What is a POS machine?

POS stands for point of sale. In India the phrase covers two devices: the card terminal that accepts payments, and the billing POS - a touch-screen machine that runs billing, stock, GST and customer records for the whole shop. A small business shopping for a POS machine usually needs the second, which can also take the payments.

What is the difference between a POS machine and a card swipe machine?

A card swipe machine (EDC terminal) only accepts payments. A billing POS runs the sale itself - items, GST invoice, stock, customer - and then takes the payment, either by UPI QR or by pushing the amount to an integrated card terminal so nothing is typed twice.

How much does a POS machine cost for a small business in India?

Phone-based billing apps start free or at a few hundred rupees a month. Full counter machines are a one-time device purchase running into the tens of thousands of rupees plus a software subscription, and card terminals are usually rented from payment providers with a per-transaction charge. Registered businesses claim back the 18% GST as input credit.

Can I use my phone as a POS machine?

For billing, yes - the NukkadShops Quik App runs billing, inventory, offers and loyalty on an ordinary smartphone, and is a sensible way to start. When volume grows, the same catalogue moves to a counter machine without changing systems.

Does a POS machine need internet to work?

It needs internet to sync, not to bill. A good machine bills and prints offline and syncs automatically when the connection returns. Card and UPI payments do need connectivity on the terminal side.

POS machine for small business: the 2026 buyer's guide

In India, "POS machine" means two different devices: the card terminal your bank offers, and the billing computer that runs a shop. Most small businesses need both jobs done. Here is how to buy once and cover both.

POS machine for small business - Android POS at a retail counter

The direct answer first: when a small business in India says "POS machine", it means one of two devices. The first is the card terminal - the machine customers tap cards on, offered by banks and payment companies. The second is the billing POS - the touch-screen computer that runs the shop: billing, stock, GST, customers. They solve different problems, and the most common buying mistake is getting one and assuming it does the other's job.

The two machines called "POS"

	Card terminal (EDC)	Billing POS
What it does	Accepts card and UPI payments	Runs the store: billing, inventory, GST, loyalty - and takes payments too
Where it comes from	Banks and payment providers (Pine Labs, Payswiff, PhonePe, Razorpay)	POS vendors, with the software
How it is priced	Usually rented, plus a small per-transaction charge	Device one-time, software as a subscription
What it cannot do	Bill, track stock or produce GST reports	Accept a card without a terminal or QR connected to it

The trap: buying only the card machine

A card terminal records payments, not sales. Take one from your bank and you can accept cards tomorrow - and still write invoices by hand, count stock from memory and reconstruct GST at month-end. Payments are the last five seconds of a sale; everything before those five seconds is what a billing POS automates. If you buy only one machine, buy the one that does the whole sale.

One purchase can do both jobs

A modern Android billing POS takes payments as well: UPI by QR, and cards through an integrated EDC terminal. The bill amount is pushed to the card machine, so nothing is typed twice, and every payment reconciles against its bill automatically. NukkadShops integrates with terminals from Pine Labs, Payswiff, PhonePe and Razorpay, and one bill can be split across UPI, card and cash on a single receipt. Buy the billing machine, and the payments question dissolves into it.

The seven things to check

Offline billing. The counter keeps billing and printing when the internet drops, and syncs later.
A printer built in. One device on the counter, not a nest of wires and adapters.
Barcode speed. Scan-and-sell with instant item search - test it at rush-hour pace.
GST done by the machine. Line-level tax with HSN codes and filing-ready reports, automatically.
Stock that updates itself. Every bill decrements inventory in real time.
Customer memory. Khata, loyalty and purchase history tied to a phone number at checkout.
Service you can name. Who answers when it fails on a Saturday evening, and how fast.

What a POS machine costs

Mobile billing apps start free or at a few hundred rupees a month - genuinely useful for a business run off a phone. Counter machines are a one-time device cost running into the tens of thousands of rupees, plus a software subscription. Card terminals from payment providers are typically rented, with a small per-transaction charge. All of it carries 18% GST that a registered business claims back as input credit. At the serious end of the market, vendors - including us - quote device and software together after a demo, based on your counters and stores.

Thirty minutes on a real machine answers this faster than thirty tabs. Bill your own products on it.

Match the machine to the business

Run from a phone today. The Quik App puts real POS features - billing, inventory, offers, loyalty - on the smartphone you already own, with a path to a counter later.

First proper counter. The Aspire: 11.6-inch, printer built in - the default first billing machine for kiranas and small stores.

A counter that queues. The Pro2 for speed, or the dual-screen Elite-A when customers should see the bill as it builds.

Billing that leaves the counter. The NS MPOS: handheld, battery-powered, prints where the customer stands.

A food business. Different animal - KOTs, tables, kitchens. Start with DINO, our F&B POS.

The bottom line

Decide which jobs need doing. If it is only card acceptance, your bank will oblige. If it is running the shop - billing, stock, GST, customers - buy a billing POS and let it absorb the payments job through an integrated terminal. Our vendor-by-vendor view of the whole market is in the best POS software in India.
