The value of a business can be assessed through the value of its assets, which include both tangible and intangible assets. Tangible assets refer to those physical items that can be inventoried and valued, which include office equipment, fixtures, or other physical items of value that is a part of the business.
Intangible refers to those assets including contracts, company brand, intellectual property, partnerships, business models, or strategic ideas. An accountant could help in valuing intangible assets.
Asset valuation gives you a limited scope on the valuation of a business and does not predict the potential earning value that the company can accomplish.
