Traditional POS machines are costly, need training, and tie you to a counter. For a small shop, a POS app on your phone does everything a machine does — and more — for a fraction of the cost. Here's what makes a great POS app for a small shop, and how Dukai compares.
What a small-shop POS app should do
- ⚡ Fast billing — scan a barcode or tap an item, and the bill is ready.
- 🧾 GST invoices — proper bills with CGST/SGST, shared on WhatsApp.
- 📦 Live stock — stock drops automatically with every sale.
- 💳 UPI & cash — print a UPI QR on the bill so customers pay instantly.
- 📒 Udhaar — handle credit customers without a separate book.
- 🖨️ Thermal printer support — print a receipt, or skip paper and send on WhatsApp.
Why a phone POS beats a POS machine
A POS machine can cost tens of thousands of rupees and locks you to one counter. The Dukai POS app runs on the phone you already own, scans barcodes with the camera, and works anywhere in your shop — even at the customer's home for delivery. It also keeps your stock, online store and reports in sync, which a basic billing machine never does.
More than billing
Unlike a standalone machine, Dukai is a full shop system: a free online store for your products, udhaar/khata tracking, low-stock alerts, GST reports, and even running it all from WhatsApp. One app replaces the machine, the khata book and the website.
Frequently asked questions
Is there a free POS app for small shops?
Yes. Dukai is free to start and turns your phone into a full POS — barcode billing, GST invoices, stock and udhaar.
Do I need to buy a POS machine?
No. Your phone is the POS. You can optionally connect a thermal printer or barcode scanner, but neither is required.
Can it print receipts?
Yes. Dukai works with small thermal printers, or you can skip paper and send the bill to the customer on WhatsApp.
Does the POS track my stock?
Yes. Every sale updates your stock automatically, and you get low-stock alerts so you know what to re-order.
