Answer:
True.
Step-by-step explanation:
An inventory is a document where lists of objects in stock that belong to a person, a department, a community, company, organization, among others, can be added. This is a document characterized as accounting and which aims to quantify the quantity of the stock of a given product.
Inventories are made through spreadsheets, where objects are classified and quantified. The first step to start this spreadsheet is to think and organize which objects are relevant to the "owner" of the stock. Based on this, we can say that the first task in establishing an inventory spreadsheet of all administrative supplies in the office is to think about the supplies used in a doctor's office.
