A point-of-sale and billing app built for counter speed: scan or search items, apply discounts and tax, split payment modes, print or share a GST invoice, and keep inventory and day-end reports accurate without a separate reconciliation.

Watch on YouTubeProject Overview
A billing counter is judged on seconds per customer. This POS is designed around that constraint — keyboard and barcode-first item entry, held bills for the customer who forgot something, and a checkout that handles cash, card, UPI, or a split across all three without slowing down. Behind the counter it does the unglamorous work properly: stock decrements on every sale, GST computed per item slab, returns that put stock back, and a day-end report that ties billing to the cash drawer. It keeps selling when the internet drops and syncs when it returns.
What the Product Does
Fast counter billing
Barcode scanning, quick item search, quantity and price edits, line-level and bill-level discounts, and parked bills for interrupted checkouts.
Tax and invoicing
Per-item tax slabs with GST computation, sequential invoice numbering, customer GSTIN capture, and thermal print or digital share of the receipt.
Inventory and purchase
Stock decremented on sale and restored on return, purchase entry with supplier and batch, low-stock alerts, and stock-take adjustments.
Multi-mode and split payments
Cash, card, UPI, wallet, or credit — individually or split across a single bill, with change calculation and outstanding balance tracking.
Offline-first operation
Billing continues without connectivity, with a local queue that reconciles against the server as soon as the link returns.
Reports and day-end close
Sales by item, category, cashier, and payment mode, plus a day-end summary that reconciles billed value against the cash drawer.
Who Uses It, and How
Cashier
- Scan, bill, and take payment in any mode within seconds.
- Park and resume bills without losing the cart.
- Process returns and exchanges against the original invoice.
Store owner
- See live sales across counters and outlets.
- Manage catalogue, pricing, tax slabs, and discounts.
- Close the day with a report that reconciles cash and stock.
Why It Matters
Seconds saved per bill compound into shorter queues at peak hours.
Stock and tax stay correct because they are a by-product of billing, not a separate chore.
Offline capability means a connectivity drop never stops trade.
Day-end reconciliation replaces the evening spreadsheet entirely.
