FAQ
Desktop software costs
Desktop budget
What does desktop software development cost?
A focused desktop tool starts at around EUR 14,000–25,000 excl. VAT. A full business application with database and interfaces runs EUR 30,000–70,000, complete suites with several modules above that. The calculator narrows the range by platform, scope and data layer.
Windows-only or cross-platform – which is cheaper?
A pure Windows application (e.g. with .NET) is the most economical path. Supporting macOS or Linux as well adds roughly 25% – modern cross-platform frameworks keep the overhead far below two separate builds.
What does hardware integration (scanners, scales, machines) cost?
Hardware integration is priced as its own work package from about EUR 8,500 – depending on protocol (serial, USB, TCP/IP) and vendor documentation. Well-documented SDKs integrate much faster than proprietary protocols that require reverse engineering.
Discuss your desktop project
We review requirements, legacy systems and interfaces and recommend the most economical path.
Technology & operations
Local data, network database or cloud sync?
Single-workstation applications with a local database (e.g. SQLite) are cheapest. Multi-user operation via a network database adds around 25%, cloud synchronisation for distributed sites around 55% – in return you get offline capability plus centralised data.
Is desktop software still relevant in 2026?
For compute-heavy tasks, hardware integration, offline operation and workstations without stable internet, desktop software is often the more robust choice. Many of our clients replace old VB6 or Access applications with modern desktop solutions – or combine a desktop client with a web backend.
What do installer, auto-update and code signing cost?
A professional installer with auto-update mechanism runs about EUR 4,500, code signing (SmartScreen trust, company certificate) around EUR 2,500. Both significantly reduce support effort and security warnings during rollout.
Typical pricing models (overview)
| Model | When it fits | Budget & flexibility | Typical risks |
|---|---|---|---|
| Fixed price (fixed scope) | Clearly defined scope, stable requirements, repeatable delivery. | Predictable total cost; little room for change without a change order. | Scope creep leads to change orders or quality trade-offs. |
| Time & Material | Discovery, legacy, evolving requirements, or close collaboration. | Maximum flexibility; budget transparent via hourly or daily rates. | Without prioritisation, effort can grow—backlog and reviews matter. |
| Retainer / maintenance package | Ongoing operations, updates, small features, and support. | Agreed capacity per month; predictable follow-on cost. | Large changes may still need a separate estimate. |
| Hybrid (milestone + T&M) | MVP or phased releases with clear go-lives, then iterate. | Core delivery fixed price; extensions on a time-and-materials basis. | Define contractually what is in scope vs. extra work. |
Calculators on this page provide indicative ranges; we choose the right model with you based on risk, scope, and planning horizon.
