The SaaS (Software as a Service) model has revolutionized how software is delivered and monetized. If you're considering building a SaaS product, understanding the business model is crucial for success.

What Makes SaaS Different?

Unlike traditional software, SaaS offers:

  • Recurring Revenue: Predictable monthly or annual income
  • Lower Barrier to Entry: No large upfront costs for customers
  • Continuous Improvement: Regular updates and new features
  • Scalability: Serve thousands of customers with the same infrastructure

SaaS Revenue Models

1. Subscription-Based Pricing

The most common model. Customers pay monthly or annually for access. Options include:

  • Flat Rate: One price for everyone (simple but limiting)
  • Tiered Pricing: Multiple plans with different features
  • Per-User Pricing: Charge based on number of users
  • Usage-Based: Pay for what you use (API calls, storage, etc.)

2. Freemium Model

Offer a free tier to acquire users, then convert to paid. Works well when:

  • The product is easy to try
  • Value increases with usage
  • Viral/referral potential exists

Key SaaS Metrics

Track these metrics religiously:

  • MRR/ARR: Monthly/Annual Recurring Revenue
  • Churn Rate: Percentage of customers who cancel
  • LTV: Lifetime Value of a customer
  • CAC: Customer Acquisition Cost
  • LTV:CAC Ratio: Should be at least 3:1

Technical Considerations

When building your SaaS platform, consider:

Multi-Tenancy

How will you isolate customer data? Options include:

  • Shared database with tenant ID
  • Separate schemas per tenant
  • Separate databases per tenant

Scalability

Design for growth from day one:

  • Stateless application servers
  • Database read replicas
  • CDN for static assets
  • Queue-based processing for heavy tasks

Common Mistakes to Avoid

  • Underpricing your product
  • Ignoring churn until it's too late
  • Building features nobody wants
  • Not talking to customers regularly
  • Focusing on acquisition over retention
