Building mobile software for commercial field operations requires treating network connectivity as an enhancement rather than a prerequisite.
Local-First Persistence
Every transaction—whether generating a billing invoice or recording inventory weighment—is committed immediately to a local encrypted SQLite database on the mobile device.
Background Conflict-Free Sync
Once connectivity is detected, a lightweight background sync worker packages local records into signed JSON batches and submits them to custom REST endpoints, ensuring zero data loss and uninterrupted operations in low-signal areas.
