Restaurant POS and KOT billing software: a buyer’s guide

Restaurant POS software is the system that takes an order at the table or counter, sends a KOT (kitchen order ticket) to the right kitchen station, prints a GST-compliant bill, accepts payment and quietly updates stock and sales reports in the background. Choosing the right one decides how fast your service runs during a Friday night rush — and how much you actually know about what sells, what gets wasted and where money leaks.

This buyer's guide explains the features that matter for dine-in, takeaway, cloud kitchens and cafés, how KOT flows work, what to check on GST billing, hardware, pricing ranges in India in 2026 and the questions to ask before you sign up.

What restaurant POS software should handle

Restaurant formats differ, but most need a common set of capabilities. The table shows which features matter most for each type of outlet.

You can try a working restaurant billing flow — table selection, KOT and bill — in the restaurant POS demo, alongside a general retail POS demo for counters and bakeries.

KOT billing software: how orders move from table to kitchen

A KOT is the instruction that tells the kitchen what to cook. Good KOT billing software removes shouting, handwritten slips and forgotten items.

1. Order taken: a captain enters items on a handheld app or the cashier enters them at the POS, with notes such as "less spicy" or "Jain".
2. KOT routed: items are split automatically — tandoor items to the tandoor printer, beverages to the bar, desserts to the pastry counter.
3. Kitchen display (optional): instead of paper, orders appear on a kitchen display screen with timers.
4. Additional orders: new KOTs are added to the same table as guests order more.
5. Modifications and cancellations: recorded with a reason and staff name, which reduces misuse.
6. Bill generated: all KOTs for the table combine into one bill, with split-bill options for groups.
7. Payment and settlement: cash, card, UPI QR or a mix, recorded against the bill.

GST billing and compliance features

A restaurant billing system must produce correct invoices every time. At minimum, check that it handles:

• Your GSTIN, business name and address printed on every bill
• The correct GST rate for your type of establishment, split into CGST and SGST (or IGST where applicable)
• Sequential invoice numbering that cannot be quietly edited or deleted
• Service charge shown separately and only as your policy and applicable consumer guidelines allow
• Your FSSAI licence or registration number on bills where required
• Credit notes for refunds and cancelled bills
• GST reports summarised in a format your accountant can use for returns

GST rates and rules for restaurants depend on factors such as whether the outlet is standalone or within a hotel, and rules on service charges and bill details can change. Confirm the correct setup with your chartered accountant and check current FSSAI and consumer affairs guidance before configuring your POS.

Inventory, recipes and cost control

Billing is where money comes in; inventory is where it quietly leaks. Recipe-based inventory is the feature that separates a basic billing app from a proper restaurant POS.

How recipe mapping works

Each menu item is linked to its ingredients. One plate of paneer butter masala might use a set weight of paneer, butter, cream, tomato gravy and spices. Every time the dish is billed, those quantities are deducted from stock automatically.

What it tells you

• Theoretical vs actual consumption: if the system says 20 kg of chicken should have been used but physical stock shows 25 kg gone, you have a wastage, portioning or pilferage issue.
• Low-stock alerts before you run out of key ingredients mid-service
• Purchase orders to regular vendors based on par levels
• Food cost percentage per dish, which guides pricing decisions
• Central kitchen transfers for chains preparing gravies or bases in one location

Set up recipes gradually, starting with your top-selling and highest-cost dishes. Mapping every garnish on day one usually leads to abandoned inventory modules.

Cloud POS in India: online orders, reports and multi-outlet control

A cloud POS stores data online, so owners can check sales, top items and cancellations from a phone while away from the outlet. For growing restaurants this visibility is often the main reason to switch from older desktop billing software.

• Online order integration: orders from food delivery marketplaces and your own website or app arrive directly in the POS and print KOTs, without retyping on separate tablets.
• Menu sync: mark an item out of stock once and it updates across channels, where integrations support it.
• Central menu and pricing: chains can push menu changes to all outlets while allowing local prices.
• Offline mode: billing and KOT printing must continue during internet outages and sync later. Test this before buying.
• Reports: hourly sales, item-wise performance, payment modes, staff-wise discounts and outlet comparison.

If you are planning your own ordering channel, POS integration is essential. The food delivery app development guide explains how app orders should flow into billing, and the restaurant website design guide covers online ordering and table booking on your site.

Hardware and setup checklist

Software is only half the setup. Plan hardware based on outlet size and service style.

Prices vary by brand and specifications; the ranges above are typical for small and mid-size outlets. A reliable router with a mobile data backup is worth adding for cloud systems.

Restaurant POS pricing and questions to ask

Typical software pricing in most setups:

• Cloud POS subscription: commonly ₹5,000 – ₹25,000 per outlet per year, with add-ons for inventory, online order integration, loyalty or extra devices.
• One-time licence desktop software: often ₹10,000 – ₹40,000 plus annual support charges.
• Custom POS for chains or special workflows: ₹2,00,000 and above, plus maintenance.

Before choosing, ask vendors:

1. Does billing and KOT printing continue offline, and how does sync work?
2. Which online ordering channels and payment devices integrate, and at what extra cost?
3. Can I export all sales, customer and inventory data if I leave?
4. What support is available on weekends and late nights, when restaurants are busiest?
5. Is onsite installation and staff training included?
6. How are price increases and add-on charges handled at renewal?

Try the flow before you buy

Run a mock rush with your own staff on any POS you shortlist: take ten table orders, add items, cancel one, split a bill and settle by UPI. The system that feels fastest to your team is usually the right choice.
