A product in business is a good or service that can be bought or sold. It can be a physical item, like a building or clothing, known as a tangible product, or something less concrete like an insurance policy, known as an intangible product. Each product has a unique identifier or model number assigned by the manufacturer for identification. Products can be grouped into product lines based on their function, client[1] groups, or price ranges. Traceability is also important, particularly for products like food where it’s crucial to track their journey from origin to commerce de détail[2] for health reasons. A product’s sustainability is another key aspect, with initiatives like the EU’s Digital Product Passport proposing material passports to list all materials in a product for recovery and recycling.

A service is also regarded as a type of product.
