Does billing really work with no internet?
Yes, and not in a limited way. Product search, the cart, payment, the receipt and the stock deduction all run from the phone. The bill is queued and uploads itself when the connection returns. The only things that need a connection are adding a new product, running reports and changing settings.
If the network drops while I am taking payment, will the customer be charged twice?
No. Every bill is given an id the moment the cart is opened, before payment. If your phone resends that bill because it never saw our reply, our server recognises the id and returns the original invoice instead of creating a second one. It is the single most important thing we built.
Do I need a barcode scanner or a computer?
Neither. An Android phone is enough. The camera is the scanner. Send the receipt on WhatsApp, or print it through your phone’s print option to any printer your phone can print to.
Do I have to type in all my products?
No. 5,000+ packaged products are ready with their barcode, name and MRP. Tap Build your shop, tick what you sell, and prices start at MRP. A packet you scan later fills itself in. Only loose goods and your own items need a name and a price.
How long does it take to start?
A few minutes. Sign up with your phone number and shop name, tick your products from the ready list, and ring up your first bill. You do not need the whole shop on day one: scan each item the first time you sell it. No installation visit, no training session and no contract.
I already use a notebook or another app. Do I have to start over?
No. From a notebook: start with today’s bills and enter each customer’s udhaar balance as they next come in, nothing back-dated. From another app: send us your product list as a spreadsheet and we import names, pack sizes, prices and opening stock free, on any plan. Your CA can keep using Tally with the free accountant login or the spreadsheet export.
Can my accountant see the books without me paying for another seat?
Yes. The accountant role is free and uncounted on every plan, including Free. Give them a login and they see the reports they need, nothing more.
What happens if my subscription expires?
You drop back to the Free feature set. Billing keeps working, your data is untouched, and nothing is deleted. We will never lock a shopkeeper out of the till over a payment.
Which languages does it support?
English, Hindi and Marathi across the app, the receipt and Sathi AI’s answers, with numbers written the Indian way (₹1,24,500). Switch the language and what is already on screen is re-read in the new one.
Is my shop data safe, and who can see it?
It is encrypted in transit and at rest, your shop is separated from every other shop, and inside your shop your staff see only what their role allows. We do not sell it, advertise against it, or use it to train AI models. See the Privacy Policy.
Can I get my data out?
Yes. Share or save any report as a PDF from Reports. If you are closing your account, email support@dukanup.com first and we will send you a full copy of your bills free of charge.
