Custom software in Croatia ranges from €1,500 for simple automations to €60,000+ for full platforms and SaaS products. A typical web app or internal tool of moderate complexity sits in the €15,000 to €40,000 range. The final figure depends on scope, integrations, design depth, security needs, and how much is pinned down in writing before development starts.
Quick cost reference
| Project type | Range (€) | Duration |
|---|---|---|
| Simple automations, integrations | 1,500 - 5,000 | 1 - 3 weeks |
| Mid-complexity web apps and dashboards | 5,000 - 25,000 | 4 - 10 weeks |
| Mobile apps and complex web apps | 15,000 - 60,000 | 8 - 16 weeks |
| Enterprise platforms and SaaS products | 60,000+ | 16+ weeks |
Figures cover design, development, testing, and launch. They exclude long-term maintenance.
What drives the price
Eight factors push the number up or down:
- Domain complexity. More rules, exceptions, and edge cases mean more design and testing time.
- Integrations. Every API (accounting, CRM, payments, shipping) adds coding and edge-case testing.
- Design and UX. A functional app ships in 2-3 weeks; a polished version with brand and animations takes 5-8.
- Mobile platform. Cross-platform (React Native, Flutter) runs 40-60% cheaper than two native builds.
- Security and GDPR. Personal data, health, or payments require threat modelling, encryption, and consent flows.
- Scaling readiness. Apps for 100,000+ users daily need different architecture, caching, and load testing.
- Team seniority. Senior developers in Croatia bill €60-€90/hour. Junior teams cost half but often need twice the hours.
- Scope clarity. Written briefs ship faster and cheaper than projects where scope “emerges”.
Fixed price vs hourly, and hidden costs
Fixed price works when scope is defined; it shifts risk to the studio. A real fixed price requires a Discovery phase. Hourly billing suits early product validation or ongoing retainers. Senior rates in Croatia: €60-€90/hour.
Hidden costs to plan for:
- Hosting: €10-€300/month for typical apps, €500-€5,000 for high-traffic systems
- Third-party APIs (SMS, email, payments, analytics): €200-€2,000/month combined
- Maintenance: 15-25% of build cost per year
- Bigger feature changes: €2,000-€20,000
Budget formula: 70% build, 15% buffer, 15% first-year maintenance. A €30,000 build needs a €42,000-€45,000 first-year budget.
Croatian context: EU funds
Through NPOO and Digitalisation Vouchers, Croatian SMEs can receive 40-85% co-financing for digitalisation projects (€10,000-€100,000+). See our EU funds for SMEs article for current calls. R&D tax incentives may also apply.
Frequently Asked Questions
Can you quote based on an email alone? We can give a rough range. A specific proposal requires a conversation and, for larger projects, a Discovery week, which removes about 70% of estimate uncertainty.
What if scope changes mid-project? On fixed price, minor changes within scope are absorbed. Larger features are quoted separately and agreed before work begins.
Is everything paid upfront? No. The standard split is 30% on signing, 40% at midpoint, 30% on delivery. Larger projects use more phases.
