average Revenue Per Account (per month)
  const ARPA = monthlyRecurringRevenue;

  // Customer Lifetime (in months) = 1 / Churn Rate
  const customerLifetime = 1 / customerChurnRate;

  // LTV = (ARPA * Customer Lifetime) * Gross Margin
  const LTV = (ARPA * customerLifetime) * grossMargin;

  return {
    ltv: LTV.toFixed(2),
    customerLifetimeInMonths: customerLifetime.toFixed(1)
  };
}

// Example usage:
const mySaaSMetrics = calculateLTV(299, 0.04, 0.85); // $299/mo, 4% monthly churn, 85% margin

console.log(`Customer LTV: $${mySaaSMetrics.ltv}`); // Expected output: Customer LTV: $6353.75
