The amount for which a business is sold is known as the "consideration" or "purchase consideration". This is the total amount paid by the buyer to the seller for the purchase of the business. It includes not only the price paid for the business, but also any other costs or liabilities assumed by the buyer as part of the purchase. The consideration is typically negotiated between the buyer and the seller, and may be paid in various forms, such as cash, stock, or other assets. The consideration paid may also include a portion for goodwill or other intangible assets.
