A quote allows a prospective buyer to see what costs would be involved for the work they would like to have done. Many businesses provide services that cannot have an upfront price, as the costs involved can vary. This can be due to the materials that would be used (which can differ depending on the individual needs of the customer), and the manpower that would be necessary. Therefore, it is common practice for these companies to provide the potential customer with a quote (or estimate) of how much it should cost. A quote can help the prospective buyer when deciding which company to use, and which services they are looking for.
