If a client asks months later why the driveway cost more than the slab next door, the breakdown shows the concrete, the pump, the steel and the hours, line by line.
It is on the quote page as Your private breakdown (PDF), and it never appears in the customer's link, PDF or email.
What a good concreting quote needs
- Area and thickness of the slab, path or driveway, and the concrete strength.
- Reinforcement: mesh type and number of sheets, or steel to engineering.
- Excavation and base: depth, crushed rock, compaction.
- Formwork, control joints and the finish: broom, exposed aggregate, coloured.
- Access: a line or boom pump if the truck can't reach.
- Removing old concrete and disposal.
For a step-by-step guide, read how to write a quote customers say yes to.
On every concreting quote
- Licence
- Include on the quote: Contractor licence number (where your state requires one).
- Whether you need a licence depends on your state and what the job is worth. In NSW you need a contractor licence and a written contract for residential building work over $5,000 inc GST. In Queensland a QBCC licence is needed for building work valued over $3,300. Other states set their own rules, so check your regulator before you quote.
- Compliance
- Structural slabs and footings may need engineering. If they do, put it on its own line.
- Deposits on home building work are capped by state law: 10% in NSW; in Victoria 10% under $20,000 and 5% at $20,000 or more; and in WA builders can't ask for more than 6.5% on contracts from $7,500 to $500,000.
- GST
- If you are registered for GST, Karven adds 10% once and shows one total inc GST. If you are not registered, there is no GST line. More in GST on quotes.
- Deposit
- Booking the truck and the pump costs you before the pour. Set your deposit % once (within your state's cap for home building work) and they pay it by card when they accept, or with your bank and PayID details.
- Example: the sample job above is $1,561.56 inc GST, so the 10% deposit is $156.16.
- Variations
- Dig out and find tree roots or soft ground? Add a variation on the accepted quote with the extra excavation and base, and the customer signs it on the link before you box up.

How concreters usually price a job
- Most residential concreting is priced per square metre for a plain finish, with decorative finishes added per square metre.
- Concrete supply is per cubic metre, so thickness matters as much as area.
- Pumping, demolition and excavation are separate lines because they change job to job.
- Concrete prices move. Keep the validity short and say so on the quote.

Common questions
How do I work out cubic metres for a slab?
Length times width times thickness in metres, plus a bit for waste and uneven ground. Karven's slab calculator does it when you enter the size, and works out the mesh sheets too.
Should a concrete pump be on every quote?
Only when the truck can't get close enough to pour. When it's needed, list it as its own line so the customer understands the cost.
How do I quote exposed aggregate or coloured concrete?
Quote the plain slab first, then the decorative finish per square metre. Make it optional and the customer decides.
How long should a concreting quote be valid?
Many concreters keep it to 30 days or less because supply prices change. Put the validity on the quote.
Can I see how I priced a concreting quote months later?
Yes. Open the quote and download Your private breakdown (PDF). It is never sent to the customer.

It is free for 21 days with no card needed. Then Starter is $29/mo inc GST with unlimited quotes. Card deposits cost Stripe's fee plus 0.5% to Karven.
