QR Restaurant Ordering Platform
RestroSethu
RestroSethu is a complete restaurant management SaaS platform built for modern food businesses. Guests scan a table QR code to browse the digital menu and place orders directly from their phone — no app download needed. At the same time, restaurant staff manage orders, tables, kitchen displays, inventory, invoices, customers, coupons and loyalty rewards all from one powerful admin dashboard.

Client & Project Overview
Target Audience
Restaurants, cafes, food courts and QSR chains that want to modernize table ordering, reduce manual errors, manage operations digitally and improve the overall guest experience.

Challenges
Problems We Were Asked to Solve
Key challenges the client was facing before working with Andnetics.
Real-time simultaneous ordering from multiple tables without conflicts or delays.
Guest experience required zero friction — no app install, no login, just scan and order.
Kitchen staff needed a dedicated live display separate from the admin panel.
Inventory had to auto-update as orders were placed to prevent out-of-stock situations.
Needed a full invoicing and GST billing system integrated into the order flow.
Multi-outlet royalty tracking required a flexible data model across restaurant chains.
Our Strategy
How We Planned the Solution
The approach and planning behind the project before execution began.
01
Built a web-based PWA so guests can order from any phone browser without installing an app.
02
Designed a role-based access system so kitchen, floor and admin staff each see only what they need.
03
Used WebSocket technology to push real-time order updates to the kitchen display and admin dashboard.
04
Built a modular SaaS architecture so features like loyalty, coupons and inventory can be toggled per outlet.
05
Designed a table-QR mapping system that binds each scan to the correct table session automatically.
06
Integrated GST-compliant invoice generation directly into the checkout flow.
