Billing and accounts app for Indian shops
Bills, stock and udhaar, in one diary.
Make a GST bill while the customer waits, see which medicines expire next month, and send payment reminders on WhatsApp. The app keeps working when the internet drops.
Free to start. Works offline. In English, Hinglish, हिन्दी and اردو.

What it does
Built for the counter. Ready for your accountant.
Grocery, medical store or wholesale: the daily work takes two or three taps.
A GST bill while the customer waits
Pick the party, add items by name or barcode, and save. CGST, SGST or IGST, HSN, discount and round-off are worked out for you.
- Paper
- A4, 58 mm and 80 mm thermal
- Sharing
- PDF or image on WhatsApp

Know what expires before it does
Every batch keeps its own MRP and expiry date. The batch that expires first is sold first, and the app reminds you before stock goes out of date.
Low-stock alerts, rate lists from Excel or CSV, and barcode scanning with the phone camera.

See who owes you, and remind them in one tap
Each customer and supplier has a running ledger. Send a statement, a payment reminder or a UPI payment link on WhatsApp from the same screen.

FAQ
Questions shopkeepers ask us.

Does it work without internet?
Yes. After the first visit, billing, printing and the ledger work offline. Internet is needed to sign in, to send on WhatsApp, for Cloud sync and for updates.
Where is my data? Can anyone else see it?
On your own phone or laptop. If you switch on Cloud sync or Cloud backup, a copy is kept in our database in Mumbai so that devices you have joined to your shop can read it. Take a backup every week as well.
What if I change my phone?
Save a backup file on the old phone, then open the app on the new phone and go to Settings, Backup, Restore. With Cloud sync on, sign in to the cloud on the new phone and the books come back.
Is it suitable for a medical store?
Yes. Batch, expiry, MRP and drug licence number on the bill, with alerts before stock expires. It works for Unani, Ayurvedic and allopathic stock alike.
What about large companies?
The Enterprise plan covers branches, staff logins, cloud sync and data migration. Send an enquiry.
How do I delete my account?
