Estimate vs Quote vs Bid: Which One Should You Send
The practical difference between an estimate, a quote and a bid, and the one line that protects you whichever word you use.

A quote is normally a fixed price you are committing to. An estimate is a considered approximation that can move with the scope. A bid is a price submitted into a competitive process.
Customers use all three interchangeably, so the word on the document matters far less than what the document says about changes.
The line that matters more than the word
"Changes to the scope are priced in writing and approved before the work is performed." One sentence, and it converts a vague number into a defensible process.
Without it, every discovery behind a wall becomes a negotiation you are having for free.
Exclusions are where the arguments actually live
Permits, disposal, remediation, furniture moving, after hours access, repair to structure found behind finishes. Name what is not included and the dispute never starts.
An allowance is the honest way to price an unknown
Some things genuinely cannot be priced when you write the number. The customer has not chosen the tile, or nobody knows what is under the floor until it comes up. Guessing high loses the job and guessing low starts an argument later.
An allowance names a figure for that item, says plainly that it is an allowance, and says what happens to the price if the real cost lands above or below it. It is not a hedge on the whole estimate, it is a fenced off line inside an otherwise firm one, and customers accept it easily because it is obviously fair in both directions.
What a bid usually adds that the other two do not
A bid goes into somebody else's process, and that process normally sets the format. There will be a due date and time, often a required form, and frequently a list of alternates to be priced separately so bids can be compared line against line.
Read those instructions before pricing anything. Bids are regularly thrown out for arriving late, for missing a required attachment or for not pricing an alternate, all of which are administrative failures rather than pricing ones, and all of which are avoidable by reading the package first.
Put the number in a document, not a text message
A price in a text thread has no exclusions, no expiry, no change order line and no way to prove what was attached to it. It is also the version that gets quoted back at you months later, without the three sentences of context that surrounded it.
Send a document every time, even for a small repair. It takes a minute, it prices the job in the customer's mind rather than in a chat window, and it is the difference between a professional and somebody with a van.
Expire it
Put a valid until date on everything you send. Material prices move, and an open ended offer is a liability you signed yourself up for.

Questions people ask
Is an estimate legally binding?
Generally an estimate is an offer rather than a contract, and it becomes binding when the customer accepts it and you begin work. What it binds you to is the other question, and that is decided by what the document says. An estimate with a clear scope, named exclusions and a written change order clause binds you to that scope at that price. A bare number binds you to an argument.
How far over an estimate can the final price go?
As a matter of general contract practice, the price can move to the extent the document says it can, which is why the change order line matters so much. Separately, several states regulate how far a final residential bill may exceed a written estimate without fresh written consent, and the rules and the figures differ. Check your own state's home improvement rules before assuming there is no ceiling.
Can I charge for an estimate?
Yes, and it is common where producing the number means real diagnostic work rather than a walk around. Say it up front, say what the fee covers, and say whether it is credited against the job if the customer goes ahead. Charging without saying so first is the only version of this that damages anything.
Should I send a quote or an estimate for a small repair?
For a small job with a visible scope, a quote is usually better, because a fixed number is easier to say yes to and there is little room for the scope to move. Keep the exclusions line anyway. The times a small repair goes wrong are almost always the times something was found behind a wall, which is exactly what that line is for.
How long should I leave a price open before it expires?
Long enough for a normal decision and short enough that your material pricing still holds, which for most residential work means a couple of weeks to a month. The number matters less than having one on the page. An offer with no expiry is one you can be held to after your costs have moved.
What is a bid bond?
A bid bond is a surety instrument that accompanies a bid on some public and larger private work, guaranteeing that if you win you will actually enter into the contract. It protects the owner from a low bidder walking away. It is obtained from a surety rather than written by you, and the bid instructions will say whether one is required and for what amount.
