Building desktop software begins by selecting an appropriate platform approach: native options for Windows/macOS/Linux, cross-platform frameworks, and how it's distributed. A clear MVP and an initial prototype assist in confirming workflows, performance requirements, and the overall UX on real hardware.

As the product evolves, reliability, updates, and packaging take center stage. Diligent management of file systems, permissions, offline capabilities, and integrations (device APIs, peripherals, enterprise authentication) ensures dependable everyday use, while a robust update system and crash reporting ease ongoing maintenance.
