Shop POS Billing (barcode till, UPI and thermal receipts)

About the Shop POS Billing (barcode till, UPI and thermal receipts)

A till for a shop that runs in your browser and keeps everything on your own device. Add your items once — name, price, barcode, tax rate and stock, typed in or imported from a spreadsheet — and ring up a bill by scanning barcodes (a USB or Bluetooth scanner types into the page; a phone or laptop camera reads codes too), typing a code or a few letters of the name, or pressing a quick button. The bill works out discounts, GST (CGST + SGST, or IGST for a customer in another State), VAT or sales tax, and rounds the total if you want.

Take cash (with the change worked out), UPI (a QR code with the amount for the customer to scan), card, a split of them, or put the bill on a customer’s account (udhaar) and record what they pay later. Every bill gets the next number; the Sales tab adds up each day by payment method and tax rate, and the receipt comes out on a 58 or 80 mm thermal roll or an A4, A5 or Letter sheet, through the print dialog or straight to an ESC/POS receipt printer. In the free preview, receipts, summaries and statements show as page images marked “MySmartCoPilot preview · not for use”, with their totals hidden, and the till’s UPI QR code cannot be scanned; a Premium pass gives the clean receipts and the QR code. Receipts never carry a “Powered by” line.

Common uses

• Grocery and general stores, stationers, chemists, hardware and mobile shops billing at the counter with a barcode scanner.
• Market stalls and small kiosks billing from a phone, with the camera reading barcodes and a Bluetooth receipt printer.
• Shops that sell on credit to regular customers and want the balances, reminders and statements in one place.
• Owners who want the day’s sales by cash, UPI and card, the cash expected in the drawer and the tax by rate for their accountant.

What a GST bill shows (India)

Rule 46 of the CGST Rules lists what a tax invoice must carry. The till prints them from your settings and the bill:

• your name, address and GSTIN, and a serial number of up to 16 characters (letters, digits, “-” and “/”), unique for the financial year — the till restarts the numbers each year when you choose a financial-year number;
• the date, and the customer’s name, address and GSTIN when they are registered;
• for a customer without a GSTIN, their name, address and State when the taxable value is ₹50,000 or more (rule 46(e)) — the till warns you;
• the HSN or SAC code, description, quantity and unit of each item, the taxable value after discounts, and the rate and amount of CGST and SGST (UTGST in some Union territories) or IGST;
• the place of supply with the State for a customer in another State, and a signature line.

How many digits of the HSN code a bill needs depends on your turnover: the HSN Code Finder explains the rule and finds the codes.

Bills of supply, composition and small sales

• Items with no GST (exempt goods) go on a bill of supply (rule 49), and a bill with both taxed and exempt items for an unregistered customer becomes an invoice-cum-bill of supply (rule 46A). The till picks the title by itself.
• A composition taxpayer charges no GST and issues bills of supply with the words “composition taxable person, not eligible to collect tax on supplies” at the top (rule 5(1)(f)): tick Composition taxpayer under Settings.
• For a sale of less than ₹200 to an unregistered customer who does not ask for one, a tax invoice may be left out, provided a consolidated tax invoice is issued for all such sales at the close of the day (section 31(3)(b) of the CGST Act and rule 46). The day summary lists the day’s sales by rate.

Barcode scanners and the camera

• A USB or Bluetooth barcode scanner works like a keyboard: it types the code and presses Enter. Keep the cursor in the scan box, or anywhere on the Bill tab outside a text box — fast typing that ends in Enter is taken as a scan.
• Camera: press Camera and hold the barcode in the frame; every code read goes on the bill. The browser’s own barcode reader is used where it has one, otherwise a reader made for this site (it downloads once).
• EAN-13, UPC-A, EAN-8, Code 128 and QR codes are read. A 12-digit UPC is also found as the 13-digit EAN with a leading 0, and the other way round.
• An unknown code offers to create the item with it. Labels for your own items come from the Label Sheet Maker.

Receipt printers

• Print dialog (any printer): the receipt is drawn at the roll’s own size (58 or 80 mm wide, as long as the receipt) or on a sheet. Choose the receipt printer and its paper size in the dialog, with margins off and the scale at 100%.
• Straight to the printer (ESC/POS): in Chrome or Edge, the till sends the receipt to a printer that understands ESC/POS commands — most 58 and 80 mm receipt printers. Bluetooth reaches Bluetooth Low Energy printers only (Web Bluetooth cannot use “classic” Bluetooth); on a computer, a printer on a serial port (a USB-serial printer, or a Bluetooth printer paired with the computer) works too.
• Picture prints every language, your logo and the QR code exactly as on screen; Text uses the printer’s own font, sends far less data and prints only English letters, digits and basic signs. Print a test slip first: it shows whether the width is right.
• Printers differ: if a printer prints nothing or garbage, try the other width, Text mode, or the print dialog.

Your data stays on this device

• Items, customers, bills and accounts are kept in this browser on this device (IndexedDB). Nothing is uploaded, and you don’t need an account.
• Set a passcode under Data & backup to keep the register encrypted (AES-256) and locked when you step away.
• Clearing the browser’s site data deletes the register: download an encrypted backup regularly (the till reminds you), and restore it on another device to move the shop there. Your own data — items, customers, bills, payments — also downloads as CSV for a spreadsheet or your accountant.

Outside India

Choose VAT or GST (one rate per item, usually included in the shelf price — the receipt shows the net amount and the tax) or Sales tax (added at the till, as in the United States, where you type your state and local rate). The currency, number style and paper size start from your country and can be changed under Settings. UPI payments are offered for rupee bills only.

Limitations

• One device: the till does not sync between devices. Two tabs on the same device share it safely; to move to another device, restore a backup there.
• The till cannot see your bank, UPI app or card machine: check that a payment arrived before you complete the sale.
• No e-invoices (IRN) and no GST returns are made here. Returns after a sale need a credit note (Credit Note Generator); a bill can only be cancelled.
• Up to 20,000 items and 20,000 customers; a bill has at most 300 lines.
• Direct printing needs Chrome or Edge and a printer that understands ESC/POS; other printers print through the print dialog.

Privacy

Your items, customers, bills and payments are kept in this browser on this device and never uploaded. The camera picture is read on the device and never stored or sent. Receipts go only to the printer you choose.
