Summarize this article:

List every item that you have in stock. This will be the list that help you stay organized with your inventory in the future. Keep in mind that you may have multiple locations. If you have more than one stock room, make sure to list which stock room you're taking inventory for. List items that are no longer available. Even if you have run out of a certain item, keep it on the report and you'll list it as "0" stock. When listing your items, think of a good way that will help you search for items on your inventory report. Try listing them alphabetically or by serial number. Under your inventory items, leave a space for description. This will help you keep track of differences in items. For example, you can list separate colors or sizes in this space but have a total inventory count next to the original item. Also, you can mark down if an item is damaged or missing in your description. Depending on the kind of inventory you have, list prices. The price may be what you paid for the item, what price you sell the item at, your bottom expenses, or your bottom earnings from the item. Next to the list of your items, make a column where you can list the amount of stock you have per item. If necessary, leave room for labelsboxes, dozen, pairs, etc.
List your inventory items. List them in an organized fashion. Keep a space for description. Assign a price to each item. Make a column to list stock remains.
