How to Invoice After Patio Concrete, Line by Line

Short answer: How to invoice after patio concrete starts with the batch ticket, not your takeoff. A 14 ft by 20 ft slab is 280 sq ft, and at 4 inches that is 280 ÷ 81 = 3.46 cu yd, ordered at 3.75 or 4. Then bill the lines a backyard creates on its own: placement method, base and compaction, forms by the linear foot, joints, finish, and sealer. Collect at the tailgate.

A patio is the smallest concrete job that behaves like a big one. The yardage is trivial and the money is nowhere near the yardage — it is in getting three and a half yards through a thirty-six inch gate, in the pitch away from the house, and in a finish the customer will be looking at from a kitchen window every morning for twenty years. The general shape of the document is covered in what to include on an invoice. Below is what the paper looks like when the pour was a backyard slab.

What actually goes on a patio concrete invoice?

Twelve lines, and each one exists because it was a separate decision, a separate vendor, or a separate hour.

Line	Unit on the invoice	Why it stands alone
Demo and haul of the old patio	Sq ft removed, plus disposal by the ton or load	The scale ticket sets it, not you
Excavation and grading	Cu yd moved and hauled	Spoil takes more room loose than it did in the ground
Base stone and compaction	Tons delivered, passes compacted	The quarry bills weight; you spread volume
Placement method	Buggy, wheelbarrow, pump, or conveyor, by hour or trip	The single largest patio-specific cost
Ready-mix	Cubic yards, psi, admixtures, from the batch ticket	Third-party paper with the plant’s name on it
Short-load charge	Flat, per the plant’s threshold	A 3.5 yd order rarely prices like 3.5 yards
Forms and stakes	Linear feet of perimeter	Perimeter, not area, drives forming hours
Reinforcement	Sq ft of mesh or linear feet of rebar, with chairs	Steel and the labor to keep it off the dirt
Finish	Sq ft, named — broom, trowel, exposed, stamped	Different operations, different crew sizes
Joints	Linear feet cut, plus the isolation joint at the house	A return trip on the concrete’s schedule
Sealer	Sq ft, on a separate visit	Another day, another product, a maintenance sale
Site restoration	Flat or hourly	Sod, ruts, a fence panel put back

Name the patio on the invoice the way the customer names it — “rear patio off kitchen slider, 14 × 20” — because in two years they will call about the side walk and neither of you will remember which slab this was.

Where do the cubic yards on the invoice come from?

The batch ticket. Your takeoff is what you ordered; the ticket is what was delivered, and the ticket is what the customer sees.

The takeoff arithmetic is one line: area in square feet times thickness in feet, divided by 27. At 4 inches that is square feet divided by 81. A 14 by 20 patio is 280 sq ft, so 280 ÷ 81 = 3.46 cu yd. At 5 inches, because a hot tub or a heavy outdoor kitchen is going on part of it, divide by 64.8 instead and the same footprint becomes 4.32.

Then read what actually happened. The ticket carries the yards, the mix design, the specified strength in psi, the admixtures, and any water added on site. Print those on the invoice. A customer looking at “3.75 cu yd, 4000 psi, fiber, air entrained” next to a plant’s ticket has nothing to argue with, and a customer looking at “concrete: $X” has an evening to fill.

One patio-specific line belongs next to the yardage. Plants set a minimum load and a surcharge below it, and almost every residential patio lands under that threshold. That charge is real, it is on the plant’s rate sheet, and it should be on your estimate and your invoice as its own item rather than buried in a per-square-foot number that was built on driveways. Ask your plant where their threshold sits before you quote the next small slab.

Why does placement get its own line on a backyard job?

Because the truck cannot reach the pour, and everything that follows from that is labor nobody sees in a square-foot price.

A driveway is poured off the chute. A patio behind a house is poured through whatever opening exists. Measure the gate before you quote, because a powered buggy will not fit through a standard thirty-six inch gate and a wheelbarrow relay is the fallback.

Method	What it needs	What it does to the day
Direct chute	Truck within reach of the forms	Fastest, and rare on a patio
Wheelbarrow relay	Plank runway, plywood over lawn, bodies	Roughly 9 loads per cubic yard at 3 cu ft a barrow — about 32 trips for 3.5 yards
Powered buggy	A gate or side yard wide enough, and firm ground	Fast, but only if the opening allows it
Conveyor	Setup room at the curb and reach to the slab	A vendor with its own minimum
Line pump	Hose run through the side yard, plus a washout location	A vendor minimum charge whether it runs one hour or four
Fence panel removed and reset	Screws, help, and a rebuild at the end	An hour at each end of the day

Thirty-two wheelbarrow trips is not a detail, it is a crew size. It is also why a small patio can cost more per square foot than a large driveway, and why that sentence has to be said at the estimate rather than defended on the invoice. Add the washout location, the plywood and plank protection over the lawn, and the sod repair where the runway sat.

How do slope, joints, and the tie-in to the house show up on the paper?

As line items, because each one is a decision that protects the customer’s house and each one is work a cheaper bid skipped.

Exterior slabs are pitched away from the structure. The common standard is a two percent fall, which is a quarter inch of drop per foot of run, so a patio that extends 14 feet from the wall drops about three and a half inches from the house side to the far edge. That is not cosmetic. A slab pitched the wrong way sends roof and surface water at a foundation, and it is one of the more common causes of water in a basement. Put the pitch on the invoice — “graded to fall away from structure at approximately 1/4 in per ft” — because it is the line that separates your slab from the neighbor’s.

The joints are two different things and both get billed.

• The isolation joint where the slab meets the house or a stoop, so the patio can move without pushing on the foundation. Linear feet of the tie-in edge, plus the expansion material.
• Control joints, cut so the slab cracks where you decided. Common guidance for unreinforced slabs on grade spaces them at roughly 24 to 36 times the slab thickness, which puts a 4 inch patio somewhere in the 8 to 12 foot range, cut at least a quarter of the depth. Bill them by the linear foot cut.

Say on the invoice what a control joint is for. A hairline appearing inside a saw cut in month four is the design working, and a customer who was told that on invoice day does not call it a defect in the spring.

What changed between the estimate and the invoice?

On a patio, usually something, because most of the surprises are under the sod.

What turned up	How it lands on the invoice
The old patio was 5 inches thick, not 3	Additional demo hours and a heavier disposal ticket
Soft fill or a buried stump under the footprint	Extra excavation by the yard, extra base tonnage
Grade never allowed the pitch without dropping the far edge	Added excavation, or a step and a riser as its own line
The gate would not take the buggy	Placement changed to wheelbarrow relay, hours added
Customer upgraded from broom to stamped after seeing a sample	Mats, release, color, and a sealer visit, priced as one change
A hot tub was mentioned after the forms went in	Thickened section and heavier reinforcement, and a thickness change on the ticket
Downspout discharge dumped onto the new slab	A trench and pipe under the patio, or a decision documented in writing

Each of those goes on its own line with the date it was approved, and each should be readable in ten seconds against the estimate. Where the deposit sat in that sequence, and which of these got billed before the truck rolled rather than after, is a question of billing timing rather than line items — that sequence is set out in when should a concrete contractor invoice.

What gets handed over the day the joints are cut?

Five things, and they take about four minutes at the tailgate.

• The batch tickets and the quarry scale tickets. Third-party documents that back the two largest material lines.
• Before and after photos from the same corner, ideally including the dig, the base, and the steel before the pour. Everything you did well is buried by lunchtime.
• A use schedule in plain words. Foot traffic typically after a day or two, patio furniture once the slab has had a week, and heavy loads — a full hot tub, a stone fire pit, a vehicle if the slab is near a drive — held to the full strength period. Print it, because a hot tub filled on day four is a claim you will be arguing rather than a mistake the customer made.
• The joint explanation and the efflorescence warning. A white bloom on a new exterior slab is salts moving to the surface, not a failure, and it usually fades. That one sentence prevents a call in week three.
• The sealer plan. Whether it is included, when the return visit is scheduled, and what recoating interval the product calls for. Decorative work in particular sells its own maintenance.

How do I collect standing at the truck?

Do the walk while the slab is still dark and the forms are still on. That is the best the job will ever look and it is the moment it is worth the most to the person paying.

Walk the perimeter once. Point at the pitch, the joints, the isolation strip at the house, and the finish as you pass them. Then hand over the invoice on your phone with the payment link rendered as a QR code and take payment before the trailer is loaded. Two minutes in a backyard beats an evening of paperwork and a follow-up call in week two, when the slab has lightened and a hairline has appeared exactly where you cut for it. Once the payment clears, what the customer gets back is a receipt rather than a second invoice, and the difference between the two is set out in invoice vs receipt. A drive pours and bills on a different rhythm entirely, covered in how to invoice after driveway concrete.

What do I keep once the patio invoice is paid?

The measured takeoff, the batch tickets, the quarry scale tickets, the disposal ticket, the pump or conveyor invoice, the dated change orders, the pre-pour photos of base and steel, the use schedule you handed over, and the invoice with the receipt.

Keel exists for the version of this that happens with wet boots in somebody’s backyard. It is an iOS app that runs entirely on the device: no account, no bank connection, no cloud, no login, and an App Store privacy label reading Data Not Collected — which on a lot with one bar of signal is the difference between invoicing today and invoicing Sunday night. The invoice carries your numbering series, logo, and brand color, with lines at whatever unit the scope used: cubic yards from the ticket, tons of base, linear feet of form and joint, square feet of finish, and the buggy hours. Batch tickets and scale tickets get photographed at the truck and read on device by Apple Intelligence, so the yardage you were charged for stays attached to the slab you poured it into. Plant and quarry runs log as mileage. Freeboard shows cash minus tax reserve minus committed invoices minus your buffer, which for a trade that pays for material on delivery is the number that says whether Thursday’s pour is funded. The ledger is append-only and hash-chained, and the year exports as one file or as an Accountant Pack of CSV plus a one-page summary PDF. Free is $0 with unlimited invoices, receipts, and mileage; Keel Pro is a one-time $249.99 Lifetime purchase, not a subscription.

Frequently asked questions

How many cubic yards is a patio slab?

Multiply the area in square feet by the thickness in feet and divide by 27. At 4 inches the shortcut is square feet divided by 81, so a 14 by 20 patio at 280 sq ft is 3.46 cu yd and gets ordered at 3.75 or 4. At 5 inches divide by 64.8 instead. Invoice the yards shown on the batch ticket, not your takeoff.

Should a patio invoice show the concrete separately from the labor?

Yes, and it makes the price easier to defend rather than harder. Ready-mix, short-load charge, base stone, steel, and any pump or conveyor are vendor costs with tickets behind them. Placement, forming, finishing, and joint cutting are your hours. A customer who can see which is which stops treating the total as a single negotiable number.

Why does a small backyard patio cost more per square foot than a driveway?

Because the truck cannot reach it. Three and a half yards moved by wheelbarrow is roughly 32 trips at 9 loads to the yard, plus plank runways, lawn protection, and often a fence panel removed and reset. Add a short-load surcharge on a below-minimum order and the fixed costs of a small pour land on very little square footage.

How much should a concrete patio slope?

The common standard is two percent, a quarter inch of drop per foot of run, falling away from the house. A patio extending 14 feet from the wall drops about three and a half inches across. Wet climates sometimes call for more. Write the pitch on the invoice, because a slab that drains toward a foundation is the expensive kind of mistake.

When can the customer put furniture on a new patio?

Foot traffic is usually fine after a day or two, patio furniture after about a week, and anything heavy — a filled hot tub, a stone fire pit, a vehicle — waits for full design strength. Print the schedule on the invoice on pour day. It costs six lines and it prevents the callback where something heavy landed on a four-day-old slab.

Do I charge for sealing a stamped patio separately?

Yes, because it is a different day, a different product, and a recurring service. Show it on the invoice either as an included line with the return visit dated, or as a quoted option with the recoating interval the product calls for. Decorative flatwork sells its own maintenance, and a customer told about it on pour day usually books it.
