What is referred to as merchandise or items you own?

The term that best describes merchandise or items you own is "goods." This term specifically refers to tangible products that are made for sale, which can include anything from clothing to electronics. Goods are a fundamental part of commerce and are distinct in that they can be physically touched and handled.

While "assets" and "property" also relate to ownership, they encompass a broader range of items. Assets include not only tangible products but also intangible items like stocks and bonds, as well as cash. Property can refer to a more extensive concept, including real estate and ownership rights.

"Services," on the other hand, refer to activities provided by one party to another, which are intangible and do not involve the transfer of ownership of goods. Thus, in the context of merchandise or items you own, "goods" is the most accurate and focused term.
