Quote vs. Estimate: What’s the Difference?
People use “quote” and “estimate” interchangeably, but they promise different things. Using the wrong word sets the wrong expectation — and expectations are what disputes are made of.
| Aspect | Quote | Estimate |
|---|---|---|
| Firm price vs. educated guess | A quote is a fixed, firm price: “this job costs $2,400.” If you got the numbers wrong, that is generally your problem. An estimate is an approximation: “this will likely run $2,000–$2,800 depending on what we find.” | Use quotes when the scope is fully defined and you can price with confidence. Use estimates when unknowns remain — renovation work, repairs, anything where opening things up reveals surprises. |
| Wording that protects you | On a quote, state the expiry date and exactly what is included — and what is not. On an estimate, state the assumptions behind it and that the final invoice reflects actual work. “Estimate” in the title plus a range beats a single number every time. | Whichever you send, get written acceptance before starting. A verbal “sounds good” is where estimate disputes begin. |

Frequently asked questions
Is an estimate legally binding?
Generally less so than a quote, but a wildly exceeded estimate without warning still causes disputes. Communicate before the final number surprises anyone.
Should estimates show a range?
Yes — a range with stated assumptions is more honest and more protective than a single precise-looking number.
Can I convert an estimate to a quote later?
Yes. Once unknowns are resolved, issue a firm quote superseding the estimate, and get it accepted before proceeding.
