Building a desktop application begins with selecting an appropriate platform approach: native for Windows/macOS/Linux, cross-platform frameworks, and the distribution method. A clearly defined MVP and an early prototype help verify workflows, performance requirements, and the overall user experience on physical devices.

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