Everything your shop counter needs. Nothing you don't.
Engineered for real Indian retail counters: rapid 3-second billing, barcode gun scanning, thermal POS printing, dynamic UPI QR on invoices, and 60-second day-end till closing.
GST-ready invoices & instant checkout
Generate tax-compliant GST invoices (CGST, SGST, IGST, HSN/SAC codes) or clean non-GST composition bills in 3 seconds. Multi-item autocomplete, discounts, and item notes tailored for high-speed counter queues.
Thermal Receipt Printing (2" & 3" POS)
Direct high-speed printing to standard 2-inch (58mm) and 3-inch (80mm) USB, Bluetooth, or WiFi thermal receipt printers, as well as full A4/A5 laser invoices for wholesale B2B customers.
Dynamic UPI QR Code on Every Bill
Auto-generate a dynamic UPI QR code on counter screens and printed receipts containing the exact bill total. Customers scan with GPay, PhonePe, or Paytm with zero manual amount typing and zero soundbox mistakes.
Day-End Sales Summary & Cash Ledger
Eliminate evening ledger headaches. 1-click day-end audit reports breaking down total revenue across Cash in Drawer, UPI settlements, Card swipes, and Credit balance without manual calculator math.
Barcode & Camera Quick Scanning
Plug-and-play support for handheld USB/Bluetooth 1D/2D barcode scanners and instant camera scanning from your mobile device. Scan EAN/UPC barcodes to add items straight to the invoice.
1-Tap WhatsApp Digital Invoices
Send beautiful PDF invoices or itemized receipt text directly to the customer’s WhatsApp with a single tap. Cuts thermal paper costs and ensures customers never lose their purchase warranty slips.
Your shop name & GSTIN on every tax invoice
No third-party logos or platform watermarks on your customer invoices. Your shop trade name, GSTIN, FSSAI number, bank details, and counter contact info are prominently displayed on every A4 and thermal receipt.
Connect your custom domain (myshop.in)
Deploy your counter POS on your very own custom subdomain or branded domain. Staff access the billing portal via billing.yourbrand.com or secure instant cloud URL with automatic SSL encryption.
Modern counter billing vs outdated alternatives.
An honest comparison against expensive ERP software (Tally Prime, SAP), desktop-bound billing programs, paper bill books, and generic accounting apps.
Phone + laptop counter POS + thermal receipt printing + dynamic UPI QR + 100% white-label branding.
Built for back-office accountants, not fast counter queues. Requires local Windows PC and heavy keyboard training.
Lost carbon copies, manual calculator math errors, no dynamic UPI QR, and chaotic 1-hour evening cash balancing.
