Restaurant POS Software India — KOT, GST Billing and Kitchen Display

What Indian Restaurant Owners Need in POS Software

A restaurant POS in India must solve a specific set of problems that generic billing software does not address. The challenge starts at the table: a waiter takes an order verbally or on paper, carries it to the kitchen, waits while the chef reads it, and hopes nothing gets lost. Multiply this across 20 tables during a busy dinner service and the chaos becomes apparent — wrong items, delayed orders, forgotten modifications, and frustrated customers.

Modern restaurant POS software digitises this entire flow: waiter takes order on a tablet, it instantly appears on the kitchen display or prints as a KOT in the kitchen, chef prepares in correct sequence, waiter gets notification when order is ready, customer receives bill with correct GST in seconds. No paper, no miscommunication, no billing errors.

KOT System — How It Works

The Kitchen Order Ticket (KOT) system is the nerve centre of restaurant operations. In the Digitruinx Restaurant IT Portal, a KOT is generated automatically when a waiter finalises a table order on their device. The KOT appears simultaneously on:

• Kitchen Display System (KDS): A screen mounted in the kitchen showing live orders in sequence, with preparation time countdown and order priority marking
• Thermal KOT printer: Traditional paper KOT in the kitchen for restaurants preferring physical tickets
• Billing terminal: Real-time order total visible to cashier as items are added

Modifications and cancellations update instantly across all screens — eliminating the "runner carries a revised slip to the kitchen" problem. When an item is ready, the kitchen marks it on the KDS; the waiter's device shows item-by-item ready status for their table.

GST Billing for Indian Restaurants

Restaurant GST in India has specific rules that cause constant confusion and errors:

• AC restaurant: 5% GST with no Input Tax Credit (ITC) — the most common scenario for standalone restaurants
• Non-AC restaurant: Also 5% GST since the AC/non-AC distinction was removed in 2019
• Composite supply restaurants: Restaurants in hotels with declared tariff above ₹7,500 per night charge 18% GST
• Takeaway/delivery: Same GST rate as dine-in, but the billing must correctly indicate the supply type
• Packaged food items sold separately: Different GST rates (5%, 12%, or 18%) depending on the product category

The Digitruinx Restaurant POS is pre-configured with correct GST rates based on restaurant category — eliminating the most common billing compliance error Indian restaurants make. The system generates a proper tax invoice with CGST/SGST split for dine-in, and handles both regular GST invoices and simplified B2C invoices (without customer GSTIN) for most restaurant transactions.

Table Management

The table management module shows a live floor plan with colour-coded table status: available (green), occupied (red), order placed (yellow), bill requested (blue). Waiters can merge tables for large groups, split bills by person or item, and transfer orders between tables when guests move. For restaurants with multiple sections (indoor, outdoor, terrace), each section has its own floor plan view. Reservation management allows pre-booking tables with customer details and special requirements noted.

Swiggy and Zomato Integration

Online food delivery orders from Swiggy and Zomato are a significant revenue channel for most Indian restaurants — and a significant operational headache if managed on separate devices. The Digitruinx Restaurant IT Portal integrates with Swiggy and Zomato through their restaurant partner APIs, pulling delivery orders directly into the POS system. Delivery orders appear on the kitchen display alongside dine-in orders, eliminating the need for staff to manually read and re-enter orders from separate Swiggy/Zomato tablets.

Importantly, the integration handles the billing correctly: Swiggy and Zomato have different GST treatment as marketplace aggregators, and the restaurant's billing must reflect the correct GST position for marketplace-aggregated delivery versus direct sales.

WhatsApp Order Confirmations and Feedback

For restaurants taking phone orders or WhatsApp orders (common for Indian restaurants, especially QSR and cloud kitchens), the system sends an automated WhatsApp order confirmation with estimated delivery time. On delivery, an automatic WhatsApp receipt with the itemised bill is sent. Post-delivery, a feedback request is sent 30 minutes later — collecting Google review links and driving reputation management.

Inventory and Recipe Costing

For serious restaurant operators, inventory management and recipe costing are as important as billing. The IT Portal tracks raw material consumption against each menu item's recipe, flags when ingredients are running low, and calculates food cost percentage automatically. Daily inventory variance reports compare theoretical usage (based on items sold) against actual usage (based on stock takes), highlighting wastage, pilferage, or over-portioning.
