Assets and liabilities usually go together, but they are different from each other. When something is considered to be an asset, this means that this thing can be positive to the company. This means that the thing will provide an economic benefit in the foreseeable future.
When something is considered to be a liability, this means that the item is going to be an obligation or a responsibility that the company has to face. Some assets will go with some liabilities depending on the situation. People usually need to analyze the different items that are given to them so that they can decide if the item is going to be an asset or if it is going to be a liability.
