Building desktop software begins by selecting an appropriate platform approach: native for Windows/macOS/Linux, cross-platform tools, and the distribution method. A clearly defined MVP and an initial prototype help confirm workflows, performance requirements, and the user experience on real devices.

As the product evolves, reliability, updates, and packaging take center stage. Thoughtful management of file systems, access rights, offline capability, and integrations (device APIs, peripherals, enterprise authentication) ensures daily reliability, while an update system and crash reporting ease ongoing maintenance.
