Retail industry

The POS unit handles the sales to the consumer, but it is only one part of the entire POS system used in a retail business. The controlling servers, or "Back-office" computers, typically handle other functions of the POS system such as inventory control, pricing, purchasing, receiving and transferring of products to and from other locations. Other typical functions of a POS system are: store sales information for enabling customer returns, reporting purposes, sales trends and cost/price/profit analysis. Customer information may be stored for receivables management, marketing purposes and specific buying analysis. Many retail POS systems include an accounting interface that "feeds" sales and product losses, cash drawer expected totals, and cashier productivity information to independent accounting applications.
