Best Practices to Create a Professional Estimate

Invoice VS Estimate VS Quote

From the financial and contractual aspects of the business, quote, estimate, and invoice- these three documents hold immense significance. However, the use, purpose, and intent of these documents are different. Have a look:


An invoice is financial evidence of the transaction that occurred between a buyer and seller. It is a formal request of payment by the seller, representing the final amount owed by the buyer.


When compared to a quote, an estimate is a less formal document and does not bind the buyer. It contains the anticipated costs of products & services. The buyer may negotiate on the cost estimated by the seller.


A quote is a commercial document, legally binding the buyer to stay on the fixed terms once agreed upon. It usually contains the itemized listing of the products and services with a fixed price.
