POS is an abbreviation for 'point of sale', a POS system that doubles as a stock and sales control system.With POS systems however, they are designed to be user friendly, with a sole purpose of making life easier and business better. They allow staff to focus their attention on the customer, as well as the physical preparation and sale of products, cementing the most important values of retail. A POS, or point of sale, system can help reduce your paperwork, track inventory and market to your customers through one easy-to-use process, making more time for you to manage your business rather than staying busy and configuring details.
