SaaS MVP Development Guide: Build Your First SaaS Product in 2024

Building a successful SaaS product starts with a well-architected MVP. This guide covers everything from technical architecture to pricing strategy, helping you launch your SaaS faster and smarter.

What is a SaaS MVP?

A SaaS MVP is the simplest version of your software service that:

• Solves a specific problem for paying customers
• Includes essential SaaS infrastructure (auth, billing, etc.)
• Can scale with your user base
• Generates recurring revenue

SaaS MVP vs Traditional MVP

| Aspect | Traditional MVP | SaaS MVP | |--------|-----------------|----------| | Infrastructure | Basic hosting | Scalable cloud architecture | | Payment | One-time or none | Subscription billing | | Users | Single user | Multi-tenant | | Updates | Manual | Continuous deployment | | Security | Basic | Enterprise-grade |

SaaS MVP Architecture

Multi-Tenant Architecture

Choose the right approach for your SaaS:

1. Shared Database, Shared Schema

• Simplest to implement
• Cost-effective
• Best for: Small-medium SaaS

2. Shared Database, Separate Schema

• Better isolation
• Easier compliance
• Best for: B2B SaaS

3. Separate Databases

• Maximum isolation
• Higher costs
• Best for: Enterprise SaaS
