Building a desktop app begins by selecting an appropriate platform approach: native for Windows/macOS/Linux, cross-platform options, and the distribution method. An clearly outlined MVP and an early prototype aid in confirming workflows, performance requirements, and the overall user experience on real hardware.

As the product evolves, reliability, updates, and packaging become essential. Thoughtful management of file systems, access controls, offline capability, and integrations (device APIs, peripherals, enterprise authentication) keeps the application dependable in everyday use, while an update system and crash reporting ease ongoing maintenance.
