What custom software development actually costs
Anyone quoting a single figure before understanding your integrations is guessing. These are the bands we see in practice, followed by the variables that decide where inside them a project lands.
Outcomes
- A defensible budget range before you commit
- The specific variables that apply to you
- A phased plan so spend follows proof
- An indicative estimate in minutes
Pricing
Where it is used
Small operational system
One process, a handful of roles, one integration — typically €45,000 to €90,000.
Departmental platform
Several processes, external users and two or three integrations — €90,000 to €250,000.
Operational core
Business-wide, multi-country or heavily regulated — €250,000 upwards, phased.
What we deliver
- Integrations: each external system adds scope, testing and failure handling
- User roles: permissions multiply surface area faster than screen count suggests
- Compliance: GDPR, auditability and data residency change architecture
- Data migration: years of messy history is the most underestimated line
- Platforms: adding native iOS and Android typically adds 40 to 70 percent
- Speed: compressing a timeline costs more than the same work done in sequence
Realistic timeline
Discovery
2–4 weeks, and the only phase we recommend paying for before committing to the rest.
Core build
8–16 weeks for most operational systems of moderate scope.
Integration and migration
3–6 weeks, highly dependent on the other systems involved.
Stabilisation
2–4 weeks of parallel running and fixes from real use.
Build or buy
Buy something existing when
- Your process is standard for your sector
- A product covers 85%+ without custom modules
- Budget is below the point where a genuine build is viable
Build custom when
- Licence plus workaround cost exceeds a build over three years
- Your process is the reason customers choose you
- Integration and reporting are the actual bottleneck
Compare three-year totals, not the first invoice: licences, per-seat growth, implementation, integrations and the staff time consumed by workarounds.
What moves the price
Scope breadth
The number of distinct user roles and end-to-end journeys, more than any technology choice, decides the size of the build.
Integration count and quality
Each connected system adds build and test effort; a legacy system with no sandbox can double its own line item.
Data migration
Volume matters less than consistency. Messy history needs profiling, mapping and reconciliation.
Compliance requirements
Audit trails, access control, residency and documentation are engineering work, not paperwork.
Design ambition
A system-based interface is efficient; bespoke visual design and motion are separate, optional cost.
Post-launch expectations
Support response targets and change capacity should be priced up front rather than discovered later.
Where projects go wrong
A price before a scope
Any firm quoting precisely before mapping the process is guessing, and the gap appears later as change requests.
Cheapest day rate
Rate is not cost. A slower team at a lower rate routinely costs more per delivered feature.
Ignoring run cost
Hosting, licences, support and change capacity typically add 15–25% of build cost per year.
FAQ
Questions buyers ask
What is the minimum realistic budget?+
Around €45,000. Below that you are usually better served by configuring an existing product, and we will tell you so.
Why do quotes vary by 3x?+
Usually because suppliers are pricing different scopes. A documented specification is what makes quotes comparable.
Can we phase the investment?+
Yes. We scope a first release that delivers value alone, then phase the rest against results.
What are the ongoing costs?+
Hosting, support and iteration — typically 12 to 20 percent of build cost per year.
