If you have ever searched for software development pricing, you have probably seen answers ranging from £5,000 to £500,000. Both are technically correct — and neither helps you plan a budget for your business.
After delivering dozens of projects for small and medium businesses across Europe, we have a clear picture of what custom software actually costs in 2025. This is not a sales pitch. It is an honest breakdown based on real project data.
The Short Answer
For most small and medium businesses, custom software development costs between €5,000 and €50,000. The range is wide because "custom software" means many different things — from a simple website to a full CRM system.
Here is a more useful breakdown by project type:
Cost by Project Type
| Project | Typical Cost Range | Timeline |
|---|---|---|
| Marketing website with CMS | €5,000 – €12,000 | 4–8 weeks |
| Custom CRM system | €10,000 – €30,000 | 8–14 weeks |
| Internal tools / dashboards | €8,000 – €25,000 | 6–10 weeks |
| Learning platform / LMS | €12,000 – €35,000 | 10–16 weeks |
| E-commerce with custom features | €8,000 – €25,000 | 6–12 weeks |
| Mobile app (iOS + Android) | €15,000 – €45,000 | 12–20 weeks |
These are real-world ranges for business-grade software — not hobby projects, not enterprise systems with hundreds of users.
What Actually Drives the Cost?
Understanding these factors helps you control your budget before and during a project.
1. Complexity of Features (Biggest Factor)
A website that displays static information costs far less than a website where your team publishes articles, manages products, handles user registrations, and processes payments. The difference is not in the design — it is in the number of systems working behind the scenes.
2. Integrations with Existing Tools
Connecting your new software to your email system, payment processor, accounting software, or existing database adds development time. Each integration is a separate piece of work that needs to be built, tested, and maintained.
3. User Roles and Permissions
A system where everyone sees the same thing is simpler — and cheaper — to build than one with different views for admins, managers, staff, and customers. Each role adds complexity.
4. Data Migration
If you are moving from an old system or spreadsheets to new software, your data needs to be cleaned, mapped, and transferred. This can range from a simple import to a complex multi-week migration project.
5. Ongoing Maintenance
Software is not a one-time purchase. Servers cost money. Security updates are required. Bugs appear. Annual maintenance typically runs 15-20% of the initial build cost.
Fixed-Price vs Hourly: Why It Matters
How your agency charges dramatically affects your total cost certainty.
Hourly billing means the final price is unknown until the project is done. Scope changes, estimation errors, and disagreements about what "done" means all push the price up. For a business that needs to budget, this is risky.
Fixed-price billing means you agree on one price before work starts. The agency carries the risk of underestimating. You carry the benefit of knowing exactly what you will pay. If scope changes, it is scoped and priced separately — no surprise invoices.
Hidden Costs Nobody Tells You About
Beyond the build cost, these are the ongoing expenses you should budget for:
| Item | Annual Cost |
|---|---|
| Hosting and infrastructure | €500 – €5,000 |
| Domain name | €10 – €20 |
| SSL certificate | €0 – €200 (often free) |
| Third-party services (email, payments) | €500 – €5,000 |
| Maintenance and updates | €1,000 – €10,000 |
How to Keep Costs Under Control
The businesses that get the best value from custom software do these three things:
1. Start small, validate, then expand. Build the minimum version that solves your core problem. Launch it. Learn what you actually need. Then add features based on real usage, not guesses.
2. Write down your requirements before contacting agencies. You do not need a technical specification — just a clear description of what you need the software to do. This helps agencies give you accurate prices instead of padded estimates.
3. Choose an agency with a proven process. An agency that has built similar projects before will be faster, more accurate in scoping, and less likely to make costly mistakes.
When Custom Software Is NOT Worth the Cost
There are honest moments every agency should share. Custom software is probably not worth it if:
- A well-suited off-the-shelf tool costs €50/month and does exactly what you need
- You are still figuring out your business model and need something to change weekly
- Your budget is under €5,000 — at this level, templates and no-code tools serve you better
- You cannot name the specific problem the software should solve
If any of these describe your situation, we would tell you honestly. A good agency earns trust by being honest about when not to hire them.
