What a contractor quote should include

A quote is more than a number — it's a document that protects you if there's a dispute later, and it's often the deciding factor in whether a customer picks you over another contractor. A quote that's vague on scope or pricing invites scope-creep arguments once the job starts. A quote that's specific and professional signals you know what you're doing before you've swung a hammer.

At minimum, every contractor quote should include:

How to price a contracting job

Getting the pricing model right matters as much as getting the number right. Most contractors default to one of two approaches, and picking the wrong one for the job type is a common reason quotes come in too high, too low, or too vague to compare against competitors.

Pricing modelBest forTrade-off
Fixed priceJobs with a clear, well-defined scope — installs, replacements, standard repairsYou carry the risk if the job runs long, but customers strongly prefer knowing the total upfront
Hourly / time and materialsDiagnostics, repairs where the scope is unknown until you're on site, emergency call-outsFairer to you when scope is unpredictable, but harder for the customer to budget against
HybridLarger jobs — fixed price for the defined portion, hourly for anything found once work startsBest of both, but needs a clear line in the quote explaining what triggers the hourly portion

Whichever model you use, materials typically carry a markup on top of your cost price. Most contractors mark up materials 10-20% to cover the time spent sourcing, purchasing, transporting, and handling them — a fair charge, since a supply run is real labor even if it's not billed as an hourly line. Apply your markup consistently across jobs so your pricing stays predictable for you and defensible if a customer questions it.

💡
Quote vs. estimate: a quote is a fixed price for a defined scope of work. An estimate is a ballpark figure that may change once work begins. Quotes are the stronger tool for winning work — they remove pricing uncertainty and reduce disputes later. TradieNotes quotes are valid for 30 days by default.

How to present a professional quote to win the job

Customers comparing multiple contractors are often comparing the quotes themselves as much as the price. A clean, itemised, professionally formatted PDF signals competence before you've done a single hour of work — a handwritten estimate on the back of a business card does the opposite, even if your price is competitive.

Payment options to include on a contractor quote

How you structure payment protects your cash flow and reduces the risk of doing work you never get paid for. Most contractors use one of the following, depending on job size:

Payment structureTypical use
Deposit (10-30%) + balance on completionStandard for small to mid-size jobs. Protects you if the customer backs out after materials are ordered.
Milestone paymentsLarger, multi-stage jobs (e.g. a third at start, a third at rough-in, a third at completion). Keeps cash flowing through longer projects and limits how much unpaid work you're exposed to at any point.
Payment on completionSmall, fast jobs where materials cost is low and the work is done in a single visit.

State your payment terms directly on the quote — don't leave them for a conversation after the customer has already accepted. This avoids the awkward situation of negotiating payment structure after the price is already agreed.

A deposit isn't just about cash flow. A customer willing to pay a deposit is a customer who's serious about the job proceeding — it filters out tire-kickers before you've committed materials or calendar time.

Converting a quote to an invoice

Once a customer accepts your quote, you shouldn't have to rebuild the paperwork from scratch to invoice the job. On TradieNotes, converting an accepted quote to an invoice is free and instant — every line item, the scope of work, materials, labor, and pricing carries straight over from the quote. You just confirm the final details and send.

Contractor quotes, answered.

What's the difference between a quote and an estimate?
A quote is a fixed price for a clearly defined scope of work — the customer knows exactly what they'll pay. An estimate is a ballpark figure that can change once the job is underway. Quotes are stronger for winning work because they remove pricing uncertainty for the customer.
Should I charge hourly or a fixed price for a contracting job?
Fixed price works best for jobs with a clear, predictable scope — it's what most customers prefer because they know the total cost upfront. Hourly billing makes more sense for repair work, diagnostics, or jobs where the scope can't be pinned down until you're on site.
How much should I mark up materials on a quote?
Most contractors mark up materials 10-20% to cover the time spent sourcing, purchasing, and handling them. Some trades mark up higher on smaller jobs to account for the fixed cost of a supply run. Whatever you use, apply it consistently so your pricing stays predictable.
Should I ask for a deposit before starting a job?
For most jobs beyond a quick repair, yes. A deposit of 10-30% protects you against a customer backing out after materials are ordered, and it signals the customer is serious about proceeding. Larger jobs often add milestone payments through the project as well.
How long should a contractor quote stay valid?
30 days is standard. Material and labor costs move, so an open-ended quote exposes you to price risk. State the expiry date clearly on the quote itself so there's no ambiguity if a customer comes back months later expecting the original price.
Can I convert an accepted quote into an invoice?
Yes. Once a customer accepts your TradieNotes quote, you can convert it straight to an invoice from your dashboard at no extra charge. All the job details, line items, and pricing carry over automatically — nothing to re-enter.
