What is the difference between an estimate and a quote?

An estimate provides an approximate cost that may change based on actual work performed. A quote is a firm price offer that is binding if accepted. Both serve as pre-work pricing documents.

What is the difference between an estimate and an invoice?

An estimate is sent before work begins to show the expected cost. An invoice is sent after work is completed to request payment. An estimate becomes an invoice once the work is done.

How long is an estimate valid?

This varies by business and industry. Common validity periods are 30, 60, or 90 days. Many businesses include an expiration date on the estimate. You can add this in the notes or terms section.
