When is an order sent to the POS?
Only after an order is accepted is it sent to your POS.
How does Lightspeed Restaurant K-Series handle orders?
If you want the POS to automatically print orders, you need to be logged in with a user on Lightspeed.
The orders arrive without sound on the POS, but as they are printed, you'll see a ticket for every order.
Possible solutions for the missing sound are:
Buying a kitchen buzzer.
Using a different tablet with the Delivery Manager App. By default, a sound plays when an order is received.
Synchronizing an iPad
An iPad requires synchronization with the Lightspeed back office to receive the latest information. You can update an iPad from the device or your back office. You can learn how by reading this article on the Lightspeed K-Series help center.
