Quote vs estimate: what Aussie tradies need to know

Tradies use the words quote and estimate like they mean the same thing. They don't, and the difference matters the day a client waves your piece of paper at you and says you're charging more than you said. Knowing which one you gave, and which one you meant to give, protects your margin and your reputation.

The short version

A quote is a fixed price. You are committing to do the described work for that amount, and once the client accepts it you are generally held to it. An estimate is your best guess at the likely cost. It is not a promise, and the final invoice can come in higher or lower depending on what the job actually takes.

Why the difference bites

If you hand over a document headed Quote and the job blows out, the client can reasonably expect to pay the quoted figure, and you wear the difference. If you call it an Estimate and keep the client updated as costs move, you have room to charge what the work really cost. Under Australian Consumer Law you also can't give a figure and then pile on unexpected charges without a good reason, so vague paperwork cuts against you either way.

• Use a QUOTE for defined work: a deck to a fixed design, a set number of doors hung, a room lined
• Use an ESTIMATE for uncertain work: a reno where you can't see behind the walls, storm-damage repairs, anything with rot or termites in play
• Whichever you give, write down exactly what is included and what is not
• Put a validity date on it so an old price can't be held against you months later

Protect your margin either way

The label matters, but the real protection is a clear scope and billing every variation the day it comes up. A quote with a tight inclusions-and-exclusions list is far safer than a bare number, and an estimate is only useful if you actually track the real costs against it as the job runs, so you can show the client where the money went.

That last part is where most tradies come unstuck. If you're quoting or estimating off gut feel and only finding out the real cost at the end, you can't defend your number. TrackYaTradie lets you build a quote off your own price list, mark it clearly, and then track live costs against it as you work, so your final invoice always has the numbers to back it up.
