Some cloud managed pos systems are pooly designed with no ability to use a Local Area Network (LAN) to share ticket transactions and rely on the internet to update orders to all devices. For this reason, when the interent is down tickets on those systems are not accessable on all of the devices, causing major stress to your staff and guests as your operation's speed of service is negatively impacted.
Checking out staff at the end of the shift becomes a management nightmare.
Heartland Restaurant was well designed to use the LAN for full system redundancy. When the internet is down, the POS system continues to work using the LAN.
