BUILT FOR
A notebook for udhaar, a calculator for bills, and a guess about what is left on the shelf. Thyantra Billing puts all three in one place.
WHAT IT DOES
Everything a small shop needs, nothing it does not
Five tabs: Sales, Products, History, Customers and Settings. Each one does its job without a manual.
Fast billing
Tap products to add them to the bill, adjust quantities and complete the sale. Receipts carry your shop name and print through any printer your phone can see.
Stock that stays right
Stock goes down automatically with every sale. Prices and stock are re-checked when the sale is confirmed, so nothing is oversold. Low-stock and out-of-stock warnings on every product.
Customer credit ledger
Record a 'Credit Sale (Pay Later)' against a customer. See who owes what at a glance, record payments as they come in, and open the full history for any customer.
Sales reports
Today's and yesterday's sales, 7, 30 and 90-day ranges, monthly trend and top-selling products. Export sales to CSV for your accountant.
Your data stays with you
Everything is stored only on your phone. We never see it. Back up to Google Drive or email whenever you like, and restore on a new phone.
Light and dark, four currencies
Rupee, Dollar, Euro and Pound. Switch between light and dark themes from the header. English interface with Indian number grouping.
HOW IT WORKS
Up and running in four steps
No sign-up and no setup wizard. Install, add products, bill.
Add your products
Name, price and stock. A product image link is optional.
Tap to bill
Cash sale, or 'Credit Sale (Pay Later)' against a customer.
Record payments
When a customer pays back, record it and the balance updates.
Check and export
Today's sales at a glance; export CSV when your accountant asks.
SCREENS
The app, as it is
Real screenshots from the current build. Light and dark themes included.
YOUR DATA
It stays on your phone
There is no account to create and no server behind the app. Your sales and customer list never leave your device unless you share them.
On your phone only
Products, sales and customers live in the app's private storage. Other apps cannot read them, and neither can we.
Backup and restore
One tap creates a backup file you can keep on Google Drive or email to yourself. Restore it on a new phone and carry on.
No account, no ads, no tracking
No sign-in, no analytics, no crash reporting. The app goes online only to show a product image from a web address you typed in.
What it does not do yet
We would rather tell you now than have you find out after installing.
- GST invoices with GSTIN and tax breakdown
- Collecting payments by UPI inside the app
- Sending bills on WhatsApp (you can share the PDF receipt through any app)
- Barcode scanning
- Syncing between two phones (one phone, one backup file)
