Books and taxes for commercial window film installers.
A bid-won job on an office tower, film bought by the roll, a warranty callback on a bubbling install, and a crew paid by the square foot. Gus sorts all of it, an accountant checks every transaction, and you get one number a month.

September came in at $8,800. The heat gun and squeegee kit for the second crew went in as equipment, not a film order.

Why your books are different
Window film installation books go wrong in the same four places.
A generalist sees deposits and bills. Your business bids jobs one building at a time, buys film by the roll for a specific project, and stands behind installs with warranty work that costs money without a new invoice. When the books do not know that, job profit is a guess.
-
1
A deposit gets counted as income the day it lands
A deposit collected before starting a multi-day office tower job is not fully earned yet, and counting the whole thing as income the day it arrives makes the month look better than the work completed so far actually supports.
What we doBooks each deposit against the specific job it funds, so income counts as earned only as that job's work gets done. -
2
Warranty callbacks look like a loss with no job attached
A bubbling or peeling film panel that has to be redone under warranty costs labor and sometimes new film, but with no new invoice coming in, it can look like an unexplained expense instead of the cost of standing behind past work.
What we doKeeps warranty and rework costs in their own line tied to the original job, so you can see what a callback actually costs without it reading as a mystery loss. -
3
Film stock bought for one job gets mixed with general supplies
A roll of film ordered for a specific office tower job is a cost tied to that project, but mixed in with everyday material spending, you cannot tell what any single job actually cost to complete.
What we doKeeps film and materials tied to the job they were bought for, so job cost and job profit stay clear. -
4
Crew pay by the square foot hides real job cost
Paying an install crew by the square foot across several jobs running at once makes it hard to tell which job the labor cost actually belongs to, so an underbid job can hide inside an otherwise good month.
What we doTracks crew wages against the specific install they worked, so you can see what each job actually cost to staff.
Your categories
The categories Gus keeps for a window film installation company.
Set up once for how you get paid and what you spend. You never pick a category. He does, and an accountant checks it.
Money in
- Bid job depositsDeposits collected before a large job starts.
- Completed job billingFinal payment collected on job completion.
- Residential and small jobsSmaller single-day jobs billed on completion.
- Maintenance and reapplicationRepeat customers replacing older film, billed separately from new installs.
Money out
- Film and materialsWindow film rolls, adhesive, and squeegee kits tied to specific jobs.
- Crew laborInstall wages, tracked by the job they worked, whether hourly or by the square foot.
- Warranty and reworkLabor and material cost for callbacks on past installs.
- EquipmentHeat guns, cutting tables, and tools logged so they get written off right.
- Vehicle and routeFuel, insurance, and repairs for the install van fleet.
- Bid and marketing costsProposals sent to property managers and general contractors.
- Insurance and licensingGeneral liability, workers comp, and any state contractor licenses.
What we watch for you
- Install job margin
What each installation actually cleared after film cost and crew labor, tracked separately from the next job.
- Warranty callback rate
How often past jobs need rework, so a bad batch of film or a training gap gets caught early.
- Deposit aging
How long a deposit sits before the job wraps, so cash on hand is not mistaken for profit already earned.
Ask Gus
Things window film installers ask Gus.
Text him like you would text anybody. He answers in plain English, and when a question is above his pay grade, an accountant looks and gets back to you.
Not all at once. I keep it tied to that job, so it only counts as earned as the crew actually finishes the work, not the day the check lands.
I logged the redo as warranty and rework tied to that original job, so it is visible as the real cost of standing behind past work, not a random expense.
If you pay him $2,000 or more this year and he is not on payroll, he gets a 1099 by January 31. I keep that list current as each job wraps.
The tax side
The tax side of a window film installation business.
Most of what goes wrong here is labels and timing. A deposit counted as income too early, a second installer paid like a contractor who works like an employee, and a set-aside nobody started until the return was due.
What your return has to get right
Your accountant signs it, so it gets done right the first time.
- Tools and cutting equipmentHeat guns and cutting tables bought for the business can usually be written off the year you buy them, with bonus depreciation back to 100 percent for property acquired after January 19, 2025.
- Contractor 1099sA second installer paid $2,000 or more in 2026 who is not on payroll gets a 1099-NEC by January 31. Gus keeps that list current all year.
- Employee or contractorAn installer who works your job on your schedule with your tools is usually an employee, even if paid by the square foot. Getting that wrong gets expensive, so Gus asks before it becomes a habit.
- The pass-through deductionA profitable install crew owner can usually take up to 20 percent of business profit off taxable income under the pass-through deduction, once the books are right all year.

All year, not just April
A window film installation year, kept every month.
Bid jobs come in waves tied to building renovations and lease turnover, not a fixed calendar. Your team keeps you ahead of the swings. Every month in between, your bookkeeper closes the books and speaks up the moment something looks off.
- January
Bid year begins
Filing on last year's return begins, the second installer's 1099 gets confirmed, and the monthly set-aside starts building for the coming season.
- April
Filed and closed
The return is filed and signed this month. No scramble for cash, since the set-aside has been accumulating steadily since January.
- July
Midyear film check
Where you stand, what you will owe, and whether summer building projects changed the number.
- October
Before winter bids
As property managers push to finish projects before winter, Gus looks at tools worth buying and anything worth doing before December.

Straight answers
Questions window film installers ask first.
Can Gus track a job that gets billed in a deposit and a final payment?
Yes. Each deposit and final payment is tied to the specific job it funds, so income lines up with the work actually finished on that building, not with when a check happens to clear.
A callback on old work costs money with no new invoice. How does that get booked?
It gets logged as warranty and rework tied to the original job, so you can see what standing behind past work actually costs instead of it looking like a random expense.
Do I write off cutting tables and tools all at once?
Often you can. Tools bought for the business can usually be deducted in the year you buy them, though sometimes spreading the cost out is the better call. Gus flags the purchase and the accountant decides with your whole year in view.
My crew gets paid by the square foot across different jobs. Does that matter?
Yes. Crew wages get tracked against the specific install they worked, so you can see what each job really cost to staff instead of one payroll total for the week.
My books are a mess from the last few jobs. Is that a problem?
No. Send whatever statements you have, even mid-job. Gus sorts the deposits and completed billing, the accountant checks them, and you will know where you stand within a week.
Is a real accountant checking my books?
Yes. You get your own bookkeeper, Gus does the first pass on every transaction, and an accountant checks every one before your month closes. That same accountant prepares, signs, and files your business return. Goatkeeper is not a CPA firm, and we never pretend a person looked when they did not.
What does it cost, and can I cancel?
It starts at $197 a month, depending on what your business needs. No setup fee, no hourly bills, no contract. Cancel any time from the app, and your books go with you.
