Concrete Invoice Example: Yards, Forms, and Finish

Short answer: A concrete invoice example has to show both units — the surface the customer sees and the volume you bought. This one covers 456 sq ft of flatwork at 4 in, which is 456 ÷ 81 = 5.63 yd³, plus 0.6 yd³ for the thickened edge, so 7.0 yd³ was ordered. The ready-mix itself is $1,372 of an $8,588.80 invoice — 16 percent. Forms, steel, placement, stamping, joints, and cure carry the rest.

Below is one finished job: a 16 by 22 stamped patio behind the house, a 4 ft walkway connecting it to the driveway, no truck access to the back yard, poured on a 94°F day in September. The universal checklist for any bill is in what to include on an invoice. What follows is the concrete part — the volume math, the lines that are not concrete at all, and the seven items customers call about.

What does a stamped patio invoice look like line by line?

Every rate is one crew’s number in one market. Haul distance from the plant, fuel surcharges, mix design, and season move these more than anything else, so take the structure and price it from your own costs the way concrete pricing guide sets out.

How do square feet become cubic yards on the bill?

One division, and it belongs on the invoice header where the customer can check it.

Volume in cubic yards is area in square feet times thickness in feet, divided by 27. For a slab of a given thickness that collapses to a single divisor, because 27 × 12 = 324.

Slab thickness	Divide sq ft by	456 sq ft becomes
4 in	81	5.63 yd³
5 in	64.8	7.04 yd³
6 in	54	8.44 yd³
8 in (footings, piers)	40.5	11.26 yd³

Then add what the flat area does not include: thickened edges, haunches, footings, and the fact that a subgrade compacted by hand is never perfectly flat. This job took 5.63 yd³ of slab plus 0.6 yd³ of thickened edge and ordered 7.0, roughly 12 percent over the takeoff. Ordering short costs a cold joint in the middle of a patio, which is permanent. Ordering long costs a wheelbarrow of waste.

Plants also sell in fixed increments and charge a short-load fee under their minimum yardage. Put that fee on its own line if it applies, rather than smearing it across the per-yard rate where it reads as an inflated concrete price.

Why is the concrete itself only 16 percent of the invoice?

Because the truck delivers a liquid, and everything before and after it is what makes it a patio.

Line 7 is $1,372 of an $8,588.80 total. The other 84 percent is excavation and haul-off, 8.2 tons of stone, 122 linear feet of forms set to a 2 percent fall, tied steel, five people moving seven yards by wheelbarrow, two finishes, joints cut the next morning, 48 hours of wet cure, and two coats of sealer with a return trip at 30 days.

Say that on the page when a customer prices ready-mix online and works out the yardage. The number they found is line 7, and it is the smallest major line on the invoice.

What do forms, steel, and finish each buy?

Three separate operations, three separate units, and none of them scale with each other.

Line	Unit	What decides the quantity
Forms	linear foot	Perimeter, plus every radius, step, and isolation joint. Radius forms cost more per foot than straight
Thickened edge or footing	linear foot	Where the slab carries load or meets open ground
Reinforcement	square foot, or by the piece	Mesh versus rebar, grid spacing, and whether it is chaired to mid-slab or left on the ground
Placement	square foot or yd³	Access, crew size, and pour rate
Finish	square foot	Broom, hard trowel, exposed aggregate, or stamped — a spread of several dollars per foot
Joints	linear foot	Spacing rule, not area
Cure and sealer	square foot	Weather and finish type

Joints deserve their own note. Cutting them is silica work, and OSHA’s construction silica standard puts a wet-cut saw, water, and housekeeping controls on the equipment list. That cost belongs inside the per-foot joint rate rather than absorbed into the finish.

Line 10 against line 11 is the clearest example on this invoice: $4.20 per sq ft for stamped, $0.60 for broom, same truck, same day. Stamping adds color hardener, release agent, mats laid and lifted in sequence while the slab is in a narrow window, hand-detailing at every edge, and a sealer schedule that pulls you back in a month.

How much do access and haul distance change the labor?

More than anything else on the sheet, and they are invisible in a photograph of a finished patio.

Line 9 exists because the truck could not reach the back yard. Seven yards through a 36 in gate is roughly forty wheelbarrow loads, five crew, and forty minutes of the truck’s clock. The alternatives are a line pump or a buggy, both of which are their own line with a setup charge and a minimum yardage.

Walk the access before quoting. Note gate width, slope, overhead wires, soft ground the truck cannot cross, and distance from the closest hard stand. Then write what you found on the estimate, so the access line is agreed before the crew arrives and not explained afterward.

Which weather lines belong on a concrete invoice?

The ones you actually did, with the temperature written next to them.

Hot placement pulls water out of the surface faster than bleed water can replace it, which crazes and cracks the top. Line 13 covers evaporation retardant, chilled water on the ticket, and 48 hours of wet burlap under plastic on a 94°F day. Cold placement is the mirror image: accelerating admixture, heated water, blankets, and sometimes a longer wait before you can cut joints.

Both belong on the invoice as named lines with the reason attached. Absorbing them into the per-yard price means the customer who pours in October pays for the customer who poured in July.

How do I build my own yard and foot rates?

Price the pour day, then divide by what that day produces.

Four crew at a fully burdened $40 an hour for eight hours is $1,280. Add $170 for the mixer, saw blades, forms consumed, stakes, and fuel and the day costs $1,450. Divided by 456 sq ft, raw placement and finishing labor is $3.18 per sq ft. Add overhead — last year’s fixed costs spread over the square feet you actually poured, call it $0.45 — and cost is $3.63. That figure is a floor, not a price. Lines 8, 10, and 11 together come to $5.73 per sq ft on this job, because stamping adds a second pass in a narrow window and a return trip for the sealer.

Material is separate, and this is where margin and markup get confused. The plant charged $166.60 per yard. To hold a 15 percent margin you divide by 0.85, which is the $196.00 on line 7. Multiplying by 1.15 instead gives $191.59, and that is only a 13 percent margin. On seven yards the difference is small; across a season of driveways it is a truck payment. The ready-mix delivery ticket in your hand is a receipt, not an invoice, and the difference between the two documents is worth being clear about — invoice vs receipt covers it.

Which lines get argued about, and how should they read?

The line they call about	What they mean	Write it like this
7.0 yd³ against 5.63 computed	”You bought more than you poured."	"5.63 yd³ of slab plus 0.6 yd³ of thickened edge, ordered 12 percent over for grade variation. Tickets 41277 and 41284 attached.”
Wheelbarrow placement, $406	”The truck brings it."	"No chute access. Seven yards moved 84 ft through a 36 in gate by five crew.”
Stamped $4.20 against broom $0.60	”It is the same concrete."	"Color hardener, release, mats set and lifted on a timed window, hand detail at every edge, two coats of sealer with a return at 30 days.”
Hot-weather measures, $265	”Weather is not my problem."	"Placed at 94°F. Evaporation retardant, chilled water on ticket 41284, and 48 hours of wet burlap under plastic.”
Saw-cut joints, $175.50	”You cut cracks into my new patio."	"Joints do not stop shrinkage, they choose where it happens. Cut 1 in deep, a quarter of the slab, on a 9 ft grid.”
Excavation, $957.60	”It is just dirt."	"14 yd³ hauled off, hand-dug at the marked gas line and along the foundation.”
Sealer second coat	”The job is finished."	"Second coat scheduled at 30 days; it is priced in line 14 and already paid for.”

How do I explain the estimate against this invoice?

The estimate was a price for a patio that did not exist; the invoice is the record of the one that does, and the delivery tickets are stapled to it. Keep the same line order and wording across both documents, show both figures wherever a quantity moved — “7.0 yd³ (estimated 6.5)” — and keep the proposal number in the header so the two tie together next spring.

Discovery lines are the ones that need care. Anything the excavation exposed, a soft subgrade needing extra stone or an unmarked line, goes on as its own dated line at the unit price the proposal already named. A price invented after the hole is open reads as opportunism no matter how fair it is.

What paperwork do I keep after the pour?

Both ready-mix tickets, the stone delivery ticket, the rebar and form lumber receipts, the color hardener and sealer receipts, the dump ticket for the spoil, the locate confirmation, and photos of the subgrade, the steel before the pour, and the finished slab. Keep the mix design and the psi with them. Those receipts are also your concrete business expenses at filing time, and the delivery tickets are the only proof that 4,000 psi went into the ground.

Keel handles that from the job. Photograph both tickets at the truck before they blow off the dash — Apple Intelligence reads them on the device, with no account, no bank connection, no cloud, no login, and an App Store privacy label that reads Data Not Collected. The invoice goes out the day the joints are cut, in about a minute, carrying your own numbering, your logo, your brand color, and a payment link printed as a QR code. Trips to the plant and the stone yard log as mileage. The $2,800 scheduling deposit was concrete money rather than profit, and Freeboard is the view that makes that obvious: cash minus tax reserve, minus committed work, minus a buffer. At year end the Accountant Pack exports a CSV and a one-page summary, and the whole year leaves as a single file. Free covers unlimited invoices, receipts, and mileage; Keel Pro is a one-time $249.99 Lifetime purchase, not a subscription.

Frequently asked questions

How do you calculate concrete yardage for an invoice?

Multiply area in square feet by thickness in feet and divide by 27, or use the shortcut divisor: square feet ÷ 81 for a 4 in slab, ÷ 54 for 6 in. This job was 456 sq ft at 4 in, or 5.63 yd³, plus 0.6 yd³ for the thickened edge. Order above the takeoff, since running short mid-pour leaves a permanent cold joint.

Should a concrete invoice show yards or square feet?

Both. Customers understand the surface they walk on, and yardage is what the plant sold you. Put the conversion in the header, price the ready-mix per yard on its own line with the ticket numbers, and price excavation, base, placement, and finish per square foot. That way the arithmetic is checkable and no line hides inside another.

Why is my concrete invoice so much more than the price of concrete?

Because the ready-mix is typically a small share of the job. On this invoice it is $1,372 of $8,588.80, or 16 percent. The rest is demolition, excavation and haul-off, base stone, forms, steel, placement labor, finishing, joints, cure, and sealer. Show those as separate lines and the total stops looking like a markup on concrete.

How do I charge for a pour with no truck access?

As its own line, priced per yard or per hour, and disclosed before the job is booked. Seven yards through a 36 in gate is around forty wheelbarrow loads and needs a bigger crew than a driveway pour. A line pump or a buggy is the alternative and carries a setup charge plus a minimum yardage — either way it belongs on the estimate, not as a surprise on the invoice.

Do control joints go on the invoice as a separate line?

Yes, by the linear foot, with the spacing and depth stated. Joints are cut roughly 24 to 30 times the slab thickness in inches, so an 8 to 10 ft grid on a 4 in slab, and about a quarter of the slab depth. Write the note that joints direct cracking rather than prevent it, because that sentence prevents a callback.

What does a concrete delivery ticket prove?

The yardage delivered, the mix design and strength, the batch and delivery times, and any admixture or water added on site. Staple both tickets to the invoice or reference their numbers on the concrete line. It is the strongest evidence you have that 4,000 psi air-entrained mix went into that patio, and it settles a yardage dispute in one look.
