How to sync your inventory offline
The Local-First Architecture
Zeneva's POS environment is built on a "Local-First" architecture. This means your data doesn't just "live in the cloud"—it lives directly on your device's hardware, specialized for high-turnover retail environments in Nigeria where internet stability can be unpredictable.
How Offline Sync Works
Every sale, stock update, or customer addition is instantly committed to a local, encrypted database (IndexedDB) within your browser or app terminal.
Zeneva tracks "Deltas"—only the changes made—rather than re-uploading the entire inventory state, saving data and time.
A service worker continuously monitors your connection throughput. Once a stable >15kbps link is detected, the "Sync Handshake" begins.
If two cashiers update the same stock item while offline, our Vector Clock algorithm resolves the conflict based on causality and timestamps.
Do not clear your browser cache or perform a "Factory Reset" on your POS terminal until the sync icon in the top right corner turns green.
