Hidden Costs to Budget For
- Legal: Terms of service, privacy policy, GDPR compliance — €1,000–€5,000 depending on jurisdiction.
- Design: A polished UI system takes 2–4 weeks. Budget €2,000–€6,000 for custom design.
- DevOps: CI/CD, staging environments, monitoring. Often overlooked until the first outage.
- Customer support tooling: Intercom, Crisp, or Help Scout for handling user questions.
- App store fees: If you launch mobile apps later, Apple and Google both take 15–30%.
Why SaaS Costs More Than a Simple Web App
A SaaS is not a website. It is a multi-user system with billing, permissions, data isolation, and ongoing infrastructure. The complexity lives in the edge cases: what happens when a user cancels mid-billing cycle? How do you handle role changes in a team workspace? What if two users edit the same record?
These are the questions that separate a €5,000 brochure site from a €25,000 SaaS. If your quote seems high, ask what is included. If it seems low, ask what is missing.
FAQ
How long does SaaS development take?
MVP: 4–8 weeks. Growth: 8–16 weeks. Enterprise: 4–8 months. The biggest variable is feature scope and how quickly you can provide feedback.
Should I build in-house or hire an agency?
Hire an agency for the MVP. You get a team (design, frontend, backend, QA) without the recruitment overhead. Move in-house once you have product-market fit and steady revenue.
What tech stack is best for SaaS in 2026?
Next.js + React frontend, Firebase or Supabase for backend/auth/database, Stripe for billing, Vercel for hosting. This stack balances speed, cost, and scalability.
Can I start with no-code and migrate later?
Yes, but plan the migration from day one. No-code tools are great for validation. Once you hit their limits, a custom rebuild is often faster than fighting the platform.
