A point of sale (POS) is the combination of software and hardware where a customer completes a purchase. It records the sale, calculates tax, accepts payment, issues a receipt and updates inventory and sales reports, replacing the traditional cash register with a connected business system.
A modern POS typically consists of a screen or tablet running the selling software, a barcode scanner, a receipt printer, a cash drawer and a payment terminal. The software holds the product catalogue, prices, staff logins and customer records, and sends each completed transaction to a database. Many systems now run in the cloud, so head office can see sales as they happen.
Retailers use POS data for far more than ringing up sales. Stock levels adjust automatically, promotions and discounts are applied consistently, and reports show best sellers, busy trading hours and performance by staff member or store. Hospitality venues add table management, split bills, modifiers and links to the kitchen, which makes a hospitality POS quite different from a retail one.
When choosing a POS, consider how well it integrates with payments, accounting and ecommerce, whether it keeps trading when the internet drops, how easily products can be imported, and how it handles GST. Poor data entry at setup and untrained staff are common causes of unreliable reports, so training matters as much as features.
POS is the central source of truth for sales and stock, so errors here ripple through finance, ordering and marketing. RetailCare supplies and supports POS platforms in Australia, including ERPLY, Nomni, Restroworks and VenueSumo, with local setup and training.
