The problem
The floor runs on memory. KOTs disappear between the pass and the kitchen. Stock is counted when someone has a free Sunday. Reservations live in a diary that cannot see walk-ins. WhatsApp orders hit a personal phone. GST invoices are a closing-time scramble — and the owner only finds out a dish is 86'd when a table has already ordered it.
In practice
A guest books on WhatsApp, is sat against a live table map, orders from a QR or a waiter with a handheld. The kitchen sees the ticket instantly. Inventory ticks down. The bill is GST-ready. A no-show from last Friday is already on a reminder cadence — not a name the host vaguely remembers.
