It runs offline-first and syncs when the internet returns, supports multi-branch stock and FBR-ready invoicing, and ties billing, inventory, purchasing and accounting into one system.

Key facts

  • Offline-first billing: sales save on the device and sync when the internet returns
  • Real-time inventory with batches, expiry, serial numbers and reorder alerts
  • Multi-branch and franchise control from one HQ dashboard

  • Integrated purchasing and accounting, with a REST API and e-commerce sync

POS and Inventory Management Software in Pakistan helps businesses manage sales, billing, stock, purchasing, accounting, and reporting through one connected system. A modern POS system does more than generate receipts at the counter. It can update inventory after every sale, track products through SKUs and barcodes, monitor warehouse stock, manage supplier purchases, record customer credit, and provide real-time sales reports. For Pakistani businesses, features such as offline POS functionality, multi-branch inventory management, FBR-compliant invoicing, tax reporting, barcode billing, stock alerts, and accounting integration can make daily operations more efficient. Retail stores, supermarkets, pharmacies, restaurants, fuel stations, wholesalers, and growing multi-branch businesses can use a POS and inventory management system to connect front-counter sales with back-office operations. By combining billing software, inventory control, purchasing, customer accounts, accounting, and business reporting in one platform, businesses can reduce manual data entry, improve stock visibility, and make better decisions using accurate operational data.

What Is a POS and Inventory Management System?

A POS and inventory management system is software that handles billing, stock, purchasing and reporting together. When a cashier scans a barcode, three things happen at once. The bill is printed. The stock count drops. The sale posts to your accounts.

This removes the gap between the shop counter and the back office. You no longer count stock by hand or re-type sales into a ledger.

Main parts of the system:

  • POS terminal: the billing screen, barcode scanner, receipt printer and cash drawer.
  • Inventory module: stock levels, warehouses, batches, expiry dates and reorder points.
  • Purchase module: supplier orders, goods received notes and supplier payments.
  • Accounting module: sales posting, daily closing, receivables and financial statements.
  • Reporting dashboard: sales, profit, stock and staff reports by branch.

Who Needs POS and Inventory Software?

Core Features of Our POS and Inventory System

Fast Counter Billing

The billing screen is built for touch. It supports barcode scanning, weighed products, discounts and returns. Customers can pay by cash, card, mobile wallet, QR code, credit or a split of these. Cashiers hand over shifts with a clear cash report. Each transaction takes under three seconds on standard hardware.

Real-Time Inventory Control

Every sale and purchase updates stock at once. You see current quantity per item and per warehouse. Low-stock alerts and automatic reorder points tell you what to buy before shelves run empty. Batch and expiry tracking suits pharmacies and food sellers. Serial number tracking suits electronics and appliance shops. Stock moves between branches with a full transfer record.

Multi-Branch and Franchise Management

Owners see all branches from one HQ dashboard. You compare sales, stock and staff performance branch by branch. Prices, promotions and stock rules are set once at HQ and pushed to every branch.

Customer Credit and Loyalty

Many Pakistani shops sell on credit. The system keeps a clear customer ledger with dues, payments and reminders. It also supports loyalty points, store credit and purchase history. You can send offers by SMS or WhatsApp from the same screen.

Quotations, Proforma Invoices and Delivery Notes

Send a quotation to a customer and turn it into an invoice with one click. Create proforma invoices and delivery notes from the same screen. Set custom tax and discount rates per product.

Customer Wallet and Due Invoices

Customers can hold a prepaid wallet balance and top it up. Unpaid invoices can carry a QR code or a payment link, so customers can pay dues online. Each customer has a full account with invoices, payments and balance.

Product Variations and Serial Tracking

Sell one product in many sizes and colours without creating separate items. Track serial numbers for electronics and appliances.

Supplier and Purchase Management

Create purchase orders and send them to suppliers. Record goods received, supplier invoices and payments. Every purchase updates stock and your accounts.

Integrated Accounting and Tax Reports

Sales post to your accounts automatically. You get daily closing reports, profit and loss, and exportable financial statements. Invoices follow the tax format of your country.

Role-Based Access and Audit Trail

Each user sees only what their role allows. Every price change, void, refund and stock adjustment is logged with the user name and time. This helps owners catch errors and theft.

FBR, PRA and Tax-Compliant Invoicing

Tier-1 retailers in Pakistan must connect their POS to the FBR invoicing system. The system sends each invoice and credit note to FBR as the sale happens. Provincial authorities such as the Punjab Revenue Authority (PRA) and Sindh Revenue Board (SRB) run their own invoicing rules for services and restaurants.

Our software can be built to match the rules that apply to your business.

For other markets we support UAE VAT invoicing and Saudi ZATCA e-invoicing.

Tax rules change. Always check current requirements on the official FBR website or with your tax advisor before you go live.

Offline-First POS: How It Works Without Internet

Internet drops are common in Pakistan. Our POS saves every sale in a local database on the terminal first. When the connection returns, the system syncs all queued sales to the cloud in order. It then updates stock, accounts and tax reports.

The result is simple. Counters never stop. No sale is lost. No one needs to re-enter bills by hand.

Integrations and API

Your POS should work with the tools you already use. Our POS can connect to:

  • Online store: sync products, prices and stock with your e-commerce website (for example WooCommerce, Shopify or a custom store).
  • Payment gateways and QR payments: card, mobile wallet and bank QR options.
  • SMS and WhatsApp: invoices, due reminders and offers.
  • REST API: connect the POS to your ERP, CRM or mobile app.
  • Data export and backup: export reports to Excel and keep scheduled backups. Because the software is custom, we add integrations that match your business.

Custom POS vs Ready-Made POS: Which Is Right for You?

Ready-made POS software costs less at the start and is quick to launch. Custom POS software fits your exact workflow and grows with you. Neither is always better.

How Much Does POS Software Cost in Pakistan?

POS cost depends on five things:

  1. Number of branches and terminals.
  2. Modules needed: inventory, accounting, loyalty, tax integration.
  3. Industry rules: batch expiry, pump readings, recipes.
  4. Integrations: payment gateways, e-commerce store, SMS and WhatsApp.
  5. Hardware: scanners, printers, tablets, cash drawers.

Ready-made cloud POS plans in Pakistan are usually listed per month, often from a few thousand rupees for one small business. Those plans normally charge extra for setup, training and add-on modules.
