The Problem

Small shops in Pakistan struggle with paper-based inventory and billing. Stock goes missing without tracking. Invoices are handwritten and hard to audit. Owners can't see profit/loss without manual calculations. No ledger for customers with pending payments.

The Solution

A simple, fast POS system designed for Pakistani SMEs. Products with barcode/SKU, stock movements with audit trail, one-click invoicing with PDF download, customer/supplier ledgers, and a profit dashboard. Works on tablets and desktops. Supports Urdu/English.
