The basics

What is an Estimate, and why is it important?

An estimate is a document that communicates to a customer the full description of the costs and scope involved in a product or service before the final invoice is issued. It will serve as an estimated price, giving a mutual understanding on the part of the business and the customer regarding price, terms, and conditions.

It is an informal document usually used during the initial stages of sales between the seller and customer. It is also a way to convey agreement and negotiate on the price and scope of work before it commences. It is also known by the names of proforma invoices or cost estimates, or bids.
