Free Food Delivery App with Promo Codes – Google Apps Script

The whole food business in one build: a public ordering website customers use, a kitchen display the chef works from, a rider screen for delivery, and an admin dashboard over all of it — no commission taken by a delivery platform.

What the customer sees

A public site with the menu browsed POS-style into a cart. Guests can check out without an account or register to keep their history. Items carry extras and add-ons, combo deals are built with a savings calculator that shows what the bundle saves, and promo codes apply as a percentage or a fixed amount. Menu items can be scheduled by day and time, so breakfast disappears at eleven without anyone remembering to hide it.

What the kitchen and the rider see

Orders land on a Kanban board and a kitchen display built for the chef's screen. As an order progresses — pending, preparing, ready, out for delivery, delivered — everyone's view follows it, with real-time notifications. Riders are assigned to orders and the delivery is tracked to completion. Four roles: admin, chef, rider and customer, each with their own dashboard.

Money and stock

Thermal receipts print with a barcode. Revenue analytics run across six charts, daily summary reports identify peak hours, and order reports filter and export to CSV, PDF or print. Stock is tracked with low-stock alerts, so a sold-out item is caught before it is ordered.

Underneath

Google Sheets is the database, images live in Drive, the currency symbol is configurable, and every action is written to an audit log.
