Restaurant POS System

The Challenge

Restaurants needed restaurant POS software that could take orders, handle payments, route tickets to the kitchen, and assign orders to delivery drivers, while scaling to multiple cashier stations and staying fully functional if the internet dropped, without forcing the business to adapt to an off-the-shelf tool that did not fit how it actually operated.

What We Built

Rather than adapt an off-the-shelf package, we built this as custom POS software from the ground up: a Windows desktop point-of-sale application in Flutter, engineered as an offline-first POS system that scales horizontally, where adding a new cashier station just means installing the software and signing in with an account. Under the hood we used Redis for caching, PostgreSQL as the database, and batched order processing, with full offline support that queues orders locally and syncs them back to the server once connectivity returns. WebSockets tie it together as real-time POS software, keeping the till, kitchen display, and admin panel in sync the instant an order moves through the system.

• Windows desktop POS for order-taking and in-store payment processing
• Support for pickup, delivery, and walk-in order types from one consistent ticket flow
• Cash and card payments with built-in tip and discount presets
• Orders routed directly to a kitchen display/ticket workflow
• Delivery-driver assignment for orders going out for delivery
• Role-based accounts for admin, cashier, and driver, with admins able to sign into both the POS and the web admin panel
• Horizontally scalable: new cashier stations are added by installing and signing in
• Offline-first design that queues orders locally and syncs once back online
• Real-time updates across the till, kitchen display, and admin panel via WebSockets
• Built-in sales, revenue, and top-item reporting across every station
• Redis caching and PostgreSQL for fast, reliable data handling

Where It Stands

Deployed as the core restaurant POS software for Bocconcino Pizza & Donairs in Burlington, Ontario, live since June 2026, where we continue to manage and maintain both the offline-first POS system and its admin panel today.
