Tile Installation Invoice Template: Square Feet, Waste, Prep

Short answer: A tile installation invoice template bills square feet at a rate set by tile size and pattern, then lists everything under the tile as its own lines. Show the waste factor you ordered against — roughly 7 to 10 percent for a straight lay, 15 to 20 percent for diagonal or herringbone — plus substrate, waterproofing, and heat mat by the square foot, edge trim by the linear foot, and demolition separately.

A tile invoice has an unusual problem: most of what the customer paid for is buried under the part they can see. Membrane, leveler, waterproofing, and the flood test are the difference between a bathroom that lasts twenty years and one that fails in three, and none of it shows up in a photo. The pre-job document is in tile estimate template, and the general field list is in what to include on an invoice.

What has to be on a tile installation invoice?

Eight blocks. The tile spec block is the one that stops most disputes before they start.

Block	What it has to say
Areas and square footage	Each surface separately — floor, walls, shower pan, wainscot — with its own footage
Tile spec	Size, material, finish, pattern, joint width, and who supplied it
Substrate work	What was under the tile before, what you did to it, what you installed
Waterproofing	System used, where it went, and the flood test with its duration
Setting materials	Mortar type, grout type, sealant at changes of plane
Trim and profiles	Edge profile by linear foot, bullnose count, thresholds, transitions
Demolition	What came out, footage, and where it went
Cure and use	When it can be walked on, when it can be grouted, when the shower can be used

Say plainly who supplied the tile. Homeowners buy their own tile on most residential bathrooms, and that single sentence on the invoice decides who pays when the order runs short, when a box is a different lot number, or when three pieces break on the wet saw.

Why does the invoice separate what is set from what goes under it?

Because they are separate purchases and one of them is invisible. A customer who sees a single line reading “tile bathroom, $4,900” believes they bought tile. A customer who sees leveler, membrane, waterproofing, and a flood test as their own lines understands they bought a system.

There is also a technical reason the substrate line exists. Flatness requirements tighten with tile size: the industry standard for tile with any edge 15 inches or longer calls for the substrate to be flat within 1/8 inch in 10 feet, and 1/16 inch in 24 inches, against a looser tolerance for smaller tile. A subfloor that was fine for 4x4 ceramic is not automatically fine for 12x24 porcelain. That is why the customer who upgraded to a large-format tile got a leveler line they did not have on the first estimate, and the invoice is where that connection gets made in one sentence.

Under the tile	Unit	When it appears
Demolition and haul-off	sq ft	Existing floor or wall covering comes out
Flatness correction	sq ft or bags	Large-format tile, or a subfloor that failed the straightedge
Backer board or uncoupling membrane	sq ft	Wet areas, plywood subfloors, crack-prone slabs
Waterproofing	sq ft	Showers, tub surrounds, curbs, benches, steam
Electric heat mat	sq ft of mat	Ohm readings recorded before, during, and after the set
Preslope and drain	job	Mud pan work, drain height set to finished floor

The demolition line carries one condition worth knowing before you quote it. Resilient flooring and mastic in houses built before the 1980s can contain asbestos, and EPA’s asbestos guidance covers what that means for renovation and demolition work. If the old floor is 9x9 vinyl tile on a black adhesive, the demolition line stops being a demolition line and becomes a testing line followed by somebody else’s scope.

How does waste appear on the invoice when the customer bought the tile?

As a stated factor with the reason attached, in the tile spec block rather than as a charge.

Layout	Typical waste allowance	Why
Straight or stack, square room	7-10%	Perimeter cuts only
One-third or half offset	10%	Cut pieces from one row often start the next
Diagonal	15-20%	Every perimeter piece is an angle cut with an unusable remainder
Herringbone, chevron, basketweave	15-20% or more	Two cuts per perimeter piece, and pattern direction wastes the offcut
Small room with many obstacles	Higher than footage suggests	A 42 sq ft bath can cut like an 80 sq ft one

Write the ordered quantity, the installed quantity, and the leftover you handed back as attic stock. When a customer supplied exactly the square footage on a herringbone floor and the job stopped two rows short, the invoice showing the waste factor you specified in writing is the entire conversation.

What does a filled-in tile invoice look like?

Placeholder rates from one setter so the arithmetic is visible. Replace them with your own.

Invoice total 4,914.30 · Deposit at contract 1,500.00 · Balance due 3,414.30

Lines 1 through 5 add up to 1,583.30 — 32 percent of the ticket — and none of it will ever be visible. That block is the first thing a customer asks to cut, and the only defense is having it printed as work rather than hidden inside a per-square-foot number.

Tile is absent from the invoice entirely because the homeowner bought it. The header says so. Attic stock returned: 1 box floor tile, 2 boxes wall tile.

How do I bill a small bathroom where the footage is low and the cuts are not?

By stating the cut count and the layout condition on the line, and by pricing that surface at a different rate than an open floor.

A 42-square-foot bathroom floor has a toilet flange, a vanity toe kick, a door jamb to undercut, a curb, and four walls that are not square to each other. Thirty-plus cuts on 42 square feet. An open 400-square-foot living area might have forty cuts total. The square footage says one job is a tenth of the other; the clock says nothing of the kind.

Surface	Why it costs more than a flat open floor
Bathroom floor	Cut density per square foot, fixtures, undercuts, no run of full tile
Shower walls	Vertical work, every piece supported until it grabs, plumb and level enforced in two directions
Shower floor	Mosaic cut into a slope toward a drain, sheets trimmed piece by piece
Backsplash	Outlets, window returns, cabinet ends, short runs, high visibility
Ceiling	Overhead, everything held, the slowest surface in the trade

Two honest ways to show this. Either quote a higher square-foot rate for the surface and say why on the line, or set a minimum charge per room. What does not work is one blended rate across the whole house, because the small rooms then subsidize nothing and the open rooms carry them.

What does the invoice have to say about grout, sealing, and when the floor can be used?

The cure windows, in dates, taken from the bags you used.

Mortar has to cure before grout goes in. Grout has to cure before a sealer or before water hits it. A flood test runs its full duration before anything gets tiled over it. Those intervals come off the product data sheet, and they stretch in cold or humid conditions — which is precisely why an invoice that says “do not use the shower until Thursday” beats one that says “allow to cure.”

Print four things: mortar type and when it was set, grout type and joint width, sealer product and whether it was applied or is the customer’s responsibility, and the earliest date for foot traffic, for the shower, and for heavy furniture. Add the maintenance sentence about what not to clean it with. That block is why callbacks about hazing, efflorescence, and cracked grout in the first month go from an argument to a reference.

How do I know the square-foot rate paid for the day?

Build it from a real production day and your own costs.

Production rate. Time a full day on one surface type and divide finished square footage by crew hours. Large-format porcelain on an open floor and 2x2 mosaic on a shower pan produce wildly different numbers, and that gap is the entire reason a single blended rate fails. Keep a short log of your own rates by surface; after ten jobs you are estimating from evidence.

Setting material cost per square foot. Mortar coverage per bag at the trowel you actually use, membrane per roll, grout per pound at your joint width, sealant, screws, blades. Diamond blades are consumable on porcelain and belong in this number, not in a mental “cost of doing business” bucket.

Labor. Your loaded hourly cost — pay, payroll tax, insurance, vehicle — divided by the production rate for that surface.

Overhead per day on site. Truck, tools, saw, insurance, phone, and dump fees, spread across the days you are actually installing in a month, not across the days on the calendar.

Margin, and the mistake. On the bathroom above, membrane, mortar, grout, trim, and blades came to about $6.10 a square foot. Add a 30 percent markup and you charge $7.93, of which $1.83 is 23 percent — not 30. A 30 percent margin means dividing cost by 0.70, which is $8.71. Markup measures against what you paid, margin against what you charge, and confusing them is why a shop can be booked out three months and still short at the end of the year.

Published per-square-foot ranges swing enormously with region, tile size, pattern, and how cut-up the space is. Use them to confirm you are not off by a multiple, then trust your own production log. A closely related build-up for other floor coverings is in how to estimate flooring jobs.

When does a tile customer pay?

In stages, because a bathroom is a multi-day job and the material is committed early.

A deposit at contract covers setting materials and the membrane order. A progress payment when the waterproofing passes its flood test is a natural, defensible checkpoint — it is a genuine milestone and the photos prove it. The balance comes due at final walkthrough, after grout and silicone, with the cure dates printed on the page.

Send the invoice the same day the work finishes and take payment on the spot with a scanned link. If the customer wants a paid receipt afterward for their remodel file, the difference between the two documents is covered in invoice vs receipt.

What do I keep after the tile invoice goes out?

Photos of everything that got covered — subfloor, membrane seams, flood test with a timestamp, heat mat with the ohm readings written on a piece of tape in the frame — plus the tile lot numbers, the setting material receipts, and the signed change orders. A shower leak two years out is settled by that folder or it is settled by whoever has better paperwork.

Keel 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 that reads Data Not Collected. The invoice gets raised on site with each surface as its own line and the cure dates typed into the terms, using your own numbering sequence, your logo and brand color, and a payment link the customer scans as a QR code at the walkthrough. The tile shop receipt for eight bags of mortar and a roll of membrane is photographed at the counter and read on device by Apple Intelligence, so the setting-material cost you keep forgetting to count becomes a number you can see. Supply runs are logged as trips. The ledger is append-only and hash-chained, so a flood test date recorded that week stays as recorded. At year end it exports as one file, or as the Accountant Pack: a 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

What should a tile installation invoice include?

Each surface with its own square footage, the tile size, material, pattern, joint width, and who supplied it, all substrate work as separate lines, the waterproofing system with its flood test duration, mortar and grout types, edge profiles by linear foot, demolition footage and disposal, change orders with dates, and the cure windows for traffic and for shower use.

Should the substrate be a separate line on a tile invoice?

Yes, always. Leveler, backer board, uncoupling membrane, waterproofing, and preslope are what the tile depends on, and none of it is visible when the job is finished. Rolled into a single per-square-foot number, it reads as padding and gets negotiated away. Listed as its own lines with footage, it reads as the work it is.

How much waste should a tile invoice show?

State the factor you ordered against and why: roughly 7 to 10 percent for a straight lay, about 10 percent for an offset, and 15 to 20 percent or more for diagonal, herringbone, or chevron, since those patterns produce two angled cuts per perimeter piece. Record ordered quantity, installed quantity, and attic stock handed back.

Why does a small bathroom cost more per square foot than a big open floor?

Cut density. A 42-square-foot bathroom floor can carry thirty or more cuts around a flange, a vanity, a curb, and out-of-square walls, while a large open room may have forty cuts in total. Square footage measures material, not hours, so small rooms need either a higher rate for the surface or a stated room minimum.

Do I put the tile itself on the invoice if the homeowner bought it?

No, but say so in the header. Write that tile was supplied by the customer, record the lot numbers, and note what was returned as attic stock. That single line decides who pays when an order runs short mid-job, when a second delivery arrives from a different lot, or when pieces break during cutting.

When can the customer use the shower after tiling?

Print an actual date, not a phrase. Mortar cures before grout goes in, grout cures before water hits it, and both stretch in cold or humid conditions. Take the intervals from the product data sheets for the specific mortar and grout you used, then write the earliest date for foot traffic and the earliest date for shower use directly on the invoice.
