When dealing with vendors, retailers are presented with a unique variety of challenges. Take, for example, the difficulties in maintaining a current and accurate inventory of products. Since inventory levels are constantly changing, staying up-to-date with inventory is a never-ending struggle which can take up a huge amount of a retailer’s time. A system lacking integration between the retail Point of Sale, eCommerce, and ERP means that staff will not have the most accurate and up-to-date information on inventory levels.
