What is the difference between a contractor estimate and a quote?

A contractor estimate is an educated approximation: the price can move as the work reveals itself. A quote is a fixed price for a defined scope: once accepted, the contractor is committed to the number.

A contractor quote, properly written, lists the scope, materials, exclusions, price, and an expiry date, and it becomes binding when the client accepts it. An estimate carries no such commitment, which is why estimates are free-flowing and quotes are careful.

The dispute pattern is predictable: client hears estimate, remembers quote. The fix is one sentence on the document declaring which it is, and, for estimates, the variance to expect. For contractors, quoting fixed prices on well-defined jobs and estimating only the genuinely unknowable is what keeps pricing arguments rare.

A combined estimate and service agreement makes the commitment level explicit before work starts.
