Building desktop software begins by selecting an appropriate platform approach: native across Windows/macOS/Linux, cross-platform frameworks, and the deployment method. A clearly defined MVP and early prototype help verify workflows, performance requirements, and the overall user experience on actual devices.

As the product evolves, reliability, updates, and packaging take center stage. Proper management of file systems, permissions, offline capabilities, and integrations (device APIs, peripherals, enterprise authentication) ensures dependable daily use, while an update system and crash reporting streamline ongoing support.
