How to write a quote for a job: win the work and get paid without arguments

Updated 20 August 2026 · By the Badger team

A good quote does three jobs: it wins the work, it fixes the price so there's no argument later, and it starts the paper trail that gets the invoice paid. Most quote disputes — and a lot of unpaid invoices — trace back to a quote that did only the first job. Here's how to write one that does all three.

General information, not legal advice — consumer law and building-industry rules vary by state and trade, so check the rules for yours.

Quote or estimate? Say which, mean it

An estimate is an educated guess that the final bill may differ from. A quote is a fixed price for defined work — and once the customer accepts it, it generally forms the basis of your contract. Label the document clearly as one or the other. Giving a "quote" you privately mean as an estimate is how jobs end in a standoff over the extra $800.

What every quote needs

• Your business details — name, ABN, contact — and the customer's name and the job address.
• The scope, specifically. "Supply and install 6 downlights in kitchen ceiling, existing wiring" wins arguments that "electrical work" loses. The scope is what protects your price.
• What's excluded. The two or three things a reasonable customer might assume are in — rubbish removal, patching and painting, parts above a stated allowance. Exclusions written down cost nothing; exclusions explained after the fact cost the relationship.
• The price, with GST handled properly. Quotes to consumers should lead with the GST-inclusive total. If you're not registered for GST, there's no GST to show.
• Variations. One sentence: work outside this scope will be quoted separately before it's done. That sentence turns "while you're here, could you also…" from a margin-killer into billable work.
• A validity window. "This quote is open for 30 days" — shorter when material prices are moving. An expiry protects you from being held to last quarter's prices and gives the customer an honest nudge.
• Payment terms. Deposit if you take one, progress payments on bigger jobs, and when the balance is due. Terms agreed at the quote are enforceable; terms that first appear on the invoice are much weaker — this is the single most valuable habit on this page.
• How to accept. A signature line, a reply email — or best, a link where the customer taps Accept.

Get acceptance in writing, every time

Verbal acceptance feels fine right up until the invoice is disputed. Written acceptance — even an email saying "go ahead" — pins the scope, the price and the terms to the job. If it ever comes to a letter of demand or a small-claims hearing, the accepted quote is the document the whole case stands on. Online acceptance does this automatically and timestamps it.

Quoting habits that win more work

• Quote fast. The first professional quote in the customer's inbox frames the job; quotes sent a week later answer someone else's framing.
• Itemise enough to show value, not enough to invite line-item haggling. Group the job into a few clear components rather than one bare number or forty rows.
• Offer the optional extras as options. A clearly priced "add the extra power point: $180" upsells without padding the base price.
• Follow up once, politely, a few days before the quote expires. Quotes die of silence more often than of price.

From accepted quote to paid invoice, without retyping

The quote and the invoice are the same information twice — so let software carry it across. With Badger Invoices (free forever), you send the quote, your customer accepts it online with your trading terms agreed along the way, and the invoice drafts itself from the accepted quote: same lines, same price, no transcription errors, full paper trail from "can you take a look at the job?" to paid.
