Desktop software development begins with selecting the right platform approach: native (Windows/macOS/Linux), cross-platform frameworks, and the deployment method. A clearly defined MVP and an early prototype help confirm workflows, performance requirements, and the overall user experience on real devices.

As the product grows, reliability, updates, and packaging become essential. Careful management of file systems, permissions, offline capabilities, and integrations (device APIs, peripherals, enterprise authentication) makes the application dependable in everyday use, while an update system and crash reporting facilitate long-term maintenance.
