A product catalog is a comprehensive list of products or services offered by a company. It typically includes detailed descriptions, specifications, and images of each item available for purchase, as well as information about pricing, availability, and ordering options. The purpose of a product catalog is to provide potential customers with all the necessary details to make an informed decision about which products or services meet their needs and preferences. It can be distributed in print form, online, or through other means depending on the company's marketing strategy and customer base.
