Every bill opened at the counter or ordered by a customer via QR appears on the kitchen screen automatically. The kitchen sees the queue and waiting times clearly, with no paper tickets.
Orders appear with their waiting time. The kitchen accepts and completes them from one screen, and front-of-house sees straight away which dishes are ready to serve.
Shops with a hot kitchen, a cold kitchen and a drinks bar can give each one its own screen, and each station only sees the items it has to make.
