The wrong question
Most founders ask: "Should I build a SaaS or a web app?"
That's the wrong question. The right question is: "What do I need to learn first?"
When you need SaaS
Build SaaS if:
- You're selling software to many customers as a recurring product
- Each customer needs their own isolated data
- You want to charge subscription fees
- You're building a product, not a service
SaaS is fundamentally a product business — not a service business with software attached.
When you need a custom web app
Build a web app if:
- You're solving one specific business problem (yours or one client's)
- You need internal tools for your team
- You're delivering a custom solution — not a mass product
- Time-to-market matters more than long-term scalability
The trade-offs
| Factor | SaaS | Custom Web App |
|---|---|---|
| Initial cost | Higher (AED 25k+) | Lower (AED 15k+) |
| Time to launch | 8-12 weeks | 4-8 weeks |
| Revenue model | Recurring | One-time |
| Complexity | Multi-tenant, billing, admin | Single business logic |
| Scalability needs | Very high | Moderate |
The honest recommendation
If you're not sure which you need, start with a web app. Launch the smallest possible version that solves the problem. Learn from real users. Then, if it works, rebuild as SaaS.
Building SaaS first is the most expensive way to discover you didn't need SaaS.
