Retailers and marketers will often refer to the area around the checkout instead as the point of purchase (POP) when they are discussing it from the retailer’s perspective. This is particularly the case when planning and designing the area as well as when considering a marketing strategy and offers.
Some point of sale vendors refer to their POS system as “retail management system” which is actually a more appropriate term given that this software is no longer just about processing sales but comes with many other capabilities such as inventory management, membership system, supplier record, bookkeeping, issuing of purchase orders, quotations and stock transfers, hide barcode label creation, sale reporting and in some cases remote outlets networking or linkage, to name some major ones.
Nevertheless, it is the term POS system rather than retail management system that is in vogue among both end-users and vendors.
The basic, fundamental definition of a POS System, is a system in which allows the processing and recording of transactions between a company and their consumers, at the time in which goods and/or services are purchased.
