You tell a customer a job will be "about four hundred bucks," and now they're holding you to it — or you're eating the difference when the wall turns out full of surprises. Estimate and quote aren't the same word, and mixing them up costs tradespeople real money. Here's the difference, and how to price so you stay covered.
An estimate is your best guess at what a job will cost. It's a ballpark, given before you know exactly what you're dealing with, and everyone understands it can move. A quote is a fixed price — a promise. Once a client accepts a quote, that's the number, even if the job takes longer or eats more materials than you figured. One is a forecast; the other is a commitment. The whole difference lives in that word.
Why it matters: if you call a fixed price an "estimate," a client may expect it to hold like a quote. If you call a ballpark a "quote," you've locked yourself into a number you can't actually stand behind. Using the right word sets the right expectation, and expectations are where money disputes are born. Say which one you're giving, out loud and in writing, so nobody's surprised when the final bill lands.
Give an estimate when you genuinely can't see the whole job yet. Old plumbing behind a wall, a fault you have to chase, a renovation where the scope will shift — these are estimate territory, because pinning a fixed price on unknowns is how you lose money. An honest estimate protects you: it tells the client roughly what to expect while making clear the final figure depends on what you actually find once you're in there.
The key with an estimate is to say plainly that it's an estimate, and to explain what could push it up or down. "Around $500, but if the pipe's corroded past the joint it'll be more — I'll call you before I do anything extra." Now the client isn't blindsided, and you're not trapped. An estimate given honestly builds trust; an estimate the client mistook for a fixed price destroys it.
Give a quote when you can see the whole job and price it confidently — a straightforward install, a job you've done a hundred times, work where nothing's hidden. A firm quote is attractive to clients because it removes their risk: they know the exact number before they say yes. If you can offer one without exposing yourself, it often wins you the job over a competitor who'd only commit to a vague range.
But quote only what you can actually control. Include a clear scope — what's covered and, just as importantly, what isn't. "Quote covers supply and fit of the specified unit; does not cover repairs to existing pipework if found faulty." That line is what saves you when the job throws a curveball. A quote without a defined scope is a blank check you've written to the customer, and they'll cash it.
Whether it's an estimate or a quote, put it in writing. A number said out loud on a doorstep is a dispute waiting to happen — memories differ, and yours won't be the version that wins. Write down the price, what it covers, what it excludes, and how long it's valid. Material prices move, so "valid for 30 days" stops a customer from holding you to a figure you gave last spring.
Itemize where you can. Breaking out labor and materials shows the client where the money goes and makes your number feel fair instead of plucked from the air. It also makes the eventual invoice easy, because the pricing is already laid out. Label the document clearly as an estimate or a quote at the top — that one word, in writing, is your best protection if the final figure is ever questioned.
Once the client says yes and the work is done, your estimate or quote becomes the basis of the invoice. This is where keeping the wording consistent pays off: if the invoice line items match what you priced, the numbers add up and there's nothing to argue about. If the final figure moved because the job changed, spell out why on the bill — "additional pipework, agreed by phone on the 14th" — so the client sees an explanation, not a surprise.
The smoother the path from priced work to sent invoice, the faster you get paid. Anything that makes you re-type the same line items twice is a chance for numbers to drift and for the bill to sit unsent. Ideally the job you priced and the invoice you send are the same record, so nothing gets lost between agreeing the price and asking for the money. See how to invoice as a contractor.
In Workeey an estimate lives inside the job you're planning, not as a separate document to lose. Enter the job — the client, the work, the details — and you get a suggested estimate to work from, or you can ask the built-in AI to price it for you and talk you through the number. It's a fast way to give a customer a figure without guessing off the top of your head.
Because the estimate sits inside the job, everything's in one place when the work is finished. You invoice from that same job in one tap, and the client, line items, tax rate, and job photos carry straight over — so the price you agreed and the bill you send stay consistent. Start on the free plan; see pricing, then bill fast to get paid quicker.
Generally no — an estimate is understood as a best guess that can change, provided you were honest and didn't lowball to win the job. A quote, once accepted, usually is binding as a fixed price. Always label which one you're giving so there's no confusion later.
Yes, if the job genuinely changes — but tell the client before you run up the extra, not after. "The pipe's worse than I thought, it'll be another $200, okay to proceed?" A surprise on the final bill damages trust; a heads-up call keeps it. Get agreement to any change in writing.
Quote if you can see the whole job and price it confidently — a firm number wins trust and jobs. Estimate if there are real unknowns. Never give a fixed quote on a job you can't fully see, or you'll end up paying for the surprises yourself.
Usually 30 days is fair, because material prices move. State the validity period right on the quote so a customer can't accept a six-month-old price. If they come back after it lapses, you're free to re-price based on current costs.
