Sync Priorities
Sync Order
When connection restores, the system syncs critical items (payments, orders) first, then inventory, then employee events, and finally analytics. Do not interrupt the sync process -- let it complete fully.
| Priority | Items | Sync Order |
|---|---|---|
| Critical | Payments, orders | First |
| High | Inventory changes | Second |
| Normal | Employee events | Third |
| Low | Analytics, logs | Last |
When Connection Returns
Automatic Sync
When internet restores:
- System detects connection
- Notification: "Connection restored"
- Sync begins automatically
- Critical items (payments) first
- Progress shown in status bar
- "Sync complete" notification
Sync Duration
Sync time depends on queue size:
| Queue Size | Approximate Time |
|---|---|
| Under 50 items | Under 30 seconds |
| 50-200 items | 1-2 minutes |
| 200-500 items | 2-5 minutes |
| 500+ items | 5-10 minutes |
Manual Sync
Force sync immediately:
- Go to Settings > System > Sync
- Tap Sync Now
- Monitor progress
Handling Conflicts
What Are Conflicts?
Conflicts occur when:
- Same item edited offline at multiple locations
- Price changed in cloud while offline
- Inventory count differs
Conflict Resolution
Most conflicts resolve automatically:
| Conflict Type | Resolution |
|---|---|
| Payments | Always syncs (no conflict) |
| Orders | Most recent wins |
| Inventory | Cloud + local changes merged |
| Price changes | Cloud price takes priority |
| Employee edits | Manager notified |
Manual Resolution
Some conflicts need manager review:
- Notification: "Sync conflict requires review"
- Go to Settings > Sync > Conflicts
- Review conflicting values
- Choose correct version
- Confirm resolution
Cellular Backup
Automatic Failover
If configured with cellular backup:
- Internet outage detected
- System switches to 4G/5G backup
- Operation continues online
- Switches back when primary restores
Failover Indicators
- "Primary: Offline"
- "Backup: Connected (Cellular)"
- Slight latency increase possible
Cellular Data Usage
Typical data usage:
| Activity | Data per Hour |
|---|---|
| Normal operations | 50-100 MB |
| Busy period | 100-200 MB |
| Full sync | 200-500 MB |
Best Practices
Before an Outage
