Built for the rush before the rest of the market opens.
The busiest hour at a dairy shop is often the one before most software gets tested on: a queue of the same regulars, a measure of milk each, and a bill that has to be fast because the next customer is already waiting.

Three things a general billing app misses.
Speed matters more than anywhere else
A repeat sale to a regular should take one tap, not a search. The till opens already loaded with three items rung up, because that is closer to what the first minutes of the morning actually look like.
Milk by the litre, same as grain by the kilo
Loose, measured goods take a quantity and a rate on every screen, so half a litre never gets billed as a whole one, and the arithmetic is shown on the line rather than hidden in a total.
Monthly settling, not daily cash
Many dairy customers pay at month end, not at the counter. The khata ledger tracks a running balance per customer, so settling day is reading a number, not reconstructing a month from memory.

What owners ask us first.
Is it fast enough for a morning rush of regulars?
Search, the cart and payment all run from the phone, with no round trip to a server for a routine sale, and the same product list your regulars buy from every day.
Can it bill milk and other goods by measure?
Yes, any loose or measured item takes a quantity in the unit you sell it in, litres or kilos, priced per unit, on the till, the cart and the receipt.
How does monthly khata settlement work?
Every sale to a customer on khata adds to their running balance; a part payment or a full settlement is logged against it, so the balance shown is always current.
Not quite a dairy shop? That is fine.
DukanUp fits any shop that buys stock in at one rate and sells it at another: a medical store, an electronics dealer, a hardware shop, a stationery counter, whatever yours is called. The till, the khata, the stock and the purchase register work the same way regardless of what is on the shelf.
