The worst conversation in the trades starts the same way every time: "But you said four hundred."
You didn't, quite. You said probably around four hundred, before you knew about the second story, the dry rot, or the dog. But the customer heard a promise, because you gave them a number without giving it a name — and an unnamed number always gets heard as a quote. The fix costs nothing. It's vocabulary.
Three words, three different promises
An estimate is an educated approximation. It says: based on what I know so far, jobs like yours usually land here. It's allowed to change when the facts change — that's the entire point of the word — and customers accept that, as long as you called it an estimate up front and said what could move it.
A quote is a commitment. It says: for this scope, this price. Once you call a number a quote, changing it costs you trust even when you're right, because you drew the line yourself. Quotes belong at the moment scope is certain — after the photos, after the visit, after the questions.
A bid is a quote wearing a suit. It's the word for formal, competitive processes — commercial work, property managers, government jobs — where several businesses submit against a written scope and the paperwork matters as much as the number. If a homeowner asks for a "bid" on a deck wash, they mean a quote. If a facilities manager asks for one, they mean a document.
Most residential pricing conversations should run in exactly this order: estimate first, quote second, and the word "bid" saved for the jobs that come with a spec sheet.
The rule: name the number before you say it
The discipline is one sentence long: never let a number leave your mouth without its name attached. In practice, three sentences cover nearly every situation, and they're free to steal:
The estimate: "Based on what you've sent me, you're looking at an estimate of $X–$Y. The final price firms up once I see the condition of the surface."
The upgrade: "Now that I've seen it, I can give you a firm quote: $X, and that's the number."
The boundary: "I can't responsibly estimate this one without a look — the price depends on what's under the shingles. The visit's free and the quote after it is firm."
Notice the second half of each sentence. The name of the number matters, but the reason attached to it is what makes customers relax: they don't mind that an estimate can move, they mind not knowing why. And notice that ranges do quiet work here — "$180 to $260" says estimate all by itself, where "$220" sounds like a promise even when you swear it isn't one.

The number you give a customer starts the relationship. The word you wrap around it decides whether the relationship survives the invoice. Estimates that can move, quotes that don't, bids for the jobs with paperwork — get the names right and the prices take care of themselves.
