QR table ordering for a small café: guests scan and order right at the table (no app install), the counter gets live orders with one-tap done/cancel and thermal-ticket printing, and the owner sees today's orders, revenue and best-seller — all inside one HTML file, works with the internet off, no subscription.

The problem

Vietnamese cafés are charged 99k–500k/month for POS suites built for chains. A small shop just wants guests to order themselves and the kitchen to see it.

The solution

• Guest flow: pick a table → menu by category → size & hot/iced → send order, get an edit code
• Counter flow: new orders glow, print bill, mark done
• Owner: daily order count, revenue, best-seller — no dashboard login needed

Result

The full order → kitchen → close-of-day loop runs for real in a single file. It's the demo we open on a call: order a coffee, watch the counter screen light up.
