QR Menu
A QR menu is a digital restaurant menu accessed by scanning a QR code placed on the table or counter. Customers see the menu on their own phone, eliminating the need for physical printed menus.
DefinitionPWA (Progressive Web App)
A PWA is a website that behaves like a native mobile app — installable on the home screen, works offline, sends push notifications. PWAs run in the browser but feel like real apps.
DefinitionPOS (Point of Sale)
POS stands for Point of Sale — the system a restaurant uses to take orders, generate bills, manage tables, and accept payments. Traditional POS runs on a terminal at the counter; modern POS runs in a browser on your phone.
Payments
UPI (Unified Payments Interface)
UPI is India's instant bank-to-bank payment system. A customer scans a QR or taps a UPI ID, enters their PIN, and money moves from their bank to yours in under 30 seconds with zero commission.
DefinitionVPA (Virtual Payment Address)
A VPA is your unique UPI identifier — like an email address for money. It looks like 'yourname@oksbi' or 'restaurant@paytm'. Customers send UPI payments to your VPA from any UPI app.
DefinitionRazorpay
Razorpay is one of India's largest payment gateways. It lets businesses accept cards, UPI, NetBanking, wallets, and international payments. ZaikaQR uses Razorpay for subscription billing.
Operations
KOT (Kitchen Order Ticket)
KOT stands for Kitchen Order Ticket — the printed slip that goes to the kitchen instructing the cooks what to prepare. Modern restaurant software prints KOTs on a thermal printer the moment a customer places an order.
DefinitionFloor Map
A floor map is a visual representation of the restaurant's tables and their current state — vacant, occupied, billing pending, or cleaned. Floor maps let owners and staff see the whole restaurant at a glance.
DefinitionDine-in QR Ordering
Dine-in QR ordering means customers seated in the restaurant order from their phones by scanning a QR code at the table, instead of waiting for a waiter to take their order.
DefinitionThermal Printer
A thermal printer is a small receipt printer that uses heat-sensitive paper (no ink). It prints KOTs and bills at the kitchen and counter. The standard size in India is 80mm.
DefinitionTable Turn
Table turn is how many distinct customer groups dine at a table in a single shift. Higher table turn = more revenue from the same number of tables. Dine-in QR ordering typically improves table turn by 20-30%.
DefinitionWait Time
Wait time is how long a customer waits between placing an order and receiving food. Lower wait time = happier customers and faster table turn. Modern QR menus broadcast estimated wait time on the customer's order screen.
Business
Aggregator Commission
Aggregator commission is the percentage cut that food delivery platforms (Zomato, Swiggy) or QR menu platforms take from every customer order. Typically 15-25% on delivery and 10-20% on dine-in QR.
DefinitionGST on Restaurants
GST (Goods and Services Tax) for restaurants in India is currently 5% (no input credit) for standalone restaurants, or 18% (with input credit) for those inside hotels with room rates above ₹7,500.
DefinitionAverage Order Value (AOV)
AOV is the average total of a single customer order. It's a key metric — small AOV improvements compound massively over a year. QR menus often lift AOV by 10-15% via better photos and upsells.
