Building desktop software begins by selecting an appropriate platform strategy: native for Windows, macOS, and Linux; cross-platform frameworks; and the deployment approach. A clearly defined MVP and an early 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. Proper management of file systems, permissions, offline functionality, and integrations (device APIs, peripherals, enterprise authentication) ensures daily reliability, while an update system and crash reporting ease ongoing maintenance.
