Billing software that works even when the internet doesn't.
Bill customers, manage stock, track regular customers' credit ("udhaar"), and see real profit — all from one simple Windows app that runs entirely on your own shop PC. No internet dependency, no cloud account, no monthly subscription to keep the lights on.
Windows desktop is the primary, fully verified platform. No credit card, no signup required to try it.
Still running your shop on a paper register or a shaky spreadsheet?
Most local shops lose money quietly — through miscounted stock, forgotten credit, and hours spent on manual GST math instead of serving customers.
The old way
- Paper ledgers get lost, torn, or impossible to search when you need last month's sales.
- No idea what's actually left on the shelf until you count it by hand.
- Forgetting who owes how much "udhaar" — or trusting memory instead of records.
- Manual GST calculations that eat into billing time and invite mistakes.
- Expensive cloud POS apps that need internet just to bill, and store your data on someone else's server.
The Billing POS way
- Every bill, saved and searchable forever — reprint or duplicate any past sale in a click.
- Live stock levels with automatic low-stock and out-of-stock alerts.
- Built-in credit tracking — know exactly who owes what, and settle it as they pay.
- GST, discounts and totals calculated automatically on every line, every time.
- Runs 100% locally — bill customers even when the internet is down, with zero recurring cloud fees.
One app, every counter task
Built module by module around how a real shop actually runs its day — from the morning stock check to the evening profit report.
Fast Billing Counter
Barcode-scan or search-to-cart, per-line price override and discount, GST per item, and Cash / UPI / Card / Mixed / Credit payments — with F3/F4/Ctrl+S shortcuts so a cashier can fly through checkout.
Product Catalogue
Categories, barcodes, SKUs, purchase & selling price, GST %, stock levels and photos — plus bulk import/export via Excel to onboard a large catalogue in minutes.
Inventory Tracking
Stock-in, stock-out and adjustment movements with a full audit log, plus automatic low-stock and out-of-stock alerts so a bestseller never quietly runs out.
Customers & Credit (Udhaar)
A directory of regular customers with full purchase history. Sell on credit against a customer and settle their outstanding balance later — partially or in full.
Expense Tracking
Log rent, electricity, supplies and other running costs by category, so your reports show real take-home profit — not just raw sales revenue.
Reports & Analytics
Daily / weekly / monthly / yearly sales and profit, top and lowest sellers, breakdown by category and payment method — exportable to PDF or Excel, or straight to the printer.
Flexible Receipt Printing
USB/Windows thermal printers, network/Wi-Fi printers, or any system printer — with auto-cut and cash-drawer support. A sale is never lost even if the printer is off; reprint anytime from Sales History.
One-Click Backup & Restore
A single portable ZIP backs up your entire database and every product photo. Turn on automatic daily backup straight to WhatsApp for extra peace of mind.
Built for Every Screen
The same app adapts from a full desktop counter setup down to a narrow tablet or phone-width window — the layout rearranges itself automatically.
Up and running before your first customer of the day
No IT team required — a shop owner can set this up alone in one sitting.
Set up your shop
Add your shop name, address, GST number and receipt header/footer, then connect your printer once in Settings.
Add your products
Type products in one by one, or import your entire existing catalogue from an Excel file in a single click.
Start billing
Scan or search a product, adjust price/discount if needed, choose a payment method, then Complete & Print (F4).
Track & grow
Check today's sales on the Dashboard, act on low-stock alerts, and pull a profit report whenever you need one.

Designed to be read at a glance from behind the counter
Every screen is built around the one question a shop owner asks all day: "how is today going?"

- Pick Cash / UPI / Card / Mixed / Credit, then Complete & Print (F4).
