Reliability Offline & backup server

Keeps running when the internet doesn't.

Most POS systems live in the cloud. GrillTab runs on a small server inside your bar, so a dropped connection on a Friday night is a non-event.

Offline mode

Nothing stops but the internet.

Registers, handhelds, kitchen screens and the cash drawer all talk to the server in your building over your own network.

  • Orders, tickets and cash keep working with no internet at all.
  • Cards keep working offline, within limits you set, and go through when you're back.
  • Online orders wait safely and come in when the connection returns.
  • Backed up every night to the cloud, encrypted.

Backup server

If the server dies, the night doesn't.

Add a second computer as a backup. It keeps a copy of everything, updated every 15 seconds, and takes over by itself if the main one stops.

  • Takes over in about 2 minutes , by itself, or with a manager's tap.
  • No open tab is lost : the copy is never more than seconds old.
  • Registers move to it by themselves.
  • Works with the internet down too.

Questions

What owners ask.

What needs the internet?

Online and delivery orders arriving, new card holds, and features that live in the cloud (the owner website, text messages). Everything in the building keeps working.

How long can it run offline?

Days. Cards taken offline are limited to the amounts you set, to keep the risk small.

Do I need the backup server?

No, it's optional. It's for bars that can't afford a dead computer on a busy night.
