One piece, from the supplier’s bill to the customer’s bag.

Goods come in from the supplier with a bill. Someone in the office opens a new supplier bill in Nool and types in what is on the paper: item, size, colour, brand, quantity, cost, MRP.

Arrow keys move you down the bill like a spreadsheet. The same kurti in six sizes goes in as one line. Any discount the supplier gave — on a line or on the whole bill — goes in too, and shows up in your accounts as money saved.

Saving the bill does not just add a number to your stock. It creates one entry per piece — five shirts in size 40 become five shirts, each with its own tag number, each remembering which bill it came on and what it cost.

The selling price is rounded the way you price that category, so ₹247.30 becomes the ₹250 that will actually be on the tag.

The tags print in the same order as the supplier's bill, so you can check them against the paper before anything goes on the shelf. Two sizes of tag: 50×35 mm or 35×22 mm.

Each tag has your shop's name, the item, size and model, the price the customer will pay, the tag number, and a barcode. It can also carry your buying price, in a code only you know.

Your stock is now a list of pieces, not a count. Filter it by category, brand, colour or size. See what it is worth, and see what has not moved in months.

There is nothing to count and correct, because there was never a guess. A piece is on the shelf, or it has been sold.

The counter reads the barcode and knows exactly which piece this is. The price comes off that piece's own tag — not from a price list that may have changed since it was tagged.

The GST inside the tag price is worked out for you, line by line. The customer can pay with cash, UPI and card on the same bill, and each is recorded on its own.

A piece can only be sold once. If a second counter scans the same tag, that bill is refused.

The moment the bill is saved, the accounts are updated with it: stock down, sale recorded, GST collected, money into cash or bank.

There is no separate accounts job to do later and nothing to forget. By the time the customer has their bag, your books already know.

At the end of the shift the counter is closed against a counted drawer. If the cash is short or over, the difference is written down rather than quietly absorbed.

The next morning it is still there to look at, along with the day's sales by counter and by salesman.
