How to Invoice After Storefront Window Cleaning

Short answer: How to invoice after storefront window cleaning starts with counting lites, not frontage. Each fixed lite between mullions is one pane, a door leaf is two faces plus the push plate and kick plate, and a vestibule is four leaves. Bill decal removal, gum and adhesive, hood grease film and film-safe cleaning as their own lines. A six-lite stop costs nearly what a twenty-lite stop costs to reach, so apply the minimum. Name the payer and their title on the invoice.

Storefront glass looks like the simplest work in the trade. It is at ground level, there are no screens, no storms and no furniture to move, and the whole stop can be over in fifteen minutes. What makes the invoice difficult is everything attached to the glass — vinyl lettering, delivery-app stickers, an interior film with a warranty on it, a fryer hood twenty feet upwind — and the fact that the person watching you work usually cannot pay you. The fields any invoice needs are in what to include on an invoice; the rest of this is what only happens on a sidewalk.

What does a storefront invoice count that a house invoice never does?

Lites between mullions, door leaves, and the glass that belongs to somebody else’s lease.

Element	How it counts	Why it is its own line
Fixed display lite between mullions	One per lite, per face in scope	The mullion is the boundary, not the opening
Transom above the header	Own class	Above reach, so pole or ladder, not a squeegee from the ground
Entry door leaf	One leaf, two faces	The dirtiest and slowest glass in the building
Vestibule or airlock	Two sets, four leaves	The inner doors are almost never in the quote
Sidelight beside the entry	Own count	Narrow and framed, hand-detailed at both edges
Drive-through window	Own class	Grease and receipt tape, and it stays in service while you work
Interior partition, cooler door, display case	Own class if in scope	Assumed included by the tenant, never priced
Second-story office glass over the shop	Own class	Different access, different insurance, different rate
Neighbor’s shared vestibule glass	Own line, own payer	It is common area, and the tenant does not pay for it

Two things belong on the face of the invoice above all that. Write whether the price is exterior only, because exterior-only is the default assumption in storefront work and the tenant’s assumption is often the opposite. And write the lite count, so a district manager comparing three vendors is comparing quantities instead of guessing.

Why does applied film change what you can bill and what you can touch?

Because the interior surface of commercial glass frequently is not glass, and treating it like glass destroys it.

Solar, security and decorative films are common on retail frontage, and their care rules are strict. Manufacturers instruct that you never use razor blades, scrapers or abrasive compounds on window film, and ammonia-based cleaners break down the film and its adhesive and can void the warranty. Newly installed film also needs a cure period before anybody cleans it at all.

That has three effects on your paper. Filmed interior faces are slower, because the blade you would normally reach for is off the table and every mark has to come off with solution and a soft cloth. Filmed lites need to be identified on the count sheet the first time you clean the account and then named on every invoice after — six lites, east elevation, interior film, cleaned film-safe with ammonia-free solution and no blade. And any scratch, bubble or delamination that was there before you arrived needs a dated photograph. A scratched film panel is expensive, it is indistinguishable from careless work, and the invoice line plus the photo is the only thing standing between you and paying for somebody else’s tenant improvement.

Which lines come off the doors instead of the glass?

The entry set is where the labor actually is, and none of it is glass.

• Push plate, pull handle and kick plate, per leaf. Handle height is a band of skin oil that solution alone will not take off.
• Door frame and threshold, per leaf, including the track on a slider.
• Decals and vinyl lettering: hours of operation, logo, health grade, credit card and delivery-app stickers, and whatever the last promo left behind. Bill removal per decal or by area, and never remove one without asking, because some of them are legally required to be posted.
• Tape, adhesive and poster residue from the inside, which is a different chemistry and a different tool from the outside.
• Gum, stickers and flyers at street level.
• Grease film, on and near any food service tenant. Exhaust hood and fryer vent discharge settles on the frontage, needs a degreaser rather than soap, and is the reason the pizza shop takes twice as long as the phone store at the same lite count. Price it as a soil class, not as an afterthought.
• Winter salt spray and low-glass kick marks, which are seasonal and belong on the invoice when they show up.
• Minimum charge for the stop. Drive, park, unload and walk cost the same whether the frontage is six lites or twenty.

What changed between the walk-up quote and the finished stop?

Storefront quotes get given in ninety seconds from the sidewalk, so drift is normal. Print it.

What was different	What it does to the invoice
New decals or a seasonal window wrap since the quote	Removal line, per decal or by area
Interior film found on an elevation	Film-safe class on those lites, and a condition note
Interior added on arrival	Interior faces line, plus working around customers
A second tenant’s glass in the same bay	Separate line and possibly a separate payer
Vestibule inner doors not in the original count	Four leaves, not two
Awning or transom nobody mentioned	Access class change for that section
Construction or a road crew next door	Pretreatment, or a return visit
The store was mid-rush and the entry was unusable	Time on site line, or a rescheduled entry set

Show the quoted number, the added lines, and the new total. Absorbing the difference quietly is how a route stop that was profitable in March is losing money by August.

Who at the store is actually allowed to pay you?

This single question decides whether the invoice gets paid today or in six weeks, and it is worth settling before the first clean rather than after.

Who is standing there	What they can actually do
Owner-operator	Pay in full on the spot
Franchisee	Usually pays, but from their own account, not corporate
Shift lead or key holder	Confirm the work happened. Nothing else
District or regional manager	Approve the work, then route it to accounts payable on terms
Corporate chain	Vendor onboarding, W-9, certificate of insurance, PO number, portal, net terms
Multi-unit restaurant group	One AP contact for many addresses; consolidate rather than invoice each store
Landlord or property manager	Pays for common glass, vestibules and shared frontage under the CAM budget

The expensive mistake in this trade is billing the wrong one of those two rows at the bottom. Common-area glass in a strip center is frequently the landlord’s cost, and a tenant who receives an invoice for it does not pay it, does not forward it, and does not tell you. Ask on day one who owns the vestibule glass, and put the answer in the account file.

Whoever pays, print their name and title on the invoice. A signature from a nineteen-year-old key holder is a record that you were there, not an approval that money is owed, and knowing the difference before you send anything saves the argument.

What do you leave behind when the store is open and busy?

A finished frontage, a document, and thirty seconds of conversation with the right person.

Take one timestamped photo of the completed frontage from the parking lot, and one of anything you excluded — a filmed panel you would not blade, a decal the tenant asked you to leave, a drive-through you could not reach during service. Hand the invoice to whoever can act on it, and if that person is not on site, say so out loud to whoever is and note it on the document. State the callback line in one sentence: rain does not spot clean glass, and if there is a smudge inside three days, call and I will stop back on the next route day.

If you worked around a delivery, a line at the register or a blocked entry, write the time on site. That note costs nothing today and is the entire basis for a rate conversation at renewal.

Is this the one-time rate or the route rate?

Say which one it is on the invoice, because a number that is not labeled becomes the standing rate by default.

Storefront per-lite pricing is low for one reason: you are already on the block, the stop is short, and the drive is shared across a dozen accounts. A first-time or one-off clean has none of that. The whole drive, the parking, and the setup fall on a single stop, and the glass is usually far worse than route glass because nobody has touched it in a year. That is a different job at a different price.

Print it plainly. One-time storefront clean, followed by the route rate you would charge at a stated frequency. That way the customer sees the discount rather than assuming the low number was always available, and the account starts at the right number instead of being renegotiated later. Once the account is on a schedule the billing mechanics change again, and that is covered in how to invoice after a recurring window cleaning contract.

Does the per-pane number survive a single stop?

Build the cost of the stop first, then divide by lites and see whether your per-lite number was ever real.

1. Time the whole stop, door to door. Drive from the last account, find parking, walk in with the kit, clean, break down, walk back. On short frontage, the glass is often less than half of it.
2. Cost that time at your loaded hourly rate — wages plus burden, the van, fuel, the pole and filters, insurance, and parking, which downtown is a genuine line item.
3. Add soil-class time separately. Grease frontage, filmed interiors and decal removal are not the baseline, and averaging them into one per-lite number means the food tenants are subsidized by the retail ones.
4. Add overhead per sold hour, from annual fixed cost divided by the hours you actually bill.
5. Add profit as margin, not markup. A stop that costs $38 marked up 45 percent invoices at $55 and keeps a 31 percent margin. To hold a true 45 percent you divide by 0.55 and invoice $69. On four hundred stops a season that gap is the difference between a second van and no second van.
6. Set a per-stop minimum and hold it, especially on the six-lite tenant at the end of the row.

Published per-pane storefront figures are a sanity check only. They move with route density, city parking, soil class, frequency and how many food tenants are in the center. Use them to notice you are off by half. The economics on a house work in the opposite direction, with a long setup and a single address, in how to invoice after house window cleaning.

What do you keep when the invoice is one short stop?

The lite count by class, the filmed elevations, dated photos of pre-existing film and glass damage, the payer’s name and title, the one-time versus route rate label, the excluded items, and the miles between stops.

Keel is an iOS app that keeps 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. A stop invoice takes under a minute on the sidewalk with your own numbering, logo and brand color, and the payment link prints as a QR code the owner scans at the register before you get back in the van, which turns an open invoice into a paid receipt before you have left the parking lot. The miles between accounts are the deduction storefront cleaners lose most often, since a route day is dozens of short hops that never feel worth logging; the method is in how to track mileage for taxes. Squeegee rubber, solution and parking receipts get photographed and read on device with Apple Intelligence. The ledger is append-only and hash-chained, which matters when a regional manager asks in November what a store paid in June, and the 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 panes on a storefront window cleaning invoice?

Count each fixed lite between mullions as one pane, and count faces separately when interior work is in scope. Door leaves count individually and carry hardware work with them, a vestibule is four leaves rather than two, and transoms, sidelights and drive-through windows each get their own class. Print the count on the invoice so a district manager comparing vendors is comparing quantities rather than guessing.

Can you use a razor blade on storefront glass?

Not on filmed glass. Solar, security and decorative films are common on retail frontage, and manufacturers instruct that blades, scrapers, abrasive pads and ammonia-based cleaners must never be used, since they scratch the film or break down its adhesive and can void the warranty. Identify filmed elevations on the first visit, photograph any existing scratches or bubbling, and note film-safe cleaning on every invoice for that account.

Should storefront window cleaning be invoiced per visit or monthly?

It depends entirely on who pays. An owner-operator or franchisee pays at the counter on the day, so a per-visit invoice with a payment link is the fastest money in the trade. A corporate chain or property manager pays through accounts payable on terms, and they generally want one consolidated invoice per period with a visit log and a purchase order number rather than a stack of small ones.

Who pays for cleaning the shared vestibule glass in a strip mall?

Usually the landlord, out of the common area maintenance budget, not the individual tenant. Settle it before the first clean and write the answer into the account file, because a tenant who receives an invoice for common-area glass will not pay it, will not forward it, and will not tell you. Bill common glass on its own document to the property manager.

How do I charge for removing decals and stickers from storefront windows?

As its own line, priced per decal or by area, and quoted before you touch anything. Vinyl lettering, promotional wraps and delivery-app stickers leave adhesive that is a separate operation from cleaning glass. Ask first, because some postings — health grades, licenses, hours — may be required to stay up, and removing one the tenant needed is a problem no invoice line fixes.

Why does a restaurant storefront cost more than the shop next door?

Exhaust hood and fryer vent discharge settles as a grease film on the frontage, and grease needs a degreaser and a second pass rather than soap and a squeegee. At an identical lite count the food tenant can take twice the time. Price it as a soil class on the account rather than averaging it into a single per-lite number, or the retail tenants in the center end up subsidizing the kitchen.
