A warehouse is very necessary because if the company has an overloaded storage area, it will be difficult to check existing goods or products. Other things like the activity of mixing up new stock and old stock will only make you confused when you take notes and check stock items. When there are these two items, it’s a good idea to separate the old stock and the new stock, so that you can easily find out how many old stocks are sold and not yet sold. You can also provide a special place for your new stock to avoid getting mixed up.
