A quote is provided by a business to a customer in response to an enquiry about purchasing goods. The quote estimates the cost of supplying the goods. There is no legal contract when a quote is issued, as the customer can reject the quote or request changes. The business can also change prices or revoke the quote. A quote details the goods, estimated costs including taxes, delivery details, and how long the quote is valid for. A transaction only occurs if the customer agrees to the quote and the goods are delivered.
