CafeSystem: from the QR on the table to the bill, one real-time system.
Our own product, end to end: a café's four roles in one live flow.
-
Guest — from the table, no install.
Scans the QR, browses the menu, sends the order. Nothing to download.
-
Waiter — the whole floor on one screen.
New orders, open tabs, service calls; split payments, tips, table moves.
-
Kitchen — orders hit the wall instantly.
Orders land on the kitchen display the second they're sent; tickets print themselves.
-
Owner — menu and end-of-day in hand.
Products, prices, tables, QR codes and revenue reports. No tech skills needed.

A Chrome extension that converts prices and times on any page into your own currency and time zone. No tracking; everything happens in your browser.
