Live demo · Software · Shops, supermarkets & retail chains

A queue that keeps moving.

Scan, pay, print — in the time it takes to bag the shopping. Stock falls with every bill, offers apply themselves, and the counter keeps going even when the internet doesn’t.

The problem

“The billing queue gets long the moment three customers walk in.”

What is retail POS software?

Retail POS software is the billing system at the counter: it scans barcodes, applies GST and offers, takes UPI or cash and prints the bill in seconds. Ours keeps billing when the internet drops, reduces stock with every sale and closes the day with one report, synced to your accounts.

Built around your workflow: this demo is a starting point — screens, fields, rules and integrations are made to fit your business.

Steps to bill a barcoded item

Before: Look up, type, totalWith the system: 1 scan

Counted on the demo · how we measured

Counted on the demo: one scan adds the item with its price and GST, and the bill total updates by itself.

01 · The problem

What problem does it solve?

A busy supermarket bills on an old desktop program. Items without barcodes are looked up in a printed list, discounts are worked out on a calculator, and UPI payments are checked on the owner’s phone before the customer can leave.

When the internet or the old server goes down, billing moves to a notebook, and stock never quite matches the shelves again. At closing, someone adds up cash, UPI and card by hand.

  • Walk-outs at peak

    Customers leave full baskets when the queue doesn’t move.

  • Slow look-ups

    Loose and unbarcoded items are hunted for in a list.

  • Stock that drifts

    Notebook bills from outages never reach the system.

  • Day-end guesswork

    Cash, UPI and card totals are added up by hand.

02 · The solution

How does Retail POS fix it?

  1. 01

    Scan first, search second

    A barcode scan adds the item; anything else is found by name or code in two keystrokes.

  2. 02

    Payment confirmed at the counter

    The UPI QR shows the exact amount and the counter is told when it lands; for cash, the change is worked out.

  3. 03

    Keeps billing offline

    Bills are saved on the counter when the connection drops and sync on their own when it returns.

  4. 04

    One-tap day close

    Cash, UPI and card totals, returns and stock movements in one report — and posted to Tally.

FAQ

Retail POS FAQ

All questions →
What is retail POS software?

Retail POS software is the billing system at the counter: it scans barcodes, applies GST and offers, takes UPI or cash and prints the bill in seconds. Ours keeps billing when the internet drops, reduces stock with every sale and closes the day with one report, synced to your accounts.

Does the POS work without internet?

Yes. Bills are saved on the counter while the connection is down and sync automatically when it returns, so the queue never stops.

Will it work with our barcode scanner and thermal printer?

Yes. Standard USB and Bluetooth scanners and 58 mm or 80 mm thermal printers work with it; weighing scales can be connected for loose items.

How is GST shown on a retail bill?

Each item carries its HSN code and GST rate. The bill shows the tax included in the prices and the totals by rate, so your returns match your sales.

Can we run several counters or stores?

Yes. Each counter has its own bill series, stock is shared per store, and the owner sees every store’s sales in one place.

Does it post sales to Tally?

Yes. Daily sales, returns and payments can post to Tally automatically, so your accountant doesn’t retype them.

Can customers get the bill on WhatsApp?

Yes — as an add-on the bill can go to the customer’s WhatsApp instead of, or as well as, the printed receipt.
