What is retail billing software?
Retail billing software makes quick bills at the shop counter, keeps stock right and shows your sales and cash at a glance. SMI Books does this with GST bills, thermal receipts, UPI QR payments and live stock, on a counter PC and your phone at the same time.
Counter billing
A bill in seconds, cash or UPI
Walk-in or regular customer, type the item, enter the quantity — tax, total and round-off are done. Take cash or UPI and the bill is marked paid.
- Keep one “Walk-in / Cash” party for counter sales
- Find items by name or item code as you type
- Cash, UPI or bank transfer on the same screen
- Sale returns and credit notes from the bill
Thermal receipts
Print on 58 mm or 80 mm rolls
A clean counter receipt with GST split, amount in words and a UPI QR the customer scans to pay — or send the bill on WhatsApp instead of paper.
- 58 mm and 80 mm thermal printers
- UPI QR printed on the bill
- Your logo and shop details
- WhatsApp PDF in one tap
Stock & day end
Know what sold and what to reorder
Stock moves with every bill. The dashboard shows sales for the period you pick, cash in hand, bank balance and the items running low.
- Low-stock alerts per item
- Cash in hand and bank balance
- Day book and sale reports
- Item-wise profit
