Estimate vs Quote vs Bid: What's the Difference?

Contractors use "estimate," "quote," and "bid" interchangeably, but they mean different things. Here's what each one actually means.

What is an estimate?

An estimate is your best guess at what a job will cost. It's not a fixed price and can change as you learn more about the scope.

When to use: Early in the process, before a thorough assessment. Renovation work or jobs with unknown conditions.

Legal weight: Low. You're not bound to the number.

A quote is a fixed price for a defined scope of work. Once accepted, that's the price.

When to use: When you've assessed the job and can define exact scope. Straightforward jobs.

Legal weight: High. Typically binding once accepted.

A bid is a competitive proposal for a specific project, common in commercial and government work.

When to use: Tendering for commercial contracts or government projects.

Legal weight: High. Formal offers.

Always include: clear scope, validity period, exclusions, and change order process.
