"What does a web app cost?" is the most common question we hear from prospective clients. The honest answer: it depends. But we can give you a very concrete framework.
The short answer
Web App Development Pricing Overview 2026
- Simple tool / MVP: €5,000 – €15,000
- Mid-complexity web app: €15,000 – €50,000
- Complex platform / SaaS: €50,000 – €150,000+
These numbers apply to professional development in Germany using a modern tech stack.
The 8 most important cost factors
1. Feature scope
The biggest cost driver. A simple dashboard with 5 pages costs a fraction of a platform with user management, payment integration, real-time data, and an admin panel.
2. Design effort
Template-based design: €500–€2,000. Custom UX/UI design: €3,000–€10,000. Thoughtful design isn't optional — it determines usage and conversion.
3. Integrations
Every connection to third-party services (Stripe, Mailchimp, CRM, ERP, APIs) costs development time. Budget around €500–€3,000 per integration.
4. Authentication & roles
A simple login is cheap. But multiple roles (admin, manager, user), permissions, 2FA, and SSO get complex. Budget: €1,500–€5,000.
5. Data volume & performance
Apps that process large amounts of data (dashboards, analytics, marketplaces) need optimized databases, caching, and sometimes search engines. That costs extra.
6. Mobile optimization
Responsive web app vs. additional native app. A PWA (Progressive Web App) is often the golden middle ground: web quality with an app feel, without double the development effort.
7. Hosting & infrastructure
Monthly costs of €20–€500 depending on traffic, data volume, and requirements. Vercel, AWS, or your own server — we advise on what's optimal.
8. Support & maintenance
Software needs care: security updates, bug fixes, small improvements. Expect 10–20% of development cost per year.
Realistic price examples
Example 1: Internal Dashboard (€12,000)
A mid-sized company needs a dashboard that consolidates data from 3 sources. Login for 15 employees, 4 views, export function.
- Concept & design: €2,500
- Backend + API: €4,500
- Frontend: €3,500
- Testing + launch: €1,500
Example 2: Customer Portal with Booking (€35,000)
A service provider wants customers to book online, upload documents, and track status — with payments via Stripe.
- UX/UI design: €6,000
- User management + roles: €5,000
- Booking system: €8,000
- Payment integration: €3,000
- Backend + API: €7,000
- Frontend: €4,000
- Testing + launch: €2,000
Example 3: SaaS platform (€80,000+)
A startup wants a multi-tenant SaaS platform with subscriptions, team management, an analytics dashboard, and API access for customers.
Hidden costs that are often forgotten
- Domain & SSL: €20–€100/year
- Transactional email: €0–€50/month
- Monitoring & error tracking: €0–€100/month
- Backup system: €10–€50/month
- GDPR compliance: cookie banner, privacy page, possibly legal advice
How to save on costs
- Start with an MVP: build only the core features. Expand iteratively based on real user feedback.
- Use existing services: Auth0 for login, Stripe for payments, Resend for email — instead of building everything yourself.
- Clear brief: the better you know what you want, the fewer iterations you need.
- Agile approach: two-week sprints with regular feedback avoid expensive wrong turns.
Freelancer vs. agency vs. in-house
Hourly rates compared (Germany, 2026)
- Junior freelancer: €50–€80/hour
- Senior freelancer: €90–€150/hour
- Specialized agency (like S&A Solutions): €80–€130/hour
- Large agency: €120–€200/hour
- In-house developer: €4,000–€7,000/month (+ employer costs)
Our tip: a specialized agency offers the best value. You get a well-oiled team with processes, without the overhead of a large agency.
Conclusion
The cost of a web app depends on feature scope, design, and integrations. For most business applications, expect €15,000–€50,000. Start with an MVP, gather feedback, expand iteratively — that's smart investing.
