The Difference Between a Quote, Estimate, and Invoice

Navigating Client Documents

When dealing with clients, you'll likely use several types of financial documents. Understanding the distinction between them is vital for clear communication and legal protection.

What is an Estimate?

An estimate is an educated guess of how much a job will cost. It is not legally binding and is subject to change as the project scope becomes clearer. Use estimates for projects where the final cost is uncertain.

What is a Quote?

A quote (or quotation) is a fixed price offer. Once a client accepts a quote, you are generally legally bound to deliver the work at that price, regardless of whether it takes you longer than expected. Use quotes when you have a precise understanding of the project scope.

What is an Invoice?

An invoice is a formal request for payment for goods or services that have already been delivered (or are scheduled to be delivered according to a contract). It is a legally binding document that creates an account receivable.

Best Practices

Always clearly label your documents. Never send an invoice when a client asked for an estimate, as this can cause confusion and damage the client relationship.
