Building a desktop app begins with deciding the ideal platform approach: native for Windows/macOS/Linux, cross-platform options, and the distribution method. A clearly defined MVP and an early prototype help confirm workflows, performance requirements, and the overall user experience on real hardware.

As the product evolves, stability, update processes, and packaging take center stage. Thoughtful management of file systems, permissions, offline capabilities, and integrations (device APIs, peripherals, enterprise authentication) ensures reliable daily use, while an update system and crash reporting ease ongoing maintenance.
