How to Invoice After House Window Cleaning

Short answer: How to invoice after house window cleaning comes down to what you counted at the door. Bill by pane and by sash — a double-hung is two sashes with two sides each, a true divided lite counts per lite, and a triple-track storm is a separate unit that has to come out and go back. Put screens, tracks and sills on their own lines with counts. Note any pane you could not reach, credit it, and take payment before the ladder goes on the rack.

A homeowner standing in the driveway counts holes in the wall. You clean surfaces, and the two numbers are never the same. Nothing else in this trade produces as many small disagreements as that gap, and the invoice is where it either closes or turns into a phone call on Sunday. The fields every invoice needs are in what to include on an invoice; everything below is what only shows up on a house.

What does the invoice count that the homeowner did not?

Sashes, faces, and the units that came out of the frame.

Element	How it counts on the invoice	Why it is not one unit
Double-hung or single-hung opening	Two sashes, exterior and interior faces	Four surfaces plus a meeting rail per opening
Casement or awning	One sash, two faces, plus the crank arm gap	Hardware blocks the squeegee at one edge
Slider	Two panels, two faces, plus the overlap	The overlap is hand-detailed, not squeegeed
Picture or fixed plate	One pane, own class	Two-hand work, longer channel, sometimes two people
Triple-track storm	Its own unit, both panels	Lift out, wash, dry the track, reinstall
Screen	Its own unit	Removal, wash, dry, reinstall, and the risk of an old frame
Sliding patio door	Two panels, two faces, plus the track	The track is a separate line, and it is filthy
Transom, sidelight, half-round	Own class	Reach and shape, not size
Skylight or sunroom glass	Own class	Roof or interior ladder work over furniture
Basement hopper or egress	Own class	Ground-level dirt, window wells, spiders

Print the counts by class. A homeowner reading “whole house — $XXX” has nothing to check and every reason to argue. A homeowner reading 26 openings, 44 sashes, 88 faces, 22 screens, 14 storm panels is looking at arithmetic, and arithmetic does not argue back.

Do the grids on those windows add panes or not?

This one costs more money than any other counting question in residential work, and the answer depends on which side of the glass the grid is on.

Grilles between the glass sit inside the sealed unit. You wipe the pane as one surface and the grid never touches your squeegee. Simulated divided lites have muntin bars applied to the outer surface, which means every small rectangle has its own four edges and four corners to detail. True divided lites are separate pieces of glass entirely. Same window from twenty feet away, three completely different amounts of labor.

So the count sheet needs a grid column, and the invoice line needs to say which kind. A colonial-grid double-hung with applied bars, six over six, is twelve small detail areas per sash rather than one open pane. If you quoted that house as plain double-hungs, you already lost the money before you arrived. Look at the grid on the walk-around, put a finger on the glass, and write down which type it is. That single habit is worth more than any pricing spreadsheet.

Where do the numbers come from when the price was quoted over the phone?

From a recount at the door, before the first bucket comes off the truck.

Residential window cleaning is the one job routinely priced sight-unseen, off a square footage figure and a guess. The house that gets described as “a normal two-story colonial, maybe twenty windows” reliably has a sunroom, a bank of basement hoppers, a storm door, and a stairwell window nobody mentioned. Recount, then show the delta on the invoice with the phone estimate beside it.

What was different from the phone quote	What it does to the invoice
Grids turned out to be applied, not between glass	Detail class upgrade on the affected openings
Storm panels present and never mentioned	Storm line, per panel, with removal and reinstall
Interior added on arrival	Interior faces line, plus prep and protection
Sunroom, stairwell or half-round found	Own class, own count
Screens seized, painted in, or torn	Handling line, or excluded in writing
Second story sits over a deck rail or slope	Access class change for that elevation
Sills and tracks not cleared by the customer	Prep and handling line
Renovation dust, paint specks or overspray	Pretreatment or scraping, by opening

Show the original number, show the added lines, show the new total. Silently absorbing a delta teaches the customer that the phone quote is the real price, and next year the same house adds another surprise.

Which lines does a homeowner assume were included?

The ones that take the most time and never appear in the word “windows.”

• Screens, per screen, split into remove and reinstall versus wash. Old aluminum frames bend and old spline crumbles, so photograph any screen that arrives already damaged before you touch it.
• Storm panels, per panel. Triple-track storms are three units in one opening, and the bottom track holds fifteen years of grit.
• Tracks and sills, per opening, vacuumed before any water touches them. Water on a dry sill full of dirt makes mud, and mud on white vinyl is what the customer remembers.
• Frames and vinyl wipe-down, per opening, called out separately from the glass.
• Interior protection: shoe covers, drop cloths under every ladder foot, moving plants and lamps off sills.
• Access class per elevation: ground work, extension ladder, water-fed pole from grade, ladder over landscaping or hardscape. These carry different setup times and different risk, and a rear elevation that drops onto a retaining wall is not the same job as the front.
• Minimum charge on a small house or a partial. Drive, unload, set up, break down and reload cost nearly the same for ten panes as for sixty.

Each of those is a line with a count. Folded into one number, they are free work the customer did not know they received.

What goes on the paper about glass that did not come clean or never got reached?

Both belong on the invoice, and both are cheaper to write down than to explain later.

Mineral deposits from irrigation heads that hit the glass every morning are the common one. Given long enough, the minerals bond with the silica in the glass and the surface itself is altered, which is etching rather than soiling. A standard clean will not touch it and nothing on a store shelf reverses it. State the affected openings on the invoice as a condition, not as a failure, and quote restoration as a separate scope with a test panel first — you do a small area, show the result, and price the rest from what you actually saw. The same rule covers paint specks, adhesive from old film, and pitted glass from a nearby driveway.

Panes you decided not to reach need the same treatment. A second-story window over a stairwell with no safe ladder footing, a sealed picture window in a room the customer locked, a skylight you will not walk a wet roof for — list each one, credit it at zero, and write the reason in four words. A homeowner who finds an uncleaned window after you leave assumes you missed it. A homeowner holding an invoice that names it assumes you were careful.

What do you walk them through before you ask for money?

A two-minute loop, done in the same order every house.

Walk the front elevation, then the back, then whatever room had the worst interior glass. Point at the sills and tracks, because that is the work nobody expects and everybody notices. Hand over the invoice with the class counts visible. Say what you excluded and why. Show the two or three before-and-after photos on your phone for anything that was genuinely bad — the hard-water panes, the sunroom, the tracks. Say the guarantee out loud in one sentence: rain does not spot clean glass, and if there is a smudge or a run inside three days, call and I will come back.

That last sentence is worth doing carefully. Residential window cleaning is repeat work with a long memory, and the callback policy is the whole difference between a customer who books twice a year and one who buys the cheapest quote next spring.

How do you collect at the door on the same visit?

This is the trade’s advantage over almost everybody else on the block, so use it.

The person who hired you is standing there. Build the invoice on the tailgate while the crew loads, hand it over, and take the payment before the ladders are strapped. A payment link on the invoice, rendered as a QR code, turns that into fifteen seconds on their own phone with no card ever passing through your hands. Card, tap, transfer, check, cash — take whatever they have, then send the paid document. If they pay on the spot, what they need afterward is a receipt rather than an open invoice, and the difference between those two documents matters at tax time on both sides: see invoice vs receipt.

When nobody is home, leave the invoice with the counts and photograph the door hanger with a timestamp. Do not leave an unpriced note promising to send something later. The bill written on the day is the bill that gets paid on the day.

Does the per-pane number cover the drive and the setup?

Build it from your own clock, then check the market number afterward.

1. Time each class on real houses. Plain double-hung sash, applied-grid sash, picture window, storm panel, screen, patio slider. Six numbers, measured, not guessed.
2. Convert to cost per unit. Loaded hourly cost — wages plus burden, the van, ladders, the water-fed pole and filters, insurance — divided by units per hour.
3. Add consumables: rubber, DI resin per gallon of pure water, scrapers and blades, towels.
4. Add the fixed block for the stop: drive, unload, set up, break down, reload. On a small house this is most of the job, and it is why the minimum exists.
5. Add overhead per sold hour: annual fixed cost divided by hours you actually bill in a year.
6. Add profit as margin, not markup. A house that costs $186 marked up 40 percent invoices at $260 and keeps a 28.6 percent margin. To hold a true 40 percent margin you divide by 0.60 and invoice $310. Doing that backwards on every house is a full month of income over a season.

Published per-pane figures move enormously with region, house style, storm and screen prevalence, and how many stories you are working. Use them only to notice you are off by half. The economics change completely once the glass is commercial and repeatable, which is a different document — how to invoice after storefront window cleaning.

What stays in the file after the ladder is on the rack?

The count sheet by class, the phone quote next to the final total, photos of pre-existing damage and hard-water panes, the excluded list with reasons, the paid invoice, and the miles between houses.

Keel is an iOS app built to hold that on the phone alone: no account, no bank connection, no cloud, no login, and an App Store privacy label that reads Data Not Collected. You put each class on its own line — sashes, storm panels, screens, tracks and sills — build the PDF with your own numbering, logo and brand color, and hand it over at the door with the payment QR code already on it. Trips between houses go into the mileage log, which is the deduction most residential cleaners underclaim; what the log has to contain is in IRS mileage log requirements. Receipts for resin, rubber and blades get photographed and read on device with Apple Intelligence. The ledger is append-only and hash-chained, so a customer asking next spring what they paid in October gets a straight answer, and the whole year 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. You can get it on the App Store.

Frequently asked questions

How do you count windows for a residential window cleaning invoice?

Count sashes and faces, not openings. A double-hung has two sashes and each sash has an inside and an outside, so one opening is four surfaces. Sliders count per panel, storm panels count as their own units, and screens count separately because they have to come out and go back. Print the class counts on the invoice so the homeowner can check the math against the house.

Do window grids change the price?

Yes, and it depends on the type. Grilles sealed between the panes never touch your squeegee, so the pane cleans as one surface. Applied muntin bars and true divided lites turn one sash into six or twelve small detail areas with their own edges and corners. Identify the grid type during the walk-around and write it on the count sheet, because pricing an applied-grid house as plain glass loses the job before it starts.

What should be on a house window cleaning invoice besides the glass?

Screens per screen, storm panels per panel, tracks and sills per opening, frame wipe-down, interior protection, the access class used on each elevation, pretreatment for paint specks or mineral deposits, the panes you excluded and why, and a minimum charge on a small job. Each of those is real labor the phrase “cleaned the windows” hides.

Can hard water stains be removed from house windows?

Sometimes. Fresh mineral deposits come off with an acidic restoration product. Deposits left long enough bond with the silica in the glass and etch the surface, and that damage does not reverse. Test a small panel first, show the customer the result, and price restoration as a separate scope. Put the affected openings on the invoice as a stated condition so nobody thinks the clean failed.

Should I invoice a homeowner before or after cleaning the windows?

After, on the same visit, with the counts on the paper. Residential glass is a same-day job with the customer usually present, so there is no reason to extend credit. Build the invoice at the truck while the crew loads, walk the elevations, and take payment with a link or QR code before you strap the ladders.

Do I charge extra to remove and reinstall screens?

Yes, per screen, as its own line. Pulling a screen, washing it, drying it and putting it back is a separate operation from cleaning glass, and on a full house it can be a third of the visit. Photograph any screen that is already bent, torn or missing spline before you remove it, and note it on the invoice.
