Every order you take on your LNB iPad app will be automatically synced to your desktop control panel. However if you take orders offline, you may check that your orders have been synced or sync them manually:
1. Go to your Dashboard > Orders
2. Select the order that you want to sync and slide it to the left
3. Tap on Sync
If you have several orders that you want to sync at once, you may click on the button Edit on the right top of the app then click on All orders at the bottom of the page then on Sync.
