Concrete is sold by the square foot and bought by the cubic yard, and a good concrete estimate shows both. The sample below prices a 480 square foot driveway from tear-out to sealer. Once the forms are pulled, bill it with the free invoice template.

Cheap concrete fails underneath, so spell out the parts nobody sees after the pour: how deep you dig, how much gravel goes down, rebar or mesh, and slab thickness. Put your business name, phone and email at the top, then the client, the address, an estimate number, the date and how many days the price holds.
Measure the area and write it down as length by width and total square feet, because that is the number the client will compare across bids. List the work in site order, from tear-out to the cure, and close with what is not included, such as lawn damaged by the truck.
Paste the text below into a document, fill each bracket and remove lines that do not apply; a small patio may only need base, pour and finish.
Write the specification in plain words the client can check later with a tape measure: "4 inches of 4,000 psi concrete over 4 inches of compacted gravel, #3 rebar at 18 inches." If the slab ever cracks, that line is what protects you both. The skeleton:
The sample replaces a worn asphalt driveway, 20 by 24 feet, with a 4-inch slab of 4,000 psi concrete over a compacted gravel base, reinforced with #3 rebar and finished with a broom texture. The town requires a permit for the apron at the street. The business, client and prices are made up, and the sample applies sales tax to the whole subtotal for simplicity; how concrete work is taxed depends on your state.

The slab is 480 square feet at 4 inches, which comes to just under 6 cubic yards; 7 yards are ordered to cover the base settling and spillage. Concrete is quoted at $165 a yard, which includes a 15% markup on the plant price. Placing and finishing is priced per square foot because the crew size stays the same on any pour this size. The permit is passed through at cost. This quote is valid for 30 days.
Most concrete contractors start from a price per square foot for each step and check it against the yards they will order. Base prep and tear-out vary the most: digging out old asphalt with a skid steer is quick, while breaking up an old slab by hand next to a house is slow, and soft clay soil can need twice the gravel. Check the truck route before you write a number; a pump or a wheelbarrow line costs more labor.
Ready-mix pricing moves with the season and with short loads, so call the plant before you send a big quote. If you are not sure of the soil, say so on the estimate and price the extra gravel per ton as an option. The estimate vs quote guide covers when a price like that is firm and when it can still move.
With Workeey, the concrete estimate sits inside the job, with the client and the site address. Enter your rates once, including hourly, first hour, call-out, travel, evenings and weekends, parts markup and deposit percent, and the AI builds an itemized estimate from them. Materials like rebar or sealer are priced from the web at your markup, and a line you write yourself, such as "saw-cut control joints", is remembered for the next driveway. Free accounts get 23 quick estimates a month.
Share quote turns the estimate into a quote PDF that is good for 30 days. You send it from your phone, and its Email button opens your own mail app. Your deposit percent shows on the quote, though Workeey does not take the deposit for you. There is no signing in the app: the homeowner gives you the go-ahead, you pour, and one tap converts the estimate into an invoice that Workeey emails with a pay link. More on taking card payments and plans and pricing.
Measure square feet, set thickness and base depth, price each step per square foot, then work out cubic yards (square feet × thickness in feet ÷ 27) plus waste.
Most finishers add 5 to 10 percent for uneven base and spillage, then round up to the plant's smallest increment. Running short on a pour costs far more than a leftover half yard.
Say exactly what reinforcement is in the price. Rebar on chairs costs more than mesh or fiber, and a homeowner comparing bids should be able to see which one each contractor is offering.
Only for conditions the quote names, like soft soil or a buried slab found during tear-out. Price them on the estimate and get a yes before the extra work.
