What is a POS System?

A POS (Point of Sale) system is the technology that allows your business to process customer transactions. Think of it as the digital cash register—but with many more capabilities.
Modern POS systems include both hardware (like card readers, receipt printers, barcode scanners, and iPads or terminals) and software that tracks sales, inventory, and customers.

How Does It Work?

When a customer is ready to check out, the POS system records the sale, calculates the total including taxes, accepts payment, and updates your inventory automatically.

Types of Businesses That Use POS Systems

Retail stores – Restaurants – Cafes and food trucks – Service-based businesses (like salons or repair shops)
