Building desktop software begins by selecting an appropriate platform approach: native for Windows/macOS/Linux, cross-platform options, and the way it's distributed. A clearly defined MVP and an early prototype help confirm 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 capabilities, and integrations (device APIs, peripherals, enterprise authentication) keeps the app dependable in daily use, while an update system and crash reporting ease ongoing maintenance.
