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 verify workflows, performance requirements, and the overall user experience on real devices.

As the product evolves, reliability, updates, and packaging take center stage. Thoughtful management of file systems, permissions, offline capability, and integrations (device APIs, peripherals, enterprise authentication) ensures dependable day-to-day operation, while an update system and crash reporting smooth the process of long-term support.
