A quote letter (sometimes called a quotation letter or price quotation letter) is a formal written document that a supplier, service provider, or seller sends to a potential customer to give details about the cost of goods or services they are interested in buying.

A quote letter can also be described as an official response to a customer’s request for prices, giving them a clear idea of the costs and conditions before they decide to place an order.

It usually includes:
A list of the products or services being offered.
The unit price and total price.
Any taxes, discounts, or additional charges.
Terms of payment.
Delivery details and validity period of the quote.
Contact information of the supplier.
