An electronic POS system streamlines retail operations by automating the transaction process and tracking important sales data. A basic system includes an electronic cash register and software to coordinate data collected from daily purchases. Retailers can increase functionality by installing a network of data-capture devices, including card readers and barcode scanners.
Depending on the software features, retailers can track pricing accuracy, inventory changes, gross revenue and sales patterns. Using integrated technology to track data helps retailers catch discrepancies in pricing or cash flow that could lead to profit loss or interrupt sales. POS systems that monitor inventory and buying trends can help retailers avoid customer service issues, such as out-of-stock sales, and tailor purchasing and marketing to consumer behavior.
