Merchandising is any practice which contributes to the sale of products to a retail consumer. At a retail in-store level, merchandising refers to displaying products that are for sale in a creative way that entices customers to purchase more items or products.

In retail commerce, visual display merchandising means merchandise sales using product design, selection, packaging, pricing, and display that stimulates consumers to spend more. This includes disciplines and discounting, physical presentation of products and displays, and the decisions about which products should be presented to which customers at what time. Often in a retail setting, creatively tying in related products or accessories is a great way to entice consumers to purchase more.

Merchandising helps to understand the ordinary dating notation for the terms of payment of an invoice. Codified discounting solves pricing problems including markups and markdowns. It helps to find the net price of an item after single or multiple trade discounts and can calculate a single discount rate that is equivalent to a series of multiple discounts. Further, it helps to calculate the amount of cash discount for which a payment qualifies.
