QRestro: Engineering a Multi-Outlet Cloud POS & Kitchen System
How Infinitix Infotech built a real-time restaurant POS billing software, contactless QR table ordering engine, and Kitchen Display System (KDS) handling 15,000+ monthly orders.
The Client & Operational Context
The client operated a fast-growing regional dining brand with 4 multi-cuisine dine-in branches and 2 cloud kitchen facilities in West Bengal. With weekend customer footfalls surging, their existing legacy desktop billing software struggled with server disconnects, slow thermal receipt printing, and complete lack of synchronization between dine-in tables, takeaway counters, and kitchen chefs.
Bottlenecks Threatening Growth & Customer Ratings
-
Kitchen Ticket Confusion: Paper KOTs were frequently lost or delayed during dinner rush hours, causing average customer wait times to exceed 45 minutes.
-
Inventory Wastage: Raw ingredient stock (dairy, meat, fresh produce) was tracked manually on paper, resulting in undetected spoilage and frequent stock-outs.
-
Multi-Branch Blindness: The management team had to wait until end-of-day spreadsheet reconciliations to view daily revenue across locations.
How Infinitix Infotech Engineered QRestro
Infinitix Infotech designed and deployed a comprehensive cloud-native restaurant management ecosystem customized to high-volume Indian restaurant workflows:
Real-time Kitchen Display (KDS)
Replaced paper slips with WebSocket-driven Android kitchen tablets categorized by prep station.
QR Digital Menu & Ordering
Contactless table QR code scanning allowing guests to order directly without waiting for service staff.
Lightning 3-Click Billing
Split billing, GST compliance, discount codes, UPI QR code integration, and auto-print to thermal printers.
Recipe-Level Stock Tracking
Every menu item order automatically deducts precise ingredient portions from live inventory.
Tangible Business Outcomes
Within 60 days of deployment across all branches, the restaurant brand experienced transformational operational improvements:
- Average order preparation time dropped from 28 minutes to 16 minutes.
- Raw ingredient wastage and spoilage costs decreased by 24%.
- Table turnover speed increased by 42%, allowing 60+ additional dinner covers on peak weekends.
- Owners gained real-time mobile app access to cross-branch sales figures and inventory alerts.
"Infinitix Infotech delivered exactly what they promised. QRestro has eliminated the chaotic kitchen communication we struggled with for years. Our weekend service is now completely calm, our customers get food faster, and our billing is 100% accurate."
