Building a desktop app begins by selecting an appropriate platform approach: native across Windows/macOS/Linux, cross-platform frameworks, and the distribution method. A clearly scoped MVP and an early prototype help confirm workflows, performance requirements, and the overall user experience on real devices.

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