Grocery delivery app development for a retail chain

Grocery delivery with wholesale pricing, couriers, and online payment

Project Flagman

FlutterFirebaseGoogle Maps

The task

The store took orders via messengers and calls: managers weighed items by hand and passed addresses to couriers, while stock lived in 1C separately from orders.

What we did

We built an app with four roles: the customer orders at retail or wholesale prices and pays online, the picker weighs items, the courier follows a route with live location, the administrator manages the catalog. Stock syncs with 1C, receipts are issued automatically.

Results

Orders come in through the app, not messengers — no manager involved in checkout

Weighed goods and wholesale are calculated automatically, no manual recalculation

The customer sees the order status and the courier on the map instead of calling
