Offline Billing, Barcode POS & Udhaar KhataSix things, and where each one stops.
Every capability below runs today. Under each one is the limit that comes with it — because the question worth answering before you spend an evening entering stock is not what an app can do, it is what it cannot.
Offline billing
Power cut, dead tower, finished data pack — the bill still saves.
The moment a bill is saved. Recorded is the whole claim: the sale is a write to the phone in the shopkeeper's hand, and whether the tower is up decides only when the copy leaves it. Scan or search
Add stock by barcode, or type against the shared catalog. Voice entry is planned, not shipped.
Phone camera barcode scanning, plus instant barcode label generation (50×25mm) for loose or packaged goods directly from your counter. Digital khata
Balances per customer, and a reminder sent from your own number.
••• Balance shielded
Privacy Shield: Customers standing at your counter cannot peek at ledger totals. One tap toggles between masked and visible balances.
Quote first, bill later
Give a price without recording a sale. When they agree, the bill is made from the same lines — nothing retyped.
Create estimates and quotations for jobs or orders. Convert to an active bill in one tap when approved — zero retyping. Batch and expiry
Track a batch to its date, and hear about it before it turns.
Daily turnover and demand summaries compile automatically as you bill. No evening spreadsheets or manual arithmetic. Staff, with limits

Three states, and every quantity carries a unit
An item on your shelf is in exactly one of these. You will meet the three words on the stock screen within an hour of installing, so here they are with their colours attached.
- Sellingबिक रहा हैOn the shelf and on the bill screen. This is where an item lives, and it is the only state that appears in search.
- Archivedबंद कर दियाYou have stopped stocking it. Off the bill screen, still in every bill you ever made with it — history is never rewritten to tidy a list.
- Not for saleबिक्री के लिए नहींOn the shelf, deliberately not sellable — a display piece, a reserved carton, the last one held for a customer.
Three, and no fourth. Every quantity carries a unit, and every item is in exactly one of these — which is why “out of stock” is a count of zero and not a fourth state to get out of sync with the shelf.
Three ambient modes. Built for your counter's lighting.
Direct sunlight on an outdoor counter, evening rush under tube-lights, or late-night accounts tallying. Switch modes in one tap with zero screen glare.
