in a business process, a quotation, which is sometimes called quoted or estimate, is the way sellers say or write to tell their customers exactly how much money a particular product or service will cost. when a seller quotes his customer 20,000 baht for a product, the seller tells his customers that the price of the product is 20,000 baht. A quotation always starts when a customer or buyer asks for a quotation from a seller, and then a seller will give a quotation to the customer. It is true that a buyer may get quotations from different sellers before the buyer decides which seller to buy from. quotations can be requested and given in whatever way that is convenient to both sekkers and buyers, such as by fax, phone, e-mail and letter.
